Right now from leapfrog modelling just what they have released (and others have done this also) he's got 100Mt resource in the bag IMO...The on-going drilling on TA1 currently is probably to extend the system to depth to ~400m assuming the continuity of these fat zones remains. This on-going drilling could easily bring an additional 30% more inventory into the TA1 volume they have already defined (note another user posting satellite photos of drilling stepping out looks to be targeting these deep fat zones in the south).

I wouldn't bother to drill beyond a plunge of 400m, any more plunge is going to eat into the strip ratio and will not come into the OP reserve anyway. You always want to leave some upside in the ground for later, continuing add value from areas TA2 & 3 drilling relatively shallow holes is low risk best return on time and money. Tony's got this, leaving 100m fat intercepts open at depth is an excellent prick tease for any potential TO that will likely flood across the desk post maiden resource.
