Report: Carbonate Hill LC007389 The location of this mine is not clearly defined but workings in this area were generally caved. The area was naturally revegetated. There are two partially caved adits located to the east of Highway 200 which are potential hazards; one open for transients and the other located under a 4x4 road and is daylighted under the road. A small seep is located on the workings farther to the east above the collapsed buildings. There is a natural spring and a small pond formed on an open cut or bench to the east of the abandoned cabins. Thirty-two assays from a map by Higgins in the MBMG mineral property files show an average width of the paystreak of ten inches and 0.77 opt Au, 25.5 opt Ag, 0.34% Cu, 7.36% Pb, and 8.4% Zn.
