It's a good question and a very hard one to answer.
AIC will depend heavily on grade, hence the reason why AB is peppering those high-grade veins at Ricciardo.
A relatively low strip (less than 10:1) open pit with a mined grade above 2.5gt should be extremely profitable to mine at today's gold price.
If processed at Golden Grove the gold would be sold as a concentrate.








Note that these are all just spit ball estimates.

Silverstone and Silverstone North reserve will likely be above 2.5gt
Silverstone South and Eastern Creek closer to half that at 1.5gt.
M1 has the potential to have a reserve in excess 3gt (subject to further drilling success).
Windinne Well reserve could be slightly lower at say around 2.5gt.
Those 6 pits alone could go pretty close to covering that 300k reserve estimate IMHO.
