John R. Colbourne
	
John Colbourne was the mayor of Dawson in 1954. He may be the same Colbourne who, in 1950, was partnered with Ernest Schink to operate a mine with two employees on Hester and Hunker creeks near Dawson.((R.L. Debicki, ed. “Yukon Mineral Industry, 1941 to 1959.” DIAND, Whitehorse, 1982: 71.))
