The Sainte-Clotilde quarry (formerly Marcil quarry) near the village of Sainte-Clotilde-De-Châteauguay in Montérégie, Québec, now unfortunately closed to collectors. The quarry operated between (1980-2008) in dolomitic limestone (Beekmantown formation). Superb calcite and quartz specimens were found in large cavities in the 1990s but the quarry was also known for the pyrite, chalcopyrite, anatase, sphalerite, barite and some secondary copper minerals as well.

Here's what looks like what was once a bit of stone ledge, and so stands easily on its broken edge. The top edge is covered in saddled dolomite crystals, whereas the front and back of the specimen are coated in sparkling chalcopyrite, as well as a sprinkling of double terminated quartz crystals. A nice specimen from a closed mine, would display well in a cabinet!
