Robert C. Stanley was the driving force that built Inco into the largest nickel company in the world and one of the world’s most successful mining and metallurgical enterprises. Sudbury, Ontario, with a complex developed around eight mines, and Thompson, Manitoba, with it's large mining and processing complex, are two of a number of communities whose fortunes have gone hand in hand with those of Inco.

Selwyn G. Blaylock devoted a working lifetime to mines and minerals and left a number of monuments to his effectiveness including: A successful Canadian mining and metallurgical enterprise, Consolidated Mining & Smelting Co. of Canada, moving upward in this organization from assayer in 1899 to president and managing director in 1939.

It is largely due to the direction of John Simpson that Placer Development, a predecessor company of Placer Dome Inc., developed a global perspective that characterizes a growing number of Canadian mining companies. Under Simpson’s direction and foresight, Placer became pre-eminent in high-tonnage, open pit mining operations in British Columbia and overseas and in the production of a variety of minerals.
