History & Geology
Gold Circle (Midas) Gold District
May 2021 by Alex Dolbeare
Many prospectors thought that Nevada was all prospected out following all the rich discoveries of the 1860s and 1870s, and what was there to be found had already been found.
Eolian Placer Gold
I would first like to mention that I am not a geologist. I have, however, spent the last 8 years intently searching for gold nuggets with a metal detector. I have found gold in numerous locations, and in several different types of gold deposits.
Enrichment of Mineral Deposits by Weathering—Part I
The exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.All About Quartz—Part I
One of the first minerals most prospectors learn to recognize is quartz, because, in the right circumstances, it can be an excellent indicator mineral for prospectors. Quartz is common, easy to identify, and is often associated with gold and other valuable metal deposits.
Preserving the True History of the Ivanhoe
My partner had the contacts and it wasn’t long before we had an agreement in place and the company had a geologist on site. I recall a time when he was getting the lay of the land, so to speak, and he broke off a rock sample and inspected it with his magnifier.
The Miner’s Switchback
Common thought is the switchback slows the velocity of the rushing water and gold drops out from the cut bank to a fill gravel bar within or below the switchback. I am not going to disregard that model; however, I hope to improve upon it.
Liberty and the Phoenix Mine
Liberty, Washington is located in the mountains near Yakima and Ellensburg. There is nothing much in Liberty except for about 20 houses on patented mining claims and a lot of dry holes.
Large Gold Deposit Types
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.
