History & Geology
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
A treasure-seeking young man whose name will forever remain anonymous made the months-long journey either over land or by sailing ship to California after word spread about the gold strike in 1849.
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.
In this second part on cobalt, I will take a look at the various types of cobalt deposits and how you can prospect for them. Who knows—perhaps the next big cobalt strike will be yours.
...these nuggets have not traveled far from the lode because the golden wire lattices would have been torn apart or flattened during weathering of rock and deposition by violent stream action.
The gold is all for sale. Just one tiny coin alone could go for $1 million because of its combination of rarity and the history behind it...
Not all of these slides and debris flows will produce results, but if you search for these while prospecting in your gold producing areas, then you can increase your odds of finding new gold.
While some future cobalt will come from recycling lithium batteries and other products, the coming huge need for cobalt is virtually a perfect storm of heavy demand and insufficient supply.
While the bullion value of the nugget is already substantial, the size and rarity of the Ausrox Nugget combine to make its worth invaluable in the collector market.
I recently had the opportunity to spend a day exploring around Butte, Montana and was amazed by the amount of mining that has taken place there. The old-timers called Butte “the richest hill on earth” and had pretty good reasons for doing so.
The nugget sat there in plain sight, though it was covered in dirt, while hundreds of people had passed that way every day.
On our last trip, we brought ropes and went down the first waterfall forty vertical feet, only to be confronted by a second, sixty-foot-high, overhanging waterfall that emptied into a slot canyon.
We just completed a trip to another river, and yes, there was definite movement and redistribution of gravels, and other prospectors have seen this as well.
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.
