Magna Mining Phase I 9,000m Drill Program Update at the Shakespeare Ni-Cu-PGM Project, Ontario, Canada

Sudbury, Ontario--(Newsfile Corp. - May 26, 2021) - Magna Mining Inc. (TSXV: NICU) ("Magna" or the "Company") is pleased to announce that it has commenced the planned 9,000 metre, Phase I drilling program at its Shakespeare Project, located near Sudbury, Ontario.

Magna has allocated 6,000m of drilling to near-mine exploration targets at the past-producing Shakespeare Mine, and 3,000m to high priority regional exploration targets. At Shakespeare, drilling is designed to expand on the current National Instrument 43-101 Mineral Resource Estimate, beneath and within the footwall of the known mineralization.

Initial drilling will focus on the Gap Zone, between the existing Shakespeare East and West zones, as well as drill targets within the footwall of the known deposit, where recent surface geophysical surveys have defined anomalies that may represent sulphide mineralization. Additional borehole geophysical surveys, scheduled for early June, will be completed on the initial footwall drillholes to better define the identified geophysical anomalies, and guide additional drilling. Figure 1 illustrates the general location of the target areas. Five drillholes have been completed to date, and Magna anticipates initial assay results will be in June.

Resource expansion drilling is focused on the Gap and S-13 areas and drilling in the footwall of the East zone will test surface geophysical anomalies and provide platforms for down-hole geophysical surveying.

The second component of the Phase I drilling program includes 3,000m of drilling designed to test high priority exploration targets within the 180 km² land package that surrounds the Shakespeare Mine (see Figure 2). Regionally, Magna has identified twelve, near surface, electro-magnetic (EM) geophysical anomalies, which could potentially represent conductive sulphide mineralization, similar to the known Shakespeare Deposit. The EM anomalies are defined within 200m of surface and have not been drilled historically. The 2021 regional exploration program is designed to test three high priority targets associated with sulphides identified on surface and anomalous surface sampling. These targets are:

• P-4 target: Located 5km east of the Shakespeare deposit along the same magnetic trend and associated with gabbroic rocks, similar to those that host the Shakespeare Deposit. Historically Ursa Major mapped and drilled mineralization 500m east of the high conductance EM anomalies defined by Magna (Table 1).
• Hanover target: Located 5km northeast of the Shakespeare Deposit, the Hanover target has had limited surface mapping. Surface mineralization at Hanover consists of disseminated and blebby sulphide. Although these sulphides account for <2% of the rock there are anomalous copper and platinum group element (PGE) values as outlined in Table 1.
• Springer targets: The third target to be tested during the initial program is the Springer and Springer Extension targets, which consist of a highly conductive zone associated with chalcopyrite mineralization. Copper grades reaching 7%, and associated anomalous gold have been identified in surface sampling (Table 1).
