California's Mother Lode Quartz Veins
May 2015 by Chris RalphThe actions of the hot, ore-bearing solutions are not limited only to the deposition of material within the walls of the fissures.
Confluences of placer streams are well known as concentration sites for heavy minerals. The basic reason is that...
He found 5 to 7 feet of gravel containing half an ounce per yard. This started a rush of placer activity and several other shafts were sunk, with some large multi-ounce nuggets being found.
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
I get a lot of questions from prospectors about garnets, their value and what they tell us about the geology of some types of mineral deposits. So I thought it would be a good idea to take a closer look at the lowly garnet and learn a bit more about it.
The most obvious benches are usually near the valley floor, but they can be thousands of feet above the valley floor. Since benches were made by streams, they can contain placer deposits.
There were some exceptional times in the far-flung history of the West. Rich finds of minerals that set men’s souls ablaze. From the rich gold fields of California, men who arrived too late to find riches went searching in every direction. The trail that we will follow leads east, past the shining silver district of the Comstock Lode.
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.
