South Oko Exploration by Altair Minerals Validates Neighbouring Geology

Altair Minerals Limited (ASX: ALR) has delivered an encouraging exploration update from its South Oko exploration by Altair Minerals Ltd, with trenching commencing ahead of schedule and the first completed trench validating the geological extension of the same host rock package found at neighbouring billion-dollar deposits. The company is rapidly scaling up operations with multiple parallel exploration activities designed to fast-track the project toward drilling.

First Trench Validates Geological Target at South Oko

The completion of Trench SO-T04, positioned directly on the Oko Shear Zone, has identified numerous occurrences of weathered veinlets, quartz carbonate, and sulphides—the identical host geological package found at neighbouring deposits. This geological continuity represents a critical validation of the South Oko exploration by Altair Minerals Ltd potential, confirming that the same structural and lithological conditions that host major discoveries in the region extend onto Altair's tenement.

Key findings from the initial trenching include:

• Weathered carbonaceous sediments consistent with productive geology
• Sulphide mineralisation within the saprolite layer
• Quartz carbonate veining indicating hydrothermal activity
• Geological continuity with the Barama-Mazaruni Greenstone belt

CEO Faheem Ahmed commented: "Trench No. 4 is the first sub-soil ground proof at South Oko, which has confirmed key geological continuity from our neighbours, hosting weathered carbonaceous sediments and sulphides."

Comprehensive Multi-Phase Exploration Program Underway

Furthermore, Altair has implemented an aggressive exploration strategy with four parallel work streams operating simultaneously to maximise efficiency and accelerate target definition:

Phase 1 Trenching Program

• 4 trenches totalling ~3km covering E1 and W1 targets
• East-west orientation to crosscut the Oko Shear Zone
• 2.5-3 metre depth penetrating into saprolite layer
• Systematic sampling at 1-2 metre intervals

Enhanced Auger Program

• Mechanised auger deployed for improved penetration through laterite cap
• Targeting saprolite layer to identify in-situ anomalies
• Narrowing broad soil anomaly halo for focussed drilling targets

Expanded Geochemical Sampling

• Second batch of soil samples delivered to laboratory
• Multiple sample types pending assay results
• Results-driven approach guiding Phase 2 trenching

Imminent Geophysical Survey

• Ground Gradient IP, Pole-Dipole, and Magnetics surveys planned
• 3D structural mapping to identify hosting structures at depth
• Final exploration phase before drilling commences

Understanding Trench Sampling in Gold Exploration

Trenching represents a crucial intermediate step between surface geochemistry and drilling in gold exploration. Unlike soil sampling, which tests weathered material near surface, trenching excavates down to the saprolite layer—the zone where bedrock has been chemically weathered but retains its original structure.

This technique is particularly valuable because:

• In-situ sampling: Material hasn't been transported, providing direct evidence of underlying mineralisation
• Structural mapping: Reveals vein orientations, fault patterns, and geological contacts
• Target refinement: Converts broad soil anomalies into discrete drill targets
• Cost efficiency: Significantly cheaper than drilling while providing similar geological information

For instance, successful trenching that confirms geological continuity with neighbouring deposits dramatically increases the probability that subsequent drilling will intersect mineralisation.

Strategic Positioning in World-Class Guyana Gold Province

South Oko sits within the Greater Oko region, positioning Altair alongside some of the most valuable gold discoveries in recent years. The project benefits from exceptional geological and strategic advantages:

Geological Advantages

• Same greenstone belt hosting 5.9Moz discoveries
• 1.5km proximity to established resources
• 590km² contiguous landholding providing exceptional scale
• Underexplored jurisdiction with significant discovery potential

Jurisdiction Benefits

• Politically stable pro-mining environment
• Established infrastructure supporting regional development
• Proven exploration success by multiple operators
• Extension of West African geology with similar world-class potential

Accelerated Timeline Toward Drilling

However, Altair's systematic approach is designed to compress typical exploration timelines through parallel execution of multiple work streams:

Immediate Term (Next 2 weeks)

• Complete Trench 4 sampling and dispatch to laboratory
• Advance one-third of Trench 3 sampling
• Receive first batch of soil assay results
• Commence line cutting for geophysical surveys

Short Term (Next 1-2 months)

• Complete Phase 1 trenching program (4 trenches, 3km total)
• Execute ground geophysical surveys across W1 and E1 targets
• Receive comprehensive assay results from trenching and soil programs
• Design Phase 2 trenching (additional 5km) based on results

Medium Term (Next 6 months)

• Maiden drilling program targeting highest-priority anomalies
• Resource definition drilling if initial results warrant
• Expand exploration to additional targets across 590km² tenure
