ISSUED ON BEHALF OF GOLDHAVEN RESOURCES CORP.

GoldHaven Resources (CSE: GOH | OTCQB: GHVNF) has completed the East Anomaly drilling phase[1] at its Copeçal gold project in Brazil’s active Juruena Gold Province, with assays from four diamond drill holes expected shortly and drilling now underway at the West Anomaly.

When one of the world’s largest gold producers spends over $1 million exploring a property and identifies a 6-kilometer strike of gold anomalies, they’re following something real. Now that same ground has been drilled, and the market awaits the results.

That’s GoldHaven Resources’ (CSE: GOH) (OTCQB: GHVNF) story across two continents… beginning at Copeçal, Brazil.

The South American Opportunity: Brazil’s Juruena Gold Province

GoldHaven’s flagship Copeçal Gold Project sits in Brazil’s Juruena Gold Province – a belt that’s been producing gold since the 1980s and continues to attract major mining companies today.

The property covers 3,681 hectares (9,096 acres) of strategically positioned ground in the heart of this proven district.[2]

The AngloGold Ashanti Effect:

From 2010-2016, one of the world’s largest gold producers spent over $1 million systematically exploring this exact property. Their work defined a 6-kilometer strike of gold-in-soil anomalies.

Think about that. Six kilometers of surface gold signatures that attracted a major’s sustained attention and investment. That’s not random prospecting – that’s systematic targeting of a significant geological system.

The insider advantage: GoldHaven’s Country Manager, Jon Hill, previously worked for AngoldGold Ashanti and was instrumental in identifying Copeçal as a strategic target during his tenure there. This gives GoldHaven unique institutional knowledge about why one of the world’s premier gold companies prioritized this specific ground.

Why Brazil’s Juruena Province Matters

Juruena isn’t theoretical geology – it’s an active gold production district.

The belt hosts multiple operating mines and has consistently attracted major mining companies. GoldHaven’s Copeçal project sits in similar geology to Altamira Gold’s significant discoveries in the same belt.

Mineral deposits in established districts often occur in clusters due to shared geological processes. GoldHaven isn’t prospecting in virgin territory – they’re systematically exploring a district with demonstrated production records and continued industry investment.

The geological validation: The previous work identified two priority drill targets using modern geophysics. Following comprehensive auger drilling and geophysical surveys, GoldHaven commenced its maiden drilling program in October 2025[3].

The Infrastructure Advantage Few Explorers Have

Most exploration projects are in the middle of nowhere, requiring years and millions of dollars to build basic infrastructure.

Copeçal has infrastructure already in place:

Year-round road access to the property
Just 60km from Alta Floresta (population 50,000 with daily commercial flights)
Located in Mato Grosso, one of Brazil’s most mining-friendly states
Favorable permitting environment and local support
Brazilian real weakness makes local costs favorable for international companies

Translation: Lower capital requirements for development, faster timelines, and reduced execution risk compared to remote exploration projects.

Drilling Update: East Anomaly Completed, Assays Pending

GoldHaven has completed the East Anomaly drilling phase, marking a significant milestone in the company’s systematic exploration of this major-validated target[4].

October 2025 drilling milestones:

Four diamond drill holes completed totaling approximately 420 meters along a 200-meter strike length at the East Anomaly
Strong structural deformation and hydrothermal alteration intersected in multiple holes
Enhanced alteration and veining intensity observed, including zones of silicification, biotite, quartz veining, sericite-chlorite, and weak carbonate alteration
Fifth hole collared – marking the first-ever drill test of the West Anomaly
Initial assay results from East Anomaly holes expected in the near term

CEO Rob Birmingham said the alteration styles and structural features observed are consistent with a robust hydrothermal gold system. The company is now testing the West Anomaly – a large gold-in-soil and auger anomaly spatially associated with a strong VLF conductive feature.

The coming weeks will reveal whether GoldHaven’s systematic approach to testing AngloGold Ashanti’s targets delivers meaningful results for shareholders.

Current Market Positioning

Comparative Context:

AngloGold Ashanti invested over $1 million exploring Copeçal
GoldHaven’s current market capitalization: ~$5 million (as of November 2025)
East Anomaly drilling phase completed with four holes totaling 420 meters
Assay results pending from systematic testing of major-identified targets
West Anomaly drilling now underway in an active gold production district

The current market valuation appears to reflect early-stage exploration uncertainty rather than the quality of the geological targets, completed drilling at priority zones, prior work by a major producer, or infrastructure advantages.

Gold Market Backdrop

Favorable commodity environment:

Gold trading above $3,950/ounce
Continued central bank buying supporting prices
Geopolitical uncertainty driving safe-haven demand
Brazilian real weakness creating cost advantages for international companies

GoldHaven is testing major-validated targets in a proven gold district during a strong commodity cycle, with initial assay results expected shortly.

Geographic Diversification: Canadian Upside

While Brazil provides the immediate catalyst, GoldHaven offers additional upside through its expanded Canadian portfolio in British Columbia’s historic Cassiar district.

The Canadian opportunity:

The Cassiar district produced millions of ounces of gold historically before being abandoned in the 1990s when the asbestos mine shut down. The gold didn’t leave – the people did.

GoldHaven has been methodically acquiring historical drilling data from companies like Shell Canada and in September 2025 completed summer exploration programs[5] collecting 354 rock samples at Magno and 126 at Three Guardsmen. In October 2025, the company acquired additional Hamel claims adding 429.46 hectares to further consolidate its district-scale position[6].

Canadian Assets:

Magno Project: District-scale polymetallic target now totaling 36,003 hectares in proven Cassiar district²
Three Guardsmen Project: Copper-gold skarn potential near historical producers³
Paved highway access within 12km
Existing airstrip on property
Power infrastructure nearby

Recent fieldwork identified the Cassiar Stock – a 72 Ma Cretaceous granite along the Cassiar Batholith’s eastern margin – as a key control on mineralization. Mapping confirmed strong correlation between phases of the Cassiar Stock and mineralized showings, prompting the strategic land expansion.

Medium-term catalysts:

Assay results from summer 2025 field programs (354 samples at Magno, 126 at Three Guardsmen)
Follow-up exploration on expanded 36,003-hectare land position
Systematic testing of Shell Canada historical targets

FACT: GoldHaven now has a total strategic land position of 130,000+ hectares across proven geological districts in Brazil and Canada.

The Systematic Approach

GoldHaven demonstrates a methodical approach to district-scale exploration:

Target proven districts with infrastructure ✓
Acquire comprehensive historical data ✓ (AngloGold’s $1M+ program at Copeçal)
Apply modern geological understanding ✓
Secure strategic land positions ✓ (130,000+ hectares)
Execute systematic exploration programs ✓ (East Anomaly drilling completed, assays pending)

This isn’t random prospecting. It’s methodical exploration of historically productive areas using modern techniques, following in the footsteps of major mining companies.

Management Alignment and Systematic Approach

CEO Rob Birmingham maintains a significant equity position, aligning management interests with shareholder outcomes.

The GoldHaven team brings relevant experience:

Jon Hill (Country Manager): Previously with AngloGold Ashanti, instrumental in identifying Copeçal as a strategic target
Deep knowledge of both Brazilian and Canadian geological environments across the team
Team track record of systematic, data-driven exploration

The Pattern Recognition

Historical Mining Success Stories Follow This Sequence:

Identify districts with past production ✓
Apply modern geological understanding ✓
Acquire positions during early-stage exploration ✓
Systematically test priority targets ✓ (East Anomaly drilling complete, assays pending)
Potential sale to major mining companies

Examples:

MAG Silver: Small-cap exploration to $2.1 billion Pan American acquisition[7]
Great Bear: Overlooked property to $1.8 billion Kinross purchase[8]
Pretium: Exploration concept to Brucejack $2.8 billion sale to Newcrest[9]

Note: Past performance of other mining companies does not guarantee future results for GoldHaven. Each project has unique risks and characteristics.

What the Coming Weeks Will Tell

Immediate catalysts:

Assay results from East Anomaly drilling – four holes totaling 420 meters testing the 6km gold-in-soil anomaly
West Anomaly drilling results – first-ever drill test of this large gold-in-soil target
Data from systematic testing of AngloGold Ashanti-identified priority zones

Additional upside:

Assay results from Canadian summer 2025 programs (480 total samples)
Follow-up work on expanded 36,003-hectare Magno position
Systematic testing of historical Shell Canada targets

The market will ultimately determine whether systematic exploration efforts justify higher valuations. GoldHaven at ~$5 million market cap represents a typical early-stage exploration valuation, though the combination of completed drilling at major-validated targets, imminent assays from a 6-kilometer anomaly, and infrastructure advantages suggests the market may be pricing in considerable uncertainty that assay results could potentially resolve.

Final Assessment

Every significant mining discovery was once at the early exploration stage. Success requires geological merit, systematic exploration, infrastructure access, and favorable market conditions.

GoldHaven has completed drilling a 6-kilometer gold anomaly identified by one of the world’s largest gold producers, in an active production district, with infrastructure already in place, during a strong gold market. Initial assay results are expected in the near term.

The next chapter is being written now with assays pending from completed drilling at Copeçal and additional exploration advancing across 130,000+ hectares in proven districts.

Historical geological evidence and prior work by AngloGold Ashanti provided the foundation. Systematic drilling has tested the targets. The ultimate value will be determined by assay results and market conditions.
