What garbage you post.
That isn't a manganese ore chart, its the price chart of electrolytic manganese metal (EMM).
Obviously you don't know much about manganese, perhaps thats why you bought back into GMC.
Electrolytic manganese metal will not be made by GMC.
Just so you know the current EMM export FOB price is US$1,800 - US$1,840, down by US$210 - US$220 since the end of March.
