Understanding Geologic Deposit Models
May 2008 by Chris RalphGeologists have long noted the similarities of certain types of mineral deposits all across the globe. Similar minerals, similar country rocks, and similar grades of mineralization may occur in several different parts of the world.
Ore testing and other advice for starting up a mining operation.
Many of the Sixteen to One’s challenges arise from its unusual geology and the pocket characteristics of the ore deposits.
Outside of Butte, Montana, going north on I90, you’ll pass through a landscape where the old Anaconda mining company processed thousands of tons of ore twenty years ago. We meant to fish in the vicinity of this historic mining district though we knew it is a Federally classified Superfund site for reclamation now.
Lower Coon Mountain is located in the Klamath Mountains, some 10 to 15 miles east of Crescent City (pop. 4,400), which rises to an elevation of 2,841 feet. It is heavily forested except for a few areas that are underlain by serpentine. The mountain, which trends northeast, is bounded on the north by Craigs Creek, and on the south by Coon Creek.
After getting all the gear together we headed up the old road that led us to an old ground sluice site. George and Kaleb were using lightweight VLF (very low frequency) detectors. I carried a newer technology unit that is just a tad coil-heavy in the front.
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
Located 23 miles south of Libby, the land surrounding the Libby Creek area has been of interest to prospectors since the early 1860s, when it was home to up to 600 miners working at a camp known as Libbysville.
