Magna Mining Announces Q3 Production Results

Magna Mining announced its Q3 2025 production results from the McCreedy West Mine, its second full quarter operating the asset. The company mined and shipped 75,173 short tons of ore to Vale's Clarabelle mill. The average preliminary grades were 1.52% copper, 0.21% nickel, 0.42 g/t platinum, 0.53 g/t palladium, 0.22 g/t gold, and 10.78 g/t silver. The company also completed 1,796 feet of underground development, highlighting this as a continued focus. Management reiterated its strategy of transitioning from an exploration company to a sustainable mining operator.

This is a routine operational update that provides a mixed picture when analyzed in the context of previous results and guidance.

• Tonnage (Positive): The 75,173 tons produced in Q3 is a 7% increase over the 70,045 tons processed in Q2 2025. This demonstrates a successful ramp-up of mining activities. Furthermore, on July 16, 2025, the company guided for H2 2025 (Q3+Q4) ore sales of 80,000 to 92,000 tons. Shipping 75,173 tons in Q3 alone places the company on track to significantly beat the upper end of its H2 tonnage guidance, which is a strong positive.

• Development (Positive): The 1,796 feet of development in Q3 represents an increase in the daily development rate compared to Q2, where the company saw rates increase from 14.4 ft/day in April to 17 ft/day in June (averaging ~1,500 feet for the quarter). This aligns with the company's stated strategy of prioritizing development to ensure long-term, sustainable production.

• Grade (Negative Concern): The most significant issue is the grade. The company's H2 2025 guidance from July called for a Q3 copper equivalent (CuEq) grade of 2.9% to 3.4%. While the company did not provide a calculated CuEq grade in this release, a rough calculation based on the individual metal grades and previously disclosed metal price assumptions suggests a CuEq grade of approximately 2.4%. This is a clear miss on the guided range and a sequential decline from the 3.26% CuEq grade achieved in Q2. While the company has previously stated it is focused on development, which may involve mining lower-grade material, a miss on specific quarterly grade guidance is a risk flag for a new operator.

Overall Assessment: The news is neutral. The market is likely to view the strong tonnage and development ramp-up positively, as it shows the new team is effectively increasing the mining rate. However, the grade miss is a tangible negative that raises questions about short-term operational forecasting and profitability. The company’s guidance anticipated a significant grade increase in Q4 (3.8% to 4.4% CuEq). The pressure is now on to deliver on that Q4 grade target to validate their mine plan and justify the stock's recent strong performance. Failure to hit the Q4 grade guidance would be a material negative.
