Butte, Montana—The Richest Hill on Earth
December 2017 by Chris Ralph
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.
There are literally thousands of abandoned wasterock and ore dumps that dot the United States that could hold many tones of strategic metals.
Let’s take a look at diamonds and diamond mining and see how they form, how they are used beyond just jewelry, and what leads geologists to find diamond deposits.
I am going to keep to the basics of surface indications and visual clues in the rocks and minerals themselves that help me find gold-bearing veins in this classification of deposits.
The Candelaria area is of interest to prospectors not just for silver, gold and other metals, but also for the beautiful gemstones found there.
The areas that were mineralized with the bedded ore were huge and vast tonnages were indicated, although they had no idea at the time.
I couldn’t wait to get started. With no field budget, an assay budget of $100/year, a 1975-Ford Bronco that was a road hazard, a gas card, a topo map and full support of the director, I headed to the State Line district near Tie Siding along US Highway 287 to begin mapping kimberlite.
