About MacDonald Mines Exploration Ltd.

MacDonald Mines is a mineral exploration company with an established exploration history in the Canadian Northlands. MacDonald Mines has set upon a strategic direction of exploration with particular focus on nickel, chrome, copper and zinc in the "Ring of Fire" area of the James Bay Lowlands of Northern Ontario.

On its McNugget Property, new volcanogenic massive sulphide (VMS) mineralization of substance has been discovered. Four VMS mineralized greenstone fold limbs, all of which have now yielded VMS mineralization over a potential cumulative strike length of approximately 20 kilometres, have been identified and the McNugget Property has the potential to host a new VMS camp with characteristics similar to those seen at Matagami or Noranda in Quebec.

MacDonald's highly prospective Hulbert-Salo Property contains very conductive and discrete targets within a layered magnetic structure, which is typical of magmatic massive sulphides containing nickel. The Hulbert-Salo appears to have the potential to host a Voisey's Bay-type nickel deposit.

The Company's Big Mac Property exhibits high-priority nickel and copper targets with geological and geophysical signatures similar to the significant chrome discoveries of Freewest and KWG-Spider.
