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.
The Many Facets of Iron
I’ve been fascinated by iron minerals for many years. So let’s take a look at this very interesting and colorful element.
Why Did This Silver Mine Close? - Pt III
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 Batteries Metal Rush
There is a major change coming in the economy of the world and now is the time for prospectors and miners to grab a ticket and get on board.
