Magna Mining Intersects 25.8% High-Grade Copper Mineralization at Levack Mine

en.Wedoany.com Reported - On November 12, Canadian mining company Magna Mining announced new drilling results and restart engineering progress at its Levack Mine in the Sudbury Basin, Ontario. The latest drilling identified a high-grade mineralized interval grading up to 25.8% copper and 3.6% nickel over 0.7 metres in the R2 Footwall mineralized zone. The company is simultaneously advancing underground drift extension, drill platform construction and mine hoisting system upgrades, and plans to carry out ore production ahead of commercial production in 2027.

This round of exploration focused on the R2 Footwall mineralized zone, the Intermediate Orebody, and previously undefined copper and platinum group metal (PGM) mineralized areas. Drill hole MLV-26-80 intersected 3.9 metres grading 5.6% copper, 0.9% nickel, 4.4 g/t combined platinum, palladium and gold, and 34 g/t silver, for a copper equivalent grade of 7.9%. Within this interval, a 0.7-metre section graded 25.8% copper, 3.6% nickel and 33.3% copper equivalent.

Another drill hole, MLV-26-81, intersected 1.3 metres in the R2 mineralized zone grading 13.7% copper, 2.9% nickel, 8.4 g/t combined platinum, palladium and gold, and 82.1 g/t silver, for a copper equivalent grade of 19.6%. In addition, MLV-26-80 intersected a previously undefined footwall mineralized interval approximately 260 metres from the R2 target, grading 9.7% copper, 0.6% nickel and 19.3 g/t combined platinum, palladium and gold over 2.2 metres, for a copper equivalent grade of 16.6%. These results require follow-up drilling to determine the continuity, geometry and resource potential of the mineralized bodies.

The company is constructing a ramp connecting the 1800 level and the 1600 level to provide access to the Intermediate Orebody and to create working faces for subsequent infill drilling and mine design. During construction, sulfide mineralization was encountered over an approximately 12-metre section of the ramp, with a single muck pile sample assaying 5.7% copper, 8.4 g/t platinum, 1.0 g/t palladium and 0.3 g/t gold. Underground drilling has been arranged to further determine the relationship between this mineralized interval and the Intermediate Orebody.

Drilling equipment has transitioned from surface operations to underground construction. Three diamond drill rigs are currently operating underground, and a fourth rig has arrived at the 2650 level and will drill from a recently rehabilitated drift. The company also plans to resume development of the 2950 level exploration drift in early December, advancing the working face approximately 200 metres toward the R2 Footwall mineralized zone, reducing the distance to the target mineralized body from the current approximately 300 metres to approximately 100 metres, thereby shortening subsequent resource definition drill holes.

In addition, Magna has decided to integrate the Levack Mine with the adjacent and underground-connected McCreedy West Mine into the Levack Mining Complex, sharing technical, maintenance and certain surface management resources. The integration of the two mines will adopt unified technical and maintenance management arrangements, while resource evaluation and mining plans for each orebody will still be carried out separately.

The Levack Mine is located in the North Range of the Sudbury Basin, Ontario, Canada, and is a former underground producer of copper, nickel and platinum group metals. Magna announced the preliminary economic assessment results for the mine in October 2026 and received board approval to proceed with the restart. Current work priorities have gradually shifted from resource exploration to underground access construction, equipment restoration and production preparation, with ore production ahead of commercial production planned for 2027.
