Magna Mining Continues to Intersect Copper and Precious Metal Bearing Veins in Multiple Drill Holes at Levack Mine’s R2 Target in Sudbury, Including 25.0% Copper, 34.7 g/t Pt+Pd+Au, and 151 g/t Silver over 0.4 metres SUDBURY, Ontario, Dec. 09, 2025 (GLOBE NEWSWIRE) -- Magna Mining Inc. (TSXV: NICU) (OTCQX: MGMNF) (FSE: 8YD) (“Magna” or the “Company”) is pleased to provide an update on exploration activities and assay results from ongoing exploration at the past-producing Levack Mine, located in the North Range of the Sudbury Basin, northeastern Ontario, Canada (Figure 1). Today’s release incorporates the results from four diamond drill holes which tested the R2 target, with all four holes intersecting multiple veins containing high grade copper (“Cu”) and precious metals, including platinum (“Pt”), palladium (“Pd”), gold (“Au), and silver (“Ag”). Mineralization within the R2 target area has now been intersected over a vertical extent of greater than 200 metres and remains open up-dip towards the No. 3 Footwall Zone and at depth and to the west towards the Morrison Footwall Cu-PGE Deposit. Highlights from the new assay results include: • FNX6083-W3 12.9% Cu, 140.7 g/t Pt+Pd+Au and 78.0 g/t Ag over 0.3 metres, from 955.7 metres down hole And 18.6% Cu, 38.5 g/t Pt+Pd+Au and 105.0 g/t Ag over 0.6 metres, from 1,027.1 metres down hole • FNX6083-W4 12.3% Cu, 22.2 g/t Pt+Pd+Au and 78.9 g/t Ag over 1.3 metres, from 1,211.2 metres down hole • FNX2026-W1 4.5% Cu, 12.4 g/t Pt+Pd+Au and 30.0 g/t Ag over 0.3 metres, from 1,096.7 metres down hole • FNX2026-W2 24.8% Cu, 26.3 g/t Pt+Pd+Au and 153.0 g/t Ag over 0.3 metres, from 1,069.4 metres down hole And 25.0% Cu, 34.7 g/t Pt+Pd+Au and 151.0 g/t Ag over 0.4 metres, from 1,083.4 metres down hole Dave King, SVP Exploration and Geoscience stated, “Diamond drilling on the R2 exploration target has continued to intersect multiple high-grade copper and precious metal veins, and further our understanding of the footwall breccias and the geological controls on sulphide veining. Although the individual vein intersections reported today are narrow, we continue to believe the R2 mineralization is part of a regionally significant footwall Cu-precious metals system centered near the Fecunis fault. The R2 mineralization may be associated with the Levack No. 3 Footwall Zone and the Morrison Footwall Cu-PGE Deposit, as well as other known footwall Cu-precious metals deposits located on the east side of the Fecunis fault. Given the optimal geological conditions, footwall veins can thicken quickly over short distances resulting in significant sulphide concentrations. We continue to focus our exploration efforts on defining and extending mineralization at the R2 target, as well as exploring for other, new Cu-precious metals footwall systems at Levack.” The four diamond drill holes in today’s press release were designed to test the depth potential of the R2 target area below the mineralization intersected in previously released holes FNX6038-W1 and FNX6038-W2 (see news releases dated August 28, 2025 and October 23, 2025 ). Drillholes FNX6083-W4 and FNX6083-W3 are additional wedge holes drilled from the same surface drill hole platform and were successful in extending the mineralization at depth by 25 metres and 75 metres below FNX6083-W1, respectively. Of note, drillhole FNX6038-W3 encountered a total of nine mineralized intervals between 930 metres and 1,207 metres down hole, with intercepts ranging from 0.3 metres to 3.2 metres and including 18.6% Cu, 15.4 g/t Au, 20.0 g/t Pd, 3.0 g/t Pt, and 105 g/t Ag over 0.6 metres. Drillhole FNX6083-W4 encountered two closely spaced veins which returned 12.3% Cu, 1.3% Ni, 6.7 g/t Pt, 13.9 g/t Pd, 1.6 g/t Au, and 78.9 g/t Ag over 1.3 metres. Drillholes FNX2026-W1 and FNX2026-W2 are wedge holes drilled from another historical surface drill platform and designed to investigate the R2 target via a different orientation (Figure 3). Drillhole FNX2026-W1 encountered six mineralized intervals approximately 25 metres to the southwest of FNX6038-W3, characterized by lower grade copper results relative to other R2 drillholes but impressive precious metals grades, including 4.5% Cu, 0.5% Ni, 3.4 g/t Pt, 6.5 g/t Pd, 2.5 g/t Au, and 30.0 g/t silver over 0.3 metres. These intercepts are currently interpreted to represent a different vein orientation than the veins identified elsewhere in the R2 target. Drillhole FNX2026-W2 targeted beneath FNX6083-W1 from a different orientation, and encountered four high grade veins over a 35 metre interval, each of which showed strong enrichment in copper and precious metals, such as 25.4% Cu, 4.7 g/t Pt, 16.8 g/t Pd, 0.4 g/t Au, and 185 g/t Ag over 0.4 metres, as well as 25.0% Cu, 15.3 g/t Pt, 14.7 g/t Pd, 4.8 g/t Au, and 151 g/t Ag over 0.4 metres. The mineralized veins in the R2 target area are characterized by high-grade precious metals values, similar to those observed at the Morrison Footwall Cu-PGE deposit, located 600 metr
