O3 Mining Inc. has announced the third and final set of assay results from its 28,868-metre drilling campaign on the Malartic H deposit, part of the Marban Alliance project in Val-d’Or, Québec. The campaign aimed to upgrade inferred mineral resources to indicated status.

Highlights from the latest results include:

• 30.0 g/t Au over 3.0 metres, including 101 g/t Au over 0.7 metres in hole O3MA-24-707 at a vertical depth of 241.4 metres.

• 40.2 g/t Au over 1.9 metres, including 151 g/t Au over 0.5 metres in hole O3MA-24-701 at 141.3 metres depth.

• 1.8 g/t Au over 39.8 metres in hole O3MA-24-642 at 55.6 metres depth.

“We are pleased to complete this campaign and receive the full set of assays. These results reinforce the strategic value of Malartic H within the Marban Alliance Project and position us to update our mineral resource estimate,” said José Vizquerra, President and CEO of O3 Mining.

Strengthening the Marban Alliance

The Malartic H deposit spans 950 metres in strike, 300 metres in width, and extends to a depth of 500 metres. Located within five kilometres of the proposed processing plant, the deposit is strategically positioned between the Marbenite and Norbenite shears, known to host significant gold resources. Mineralization includes disseminated pyrite and visible gold in quartz veins and volcanic units.

2024 Drilling Campaign Summary

The completed campaign comprised 143 drill holes, with final results covering 45 holes. Previous assays reported included:

• 119.1 g/t Au over 2.5 metres (April 2024).

• 102.0 g/t Au over 1.5 metres (July 2024).

These results will inform the updated resource estimate and support future development plans for the Marban Alliance Project.

Next Steps

With assay data fully compiled, O3 Mining will focus on upgrading resources from inferred to measured and indicated categories, aiming to unlock the deposit’s full potential.
