Magna Mining Exploration Update for the Shakespeare Ni-Cu-PGM Project, Ontario, Canada

Sudbury, August 17, 2021 - Magna Mining Inc. (TSXV: NICU) ("Magna" or the "Company") is pleased to provide the following update on exploration activities at the Shakespeare Nickel-Copper-PGM Project.

The exploration drilling program is well advanced, with 5,203 meters drilled to date from a planned program of 9,000 meters. Numerous assay results are pending due to severe delays in assay turnaround times.

"Although receipts of assay results are well behind our expectations, we are encouraged by our visual assessments of the drill core," said Mynyr Hoxha, Vice President of Exploration.

The objective of the current drill program at the Shakespeare Mine is to expand near surface resources and test footwall resource expansion targets around the S-13 Zone. At the Shakespeare Mine, 3,726 metres of drilling in 14 holes (plus one deepened hole) have been completed to date (see Figure 1).

There have been 2,228 samples sent to the assay lab for analysis and to date only 426 received, leaving 1,802 outstanding. This includes ~900 samples which are over 40 days since submission (see Table 1). This issue has been discussed with senior management at the assay provider and attributed to a high turnover in assay lab staff. Steps have been taken to ensure better turn-around-times going forward.

Borehole Electro Magnetic (BHEM) surveys conducted at Shakespeare in June will be repeated over the next two weeks. The objective of the planned BHEM survey is to further refine drill targets in the area of the previously identified large gravity anomaly in the footwall of the Shakespeare deposit (the "Birds Bane Anomaly"). The results of the BHEM survey will be used to design follow up drilling which management aims to complete in Q3.

Regional exploration drilling has also been conducted, including 873 metres in 4 holes at the Springer Pit Copper-Gold targets, located approximately 5-kilometers south-east of the Shakespeare deposit. Samples were submitted for assaying in June and July, and results are pending (see Figure 2).

At the P-4 Nickel-Copper-PGM target, one hole has been drilled and one is on-going, for a total of 604 metres. P-4 is a highly prospective target, located approximately 5-kilometers on trend with the Shakespeare geological system (see Figure 3). The samples from P-4 will be sent to a different assay lab and assay results are anticipated within 4 weeks.

3,800-metres of diamond drilling remains to be completed over the next 6-8 weeks and Magna looks forward to being able to provide both the assay results and BHEM survey results as they become available.
