TORONTO, Sept. 09, 2021 (GLOBE NEWSWIRE) -- MacDonald Mines Exploration Ltd.
(TSX-V: BMK, OTC: MCDMF) (“MacDonald Mines” or the “Company”)
announces that Mia Boiridy has left the organization, effective immediately.

Stuart Adair, CPA, CA, MA, BA, a member of the Board of Directors of MacDonald
Mines and Chair of its Audit Committee, has been designated as the Company’s
interim Chief Executive Officer effective September 8, 2021. Mr. Adair has
extensive financial and operating experience as a “C” suite executive and
will provide support, direction, and guidance to MacDonald Mines’ Management
during this transition.

MacDonald Mines priorities are to continue with our business plan, deliver on
our exploration models, and maintain a stable and effective organization. The
Board of Directors has commenced a search for a new CEO. We thank Mia for her
contributions and wish her success in her future endeavours.

MacDonald Mines also reports on results from its Summer 2021 mechanized
stripping, channel sampling and regional prospecting program at its 100% owned
SPJ Project, 30 km east of Sudbury, Ontario (Figure 1).

In the Glade area, channel sampling extended gold mineralization in the
Alkin-Glade trend over 225 metres along strike. Exploration work in the Glade
area also led to the discovery of a broad zone of anomalous gold in the
Espanola limestone 150 m below the mineralized Alkin-Glade corridor in hole
AG-21-097. Channel sampling at the Jerome showing indicates that the Nipissing
intrusion contains palladium-rich mineralization.

Fall 2021 exploration plans

During the Fall of 2021, the Company plans to complete the channel sampling
and mapping program in the Glade and Alkin areas of the Alkin-Glade trend in
preparation for diamond drilling in the Alkin-Glade corridor. The first phase
of the drilling program will consist of a series of drill holes to test the
continuity of gold mineralization between the Glade East and Glade West
showings, separated by 225 m.

In parallel, the Company plans to prospect, sample and map the McLeod showing
where historic diamond drilling intersected significant gold mineralization.
The Company also plans to prospect and map gold-copper mineralization at the
historic Alwyn Mine and explore for additional palladium-rich mineralization
in the Nipissing sill hosting the Jerome showing,

Alkin-Glade

The Alkin-Glade trend is located at the contact between a Nipissing intrusion
and sedimentary rocks. The structure hosts two significant zones of
mineralization - the historic Alkin Mine and the Glade showings. In the Glade
area, Ontario Geological Survey maps and historical exploration identified a
broad zone of disruption, alteration, deformation and mineralization that
extend over a strike length of 300 m. High-grade gold in quartz veins was
reported historically. Old exploration trenches, now overgrown with vegetation
are the only evidence of the 1930’s and 1940’s exploration work done at
Glade with gold mineralization still exposed at the Glade East and Glade West
showings.

The historical Alkin gold mine is located 2.2 km W-NW of the Glade showings.
At the Alkin mine, gold mineralization occurs as a network of quartz veins
hosted in the felsic phase of the Nipissing Diabase intrusion that also hosts
the Glade showings. Reconnaissance work by the Ontario Geological Survey
reported gold assays up to 38.8 g/t gold in grab samples taken from the veins
exposed at the Alkin Mine (OFR 5771). The reader is cautioned that grab
samples are selective by nature and do not represent the actual grade of the
targeted mineralization. In addition, the reader is cautioned that a qualified
person has not done sufficient work to validate the accuracy of the historical
results. The Company is not treating the historical estimates as current
mineral resources.

Diamond drilling under the Glade West Showing in holes AG-21-096 and AG-21-097
revealed a large alteration and mineralization system where shear-hosted
quartz veins are surrounded by networks of gold mineralized, multidirectional
and variably spaced quartz tension veins concentrated in the Nipissing
intrusion at its northern contact with the Bruce conglomerate. Diamond
drilling also identified that mineralization extends in the Espanola limestone
along the southern contact of the Nipissing diabase hosting the networks of
gold-bearing shear zones and quartz veins. Visible gold was observed in many
of the quartz veins in both holes AG-21-096 and AG-21-097, and in the channel
samples taken at Glade East. Surface work at the Glade East showing confirmed
comparable mineralization 225 m east of the Glade West discovery. Visible gold
is associated with iron-rich chlorite alteration emplaced and crosscutting the
quartz veins. This association between gold and iron-rich chlorite observed at
the Glade West is similar to the iron-chlorite and gold at the Scadding
Deposit. The observed relationship in mineralization could represent a
considerable extension of the mineralized system of over 800m.

Jerome Showing
The Jerome showing is located on the Rathbun block of the SPJ property. PGE
mineralization is hosted in an intrusion pertaining to the Nipissing sills
according to the Ontario Geological Survey maps of the area. PGE
mineralization is associated with disseminations of pyrrhotite, chalcopyrite
and magnetite in the Nipissing sills. The base metal results for the channel
samples taken by MacDonald Mines remain pending.

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 analysis to
Actlabs in Ancaster, Ontario. Individual samples are labelled, 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 if 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 analyzed using a 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.

About MacDonald Mines Exploration Ltd.
MacDonald Mines Exploration Ltd. is a mineral exploration company
headquartered in Toronto, Ontario that trades on the TSX Venture Exchange
under the symbol “BMK”.  

The Company is focused on developing its 100%-owned SPJ Project in Northern
Ontario. Following up on its successful 2019/20 exploration and drilling
campaigns, MacDonald Mines is focused on what it theorizes to be a large gold
