Magna Mining Reports 17.9% Cu, 0.6% Ni and 28.1 g/t Pt + Pd + Au over 1.8 Metres in the 700 Footwall Copper Zone at McCreedy West Mine

Magna Mining Inc. (TSX-V: NICU) (OTCQX: MGMNF) (FSE: 8YD) is pleased to announce additional drill results from the McCreedy West mine. The results include high grade copper, nickel and precious metal intersections from an area located in the footwall, up-dip within the main 700 Cu-PGE Footwall Zone (“700 Zone”) and within 150 metres of surface. The reported holes (Table 1) were drilled in support of production planning and potential production expansion into areas where narrow vein mining methods could be applied. Mineralization in this area contains high PGE grades hosted in copper and nickel rich veins. Intersections include 17.9% Cu, 0.6% Ni, 28.1 g/t Pt + Pd + Au over 1.8 metres in drillhole MMW-25-119 and 10.5% Cu, 8.3% Ni, 42.6 g/t Pt + Pd + Au over 0.3 metres in drillhole MMW-25-133 (Table 1).

Highlights from the new assay results include:

MMW-25-118: 4.9% Cu, 1.0% Ni, 2.9 g/t Pt + Pd + Au over 1.5 metres

And 10.4% Cu, 0.5% Ni, 16.1 g/t Pt + Pd + Au over 0.9 metres

MMW-25-119: 1.5% Cu, 0.4% Ni, 1.3 g/t Pt + Pd + Au over 7.3 metres

And 1.7% Cu, 0.7% Ni, 4.0 g/t Pt + Pd + Au over 10.5 metres

And 17.9% Cu, 0.6% Ni, 28.1g/t Pt + Pd + Au over 1.8 metres

MMW-25-133: 10.5% Cu, 8.3% Ni, 42.6 g/t Pt + Pd + Au over 0.3 metres

Mynyr Hoxha, VP Mines Geology, stated: “The diamond drilling at the McCreedy West mine continues to yield excellent copper and precious metal grades, and is focused on defining near-term production as well as expanding the 700 Zone up-dip and to the east and west. The data we are gathering from this drilling will be instrumental in guiding our development ore headings, optimizing mining stope designs and maximizing ore grade. These narrow, massive sulphide veins, containing platinum, palladium and gold, found along the footwall of the 700 Zone can be incorporated into our mine plan and provide an opportunity for selective mining of high margin ore in 2026. In addition, the new access being developed on the western side of the 700 Zone will enable diamond drilling access to targets that were previously inaccessible from existing mine workings. This is an exciting exploration initiative that is anticipated to commence later this year.”

McCreedy West Diamond Drilling

The underground diamond drilling program at the McCreedy West mine is supported by two drills and is currently focused on definition and expansion drilling in the 700 Zone. Additional diamond drilling assays received since the news release dated June 10, 2025 are summarized in Table 1 and drillhole collar information is presented in Table 2. At McCreedy West, definition drilling with one drill continues to support near to mid-term production, with infill drilling designed to facilitate detailed stope design and optimize production grade. The second drill has begun definition and expansion drilling in areas not currently considered in the mine plan. Initial drilling on the 590 Level is focused on defining high-grade mineralization within the footwall side of the 700 Zone (Figures 2 and 3). At McCreedy West, precious metal grades appear to increase as a function of the distance into the footwall from the SIC contact. Drilling in this area has intersected massive sulphide veins with high precious metal grades up to 42.6 g/t Pt + Pd + Au over 0.3 meters and 28.1 g/t Pt + Pd + Au over 1.8 meters in drillholes MMW-25-133 and MMW-25-119 respectively. These high-grade Cu-PGE veins have the potential to be developed with more selective mining methods and could provide a source of high margin ore in 2026. This area remains open for potential expansion both up-dip and along strike to the east and west. Development on the 930 Level required to establish new diamond drilling platforms is progressing on schedule and Magna expects to be drilling on the western side of the 700 Zone (Figure 2) later this year. The western margin of the known 700 Zone is not well defined and has been identified as a high priority exploration target. There is potential to expand the 700 Zone mineralization west towards the adjacent past producing Hardy/Boundary deposit.

Qualified Person for Technical Information

The scientific and technical information in this press release has been reviewed and approved by David King, M.Sc., P.Geo. Mr. King is the Senior Vice President, Exploration and Geoscience for the Company and is a qualified person under National Instrument 43-101.

Quality Assurance and Control

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 1.5m. Levack drill core is split and sampled ½ 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, Ontario for preparation, which are then shipped to Lakefield, Ontario for analysis. Samples are submitted in batches of 50 with 4 QA/QC samples including, 2 certified reference material standards and 2 samples of blank material.
