Bezos, Bloomberg and Gates back revolutionary exploration tech

A new startup backed by several tech heavyweights is using revolutionary big data analytics to find new, ethical cobalt deposits in reliable jurisdictions.

Some 60 percent of the world’s cobalt, as a by-product of copper and nickel mining, is located in the Democratic Republic of Congo, which doesn’t exactly have an excellent track record in areas such as child labor, to mention just one. Calls for finding a more ethical way to source cobalt and other battery metals have been numerous, but until now, following them has been problematic because of the lack of alternatives.

However, the financial backers of KoBold Metals startup, among them Bill Gates, Ray Dalio, Jeff Bezos, and Michael Bloomberg, seem to believe technology has advanced sufficiently to make it possible to tap hitherto undiscovered cobalt deposits outside the DRC.

Wondering at that word 'ethical' there. Whose ethics do they mean?
