Ancient River Channels of Trinity County
June 2013 by Ray MillsTrinity County is located in the far northwest corner of California and stirs up many different memories for those who have been there.
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
The biggest nugget I have found detecting here was three grams and the following weekend someone found a 9-gram nugget while detecting. Some have even found quarter-ounce nuggets, with one being a chevron nugget.
The amount of gold in the traces from the low-grade scattered veinlets may be much more than the traces from the small but rich pocket, at least until the pocket hunter closes in on the rich pocket. Further confusion arises if the prospector stumbles across a placer deposit on one of the higher peaks.
Some of the items that I’m going to go over are outcroppings, ditches, exploratory trenches and contacts/surface materials. I am going to speak about each of the above items in as much detail as I can, and then towards the end of this article I will tie them together.
The signal I was hearing was coming from a vertical bedrock crack on the bank of the creek. I removed my backpack, took out my crevicing tools and started to clean out the crack when I saw a glint of gold.
That is the course and intention for this article—to wander through some of the lessons I have learned in my thirty-two years of metal detecting and prospecting.
Many years ago I was in the American Canyon. I remembered a few details about a placer deposit there, so we decided to make a trip down and re-check some of these old workings.
