McIntyre worked for 30 years in the mineral business, the last part of these in the hard-rock mineral exploration as an officer or director of several public mineral exploration companies. He was a policy analyst for several years for the governments of Ontario and of Canada. He was the president and founder of Northwest Exploration Company Limited and a director of its parent company, Northwest Explorations Inc. When Northwest Explorations Inc. was taken over in 1998 by CGX Resources Inc. to form the oil and gas exploration company CGX Energy Inc., McIntyre ceased being a director. McIntyre was a strategic advisor for CGX in 2000 through 2003. McIntyre says that during his career his skills in statistical analysis enabled him to analyse mineral prospecting data and out-bet his rivals.
