Arthur White was an active mine financier who, with his partner, raised millions of dollars for more than 50 companies and was instrumental in developing several mines including two of the most prolific producers in Ontario’s Red Lake gold camp - the Campbell mine and its neighbour, which bears his name, the Arthur W. White mine.

Ossian Walli never discovered a mineral deposit, built a mine or operated a mining company, but during his 22 years as principal at the Haileybury School of Mines he influenced hundreds of students who did. Appointed to the position when the school was revived under government direction in 1945, he administered its operations and taught mathematics and mineral chemistry classes.

A lateral thinker long before the term was coined, Harry Warren applied his intellectual curiosity and scientific mind to the field of geochemistry, where he made remarkable contributions to prospecting and mineral exploration. He was a pioneer in a discipline which came into its own, to a large extent, through his efforts.

An internationally renowned earth scientist, J. Tuzo Wilson made significant contributions to the understanding of the dynamic earth, particularly in the fields of geology and geophysics.

Victor Wansbrough served Canada’s metals mining industry with distinction for more than 20 years as the first full-time Managing Director of the Canadian Metal Mining Association (CMMA), the forerunner of the Mining Association of Canada.

Canada’s recent emergence as a centre of excellence for diamond exploration and production owes much to the pioneering efforts of John Williamson, a brilliant geologist from McGill University who discovered, built and operated the highly successful Williamson diamond mine - also known as Mwadui - in Tanganyika (now Tanzania).
