Selectable Frequency vs Multi Frequency Detectors
I like to think in terms of “conductive mass” because it is a combination of both the conductivity of the metal and the size of the target that determine how a detector sees conductivity.
by Steve Herschbach
All About Chalcopyrite
…there are loads of different copper minerals, but a large number of them form first in the ground as chalcopyrite and then through the effects of weathering are changed into other minerals like malachite, cuprite and chrysocolla.

Detecting Alluvial Bench Deposits -- Pt II
Walking around the gulch and exploring the upper drainage, picking up different rocks and inspecting them with a good loop, and looking them up in a field guide of rocks and minerals of your region will help you understand how the gold got there.
by Reese Townes
The Goldfield Mining District -- Then and Now
In 1983, some of the ore yielded more than 2,500 ounces of gold within 30 feet of the surface. The shoot pinched to a narrow vein.

MMAC Update
This will provide the opportunity to meet with many of the members of Congress in a more informal setting at several meetings, luncheons and dinners. And we have been offered the chance to meet with President Trump’s staff.

Nevada's Lithium Boom
When prospecting for lithium, after confirming for macro attributes through research and field work, including examination of surface geology, the main tool is an accurate lithium assay.

Old Patch, New Detector
I have been detecting the area on and off since I discovered it. Every time I bought a new detector it was the first place I went to.

Calcite and Limestone
The other distinguishing feature of calcite has to do with its chemistry. Geologists sometimes take a small bottle of dilute hydrochloric acid out into the field with them because calcite reacts with acids to make a bubbly foam.
by Chris Ralph
MMAC Update
One caller wondered why he should be required to join MMAC, asked why MMAC was not a non-profit, and compared it to some kind of extortion attempt. If he had questions like these, I assume there are others with similar questions and I will address them here.

Detecting Basics: Lose the Bad Habits Not the Gold
I will make the assumption that when any of you take a detector in your hand and head out prospecting for gold you are probably anticipating finding some gold. That’s the general idea, right?
by Ray Mills
Feather River Gold
I didn’t think too much of our dredge hole and we were both considering a move when we hit bedrock. There was a good quantity of flakes and fines, but no nuggets.

Detecting Alluvial Bench Deposits
The same questions you ask yourself about gold trapping features in the present stream can be applied to the benches above the stream. Just imagine the stream at a much earlier time, before it cut its way down to the present level…

Underground Mining: Getting the Ore Out
Choosing the right method to move your ore and waste is all about making the right choices. Sometimes more than one method may be used during the life of a mine as an operation expands and grows.

From Vietnam to Wedding Bands
It’s a common symptom of gold fever for miners to be very hesitant to let go of gold they’ve found or even have it made into jewelry. I confess, I suffer from the same incurable disease!
by Ron Kliewer
Trade-Ins, Swaps and Like-Kind Exchanges
While most prospectors, mine operators and business owners are aware that “like-kind” exchanges can be an excellent way to postpone the gain resulting when any of the operation’s assets are disposed of, few give any thought to the value...

Melman on Gold & Silver
…they continue to strut around and make declarations and proclamations as if they were still in positions of power. In other words, in political terms, they haven’t “got the message” that they are now in a minority position…

The operation and techniques employed are highly successful in producing free gold with minimal work involved while maintaining an environment protection process through the use of recycled water and a settling pond.

That First Nugget
After getting all the gear together we headed up the old road that led us to an old ground sluice site. George and Kaleb were using lightweight VLF (very low frequency) detectors. I carried a newer technology unit that is just a tad coil-heavy in the front.
