The Morey mining district is one of the more interesting localities in Nevada having produced silver sulfosalts including Canfieldite (silver with tin), Fizelyite, Diaphorite etc. Perhaps some of these are present on this old specimen which was as the old Minerals Unlimited tag states "collected and ID by Sidney Williams". There is at least one good crystal of Andorite on this specimens. But there are also many patches of silvery metallics with deep red internal reflections.
