Prospecting & Detecting
Northwestern Alaska Mineral Resources
February 2016 by Steve Herschbach
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
Drywashing for Fine Gold
When working fine gold placers with a drywasher, there are some natural variables that can be beneficial as well as others that can be a hindrance to achieving good recovery.
Gold in Unlikely Places
Detectors have been around for decades now. And with thousands of them swinging, many of the best or at least most likely nugget places have seen a swinging coil. The part that amazes me is that so many nuggets still get pulled out of these seemingly pounded places.

Is It Time for a Change? New Ways to Find More Gold
The old report I read indicated all they ever did was dig some trenches and take samples. It sounded to me like a good place to take my metal detector...

Perhaps the most notable thing about skim placers is that they form on the top surface of gravel bars, as opposed to coarser gold placers where the weight of the gold particles allows the gold to settle down on or near bedrock.
The Essentials of Dry Washing
Most dry washers have a feed rate adjustment. It needs to be set so that the material flows evenly over the riffles and does not bury them.
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.
