Methodology
Earthern Project Score 71
Version v0.1
- Resource Quality
- 80 (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
- 72 (weight 0.9) — How far the asset has advanced toward or through production.
- Jurisdiction
- 69 (weight 1.1) — Political stability, permitting predictability and rule of law.
- Infrastructure
- 65 (weight 0.9) — Access to power, water, transport and processing capacity.
- Economics
- 75 (weight 1.2) — Cost position and margin resilience through the price cycle.
- Strategic Importance
