TORONTO, Feb. 2, 2023 /CNW/ – O3 Mining Inc. (TSXV: OIII) (OTCQX: OIIIF) (“O3 Mining” or the “Corporation”) is pleased to announce the mobilization of a second drill rig at Marban Alliance, which will be focusing on its Malartic H deposit. The drilling is part of the 14,000 metre brownfield resource expansion drilling program at Marban Alliance Engineering, in furtherance of preparing a maiden resource estimate planned for Q2-2023. Malartic H is located within five kilometres of the proposed processing plant based on the Marban Alliance Pre-feasibility study – significant historical intercepts are listed in Table 1.

“We are excited to continue mobilizing more rigs to our project as we are on track to complete the metres planned for this winter at Marban Alliance. The drilling at Malartic H will enable us to complete the delineation of the main deposit and publish a maiden inferred resource estimate during Q2-2023. We are confident that our systematic drilling campaign will allow us to identify additional ounces at Marban Alliance”, said O3 Mining President and Chief Executive Officer, Mr. Jose Vizquerra.

Highlights:
  • 14,000 brownfield exploration program with 6,000 metres planned for Malartic H
  • Maiden mineral resource estimate expected in Q2-2023

About the Malartic H deposit

The Malartic H deposit has a recognized strike length of 600 metres, 300 metres wide and down to a vertical depth of 500 metres. The mineralized system is partially open laterally and completely open at depth.  It is located about 1 km to the north of Malartic Hygrade former mine, near the hinge of a regional Z-shaped fold. More importantly the Malartic H deposit is also located between the northwestern extensions of the Marbenite and Norbenite shears which host most of the resources of the Marban Alliance Engineering Project. At Malartic H, the two shears are northwest-trending and dipping around 70 degrees to the northeast. The deposit is hosted by an alternance of mafic and ultramafic volcanic sequence of the Jacola formation. As visible in the Hygrade area, numerous intermediate dyke systems are injected in the volcanic sequence. The mineralization occurs as disseminated pyrite with local visible gold in quartz veins and veinlets and disseminated in the host rock. Zones are spatially correlated with contacts between mafic and ultramafic volcanics or with the intermediate dykes. All zones are roughly subparallel.
