TSXV:OIII | OTCQX:OIIIF – O3 Mining

TORONTO, Oct. 30, 2024 /PRNewswire/ – O3 Mining Inc. (TSXV: OIII) (OTCQX: OIIIF) (“O3 Mining” or the “Corporation“) announces that it will be completing a preliminary economic assessment (“PEA“) on the Corporation’s flagship Marban Alliance project in Val-d’Or, Québec (“Marban Alliance“). The Corporation has engaged G Mining Services Inc. as the lead consultant for the PEA, which will be prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects. O3 Mining expects that results from the PEA will be available in the fourth quarter of 2024. These results are expected to highlight the advancements made on Marban Alliance since the effective date of the current Prefeasibility study (being August 24, 2022) and provide updated guidance for use in a Feasibility Study on the Marban Alliance Project that is expected to commence in early 2025. In addition, the Corporation is expecting the environmental baseline studies to be completed in the first quarter of 2025 following comprehensive field work gathered over a period of three years. Assuming positive results, the Corporation intends to commence Impact Studies in second quarter of 2025.

O3 Mining’s President and Chief Executive Officer, Mr. José Vizquerra commented: “Since the publication of the Marban Alliance prefeasibility study in 2022, our technical team has been committed to improving and optimizing the mining project. This includes, among others, optimizations to our mining and processing parameters, inclusion of additional resources from resource conversion of current pits, as well as new satellite deposits such as Malartic H. This PEA will provide an updated picture of the merits of developing the Marban Alliance project and provide insights on the Feasibility Study expected to be completed in the second half of 2025. Additionally, we have made progress on our environmental and permitting processes, with the baseline study in its final stage, which will allow us to initiate our Impact Studies in parallel with the Feasibility Study. We will continue to develop the Marban Alliance project by focusing on win-win opportunities for our partners, host communities, and shareholders. To that end, we are committed to developing the Marban Alliance project on a sustainable basis for local and regional stakeholders. With this in mind, O3 Mining is well-positioned to benefit from de-risking the Marban Alliance project while remaining flexible on evaluating options in the development due to the location of our project in Val-d’Or among existing processing facilities.”
