Mining on the Comstock Lode
July 2014 by Alex DolbeareEven with the decades of mining and exploration, much of the Comstock is still underdeveloped and its potential not fully tapped.
Each specimen is carefully examined to determine if it would be beneficial or not to use an acid treatment to reveal more of the gold.
This explains the large difference in particle sizes between placers and hydrothermal lode deposits, but also means that while the mining may be similar in some cases, the sampling and recovery techniques are usually quite different.
In part one of this two-part series on gold in Guyana, I describe artisanal mining efforts currently winning alluvial gold from small-scale placer operations located along the lower Puruni River and its tributaries.
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.

Augers can be used effectively for placer exploration with certain limitations.
This is the point where you might ask, “What do these types of contracts typically look like and how are they negotiated?” Well, that is the topic of this month’s article.
