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.
Even as late as 1906, Delamar was second only to Tonopah and Goldfield in production outshining many better known areas. Since the first discoveries, more than 700,000 ounces of gold have been produced from the mines here.
…if you are game for digging in and learning more about the intricate details of how gold deposits form, then let’s jump right in.
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
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.
Narrowing down a closure date will allow you to check the commodity price during that time and possibly confirm that a low price, rather than a lack of ore, was the driving force that closed the operation.
The large buckets were favorable for the type of ground worked. The gravel was tenacious and compact, due to the existence of irregular pockets of clay.
