Magna Mining Reports High-Grade Copper Results from Levack Mine Drilling

• Drillhole FNX6083-W1 intersected 29.2% copper, 0.9% nickel, and 53.0 g/t precious metals over 1.0 metre
• Intersection located 140 metres down-dip from previous July 2025 results in the Rob's 2 target area
• Mineralization shows similarities to the Morrison Footwall Deposit geology, which was mined until 2019
• Two surface diamond drills currently operating with two underground drills planned for deployment
• Results from electromagnetic surveys confirmed the company's geological interpretation of the area

Magna Mining Inc. (TSXV: NICU) is a Canadian mining company focused on developing nickel, copper, and platinum group metal (PGM) projects, primarily in the Sudbury Region of Ontario. The company operates the McCreedy West Mine and holds a portfolio of properties in the Sudbury mining district. The company acquired the Levack Mine in the first quarter of 2025, adding to its existing properties including Crean Hill, Podolsky, and Shakespeare.

The company's operations centre on the McCreedy West Mine, which is currently in production. Magna Mining's strategy involves continuing production at existing facilities whilst exploring development opportunities across its property portfolio in the Sudbury region.

High-Grade Footwall Mineralization Discovery

Drillhole FNX6083-W1 was designed to test an area 140 metres below drillhole MLV-25-14A, which had previously intersected 2.6% copper, 8.1% nickel and 17.8 g/t platinum plus palladium plus gold over 0.6 metres in July 2025. The new drillhole intersected multiple mineralized intervals ranging from copper-rich chalcopyrite and bornite veinlets to more than one metre of massive chalcopyrite. The highest-grade interval returned 29.2% copper, 0.9% nickel, and 53.0 g/t platinum plus palladium plus gold over 1.0 metre.

The drilling program targeted the footwall environment beneath the No. 3 Zone, following the company's geological interpretation based on structural relationships to the Morrison Deposit. Historical drillhole FNX6083 was deepened to provide a geophysical platform, and survey results from this hole supported the company's interpretation of mineralization in the area. The wedge hole FNX6083-W1 successfully intersected two massive chalcopyrite veins alongside disseminated to stringer copper mineralization.

Magna Mining has designated this target area in the footwall of the No. 3 Zone as the Rob's 2 target. The results include a second significant intersection of 25.5% copper, 1.8% nickel, and 26.3 g/t platinum plus palladium plus gold over 0.5 metres. These intersections represent the company's first drilling results from this specific target area since acquiring the Levack Mine property.

Rob's 2 Target Area Exploration

The Rob's 2 target area is located in the footwall environment between the No. 3 Nickel-Copper Zone and the Morrison Footwall Deposit, approximately 600 metres to the southwest. The Morrison Deposit was discovered by FNX Mining in 2005 and mined until 2019, occurring vertically beneath the No. 7 Contact Zone. Mining operations at Morrison encountered massive sulphide veins varying from less than one metre to more than six metres in thickness.

Dave King, Senior Vice President of Exploration and Geoscience, stated that the results "appear to confirm our belief that the prospective exploration environment at Levack remains under-explored." The drilling targeted subvertical mineralization striking parallel to the Fecunis fault, based on structural relationships observed at the Morrison Deposit. The company reports notable similarities between the geology and vein mineralogy intersected in recent drilling and the upper levels of the Morrison Footwall Deposit.

The Morrison Deposit displayed distinct vertical mineralogical trends, transitioning from nickel-rich pentlandite and pyrrhotite veins in upper levels to copper-rich chalcopyrite veins with increasing precious metal concentrations at depth. The central portion contained chalcopyrite veins up to six metres thick within mineralized areas extending over 250 metres along strike. The mineralogical zonation between nickel-dominated veins in MLV-25-14A and copper-rich veins in FNX6083-W1 follows patterns observed in the Morrison Deposit.

Levack Mine Exploration Program Expansion

Magna Mining is conducting exploration focused on the footwall environment, testing the lateral and down-dip extent of the Rob's 2 target and other Sudbury Breccia units. The program uses downhole geophysical electromagnetic surveys to target drilling within conductive areas of the mineralized system. Two surface diamond drills are currently operating, with one completing infill and metallurgical drilling on the Main Nickel-Copper Zone for the Levack Restart Study.

The second surface drill is exploring the footwall environment between the No. 3 Zone and Morrison Deposit, with an additional wedge hole planned to target areas north of recent intersections. The company has scheduled two underground diamond drills for mobilization within the coming weeks to expand drilling capacity. Underground drilling will provide access to deeper targets beneath existing workings.

The exploration program targets prospective Sudbury Breccia units that may host copper and precious metals-rich footwall deposits similar to others found along the North Range of the Sudbury Basin. Initial drilling on the Rob's 2 target is designed to confirm the geological model and define the extent of mineralization. The company plans to increase drilling activity at Levack over the remainder of 2025 through the addition of underground drilling capacity.

Conclusion and Next Steps

The drilling results from FNX6083-W1 represent the first assays from the Rob's 2 target area since Magna Mining acquired the Levack Mine in early 2025. The company will continue drilling to define the extent of R2 mineralization whilst completing the Levack Restart Study through infill and metallurgical drilling on the Main Zone. Underground diamond drills are scheduled for deployment within the coming weeks to expand exploration capacity and target deeper areas of the footwall environment.
