/NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES/

MacDonald Mines Exploration Ltd. (TSXV: BMK, OTC: MCDMF) ("MacDonald Mines" or the "Company") is pleased to announce that it intends to complete a non-brokered private placement financing of up to C$4.0 million of units (the "Unit Offering") and "flow-through" units (the "FT Offering", and together with the Unit Offering, the "Offering").

The Offering will consist of (i) a minimum of 25,000,000 units (the "Units") at a price of C$0.04 per Unit for gross proceeds of a minimum of C$1.0 million (the "Minimum Offering") and a maximum of up to 50,000,000 Units for gross proceeds of up to $2.0 million (the "Maximum Offering"), and (ii) up to 44,444,445 flow-through units (the "FT Units") at a price of C$0.045 per FT Unit for gross proceeds of up to C$2.0 million. Each Unit will consist of one common share (a "Common Share") in the capital of the Company and one-half (1/2) of one Common Share purchase warrant (each whole Common Share purchase warrant, a "Warrant") of the Company. Each Warrant shall be exercisable to acquire one Common Share at a price of C$0.07 per share for a period of 24 months from the closing date of the Offering. Each FT Unit will consist of one Common Share to be issued on a "flow-through" basis, and one-half of one Warrant.

The Company is relying on the temporary relief measures announced by the TSX Venture Exchange (" TSXVE ") on April 8, 2020 and June 17, 2021 (the "Temporary Relief") in offering the Units and the FT Units at a price that is less than $0.05. Pursuant to the Temporary Relief, the Issuer will not issue more than 100% of its issued and outstanding Common Shares pursuant to the Offering. All securities issued under the Temporary Relief will be subject to a TSXVE hold period in addition to the restricted period under applicable securities laws and will be legended accordingly. The proceeds of the Offering will not primarily be used to pay management fees or for investor relations activities. Please see the table below for use of proceeds from the sale of Units.

MacDonald Mines is also pleased to announce that it has entered into a strategic relationship with GoldSpot Discoveries Corp. (TSXV: SPOT, OTCQX: SPOFF) ("GoldSpot") to assist in the advancement of the Company's SPJ Project located approximately 40 km east of Sudbury, Ontario. GoldSpot will utilize its artificial intelligence and machine learning technologies to optimize exploration targets, allowing the Company to better focus drilling efforts and unlock value across MacDonald Mines' significant landholdings.

Commenting on the relationship, Interim Chief Executive Officer of MacDonald Mines, Stuart Adair, stated: "We are delighted to welcome GoldSpot as a strategic service provider of MacDonald Mines. The SPJ Project will benefit tremendously from the assistance of GoldSpot's technologies and data-driven approach to exploration. Our team looks forward to working with the GoldSpot team to evaluate and unlock the potential of the SPJ Project."

Commenting on the transaction with MacDonald Mines, Denis Laviolette, Executive Chairman and President of GoldSpot, stated: "GoldSpot is excited to provide our proprietary technology to MacDonald Mines. The size of the SPJ Project's land package is substantial and we believe the large number of potential targets on the property are ripe for further analysis and refining under our team's technological and geological guidance."

The proceeds from the Unit Offering will be used by MacDonald Mines as set out in the Use of Proceeds table below, assuming the raising of either (i) the Minimum Proceeds and (ii) the Maximum Proceeds. The Offering of Units will only close if the Minimum Proceeds are raised. If more than the Minimum Proceeds from the sale of Units are raised, all additional funds up to the Maximum Proceeds will be used as set out in the Use of Proceeds table below. There is no minimum for the sale of the FT Units in the FT Offering, which proceeds will solely be used to incur Canadian Exploration Expenses.

The gross proceeds from the sale of FT Units in the FT Offering will be used by the Company to incur eligible "Canadian exploration expenses" that will qualify as "flow-through mining expenditures" as such terms are defined in the Income Tax Act (Canada) (the "Qualifying Expenditures") related to the Company's projects in Canada. All Qualifying Expenditures will be renounced in favour of the subscribers of the FT Units effective December 31, 2021.
