Large Scale Mining
Alaska to Target Rare-Earths
November 2011 by Becky Bohrer
Alaska is in the midst of assessing its rare-earth resources, an effort pushed by Governor Sean Parnell, who sees them as another example of where the US is reliant on foreign sources to meet its needs.The “Chuck It Out” Nugget
This was no ordinary nugget. It had not traveled very far from its nearby source, and that did mean a lot, as we were searching for the source of several such nuggets found during a gold rush that occurred in 1859.
Surviving The Boom and Bust Cycle
Back when I was in college, when I first started classes, the demand for new engineers was so strong that every graduate had multiple job offers without even trying.
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.
Stamp Mills
Stamp mills were a proven method of proccessing in early mining.
Lithium Fuels Hopes Around Salton Sea
The lake is at the southern tip of the San Andreas Fault, which has shifting tectonic plates that bring molten material closer to Earth’s surface. The only other part of the US known to have more geothermal brine available is on the fault’s other end in Northern California.
Nevada's Lithium Boom
When prospecting for lithium, after confirming for macro attributes through research and field work, including examination of surface geology, the main tool is an accurate lithium assay.
Prospecting for Copper—What to Look for on the Outcrop
For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
