TORONTO, Nov. 09, 2017 (GLOBE NEWSWIRE) -- MacDonald Mines Exploration Ltd. (TSX-V:BMK) ("MacDonald Mines", the
"Company", or “BMK”) announces that it has completed its Trenching and Sonic Drilling Programs that were designed to assess the
extend of the Oxide Sands trend at its Holdsworth Gold Project.
Quentin Yarie, President and Chief Executive Officer of MacDonald Mines stated, "Our Trenching Program has demonstrated the
extensive length of the Oxide Sands which remain open along strike. The program also enabled us to identify key visual and chemical
attributes of the precious metal-rich units in the soil formation. We expect pending assay results from the remaining
trenches and drill holes to corroborate the visual cues from the material sampled.”
The Company is currently awaiting results on 228 trench samples.

Completion of Sonic Drilling Program
The 2,000 metres sonic drilling program at the Wawa-Holdsworth Project announced on September 20, 2017 has been completed. The
program was undertaken to assess the vertical distribution of the precious metals within the Oxide Sands. Assays are pending for
all 401 holes drilled.
Trenching and Channel Sampling at the Reed-Booth Showing
The Reed-Booth Showing is an exploration target on the Wawa-Holdsworth Project (Figure 2). In addition to the Oxide Sands, the
Company continues to explore the area for lode gold targets. On July 17, 2017 MacDonald announced that a grab sample* containing
13.7 g/t gold was collected adjacent to the Reed-Booth Showing, and grab samples* from float at the main Reed-Booth Showing
(considered representative of the main style of mineralization at the showing) contained 4.77 g/t and 6.0 g/t gold.
*Grab samples are selective and may not represent the true mineralization of the prospect.

The Company has mobilized an excavator and is conducting a trenching and channel sampling program in the area to
sample and assess the potential of the Showing and the associated historical Reed Booth Mine.
Plans for Holdsworth Gold Project
The Company intends to have an inferred resource calculated on the Oxide Sands once all of the assay results have been
received. In addition to the Oxide Sands, MacDonald Mines will also continue investigating the lode gold potential on the
property. The current channel sampling of the Reed Booth Showing will be used to identify diamond drill targets. These
targets will be drilled this winter.
The Company is currently sufficiently financed to complete these activities.
Overview of the Wawa-Holdsworth Project
- Neighbouring Alamos' Island Gold Mine, Argonaut's Magino Gold Project and Goldcorp’s Borden project
- Numerous gold showings with diversified mineralization styles occurring in a 500 metres-wide deformation corridor
- Year-long road access and easy access to rail, road, electrical power, labour force and suppliers
Historic work by previous operators defined three gold targets on the Wawa-Holdsworth Project:
- Greenstone-hosted quartz-carbonate vein deposit (Soocana Vein System and Reed-Booth Showing);
- BIF-hosted gold deposits (gold-bearing pyrite zones in an Algoma-type iron formation);
- Gold-bearing Oxide Sands developed from the weathering of the auriferous pyrite zones.
MacDonald Mines is focusing its near-term exploration program on the Oxide Sands. These appear to extend for
more than 2 km on the property as corroborated by MacDonald’s airborne magnetics results (see June 1, 2017 News Release) and reach
a depth of at least 8 metres.
Positive preliminary metallurgical results (see July 11, 2017);
- The concentration ratio of gold in rougher flotation averaged 6.0:1
- The concentration ratio of silver in rougher flotation averaged 5.2:1
- Reduction of feed volume in rougher flotation by approximately 85-90%
- The Oxide Sands can be processed by a simple crushing/flotation process
- No caustic treatments are necessary
- The processing will require low power requirements
- The waste material is inert (>70 percent silica/quartz)
The soft and relatively unconsolidated Oxide Sands material can be extracted like an aggregate. The Company is
working to better define the Oxide Sands in preparation for their potential extraction.
On-site Quality Assurance/Quality Control (“QA/QC”) Measures
Sand samples were transported in security-sealed bags for analyses to Activation Laboratories Ltd. 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 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 both the Oxide Sands and drill core. As part of its QA/QC program, MacDonald Mines inserts external gold, silver,
platinum and palladium standards (low to high grade) and blanks every 20 samples in addition to random standards, blanks, and
duplicates.
