Detecting Clay Seams
November 2015 by Ray MillsBecause the old timers were so good at locating the better paying deposits—most of them along clay seams in this particular area—it makes good sense to try and locate these clay lines at old mining sites.
I was able to remove the gravels with the assistance of a crowbar and I scooped them up with a garden trowel. This gravel contained over a pennyweight of gold and there were several 2-grain and 3-grain pieces…
The box sat in a hallway and employees began using it for impromptu cricket games, no knowing what it contained.
When everything is still dry, one of my favorite methods of prospecting is using a straw to blow out small cracks and crevices that dot the exposed bedrock along a stream.
Over the years, I've noticed a pattern in the type of rocks associated with the best gold deposits in Midwestern glacial gravel.
We split up in order to cover a larger area and found good color almost everywhere. The bedrock was shallow on both sides of the river, but the inside bend was where we concentrated our prospecting.
“Metal detecting is not a social function.” So said a good friend of mine. And it’s true. But that’s not to say the benefits of having a prospecting partner don’t outweigh those of being alone.
I have a bunch of ideas about what to do in the near term and then other thoughts about what things might look like a few months from now when I hope the situation will look a lot better.
