Broken Hill global cobalt province., page-860

Seven years ago, revelations about dire working conditions in Congo’s informal mining sector vaulted into the world’s headlines after Amnesty International and the Congolese rights group Afrewatch published a report detailing deaths and injuries among the countless children working in small-scale, hand-dug mines, often in manually carved tunnels that frequently collapsed and buried the young miners alive.Since then, global appetite for Congo’s cobalt has grown sharply, mostly driven by a dramatic increase in the demand for EVs. Nearly 90 percent of the cobalt produced in Congo, home to half the world’s reserves, goes into batteries, including those used by American, French, German, Japanese and South Korean automakers. Demand for cobalt is projected to increase 20-fold by 2040, according to the International Energy Agency. QUOTE
The market is vulnerable could change at any time IMO
