ICMJ Visits Grass Valley, California
March 2023
Exploring Iron Oxide Copper Gold Deposits
The excitement over IOCG deposits began with the discovery of a monster deposit at Olympic Dam in Australia in 1976. The discovery was accidental as the operator was searching for strata-bound copper deposits.
California's Mother Lode Quartz Veins
The actions of the hot, ore-bearing solutions are not limited only to the deposition of material within the walls of the fissures.
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.
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 Downieville Gold District
Many locals are just waiting for California to allow dredging once more, especially with the current gold prices. There are still plenty of good opportunities for prospectors in this area, just as it has been for so many years.
Alaska: Kodiak Islands Mineral Resources
The fresh material is worked and concentrated by the waves on the flat, wide beach platform. The waves wash away the lighter minerals, leaving the heavies near the bluffs and in depressions on the beach.Why So Much Gold in Nevada?
Nevada produces about 75% of all the gold mined in the US. This means that all the other 49 states combined only produce 25%, and this includes California, Alaska and Arizona.
