Magna Mining Provides Update on the Surface Advanced Exploration Bulk Sampling Program at the Crean Hill Project and Corporate Update

Sudbury, Ontario--(Newsfile Corp. - October 7, 2024) - Magna Mining Inc. (TSXV: NICU) (OTCQB: MGMNF) (FSE: 8YD) ("Magna" or the "Company") is pleased to provide an update on the advanced exploration surface bulk sample at the Crean Hill Project in Sudbury, Ontario.

Jeff Huffman, COO of Magna Mining commented, "Magna has successfully completed the surface bulk sample program and acquired much of the data required to fully assess the base case metallurgical performance of the 109 Footwall ("FW") Zone. Additional testing is being completed on samples collected during the program and will be used to advise future test work. The sample was taken across the entire width of the mineralized zone, including the higher sulphide core of the deposit and the low-sulphide, higher PGM extremities. We are pleased with the results, and they are in line with our predictions on grade and dilution (both external and internal). This reconciliation will be used to design future test mining stopes in our underground advanced exploration program."

The mining of the surface bulk sample commenced on July 2, 2024, and processing through the Sudbury Integrated Nickel Operations' ("Glencore") Strathcona Mill was completed on September 7, 2024. A total of 20,524 dry tonnes of feed (see Table 1) from the 109 FW Zone was processed over a 5-day period. Concentrate was produced which will be processed through Glencore's Falconbridge Smelter. The project was executed on time and the initial objectives of the program have been achieved, including:

• Magna providing 20,524 tonnes of 109 FW Zone mineralization, sufficient to process over a 5-day period and achieve steady state operation of the plant.
• Variable concentrate grades produced allowing for evaluation of recovery performance at various concentrate grades.
• Successful sampling of material throughout the process plant, which will allow future test work designed to optimize performance of this style of mineralization and improve recoveries of base and precious metals.
• Reconciliation to the estimated tonnes and grade mined, based on the current resource model and assumptions on mining dilution.
