Large Scale Mining
Gold Ores of the Delamar District, Nevada
August 2014 by Chris Ralph
Even as late as 1906, Delamar was second only to Tonopah and Goldfield in production outshining many better known areas. Since the first discoveries, more than 700,000 ounces of gold have been produced from the mines here.
Great Panther Silver
The company acquired the Guanajuato Mine Complex in 2005, and since that time they have carried out extensive drilling programs, both from surface and underground, with particular emphasis being placed on the Cata Clavo Zone.
Prospecting for Copper Ores—Part I
Copper is one of the metals that form the backbone of our modern civilization. Copper is an essential part of every computer, cell phone, automobile and household appliance.

In the simplest sense, drills can be divided by their mode of action—percussion, rotary or a mixture of the two.
Who is a Qualified Person?
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 Snapshot
Once all the numbers from all the samples and water tests are compiled, a snapshot of the performance of each tank in the process circuit can be seen side-by-side.
Mining on the Comstock Lode
Even with the decades of mining and exploration, much of the Comstock is still underdeveloped and its potential not fully tapped.
