Ann: Mt Thirsty Cobalt Project Scoping Study, page-13

Comparison with eCobalt Feasibility Study

CNJ/BAR   eCobalt
Cobalt production p.a.    1,280 tonnes   2.4 mill. lbs
Over Mine Life   27,000 tonnes   31.8 mill. lbs
Mine Life 21 yr   12.5 yr
NPV    AUD290M after tax USD135.8M
Discount Rate 8%   7.5%
IRR after tax    21.5%  (4-yr pay back) 21.3%
Co price over mine life    USD33/lb approx   USD26.67
Opex AUD43/tonne USD5.05/lb
Initial Capital Cost AUD212 mill.   USD186.7 mill.
  
Worth noting is the recovery rate at Mt.Thirsty via agitated leaching. The SS assumes 73% but a range of 73 to 80 is noted as well as plans to optimise.

There is much interest in the projected cobalt price. For the 21-yr mine life, 33 is used for MTT.
eCobalt assumes approx. the current price which, they assume, will hold for the 12 years of mine life.

A CRU research study has global cobalt demand at 96,000 tonnes in 2016 increasing to 166,210 tonnes by 2026. CAGR will be 6% initally then 4.1% in the next decade.
