For the past year, Mike was Country Manager, Exploration for First Quantum Minerals Ltd. in Mauritania where he was responsible for exploration for the Guelb Moghrein Copper-Gold deposit. Prior to this, he was Director of Exploration for the Saudi Arabian Mining Company where, under his direction, the company made several large discoveries totaling in excess of several million ounces of contained gold. Prior to this, over a period of almost 10 years, Mike was Senior Geologist, District Manager - Mexico and District Manager - Western Canada for Cyprus Exploration Co. evaluating acquisition opportunities and carrying out exploration projects worldwide. While at Cyprus, Mike headed the geological section of the Cyprus team that evaluated and acquired the Kubaka Gold Deposit in the Russian Far East and then guided the geologic section through feasibility leading Cyprus to becoming one of the first western mining companies to develop a new mine in the former CIS. Mike's career began in 1969 as an underground laborer, mine surveyor and Assistant Geologist. From 1976 to 1983 he was with the San Luis Mining Co./Luismin - initially as a Mine Geologist, District Geologist and later as Director of Exploration managing exploration for precious and base metal deposits throughout Mexico.

Mike is directly responsible for the discovery of two deposits (owned by Luismin, a subsidiary of Wheaton River Minerals Ltd): (1) The Santa Rita Silver-Gold Deposit in Durango Mexico, near the Tayoltita silver-gold mine, which has been a principal source of silver and gold for the Tayoltita operation; and (2) The San Antonio Gold-Silver Mine in Sinaloa, Mexico, which was a high-grade silver-gold deposit located in a remote portion of the Mexican Barranca region. Luismin owed its strong financial position in large part to profits gained from these operations.
