At the very minimum they have established that there is a high quality vein underground a few kms from the pit they will be digging, the extension to mine life alone from having a high grade underground mine developed for when the T3 is done is done will add a decent chunk to the npv of that project, from eyeballing the cores there will be a vein to follow with 5-10% copper in it, that is worth sinking a shaft for or even running an adit out from the bottom of the T3 pit which is actually not that far away, lots of options, need to get the t3 plant set up and expand out from there ....
