BMK MacDonald Mines Exploration Ltd

MacDonald Mines Exploration Ltd. (TSX-V: BMK, OTC: MCDMF) (“MacDonald Mines” or the “Company”) is pleased to announce the Company has entered into a binding Sales and Purchase Agreement (“Agreement”) with Environmental Tailings Corporation (“ETC”), a private Ontario company incorporated for the purpose of undertaking reclamation of mine-site tailings. MacDonald Mines has transferred to ETC a lease area of 63.9 hectares (“Lease”), which encompasses the historical Scadding Tailings (“Tailings”).

Highlights of the Agreement:

• MacDonald Mines has transferred the Lease which encompasses the Tailings to ETC for $1.00 but will retain the mineral and mining rights of the Lease unhindered
• ETC will be responsible for all costs associated with the processing and rehabilitation of the Tailings as set out in the closure plan
• ETC has granted MacDonald Mines a 4% net smelter return from the sale of any metal extracted from the Tailings
• ETC will resell the Lease to MacDonald Mines for $1.00 once the Tailings have been processed and the site has been restored as set out in the closure plan
• ETC has covered all of Macdonald Mines costs associated in preparing this Agreement

Mr. Greg Romain, President & CEO of MacDonald Mines, stated: “MacDonald Mines is pleased to have entered into this agreement with ETC as they will complete the required closure of the Scadding Tailings while allowing the Company to participate in any success they have on the tailings recovery by way of an NSR.” Mr. Romain added; “This transaction helps the Company preserve cash while ensuring our focus and efforts remain on exploring our 100% owned SPJ project. Furthermore, it confirms our commitment as a company to clean up any historical workings which is supported by the government of Ontario.”

Historical Scadding Tailings

The historical Scadding Tailings formed part of the Scadding leases that MacDonald Mines acquired on April 30, 2019. The milling on the property was done between 1987 and 1990 where a total of 140,000 tonnes were processed at a grade of 7.22 g/t (National Instrument 43-101 Technical Report for the SPJ Project, October 18, 2019).

The 63.9 hectares Lease transfer represents less than 0.5% of the SPJ project land package.
