Manganese Outlook, page-2

Good story, and yes the market seems unaware of the increase use of Mn in EV lithium-ion batteries.

The only ASX listed companies that produce Mn are S32 and OMH, and  its possible that EPM will produce in the future. GMC doesn't own any Mn mines and never will, GMC is only smelting Mn for ferro manganese. IF GMC does get DSO permission it will only be for a short time and will not be allowed once the 2 x smelters are installed.
If you want some exposure to Mn in EV lithium-ion batteries then you'd better invest in a Mn miner such as OMH, S32 or EPM
