Grade is relative:
"Factors like orebody depth, metallurgy, size, and mineralisation style differ wildly and play a massive part in measuring all in sustaining costs (AISC) – that’s the amount it costs an operation to produce one ounce of gold.
Sam Ulrich, director at Perth-based Aurum Analytics, says gold grades “are not the be-all and end-all”.“At the individual deposit level grade is king, but when comparing two or more deposits it is not,”
Evolution Mining’s (ASX:EVN) share of the Ernest Henry operations was the lowest cost producer, reporting an AISC of $-644/oz followed by Newcrest Mining’s (ASX:NCM) Cadia Valley operations with an AISC of $174/oz.Both these operations boast average gold grades of less than 1g/t." (yes they include base metal credits)
I'm just researching what I can but it seems reasonably close to Cadia in terms of average grade.
The economics of scale obviously come into it a lot with a porphyry deposit.
We have over 1km at .18g/tAu and 834m at .24g/tAu for example + the copper
The gold is there it just takes a lot more initial capex but the AISC should be low once set up
