Most of the hutchinsonite specimens in collections were recovered from this locality in the 70's and 80's (many had the crystals occurring on orpiment), though over the last 2-3 years I have seen a couple lone examples from more recent workings. This was the largest single lot I have seen-- given how infrequently they were turning up, I was a bit surprised to come across so many-- and I'm posting all of them here.
Hutchinsonite is a sulfide of thallium, lead, and arsenic and is probably one of the few minerals containing thallium that you can actually find a decent specimen of.
