The Madonna Nugget
October 2013 by Joe ChmielIt was down deeper than I expected for surface trash. It wasn't until I was down six inches that the target screamed from my scoop.
Watching for these areas is one of my primary targets during the winter. It doesn’t take but a few inches of the surface moving away to give a fantastic target response that you didn’t hear prior to the washing of the surface.
We decided to run a detector over each piece. If we got a decent signal we placed the piece into a high-grade pile and the rest went into another pile to be worked on later. This high-grade pile wasn’t that large—maybe 25 pounds...
Then I came to a section of recently exposed gravel that looked unworked. Water seeped out all around, making the ground beneath a sea of slick mud.
From this I inferred that engine 2 had a carburetor problem. In this article, I discuss the specific engine/carburetor problem, and the surprising solution to this problem.
Micro blasting can be used to take down hanging rock, separate minerals from overburden, and collect gemstones and other high-value product with minimal damage.
…as an academic argument, when mated to the appropriate engine, is the pump really moving water at the rate of 400 GPM?
