Altair Minerals Limited has commenced maiden reverse circulation drilling at its South Oko and North Peters prospects, expanding active operations across the Greater Oko project to three drill rigs as it ramps up toward a target rate of approximately 8,000 metres per month by October 2026.

The expanded field activity follows recent maiden trenching results at South Oko's W1 target, which yielded intercepts including 10 metres at 10.15g/t gold in trench TR-W1-06. The 15,000-metre Phase I reverse circulation program at South Oko is designed to test the vertical continuity of this in-situ mineralisation and explore potential concealed shear zones extending beneath leached duricrust.

At North Peters, a 2,000-metre Phase I reverse circulation program has started alongside an ongoing 5,600-metre diamond drilling campaign. These current operations represent a substantial expansion from previous exploration, which was limited to a single diamond rig operating at North Peters.

“This is the point where Greater Oko moves from preparation and target generation into genuine multi-front discovery drilling. Maiden RC drilling is now underway at both South Oko and North Peters, alongside our continuing North Peters diamond program, taking us to three active rigs as we ramp-up towards approximately 8,000m of drilling per month.”

Altair acquired the Greater Oko project through a definitive acquisition agreement signed in October 2025 covering an initial area of 590 square kilometres. The exploration campaigns are backed by a A$28.2 million strategic placement secured from Endeavour Gold Corporation in April 2026 at an issue price of A$0.043 per share, which brought the company's pro-forma treasury to approximately A$40 million. In the surrounding district, Liberty Metals Ltd executed a binding four-year option agreement to acquire a 90% interest in the Oko North and Oko South gold projects in August 2026.
