O3 Mining Intersects 20.5 g/t Au over 2.2 Metres Including 73.5 g/t Au over 0.6 Metres at Hygrade Fold, Marban Engineering
O3 Mining Inc. (OTCQX: OIIIF) has announced initial results from its 10,500-metre drilling campaign at the Hygrade Fold area, Val-d'Or, Quebec. Noteworthy intercepts include 5.7 g/t Au over 7.6 metres and 20.5 g/t Au over 2.2 metres, indicating significant exploration potential. The region contains historical mines with over 40,000 oz Au produced. A recent pre-feasibility study indicated a robust project, with an NPV of C$463M and an IRR of 23.2%. Further exploration is planned for winter 2023.
- High-grade gold intercepts: 5.7 g/t over 7.6m and 20.5 g/t over 2.2m.
- Pre-feasibility study shows C$463M NPV at 5% and 23.2% IRR.
- Significant historical production (40,000 oz Au) in Hygrade area.
- Plans for continued exploration and drilling in winter 2023.
- None.
TORONTO, Sept. 13, 2022 /PRNewswire/ - O3 Mining Inc. (TSXV: OIII) (OTCQX: OIIIF) ("O3 Mining" or the "Corporation) is pleased to announce it has received initial results from its 10,500 metre drilling campaign on the Hygrade Fold area, within Marban Engineering in Val-d'Or, Quebec, Canada.
- 5.7 g/t Au over 7.6 metres in hole O3MA-22-341, including 30.9 g/t Au over 1.2 metres, within highly biotized ultramafic intrusion, with mineralization related to quartz veining containing visible gold
- 20.5 g/t Au over 2.2 metres in hole O3MA-22-351, including 73.5 g/t Au over 0.6 metres, within a sheared komatiitite, related to a felsic dike, with quartz veining and visible gold
O3 Mining's President and Chief Executive Officer, Mr. Jose Vizquerra commented, "We are very excited with the initial results from our exploration work at the Hygrade Fold area in the northwestern portion of Marban Engineering, as part of our brownfield exploration program. This underexplored, large land package offers significant exploration potential upside, with several historic showings, and promise for a new discovery. With our recent positive pre-feasibility study results (C
O3 Mining initiated a brownfield exploration program from late June to early September, drilling 10,500 metres within the Hygrade Fold area. This area encompasses two former mines, the Malartic Hygrade mine and the Orion #8 mine, which produced 40,000 oz Au over their mine life (historical production summarized in Table 2). The Hygrade Fold area also includes the Malartic H deposit, which is composed of several stacked zones hosted in basalt and felsic dikes, which has never been mined.
The compilation of historical drilling in this area revealed a previously underexplored sector with high-grade historic intercepts within wide basaltic units similar to the basalt hosting the Marban deposit. Assay results for 6,500 samples are still pending within the Hygrade Fold area. The summer drilling campaign confirmed the presence of a mineralized structure within the basaltic units and the Corporation plans to follow up drilling for the 2023 winter campaign on best intercepts as results are being received. The winter campaign will also aim to better define and expand known mineralization at Malartic H, Malartic Hygrade and Orion #8.
