Magna Mining Reports Mineral Resource Estimate for the Levack Mine in Sudbury, Ontario
None
On November 18, 2025, Magna Mining announced its initial Mineral Resource Estimate (MRE) for its flagship development project, the Levack Mine in Sudbury, Ontario.
Key highlights of the MRE include: - Indicated Resources: 6.1 million tonnes at a grade of 3.54% Copper Equivalent (CuEq). - Inferred Resources: 5.2 million tonnes at a grade of 3.60% CuEq. - High-Grade Footwall Deposits: The resource includes exceptionally high-grade zones, notably the Morrison Footwall with 178,000 Indicated tonnes at 15.5% CuEq and the No. 3 Footwall with 76,000 Inferred tonnes at 13.4% CuEq.
The company plans to award a contract for a Preliminary Economic Assessment (PEA) by the end of 2025, with completion expected in 2026. Magna is also working to re-establish hoisting capabilities at the site, targeting a potential start in Q1 2026. CEO Jason Jessup stated the MRE results "exceeded our expectations."
The release of an initial MRE is a significant de-risking milestone and a fundamental value driver for any development-stage mining company. This news is material and positive as it confirms a substantial and high-grade resource at Magna's flagship Levack project, validating the company's acquisition strategy.
Reviewing the historical news provides essential context: - Transition to Producer (Q1 2025): Magna transformed its business by acquiring a portfolio of Sudbury assets from KGHM, including the producing McCreedy West mine and the past-producing Levack mine. This was funded by a $33.5 million financing in March (partially convertible debt at a $2.00 conversion price). - Operational Ramp-up at McCreedy West: The first full quarter of production (Q2 2025) resulted in a negative cash margin and free cash outflow of $10.7 million, as the company invested heavily in underground development to optimize the mine. Guidance issued in July for H2 2025 projected significantly improved grades and costs in Q4 versus Q3. However, Q3 production results from October 22 showed an average grade that appears to be below the guided range for Q3, raising questions about the ramp-up timeline and profitability of this asset. - Exploration Success at Levack: Throughout 2025, the company consistently released high-grade drill results from Levack (e.g., 29.2% Cu over 1m on Aug 28; 24.0% Cu over 2.0m on Apr 30), building confidence and anticipation for a formal resource estimate. - Strengthened Treasury (Q3 2025): The company raised an additional $50 million in September via a private placement priced at $2.40 per share, significantly higher than the March financing price. This demonstrates strong market support and fully funds the company's near-term plans.
The November 18 MRE is the successful culmination of the 2025 Levack exploration program. It provides a solid, independently verified foundation for the upcoming PEA and future economic studies. The high grades, particularly in the footwall zones, confirm the asset's quality and potential for high-margin production. This positive development provides a clear path forward for Levack and helps shift the investment narrative toward a major, high-grade development project, balancing concerns over the ongoing cash burn and operational challenges at the McCreedy West mine. The MRE exceeded management's expectations and solidifies Levack as the cornerstone asset for the company's future growth.
Magna Mining Inc. is a Canadian mining company focused on acquiring, exploring, and developing nickel, copper, and precious metal properties in the Sudbury Basin, Ontario. In February 2025, the company transformed from an explorer to a producer by acquiring a portfolio of assets from KGHM, including the currently producing McCreedy West Mine.
The company's flagship development project is the past-producing Levack Mine. The initial Mineral Resource Estimate for Levack, announced November 18, 2025, confirms a large, high-grade deposit with 6.1M tonnes Indicated at 3.5% CuEq and 5.2M tonnes Inferred at 3.6% CuEq. The company's strategy is to become a significant Sudbury-focused producer by restarting its portfolio of permitted, past-producing mines.
