A small specimen obtained in Wallace, ID by my husband at a yard sale. It's on platy galena with lots of small reticulated cerussite crystals. I was researching native silver and the images I came up with helped to ID this specimen. After washing it (it's dirty again, lol) I found a little silver node tucked in the cerussite on one edge. It's ropy and bright!
Specimen is less than an inch square and L shaped like a corner. Crystals are less than 10mm across. Magnification is x30.

Mindat says, "Bunker Hill is neoprot. Polymetallic deposits in neoprot. quartzite of the St. Regis and Revett fm's... Shallow ore bodies mined in the 1880's - 1900's were largely oxidized with cerrusite as primary ore mineral." Which this specimen is.
The mine has produced prolific amounts of zinc, lead and silver primarily and is now operated by a Canadian company looking to exploit smaller overlooked veins that were bypassed in the past due to them being worth more to pursue than prospective yield would garner post-smelting.

Great photos and a nice addition to all our jasper and agate stuff..... Maybe I will get around to identifying the dozen or so mineral / ore specimens I have from Idaho. Not as cool as yours though. awesome

Thanks for the kind words. It would be great to see what you've got hanging around. I don't think I've yet to see an Idaho rock that wasn't ta least interesting geologically.
