The US is seeking to procure cobalt worth up to $500 million for defence stockpiles amid the country's move to boost its critical mineral supplies.
Companies have been scrambling to source rare earths after China imposed restrictions, leading to a 75% drop in rare earth magnet exports from the country in June and causing some auto companies to suspend production. US President Donald Trump in March invoked emergency powers to boost domestic production of critical minerals as part of a broad effort to offset China's near-total control of the sector.
In July, it was reported that the White House tapped a former mining executive, David Copley, to head an office at the National Security Council focused on strengthening supply chains. According to the tender document published by the US Department of Defence (DoD) and the Defence Logistics Agency (DLA) on Wednesday, they are looking for offers for alloy-grade cobalt of about 7 480 t over the next five years.
Cobalt, mostly imported by the US, is used in batteries, a component in nickel superalloys for high temperature sections of jet engines and industrial gas turbines, among others. However, the DoD was seeking offers from only three companies - units of Vale in Canada, Japan's Sumitomo Metal Mining and Norway's Glencore Nikkelverk.
The document also said the purchase amount could range from between $2-million and $500-million in the five-year period.
