Comments on the geologic information

  • Geologic Description = Diamonds ranging from 0.10 to 0.98 carats were recovered from placer operations on Volcano Creek, a few hundred feet downslope of the 'Crazy-8' possible lamproite structure. These alluvial diamonds have sharp edges and lack abrasions, which may indicate that they did not travel far from their source. Subsequent invesigations revealed G3 and G5 garnets, plus zircons which may indicate a lamproite source (The Mining Record, April 13, 1994).
