MacDonald Mines Exploration Ltd. (TSX-V: BMK) ("MacDonald Mines" or the "Company") announces results from the last 7 holes from its 2020 drilling program at Scadding on its 100% owned SPJ Project, 20 kilometres east of Sudbury, ON. Highlights include 4.97gt gold over 3.03 metres, including 15.7gt over 0.95 metres and significant cobalt mineralization over the same interval (see Figure 1, 2 and Table 1). The Company also reports that it has completed 9 of 10 planned diamond drill holes at the Jovan property, 9 kilometres east of Scadding and that assays are pending. Following drilling at Jovan, the drill rig will be mobilized to Alkin-Glade, a target identified by the 2020 IP survey, approximately 1 kilometre south of Scadding, with drilling expected to commence shortly.
Mia Boiridy, President and CEO, comments, " The results from the 2020 program continue to support the Company's geological model that has the Scadding Deposit extending at depth, as well as showing that gold mineralization continues within the 100-metre zone between the historical Scadding underground mine and the South Pit. We will continue the systematic exploration of what we believe to be a large, modified IOCG system at the SPJ Project. For 2021, MacDonald Mines will focus exploration on three areas:
- Continued drilling around, downdip and extensions of Scadding, including Alkin-Glade,
- Exploration and drilling at the Alwin area, 5 kilometres north of Scadding,
- Drilling at Jovan, approximately 9 kilometres east of Scadding.
We will have a full year of drilling and exploration in 2021, expanding the program to 3 separate areas covering a substantially larger footprint spanning several kilometres at the SPJ Project. "

2021 Exploration and Drilling Programs
In addition to the high-grade gold mineralization present at the Scadding Mine, multiple centres of polymetallic (Au, Cu, Co, Ni and Ag) mineralization have been identified on the large 18,340 ha SPJ Project. MacDonald Mines completed five induced polarization ("IP") surveys in 2020 that covered 4.75 sq. kilometres. The surveys identified 49 anomalies, with more than 35 labelled as priority drill targets. Since the beginning of January and continuing for the rest of 2021, the Company is prioritizing drill testing in 3 of the target areas where the geophysical anomalies are associated with known showings of gold and polymetallic mineralization (Figure 3). MacDonald Mine's objective is to test the continuity of known zones of mineralization identified along major structural corridors and continue to show that a modified Iron-Oxide-Copper-Gold ("IOCG") system is present at the SPJ Project.

Scadding
MacDonald Mines' 2021 Exploration Program will continue further drilling at and around the Scadding Deposit. The Company will test the down-dip extension of gold mineralization in the North Pit area and test the underexplored extensions of mineralization west of the historical Scadding underground mine.
Alkin-Glade - Target Area Adjacent to Scadding
The drill is being mobilized to a target area 0.8 kilometres south of the Scadding Deposit, where another large geophysical anomaly was identified through the 2020 IP survey. The anomaly is located north of the Glade showing along strike of a structural corridor that hosts the historical Alkin Gold Mine (ref. MDI41I10NE00023).
Jovan
Nine holes (JV-21-084 to JV-21-092) for a total of over 2,593 metres have been drilled to date at the Jovan Property. Drilling is testing the polymetallic potential of the area. It is targeting geophysical anomalies identified by the latest IP survey in the Ess Creek Structural Corridor where MacDonald Mines' 2018 channel sampling at the Brady Showing returned up to 3.81 g/t gold, 3.44% cobalt, and 0.59% copper over 1.5 metres, and grab samples assayed between traces and up to 24.2 g/t gold. The reader is cautioned that grab samples are selective by nature and do not represent the true metal content of the mineralized zone. A map of completed and planned holes at Jovan is provided in Figure 4. Assay results are pending and will be released when received.

Alwyn
The historical Alwyn Mine will also be targeted in 2021. McDonald Mines plans to complete an IP survey over the mine to direct drilling. Historical drilling at Alwyn reported up to 16.59 g/t gold over 1.52 metres and 4.46 g/t gold over 3.81 metres . Copper values were not reported during the 1983 drilling program (Haultain Resources, 1983, AFRI 41I10NE0154). The reader is cautioned that the data is historical in nature, and the qualified person has not independently validated the accuracy of the historical results. The true width of the intersected zone of mineralization is unknown.
Additional Claims Acquired
The Company has signed a definitive agreement to acquire a 100% interest in 4 claims (the "Claims") located on the Jovan property (Figure 4). This acquisition adds 36 hectares to the Company's land position. The acquired claims cover an extension of the geophysical anomaly that MacDonald is currently targeting in its ongoing drilling program at Jovan.
Acquisition Terms
To acquire an 100% interest in the Claims, on closing, MacDonald Mines agrees to:
| (i) | pay to the Vendor C$75,000 in cash; and |
| (ii) | issue to the Vendor the equivalent of C$75,000 Class A common shares in the capital of the Company based on the previous 5-day VWAP (subject to TSX-V approval); |
The complete terms of the transaction will be available on SEDAR under the Company's profile.

Qualified Person
Jean-François Montreuil, P.Geo., Chief Geologist of MacDonald Mines, is the qualified person as defined by National Instrument 43-101 Standards of Disclosure for Mineral Projects , responsible for preparing, supervising, and approving this news release's scientific and technical content.
On-site Quality Assurance/Quality Control ("QA/QC") Measures
Drill core samples were transported in security-sealed bags for analyses to Actlabs in Ancaster, Ontario. Individual samples are labeled, placed in plastic sample bags and sealed. Groups of samples are then placed into durable rice bags and then shipped. The samples transported to Actlabs were dropped in rice bags with security seals by Manitoulin Transport. The remaining coarse reject portions of the samples remain in storage in case further work or verification is needed.
MacDonald Mines has implemented a quality-control program to comply with best practices in the sampling and analysis of drill core. As part of its QA/QC program, the Company inserts external gold standards (low to high grade) and blanks every 20 samples in addition to random standards, blanks, and duplicates. All samples over 10 g/t gold or the samples with abundant visible gold are analysed by 1 kilogram metallic screen. Check assays are routinely performed for samples with visible gold to ascertain the gold content of the mineralization zone.
COVID-19 Precautions
MacDonald Mines has developed and implemented precautions and procedures that are compliant with Ontario's health guidelines. Strict protocols are in place to ensure the safety of all staff, thereby reducing the potential for community contact and spreading of the virus.
