Searching For Lithium Deposits With Satellites (economist.com)

A group led by Cristian Rossi, an expert on remote sensing, is using satellites already in orbit to detect and map geological and botanical features that might betray the presence of subterranean lithium. Though satellite prospecting of this sort has been employed before, reads a new report in The Economist, to look for metals such as gold and copper, using it to search for lithium is new. From the report, which may be paywalled: The searchers are not searching blind. They know, from mining records dating from the mid-1800s, that there is lithium in Cornwall's rocks. Those records tell of underground springs containing salts of lithium -- at that time quite a recently discovered element. Back then these springs were seen, at best, as curiosities, and at worst as flooding risks, because there was then no market for the metal. Today, there is. In particular, lithium is the eponymous component of lithium-ion batteries. These power products ranging from smartphones to electric cars, and are being tested as a means of grid-scale electricity storage which could make the spread of renewable energy much easier. No surprise, then, that prices have been rising. In 2008 a tonne of lithium carbonate cost around $6,000. Now it would set you back more than $12,000.

Where's the story about cobalt production? That's a bigger bottleneck than lithium.

There are alternatives to cobalt, such as manganese, which is plentiful. There is no substitute for lithium.

New? Not even.

Nope, I've been using ASTER and LANDSAT 7/8 for years to do mineral-specific prospecting. I just finished a trip out to Lavic near the 29 Palms bombing range hunting boron and lithium minerals.

These guys are what's new, not the technology nor technique.
