In the “toolbox” of most every prospector there are certain tools that we tend to use consistently for a variety of reasons. Have you ever noticed that tools and equipment tend to wear out, rust and fall apart whether we use them or not?

As I started walking down to the river one chilly morning, the mist was hanging over the calm portions of the water like a white cotton blanket. This scene got me to thinking about why the river was like that—the deep pools, boulder fields, gravel bars, the effects of how much water was moving at any given time along the watercourse—and most of all the relationship all these things have on where I will be able to find gold.
Each specimen is carefully examined to determine if it would be beneficial or not to use an acid treatment to reveal more of the gold.
The gold was very chunky and much of it had quartz attached. Even back then I knew that the gold was very close to its source.
There are many smaller old hard rock mines out there—more than you might think. There are some small hard rock properties that are even open to be claimed if one does the right amount of research to find them.
