GoldHaven Resources Advances Drilling with Second Hole Completed on Copeçal Gold Project

VANCOUVER, British Columbia, Oct. 21, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (CSE: GOH | OTCQB: GHVNF | Frankfurt: 4QS) (“GoldHaven” or the “Company”) is pleased to announce the successful completion of its second diamond drill hole (COP-002) at the East Target of its 100%-owned Copeçal Project, located in Mato Grosso State, Brazil.

Highlights:

  • Second diamond drill hole (COP-002) completed to a depth of 121 metres.
  • Enhanced alteration and veining intensity observed relative to COP-001.
  • Intersections include zones of silicification, biotite, quartz veining, sericite-chlorite, and weak carbonate alteration — features commonly associated with hydrothermal gold systems.
  • Geological and structural logging underway; sampling in progress for gold and multi-element analysis.
  • Drill rig mobilized to third pad, 100 metres west along strike from COP-001 and COP-002.

Drill hole CP-24-002 was advanced to a total downhole depth of 121 metres, intersecting lithologies consistent with those observed in the nearby first hole (COP-001). Importantly, the second hole displayed notable enhancements in alteration and veining intensity, including broader zones of silicification, localized biotite alteration, and quartz veining accompanied by sericite-chlorite and weak carbonate alteration. These alteration assemblages are often indicative of hydrothermal fluid activity associated with gold mineralizing systems.

Detailed geological and structural logging of both COP-001 and COP-002 is currently underway. Sampling for gold and multi-element geochemical analysis will follow immediately after the logging process. All samples will be prepared at ALS Laboratories’ facility in Cuiabá, Mato Grosso, and subsequently analyzed at the ALS analytical laboratory in Belo Horizonte, Minas Gerais.

“We’re encouraged by the geological consistency and strengthening alteration we’re seeing in our first two drill holes at Copeçal,” stated Rob Birmingham, President and CEO of GoldHaven Resources. “These early results support our interpretation of a large, structurally controlled system with the potential to host gold mineralization. With the drill now turning on our third hole, we look forward to expanding our understanding of the East Target and delivering steady news flow as we advance this exciting project.”

GoldHaven will continue to provide regular updates as drilling progresses and as assay results become available.

About the Copeçal Gold Project: A Brief History

The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s. GoldHaven’s tenements cover a total of 3,681 hectares in a geologically favourable setting within the Juruena Gold Province of Brazil.

The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining’s Tocantinzinho deposit. Additionally, the region hosts recently identified porphyry-style deposits (e.g., Serabi, Jaca) and epithermal-style deposits (e.g., X1, Aura). The presence of multiple deposit styles, along with the confirmation of large-scale gold deposits in the Juruena Province of Brazil, underscores the significant potential of the Copeçal Gold Project.

Recent exploration programs, including geochemical soil sampling, drone-mounted magnetometry surveys, and historical drilling data, indicate the presence of multiple gold-bearing structures. Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010 to 2016, including auger and air-core drilling, geophysical surveys, and rock geochemistry, identifying multiple zones of anomalous gold mineralization.

The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti’s exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential. Soil sampling grids and follow-up auger drilling in key areas revealed consistent gold values over wide zones, further supporting the presence of a substantial mineralized system.

VANCOUVER, British Columbia, Oct. 09, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (CSE: GOH | OTCQB: GHVNF | Frankfurt: 4QS) (“GoldHaven” or the “Company”) is pleased to announce that its inaugural diamond drilling program is underway at the Copeçal Gold Project in Mato Grosso State, Brazil. The first drill hole targeting the East Zone priority target is progressing well and is approaching its planned depth of 100 metres.

Initial geological observations from the first hole are highly encouraging. The hole has intersected approximately 30 metres of saprolite (deeply weathered rock) before entering strongly sheared and hydrothermally altered basement gneiss characterized by pervasive chlorite, sericite, and quartz alteration. This geological setting is consistent with the Company’s exploration model and supports the potential for a mineralized hydrothermal system at depth.

Highlights:

  • First drill hole has intersected approximately 30 metres of saprolite overlying strongly sheared and hydrothermally altered basement gneiss in the East Zone target
  • Alteration assemblage includes chlorite, sericite, and quartz – classic indicators of hydrothermal fluid activity associated with gold mineralization in orogenic and intrusion-related gold systems
  • Drilling contractor Ecodrill utilizing NQ-size diamond core (47.6mm diameter)
  • Total program: 1,200 metres planned across 5-6 angled holes testing both East and West Zone targets with holes up to 150 metres depth
  • Core samples being processed at ALS Global laboratories (sample preparation in Cuiabá, assays in Belo Horizonte)
  • Assay results expected in 4-6 weeks following completion of drilling and laboratory analysis
  • East Zone target defined by coincident gold and arsenic soil anomaly (>100 ppb Au) overlying interpreted structures identified through VLF electromagnetic and magnetic surveys

Figure 1: GoldHaven team begins drilling east target on Copeçal Gold project

The initial geological observations are highly encouraging and validate GoldHaven’s systematic exploration approach. The transition from thick saprolite into intensely sheared and altered gneiss at relatively shallow depths indicates that the drill hole has entered a structurally deformed and hydrothermally active zone – precisely the type of geological environment that hosts significant gold mineralization in orogenic and intrusion-related gold systems within the Juruena Gold Province.

The East Zone target area exhibits a robust gold and arsenic geochemical signature at surface, with soil values exceeding 100 ppb gold over a 3-kilometre strike length. This geochemical anomaly is coincident with interpreted structures – classic geological traps for gold deposition – identified through the Company’s VLF electromagnetic survey and historical geophysical data. The drilling program is designed to test whether the surface geochemical signature extends to depth and is associated with economic gold grades within the structurally-prepared host rocks.

“The start of our maiden drill program marks a transformational milestone for GoldHaven Resources,” said Rob Birmingham, President and CEO. “This moment is the result of systematic exploration, including a 107-hole auger program and ongoing VLF surveys that refined our targets and mapped structural controls. Early geological observations from COP-25-001 show strong deformation and alteration where saprolite meets basement rock—exactly what we hoped to see. While we await assay results, these features validate our targeting model and align with mineralized systems across the Juruena Gold Province. Supported by AngloGold Ashanti’s prior work and excellent infrastructure in Mato Grosso, we’re now advancing into the discovery phase and look forward to sharing results soon.”

GoldHaven Resources Corp. (” GoldHaven ” or the ” Company “) (CSE: GOH,OTC:GHVNF) (OTCQB: GHVNF) (FSE: 4QS) is pleased to provide an update on its exploration work program on its 100% owned Magno and Three Guardsmen Projects located in Northern British Columbia. The program was carried out by GoldHaven’s experienced technical team under the supervision of Jean Paulter P.Geo.

Highlights:

  • Magno and Three Guardsman successful completion of 2025 summer exploration programs, collecting 354 and 126 samples respectively.
  • Magno Project expanded by 5.159.13 hectares through strategic staking to secure coverage of the Cassiar Stock, believed to be related to mineralization.
  • Exploration at Magno has confirmed the presence of high-potential, structurally controlled skarn and CRD-style mineralization, drawing parallels to Coeur Mining Inc.’s Silvertip Project.
  • Three Guardsmen Project hosts high-grade Cu mineralization in epidote and magnetite skarns, with extensive malachite-stained pods extending over a 1 km strike, and geochemical pathfinders and textures suggesting a nearby intrusive source.

The field team has completed the 2025 exploration program, carrying out first-pass assessments at both the Magno Property and the Three Guardsmen. A total of 354 rock samples were collected at Magno, consisting primarily of grab samples along with chip and channel samples. At the Three Guardsmen, the team collected an additional 126 grab and chip samples, providing a solid foundation for advancing exploration on both properties.

 

Magno:

The Magno Project hosts multiple styles of mineralization that appear to share common fluid pathways and heat sources, indicating a series of related mineralizing events. During the two-week program at Magno, the team quickly recognized the significance of the Cassiar Stock — a 72 Ma Cretaceous granite mapped within the eastern margin of the Cassiar Batholith. Originally described by Panteleyev, detailed mapping by the team has confirmed a direct correlation between phases of the Cassiar Stock (biotite quartz monzonite porphyry) and the property’s mineralized showings. As a result, securing additional ground over the Cassiar Stock became an immediate priority, expanding the Magno Project to 35,732.66 hectares.

Figure 1: Magno project including staked extension located to the west

By consolidating the Cassiar Stock and its associated mineralized showings into a single claim package, GoldHaven’s technical team now has the rare advantage of interpreting the system as a whole rather than in isolated pieces. Even after limited fieldwork, the team has been able to connect mineralized skarns with north–south parallel contacts and crosscutting northeast-trending structures, where narrow apophyses of Cretaceous Cassiar Stock quartz monzonite intrude the surrounding Cassiar Terrane sediments.

Exploration at Magno Central (encompassing the Magno and D zones) has confirmed the presence of structurally controlled skarn and CRD-style mineralization within the Lower Cambrian Atan Group, specifically the Rosella Formation, which comprises limestone, marble, and clastic limestones. Historically, these zones have been well known for Ag-Pb-Zn mineralization; however, the team aims to expand on more recent discoveries indicating the presence of indium (In) and gallium (Ga). Comparisons can be drawn to Coeur Mining Inc.’s Silvertip Project, located within the same Cassiar Terrane north of the Magno property, which provides a strong analogue for the potential development of deeper, contact-parallel, skarn systems at Magno and D.

Mapping and sampling in the W (Tungsten showings) of the Kuhn & Dead goat Zones of the Magno property during the August field program focused on verifying historic trenches and conducting detailed mapping of both the prospective area and the mineralogical zonation of the skarns. Skarn mineral zonation is dominated by diopside–garnet assemblages, with additional zones containing tremolite, pyrrhotite, and scheelite.

Three Guardsmen:

The Three Guardsmen property comprises 14 contiguous mineral tenures covering 16,234 hectares within the Atlin Mining Division of northwestern British Columbia. The claims are 100% owned by GoldHaven Resources Corp.

Strategically located near Haines Junction, the Three Guardsmen Project sits in a highly prospective geological area known for copper-magnetite skarns with gold and molybdenum mineralization. Observed transitions from copper- and silver-rich zones to bismuth, tellurium, and gold-rich areas, along with molybdenum in altered granites, point to a possible nearby porphyry system.

At the Canadian Verdee and Mildred showings, high-grade copper occurs in concentrated pods dominated by chalcocite and bornite, with secondary chalcopyrite and widespread malachite staining. These mineralized zones, hosted in skarns, extend over a strike length of more than 1 km, highlighting the scale and potential of the system.

Situated within Late Cretaceous terranes known for world-class porphyry deposits such as Casino and Red Mountain, the project offers significant exploration potential. GoldHaven’s strategy leverages targeted geochemical and geophysical analysis to identify mineralized granitic intrusions which may be the source of the promising skarn mineralization observed at surface.

Next Steps:

The team will be looking to get assays back within 6-8 weeks and will begin the next phase of exploration through geochemical analysis, interpretation as well as continuing the large task of data compilation. Historically on Magno there exists data for nearly 11,000 meters of drill core across the property. The team has been continuing its efforts to digitize the data and plan to model all the historical work over the winter combined with its 2025 field work to plan for the next steps in exploration.

Rob Birmingham, CEO of GoldHaven Resources, commented: “We are extremely pleased with the successful completion of our 2025 summer exploration programs at Magno and Three Guardsmen. The team’s work has not only expanded the Magno Project by over 5,000 hectares to consolidate the Cassiar Stock but also confirmed the presence of high-potential skarn and CRD-style mineralization with strong analogues to Coeur Mining’s Silvertip Project.

Vancouver, British Columbia – (GlobeNewswire) – September 9th, 2025, GoldHaven Resources Corp. (“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce plans for immediate commencement of a maiden 1,200 m diamond drilling program targeting two priority gold targets at it’s Copeçal Gold Project in Mato Grosso, Brazil.

Highlights:

  • Recent auger drilling by GoldHaven and historical sampling (including by AngloGold Ashanti) identified strong gold in-soil anomalies at two priority targets: East and West.

  • Anomalies extend through up to 30m thick weathered saprolite profile, with surface geochemistry showing consistent gold values over wide zones, indicating potential bedrock sources.

  • VLF-EM surveys delineated resistivity and conductivity anomalies supporting the auger-defined gold targets.

  • Maiden 1,200 m diamond drilling program comprising 8-10 angled holes (max depth 150 m) to test unweathered bedrock at 80-120 m vertical depth below surface.

  • Drilling is scheduled to commence on or before October 1, 2025, and completed by end of November 2025.

Copeçal Gold Project Drill Targets:
GoldHaven has identified two high-priority drill targets, East and West, for its upcoming diamond drilling program. These targets were defined through a combination of strong gold anomalies from recent auger sampling and supportive geophysical VLF-EM resistivity and conductivity responses. Importantly, the targets are further reinforced by structural interpretations from historical high-resolution drone magnetics and surface geochemistry completed by previous operators, including Boa Gold Ltd. and AngloGold Ashanti Ltd. Together, these datasets highlight compelling opportunities for the identification of meaningful gold mineralization on the property. 

Figure 1: Copeçal Gold Project showing the Priority Targets (East and West) with the VLF-EM survey area, the High Resistivity Anomaly (> 1800 ohm*m – East), the High Conductivity Anomaly (< 250 ohm*m -West) relative to coincident surface and saprolite Au Geochemistry Anomalies (> 100 ppb Au – East and > 50 ppb Au – West).

East Target
The East Target is defined by a prominent high resistivity anomaly (> 1800 ohm*m) which is spatially coincided with strike consistent zones of gold geochemical anomalism (> 100 ppb Au) as highlighted by GoldHaven’s recent shallow auger drilling campaign and historical soil sampling.

 Drill targets have been defined by vectoring this surface and weathered zone gold anomalism through up to 30 m thick saprolite – weathered profile zone to a bedrock gold source extending to depth. Here, the highly resistive zone is interpreted to potentially represent alteration (silicification) of quartz mica schist associated with mineralization manifested along its sheared contact with granitic rocks.

West Target
Similarly, diamond drilling over the West Target will test depth extensions, associated with highly conductive VLF-EM responses (<500 ohm*m) and coincident with gold anomalous geochemistry (>50 ppb Au) manifested at surface and through up to 30 m thick saprolite – weathered profile as defined by historical auger drilling by AngloGold Ashanti. The highly conductive zone is interpreted to potentially represent sulphide mineralization associated with zones of shearing within and along contacts between granitic and schistose host rocks.

Figure 3: Copeçal Gold Project showing the West Target outline of the VLF-EM survey lines (in yellow), the location of the High Conductivity Anomaly (<250 ohm*m) relative to coincident surface and saprolite Au Geochemistry Anomalies (pink > 20 ppb Au, orange > 50 ppb Au).

Planned Diamond Drilling Program:
GoldHaven plans a maiden diamond drill program to test the two priority targets developed by its 2025 exploration activities at the Copeçal Gold Project.

To test the East and West Targets at Copeçal, GoldHaven has defined a 1,200 m diamond drilling program comprising 8 – 10 holes with a maximum drilled depth of 150 m. Angled holes are planned to intersect the projected target zones in unweathered bedrock at depths between 80 and 120 m vertically below surface.

A total 4 – 5 holes are planned at the East Target testing gold in soil and saprolite anomalism (> 100 ppb Au) over a strike distance of approximately 400 m coincident with a large area of high – resistivity (> 1800 ohm*m) as delineated by the VLF results.

The section line (yellow) shows the location of Figure 7.

Figure 7: Copeçal Project West Target vertical section facing northwest showing planned diamond drill hole traces targeting the High Conductivity Anomaly (< 250 ohm*m) and testing coincident surface and saprolite Au Geochemistry Anomalies (> 50 ppb Au) projected to depth.

Drilling is scheduled to commence on or before October 1st, 2025, and to be completed by the end of November 2025.

Rob Birmingham, CEO of GoldHaven Resources, commented: “We are thrilled to be moving forward with the maiden drill program at the Copeçal Gold Project, following the highly encouraging results from the combined data and interpretation of our auger drilling and VLF-EM survey. The East and West targets have delivered strong gold anomalies and represent exceptional opportunities for the identification of gold mineralization. Backed by the extensive historical work of AngloGold Ashanti and guided by Jon Hill, P.Geo, our team is positioned to unlock the full potential of this exciting gold project.”

About the Copeçal Gold Project: A Brief History
The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s. GoldHaven’s tenements cover a total of 3,681 hectares in a geologically favourable setting within the Juruena Gold Province of Brazil.

The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining’s Tocantinzinho deposit. Additionally, the region hosts recently identified porphyry-style deposits (e.g., Serabi, Jaca) and epithermal-style deposits (e.g., X1, Aura). The presence of multiple deposit styles, along with the confirmation of large-scale gold deposits in the Juruena Province of Brazil, underscores the significant potential of the Copeçal Gold Project.

Recent exploration programs, including geochemical soil sampling, drone-mounted magnetometry surveys, and historical drilling data, indicate the presence of multiple gold-bearing structures. Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010 to 2016, including auger and air-core drilling, geophysical surveys, and rock geochemistry, identifying multiple zones of anomalous gold mineralization.

The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti’s exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential. Soil sampling grids and follow-up auger drilling in key areas revealed consistent gold values over wide zones, further supporting the presence of a substantial mineralized system.

VANCOUVER, British Columbia, Sept. 04, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to provide an update on its exploration work program on the 100% owned Magno Project located in Northern British Columbia.

Highlights

  • The Magno Project field program is halfway complete, with systematic sampling and detailed mapping advancing understanding of larger, deeper targets linked to Cretaceous magmatism and extensive surface skarn mineralization.
  • The project features multiple mineralization styles sharing common fluid pathways, enabling a holistic interpretation of the consolidated Cassiar Stock system, including connections between mineralized skarns and intrusive structures.
  • At the Magno and D zones, structurally controlled skarn and CRD-style mineralization with high-grade Ag-Pb-Zn (exceeding 2,000 ppm Ag) has been confirmed, alongside emerging indium and gallium potential, drawing similarities to Coeur Mining’s Silvertip Project.
  • Mapping at the Kuhn and Dead Goat zones has delineated skarn horizons with potential for up to 2 km strike extensions, featuring diopside-garnet assemblages, scheelite, and crosscutting structures indicating broader exploration upside.

Magno Summer 2025 Field Program

GoldHaven’s fully funded 2025 exploration program has passed the halfway mark, with the team making strong progress through systematic sampling and detailed structural and mineralization mapping. The program is designed to advance the Company’s understanding of the potential for larger and deeper targets linked to the Cretaceous magmatism, while also evaluating the extensive surface skarn and carbonate replacement-style mineralization across the project. Initial samples are being prepared for shipment to ALS Global in Whitehorse, Yukon. The results are expected to provide important catalysts and direction for advancing the Magno Project.

The Magno Project hosts multiple styles of mineralization that appear to share common fluid pathways and heat sources, reflecting a series of related mineralizing events. By consolidating the Cassiar Stock and its associated mineralized showings into a single claim package, GoldHaven’s technical team now has the rare advantage of interpreting the system as a whole rather than in isolated pieces. Even after limited fieldwork, the team has been able to connect mineralized skarns with north–south parallel contacts and crosscutting northeast-trending structures, where narrow apophyses of Cretaceous age Cassiar Stock intrude the surrounding Cassiar Terrane sediments.

A portion of the team’s work has been directed toward confirmation sampling, including high-grade surface samples along with historic trench and chip sample intercepts. These efforts were further advanced through the addition of new extensions to historic chip and channel samples, concentrated in areas of known mineralization such as the Magno and Kuhn zones, where historical resource estimates have been reported by previous operators.

Magno and D Zones

Exploration at Magno Central (encompassing the Magno and D zones) has confirmed the presence of structurally controlled skarn and CRD-style mineralization as well as some unique and poorly exposed hydrothermal mineralization within the Lower Cambrian Atan Group, specifically the Rosella Formation, which comprises limestone, marble, and clastic limestones. Historically, these zones have been well known for Ag-Pb-Zn mineralization; however, the team aims to expand on more recent discoveries indicating the presence of indium (In) and gallium (Ga). Mineralization is characterized by sulphur-rich, redox-driven skarns hosting massive galena with associated sphalerite and magnetite. Both historical sampling and recent sampling by James Turner P.Geo has verified high silver values from these structurally controlled skarns exceeding 2,000 ppm Ag from galena-dominated zones.

Figure 1: Large galena ore sample found within the Magno Zone (2025 Summer Field Program)

At both the Magno zones, mineralization is structurally controlled, occurring as bedding-parallel, conformable “manto” bodies as well as crosscutting “chimney”-style mineralization, with an overall northeast trend cutting through the Rosella Group limestones. Comparisons can be drawn to Coeur Mining Inc.’s Silvertip Project, located within the same Cassiar Terrane north of the Magno property, which provides a strong analogue for the potential development of deeper, contact-parallel, large-scale skarn systems at Magno. The D zone uniquely shares analogies with the Magno but additionally contains some impressive zones of massive sulphides which carry textural similarities to hydrothermal mineralization. More work is required to understand the D zone in greater detail, but its presence suggests a larger, longer-lasting, multiphase and potentially multi-deposit style district within Magno than previously imagined.

Kuhn and Dead Goat:

Mapping and sampling in the Kuhn Zone during the August field program focused on verifying historic trenches and conducting detailed mapping of both the prospective area and the mineralogical zonation of the skarns. Two principal skarn horizons, the Lower and Upper 3a skarns, have been delineated, traced for 640 m and 206 m respectively, with the potential to extend along strike for up to 2 km each. The Lower 3a skarn, generally well exposed, follows the Boya–Rosella Group contact, while the Upper 3a skarn lies 10–20 m stratigraphically above and is more poorly exposed.

Skarn mineral zonation is dominated by diopside–garnet assemblages, with additional zones containing tremolite, pyrrhotite, and scheelite. The skarns pinch and swell along strike, with variable widths. Historical reports document scheelite mineralization in zones 1–4 m wide; however, visible scheelite has also been observed in quartzites adjacent to the contact, suggesting potential for increased widths and further exploration upside.

At Kuhn South, the same skarn horizons are present but are crosscut by a northeast-trending structure. Here, skarn mineralization is oriented NE, characterized by a silicified diopside–garnet core with pervasive sphalerite banding.

Similar mineralization is present at the Dead Goat showing, a north–south striking skarn composed of diopside, garnet, pyrrhotite, and scheelite, ranging from 1 m to several m in width, with a surface expression of up to 200 m.

VANCOUVER, British Columbia, Aug. 21, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce it has mobilized its geological team and has begun its exploration efforts across the 100%-owned Magno and Three Guardsman projects, located in Northern British Columbia.

GoldHaven’s fully funded 2025 exploration program is set to advance its highly prospective assets, the Magno and Three Guardsman projects. At the Magno Project, systematic sampling and structural mapping will target skarn and replacement-style mineralization with the goal of vectoring toward a potential porphyry source linked to the Cassiar Batholith. Meanwhile, at the Three Guardsmen Project, the team will build on 2024 results that outlined classic porphyry-style alteration zonation within granitic units—considered strong supporting evidence for the existence of a large-scale mineralized system at depth. Together, these programs provide multiple opportunities to further develop and expand the projects knowledge leading towards our goal of a 2026 drill campaign.

Magno Project

The Company holds 100% ownership of the Magno mineral claims in British Columbia. The Project spans 30,573.53 hectares and is situated within the historically rich Liard Mining Division. The Project is accessible via Highway 37, which crosses the southeastern claim area, providing good access for future exploration and development work.

The Magno Project hosts several critical metals, including tin (Sn), indium (In), zinc (Zn), silver (Ag) gold (Au), tungsten (W), and gallium (Ga) which are essential for various industries, including electronics, defense, batteries, and green energy technologies. Additionally, the Project hosts several different styles of base metal (zinc-lead) mineralization, including skarn and carbonate replacement styles along with potential for deeper porphyry-associated copper-molybdenum-tin mineralization. GoldHaven is looking to apply new geological research to potentially overlooked areas to analyze a broad range of metals and use as vectors to potential porphyry mineralization.

Magno Exploration Program:

GoldHaven will field a ten-person geological team for its 2025 program, based in a fully serviced multi-room facility in the Cassiar area, providing close access to the Project. Working in two-person crews, the team will systematically cover the more than 30-kilometre north–south strike length of the Cassiar Terrane. The program is designed to identify and sample widespread skarn and replacement-style mineralization, with a particular focus on geochemical zonation and mappable geothermal gradients that may provide vectors toward deeper mineralizing systems.

The Cassiar Terrane hosts several of the Magno property’s key mineralized showings, where sampling has returned significant values including 110 to 1,749 ppm tin and up to 5.58% zinc (Johnston, 2024). Historical work by Eveready (2003) further highlighted the property’s potential, reporting grades of 6.2% Zn, 28.2% Pb and 820 g/t Ag over 1.2 metres. Priority exploration areas include the Magno, Middle and Upper D, Kuhn, and Dead Goat zones. Geologically, the Cassiar Terrane overlies the Cretaceous-age Cassiar Batholith—a biotite- and hornblende-bearing granite intrusive interpreted as a potential driver for the region’s mineralizing fluids.

This work will provide two major benefits. First, it will advance GoldHaven’s understanding of the distribution and genesis of critical metals such as indium, gallium, and germanium, along with silver, zinc, and lead replacement-style targets within the Cassiar Terrane. The presence and zonation of these metals within skarn systems are often directly linked to the larger magmatic-hydrothermal processes responsible for porphyry development. Second, the resulting geochemical data will help refine and prioritize targets for future geophysical surveys—vectoring exploration toward porphyry-style mineralization within the Cassiar Batholith, where the ultimate prize is the discovery of a gold- and copper-rich system at depth.

Data generated from this geochemical program, when integrated with detailed structural mapping, will support vectoring toward potential fluid pathways emanating from the Cassiar Batholith—which may host a buried porphyry system.

The Guardsmen Project sits within a geologically prospective terrane known to host copper- and gold-bearing skarn mineralization, as well as polymetallic systems. Historical exploration across the property has identified copper, gold, silver, molybdenum, zinc, and magnetite mineralization across multiple showings. Notably, transitions from Cu/Ag-rich zones to Bi/Te/Au-rich domains suggest analogues to Hedley-style skarns, with potential for distal, gold-enriched systems—key exploration targets moving forward.

The project is situated within Late Cretaceous terrane known to host significant porphyry deposits such as Casino and Red Mountain. GoldHaven’s exploration strategy focuses on geochemical and geophysical surveys aimed at identifying granitic intrusions that may represent the porphyry sources associated with the skarn mineralization observed at surface.

Three Guardsman Exploration Program:

Following the completion of the 2–3-week Magno field program, GoldHaven’s exploration team will mobilize through Whitehorse on route to the Three Guardsmen Project, where a 10-day exploration campaign is planned.

The team will build on the 2024 exploration work at the Three Guardsmen Project, which included localized geological mapping and systematic rock sampling on a grid. That program successfully identified classic porphyry-style alteration zonation—particularly within the granitic units underlying mineralized skarn horizons. These patterns are considered strong indicators of a potential porphyry source at depth.

Drawing on techniques and insights developed during the establishment of the Magno program, the team aims to expand mapping efforts across the Three Guardsmen property, with a focus on further delineating propylitic, phyllic, and potassic alteration zones identified in the previous season. This integrated approach will help refine priority target areas for future drilling.

GoldHaven’s technical team will be advancing the Three Guardsmen Project toward the first phase of systematic exploration, focused on testing these high-priority porphyry and skarn targets. Alongside Magno, the project is positioning itself as a compelling and underexplored opportunity in the search for critical, strategic and base metals.

“We are excited to launch our summer work programs at the Magno and Three Guardsman Projects in northern British Columbia—two highly prospective assets in our portfolio. Leveraging results from prior exploration and the recently completed comprehensive data compilation over both projects, our technical team has targeted key areas of focus with strong mineralization potential. The program will be led in the field by Company Director Gerry Diakow, with Michael Garagan serving as Technical Lead, and Jean Pautler as P. Geo to ensure disciplined execution and geological oversight throughout the campaign” – Rob Birmingham, CEO of GoldHaven Resources Corp.

Figure 1: Magno property with BC regional geology highlighting historical work and present showings

The Magno Project hosts several critical metals, including tin (Tn), indium (In), zinc (Zn), silver (Ag) gold (Au), tungsten (W), and gallium (Ga) which are essential for various industries, including electronics, defense, batteries, and green energy technologies. Additionally, the Project hosts several different styles of base metal (zinc-lead) mineralization, including skarn and carbonate replacement styles along with potential for deeper porphyry-associated copper-molybdenum-tin mineralization. GoldHaven is looking to apply new geological research to potentially overlooked areas to analyze a broad range of these critical and strategic metals to vector in on potential porphyry mineralization.

Critical Metals at Magno: A Strategic Opportunity

Data from the Magno historical workings highlight the potential for significant concentrations of technology-critical metals in addition to the established base and precious metal potential. As global industries face supply shortages of indium, tin, gallium, tungsten and strategic base metals like zinc, Magno presents an attractive opportunity in a geopolitically stable and mining-friendly jurisdiction of Canada.

The Project covers the contact zone between the mid-Cretaceous-aged Cassiar Batholith and the late Proterozoic to late Paleozoic carbonate and clastic sedimentary rocks of the Cassiar Terrane. Base metal (zinc-lead) rich skarn and carbonate replacement mineralization, often associated with significant silver values, are widespread in the region, including on the Project. Additional historical insight identified, geochemically anomalous molybdenum (Mo), ± copper (Cu), tin and tungsten values associated with Late Cretaceous intrusions, including the 7 by 30 km Cassiar or Troutline Creek stock, which intrude the Cassiar Terrane proximal to the Cassiar Batholith. The mineralized granitic intrusions may also be the source of the skarn and carbonate replacement mineralization in the intruded sedimentary sequence.

In addition to the historical Zn-Pb-Ag and Cu-Mo mineralization, reconnaissance sampling by Johnston (2024) indicates anomalous indium and additional support for tin as potential critical metal additions. Recent research published on skarn deposits in SE China (Tan, 2024) suggests that variations in the indium/zinc ratios in skarn environments may provide a vector towards the causative source intrusion(s) and possible associated Cu-Mo+/-Sn-W mineralization. Johnston took six confirmatory samples which returned indium values ranging from 1.1 to 63.8 ppm, with three of the six samples greater than 40 ppm. Additionally, a verified sample from the Kuhn showing taken in 2019 by Fundamental Resources (AR 38356) contained 85.20 ppm indium, suggesting potential of the Cassiar Terrane to yield indium mineralization. Tin and zinc values were significant ranging from 110 to 1749 ppm tin and up to 5.58% zinc in Johnston’s samples.

This research directly supports the exploration model at Magno, where high indium values in the skarns could indicate proximity to deeper, potentially undiscovered Cu-Mo porphyry bodies. This growing body of evidence reinforces the strategic significance of the Property, not only for traditional base and precious metals but also for critical metals. Gallium and germanium are additional critical metals that may be present on the property and will be a focus for future work.

This field season, GoldHaven will look to explore the skarns with detailed geochemical analysis of Ag, Zn, Sn, In, W and Ga and correlate this data to the magmatic source of mineralization in the granites. With Mo porphyries already known to be present in the region, the Company believes the potential of locating Mo-Cu porphyry mineralization on the Magno property is very high.

Tin (Sn): A Critical Metal for Electronics & Battery Storage

Tin is an essential component of electronic circuits, lithium-ion batteries, and soldering materials, with increasing demand due to the electrification of transportation and grid storage solutions.

  • Magno Project Key Grades Identified: 5,200 ppm Sn (Middle D Zone, Eveready 2002)5,199 ppm Sn (Pant N Zone, Eveready 2003)2,097 ppm Sn (Magno North, Eveready 2003)1,749 ppm Sn (Middle D, Johnston 2023)​

Tin, a critical metal for electronics & battery storage, is an essential component of electronic circuits, lithium-ion batteries, and soldering materials, with increasing demand due to the electrification of transportation and grid storage solutions.

In 1978, sampling by the BC Department of Mines identified anomalous tin values on the current property. Follow-up sampling of old CCS drill core by Shell Canada in 1979 returned several anomalous tin intercepts, mainly from the Middle D Zone ranging up to 6.5% Sn over 0.9 metres. The results of samples which returned greater than 1000 ppm Sn are presented in Table 2.

Table 1: Anomalous Tin Results from the Magno Property (see Magno 43-101 filed on SEDAR+)

*This work was carried out prior to the introduction of NI 43-101 and the results have not been verified by a Qualified Person, except for the samplings by Johnston and Eveready, and hence cannot be relied upon. However, the company believes the results presented suggest the possibility of previously unrecognized tin mineralization on the property. Verifying this potential will be one of the objectives of the 2025 summer work program.

Indium (In): A High-Tech & Green Energy Essential

Indium is a critical metal for semiconductors, solar panels and LCD displays primarily recovered as a byproduct of zinc mining and smelting. Reconnaissance sampling on the Magno Project combined with recent confirmatory sampling by Johnston, a Qualified Person, suggests potential for significant quantities of indium associated with the known zinc mineralization. Three of six samples collected by Johnston from the Magno Project for confirmation returned indium values exceeding 40 ppm In, all ranging from 1.2 to 63.8 ppm In.
Indium is indispensable to modern technology, as it is a key component of indium-tin oxide (ITO), the transparent conducting film used in virtually all flat-panel displays and touchscreens. Its unique combination of transparency, electrical conductivity, and strong adherence to glass makes it irreplaceable for applications in smartphones, tablets, televisions, and high-tech architectural glass coatings. With 65% of global indium consumption driven by electronic displays, demand continues to rise.

Recognizing its strategic importance, indium is included on the Canadian Geological Survey’s list of 34 critical minerals. The United States is entirely reliant on imports to meet its indium demand, consuming 170 metric tons in 2018 from sources such as China (27%), Canada (22%), South Korea (11%), and Taiwan (10%).

Zinc (Zn): A Base Metal with Green Energy Potential

Zinc is an essential industrial metal, used in galvanisation, batteries and green energy technologies. The Magno Property hosts widespread zinc mineralization with associated lead and silver values in several different geological settings.

  • Magno Project Key Grades Identified: 41% Zn (Magno South, Eveready 2004)6.2% Zn, 28.2% Pb, 820 g/t Ag over 1.2m (Magno North, Eveready 2003)16% Zn, 1.3% Pb, 19.3 g/t Ag, 0.9 g/t Au over 4.3m (Magno North, Eveready 2003)7.4% Zn, 14.2% Pb, 398 g/t Ag (Upper D Zone, Eveready 2002)

Historic work from at least the 1960s onwards has mainly focussed on the zinc-lead-silver potential of the known carbonate replacement deposits, particularly the Middle D and Magno deposits.

Several historic reserves/resources have been defined, but since all pre-date the introduction of NI 43-101 and the work was not carried out under the supervision of a Qualified Person, these results cannot be relied upon. They do however provide a starting point for new exploration using updated geological knowledge, improved deposit models and modern geophysical and geochemical techniques and interpretations. Limited recent sampling carried out by Johnston, who is a Qualified Person, confirmed the widespread nature of zinc mineralization on the property. Of the six samples he collected, four exceeded 0.5% Zn with a maximum of 5.58% Zn.

Silver (Ag): Indispensable Metal in Modern Industry

Silver continues to play a critical role across a wide range of industrial applications. Today, it is essential in the production of solder and brazing alloys, batteries, dental materials, glass coatings, LED chips, medical devices, nuclear technology, photography, solar (photovoltaic) energy, RFID chips used for global shipment tracking, semiconductors, touch screens, water purification systems, wood preservatives, and numerous other technologies.
The Washington-based Silver Institute aptly refers to silver as “the indispensable metal,” highlighting its widespread utility.

Over the past decade, leading industrial consumers of silver have included the United States, Canada, China, India, Japan, South Korea, Germany, and Russia. While demand from traditional sectors has declined, it has been offset by increasing use in emerging and advanced technologies, underscoring silver’s enduring importance in the global economy.

The Magno Property continues to exhibit strong potential for high-grade silver, along with associated lead and zinc within replacement skarn systems, historical exploration targets that, despite their promise, were never advanced into a NI 43-101 compliant resource. Recent sampling has confirmed significant silver grades which reinforce the high-grade nature typical of this deposit style. While these results are compelling, they represent only one aspect of a broader geological picture. GoldHaven’s exploration strategy remains focused on a larger-scale opportunity, using these mineralized showings and newly collected data to guide the search for a potential buried porphyry system within the region.

Tungsten (W): Resurgence as Prime Military Metal

Tungsten has emerged as a critical mineral of strategic importance due to its unmatched physical properties and indispensable role in high-performance applications. With the highest melting point of any metal and exceptional density and hardness, tungsten is essential to modern defense systems, including armor-piercing munitions, kinetic energy penetrators, and aircraft turbine components. Its resilience to extreme temperatures and wear makes it equally vital in aerospace, advanced manufacturing, and nuclear energy. These characteristics, combined with a lack of viable substitutes, position tungsten as a cornerstone of national security and industrial competitiveness.

The Kuhn and Dead Goat showings which correlate to GoldHaven’s unverified inferred resource is reflective of Skarn replacement of tungsten, molybdenum and minor copper. This area much like the Ag, Pb, Zn replacements are situated with the Cambrian stratigraphy of the Cassiar terrane. The Atan Group limestones, marbles and calcareous sedimentary rocks character of this group provide the best lithological host for such a deposit style. Below, verified surface samples are expressive of the grades which made up the inferred resource in the area. GoldHaven will be looking into verifying these results and more in the coming weeks during the field program.

Magno Project Key Grades Identified:

  • Historic drilling by Shell Canada included 17 diamond drill holes totaling 1,766 metres, confirming the presence of high-grade scheelite (CaWO4) and molybdenite (MoS₂).
  • Recent exploration has confirmed significant tungsten and molybdenum mineralization in metasomatic skarn lenses
  • Hosts a historic resource of 409,300 tonnes at 0.48% WO₃ (tungsten trioxide) and 0.134% MoS₂ (molybdenum disulfide) in the Kuhn North zone

This work was completed prior to the implementation of NI 43-101 standards, and the results have not been confirmed by work conducted under the supervision of a QP. The 2025 summer work program will aim to verify this potential.

Gallium (Ga): Untapped Potential in High-Tech Metals

Gallium is a strategic metal used in fiber optics, 5G networks, and advanced semiconductors. While historical exploration did not target these elements specifically, Magno’s CRD deposits may host economically significant concentrations of this critical metal. GoldHaven plans to evaluate this potential further as part of its upcoming exploration programs.

These metals are key to modern electronics and defense applications, positioning Magno as an emerging target for high-tech metal exploration.

“The confirmation of high-grade tin, zinc, and tungsten, and the potential for anomalous indium and gallium at the Magno Project represents a major step forward for GoldHaven Resources. These critical metals are integral to the identification of significant mineralization across the property and the goal of supporting the global clean energy transition and high-tech industries, positioning Magno as a strategically important asset. Our recent compilation work has also revealed impressive historical assays of high-grade silver and gold, further strengthening the project’s polymetallic foundation. With exploration accelerating in both British Columbia and Brazil in the second half of the year, we are well-positioned to advance Magno’s potential and create long-term growth for our shareholders.” – Rob Birmingham, CEO of GoldHaven Resources Corp.

VANCOUVER, British Columbia, Aug. 07, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (“GoldHaven” or the “Company“) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce, further to its news release dated May 16, 2025, the refiling of an independent technical report for its Copeçal Project prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects. The technical report, titled “Technical Report on the Geology, Mineralization and Exploration of the Copeçal Gold Project, Mato Grosso State, Northwestern Brazil” and with an effective date of May 29, 2025 can be found on the Company’s SEDAR+ profile at www.sedarplus.ca and on the Company’s website here.

Key Highlights:

Strategically Located in Tier-One Mining Jurisdiction

The Copeçal Gold Project spans 3,681.76 hectares across two contiguous exploration permits in northern Mato Grosso, Brazil. The property benefits from inclusion in the “Legal Amazonia” zone, offering tax incentives and access to robust infrastructure. The site is within 60 km of Alta Floresta, a regional hub with daily commercial flights and established mining services and is connected via well-maintained roadways and hydroelectric power. These attributes provide a solid foundation for cost-effective exploration and future development.

100% Ownership Through Recent Strategic Acquisition

In January 2025, GoldHaven acquired the Copeçal Project via a three-cornered amalgamation with Boa Gold Corp., consolidating full ownership of the mineral rights through its Brazilian subsidiary, Ouro Resources Do Brasil Ltda. The acquisition included two key exploration permits originally explored by AngloGold Ashanti, securing GoldHaven’s position in one of Brazil’s most prospective gold belts.

Geological Setting Favourable for Orogenic Gold Systems

The Copeçal Project is situated within the Juruena Magmatic Arc, a Paleoproterozoic geological structure that has historically yielded significant gold discoveries. The property is hosted in a 20 km-wide sinistral shear corridor—a structural setting strongly associated with orogenic gold deposits. Ground magnetometry and soil geochemistry confirm the presence of multiple shear-related gold-bearing structures, indicating strong potential for mesozonal, shear zone-hosted mineralization.

Historic Exploration by AngloGold Ashanti Defines Key Targets

Between 2010 and 2016, AngloGold Ashanti conducted extensive early-stage exploration, including soil and stream sediment geochemistry, auger and air core drilling, and ground geophysical surveys. This work identified two major soil anomalies and a cluster of 13 auger drill holes with consistent gold values exceeding 15 ppb Au—interpreted as indicators of primary mineralization. Despite encouraging results, follow-up was limited, leaving significant upside potential for further discovery.

Path Forward: Defined Targets and Efficient Exploration Strategy

GoldHaven is in the process of refining exploration targets through additional drone magnetometry and auger drilling. The SW-I, SW-II, and SW-III auger clusters represent priority drill targets, with structural and geochemical alignment supporting potential for gold mineralization. A two-phase exploration program was recommended, beginning with soil and auger infill sampling and shallow drilling. Following the completion of the drone geophysical survey and auger sample assay interpretation the Company will prepare for its maiden drill program.

Auger Drill Program Samples Received

The 1,325 samples, including QAQC samples, collected from the 2,153m Auger Drill program at the Copeçal Gold project have been received by ALS Global Laboratories. Assay results are expected to be reported in late July or early August.

The Auger drill program included 92 Auger holes which systematically covered the main area of the east anomaly on a 100m x 50m grid while a further 15 reconnaissance holes targeting geochemical – structural targets projected towards the south-east from the western anomaly. Holes were drilled from surface to the weathered rock (regolith) – fresh rock interface or to a maximum depth of 30m. The average hole depth was 20.13 meters with the hole depth range of 2m – 30m.

About the Copeçal Gold Project: A Brief History

The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s. GoldHaven’s tenements cover a total of 3,681 hectares in a geologically favorable setting within the Juruena Gold Province of Brazil.

The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining’s Tocantinzinho deposit. Additionally, the region hosts recently identified porphyry-style deposits (e.g., Serabi, Jaca) and epithermal-style deposits (e.g., X1, Aura). The presence of multiple deposit styles, along with the confirmation of large-scale gold deposits in the Juruena Province of Brazil, underscores the significant potential of the Copeçal Gold Project.

Recent exploration programs, including geochemical soil sampling, drone-mounted magnetometry surveys, and historical drilling data, indicate the presence of multiple gold-bearing structures. Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010 to 2016, including auger and air-core drilling, geophysical surveys, and rock geochemistry, identifying multiple zones of anomalous gold mineralization.

The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti’s exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential. Soil sampling grids and follow-up auger drilling in key areas revealed consistent gold values over wide zones, further supporting the presence of a substantial mineralized system.

VANCOUVER, British Columbia, July 08, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce completion of its initial Auger drill program at the Copeçal Project, Brazil which commenced on June 9th, 2025. A total of 107 auger holes were successfully drilled, delivering 2,153.4 metres of subsurface coverage and marking a significant milestone in exploration efforts.

The Auger drill program included 92 Auger holes which systematically covered the main area of the east anomaly on a 100m x 50m grid while a further 15 reconnaissance holes targeting geochemical – structural targets projected towards the south-east from the western anomaly. Holes were drilled from surface to the weathered rock (regolith) – fresh rock interface or to a maximum depth of 30m. The average hole depth was 20.13 meters with the hole depth range of 2m – 30m.

Figure 2: Auger Drilling program completed 92 Auger holes which systematically covered the main area of the east anomaly on a 100m x 50m grid

A total of 1,325 samples, including QAQC samples, have been shipped to ALS Global Laboratories for analysis. Sample preparation is being undertaken at ALS’s facility in Cuiabá, Brazil, with final low detection fire assay analysis completed via their laboratory in Belo Horizonte, Brazil. To ensure rigorous QA/QC protocols, sampling was conducted at consistent 2-metre intervals down the drill hole. Quality control samples—including blanks, certified standards, and duplicates—were inserted at a rate of 10% of the total sample batch. These QA/QC measures adhere to industry best practices and align with the quality assurance standards of ALS Global Laboratories. Assay results are expected to be reported in late July or early August.

Samples from the Auger program, which included soil – saprolite and remnant rock fragments were geologically logged to inform the ongoing preparation of a 3D geological – lithogeochemical model for the East Anomaly. Initial observations suggests that areas where the depth to bedrock exceeds 20m reflect a more pronounced, deeper regolith profile developed over potentially mineralized and hydrothermally altered areas where the bedrock granite gneiss and schist has been more highly sheared and preferentially weathered. These observations are supported by the presence of sericite alteration coincident with disseminated limonitic boxwork (after pyrite) logged in samples collected from a number of the deeper Auger holes.

Rob Birmingham, CEO of GoldHaven Resources, commented: “We are pleased to announce the successful completion of our auger drilling program at the Copeçal Gold Project, with a total of 2,153.40 meters drilled. All assay samples have been shipped for analysis. While our initial efforts were focused on the east target, we are particularly encouraged to have concluded the program by drilling the more prominent anomaly on the west target. Our attention now turns to the upcoming Very Low Frequency (VLF) electromagnetic geophysical survey, expected to commence mid-month, which will enhance our understanding of the structures within the east and west targets, as well as highlight additional prospective zones across the property.”

VLF-EM Survey Overview

Looking ahead, GoldHaven anticipates launching a Drone-borne Very Low Frequency (VLF) Electromagnetic Survey in July (referred to in Figure 4). This survey will target the structural trends believed to be favorable hosts for gold mineralization, covering both the East and West Gold-in-Soil anomalies as well as their potential strike extensions. The integration of VLF-EM geophysics with auger geochemistry will provide a robust framework for finalizing diamond drill collar locations, thereby maximizing the efficiency and effectiveness of future drilling campaigns

VANCOUVER, British Columbia, June 26, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to provide an update on its systematic auger drill program over the east and west anomalies initiated on June 9th, 2025. The Company’s geological team has successfully drilled past the half-way mark and the first round of assays have been shipped to ALS Global Laboratory, with sample preparation being completed in Cuiaba, and sample analysis being finalized in Belo Horizonte.

GoldHaven has now reached 70% of the planned program, successfully completing 1,400 meters and has intersected regolith, weathering profile consistent with expectations at 0-20 meters depth. Additionally, several holes show weathering down to 30 meters in vertical depth which may indicate preferential weathering along the major structures being targeted for potential mineralization.

GoldHaven has submitted a total of 350 samples from the East Target of its Copeçal Project to ALS Global Laboratories for analysis. To ensure rigorous QA/QC protocols, sampling was conducted at consistent 2-metre intervals down the drill hole. Quality control samples—including blanks, certified standards, and duplicates—were inserted at a rate of 10% of the total sample batch. These QA/QC measures adhere to industry best practices and align with the quality assurance standards of ALS Global Laboratories. Assay results are expected within approximately 3 to 4 weeks.

Rob Birmingham, CEO of GoldHaven Resources, commented: “We are excited to have surpassed the first half of auger drilling on our Copeçal Gold project, with our first round of assays shipped for analysis. The initial work has been focused on our east target, while we anticipate shifting to the west target in the coming days which will give us more clarity on the anomalies prior to the initiation of diamond drilling.”

Auger Drilling and Electromagnetic VLF Survey Overview

The Auger Drilling Program is focused primarily on defining a 3D litho-geochemical footprint of gold distribution within the regolith profile beneath the extensive East Gold-in-Soil Anomaly. Vertical auger holes are being drilled systematically from surface to the regolith-bedrock interface—expected range is 5 to 30m in depth—on a tight 100m x 50m grid. This methodical approach is expected to generate high-resolution data critical for the refinement of subsurface geological and structural models.

Looking ahead, GoldHaven anticipates launching a Drone-borne Very Low Frequency (VLF) Electromagnetic Survey in July (referred to in Figure 2). This survey will target the structural trends believed to be favourable hosts to gold mineralization, covering both the East and West Gold-in-Soil anomalies as well as their potential strike extensions. The integration of VLF geophysics with auger geochemistry will provide a robust framework for finalizing diamond drill collar locations, thereby maximizing the efficiency and effectiveness of future drilling campaigns

About the Copeçal Gold Project: A Brief History

The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s. GoldHaven’s tenements cover a total of 3,681 hectares in a geologically favourable setting within the Juruena Gold Province of Brazil.

The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining’s Tocantinzinho deposit. Additionally, the region hosts recently identified porphyry-style deposits (e.g., Serabi, Jaca) and epithermal-style deposits (e.g., X1, Aura). The presence of multiple deposit styles, along with the confirmation of large-scale gold deposits in the Juruena Province of Brazil, underscores the significant potential of the Copeçal Gold Project.

Recent exploration programs, including geochemical soil sampling, drone-mounted magnetometry surveys, and historical drilling data, indicate the presence of multiple gold-bearing structures. Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010 to 2016, including auger and air-core drilling, geophysical surveys, and rock geochemistry, identifying multiple zones of anomalous gold mineralization.

The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti’s exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential. Soil sampling grids and follow-up auger drilling in key areas revealed consistent gold values over wide zones, further supporting the presence of a substantial mineralized system.

VANCOUVER, British Columbia, June 17, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (“GoldHaven” or the “Company”) (CSE: GOH | OTCQB: GHVNF | FSE: 4QS) is pleased to announce that it has entered into an agreement to acquire the Kuhn, Dead Goat, and M3 claims (the “Claims”) located in northwestern British Columbia, within the Company’s flagship Magno Project. The claims total 1,100.6 acres and host a historic resource of 409,300 tonnes at 0.48% WO₃ (tungsten trioxide) and 0.134% MoS₂ (molybdenum disulfide) in the Kuhn North zone. These estimates are historical in nature and do not meet NI 43-101 standards and therefore should not be relied upon.

Tungsten: A Critical Mineral of Strategic Importance to North America

Tungsten has emerged as a critical mineral of strategic importance due to its unmatched physical properties and indispensable role in high-performance applications. With the highest melting point of any metal and exceptional density and hardness, tungsten is essential to modern defense systems, including armor-piercing munitions, kinetic energy penetrators, and aircraft turbine components. Its resilience to extreme temperatures and wear makes it equally vital in aerospace, advanced manufacturing, and nuclear energy. These characteristics, combined with a lack of viable substitutes, position tungsten as a cornerstone of national security and industrial competitiveness.

However, the global tungsten supply chain faces a significant geopolitical risk. China, which controls over 80% of global tungsten production and refining, enacted strict export controls in February 2025 that have effectively halted shipments of key tungsten products. Though not an outright ban, China has issued no export licenses under the new regime, creating a de facto blockade that has shocked global markets and driven to increased prices and supply uncertainty. This move highlights the urgent need for diversified, secure tungsten supply chains as Western nations confront the strategic vulnerabilities of relying on a single dominant supplier for such a critical resource. Analysts anticipate that Chinese-supplied tungsten may be scarce in the global markets driving companies and countries to explore for alternative sources and strategies to mitigate the impact of China’s export controls.

Acquisition Highlights:

  • The Kuhn and Dead Goat properties are in the Cassiar Mining District, British Columbia, and have been explored since at least the 1970s.
  • Historic drilling by Shell Canada included 17 diamond drill holes totaling 1,766 metres, confirming the presence of high-grade scheelite (CaWO4) and molybdenite (MoS₂).
  • Well-developed skarn-type mineralization system.
  • Recent exploration has confirmed significant tungsten and molybdenum mineralization in metasomatic skarn lenses, with ongoing potential for resource expansion.
  • Historical Resource Estimates:

Historical Estimate Disclosure: This resource estimate constitutes a “historical estimate”, as that term is defined in National Instrument 43-101 Disclosure Standards for Mineral Projects (“NI 43-101”). This information is derived from summary report McDame project 82-546-10512, filed by Shell Canada Resources. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves, and accordingly the estimates may not be relevant or reliable. The Company is not treating the historical estimate as current. In order to verify the historical estimate, a qualified person needs to review the historical data, review any work completed at the projects since the date of the historical estimate and complete a new mineral resource estimate

Terms of the Acquisition:

GoldHaven has entered into a title transfer agreement (the “Agreement”) dated June 12, 2025 with Fundamental Resources Corp. (the “Vendor”), pursuant to which it is entitled to acquire a 100% interest in the Claims located in the Cassiar Mining District, British Columbia (the “Transaction”). As consideration, the Company will issue 1,250,000 common shares (the “Consideration Shares”) to the Vendor, subject to a 36-month escrow release schedule pursuant to which 10% of the Consideration Shares will be released on completion of the Transaction, and 15% on each six month anniversary thereof. 100% of the Consideration Shares will be subject to the standard Canadian statutory four month hold period. The Transaction is expected to be completed on or about June 24, 2025.

Rob Birmingham, CEO of GoldHaven Resources, stated: “We are very pleased to expand our presence in this underexplored but highly prospective region of British Columbia. The Kuhn, Dead Goat, and M3 claims strengthen our strategic land position within the Magno Project and introduce compelling tungsten upside with additional zones of Copper, Zinc and Molybdenum to the GoldHaven story. The Kuhn and Dead Goat deposits share a geological setting similar to Cantung and Mactung, both large tungsten skarn deposits in Canada. This strategic acquisition comes on the heels of continued strong demand for commodities caught in the middle of global tariff battles—particularly tungsten. Historic work by Shell Canada, coupled with more recent exploration by Fundamental Resources, has highlighted the potential for a high-grade skarn system that could support a future development opportunity.”

The Company plans to conduct a detailed review of historic data and design follow-up exploration programs to confirm and expand the known mineralization.

VANCOUVER, British Columbia, June 10, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (“GoldHaven” or the “Company”) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce the commencement of the Auger Drill program at its 100%-owned Copeçal Gold Project located in the prolific Juruena Terrane, Mato Grosso State, Brazil. Building on momentum from prior announcements, the Company’s geological team has been busy on-site confirming Auger Drill Rig access, finalizing the grid location and establishing accommodations for the full crew during the program. Yesterday, June 9th, the drill rig began turning on the planned 2,000m Auger Drilling Program, designed to enhance geological understanding to support future diamond drilling campaigns.

The Auger Drilling Program will focus primarily on defining a 3D litho-geochemical footprint of gold distribution within the regolith profile beneath the extensive East Gold-in-Soil Anomaly. Vertical auger holes will be drilled systematically from surface to the regolith-bedrock interface—expected to range between 5 to 30m in depth—on a tight 100m x 50m grid. This methodical approach is expected to generate high-resolution data critical for the refinement of subsurface geological and structural models.

In addition to the East Anomaly, the Company will test several other zones of gold anomalism that align with interpreted structural trends, further leveraging the favourable geology observed across the Copeçal Project area.

Looking ahead, GoldHaven anticipates launching a Drone-borne Very Low Frequency (VLF) Electromagnetic Survey in early July (referred to in Figure 1). This survey will target the structural trends believed to be favourable hosts to gold mineralization, covering both the East and West Gold-in-Soil anomalies as well as their potential strike extensions. The integration of VLF geophysics with auger geochemistry will provide a robust framework for finalizing diamond drill collar locations, thereby maximizing the efficiency and effectiveness of future drilling campaigns.

Rob Birmingham, CEO of GoldHaven Resources, commented: “We are excited to enter the next phase of exploration at Copeçal. The combination of high-resolution auger geochemistry and drone-based geophysics places us in a strong position to accurately delineate high-priority targets. This integrated approach is designed to de-risk our diamond drilling program and unlock the project’s full potential. The Company remains committed to advancing its Brazilian exploration portfolio in a disciplined, data-driven manner, leveraging best-in-class techniques to generate value for shareholders.”

About the Copeçal Gold Project: A Brief History


The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s. GoldHaven’s tenements cover a total of 3,681 hectares in a geologically favourable setting within the Juruena Gold Province of Brazil.

The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining’s Tocantinzinho deposit. Additionally, the region hosts recently identified porphyry-style deposits (e.g., Serabi, Jaca) and epithermal-style deposits (e.g., X1, Aura). The presence of multiple deposit styles, along with the confirmation of large-scale gold deposits in the Juruena Province of Brazil, underscores the significant potential of the Copeçal Gold Project.

Recent exploration programs, including geochemical soil sampling, drone-mounted magnetometry surveys, and historical drilling data, indicate the presence of multiple gold-bearing structures. Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010 to 2016, including auger and air-core drilling, geophysical surveys, and rock geochemistry, identifying multiple zones of anomalous gold mineralization.

The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti’s exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential. Soil sampling grids and follow-up auger drilling in key areas revealed consistent gold values over wide zones, further supporting the presence of a substantial mineralized system.

VANCOUVER, British Columbia, April 24, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (“GoldHaven” or the “Company“) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce that it has appointed Jonathan Victor Hill as its Brazilian Country Manager.

Mr. Hill is the Founder & Principal Advisor of Exploration Outcomes Ltda. with +40 years’ experience, leading exploration, project development and mining operations globally. Mr. Hill holds a BSc (Hons) Economic Geology from University of Cape Town, South Africa and a BAppSc. Applied Geology from the Queensland University of Technology, Australia and is a Fellow of the Australian Institute of Mining and Metallurgy. He has been actively involved and/or directed several world-class gold and copper discoveries – greenfield and brownfield projects. Seasoned in governance, exploration strategy and management, he serves as a director on the boards of Royal Road Minerals (TSXV: RYR), Lavras Gold (TSXV: LGC), Avanti Gold (CSE: AGC), Spark Energy (CSE: SPRK) and was involved in Jaguar Mining, Sanatana Resources and Australian Mines.

Additionally, he held senior management roles at AngloGold Ashanti (“Anglo”) and spear-headed multi-million-dollar greenfield exploration projects in Brazil and Colombia including oversight of the exploration programs for Anglo on the Copeçal Gold Project now owned by GoldHaven.

During Mr. Hill’s tenure with Anglo between 2010 and 2016, Anglo conducted extensive exploration work across the Copeçal Gold Project and its surrounding tenements, investing approximately USD $1 million in geochemical surveys, geophysics, and drilling. This work led to the identification of multiple gold-bearing anomalies, setting the stage for further exploration.

At Copeçal, two principal, priority targets, namely the East and West targets are defined as two significant gold in soil anomalies, both extending over ~3km of strike on the property linked by a major shear structure. These soil anomalies are considered to reflect an in-situ bedrock source for gold based on wide spaced, shallow hand auger drilling completed by Anglo. Initial exploration activities at Copeçal by GoldHaven are aimed at better defining the detailed geometry of these anomalies by systematically testing the extent from surface to bedrock and laterally. It is envisaged that the Auger drilling will allow a robust litho-geochemical anomaly to be generated from which focused diamond drilling may be targeted to intersect mineralization expected at depth.

Figure 1: Copeçal Project showing the location of the Priority East and West Targets with planned Auger Drilling Grid (black dots) and VLF Drone Magnetics (Red flight plan polygons)

The Company is planning 2,000m of Auger drilling for the East Target followed by drilling in the West Target, subject to permitting. This drilling will be undertaken using a truck mounted motorized Auger (see figure 2) on a regular grid with holes spaced 50m and 100m apart along lines spaced at 200m intervals along strike. Holes will be drilled to intersect the full – oxidized and weathered regolith profile from surface to hard bedrock (refusal) which is expected to range from 10-25m in thickness. Samples will be collected at 1m intervals down the hole from which composite samples for chemical analysis will be prepared.

Figure 2: Images of the Truck mounted mechanical Auger Drill Rig and sampling techniques to be used at Copeçal to advance litho-geochemical modeling of the East and West Targets

In addition to the Auger drilling, the Company will be concurrently undertaking surface geological and structural mapping as well as a VLF* Drone survey across the property to add further important structural and geological data, which when combined with the 3D Litho-geochemical model will greatly support the all-important diamond drill targeting phases.

*VLF – Very Low Frequency is a method to measure conductivity and resistivity in rocks. Mineralized zones usually show silica enrichment (high resistivity) or sulfidation (conductivity). The method can detect anomalies of massive and disseminated zones of metallic minerals.

The Copeçal project geologist, Gustavo Rosa de Almeida (M.Sc.) is diligently working through the logistics and coordination of the upcoming programs with boots on the ground still anticipated here in Q2 2025.

In conjunction with the new appointment, the Company has entered into a resignation and mutual release (the “Release”) with the current Brazilian Tenement Manager (the “Tenement Manager”), where upon the execution of all such documents and the completion of all such actions by the Tenement Manager to the reasonable satisfaction of the Company (the “Transition Date”), the Tenement Manager will step down from his position and Mr. Hill will take over the Tenement Manager role as Country Manager.

On or before the 7th day following the Transition Date, the Company will make a payment to the Tenement Manager comprised of (i) C$15,000 in cash and (ii) subject to any required approvals of the Canadian Securities Exchange, $20,000 in common shares of GoldHaven, on a private placement basis, at a price equal to the volume weighted closing price of GoldHaven’s common shares on the Canadian Securities Exchange over the 15 trading days prior to the Transition Date (the “Payment”).

All securities issued in connection with the Payment are subject to a hold period of four months and one day pursuant to applicable securities laws.

VANCOUVER, British Columbia, March 25, 2025 (GLOBE NEWSWIRE) — GoldHaven Resources Corp. (“GoldHaven” or the “Company“) (CSE: GOH) (OTCQB: GHVNF) (FSE: 4QS) is pleased to announce the engagement of Gustavo Rosa de Almeida (M.Sc.) as the local project geologist responsible for coordinating the mobilization efforts in Brazil for the upcoming exploration program at the Copeçal Gold Project in Mato Grosso.

Mr. Almeida is a high caliber Brazilian Exploration Geologist with 10 years of experience covering a wide range of commodities and geological terranes throughout Brazil. He has a broad set of skills and experience including all phases of exploration from target generation to drill evaluation and specializes in the integration and interpretation of structural, geophysical and geochemical datasets through the complete exploration cycle. Importantly in this new role at Copeçal he has considerable highly relevant regional and local experience having recently explored over several years of Au-Cu porphyry/Orogenic systems in the Juruena-Teles Pires Polymetallic Province with successful company´s such as Bemisa and Aura Gold.

As part of preparations to mobilize the exploration team to the project, the Company has commenced stakeholder engagement and permitting activities in anticipation of initial “on the ground” work during the next 4-6 weeks. Initial activities will focus on establishing local logistic support and accommodation, hiring sampling crews, and preparing necessary access and communications systems. It is anticipated that the initial Auger Litho-geochemical drilling program will commence in Q2 2025.

At Copeçal, two principal, priority targets, namely the East and West targets are defined as two significant gold in soil anomalies, both extending over ~3km of strike on the property linked by a major shear structure. These soil anomalies are considered to reflect an in-situ bedrock source for gold based on wide spaced, shallow hand auger drilling completed by AngloGold Ashanti. Initial exploration activities at Copeçal by Goldhaven are aimed at better defining the detailed geometry of these anomalies by systematically testing the extent from surface to bedrock and laterally. It is envisaged that the Auger drilling will allow a robust litho-geochemical anomaly to be generated from which focused diamond drilling may be targeted to intersect mineralization expected at depth.

Figure 1: Copeçal Project showing the location of the Priority East and West Targets with planned Auger Drilling Grid (black dots) and VLF Drone Magnetics (Red flight plan polygons)

The Company is planning 2,000m of Auger drilling for the East Target. This drilling will be undertaken using a truck mounted motorized Auger (see figure 2) on a regular grid with holes spaced 50m and 100m apart along lines spaced at 200m intervals along strike. Holes will be drilled to intersect the full – oxidized and weathered regolith profile from surface to hard bedrock (refusal) which is expected to range from 10-25m in thickness. Samples will be collected at 1m intervals down the hole from which composite samples for chemical analysis will be prepared.

It is anticipated that a further 2,000m of Auger drilling will be undertaken over the West Target following the completion of the East Target drilling, subject to permitting.

In addition to the Auger drilling, the Company will be concurrently undertaking surface geological and structural mapping as well as a VLF* Drone survey across the property to add further important structural and geological data, which when combined with the 3D Litho-geochemical model will greatly support the all-important diamond drill targeting phases anticipated to begin in Q3 2025.

*VLF – Very Low Frequency is a method to measure conductivity and resistivity in rocks. Mineralized zones usually show silica enrichment (high resistivity) or sulfidation (conductivity). The method can detect anomalies of massive and disseminated zones of metallic minerals.

Figure 3: Schematic of the envisaged regolith profile at Copeçal (East and West Targets) that will be sampled by the upcoming Auger Drilling Program

As mentioned above prior handheld (Trado) Auger drilling completed over the East and West targets generated geochemical data confirming that the gold in soil anomalism defined at surface was in-situ (not transported) and that a bedrock source for this gold was likely present at depth. However, this sampling did not completely or adequately sample the full regolith profile or produce sufficient sample volumes to allow the development of a complete 3D litho-geochemical model of the gold dispersion in the regolith from which to confidently define targets for diamond drilling. The Auger drilling planned for both the East and West targets will now allow for the preparation of a full 3D geometrical representation of the gold distribution in the regolith profiles from surface to bedrock as represented in figure 2.

All historical data completed over the Copeçal Project by AngloGold Ashanti, including soil and hand-auger geochemical sampling, drone Magnetic and trial Induced Polarization (IP) geophysical data has been compiled into a 3D project model which is being used by the GoldHaven Geological Team to plan the upcoming exploration phases (Auger drilling, detailed VLF Drone geophysics and geological mapping will, over the coming months lead to the definition of diamond drilling targets.

About the Copeçal Gold Project: A Brief History

The Copeçal Gold Project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s. GoldHaven’s tenements cover a total of 3,681 hectares in a geologically favourable setting within the Juruena Gold Province of Brazil.

The Juruena Gold Province, also known as the Juruena Magmatic Arc, is an orogenic belt highly prospective for mesothermal shear-related and intrusion-related gold deposits, such as G-Mining’s Tocantinzinho deposit. Additionally, the region hosts recently identified porphyry-style deposits (e.g., Serabi, Jaca) and epithermal-style deposits (e.g., X1, Aura). The presence of multiple deposit styles, along with the confirmation of large-scale gold deposits in the Juruena Province of Brazil, underscores the significant potential of the Copeçal Gold Project.

Recent exploration programs, including geochemical soil sampling, drone-mounted magnetometry surveys, and historical drilling data, indicate the presence of multiple gold-bearing structures. Notably, AngloGold Ashanti previously conducted systematic exploration on the property from 2010 to 2016, including auger and air-core drilling, geophysical surveys, and rock geochemistry, identifying multiple zones of anomalous gold mineralization.

The Copeçal Gold Project benefits from extensive historical work, with AngloGold Ashanti’s exploration confirming gold and arsenic anomalies, indicative of significant mineralization potential. Soil sampling grids and follow-up auger drilling in key areas revealed consistent gold values over wide zones, further supporting the presence of a substantial mineralized system.

GoldHaven Resources completed its acquisition of Boa Gold Corp. (“Boa Gold”) on January 13, 2025, and now holds 100% ownership interest of the Copeçal Gold Project in Brazil.

About GoldHaven Resources Corp.

GoldHaven Resources Corp. is a Canadian exploration Company focused on the acquisition and development of large-scale porphyry mineralization projects in Brazil and Canada, focusing on high-potential gold, copper and critical mineral targets.

The core project in Brazil, the Copeçal gold project, is in the Juruena Gold Province within Mato Grosso, Brazil.

The key projects in Canada include the Magno and Three Guardsmen properties, adjacent to the historic Cassiar mining district, in Cassiar BC.

PROJECTS

GoldHaven Resources is advancing exploration on three 100% owned projects: Copeçal Three Guardsman and Magno Projects.

The Copeçal project is located in the sought after Juruena Gold Province known for its gold discoveries since the 1980’s. Magno and Three Guardsman properties are situated in the premier mineral districts of Northwestern British Columbia, home to some of the richest porphyry gold and copper deposits in the world.

Copeçal Project | Brazil

The Copeçal Gold Project, located in the Juruena Gold Province of Mato Grosso, Brazil, is a 3,681-hectare exploration-stage property previously explored by AngloGold Ashanti. The project hosts significant gold-in-soil anomalies, structurally controlled mineralization, and favorable geology indicative of mesothermal gold systems. Supported by road-accessible infrastructure and extensive historical data, Copeçal offers high discovery potential with upcoming exploration focused on drilling and geophysical targeting to define gold-bearing structures across the property.

Magno Project | BC, Canada

The Magno Project, located in northwestern British Columbia near the historic Cassiar townsite, is a high-potential gold-silver-lead-zinc and copper exploration project. Discovered in the early 1950s, the Magno deposit has undergone extensive exploration since the 1970s, including prospecting, geochemical surveys, ground geophysics, drilling, and underground development.
Magno boasts historic high-grade production, robust CRD mineralization, porphyry potential, and strong infrastructure access. GoldHaven is now advancing the project aiming to unlock significant value from this underexplored but richly mineralized district.

Three Guardsman Project | BC, Canada

Located in northwestern British Columbia near Haines Junction, the Three Guardsmen Project comprises 12 mineral tenures covering a highly prospective area for copper and gold-skarn mineralization. Historic exploration has identified the presence of copper, gold, molybdenum, silver, zinc, and magnetite across the property. With a favorable geological setting and multiple mineralized showings, Three Guardsmen presents a compelling opportunity for discovery in a well-endowed and underexplored district.

Unlocking Potential

In Brazil, Goldhaven benefits from having acquired the Copeçal gold project that was previously owned and operated by AngloGold Ashanti. The project is strategically situated within the Alta Floresta Gold Province, a historically productive region that has yielded substantial gold discoveries since the late 1970s.

GoldHaven aims to unlock value for shareholders through modern exploration of high-potential copper, gold, and critical mineral targets in Northwestern British Columbia, home to some of the richest porphyry copper and gold deposits in the world.
