"Tantalite concentrate will be packed into 205L drums, sealed and exported via Fremantle in standard shipping container."https://www.asx.com.au/asxpdf/20170711/pdf/43kkjk14z4kr79.pdf
Haven't figured out yet which ship from the Fremantle ports: https://www3.fremantleports.com.au/vtmis/dashb.ashx?db=fmp.public&btn=ExpectedMovements
It might be AAL Nanjing (General Cargo) which is currently docked in Geraldton (part of Fremantle Ports network)?
