Valleriite, Whitehorse Copper Mine, Whitehorse, Yukon Territory

I had the opportunity, recently to Visit the Whitehorse area. While there, I was fortunate to collect some excellent valleriite at the old, now closed, Whitehorse Copper Mine. Valleriite is a fairly rare Copper-iron-magnesium-aluminum-hydroxyl-sulphide. I'm not sure if that is the absolutely correct way to state the type of mineral it is but it does accurately describe the chemical make-up. Valleriite occurs at Whitehorse copper in soft brown, metallic masses in serpentine and sometimes, massive bornite. These are impressive specimens. These al came from the Little Chief deposit. I did not collect them all.
