The specimen is mostly a solid leaf of Silver with a coating of Acanthite. This has good provenance with an old inked label stuck on the specimen and dated 1980. With it is a nice large label from the "Department of Mines Geological Survey" of Canada with a number matching the specimen (7720). Documentation of a specimen's history does not get better than this.

Superp platy, red, translucent Allactite crystals from 1-3mm. Excellent piece, most likely from the 1981 find. I previously thought these were Sarkinite, as labeled from the Shultz collection. An expert in Franklin as to me otherwise.
