One Potato, Two Potato...

We all love to see that first glimmer of gold when it peeks out from under the black sand in our pan, or feel the weight of a nugget in our scoop when we dig a good target. But sometimes things don’t go quite so smoothly.
When working fine gold placers with a drywasher, there are some natural variables that can be beneficial as well as others that can be a hindrance to achieving good recovery.
We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.

We were met with a plethora of mechanical problems with the dry washer and even a few with the excavator that were at times frustrating, but we were in this for the long haul, so we needed to solve these problems and move forward.
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.
I love to see old-timer workings while I am out detecting for gold. For one thing, it assures me that gold came from there. Second, it tells me gold should almost certainly still be there.
