This is the mine where my father worked from 1935 to 1962. It no longer exists in this configuration. It all disappeared when the mine became an open pit operation many years later. Even the highway from Val d'Or to Montreal was moved. Gold motivates decisions, not town planning! That head frame was designed by my father as was the hoist. Memories!
I have posted this because the most popular post on my blog has been one on Sigma. Perhaps those people will find a photo of the actual buildings on surface in the early days of interest!
