March 2016 by Jim Halloran
The fresh material is worked and concentrated by the waves on the flat, wide beach platform. The waves wash away the lighter minerals, leaving the heavies near the bluffs and in depressions on the beach.
Critical Metals: Copper
From time to time I’ve been doing a series on critical metals and how important they are to our complex and technological society. This month we are going to take a look at copper, and how important that metal is to our modern lives.
Nevada's Silver City Gold District—Part I
The name Silver City is quite ironic as it doesn’t really fit the area’s metal production. The area encompassing the Silver City district is a great, stand-alone gold district, where the production value of gold has been much more than that of silver. Since the initial discovery of gold-bearing veins in the mid-1850s, the area has been a center of continuous small and large-scale gold production.Eastern Arizona: Gold and Base Metal Deposits Part II
In this review of precious and base metal deposits in Arizona, it is apparent that several significant mines and mineral deposits occur in eastern Arizona, and there is considerable potential for new discoveries.
The Long Road to Gold Point, Nevada
Apart from the hard rock mines, there are abundant gold-bearing placers, especially in the areas in and around Oriental Wash.

Gold is a fairly widespread mineral in the Italian Alps and in the Northern Apennines. It is found both in primary mineralization and in past and recent floods.
Diary of a Diamond Prospector
I couldn’t wait to get started. With no field budget, an assay budget of $100/year, a 1975-Ford Bronco that was a road hazard, a gas card, a topo map and full support of the director, I headed to the State Line district near Tie Siding along US Highway 287 to begin mapping kimberlite.
What Are Those Rocks In My Pan?
The placer mineral identification key is designed to answer this question. It attempts to recognize all the minerals in your gold pan concentrates.
