Altair Minerals (ASX: ALR) has unveiled significant IP geophysical results at its North Peters prospect, identifying major untested targets adjacent to high-grade gold intercepts.
These results, alongside recent exploration updates, point to substantial potential for resource expansion within its Greater Oko Project in Guyana.
Altair plans further drilling at North Peters in Q1 2026, and has the right to earn up to 70% of the Greater Oko Project, with all tenements in good standing.
North Peters Targets Emerge From IP Survey
IP geophysics at North Peters has pinpointed a major untested chargeability high, designated C1.
This anomaly boasts a 900m strike length, with only 300m drilled to date.
Additionally, a 2.7 km resistivity corridor, named R1, was defined. Only 600m of this corridor has been drilled, yet it aligns with previously reported high-grade intercepts.
Further exploration has identified two untested chargeability highs, C2 and C4, which combine for an impressive 550m strike length. These targets remain open at the survey boundaries.
Notable periphery intercepts near the C1 target include 109m @ 2.04 g/t from 47m, 63m @ 2.25 g/t from 55m, and 89m @ 2.40 g/t from 45m. Other significant results include 43m @ 10.56 g/t from surface and 14m @ 6.13 g/t from 49m.
Greater Oko Project Development
The company recently secured A$13.0 million through an institutional placement, significantly bolstering its financial position.
Altair Minerals ended December 2025 with a robust A$12.2 million cash balance.
This funding fully supports a minimum 15,000m drill programme planned for the Greater Oko Project. Drilling is anticipated to commence in Q1 2026.
The Greater Oko Project spans 590 km2 along the Oko Shear Zone in Guyana. This strategic location is adjacent to billion-dollar Oko West discoveries, highlighting its substantial exploration potential.
South Oko Anomaly Expansion
Recent updates confirm the South Oko soil anomaly has extended by an additional 1 km to the south and west.
Critically, this anomaly remains open in both directions, suggesting further expansion is possible.
The South Oko area now comprises three distinct, open targets. W1 boasts a 2.0 km strike length with gold values exceeding 100 ppb Au. W3 extends for 1.6 km with assays above 50 ppb Au, and E1 measures 1.3 km with gold concentrations greater than 100 ppb Au.
Extensional sampling is actively underway at the W1 target. Auger results from this work have indicated strong continuity of mineralisation into the underlying saprock, a positive sign for future drilling.
Olympic Domain Dispute Continues
Altair Minerals continues to navigate a dispute with BHP Group (ASX: BHP) regarding its Olympic Domain copper project in South Australia.
A Wardens Court hearing for this matter is officially scheduled for 19 February 2026.
The disagreement stems from BHP's stated intentions to use Altair's project area for infrastructure related to BHP's nearby Oak Dam Deposit. Previous discussions between the two parties regarding the Olympic Domain's value led to the current adjudication process.
Altair Minerals remains focused on achieving a commercial resolution with BHP. A favourable outcome from this process could unlock substantial value for the Olympic Domain asset.
Altair's Next Steps
Altair Minerals is strategically advancing its exploration portfolio, with the North Peters IP results providing clear drill targets for Q1 2026.
While the Greater Oko project shows significant promise, the ongoing BHP dispute and the company's reliance on funding remain key considerations for investors.
