Gallium and Germanium in Utah
September 2003 by Edgar B. Heylmun, PhDThe high-tech industries are making use of a number of so-called “minor” metals, many of which are obtained as byproducts of copper, lead, or zinc mining. Some of the minor metals have properties that are ideal for certain applications and, in some cases, advancements in technology are being held back because of a shortage of the metals.
When I got back to my patch, every signal was a nugget, and I was burning up with the gold fever.

Metamorphic rocks such as gneiss and schist are known for their pocket gold deposits. Such pockets may not be large enough for major mining operations, but may be very rewarding for individuals or small companies. Gold-bearing quartz veins may cut gneiss or schist, but often the veins parallel the bedding, or foliation. The origin of mineralized veins, which parallel the foliation, has been kicked around for years.
Improvements in mining equipment and techniques, along with a higher gold price, make many mining properties profitable today that may not have been in the past.
Exploration for and prospecting in search of similar deposits should focus on rhyolite bodies located in fluorite-bearing areas.
It was June 6th, 1999 at 7:00 am when I started hiking to the river with my final load of dredge equipment. Hearing the flow of water in the South Fork of the Yuba River and the call of birds up and down the canyon, I added some whistles of my own just to annoy the nearby birds.
It’s worthwhile for the prospector using a metal detector to know a little bit more about the association of iron and gold as well as how iron minerals affect your metal detector.
