interesting

Seems ozl were selling their metal using provisional pricing, so they get paid the current price but when the metal gets shipped and arrives they then get paid more money if the price has risen or they have to pay money back if it has fallen.

They got caught big time with the falling prices as it seems they hung on to the ore waiting for prices to recover but they only got worse.

Here is their table of provisional pricing
Zn 276k $US1890
Cu 11k $US7955
Pb 27k $US1920

They most likely had to pay back about $3000 ton copper

$600 ton zinc

$800 ton lead
