Prospecting for Pegmatites
…in some cases pegmatites have produced individual mineral crystals that are enormous, attaining lengths of over 40 feet long, and many of the world’s largest mineral crystals are examples that were found within pegmatite 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.
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.When Legends Were Made and Fortunes Found
Sylvester Smith and his younger brother Nathan were among this group who rode and led their Indian ponies, while climbing the rugged Salmon River breaks and rockhewn mountains, looking for a path that would lead them up and over the uncharted wilderness.
Benches and Fossil Placers
Unfortunately for us mortal humans, we have a poor perspective on geologic time. When we look at a landscape such as a stream valley, we see it only in two, or at the most, three dimensions. We have poor comprehension of the valley’s fourth and most important dimension—time.
Alaska Gold: Lisianski Inlet's First Bonanza
In 1967, a local resident showed me a pouch of small gold nuggets and flakes. Several years later I asked the same person where that gold was found. He responded, “From the streambed below the old stamp mill at Apex.”
The Mineral Range Districts of Utah
Most of the commercial mineral deposits are on the south and southwest part of the range between Minersville and Milford, though small amounts of gold and silver have also been found in iron-rich outcrops in the basalt to the south of Milford.
