I think the guesses so far are pretty close. for MRE tonnage 35mt (+/- 5mt). Average head grade is the real unknown.
I am not too concerned about this first MRE for any of my calculations as there is too much upside on the developments since data points for this MRE calculation.
I am thinking the SS will allow room too for potential upgrades based on exploration events over next year.
The PFS should have more firm direction.
If BK has early indications of another high grade economical U/G scenario, then this opens up further potential process scenarios.
Like higher MSV : DSS ratios through 2mtpa, build revenue and process experience for later ramp to 4mtpa and then reduce MSV ratio.
The further the development of KCS and a joining of the 2 bodies into a feeder zone, could well see an overall average 1% for all the DSS ore,
Scott has mentioned his thoughts months back on a DSS head grade of close to 0.9%.
Add to that 80/20 blend ratio. get it to 1.1% say
and that is 40kt Ni from 4mtpa. That is big $$$ just from Ni.
I am looking also at the potential on them utilising existing U/G infrastructure if a high grade feeder zone eventuates,
hard to see on there maps if that is possible from the existing workings, but there is plenty of examples of 500m to 1km drives shooting off from old workings to new ore bodies.Example: Leinster Persey U/G to Venus ore body or Cosmos deeps to AM5 &6 and onto Odysseus.
[This could be a major surprise to the market, watch this space, fingers crossed]
