Methodology

Version v0.1

Resource Quality: 86 (weight 1.2) — Grade, continuity and metallurgical complexity of the resource.
Project Scale: 80 (weight 1) — Annual output potential relative to the global market for its primary mineral.
Development Stage: 77 (weight 0.9) — How far the asset has advanced toward or through production.
Jurisdiction: 82 (weight 1.1) — Political stability, permitting predictability and rule of law.
Infrastructure: 72 (weight 0.9) — Access to power, water, transport and processing capacity.
Economics: 84 (weight 1.2) — Cost position and margin resilience through the price cycle.
Strategic Importance: 83 (weight 1) — Relevance to national critical mineral strategies and allied supply chains.
Supply-Chain Value: 84 (weight 1) — Whether the asset relieves a genuine downstream bottleneck.
Sustainability: 72 (weight 0.9) — Carbon intensity, water use, tailings approach and community standing.
Execution Risk: 78 (weight 1) — Technical, financing and schedule risk to reaching nameplate output. Higher is lower risk.

Materials
