Here up for grabs is a rare specimen from a little known mine known as the Steel Mine and Saunders Extension in Montgomery county.  The specimen is cut on one side to better show the interior.  I suspect this specimen came from near to the oxidation zone due to the presence of some iron-stained quartz surrounding a non-oxidized core.  The specimen is disseminated throughout with gold ore in very very hard quartz.  The primary products are sphalerite as well as pyrite that has been enriched.  The cores of the pyrite are coated with chalcopyrite and chalcocite.  There also appears to be some small amounts of galena in association.  There are some small specks that I don't think are sphalerite and might be some kind of telluride.  The deposit was similar to that of the Russell mine to the west and the Russell deposit had small particles of tellurides throughout.  The ore, in the early stages of mining, was incredibly rich and it would not be surprising if some of those values came from tellurides.  
The mine first operated in 1832 till 1888.  During this time, multiple shafts, pits and levels were dug with the deepest shaft reaching well beyond 200 foot in depth.  There were 2 types of ore, number 1 and number 2 ores.  Based on historic assays, this would have been number 2 ores based on historic descriptions.  The values did not only come from gold but also from silver with values between 2 to 177 ounces per ton of silver!
Slowly the forest has reclaimed this historic mine and this is a perfect example for your collection of the gold-silver ore that was mined here!  I've never seen a specimen from this mine, ever!
