Compare the pair:
GXY FOB cash costs: US$447/dmt
GXY CIF: US$352/dmt
PLS cash costs: AS$487/dmt (net of Ta2O5 by-product credits)
PLS CIF: US$352/dmt
PLS hurt a lot too. They had an operating loss of A$63Mil and a net loss of A$84Mil for HY20 and HY21.
Putting things in perspective might ease the pain.
