Hard Rock 101: Breaking Rock—Part I
May 2020 by John Norman
What do you do when you’ve located a promising deposit of gold or gemstones, but it’s trapped in solid rock?
When we got set up and I started to swing the coil over a small mound, I got a good signal, faint but repeatable.
I have found gold more than 200 feet above the river. It was not unusual for nuggets of an ounce or more to be found in these deposits, but fine gold and flakes are much more common.
Many years ago I was in the American Canyon. I remembered a few details about a placer deposit there, so we decided to make a trip down and re-check some of these old workings.

...we were able to pull out close to another 3+ ounces of small, angular Silver City gold. This also included several more small nuggets, pieces of wire gold and some quartz-gold pieces—not bad for 4 days with a small sluice.
There are so many, many different types of gold pans on the market that I thought it would be worthwhile to take a look at the world of the simple gold pan.
As I arrived at my detecting location, I got all my gear and headed up the trail. I had to stop and take in the devastation all around me.
