O3 Mining Inc. announced its 2021 exploration and development plans focused on unlocking value in the historic Val-d'Or gold region of Québec. It includes a 150,000 meter drilling campaign using up to 12 rigs on the Marban project and Alpha property, and to initiate a Pre-Feasibility Study on Marban. In June 2020, O3 Mining initiated a well-funded 150,000 meter drilling campaign on its projects in Val-d'Or Québec, which will continue through 2021. 50,000 metres of drilling. Test extensions of the ore deposits included in the September 2020 PEA to grow the mineral resource base specifically focused on the Norlartic–Kierens, North-North, North Shear, Marban, and the Gold Hawk deposits. Other drilling targets, Orion #8, MK, Malartic H, Marban NE, and Camflo deep, include extensions of historical mineralized zones within 3 kilometres of the PEA pit shells, which offer additional potential to increase resources within the Marban mining project area. Initiate Marban PFS in 2021, with a focus on fieldwork, metallurgical test work, and economic trade-off studies, in addition to advancing environmental impact studies. The company will also continue to explore the geological potential of the Marban project. 100,000 meters of drilling. Expand known deposits to depth at Orenada, Simkar, Akasaba, and Bulldog and proceed to a resource estimate when the company feel there is enough resource to generate an economic scenario. Follow-up on significant drill intercepts to prove up the continuity of grades and widths with the aim of turning into new deposits at Epsilon, Pontiac East, Omega, Valdora, and El Sol. Test targets across the property to make new discoveries on the four mineralization types: Cadillac Fault, Skarn/porphyry, Anamaque Sill, and Sigma–Lamaque corridor. These targets were generated last year from a combination of in-house compilation, summer trenching program, and use of Artificial intelligence targeting study by Mira Geoscience.
