Heavy Glacial Rocks and Gold in the Midwest
December 2013 by Chuck LassiterOver the years, I've noticed a pattern in the type of rocks associated with the best gold deposits in Midwestern glacial gravel.
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.
So let’s dive in and see what I can do to convince you that this is the year you should be out staking your own claims.
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
I knew the nuggets got into the nugget patch somehow, I just had to figure out how and from what direction they came.
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.
Even with my favorite top-of-the-line gold detector there were several false digs. Many of the hot rocks gave a solid signal that was too much like a nugget to ignore. After trying several tests I just dug everything because it is better to be safe than leave a big, deep nugget for a more diligent gold hunter.
…it was immediately evident the previous owner had not been using a detector. During just a few months of working the dumps part-time, he recovered gold in quartz specimens valued in excess of $40,000.
