TORONTO, Nov. 19, 2020 (GLOBE NEWSWIRE) -- MacDonald Mines Exploration Ltd.
(TSX-V: BMK) (“MacDonald Mines”, “MacDonald” or the “Company”)
reports further assay results from its ongoing 2020 drilling program at the
SPJ Property, located 40 km east of Sudbury, Ontario. Hole SM-20-065
intersected, near-surface, 7.18 g/t gold over 13.23 metres, including 41.44
g/t gold over 1.09 metres and 22.60 g/t gold over 1.00 metre, further
expanding the high-grade gold mineralization of the Scadding Deposit (Figure
1). Drilling continues with approximately 7,548 metres of the 14,000 metres
program completed and 74 holes drilled to date (Figure 2). Further assay
results are forthcoming and will be released as they are received.

Holes SD-20-058 and SD-20-059 of the program also revealed broad zones of gold
mineralization west of the Scadding Deposit, in an area that has seen little
exploration in the past. Hole 59 intersected a broad zone of gold
mineralization in the Bristol/Monaco corridor that further supports the
extension of gold mineralization, beyond the current footprint of the Scadding
Mine, between the mine and the South Pit.

MacDonald’s focus through December 2020 is to continue drilling the large
exploration gaps that exist between the Scadding underground mine and both the
North Pit and South Pit areas.

Quentin Yarie, MacDonald’s President and CEO stated, “We continue to drill
new zones of high-grade gold mineralization in the Bristol/Monaco deformation
zone, confirming how we can expand the historic Scadding Deposit. Results are
suggesting that a parallel corridor of gold mineralization exists to the west
within the Bristol Breccia which extends over a strike of 200 metres and
remains open in all directions. We are starting to see indications of chlorite
alteration that could be indicative of further undiscovered zones of
higher-grade gold mineralization in the Bristol Breccia structure. While
drilling continues, we are utilizing the results of our recent IP surveys to
further guide the deposit expansion drill program.”

Detailed Description

Hole SM-20-057 was testing the continuity of the Bristol/Monaco Structure
beyond the underground workings of the Scadding Mine. Hole 57 successfully
intersected the deeper extension of the structure with a zone, approximately
16 metres-wide, of pervasive magnetite alteration with an elevated background
in gold. Hole 57 also intersected a narrow zone of chlorite alteration, with
specks of visible gold, in a satellite structure located in the Scadding Mine.

Hole SM-20-058 was testing the northern extension of the mineralization zones
at the Scadding Mine. Hole 58 successfully intersected a zone of chlorite
alteration in which visible gold was observed, but this did not return
significant gold assays. Hole 58 also intersected a large breccia zone, west
of the Scadding Mine, the Bristol Breccia where gold mineralization is
associated with pervasive dissemination of pyrite in a silica-rich breccia

Hole SM-20-059 was testing the Bristol/Monaco Structure between the Scadding
Mine and the South pit and successfully intersected a zone of
chlorite-magnetite alteration in the structure, suggesting the potential
continuity of mineralization between the South Pit and the Scadding Mine.
Additionally, hole 59 discovered a new zone of gold mineralization west of the
Bristol/Monaco Structure likely associated with the Bristol Breccia. Gold
mineralization in that new zone occurs as pervasive disseminations of pyrite
associated with silica-carbonate alteration. Rims of chlorite around some of
the carbonates suggest that zones of chlorite alteration, typically associated
with higher-grade gold mineralization, could be present in that new structural
corridor west of the Scadding Deposit.

Hole SM-20-064 was testing the deeper extension of gold mineralization in the
South Pit area. Hole 64 successfully intersected the extension of the
structure characterized by pervasive magnetite alteration, but that extension
did not contain significant gold mineralization.

Hole SM-20-065 was testing a zone of chlorite alteration exposed at surface
between the Scadding Mine and the South Pit. Hole 65 demonstrated that
significant gold mineralization and near-surface zones of chlorite alteration
are left to be discovered at the Scadding Mine and between the mine’s
current footprint and the South Pit. Additionally, hole 65 intersected a zone
of low-grade gold mineralization in the Bristol Breccia west of the
Bristol-Monaco structural trends of the Scadding Deposit.

Hole SM-20-066 was testing the northern extension of the structures
controlling chlorite alteration and gold mineralization in the Scadding Mine.
The hole was stopped before reaching target as it intersected the underground
workings of the Scadding Mine.

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 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, MacDonald 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.

SPJ Property Highlights
* 100% ownership
* 18,340 hectares in excellent mining jurisdiction and close to infrastructure
* Hosts the high-grade past producing Scadding Gold Mine
* Evidence of polymetallic mineralization at the Scadding Deposit indicative
of IOCG potential
* Significant gold, cobalt, copper, silver, nickel and rare earth showings
outside of the Scadding Deposit footprint
Historically, the Scadding Mine produced 914 kilograms of gold from 127,000
tonnes of mineralized material grading 7.2 g/t (OFR 5771). MacDonald’s
reinterpretation of the geological model at the Scadding Deposit and larger
SPJ property indicates that it could host a gold-rich Iron-Oxide-Copper-Gold
deposit and that significant gold bearing structures have been missed by
previous operators’ exploration campaigns (2009-2011).
