Enrichment of Mineral Deposits by Weathering—Part I
March 2016 by Chris RalphThe exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.
When you think about the extremes to which a miner will go to get a little gold, it occurred to me beach gold could be "easy pickings."
Perhaps the most notable thing about skim placers is that they form on the top surface of gravel bars, as opposed to coarser gold placers where the weight of the gold particles allows the gold to settle down on or near bedrock.
Ore testing and other advice for starting up a mining operation.

The very first thing to find out...is if the detector has the ability to be ground balanced.
Unfortunately, not all the gold that we prospectors find is pretty, or appealing to the eyes. They are not all nice, bright, shiny nuggets with lots of character that carry high collector value.
