Results Include 5.0% Cu, 0.7% Ni, and 12.8 g/t Pt+Pd+Au Over 15.2 Metres

Sudbury, Ontario--(Newsfile Corp. - July 8, 2024) - Magna Mining Inc. (TSXV: NICU) (OTCQB: MGMNF) (FSE: 8YD) ("Magna" or the "Company") is pleased to announce additional diamond drilling results and provide an update on the surface advanced exploration bulk sampling in the 109 Footwall (FW) Zone.

Highlights from the new assay results include:

• 109 FW Zone
  MCR-24-087: 5.0 % Cu, 0.7% Ni, 12.8 g/t Pt + Pd + Au over 15.2 metres
  Including, 11.7 % Cu ,1 .0% Ni, 5.8 g/t Pt + Pd + Au over 5.2 metres
  MCB-24-080: 0.6 % Cu, 0.2% Ni, 20.2 g/t Pt + Pd + Au over 15.1 metres
  MCB-24-082: 2.6 % Cu, 0.7% Ni, 13.2 g/t Pt + Pd + Au over 6.4 metres

Jason Jessup, CEO of Magna Mining commented, "The exploration drilling results announced today continue to highlight the high-grade copper and precious metals found in the 109 Footwall Zone. These intersections are within 200 metres of surface and could be incorporated into early test mining. I am also excited to report that we have started the process of extracting the 20,000 tonne surface bulk sample from our 109 Footwall Zone. Our mining contractor, ADLP, (a partnership between Atikameksheng Anishnawbek, Wahnapitae First Nation and Technica Mining) has begun drilling the blast holes, and initial site work is underway to commence dewatering of the underground workings. The Magna operations team, led by our COO Jeff Huffman, has done a fantastic job working with ADLP to perform the risk assessments and planning to ensure seamless and safe execution. We are on track to accomplish our development milestones and growth objectives in the second half of 2024."

The bulk sample work is underway with most of the site preparation completed. (See Image 1 and 2). Blasting is scheduled to commence within the week and mineralized material from the 109 FW Zone will be stockpiled in preparation for trucking to the processing facility later this month. As part of the advanced exploration program, mapping of the fresh rock faces will be completed as mining progresses, providing valuable information on mineralization controls, and reconciliation to the geology model and mineral resource estimate.

The new assays reported today from the Crean Hill diamond drill program include results from eight drillholes targeting the 109 FW Zone. Current drilling is designed to better define the higher-grade core of the 109 FW zone at depth that is within the area that will be developed as part of the underground advanced exploration program. Significant intersections include MCR-24-087 grading 5.0% Cu, 0.7% Ni, 12.8 g/t Pt+Pd+Au over 15.2 metres, including 11.7% Cu, 1.0 % Ni, 5.8 g/t Pt+Pd+Au over 5.2 metres. See Table 1 for full results and Figure 1 for the location of the drilling reported today.

Qualified Person

The 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, Technical Services for Magna Mining Inc. and is a qualified person under Canadian National Instrument 43-101.

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. Samples are then put into plastic bags with 10 bagged samples being placed into rice bags for transport to Swastika Laboratories in Kirkland Lake Ontario via Gardewine Transport 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 lab duplicate.
