Critical Metals: Lithium
February 2014 by Chris RalphProspecting for lithium deposits can take a number of different directions, because this metal can be extracted from a variety of geologically differnet sources.
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
Because tungsten minerals are heavy, exploration can be done using stream sediment samples. Prospectors looking for gold have found scheelite or wolframite in their placer concentrates, and in some cases this has led them to make important tungsten finds.
When I was a student in the College of Mines at the University of Utah, the Verde district was used as an exploration model for “submarine volcanogenic massive sulfide deposits.” So I looked forward to visiting this district and the town of Jerome in central Arizona in the spring of 2012.
Two of the major factors affecting the profitability of a placer mining enterprise are the relative efficiency of the mining equipment, and the rate and percentage of recovery obtained while conducting mining operations.
It seemed that the preacher always gave the same answer to anyone who asked where his gold had come from. His answer was, “If you know your gold, you can find it. However, you will have to find it the hard way, the way I found it.”
...the area around Eureka, Nevada is well mineralized and seems to have a bright potential for future production of all sorts of metals.
We descended hunched over, down a long, steep, wooden staircase to the 1,000-level.
