Im selling this beautiful 150 lbs rare specimen Gold,Silver and Copper and Garnet found miles in the underground mines of the Santa Catalina. Ive got another piece about 80 lbs that I wanna refine. Is anyone familiar with this rock, and the method I can use to separate those metals, or should I just cut and polish? If anyone is interested in this rock shoot me a pm
thanks for your opinion
