niggly little doubts remain....My doubts about GOT:
absence of a reliable MRE.
GOT has published an informal estimate that does not conform to NI 43-101. Details of the modeling are obscure. The model doesn't cap grades, which is a standard practice. I looked for and didn't see info on size of the cells used in modeling, or the algorithms used for interpolation between actual data points.
Subhorizontal ore zones.
Most of illustrated 3-D modeling that GOT shows consists of multiple subhorizontal zones. Mining subhorizontal zones is challenging.
While modelling can make projects composed of multiple subhorizontal zones look good - they're hard to mine without removing a lot of non-economic material. strip ratios are high, and reliable feed of ore to a mill is tougher.
Having an NI 43-101 MRE with small cells and conservative algorithms for interpolation would really help here.
"Confirmed" feeder zone.
GOT has repeatedly said that "Colorado School of Mines "confirmed" a deep feeder zone. CSM presented a hypothesis. Only the drill will prove if the feeder zone is where GOT shows it on diagrams. GOT hasn't done much deep drilling. Another half- dozen deep holes are needed to confirm a deep feeder zone. For all we know, there' a fault or other discontinuity, down there and the feeder zone was disrupted (dislocated from the shallower zones of ore) by subsequent deformation. Need the drill to confirm the feeder zone.
What will a real MRE show?
High grade ore (good).
Probably a high strip ratio (bad).
it may assume that excavation and/or ore sorting can economically effectively separate ore from other rock before it reachs the mill.(dubious).
