Altair Minerals South Oko Gold Exploration Results Deliver Breakthrough 7g/t Discovery

Altair Minerals Delivers Breakthrough Gold Results at South Oko with 7g/t Hit

Altair Minerals South Oko gold exploration results have delivered exceptional outcomes, with the company announcing significant exploration progress at its South Oko prospect in Guyana. The highlight includes an exceptional 7.03g/t gold grab sample result that marks a crucial milestone in the company's exploration campaign. This high-grade intercept represents the first confirmation of in-situ gold mineralisation within the mafic geological unit at South Oko, providing strong validation of the prospect's potential.

The exploration update encompasses multiple advancing programmes across the Greater Oko Project, including comprehensive trenching, soil sampling, and ground geophysics. Significantly, Altair has appointed OGD Drilling as its drill contractor and is preparing for an extensive 12+ month drilling campaign beginning with North Peters and expanding to South Oko.

Key Exploration Highlights

High-Grade Gold Discovery:

• 7.03g/t Au from weathered sheared quartz with pyrite at base of Trench 2
• First sub-surface confirmation of high-grade gold within mafic unit
• Additional anomalous results up to 778ppb Au from saprolite samples
• Historic alluvial tailings returning 217ppb Au and 122ppb Au

Geological Validation:

• Five trenches completed across ~1.3km strike length
• Confirmation of Oko Shear extension – the structural host to over 9Moz Au in neighbouring discoveries
• Presence of volcaniclastic-sedimentary host units analogous to the 5.9Moz Oko West deposit
• Structural deformation patterns consistent with world-class deposits along strike

Soil Sampling Progress:

• 450 sample points completed across W1 target area
• W1 represents a ~2km strike length anomaly exceeding 100ppb Au
• Anomaly larger than the soil signature that led to the Oko West discovery (~1.7km strike)
• W1 target remains open to west and southwest

Understanding Grab Samples in Gold Exploration

Grab samples are selective rock samples collected from surface outcrops or exposed areas that show visual signs of mineralisation. Unlike systematic sampling methods, grab samples target the most prospective material visible at a location and are designed to test the maximum potential grade of mineralisation present.

For investors, grab samples serve as an important reconnaissance tool that can:

• Confirm the presence of economic minerals in a prospect area
• Provide initial grade estimates for follow-up exploration
• Validate geological models and targeting approaches
• Generate early proof-of-concept data before expensive drilling programmes

While grab samples can return spectacular results, they represent point-source data and don't indicate the continuity or volume of mineralisation. The 7.03g/t Au result at South Oko is particularly significant because it was collected from in-situ material at depth within a trench, providing more reliable evidence of genuine mineralisation than surface float samples.

Drilling Programmes Accelerate Development Timeline

Altair has contracted OGD Drilling (Guyana) Inc., leveraging an established relationship through senior team members Rich Munson and Pascal Van Osta. These professionals previously oversaw 200,000m+ of drilling in Guyana with OGD. This appointment ensures proven operational expertise and execution confidence for the Altair Minerals South Oko gold exploration results programme.

Planned Drilling Campaign:

The RAB (Rotary Air Blast) drilling programme at South Oko represents a strategic approach to rapid target refinement. RAB drilling offers several advantages:

• 10x greater drilling meterage per day versus auger drilling
• Better mineralisation profile understanding and deeper penetration
• Ability to penetrate hard lateritic duricrust that masks geochemical anomalies
• Cost-effective method to identify primary mineralisation zones

Executive Commentary on Results

"The first and only sub-surface grab sample collected from within the mafic unit at SOKO has returned an exceptional 7.03g/t Au. This result represents a meaningful breakthrough, providing the first ground confirmation of in-situ high-grade gold mineralisation at the prospect," said Faheem Ahmed, CEO.

Furthermore, the systematic approach being employed demonstrates the company's commitment to thorough exploration methodology across the Greater Oko Project.

Investment Thesis: Positioned for Major Discovery

Altair's South Oko prospect demonstrates multiple characteristics that align with world-class gold discoveries in the region. The Altair Minerals South Oko gold exploration results showcase geological analogues consistent with neighbouring high-value assets.

Geological Analogues:

• Same extensional structural systems as neighbouring multi-billion dollar assets
• Geological sequence mirroring deposits along the Oko Shear corridor
• Structural deformation patterns consistent with 9Moz+ discoveries
• Proximity to 5.9Moz Oko West deposit expected in production within 18 months

Scale and Infrastructure:

• 590km² contiguous landholding in emerging greenstone belt
• 1.5km distance from established major discovery
• Established exploration camp with operational capabilities
• Multiple high-priority targets across Greater Oko Project

Market Context:
Recent success stories in the region demonstrate the exceptional value creation potential:

• G2 Goldfields: $2.2 billion market capitalisation
• Reunion Gold: $1 billion takeover by GMining Ventures (2024)
• OMAI Gold Mines: $1.3 billion market capitalisation

The Guiana Shield represents an extension of West African Birimian geology that has underpinned world-class discoveries across Ghana, Ivory Coast, and Burkina Faso. However, unlike African counterparts, Guyana remains significantly underexplored while offering superior political stability and mining-friendly jurisdiction.

Why Investors Should Monitor These Developments

The confluence of high-grade gold confirmation, systematic exploration advancement, and imminent drilling programmes positions Altair as a compelling growth story. The 7.03g/t Au result provides crucial proof-of-concept validation whilst the expanded exploration scope through RAB drilling accelerates target refinement ahead of major diamond drilling campaigns.

Key Investment Catalysts:

• North Peters diamond drilling commencing mid-April (3,000-5,000m)
• South Oko RAB programme running parallel for rapid target refinement
• Ground geophysics results expected shortly to complement geological data
• Major South Oko diamond programme (10,000-15,000m) following North Peters

The systematic, methodical approach being employed across multiple targets maximises discovery probability. In addition, the experienced team's proven track record in Guyana provides execution confidence for delivering on the potential identified in the Altair Minerals South Oko gold exploration results.

Regional Context and Opportunity

With neighbouring discoveries validating the regional potential and Altair's strategic positioning on the same structural corridor, the company offers significant upside exposure to potential major gold discoveries. Consequently, the upcoming drilling programmes represent critical catalysts for value creation.

The Greater Oko Project benefits from established infrastructure and proximity to proven resources, creating operational efficiencies that enhance project economics. For instance, the existing exploration camp and established contractor relationships reduce execution risks typically associated with remote exploration projects.
