David Trueman started his geological career as a smelter mechanic in Thompson, Manitoba in 1962, the year INCO blew in its new converters. In the intervening 52 years he has spent time in academia, government, and industry and in the last 37 years specializing in the rare metals field.

Dr. Trueman's interest in rare metals stemmed from the geological examination of structural controls of granite related mineral deposits and in 1977 he joined Tantalum Mining Corp. of Canada (TANCO) which, at that time was producing some 70% of the world's newly won tantalum. He entered the junior mining sector in 1983 when he joined Highwood Resources to work on their Thor lake project and has since worked on rare metal deposits through the Arctic in Canada, Greenland, the USA and USSR, and in Australia, Namibia, Malawi, South Africa, India, the PRC, Brazil, Argentina, Saudi Arabia, Spain, France, Wales, Denmark, and East Germany. His work has focused on the geology, metallurgy, and markets of tantalum, niobium, lithium, rubidium, cesium, beryllium, the rare earth elements, indium, gallium, germanium, tellurium, zirconium and hafnium.

Over the years Dr. Trueman has variously been a member of the Canadian Institute of Mining & Metallurgy, the Geological Association of Canada, the Prospectors & Developers Association, the Manitoba Association of Professional Engineers and Geoscientists and other professional associations. He has served as an adjunct professor, as a lecturer in geophysical and geological short courses, and as a judge in the National Science Fair. He has held a number of directorships on various exploration and producing mining companies, and has authored or co-authored some 71 papers in various professional journals.
