Ann: OZL: OZ Minerals extends its Offer for Avanco, page-57

OK have done thanks, I was looking at the wrong number so ignore that.

AVBs lowball scoping study figure is 85435oz x 11yrs at LOM of $862 asic cost. = $409mil
They also say pre tax Npv of $231 mil. lowball Npv $172 mil

None of this is definitive though, discounts need applying for the risk in the numbers, and length of time and effort it takes to get the money out of it to get fair price.
To me you guys are looking for all the potential profits that might eventuate for well over 7yrs out, based on maybes. You got leave something for OZL they've got to fund it all.
