Fault Zones and Prospects


As we walked back we were just reaching the point of where the faulting should be and there, covered with deep grass, was very faint evidence of an old road going up the mountainside! What was that old road doing there?

Proper Assaying of Placer Samples


The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.
