Prospecting & Detecting
Volume is the Key to Success
June 2017 by Alan J. Chenworth
While recovery rates are important, they must necessarily be secondary to the volume of material processed. Running more material at lower recovery rates is generally preferable to increasing the efficiency of the system.
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.
Gold Mining Boom in the Carolinas
Not too far from the pine-filled mountains, a young boy was exploring along Meadow Creek in Cabarrus County, North Carolina, one fine day in 1799. He discovered a beautiful rock that he took home and put to good use as a doorstop. Shortly thereafter, a jeweler stopped by to visit his folks, and as it turned out, the new doorstop was actually a 17-pound gold nugget. That nugget truly did open a door as it marked the beginning of the first gold rush in America.

My third sample location proved to be my last and most interesting. I needed to look no further.
Late Fall Drywashing
Part of the good thing about this spot is that it is not that far from my home in the famous Virginia City mining district. Not everyone knows this, but the first discoveries around that area were gold placers.
