Metal Detecting Old Hard Rock Mine Dumps
May 2018 by Chris Ralph
The type of mine dump that is best for metal detecting are the ones that consist of mixed sizes of rock and are located near some sort of excavation, commonly a shaft or adit. Sometimes the piles located along a trench dug by the miners can be productive as well.
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.
Talking Metal Detectors with Brent Weaver of Garrett

Following Clues to a Lost Gold Deposit—The Northern Extension of the Cedarberg
Last month, in “Following Clues to a Hidden Gold Deposit,” I ended the article with the direction that we were on the hunt! We were getting prepared and ready to roll with our detectors, then snow came, and lots of it. We had already found the seam diggings mine on the mountainside in wild, rough brush and trees. It had been well hidden.
Bedrock Gold: When It’s There and When It Isn’t
Has your experience ever led you to wonder why some gold is deposited on bedrock and in crevices, while other gold is not? We’re going take a deeper look at this and see what we can figure it out.
