How do development, production, grade, recovery, and commodity-price assumptions shape the mine plan?
Model profile
Bauxite Small-Scale Mining
A small-scale bauxite miner or cooperative, set up for Guinea or for any country you choose: export-grade bauxite screened and trucked to a river terminal and sold to a consolidator, washed to a premium grade, exported on the miner's own account, sold to a cement plant, or mined by a contractor for a cooperative. Tested the way a buyer and a lender would: the alumina grade and reactive silica, the bauxite index and what the buyer pays after its barging charge, the haul, the extraction tax on aluminium, the rains, and debt sized on the cash the mine can service.
Decision scope
Questions this model helps you examine
What capital, operating cost, closure provision, and financing structure are required?
How do price, grade, recovery, cost, and schedule downside cases affect investment returns?
Model capabilities
What this model includes
The profile below is generated from the same catalogue and workspace definitions used by the application.
- A 10-year mine plan in per cent Al2O3, with a resource limit and an exploration stage
- Screening or washing to a product of higher grade: mass yield, alumina recovery and moisture
- The product priced per dry tonne on the bauxite index, adjusted for alumina, less the buyer's charge and reactive silica penalties
- Haulage by route segment per wet tonne-kilometre, and the break-even haul distance
- A researched Guinea profile with the extraction tax on LME aluminium, and every other country selectable
- The local development contribution, the export tax and the State's free carried interest
- Local-currency costs, and a local-currency or dollar loan
- Debt sized and sculpted on cash available for debt service, with a reserve, a lease and a buyer prepayment
- Cash cost and realised price per dry tonne, break-even bauxite price, payability and haul
- A bauxite price deck, named scenarios, an NPV tornado and a Monte Carlo
