Researching Mineralized Areas
December 2015 by Chris Ralph
There are a load of ways to do research, and I’m going to talk about how I do it—maybe you’ll get some ideas that will work for you, too.Sierra County Gold—Part I
...this county contained some of the richest placer ground found in all of California and still produces some pretty impressive finds to this day.
Conrey Dredge No. 4—Part II
These were the men who periodically picked up the gold amalgam from the tables and sluices in the dredge, processed it, and transported the gold ingots to the railroad express office in Alder. Their trustworthiness must have commanded a prominent wage.
Gold in Quartz
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.
Alaska Gold: Lisianski Inlet's First Bonanza
In 1967, a local resident showed me a pouch of small gold nuggets and flakes. Several years later I asked the same person where that gold was found. He responded, “From the streambed below the old stamp mill at Apex.”
The Batteries Metal Rush
There is a major change coming in the economy of the world and now is the time for prospectors and miners to grab a ticket and get on board.
Ancient River Channels of Trinity County
Trinity County is located in the far northwest corner of California and stirs up many different memories for those who have been there.
Gold, Quartz & Chalcedony—Part II
The specific gravity of chalcedony is 2.58 to 2.64. This is slightly lower than coarsely crystalline quartz because of slight porosity in chalcedony. Being so light, it will easily wash out of a gold pan.
