Toronto, Ontario -May 01,2008; MacDonald Mines Exploration Ltd. (TSXV:BMK) ("MacDonald") and 1289839 ALBERTA LTD ("Alberta Ltd."), an Alberta corporation, and wholly owned subsidiary of Coordinates Capital Corporation ("CCC"), owned and operated by Chris Verbiski, and VP Morton Verbiski, are pleased to announce that they have entered into a Letter of Agreement pursuant to which MacDonald has agreed to acquire a 60% undivided right, title and interest in a new land position in the James Bay Lowlands. The new property, "Wellington West" consists of approximately 528 unpatented claim units totalling approximately 8,250 hectares southwest of, and directly contiguous to the Wellington Property in the "Ring of Fire", Northern Ontario, near Noront's prolific nickel-copper-PGE discovery.

Kirk McKinnon, President and CEO of MacDonald Mines stated, "We are very pleased to have concluded a Letter of Agreement outlining the principle terms of agreement between Alberta Ltd. and MacDonald. The CCC team is a seasoned and very knowledgeable group. They are very well funded and have a bias for action as demonstrated in their very rapid staking program in the James Bay Lowlands. MacDonald is well aware that the ground staked by Alberta Ltd., was of significant interest and had committed to stake this ground in initial staking efforts. This arrangement reflects MacDonald's ongoing efforts to add very successful mining individuals whose skills will enhance our exploration and business initiatives. The CCC team will add considerable insights into nickel exploration, gleaned from their experience with their very successful Voisey's Bay discovery and delineation."

MacDonald will be contracting an airborne geophysical survey to fly the newly acquired claims and will follow up immediately with ground geophysical surveys over the most promising targets.
