Big news below.
TMI is the largest EMM producer in China. They will remove 150kt of production in Feb-Mar 2022. The whole production capacity of EMM in China is 1.2 million per year, so this is a massive gap in the market which will significantly benefit TMI's competition.
TMI has its own manganese ore from its acquisition of ConsMin (Ghana + Woodie Woodie in Aus land) back in 2016, so their lack of production won't affect the spot manganese ore market, but will improve economics for all other producers, including JMS' customers.
