I recently found myself wondering what would be the ultimate prospecting adventure. What would be the most amazing thing if I had no restrictions or limitations?
Small-Scale Processing of Hard Rock Ores

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.
All About Garnets
I get a lot of questions from prospectors about garnets, their value and what they tell us about the geology of some types of mineral deposits. So I thought it would be a good idea to take a closer look at the lowly garnet and learn a bit more about it.
Tips on Crevicing for Gold
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.
Huge California Nugget A Hoax

There's a First Time for Everyone
...day one was like watching the Gold Rush television show. He furiously worked the nozzle in an up and down fashion that resembled Jack Hoffman sitting on a backhoe.
Detecting Alluvial Bench Deposits
