American Bonanza's Copperstone Mine Ships First Gold

摘要

American Bonanza Gold Corp. reported that the 100% owned Copper-stone gold mine in Arizona has placed onto transport its first shipment of gold bearing concentrates. The first concentrate shipment consisted of 31.2 tons of concentrate grading an average of 22.8 ounces per ton of gold, containing an estimated 712 ounces of gold in concentrate. Gold content grades in the concentrates are over double the most optimistic expectations, and Bonanza continues to pursue further improvements to the gold grade in concentrate.
