Magna Mining Continues to Intersect High Grade Massive Sulphide Within the Core of the 109 Footwall Zone, Including 2.5% Ni, 9.6% Cu, and 17.4 g/t Pt+Pd+Au over 6.8 Metres

Magna Mining Inc. provide additional drilling results from the 2024 exploration program at Crean Hill, targeting the near surface advanced exploration area of the 109 Footwall (FW) Zone. Recent drilling is designed to define the high-grade core of the 109 FW Zone.

Highlights from the new assay results include:

• 109 FW Zone

MCR-24-068: 0.7% Ni, 2.4 % Cu, 9.7 g/t Pt + Pd + Au over 26.3 metres

Including 3.2% Ni, 11.3 % Cu, 10.6 g/t Pt + Pd + Au over 4.4 metres

MCR-24-069: 0.3% Ni, 0.3 % Cu, 10.7 g/t Pt + Pd + Au over 28.5 metres

Including 0.9% Ni, 0.3 % Cu, 25.3 g/t Pt + Pd + Au over 7.8 metres

MCR-24-070: 1.6% Ni, 5.2 % Cu, 10.0 g/t Pt + Pd + Au over 17.1 metres

Including 2.5% Ni, 9.6 % Cu, 17.4 g/t Pt + Pd + Au over 6.8 metres

“Drilling at Crean Hill has continued to define the high grade, massive sulphide core of the 109 FW Zone, as well as the broader envelope of low sulphide, high precious metal mineralization. Massive sulphide veins continue to demonstrate good continuity, with drillhole intersections grading up to 2.5% Ni, 9.6% Cu and 17.4 g/t Pt + Pd +Au over 6.8 metres, and wider, precious metal intervals up to 0.3% Ni, 0.3 % Cu, 10.7 g/t Pt + Pd + Au over 28.5 metres (Figure 1 and 2). The next phase of near surface drilling on the 109 FW Zone, is designed to extend the strike of the current mineral resource to the south, where historical channel samples indicate low sulphide precious metal mineralization continues within the Sudbury Breccia unit (Figure 1).”

In March 2024, Magna announced the filing of the Crean Hill Closure Plan (see news release) and the signing of the Definitive Offtake Agreement (see news release). As the Company awaits the approval of the final permit required for underground advanced exploration (the Permit to Take Water), these assay results are being incorporated into the design of the test mining program. Due to the relatively shallow depths (approximately 75-125 metres from surface), the drill intersection areas announced in this news release could be incorporated into a test mining plan and executed within 18 months of commencement of the program.

In addition to the 109 FW drilling, one rig continues to complete footwall exploration drilling at Crean Hill. Prospective structures and lithologies including Sudbury Breccia units containing sulphides have been intersected. Several geophysical conductive anomalies have been identified and exploration drilling continues. A summary of Crean Hill assay results is presented in Table 1 and drillhole collars are presented in Table 2.

All lengths are downhole length. True widths are estimated at 85-95% of downhole length.

At Shakespeare, regional drilling is ongoing, and results have been received for the initial five drillholes testing the Palladium Valley target. The Palladium Valley target area is approximately 8.5km northeast of the Shakespeare Mine and consists of several gabbroic intrusive units similar to the Shakespeare gabbro (Figure 3). Magna confirmed the presence of elevated palladium (Brunne-Turcotte), copper and gold (Main Skarn) mineralization at depth beneath historical surface showings (Table 3). These results support the thesis that the lithologies hosting the Shakespeare Deposit are present at Palladium Valley, are mineralized, and have potential to host similar deposits.

The Shakespeare drill rig has since mobilized to the Stumpy Bay area (600m south of the Shakespeare deposit) and is testing coincident ZTEM and Borehole UTEM geophysical conductors identified in 2023. These geophysical anomalies seem associated with known copper and silver mineralization at and near surface.

Magna is fully funded to complete 25,000 metres of exploration drilling in 2024.

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. The core is then logged, and samples marked in intervals of up to 1.5m. All except one Crean Hill drillhole were whole core sampled and the Shakespeare drillholes were cut in half. Samples are then bagged in plastic bags with 10 bagged samples being placed into rice bags for transport to Swastika Laboratories in Kirkland Lake Ontario via Gardewine Transport for Crean Hill samples and Shakespeare samples are transported to AGAT Laboratories in Mississauga Ontario for preparation and analysis. Samples are submitted in batches of 50 with 5 QA/QC samples including, 2 certified reference material standards, 2 samples of blank material and 1 duplicate.
