Longread of the day: using data science to mine cobalt

Via Bloomberg: 
Late in August, at a precisely specified point in the low Arctic, a geologist named Dave Freedman stood in a raw wind and a limitless expanse of tundra and began to thwack with a sledgehammer at a rock outcrop jutting up from the soil.

Freedman, 29, works for a company called KoBold Metals, and the process that had brought him to this pair of GPS coordinates in Quebec’s far north was complex. But the rock had had its own journey. Before it was rock, it had been magma in the Earth’s mantle, part of a molten tongue tens of meters wide that had welled up as two tectonic plates spread apart 1.85 billion years ago.

Lots of interesting chemistry within.
