Hey mate

my understanding is its just getting enough shallow ,open cut , close to mill ounces for a decent ROI to get the finance for the mill refurb

then get the UG done with all the cashflow from that... to get to 100 koz / year

[ generally MC of miners is around 250mil MC at 100 koz / year or approx 8 times current MC ]

5+ Moz is a ridiculous amount already....

once we are back into production again im sure it will be obvious to scale more the 100 koz a year once the mega $ starts coming in... no use waiting 50 years to go thru it all... 5 times that at 500koz a year down the track seems like a much better long term goal
