December 2016 by Chris RalphYears later I returned with a new detector with a smaller coil and detector technology more sensitive to smaller nuggets. I found my first nugget within five minutes. I had a second five minutes after that.
Every year there are large nuggets found by the diligent, and occasionally by the lucky newbie.

…for a few hours, we fervently dug for gold. After we did a cleanup, I couldn’t believe the amount we got.
This year was a test. We had never done anything like this before, yet we grossed $30,000 in the short time we had to mine.
Depth is not an issue unless the site is thoroughly cleaned of shallow trash, and it is far easier to isolate and remove targets using a small coil in a target rich location.
The right speed accumulates only the heavy materials and allows all of the lighter stuff to flow through. This optimum speed is dependent on the size of the gravel you need to move through the system.
On our fourth trip, we finally reached the top edge of the old hydraulic pit, and it was monstrous.
