Methodology
Transparent geographic exposure plus an evidence-backed Grey Rabbit mining jurisdiction score (100 = lowest risk). Separate from valuation — not a black-box geopolitical index.
Jurisdiction risk describes where a miner's mines and projects are located and the political, regulatory, fiscal, security, and social risks surrounding those assets. It answers: where are the assets, how much exposure does the company have, what are the risks, why is the classification what it is, and how current is the evidence.
Two miners with similar costs and reserves can face very different sovereign, security, and fiscal environments. Investors often need geographic context before deciding how much jurisdiction risk should matter to their own valuation judgment.
Structural jurisdiction riskis the reviewed categorical classification of a country's operating environment. Current event pressure (Normal / Watch / Elevated / Critical) updates from active monitored events and is designed to be responsive.
Current events do not automatically change Grey Rabbit's structural jurisdiction classification. Material structural changes create review proposals and require admin approval (or an explicitly permitted high-confidence rule path). History is append-only.
Events may arrive from an inbox drop (data/miner-jurisdiction/inbox/), optional RSS feeds (feeds.json), and a curated bridge of Sprint 1.0 events. Source tiers: 1 authoritative, 2 high-quality reporting, 3 specialist, 4 unverified. Tier 4 cannot independently trigger a published structural risk change.
Corroboration, materiality, and exposure-aware assessment are deterministic. Public pages read cached monitoring snapshots only — no news API calls during render. Monitor cadence: every 6 hours via /api/cron/jurisdiction-event-monitor.
Jurisdiction risk is presented separately from Grey Rabbit's Miner Valuation methodology. Sprint 1.0 does not automatically discount a company's valuation because of its jurisdiction classification. There is no jurisdiction haircut, risk premium, or multiple adjustment inside computeMinerValuation.
Grey Rabbit publishes a mining-investment jurisdiction score from 0–100 where 100 = lowest risk / best mining jurisdiction and 0 = highest risk. The score answers how favorable and secure a jurisdiction is for long-term economic ownership and operation of a mining asset — not generic political risk and not a Fraser Institute ranking.
Eight fixed pillars: rule of law (20%), mining policy & tenure (20%), fiscal / royalty stability (15%), permitting (15%), resource nationalism (10%), security (10%), infrastructure (5%), and social / community disruption (5%). Bands: 85–100 very low, 70–84 low, 55–69 moderate, 40–54 high, 0–39 very high. Confidence (High / Medium / Low) and optional critical-risk flags are shown alongside the score.
Country base scores cover Mining 50 operating countries. Subnational adjustments apply only where evidence supports differentiation (for example Nevada vs California). Fraser Institute survey data is treated as perception only and is not redistributed as raw scores.
The Lab still shows categorical structural labels (Low, Moderate, Elevated, High, Severe, or Unknown) for map coloring and event monitoring. Unknown never becomes Moderate by default. Numeric scores are shown as Score / 100 with an explicit risk band and confidence.
Each country record exposes categorical dimensions such as political stability, regulatory / contract security, fiscal / royalty risk, resource nationalism, security / conflict, sanctions / capital controls, social disruption, and infrastructure / energy risk — plus the eight numeric pillars above when a Grey Rabbit score is populated.
Assets store ownership percent separately. Joint ventures are not assumed to be 100% owned. Attributable exposure uses reported ounces × ownership when both are verified; otherwise the field remains unavailable.
Production exposure (flow) and reserve exposure (stock) are calculated separately and never blended. Percentages use the represented attributable denominator in the dataset and disclose incomplete coverage. Company-weighted numeric jurisdiction scores are published only when those weights are defensible; otherwise the Lab states that a weighted score is awaiting exposure data.
Evidence Quality (High / Moderate / Limited) on categorical records refers to coverage strength of that curated profile. Numeric scores carry a separate Confidence label (High / Medium / Low). Neither is a Miner Score.
Mining 50 material assets are mapped for geographic exposure; many assets intentionally lack coordinates when authoritative pins are unavailable. Jurisdiction scores use country and subnational fields, not invented map pins. Classifications and scores carry as-of / last-reviewed dates. Production figures in the asset dataset are rounded company-disclosed starting points and may not equal 100% of consolidated reporting.
Jurisdiction Risk is analytical context, not a recommendation. See the site disclaimer.
