IMPORTANT DISTRICT PLAYER IN THE WAWA GOLD CAMP – EXCELLENT JURISDICTION IN ONTARIO, CANADA

WAWA-HOLDSWORTH LAND PACKAGE • 100% ownership • 1142 acres • 20 km NE of Wawa, Ontario, in Corbiere and Esquega Townships • Close to key infrastructure (rail, road, power, qualified workforce) • Easily accessed by public road and short ATV ride 6

PROPERTY GEOLOGY ALL THE GEOLOGICAL ATTRIBUTES TO HOST A LARGE GOLD SYSTEM – 500 M DEFORMATION CORRIDOR TO TRAP GOLD (IRON FORMATION, MAFIC VOLCANIC ROCKS, GABBROIC INTRUSIONS) 500 m-wide n Deformatio Corridor

HOLDSWORTH GOLD ZONES THREE STYLES OF GOLD MINERALIZATION WITHIN THE 500 M-WIDE DEFORMATION CORRIDOR Auriferous and pyritized Algoma-type Iron Formation And Oxide Sands Zones Soocana Vein System (Lode gold) Pyritized Algoma-type Iron Formation with possible Oxide Sands Zones Golden Goose Shear Zone (Lode gold – BMK discovery)

HOLDSWORTH GOLD ZONES OXIDE SANDS • Primary gold, silver and other precious metals target for near term production • Believed to represent the oxidized cap of a precious metals-rich shear zone • Likely extend 1. 8 km along strike and to a depth of 8 m as indicated by Max. Min Survey (July 6, 2017 News Release) 9

OXIDE SANDS • Trenching uncovered high-grade precious metals zones - assays up to 8. 93 g/t Au. Eq • Sonic drilling program completed to quantify the thickness and vertical distribution of the precious metals – Preliminary assays up to 7. 82 g/t gold over 3. 23 m Overburden Oxide Sands 10

OXIDE SANDS PROCESSING • Loose, unconsolidated material can be extracted as an aggregate • Positive preliminary metallurgical results: ﹣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) 11

WHY INVEST IN MACDONALD MINES? The Company’s near-term exploration program is focused on the Oxide Sands The Wawa-Holdsworth Project has the potential to host a large gold system: • Many gold showings with diversified The Project is ideally positioned for exploitation - roads, rail, regional airport, high voltage power lines, and water are in close proximity Mac. Donald Mines has the technical expertise, experience and tools to successfully develop the property mineralization styles occur in a 500 metre-wide deformation corridor • The geological setting and size of the deformation zone is comparable to Alamos’ Island Gold deposit and Argonaut’s Magino deposit (together > 5 million ounces gold) • There is longer term potential associated with the lode gold mineralization on the property 16
