Prospecting & Detecting
Placer Gold Deposits of New Mexico
February 2019 by Chris Ralph
While a large number of locations have yielded some placer gold, most of the state’s placer production has come from a few productive districts.
Critical Minerals: Titanium—Part II
There are both hard rock and beach sand types of titanium deposits, but the hard rock deposits need to be at least 10 percent titanium while the beach sands often are economic with only two or three percent titanium.

Back at the entry point of the mine, we took turns slowly crawling down the slope leading into the mine portal with our metal detectors, hard hats and flashlights. The mine was hand dug and is about 75 yards long.
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.

Common Mistakes of the New Detectorist
Detecting is not very complicated and the rewards can be tremendous. The difference between success and fruitless toiling can be remedied by a few small adjustments and a whole lot of perseverance.
