Find of a Lifetime
May 2013 by David ObesterMy metal detecting hobby began about ten years ago when I bought a used metal detector for about $300. I got it specifically to look for meteorites. It was pretty much worthless, not user friendly, and I did not find anything with it.
The small-scale miner has reasonable opportunity to exploit some of these small, rich placer gold deposits.
The burning question I needed answered was why didn’t the deposit ever get mined of at least one of the valuable minerals? A couple of reasons have come to light.
Our theory was that a dredge would collect far more material in a shorter period of time, leaving us with ounces of gold every day.
The question I had, and likely you have too, is when an old channel is cut, how far does the placer gold in the cut channel move down in a river or creek that continues to erode deeper and deeper?
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.
Oleophilic means "affinity to or attracted to oils," and this includes gold an diamonds.
In October, five of us decided to take an exploration trip into an area called Green Valley. This was perhaps ten miles upstream from where we had gone in September and the difficulty was access. One would think that based on the name it was an easily accessible area not far from a nearby town. This couldn’t be more wrong.
