Precious Metal Ore Platinum Silver Gold 1800 Ore Knob Copper Mine North Carolina: $275.00
Unusual ore from the 1800s Ore Knob Copper Mine with two cut faces, one whole side and one small window cut on the end. Half a dark color with spotting golden amber and some reddish cinnabar in the other half. Some metal is visible to the eye. Small edge filings from the edge of the darker black portion of the ore is shown setting in nitric and muriatic silver, gold, platinum testing acids. After several minutes the acids ran together with obvious platinum and gold remaining in the acid solution. I have found silver in this spotted type ore before; you can see a small piece of it currently on my store with red spotting. This is a similar but different ore. No magnetic properties. Gold can be seen in some of the spots. There are also small signs of copper. The black portion does have a tarnished quality that is noted when cleaning the raw cut ore. 4-3/8 inches x 4-1/4 inches x 2-3/4 inches, measurements from the longest points of the ores shape.2.6 lbs.
