10/29/2020 (T Pettigrew) - The “Chalco” site is underlain by mafic metavolcanic rocks. Iron-carbonate alteration and iron-carbonate veins are present, but quartz veins are more common here than in the other sites. Chalcopyrite is present as a major constituent in a series of shallowly dipping quartz veins. A selected grab sample from one of these veins returned 0.23 ounce of gold per ton and 6.8 ounces of silver per ton. A repeat analysis of the additional material from the same sample returned 0.34 ounce gold per ton and 7.3 ounces of silver per ton (Lichtblau et al., 2012). Samples taken on the surface of the vein system returned up to 4.13 ppm Au, 283 ppm Ag, and 11.5% Cu (Assessment report 20000007832).
