  • Aton Announces The Discovery Of High Grade Gold-bearing Veins

    Oct 16, 2017 · The vein is hosted mainly by coarse andesitic tuff breccias. Free gold is locally abundant in both the quartz vein and in the phyllic altered wallrock. The gold in the wallrock is always very fine grained, mossy and deep yellow while the gold in the vein quartz can be yellow to white (electrum) and grains can reach 1-2mm.
