<<Contrary to what letter writters and others say, the Carlin Trend could always be assayed. But when the feds kept the price of gold at $35 an ounce, there was not much point in trying to produce.>>
Hello thall, I agree with you that when gold moved above $35 it caused renewed exploration. This happened in the mid 1970s, Carlin did not start to develop until the early/mid 1980s
To my knowledge, Livermore with Roberts discovered the first find in 1961.
Although both believed gold was there before this. It was not well known in
the industry and Nevada started out very small. Only approx. 250,000 ozs.
were mined in 1980 and gold was much higher than $35 for many years.
Production went from about 1 million in 1985 to over 7 million ounces last
year. This is when Carlin started coming in it's own
Leaching technology was not conventional in the early 1980s and whether
they had it in South Africa or did some on copper, it was pioneered in North America in the late 1970s early 80s for gold. Glamis Gold was one of the first, along with work from a couple gentleman at what I remember as the U.S. Bureau of mines or Nevada Bureau.I would have to spend some timing digging to find their names. There is quite a bit of information on Nevada, at the Nevada Bureau of Mines web site, I am not sure of the exact URL, a search should find it. It may have this information, but I don't remember, the web site is very
extensive.
There was also a write up in USA today, about a year ago that talked a bit about the Nevada gold rush and development.
