O3 Mining Initiates Drilling at Marban Alliance Regional

January 19, 2023


TORONTO, Jan. 19, 2023 /CNW/ – O3 Mining Inc. (TSXV: OIII) (OTCQX: OIIIF) (“O3 Mining” or the “Corporation”) is pleased to announce the commencement of the exploration drilling program at Marban Alliance Regional. The drilling program will consist of 9,300 metres to test for gold targets in this underexplored part of the property covering approximately 5,000 hectares.

“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 Alliance Regional. This is a vast underexplored area, offering lots of potential for discovery, especially along the same shear structures that host the Marban Alliance 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 Alliance 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.
Magnetic features similar to the Marban Alliance and Norlartic signature along the Marbenite and Norbenite shears

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 Alliance 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.

Ludovick and surrounding mineral occurrences

Follow up work will be initiated on significant historic drill intercepts by Niogold Mining Corporation 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 holeCW-12-083 at a vertical depth of 115 metres, located some 600 metres NW of the Ludovick deposit along strike
    • 9.55 g/t Au over 1.1 metres in holeCW-12-090 at a vertical depth of 22 metres, Ludovick deposit.
    • 9.06 g/t Au over 2.2 metres in holeCW-12-075 at a vertical depth of 115 metres, within a lower grade interval of0.58 g/t Au over 49.1 metres and located 350 metres south of the Ludovick trend.
