The business

Mines narrow-reef or bulk platinum-group-metal ore, producing concentrate sold to smelters and refiners under purchase-of-concentrate agreements at a share of the basket price, or smelted and refined in-house into platinum, palladium, rhodium and by-product nickel and copper.

What it covers

25 parts, each one tested.

Every part is a tested building block with its own checks: yours is put together from the ones your business needs.

  • CPI forecastConsensus curve with long-run anchor
  • Exchange rate (US dollar)Exchange rate by financial year
  • Corporate costsFixed cost base indexed to CPI
  • Working capitalFull working capital
  • Income taxCorporate rate with tax losses
  • DebtAmortising term loan
  • Equity raisingDistribution reinvestment plan
  • Dividends and distributionsPayout of net profit
  • Discounted cash flow valuationDCF on free cash flow to the firm
  • Net asset valueBook net asset value
  • Group unit costs (single-product portfolios)C1, C2 and C3 cost per poundGroup unit costs, realised prices and margins that investors use to compare miners. Only meaningful when every mine sells the same product.
  • Exploration expenditureMetres drilled × cost per metreExploration and evaluation spend, how much is capitalised or expensed, and write-offs.
  • Key-metric summaryLast-twelve-month and run-rate metrics
  • Discount rate (WACC)CAPM at target gearing
  • Stockpiles and metal inventoriesOre stockpile at average costOre stockpiles, metal in circuit and on leach pads, and finished product held at cost; the movement adjusts cost of sales.
  • Emissions and carbon costsEmissions from activity × emission factors, at a carbon priceScope 1 emissions from diesel, fugitive methane, processing and on-site power, and the cost of carbon pricing, declining safeguard baselines or offsets.
  • Mine registerMine register with resource conversionThe facts every other part of the model builds on — mineable inventory (reserves plus any converted resources), carrying value and mine life.
  • Development and first productionInitial capex to first production, then ramp-upPre-production construction capex, first production date and ramp-up to nameplate for new mines and expansions. Development capex feeds the asset base (and so PP&E and investing cash flow).
  • Mining and processingMill throughput × grade × recovery (gold)The physical chain from ore and waste mined, through plant throughput, head grade and recovery, to payable product (in units of the mine's own product: ounces, tonnes, dry metric tonnes, pounds) and the reserves remaining.
  • Sales and realised pricesPartly hedged gold sales (hedge book at a fixed price)Product sold × realised price, including hedging, offtake terms, quality adjustments and smelter charges. Units sold and prices are per unit of the mine's own product; the market price (spot, or FOB for bulk commodities) is the royalty value basis.
  • RoyaltiesHybrid royalty (greater of ad valorem and profit-based)Government royalties, third-party royalties and community payments on each mine's production.
  • Site operating costsUnit rates (mining $/t, processing $/t, fixed site G&A)Mining, processing, site administration and (for bulk commodities) rail, port and shipping costs.
  • Mine assets and depreciationUnits-of-production depreciation on ore reservesSustaining and growth capex (including capitalised stripping and underground development) and depreciation of mine properties and plant.
  • Rehabilitation and closureClosure cost built up over the ore reservesThe rehabilitation and closure provision — build-up or unwinding, progressive rehabilitation spend and final closure. Build-up is an operating charge (direct costs); the unwinding of discount is a non-cash finance cost.
  • All-in sustaining costAll-in sustaining cost net of by-product creditsEach mine's all-in sustaining cost on the industry-standard definition, for unit-cost reporting.
