Wyoming's Billion Dollar Nugget—The Trilogy Ends
June 2011 by David C. FreitagThe next hurdle to jump was whether the trommel motor would start again after sitting on the desert for six years without being started. The last time it had taken a three foot pipe wrench to bust it loose.
The favorable geology of the northeastern and central parts of the Seven Troughs Range are the parts most interesting to prospectors. They are underlain by a thick sequence of Tertiary volcanic rocks, mostly rhyolites and andesites.
If there is misleading wording anywhere, it will be in the sample data and in reserve/resource estimates.
The excavator or backhoe has become the tool of choice for testing placer ground. These machines are the best way to explore and sample a placer deposit if the ground is not too wet or frozen and bedrock is not beyond the reach of the machine.
After he excavates the ore down to bedrock, he goes over the bedrock with a metal detector to ensure he didn't leave any gold behind before he backfills the area.
I saw gold this summer. The kind of gold that I haven’t seen since ‘81. The kind of gold that rattles in the pan. The kind of gold that would start a stampede—even in 1898.
So you think you have an ore deposit? The work has been long and hard, but there are a few drill holes, lots of samples and assays. The data is in a reliable computer and there may be a mine at the end of the tunnel. What is the likelihood of a profitable operation? Can you raise capital for development or exploration?
The first and most important thing of the sampling process is to try to be as unbiased as possible. There is a natural tendency to select rock that looks the best—even unconsciously.
