Magna Mining Reports Diamond Drilling Results from the 109 Footwall Zone Surface Bulk Sample Area

Sudbury, Ontario–(Newsfile Corp. – May 8, 2024) – Magna Mining Inc. (TSXV: NICU) (OTCQB: MGMNF) (FSE: 8YD) (“Magna” or the “Company”) is pleased to provide additional diamond drilling results from the 2024 exploration program at Crean Hill, targeting the near surface advanced exploration area of the 109 Footwall (FW) Zone.

Highlights from the new assay results include:

• 109 FW Zone

MCB-24-029: 0.9% Ni, 2.9 % Cu, 9.5 g/t Pt + Pd + Au over 6.3 metres

MCB-24-031: 0.7% Ni, 0.8 % Cu, 6.8 g/t Pt + Pd + Au over 7.0 metres

Including 1.9% Ni, 2.3 % Cu, 10.9 g/t Pt + Pd + Au over 2.1 metres

MCB-24-033: 0.2% Ni, 2.0 % Cu, 11.3 g/t Pt + Pd + Au over 4.5 metres

MCR-24-075: 0.2% Ni, 0.2 % Cu, 17.0 g/t Pt + Pd + Au over 13.0 metres

Dave King, SVP Technical Services stated, “Recent drilling at Crean Hill has focused immediately below the surface exposure of the 109 FW Zone and is providing the definition required to advance our surface bulk sample design. Now that all the required permits are in place, Magna can finalize the bulk sample design and initiate the surface bulk sample in the next couple of months, subject to finalizing a 3^rd party ore processing agreement for the 109 FW ore. Today’s results continue to demonstrate the grade and continuity of mineralization not only at surface but also within the upper levels of the planned underground project, where diamond drilling continues to expand on results released in Q1.”

The Company currently has two diamond drills operating at Crean Hill. One drill is focused on deep exploration targets in the footwall, while the second rig is drilling short holes to better define the near surface mineralization in the 109 FW close to the historically mined Main Zone (Figure 1). To date, there have been 18 short holes completed in this campaign, with 8 holes reported today. This short hole drill program is utilizing a small underground drill rig, capable of completing shallow dip drillholes immediately beneath the mineralization exposed at surface. Additionally, some of these holes are targeting up dip of deeper economic intersections which have not been defined to surface or at shallow depths. Drilling to date has already demonstrated continuity of mineralization on surface in the 109 FW Zone, and Magna is aiming to define additional mineralization which could be included in the surface bulk sample program. Results from the short hole drill program will inform the final design shape for the surface bulk sample that is planned to commence in June or July.

In addition to the surface bulk sample support drilling, Magna has continued to better define the 109 FW Zone to the 150m level (See Figure 2 and news release dated April 3, 2024). This drilling was designed to intersect the 109 FW Zone as perpendicular to the dip of the zone as possible, to better define the thickness of the overall mineralized package and the higher-grade veins within. Historical drilling often intersected at poor angles and inconsistent drill spacing. The upper levels of the 109 FW Zone could form a significant portion of the underground advanced exploration and bulk sample/test mining program anticipated to commence in 2024. Holes MCR-24-073 – MCR-24-075 targeted the southern strike extent of the 109FW Zone.

The high grade, massive sulphide core of the 109 FW Zone has not been well defined below the 150 m level, however historical drilling by Lonmin Canada has intersected massive sulphide veins such as 1.4% Ni, 12.3 % Cu, 24.8 g/t Pt + Pd + Au over 3.4 metres in drillhole LM03920 and 1.0% Ni, 20.1 % Cu, 22.1 g/t Pt + Pd + Au over 2.0 metres in drillhole LM03420 (See Figure 2). Magna plans on completing additional drilling in this area, between 150m-250m from surface, to better define the 109 FW Zone mineralization with the goal of extending the high grade massive sulphide core through these elevations (see Figure 2). This drilling is ongoing, and assays will be released as they are received. Magna has made the decision to include the results from this drilling in the next update to the Mineral Resource Estimate which will be completed in Q3 2024.
