O3 Mining Initiates Drilling at Marban Regional

"After an extensive field season of compilation work, soil sampling, and geophysical surveys in 2022, we are very excited to have initiated drilling at Marban Regional. This is a vast underexplored area, offering lots of potential for discovery, especially along the same shear structures that host the Marban and Norlartic deposits", said O3 Mining President and Chief Executive Officer, Mr. Jose Vizquerra.

• 9,300 metres of greenfield diamond drilling program;
• Testing of magnetic features similar to the Marban and Norlartic deposits along the northwestern extension of the Marbenite and Norbenite shears, several gold-in-soil anomalies, and the Ludovick occurrence along the Parfouru fault, as well as follow-up drilling on historical intercepts within the Cadillac and Temiskaming sediments south of the Parfouru fault.

In Q1-2022, a high-resolution drone mag survey was completed to help identify the northwestern extent of the Marbenite and Norbenite shear zones. The characteristic low-mag signature of the Marban and Norlartic deposits were identified along these structures and will be drill tested. Furthermore, a soil sampling campaign totalling 4,411 samples was completed. Assay results from the soil sampling program reveal numerous gold-in-soil anomalies in underexplored areas.

Follow up work will be initiated on significant historic drill intercepts by NioGold Mining Corp. at the Ludovick mineral occurrence along the Parfouru fault and within the Cadillac and Timiskaming sediments contiguous to the Canadian Malartic mine property. The Ludovick occurrence is associated with quartz-tourmaline-arsenopyrite veins along the Parfouru fault and correlates with corridors of anomalous gold and arsenic values from the 2022 soil survey. A previous drilling campaign by Niogold Mining returned many significant intercepts within the area (Press Release, November 6, 2012, Sedar Issuer Profile: Niogold Mining)

• 23.4 g/t Au over 1.0 metre in hole CW-12-083 at a vertical depth of 115 metres.
• 9.55 g/t Au over 1.1 metres in hole CW-12-090 at a vertical depth of 22 metres, 350 metres to the south of the Ludotresvick trend, within a lower grade interval of 0.58 g/t Au over 49.1 metres
• 9.06 g/t Au over 2.0 metres in hole CW-12-075 at a vertical depth of 115 metres.
