He excitedly told me he was going mining and wanted to know where he should go, how to do it, and so on. After he calmed down, I got excited. “I need to go!” was my response.
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.
These are entry-level machines designed with gold prospecting in mind and with the ability to handle mineralized ground and see nuggets of a grain or so in size, perhaps smaller.
After he excavates the ore down to bedrock, he goes over the bedrock with a metal detector to ensure he didn't leave any gold behind before he backfills the area.
This concept of detecting does not always work as we sometimes get a week or so where the temperatures rise to 116°—sometimes more.
We just completed a trip to another river, and yes, there was definite movement and redistribution of gravels, and other prospectors have seen this as well.
...I got the faintest of rises in the threshold. It was hardly a signal at all, and I thought it was one of the many, deep, hot rocks in the area.
Exposed veins and outcroppings can be a great source for gathering good gold ore for processing. Veins and outcroppings do require a lot of work to free the ore from its earthen grip, but this labor can be very rewarding.
