Altair Minerals Consolidates Greater Oko Gold Project in Guyana

Strategic Acquisition Resolves Guyana's Fragmented Exploration Landscape

In a milestone transaction, Altair has successfully completed due diligence and secured shareholder approval for the Greater Oko Project acquisition, described by management as "the last El Dorado." This landmark consolidation gives Altair control over what may be one of the most prospective, untested greenstone belts globally.

The transaction also welcomes Resolute Holdings Limited as a new strategic investor through a $2.04 million cornerstone investment as part of a $2.26 million Tranche 2 placement.

What makes this acquisition particularly significant is that it overcomes Guyana's historically fragmented permit system—a barrier that has prevented systematic exploration of this gold-rich region. Under Guyana's Mining Act, exploration permits are typically limited to 1-5km² blocks arbitrarily distributed to private citizens.

"What Altair has accomplished is truly unseen in public markets," commented CEO Faheem Ahmed. "We have essentially gained control over all the most prospective greenstone within a country that remains predominantly untapped by gold exploration but hosts an extension of the same greenstone which accounts for 15% of the world's orogenic gold production."

The Oko Shear Zone: A Billion-Dollar Neighbourhood

The Greater Oko Project sits in elite company, positioned just 1.5km from the Oko West gold deposit (5.9 million ounces at 2.2g/t gold) that was recently acquired for $1 billion by GMining Ventures. It's also only 3.5km from G2 Goldfields' OMZ and Ghanie discoveries, which contain a combined 3.0 million ounces at 4.27g/t gold and have helped drive G2's market capitalisation to $1.2 billion.

The project encompasses two key areas with significant near-term exploration potential:

South Oko:

• Located along the Oko Shear Zone with 16km of strike length (compared to 6km at Oko West)
• Features a geochemical anomaly larger than the one that led to the Oko West discovery
• Initial soil sampling has already identified the high-priority W1 target, with values exceeding 100ppb gold
• Coincides with the largest magnetic high in the district sitting on the Oko Shear

North Peters:

• Hosts an advanced drill-ready target with a high-grade historical resource estimate of 251,000 ounces at 4.91g/t gold (NI 43-101 inferred category, non-JORC compliant)
• Previous limited diamond drilling confirmed the mineralisation extends beyond the 30m depth of the historical resource, with impressive intercepts including:
  • 262m at 1.6g/t gold including 38m at 8.5g/t gold
  • 43m at 10.6g/t gold from surface
  • 178m at 1.7g/t gold including 83m at 3.4g/t gold

Work Already Underway with Fast-Approaching Catalysts

Altair has wasted no time in advancing exploration at Greater Oko, with:

• The largest geochemical program in history for the Oko Shear Zone already underway, consisting of over 770 soil samples and 3km of trenching
• A world-class exploration team assembled, including Pascal Van Osta (Head of Exploration) and Rich Munson (Country Executive Director), whose prior collaboration helped deliver the 10-million-ounce Toroparu discovery in Guyana
• Drill planning at North Peters, with drilling scheduled to commence in Q1 2026

Understanding Guyana's Geological Significance

Altair Minerals Ltd gold project in Guyana represents one of the world's last underexplored gold frontiers despite hosting an extension of the same Birimian Greenstone Shield that has yielded multiple world-class gold deposits across West Africa. This geological continuity between West Africa and the Guiana Shield represents a prime opportunity for major gold discoveries.

What is the Guiana Shield?

The Guiana Shield is a geological formation that spans across parts of South America, including Guyana, Suriname, French Guiana, Venezuela, and Brazil. It represents the northern portion of the Amazon Craton and shares its geological origin with the West African Craton, specifically the Birimian Greenstone Belt.

Before the continents separated approximately 200 million years ago, these two regions were connected, which explains why they share similar geological characteristics conducive to gold formation. The Birimian-equivalent greenstone belts in the Guiana Shield host the same types of structures and lithologies that have made West Africa one of the world's premier gold-producing regions.

The Guiana Shield consists primarily of:

1. Greenstone Belts: Volcano-sedimentary sequences that are highly prospective for gold mineralisation
2. Granitoid Intrusions: Granitic rocks that intruded into the greenstone belts
3. Major Structural Features: Regional-scale shear zones that provide pathways for gold-bearing fluids

What makes the Guiana Shield particularly attractive for gold exploration is that while it shares geological similarities with West Africa, it has seen significantly less systematic exploration. This presents a rare opportunity to discover world-class deposits in a relatively untapped region.

Recent exploration successes in the region have attracted significant investment, with several companies achieving substantial valuations, including:

• G2 Goldfields: $1.2 billion market capitalisation
• Reunion Gold: $1 billion takeover by GMining Ventures
• Founders Metals: $500 million market capitalisation
• OMAI Gold Mines: $700 million market capitalisation

The Earn-In Structure: A Pathway to 70% Ownership

The definitive agreement with Adamantium Exploration Inc. provides Altair with the right to earn up to 70% interest in the Greater Oko Project through a staged earn-in process over 60 months:

1. Initial cash payment of US$100,000 within ten business days of commencement
2. Stage 1: US$400,000 in project expenditures and US$100,000 cash payment within 12 months
3. Stage 2: Additional US$500,000 in exploration and US$150,000 cash within 24 months
4. Stage 3: Additional US$500,000 in exploration and US$250,000 cash within 36 months to earn 30% interest
5. Stage 4: Additional US$500,000 in exploration and US$500,000 cash within 48 months to earn 60% interest
6. Stage 5: Final cash payment of US$500,000 within 60 months to earn 70% interest

Importantly, Altair can accelerate these payments to earn its 70% interest ahead of schedule.

Why This Matters: The Investment Perspective

Altair's Greater Oko Project represents a unique investment opportunity in the gold exploration sector for several compelling reasons:

1. Scale and Consolidation: At 590km² with potential to expand to 3,000km², this represents a land package that would be impossible for new entrants to replicate due to Guyana's fragmented permit system.

2. Proven Neighbourhood: The project sits in direct proximity to recent billion-dollar discoveries along the same geological structure.

3. Advanced Targets: With a historical resource already identified at North Peters and promising geochemical anomalies at South Oko, Altair has multiple near-term opportunities to deliver exploration success.

4. Experienced Team: The company has assembled exploration personnel with direct experience in making major discoveries in Guyana.

5. Strong Backing: The strategic investment from Resolute Holdings provides validation and financial support for the exploration program.

For investors looking for exposure to a potentially company-making gold exploration project in an emerging jurisdiction, Altair's Greater Oko acquisition represents a compelling opportunity with multiple catalysts on the horizon.

"Our neighbours have converted early geochemistry into billion-dollar assets; and with our dominant land position and a disciplined, stepwise approach, we believe Altair has a rare opportunity to replicate that success," notes CEO Faheem Ahmed.

Understanding Magnetic Highs in Gold Exploration

For investors new to gold exploration, magnetic surveys are a crucial early-stage tool for identifying potential mineralised structures. Magnetic highs often indicate the presence of magnetic minerals like magnetite that can be associated with gold-bearing hydrothermal systems.

In the case of the Oko Shear Zone, magnetic highs have proven to be reliable indicators of gold potential. At South Oko, Altair has identified a significant magnetic high coinciding with geochemical anomalies that exceed 100ppb gold in soils—a similar signature to what led to the nearby Oko West discovery.

When these magnetic features align with geochemical anomalies, they become high-priority drill targets. The fact that Altair's South Oko project shows both a larger geochemical anomaly and magnetic signature than was present at Oko West prior to its development into a 5.9-million-ounce deposit is particularly encouraging for investors following this story.

How Magnetic Surveys Guide Gold Exploration

Magnetic surveys measure variations in the Earth's magnetic field caused by different rock types beneath the surface. Certain minerals, particularly magnetite, have stronger magnetic properties than others. In gold exploration:

1. Identifying Structures: Magnetic surveys help identify shear zones, faults, and other structural features that can host gold mineralisation.

2. Mapping Lithologies: Different rock types have varying magnetic properties, allowing geologists to map potential host rocks beneath cover.

3. Targeting Alteration: Hydrothermal fluids that transport gold can alter surrounding rocks, changing their magnetic properties and creating recognisable patterns.

4. Correlation with Geochemistry: When magnetic anomalies coincide with geochemical anomalies (such as gold in soil samples), they become particularly compelling targets.

At South Oko, the magnetic high that Altair has identified suggests a significant structural feature along the Oko Shear Zone. When combined with the surface geochemical anomalies, this creates a target profile similar to what led to the nearby Oko West discovery. The fact that Altair's anomalies are larger in scale than those that led to the 5.9-million-ounce Oko West deposit further enhances the prospectivity of the South Oko area.

Conclusion

Altair's acquisition of the Greater Oko Project represents a strategic coup in the gold exploration sector. By securing this unprecedented land package in one of the world's last untapped gold provinces, the company has positioned itself for potential discovery success that could rival the recent billion-dollar valuations achieved by its neighbours.

With exploration already underway and a clear pathway to developing multiple targets, Altair Minerals Ltd gold project in Guyana offers investors exposure to a rare opportunity: systematic exploration of an extension of the prolific West African Birimian gold belt within a stable jurisdiction. The coming months promise a steady stream of news flow as the company advances its ambitious exploration program across the Greater Oko Project.
