Nevada's Silver City Gold District -- Part II
May 2016 by Alex Dolbeare
...this district has had a continuous life of gold mining and milling that spans 150 plus years, and it appears that it will keep pressing on for many more years of production.
The steeper the gradient is, the more potential erosive power to move gold and other bedload sediments, and the more power to remove obstacles to flow.
I recently had the opportunity to spend a day exploring around Butte, Montana and was amazed by the amount of mining that has taken place there. The old-timers called Butte “the richest hill on earth” and had pretty good reasons for doing so.
The holes were overloaded with explosives, but I didn’t know it. I was just a green mining engineer fresh out of school and told to watch as the experienced miners set the charge.
Contacts, faults and zones of weak rock are all places that can act as a pipeline to convey gold-bearing fluids, leading to valuable deposits.
I’ve been fascinated by iron minerals for many years. So let’s take a look at this very interesting and colorful element.
The other opportunity that I see is in seeking unusual types of deposits. Specifically, the prospector would be searching for the stuff no one (or almost no one) is searching for. These deposits are effectively hiding in plain view.
