Magna Mining Intersects 23.2% Copper, 5.6% Nickel, 21.4 g/t Platinum + Palladium + Gold, and 225.0 g/t Silver over 2.4 metres and Provides an Update on Progress at the Levack Mine in Sudbury, Ontario SUDBURY, Ontario, April 14, 2026 (GLOBE NEWSWIRE) -- Magna Mining Inc. (TSXV: NICU) (OTCQX: MGMNF) (FSE: 8YD) (“Magna” or the “Company”) is pleased to provide the results of ongoing exploration and an update on activities at the past-producing Levack Mine, located in the North Range of the Sudbury Basin, Ontario, Canada (Figure 1). Recent drilling has continued to intersect significant copper-rich massive sulphide veins over approximately 175 metres downhole, within the R2 Footwall Zone. Highlights of hole MLV-26-14A W1 are summarized below and in Table 1. Along with the ongoing exploration at Levack Mine, there are several other activities, including underground development, currently underway in anticipation of a restart decision in the second half of 2026. Highlights from the new assay results include: MLV-26-14A W1 23.2% Cu, 5.6% Ni, 21.4 g/t Pt+Pd+Au, 225.0 g/t Ag over 2.4 metres, from 975.9 metres down hole And 10.7% Cu, 1.5% Ni, 14.7 g/t Pt+Pd+Au, 67.1 g/t Ag over 2.1 metres, from 1026.9 metres down hole Including 29.6% Cu, 4.0% Ni, 32.4 g/t Pt+Pd+Au, 181.0 g/t Ag over 0.7 metres, from 1028.3 metres down hole FNX6083-W5 5.7% Cu, 13.7% Ni, 11.2 g/t Pt+Pd+Au, 28.0 g/t Ag over 0.4 metres, from 1117.7 metres down hole Dave King, SVP Exploration and Geoscience at Magna, stated, “Hole MLV-26-14A W1 was drilled to test the subvertical veins along the interpreted eastern margin of the R2 Zone, above and east of drillhole MLV-25-14A, which intersected nickel rich mineralization in the upper levels of the R2 Footwall Zone. The new drillhole intersected multiple copper rich veins over approximately 175 metres downhole, and supports Magna’s structural model and interpreted similarities with the controlling structures within the Morrison Footwall Cu-PGE Deposit. Understanding the structural controls is key to efficiently delineating footwall vein deposits in Sudbury’s North Range and identifying areas where more significant mineralization can occur within thicker vein orientations. We will continue to follow-up on defining and expanding the R2 Zone with our surface and underground diamond drills through the remainder of 2026.” Drilling results reported today are related to Magna’s ongoing exploration program at the Levack Mine, and include new assays from drillhole MLV-26-14A W1, as well as additional assays results from drillhole FNX-6083 W5 received since the initial results were released in February 2026 (see Figure 2 and news release dated February 18, 2026). Complete assay results from these two drillholes are summarized in Table 1. Drillhole MLV-26-14A W1 was designed to better define the eastern margin of the R2 Footwall Zone, along an interpreted north-south mineralized bounding structure. At the Morrison Deposit, located 600 metres to the southwest, more significant massive sulphide veins up several metres thick often occur in the extensional environment between the north-south striking bounding structures that contain narrower mineralized veins (Figure 3). The mineralization in the R2 Footwall Zone may have similar controls, as demonstrated by the multiple veins encountered in drillhole MLV-26-14A W1 with downhole widths ranging from 0.7 – 2.4 metres. Based on our understanding of the Morrison Deposit model, ongoing drilling at Levack will continue to define the mineralized north-south striking structures and explore for potential thicker east-west veins from both surface and underground drilling platforms. A follow up surface drillhole is now underway to test what is interpreted to be the extensional environment at the R2 Footwall Zone approximately 25-30 metres west of the intercepts in drillhole MLV-26-14A W1. In addition, underground drilling to test the R2 Footwall Zone from more optimal orientations has now commenced from the 8451 drill bay on the 1800 Level (Figure 4). Levack Mine personnel are also re-establishing shaft levels above the 1800 Level and rehabilitating along the 1600 Level and 2650 Level from the No. 2 shaft towards the No. 3 shaft at the eastern extent of the Levack property. These levels will provide additional underground exploration diamond drilling platforms to test areas that are challenging to drill from surface. Once available, a diamond drill will be mobilized to the 2650 Level near the No. 3 shaft to define the upper R2 Footwall Zone and test additional target areas within the footwall of the No. 3 OB.
