  • Build & operate GoldConstruction, operating & closure costs, production schedules and taxes determine each mine’s cash flow.
  • Risk lens GoldRisk inputs reduce each mine’s NPV to reflect uncertainty, lowering its contribution to company NAV and value per share.
  • Sensitivity Analysis GoldCompare Bear, Base & Bull cases and test how changes in metal price, costs, capex and discount rate move value. Then see how funding the build with new shares dilutes NAV per share.

Market snapshot

Start with what the market knows. Enter the share price, share counts, debt, cash and a production line for each metal.

  • Market cap and enterprise value
  • Model value per share from a cash-flow multiple you choose
  • FCF proxy per share and EV / cash flow
Silver and Gold

Resource inventory

Assess deposit scale, quality, ownership and geological confidence for each mine, one line per commodity and category.

  • Proven and probable, measured and indicated, inferred
  • Ore tonnes, grade, recovery and ownership
  • Choose reserves only, include measured and indicated, or include inferred, netted against reserves
Gold

Build & operate

Enter the costs and operating assumptions that determine each mine’s cash flow, from construction and production to closure.

  • One asset per mine: ownership, start year, mine life and production schedule
  • Initial and sustaining capex, closure cost
  • Royalty, tax rate and discount rate for each mine’s finite NPV
Gold

Risk lens

Assess technical, permitting, funding and jurisdiction risks. These inputs reduce each mine’s NPV, which flows through to company NAV and value per share.

  • Metallurgy, permitting and execution risk
  • Funding, jurisdiction and social / ESG risk
  • One combined risk adjustment you can trace
Gold

Sensitivity Analysis

Stress-test the case before relying on a single valuation outcome.

  • Editable Bear, Base and Bull cases
  • Sensitivity to price, cost, production, capex and discount rate
  • Sum of parts with cash, debt and corporate G&A, to NAV per diluted share

Everything around the calculator.

The workspace is more than a form. It keeps your companies, your comparisons and your market context in one place.

Independent metrics

Twelve estimates, each with its own prerequisites. A missing input makes only that metric unavailable; the rest still calculate.

Saved companies

Sync valuation snapshots to your account and open them on any device. Silver saves up to 15 companies.

Side-by-side comparison

Compare companies on the same screen and download comparison snapshots. Included with Gold membership.

Mining stocks & metal prices

View mining stock quotes and charts alongside gold, silver and copper reference prices. Metal prices are display references and never change your model inputs.
