RE:The biggest Glencore closed Mutanga over a year ago in an attemp to cut world cobalt supply and get the prices up. It did not work.
Glencore has had Katanga's cobalt production shut down for a new leach process that is 2-3 years behind. Delay after delay. Also limiting world cobalt supply.
It then did a massive 2B share diltion that gave Glencore 96.9% of the shares and the retail shareholder got ZERO in the end. Katanga is now privately owned by Glencore.
These two mine alone are 40% of world production.
The fall 2017 winter 2018 cobalt price spike was caused by cellphone demand. It will not be repeated.
Dan Gertler, a man sanctioned by both the USA and Russia made 2.83 Billion in comission by getting his buddy the then president of DRC to sign a deal with Glencore for these mines .
Just a little info on how dirty a game cobalt has become.
