Figure 2 – Stakeholder Positioning Map illustrating the relationship between power/influence and interest for the identified stakeholders Ultimately, a successful investment model leverages synergies between these stakeholders. The financial evaluation must quantify not only revenue from recovered minerals but also the critical value of eliminating the catastrophic failure risk associated with legacy facilities constructed under high geotechnical limitations. By removing these physical hazards, the project safeguards not only the asset owner but the reputation of the entire mining industry. This dual value stream, economic profit and verified safety, aligns the interests of investors, regulators, and communities, transforming the project into a robust investment for a circular mining economy. 4. DISCUSSION: AVENUES FOR FUTURE RESEARCH AND SOURCES OF UNCERTAINTY 4.1 Practical Insights: Key Lessons Learned The application of the viability framework described in Section 3 has yielded several critical insights from direct consulting experience. These key lessons, which are essential for de-risking projects in practice, are summarized in Table 1. Table 1 – Key Lessons Learned in the Design of Tailings Reprocessing Projects (Consulting Experience) Common Challenge Mitigation Strategy Resource Characterization Underestimation of spatial and mineralogical variability. A robust 3D block model is essential. Invest in a drilling campaign with a denser grid than standard for a TSF, supplemented by geophysical surveys to interpolate between points.
