Prospecting & Detecting
Sampling Placer Stockpiles
August 2013 by Jim Halloran
Sampling other people's stockpiles or dumps has some inherent risks that sampling undisturbed ground does not have.
Procuring Mine Owner Permission at a Mine Site
The first experience involved an overgrown gold mine operated during the 1880s. A razed mill adjoined the mine and could be glimpsed from the isolated public dirt road I was traveling.
Mud Men: Pocket Miners of Southwest Oregon Part III
The amount of gold in the traces from the low-grade scattered veinlets may be much more than the traces from the small but rich pocket, at least until the pocket hunter closes in on the rich pocket. Further confusion arises if the prospector stumbles across a placer deposit on one of the higher peaks.
Drywashing in Black Canyon, Arizona

Ganes Creek Hits 10 Years—Part II

Iowa Hill District
For the last two years we’ve held a hands-on prospectors training session in the Iowa Hill district of California’s Mother Lode country as a part of our Gold Prospecting and Mining Summit event. Because of this, I thought it might be good to take a look at the history, geology and opportunities that the Iowa Hill district still offers to the individual prospector.
