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.
How many more clays seams lie adjacent to known shear zones and quartz veins in the pocket areas of southwestern Oregon?
