Magna Mining drills 28 m of 2.3% Ni, 0.7% Cu at Levack

Mr. Jason Jessup reports MAGNA MINING INTERSECTS NEAR SURFACE CONTACT NICKEL MINERALIZATION GRADING 2.3% NI, 0.7% CU OVER 28.0 METRES AT THE LEVACK MINE Magna Mining Inc. has provided an update on exploration activities and assay results from the continuing exploration at the Levack mine. Results include the initial assays from the near-surface portion of the No. 1 nickel-copper (Ni-Cu) zone, supporting the Levack mine restart study. Highlights from the new assay results include: MLV-25-21: 2.3 per cent Ni, 0.7 per cent Cu, and 0.3 gram per tonne (g/t) platinum (Pt) plus palladium (Pd) plus gold (Au) over 28.0 metres; Including 6.6 per cent Ni, 0.7 per cent Cu, and 0.6 g/t Pt plus Pd plus Au over 2.4 metres; And 3.3 per cent Ni, 1.0 per cent Cu, and 0.5 g/t Pt plus Pd plus Au over 12.4 metres; MLV-25-22: 2.4 per cent Ni, 0.8 per cent Cu, and 0.3 g/t Pt plus Pd plus Au over 15.5 metres; And 3.2 per cent Ni, 2.2 per cent Cu, and 1.4 g/t Pt plus Pd plus Au over 1.9 metres. Dave King, senior vice-president of exploration and geoscience, stated: "We are pleased to announce initial assay results from the near-surface drilling on the No. 1 contact Ni-Cu zones at the Levack mine. Drilling in this area will provide the data required to advance the Levack restart study and provide appropriate drill density to support the higher level of geological confidence required for our upcoming mineral resource estimate. In addition to the Keel copper-PGE (Cu-PGE) zone, initial mining from this zone could be accessed via a new ramp from surface. The intersections reported today are approximately 135 to 155 metres from surface and confirm Magna's belief that there are significant areas of wide, high-grade nickel mineralization at shallow depths remaining at the Levack mine." Diamond drilling and exploration plan There are currently two surface diamond drills operating at the Levack mine, one completing near-surface infill and metallurgical drill holes on the No. 1 and No. 2, and main zones, and a second drill exploring the footwall environment between the No. 3 Ni-Cu zone and the Morrison Cu-PGE (platinum group element) deposit. The first drill has completed a number of holes in the No. 1 and No. 2 zones, and is currently testing an area to the east of the main OB, to expand on known Ni-Cu mineralization, which locally tends to have higher precious metals and could potentially be accessed early in a mine restart plan. Once this drilling is completed, it is expected that this drill will also transition to testing the footwall area below the No. 3 OB, where the second diamond drill has been exploring for the past two months. Here, the second drill is currently drilling a wedge hole to test approximately 150 metres below the intersection in hole MLV-25-14A, which graded 2.6 per cent Cu, 8.1 per cent Ni, and 17.8 g/t Pt plus Pd plus Au over 0.6 metre (reported on July 9, 2025). Since releasing the results of MLV-25-14A, a historical drill hole, FNX6083, was extended to provide a geophysical platform hole and a wedge off hole FNX6083 has been completed based on the results of the geophysical survey. Assay results for these holes are pending and are expected to be released in the coming weeks. In addition to the surface diamond drills, an underground diamond drill will begin drilling at the Levack mine within the current quarter and a second underground diamond drill is expected to begin drilling in Q4 (fourth quarter). These drills will be focused on testing the area farther downdip and on strike of the area below the No. 3 zone, as well as following up on the east side of the Fecunis fault, where historical hole FNX21200 intersected 33.4 per cent Cu, 0.9 per cent Ni, and 23.9 g/t Pt plus Pd plus Au over 0.2 metre. This area is interpreted as potentially having a vertical vein system, subparallel to the Fecunis fault. The intersection in FNX21200 is open in all directions. The footwall copper systems in the north range of the Sudbury basin commonly have a thicker (two to 10 metres) massive sulphide veins in the central core, with sulphide veins narrowing along strike, near the margins of the deposit. The company is encouraged by the potential in this area and will be planning follow-up exploration once underground drilling is under way. The drilling reported from the Keel Cu-PGE zone targeted the extensions of the known mineralization and areas in proximity to a conceptual ramp design to aid in detailed planning and support of the restart study for the Levack mine. Assays are summarized in table 1 and drill hole collar information is presented in table 2. Qualified person for technical information The scientific and technical information in this news release has been reviewed and approved by David King, MSc, PGeo. Mr. King is the senior vice-president, exploration and geoscience, for Magna Mining and is a qualified person under National Instrument 43-101. Quality assurance and quality control (QA/QC) Sample QA/QC procedures for Magna have been designed to meet or exceed industry standards. Drill core is collected from the diamond drill and placed in sealed core trays for transport to Magna's core facilities. Levack drilling utilizes NQ-sized core and McCreedy West utilizes BQTK-sized core. The core is then logged and samples marked in intervals of up to 1.5 metres. Levack drill core is split and sampled one-half core, and McCreedy West is whole core sampled. Samples are then put into plastic bags, with 10 bagged samples being placed into rice bags for transport to SGS Laboratories in Garson, Ont., for preparation, which are then shipped to Lakefield, Ont., for analysis. Samples are submitted in batches of 50 with four QA/QC samples, including two certified reference material standards and two samples of blank material. About Magna Mining Inc.
