Exploring Iron Oxide Copper Gold Deposits
November 2017 by Chris Ralph
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.
Has your experience ever led you to wonder why some gold is deposited on bedrock and in crevices, while other gold is not? We’re going take a deeper look at this and see what we can figure it out.
...we will continue our examination of the rich streams and mining districts, and then take a look at some of the big nuggets that have been found here.
There are many prospects within the known mineralized area and along the margins of the mineralized area that should be examined for gold and silver.
Epithermal deposits form in the ground at shallow depths. They are popular with prospectors because can yield very rich deposits and they are widespread in the Western US.
The Candelaria area is of interest to prospectors not just for silver, gold and other metals, but also for the beautiful gemstones found there.
We have to remember that the earliest miners were not geologists, but came from a variety of backgrounds. Their survival depended on finding enough gold so they worked hard and adapted to whatever challenges these new areas presented.
There is reason to believe these stream valleys are still rich with gold, silver and copper.
