O3 Mining's President and Chief Executive Officer, Mr. José Vizquerra commented: "We are pleased to announce the receipt of the final assay results from our infill drilling campaign at Malartic H, completed earlier this year. These results mark the third and final set of assays, following the initial results on April 17, 2024, and the second set of results on July 18, 2024. With the completion of this campaign and the full compilation of assay data, we are now positioned to work on a mineral resource estimate as we focus on upgrading the current inferred resource to the measured and/or indicated categories. We are proud of the progress made at Malartic H, which continues to reinforce our confidence in the strength of the Marban Alliance project and the strategic value Malartic H brings to it."

The objective of the 2024 drilling campaign on the Malartic H deposit is to upgrade mineral resources that are currently classified as inferred mineral resources in the Corporation's current mineral resource estimate to the indicated mineral resource category (see news release of O3 Mining dated June 20, 2023 and entitled "O3 Mining Delivers Maiden Mineral Resource Estimate for Malartic H"). The 2024 drilling campaign totaled 143 drill holes of which assay results for 45 drill holes are being reported today (all results received). The results for 56 and then 42 drill holes were previously reported (see news release of O3 Mining dated April 17, 2024, entitled "O3 Mining Intersects 119.1 g7/t Au over 2.5 Metres at Malartic H, Marban Alliance and the news release of O3 Mining dated July 18, 2024, entitled "O3 Mining Intersects 102.0 g/t Au over 1.5 Metres at Malartic H, Marban Alliance").
