The Miner’s Dossier: ARU (Arafura Rare Earths)

2026-05-07 // Build

A demonstration of the 'Structural Realist' approach to equity research. We move beyond narrative hype to present a deterministic, citation-backed dossier of the Nolans Neodymium-Praseodymium (NdPr) project.

Beyond the Investor Presentation

Most retail investors rely on glossed-over investor presentations. For the institutional practitioner, value is found in the “Hard Gates” of a project’s Definitive Feasibility Study (DFS).

This dossier is generated by our Rare Earth Shortlist Pipeline, which ignores marketing adjectives and focuses strictly on primary-source extraction from ASX announcements and regulator filings.

Live Grounding Trace

The terminal below illustrates the pipeline’s “Grounding Mode.” As the LLM extracts economics, it must provide a verbatim snippet from the source document. If no snippet is found, the value remains null.

Watch the grounding engine verify the Project NPV and Capex against the 2023 DFS Update.

Institutional Project Metrics

[AUDIT-READY DATA] Project Economics: Nolans

The following metrics are normalized to a common 8% discount rate for cross-commodity comparison. Any value marked with a ✅ has a confirmed audit trail to an ASX filing.

Metric	Extracted Value	Source Filing	Grounding
NPV (8% After Tax)	A$2.32 Billion	ASX: 11-Nov-23	✅ VERIFIED
Initial Capex	A$1.59 Billion	ASX: 11-Nov-23	✅ VERIFIED
IRR	19.3%	ASX: 11-Nov-23	✅ VERIFIED
Annual NdPr Oxide	4,440 tonnes	ASX: 11-Nov-23	✅ VERIFIED

Sensitivity & Risks

A structural realist must account for the “Tail Risk” of execution. In the Nolans project, the primary sensitivities are Capex Inflation and Reagent Costs.

Reagent Sensitivity: The project relies heavily on sulfuric and phosphoric acid. A 10% spike in reagent costs reduces the Project IRR by approximately 1.4%.
Financing Gate: The project requires significant debt facilities. Current status: Debt-led financing path (ECA supported).

Conclusion

The “Miner’s Dossier” replaces the analyst’s bias with a deterministic data extraction layer. By hosting this on the PTR Labs platform, we provide a transparent, reproducible benchmark for evaluating critical mineral projects.
