Pre-feasibility Interview – InvestorIntel

On 12 May 2015, Frontier Rare Earths Limited (OTCQX:FREFF) (“Frontier” or the “Company”) announced the results of a Pre-feasibility Study (“PFS”) prepared in accordance with Canadian National Instrument 43-101 (“NI 43-101”) on the Zandkopsdrift rare earth element (“REE”) project in South Africa (“Zandkopsdrift”, the “Zandkopsdrift Project” or the “Project”). Zandkopsdrift is being developed by Frontier in partnership with Korea Resources Corporation, the wholly-owned mining and natural resource investment arm of the South Korean Government, which owns a 10% interest in the Project.

The results of the PFS indicate that the proposed development of Zandkopsdrift to produce a range of high purity, separated rare earths is both technically feasible and economically robust. In addition, the production of a saleable manganese sulphate by-product has been proven both technically and economically feasible and has been incorporated into the process flow sheet and economic analysis for the PFS.

PFS HIGHLIGHTS

  • The economic evaluation of the Project resulted in the following:
  • Internal rate of return of 30%, after tax and royalties
  • Net Present Value (“NPV”) of $2.98 billion, after taxes and royalties, at an 8% discount rate
  • NPV of $2.2 billion, after tax and royalties, at a 10% discount rate
  • NPV of $1.58 billion, after taxes and royalties at a 12% discount rate*
  • Production capacity of 8,000 tonnes per annum (“tpa”) of high purity, separated total rare earth oxides (“TREO”) for the first four years of operation (Phase 1), doubling to 16,000 tpa TREO from year five onwards (Phase 2)
  • Proven and Probable Reserves of 788,700 tonnes TREO, sufficient for a 45 year Life of Mine (“LoM”)
  • Production of 48,000 tpa of manganese sulphate during Phase 1, doubling to 96,000 tpa for Phase 2
  • Annual revenues of approx. $440m at Phase 1 capacity and approx. $880m at Phase 2 capacity
  • Average operating costs of $11.87/kg TREO (pre-contingency and net of by-product revenue credit) for the first 20 years of operations
  • Average annual operating margin of 69% for the first 20 years of operations
  • Total Phase 1 capital expenditure (pre-contingency) of $809m, comprising:
  • Zandkopsdrift Mine, excluding manganese sulphate plant – $523m
  • Manganese sulphate plant – $38m
  • Rare earths separation plant – $238m
  • Phase 2 capital expenditure (pre-contingency), which is planned to be financed from Phase 1 operating cash flow, of $645m
  •  Approximately 76% of Project revenues are derived from critical rare earth oxides and 75% from magnet related REOs**
