Second Bench, Kidd Creek Mine Open Pit
Timmins
Ontario,
Canada
This silver specimen is from the collection of a retired mining engineer that worked at the mine 40 years or so, ago. I worked there 35 years ago when I was a student! At that time, when the open pit mine was operating, significant native silver was recovered in the zinc(sphalerite) orebody, in quartz. Kidd Creek mine was producing 10-14 million troy ounces of silver a year at that time as a BYPRODUCT of base metal mining. This is an excellent example of that material. It shows a leaf of silver in white quartz, with most of the matrix solid, dark-brown sphalerite. Excellent and unusual!

La Mina San Martin

This mass of solid purple-blue bornite has an opening at the end that is richly endowed with very bright wire silver crystals. There are bornite crystals present but they are very rough. There are crystals of black copper sulphide (chalcocite? digenite?) present in fairly sharp crystals. Nice silver specimen from an unusual locality.
