RE:RE:RE:They can only hopeWait...is this where you state it's all refractory gold again? The engineers are working out the cut off and there's absolutely no set grade (though you pretend there is)....if you recall the first cut off for block cave was based on .5/ton and then they bumped to up substantially to 1gm/ton and they continue to play with that cutoff...they don't even know...so how do you know? You don't "oh great one".
