Prospecting & Detecting

I could see lots of quartz, both loose on the hillsides and in the numerous small prospect diggings. There was a small gold rush here more than a century ago.
Entry-Level Metal Detectors for Gold Prospecting
These are entry-level machines designed with gold prospecting in mind and with the ability to handle mineralized ground and see nuggets of a grain or so in size, perhaps smaller.

VLF Detector Operating Modes
It is important to note that discrimination is a type of electronic filtering. The signal is analyzed, and depending on the discrimination setting, identified as either a target to be dug or a target to be ignored.
Old Mine Sites and New Technology
We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.
Chasing Float Gold—The Starry Night Wash
The sun was beginning to set, which put the light at just the right angle against the hillsides to where I believed that I spotted a very small dig and tailings pile up the hill near the top of the second wash.
So Where's The Gold?
...we finally got back to this exploration effort. The old works there were up above the old camp, which was very significant in size.
Metal Detector Testing Methods
It will not be any easier than on your table at home, and so testing a very small test target like the ballpoint pen can tell you immediately if a detector is suitable for looking for tiny gold nuggets.
