Altair Minerals Ltd Drilling Campaign Targets High-Grade Gold Discovery

Outstanding Historic Trenching Results Drive Expanded Scope

The Altair Minerals Ltd drilling campaign has expanded beyond initial plans following the discovery of exceptional historic trenching data at North Peters. These previously unreported results demonstrate the significant untapped potential across Altair's tenure, with mineralisation remaining open at multiple locations.

According to the announcement, the trenches were positioned on the northwestern boundary of the known mineralisation system, with several ending in significant grades. Furthermore, TR0406 finished with 3m @ 6.56g/t Au and TR0506 concluded with 3m @ 3.21g/t Au. This suggests substantial extension potential beyond the current drilling envelope, creating immediate high-priority targets for the current campaign.

CEO Faheem Ahmed commented:
"This program marks the commencement of a significant step-change in our exploration activities, with a continuous 12-month drilling program. Initial drilling will test compelling trench results including 16.5m @ 9.68g/t Au, positioning the Company for its next phase of growth."

Strategic Drilling Approach Across Multiple Targets

The announcement outlines Altair's drilling strategy, which reflects the varying maturity levels across its target areas. In addition, the company has allocated minimum allocations of 10,000m each to both North Peters and South Oko prospects.

North Peters Strategy:

• Validation drilling: Confirm historic intercepts on system periphery
• Extension testing: Target northwest corridor where trenches ended in mineralisation
• Infill programs: Test areas between known intercepts for resource definition

South Oko Strategy:

• Discovery drilling: Test virgin geochemical targets W1 and W3
• Depth testing: RAB drilling to 50-75m beneath duricrust cover
• Regional extension: Expand beyond current 4km tested strike length

The company reports it will utilise scissor hole configurations with 45-degree dips and alternating azimuths, optimising coverage while maintaining cost efficiency. According to management, three separate drilling programs will operate simultaneously by month-end. However, this is supported by ongoing trenching, soil sampling, and geophysical surveys.

Understanding Orogenic Gold Systems: What Makes Greater Oko Special

Orogenic gold deposits represent some of the world's most significant gold discoveries, forming in mountain-building environments where hot, gold-bearing fluids migrate along major fault systems. These deposits are characterised by their substantial size potential, high-grade zones, and association with regional shear structures.

The Oko Shear is described as representing exactly this type of world-class mineralising system. For instance, it's a major structural corridor that has already delivered over 9 million ounces of gold resources across a 5km tested strike length. The company states that Altair's 15km of untested shear zone provides exceptional discovery leverage, particularly given the demonstrated continuity of mineralisation along the structure.

Why this matters to investors: Orogenic systems often contain multiple deposits along their strike length. With neighbours having defined four separate discoveries across their tenure, Altair's significantly larger land position suggests potential for discovering multiple high-grade zones across its 590km² project area.

Key geological advantages reported:

• Birimian Greenstone geology: Extension of West African gold districts
• Structural control: Major shear zones provide fluid pathways
• Proven system: Adjacent discoveries validate regional potential
• Scale advantage: Largest contiguous position in district

Investment Thesis: Last Major Opportunity in Consolidating District

The investment case for Altair centres on three compelling factors that distinguish it from typical early-stage exploration companies. Consequently, this positions the company uniquely in the current market landscape.

1. Irreplaceable Land Position

Altair's 590km² contiguous tenure cannot be replicated due to Guyana's fragmented permit system, where typical holdings average just 4km². This scale advantage provides multiple discovery opportunities across a proven mineralised district.

2. District Validation Through Takeovers

Recent transactions demonstrate the exceptional value being placed on Oko Shear assets:

• 2024: Reunion Gold acquired for $1 billion
• 2026: G2 Goldfields acquired for $3 billion
• Combined resources: >9 million ounces across 5km strike

3. Exploration Leverage

With 15km of untested Oko Shear strike compared to 5km already drilled by neighbours, Altair offers 3x the discovery potential of assets that have attracted billion-dollar valuations.

Why Investors Should Follow This Company

Altair Minerals represents a unique opportunity to gain exposure to what could become Guyana's next major gold discovery. The company has assembled the critical elements for exploration success: a world-class land position, proven geological systems, and experienced management with deep regional knowledge.

Key tracking reasons:

1. Discovery Potential

The 15km of untested Oko Shear provides exceptional leverage to district-scale mineralisation. Furthermore, historical precedent shows multiple discoveries along strike.

2. Strategic Value

As the last major independent player in a consolidating district, Altair could become an acquisition target. This potential emerges as majors seek to build critical mass in this emerging gold province.

3. Near-term Catalysts

The 30,000m drilling program will generate continuous news flow throughout 2026. However, this comes with potential for multiple discovery announcements across different target areas.

4. Regional Momentum

Guyana's emergence as a premier gold jurisdiction, combined with its pro-mining regulatory environment, provides an ideal backdrop for value creation.

5. Management Execution

The rapid progression from project acquisition to drilling commencement demonstrates the team's ability to advance assets efficiently in challenging jurisdictions. Consequently, this track record builds investor confidence.

Key Takeaway:
Altair Minerals has positioned itself as the final major exploration opportunity in Guyana's premier gold district. With 30,000m of drilling commencing across world-class targets and recent billion-dollar takeovers validating the region, investors should closely monitor developments as the company pursues what could be the district's next significant discovery.

The convergence of exceptional geology, strategic positioning, and intensive exploration creates a compelling investment proposition. This unique combination targets those seeking exposure to high-impact gold discovery potential in one of the world's most prospective emerging districts.

Altair Minerals Limited (ASX: ALR) has commenced its inaugural drilling program at the Greater Oko Project in Guyana, marking a pivotal moment for the company. This significant milestone represents the beginning of systematic exploration of what could be one of the region's most significant gold discoveries. The 30,000-metre program combines 15,000m of diamond drilling with 15,000m of RAB drilling, representing the largest exploration effort in the project's history.

The Altair Minerals Ltd drilling campaign gains added significance following recent $1 billion and $3 billion takeovers of adjacent projects by GMining Ventures. This positions Greater Oko as the last major exploration opportunity in this highly prospective district. With 590km² of contiguous tenure – the largest gold exploration landholding in Guyana's history – Altair controls approximately 15km strike length of the renowned Oko Shear zone.
