Nevada's Silver City Gold District—Part I
March 2016
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.

March 2016
The exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.

March 2016
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.

Just prior to our press deadline, we learned that a bill had been introduced in the Idaho House of Representatives to redefine suction gold dredging as a preferred use in public waterways in Idaho.

...we may now be witnessing the onset of a major turn toward a period when precious metals investments outperform conventional markets as the Dow and S&P 500 now appear to be turning toward the downside at the same time when gold and silver are showing signs of rallying.

The Art of Underwater Nugget Shooting
February 2016
There is a surprising amount of detectable gold under the water’s surface. The right tools make it much easier to find, and with a little patience and practice you can take advantage of this underappreciated bonanza.

Gold in Quartz
February 2016
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.

Northwestern Alaska Mineral Resources

Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.

Carbon, activated charcoal, or “char,” as some old timers refer to it, can be an assayer’s nightmare.

Determining the Amount of Gold in Rich Ores

This is just the type of specimen that could have been easily ignored by the old-time miners. It felt a little heavier in my hand than a chunk of quartz of that size ought to have been.
