Angus D. McKinnon
	
Angus McKinnon was a blacksmith by trade, and he later became a businessman.(("Whitehorse Heritage Buildings: A Walking Tour of Yukon's Capitol." Yukon Historical and Museums Association, 1983: 40.)) He staked a hard rock claim in the Whitehorse Copper Belt in 1899. The claim adjoined the Grafter mine west of Whitehorse.((E.D. Kindle, “Copper and iron Resources, Whitehorse Copper Belt. Yukon Territory.” Geological Survey of Canada Paper 63-41. 1964: 29. Includes map.)) The claim was initially called the Last Chance and it was relocated the next year and renamed the Best Chance.((Helene Dobrowolsky and Rob Ingram, "A History of the Whitehorse Copper Belt." DIAND Open File 1993-1 (1):2.)) McKinnon built the McKinnon House in Whitehorse in 1901 and sold the house to the Puckett family in 1908.(("Whitehorse Heritage Buildings: A Walking Tour of Yukon's Capitol." Yukon Historical and Museums Association, 1983: 40.))
	
The Best Chance mine was developed in 1909 by the company operating the Arctic Chief, the Arctic Chief Copper Mines Company of Spokane, Washington.((R. G. McConnell, //The Whitehorse Copper Belt: Yukon Territory.// Canada Department of Mines. Ottawa: 1909: 40.)) The Atlas Mining Company took it over for a short period beginning in 1912 and New Imperial Mines Limited then held the ground to at least 1954. There was no production in that time period.((E.D. Kindle, “Copper and iron Resources, Whitehorse Copper Belt. Yukon Territory.” Geological Survey of Canada Paper 63-41. 1964: 29. Includes map.))
