Flagship initiative
The Mining Fiscal Regime Simulator
A decision-support platform for evaluating mining fiscal regimes under market, project, and policy uncertainty. MiFRS links mine-level project economics with fiscal terms to help users understand how royalties, taxes, state participation, incentives, and other mechanisms affect government revenue, investor returns, and the distribution of project value over time.
Built for uncertainty, not static assumptions
Mining fiscal decisions are often made using static assumptions about commodity prices, production, costs, reserves, financing, and project schedules. In practice, however, these variables often change substantially from expectations. MiFRS helps users test a range of plausible futures — such as price volatility, cost overruns, delays, grade variation, and policy changes — before those uncertainties become budget shortfalls, difficult renegotiations, or supply security concerns.
The platform is designed to move beyond static and specialist-dependent spreadsheets. It provides transparent assumptions, comparable outputs, and scenario-based workflows that can be used across projects, commodities, and jurisdictions.
Outputs
Indicators under multiple fiscal and market conditions
Users can assess a consistent set of indicators across scenarios, projects, commodities, and jurisdictions. Key indicators include:
Capabilities
Analyze implications for government and investor planning across scenarios, with features like rapid-scenario analysis, random price simulations, fund formation and subnational distributions, sensitivity analyses, and more.
Applications
Where MiFRS supports decisions
ARPL works with partners to calibrate models to priority assets and policy questions, develop scenarios, and establish repeatable analytical workflows that remain useful after the initial engagement.
