St Robert de Bellamin

Last Summer I made a couple of visits to the St Robert mine. I was fortunate to meet a mining engineer, who was taking some GPS coordinated to locate tunnels. He led me down a road that went to an adit. The adit was sealed but I got some photos through the steel door anyways. The dump material had been bulldozed recently to be used for fill in a nearby mill site. The material that was moved turned out to have some quartz crystals with cosalite inclusions. This was different. I also picked up some scheelite which was characteristically fluorescent blue.
Also I found some nicely formed pyrite crystals, and a sulfide that could have been galena mixed with pyrite. But it may also have been cosalite. It was not analyzed but it had the same color. I was sure I found the cosalite when I saw the needle xls in between quartz openings.
I would like to go back to this place with a portable black light in the dark. It is hard to distinguish the scheelite in daylight, but I succeeded in find some nice pieces anyways.
