Flambeau Mine chalcocite

I have a beautiful specimen of chalcocite from Flambeau that was collected many years ago. It weighs about 5 pounds. It is 8% copper, 5% nickel and 1.5 % gold.

It has been stored in a damp basement for 7 years, a tool shed for 7 more and in a house prior. There is absolutely no sign of decomposition or oxygenation or otherwise.

I have other specimens, collected in the Hardin Co. Illinois Fluorite district that have been stored along side of the Flambeau that are rapidly turning to dust.

I believe it could be microbes, but humidity and oxygen seem to also be factors.

George, you might want to consider finding a new analyst. A Flambeau chalcocite with 5% nickel, 1.5% gold, and only 8% copper??? One wonders what the analyst was smoking

My thoughts exactly, Alfredo....

That's quite a specimen with over an ounce of Au. When Au hits $2 grand/oz, you might consider smelting it

In addition to the deterioration factors that were mentioned already: chalcocite is known to be light-sensitive - its oxidation is accelerated by exposure to light. Therefore during storage some protection from light is generally recommended.

yea um i am 12 so i have no idea what those words mean...can you explain a little bit more????
