Magna Mining Provides an Update on Advanced Exploration at the Crean Hill Project and Corporate Update

Sudbury, Ontario–(Newsfile Corp. – September 5, 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.

The mining of the surface bulk sample commenced on July 2, 2024, and the final blast was on August 15, 2024. A total of 20,714 tonnes of rock was excavated, crushed and hauled to Glencore Sudbury Integrated Nickel Operations’ (“Glencore”) Strathcona Mill, with the last truck arriving on August 29, 2024. The project was executed on time and to the planned design. Three 8-metre-high benches were extracted from the 109 Footwall Zone, with routine grab samples taken from each truckload that was hauled to the stockpile. Mapping was completed on each bench to identify mineralized trends and structures. This information will be used to better understand this mineralized zone and design mining stopes for the underground portion of the advanced exploration program. The milling of the ore commenced on September 2, 2024, and is scheduled to be completed on September 6, 2024. The bulk sample will be processed separately through the Strathcona Mill with samples taken from various parts of the circuit to evaluate and improve metallurgical performance, enhance recoveries and reconcile against our resource estimate.

Jason Jessup, CEO of Magna Mining commented, “Magna, working with ADLP as the mining contractor and Z’Gamok as our crushing and haulage contractor, have executed the surface bulk sample work on time and on budget, while slightly exceeding our original designed bulk sample tonnage. We observed semi-massive and massive sulphides throughout the sample and initial grab samples are reconciling well to our internal grade estimates. The bulk sample program on site was conducted without any environmental issues or injuries. The next phase of the surface bulk sample is underway as Glencore is processing this material through their mill this week. We will expect to have assays for the bulk sample ready to announce within the next 4 – 6 weeks.”

Magna has also initiated dewatering of the underground workings. The current system is temporary while the long-term dewatering system and infrastructure designs are finalized. This initial dewatering will provide data and information to better plan and implement our long-term dewatering strategy.
