Prospecting & Detecting
Prospecting Knowledge -- Pass It On!
May 2017 by Ray Mills
I had two of the guys go down into the creek and each one picked out a small island of bedrock. I had them detect their piece of bedrock and then gave a critique to all on how they did.
Gold in the San Francisco District Oatman, Mohave County, Arizona
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
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.
Diamond Prospecting in Indiana
My first personal experience with placer diamonds was on a gold prospecting trip in Indiana about 8 years ago, when a fellow prospector was cleaning his gold concentrates.
Pumping Water With Solar Power
Solar energy can be used for any size placer or hard rock mining operation. It is most practical for small and longer-term operations provided your mine is not located in a dense forest.
Mining Journal Receives Honor
For the 20th consecutive year, ICMJ’s Prospecting and Mining Journal was voted “Prospecting Magazine of the Year”...
One Potato, Two Potato...
Normally the detector he was using would sound off with a definitive high-to-low tone when passed over a piece of gold, which distinguished the gold from the many high iron content "hot rocks," but this one was different...
Pros and Cons of Big Detector Coils
Years later I returned with a new detector with a smaller coil and detector technology more sensitive to smaller nuggets. I found my first nugget within five minutes. I had a second five minutes after that.
