How do development, production, grade, recovery, and commodity-price assumptions shape the mine plan?
Model profile
Gold Small-Scale Mining
An artisanal and small-scale gold mining enterprise or cooperative, set up for Ghana or for any country you choose: alluvial gravel washed through a mercury-free gravity plant, hard rock milled in an own small CIL plant or at a toll mill, ore sold to an ore buyer, or old tailings re-treated, with the gold sold to the licensed buyer at a payable share of the LBMA price. Tested the way a buyer and a lender would: the grade, the recovery, what the buyer deducts and when it settles, the royalty at today's gold price, the rains, and debt sized on the cash the mine can service.

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 grams per tonne and troy ounces, with a resource limit and an exploration stage
- Alluvial, hard-rock or tailings ore, with drilling and blasting only for hard rock
- Own gravity or CIL plant, toll milling, or ore sold on a grade-price grid
- Gold sold to the licensed buyer at a payable share of the LBMA price, less charges per ounce
- Provisional payment on the field assay and final settlement on the refinery assay, priced over a final pricing period
- Fineness and element deductions on the dore, moisture on the haul, and break-even haul distance on the scorecard
- A researched Ghana profile, GoldBod and the L.I. 2517 sliding royalty, and every other country selectable
- The licence type, term, area and ownership rules, and a check that processing is mercury-free
- Local-currency costs with pass-through, 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 all-in sustaining cost per ounce, break-even gold price, payability and head grade
- Rehabilitation per acre, a reclamation bond, and a lender scorecard
- A gold price deck, named scenarios, an NPV tornado and a Monte Carlo
