At first, I tried to shift things around, but then a hand with a rock would appear, so I would stop trying to adjust my gear and grab the rock to keep things moving.
The excavator or backhoe has become the tool of choice for testing placer ground. These machines are the best way to explore and sample a placer deposit if the ground is not too wet or frozen and bedrock is not beyond the reach of the machine.
When we last heard from Ernie, he was still in Honduras and we were anxiously waiting to hear how the set up and training went at the mine. It got a bit complicated after that.
The favorable geology of the northeastern and central parts of the Seven Troughs Range are the parts most interesting to prospectors. They are underlain by a thick sequence of Tertiary volcanic rocks, mostly rhyolites and andesites.

Depending on the ore and if significant sulfides are present, a hard rock miner may be able to get away with simply using a flux to digest the other minerals that may be present.
