O3 Mining Completes Positive Infill Drilling Program at Marban Project

Feb 1, 2022


"The drilling results reported from the 2021 infill drilling program have confirmed the significance of the Marban, Kierens, Norlartic, North and North North Preliminary Economic Assessment ("PEA") Pits," O3 Mining's President and Chief Executive Officer, Mr. Jose Vizquerra said.

"The infill drilling program at Marban has continuously demonstrated structural continuity and expansion of mineralization in both open pit and underground mine scenarios. The drill holes reported today reconfirm our expectations of expanding the gold resource in the open pits at Marban and allow us to focus on providing a resource update in the coming months. Throughout 2022, activity at Marban will be focused on Marban Engineering, undertaking the completion of the Marban Pre-Feasibility Study ("PFS") and future economic studies, as well as focusing on the Marban Regional greenfield exploration program."

O3 Mining Inc. provided an update on its fully-funded large-scale drilling program at its Marban and Alpha properties in Val-d'Or, Québec, Canada, which seeks to convert, expand, and discover new gold resources. The Corporation is reporting the completion of its infill drilling program at the Marban project and reporting results from 12 holes drilled in and around the Marban project's open-pittable deposits.

The Marban zone drilling highlights consist of an array of veins and veinlets composed of quartz, calcite, and chlorite within a folded basaltic unit. The Norlartic zone drilling highlights consist of a stockwork of quartz veinlets with disseminated pyrite within intermediate and mafic dykes as well as a basaltic unit within the hanging wall of the Norbenite Shear. This geology is consistent with the description of the mineralized zones of the historical mines in and around the Marban project. Many drill holes published today have crossed historical mining stopes and confirm the presence of high-grade material within the mining walls and wide envelopes on both sides of those mine openings.

A portion of the 2021 drilling program was designed to convert a significant proportion of the in-pit Marban resources of the inferred category into the indicated category. All intercepts listed in today's news release are part of this program.  All results from the infill drilling program in 2021 will be included in an updated resource for Marban, which is to be completed by an independent contractor. The contractor has received all the inputs required from O3 Mining and is expected to be released during the first quarter of 2022.
