2524 ministries, play a central role in consolidating datasets, validating assumptions, and ensuring methodological consistency. Their mandate for neutral, evidence-based analysis strengthens credibility and continuity across political cycles. Midstream considerations show why integration is necessary. Processing and refining facilities are capital-intensive, often requiring long lead times and stable policy environments. Utilization rates determine economic viability; underused facilities quickly become stranded assets. Enabling conditions, such as a reliable energy supply, water availability, transport infrastructure, skilled workforce, and regulatory predictability, are decisive. Decisions to develop or repurpose midstream capacity, therefore, cannot rely solely on mineral endowment. They require alignment among resource maturity, industrial capability, and sustainability constraints. By linking nexus criticality with midstream readiness, the integrated framework supports disciplined evaluation of these interdependencies, reducing the risk of misaligned investments and reinforcing resilience across the value chain. 8. METHODOLOGICAL LIMITATIONS, SENSITIVITY CONSIDERATIONS, AND RESEARCH AGENDA The proposed workflow is designed as a screening-level instrument. It structures dialogue and improves transparency, but it does not replace detailed feasibility studies, financial modelling, or environmental impact assessments. Results should therefore be interpreted as indicative signals of systemic exposure, supply risks, and midstream readiness rather than definitive conclusions. Certain components rely on structured expert judgement, particularly where standardized data are incomplete or unavailable. Although scoring scales and documentation protocols are designed to increase consistency, expert inputs inevitably introduce subjectivity. Transparent recording of assumptions, peer review, and iterative refinement are necessary safeguards. Outcomes are also sensitive to weighting choices and scoring thresholds. Different policy priorities, such as security of supply, industrial upgrading, and environmental performance, may justify alternative weighting schemes. Sensitivity analysis is therefore essential to test the robustness of results and avoid over-interpretation of marginal score differences. Further validation requires pilot applications across diverse national contexts, followed by retrospective testing. Comparing screening outputs with actual project performance and policy outcomes will help refine indicators, adjust normalization approaches, and improve predictive relevance. Finally, integration with complementary analytical methods, such as life-cycle assessment, macroeconomic modelling, or strategic environmental assessment, can strengthen decision-support capacity. However, the framework is not intended to replace these tools. Its contribution lies in providing a structured bridge between project-level information and system-level governance within a manageable, operational scope. 9. ADVANCING INTEGRATED CRITICAL MINERAL GOVERNANCE THROUGH OPERATIONAL TOOLS Critical mineral governance requires coherence across project maturity, industrial capability, sustainability objectives, and system resilience. Fragmented approaches, such as separating geological assessment, industrial planning, and nexus policy, generate misaligned incentives and increase vulnerability across supply chains. An integrated governance architecture is therefore necessary to align resource development with long-term public value. This paper presents an operational approach that combines UNFC and UNRMS within a structured, sequential workflow. UNFC provides standardized project-level information on viability, feasibility, and confidence, reducing ambiguity around supply maturity and timeto-market. UNRMS frames how that information should be interpreted within broader sustainability, circularity, resilience, and equity objectives. Together, they translate technical resource data into policyrelevant insight.
