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.
In this case, signs of gold were found at the bottom of the alluvial and then traced in a triangle up the face of the mountain until they stopped—that is where the digging began.
The actions of the hot, ore-bearing solutions are not limited only to the deposition of material within the walls of the fissures.
…if you are game for digging in and learning more about the intricate details of how gold deposits form, then let’s jump right in.
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
Has your experience ever led you to wonder why some gold is deposited on bedrock and in crevices, while other gold is not? We’re going take a deeper look at this and see what we can figure it out.
Gold is a fairly widespread mineral in the Italian Alps and in the Northern Apennines. It is found both in primary mineralization and in past and recent floods.
…it was immediately evident the previous owner had not been using a detector. During just a few months of working the dumps part-time, he recovered gold in quartz specimens valued in excess of $40,000.
