How do development, production, grade, recovery, and commodity-price assumptions shape the mine plan?
Model profile
Manganese Small-Scale Mining
A small-scale manganese miner or cooperative, set up for Zambia or for any country you choose: hand-sorted lump sold at the mine to an exporting trader, selective mining of the high-grade lenses, the miner's own export by road to Dar es Salaam, delivery to a ferroalloy smelter, or a cooperative licence worked by a contract miner. Tested the way a buyer and a lender would: the manganese grade and its silica and phosphorus, the CIF China index per unit and what the buyer pays after freight to China, the haul, the royalty on the index value, the rains, and debt sized on the cash the mine can service.
Decision scope
Questions this model helps you examine

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 Mn, with a resource limit and an exploration stage
- Hand cobbing and screening to lump of higher grade: mass yield, manganese recovery and moisture
- The product priced per dry metric tonne unit on the CIF China index, adjusted for grade, less the buyer's freight to China and silica, iron and phosphorus penalties
- Haulage by route segment per wet tonne-kilometre, and the break-even haul distance
- A researched Zambia profile with the mineral royalty on the norm value and the small miners' turnover tax, and every other country selectable
- 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 manganese price, payability and haul
- A manganese price deck, named scenarios, an NPV tornado and a Monte Carlo
