Native Gold (roasted Sylvanite ore)

Cripple Creek District, Teller Co., Colorado

3cm x 2cm x 1.24cm

Ex. Michigan College of Mines No. 1797a


Description/Interesting Notes:

A classic, old time example of "roasted ore" native gold from Colorado!!! The overwhelming majority of the gold recovered at Cripple Creek was recovered as telluride ore (calaverite, sylvanite, etc.) and miners would obtain the gold simply by heating the ore in order to drive off the tellurides and leave behind brilliant blebs of native gold!!! This specimen consists of an old time example of such roasted ore and hosts a rich showing of brilliant yellow native gold!!! This specimen is from the A.E. Seaman Mineral Museum and retains an old Michigan College of Mines label AND its original, antique, glass-lined museum specimen box as well!!! This specimen has an old, handwritten, affixed label on the reverse as well!!! This is OLD material that likely dates to the late 1800's or early 1900's!!! Simply a fantastic, historic example of this classic occurence!!! The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!
