Neil Campbell’s abilities at geological deduction were responsible for several important mineral discoveries, but it is the Pine Point mine on the south shore of Great Slave Lake in the Northwest Territories with which he was most closely associated.
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.
