O3 Mining - Marban Continues To Show Growth Potential

TSXV:OIII | OTCQX:OIIIF - O3 Mining

TORONTO, Dec. 22, 2022 /PRNewswire/ - O3 Mining Inc. (TSXV: OIII) (OTCQX: OIIIF) ("O3 Mining" or the "Corporation") is pleased to announce it continues advancing its Marban property in Val-d'Or Quebec, Canada, with exploration efforts focused on expanding the life of mine of the Marban project, as well as providing results from its 2022 infill and exploration drill program.

Unlocking growth potential at Marban – Expanding the Life of Mine ("LOM")

• Marban Engineering near pit expansion – adding value in Years 0 -10

• Marban Engineering resource growth – adding value in Years 10 plus

• Marban Regional – testing gold and Volcanogenic Massive Sulphide ("VMS") targets

"2023 will be an ambitious year for O3 Mining as we work towards completing the Marban Engineering Feasibility Study ("FS"), as well as engage in exploration activities to unveil Marban's growth potential over our 8,500 hectares property across the railroad from a world class deposit such as the Canadian Malartic Mine. Marban Engineering is a robust standalone project that can add more value to its NPV of C$463 million by discovering new ounces to extend the LOM. For every additional year of production (160,000oz Au), the impact on the fundamental value is between C$80 million to C$100 million.The more ounces added, the more value added to the project, therefore preparations are well underway for drill campaigns at Marban Engineering and Marban Regional, as well as compilation work from our summer soil sampling and channel sampling campaigns as we boost our exploration efforts.", said O3 Mining President and Chief Executive Officer, Mr. Jose Vizquerra.

Marban Engineering Near Pit Expansion – adding value in Years 0-10

• Norlartic and North resource and reserve update as part of the FS. A total of 8,800 metres has been drilled to convert a remaining 50,000 oz of gold from the inferred to the indicated category.

• Kierens: a few drill holes were completed to fill in a gap and connect the Kierens main pit with the Kierens satellite pit.

Marban Engineering Resource Growth – adding value in Years 10 plus

• Resource growth near surface

• Resource growth for underground potential.

Marban Regional – Testing gold and VMS targets

• Gold - High resolution drone mag survey completed Q1-2022, soil sampling campaign, compilation of historic results, mapping, and channel sampling of historic strippings

• Base Metals - Discovery of the Cu-Au-Ag-Zn exhalite – type and VTEM survey
