1090 Managing risk in post mine land and asset use decisions requires an assessment of the value associated with different options. Our research, in partnership with enviroMETS21, has developed Multicriteria Analysis Tools (MCAT) that provide a structured way of comparing alternative post-mining land use (PMLU) options for a site (enviroMETS and CRC TiME, 2026). This framework is meant to support decision-making for different stakeholder groups, and as such, will be developed in a way that can be used by these groups to understand the position being taken by others, thereby facilitating transparent communication. The tool is potentially applicable for planning and decision support at all stages of the mining life cycle from early-stage mine planning, through to mine closure scenario modelling and decisionmaking for legacy sites. Importantly, the qualitative and quantitative evaluation approaches we have developed provide a more complete way for diverse stakeholders to view the holistic value of alternative options while also providing a clear mechanism for evaluating economic return. 7. CONCLUSIONS Our paper has drawn together research undertaken through the Cooperative Research Centre on Transformations in Mining Economies (CRC TiME), a partnership of over 80 mining and supply chain companies, research institutions, government bodies, regional, Indigenous and natural resources organizations to help address four inter-related challenges: (1) creating a enabling regulatory and policy environment that removes unnecessary barriers to repurposing; (2) enabling mining core business to facilitate appropriate land stewardship beyond the completion of mining; (3) ensuring that the voices of local communities and Indigenous people are heard, involved in decision making and derive value from repurposing (4) developing methodologies for identifying and assessing viable options for post-mining land use, repurposing and ongoing governance. Global demand for mineral resources continues to grow, with forecasts suggesting pressure both on expanding mining in existing operations and the development of new mines. At the same time, many mines are maturing, reaching a point where the resource has been exploited and it is uneconomic for mining to continue while asset acquisitions often include legacy assets. Increasing expectations are being placed on mines to leave a positive legacy, but growing closure related OpEx costs, asset retirement obligations, and total closure liability estimates are also placing increasing pressure on the sector. Creating pathways enabling closure and relinquishment of assets and transition of mining assets is a growing priority. At the same time, governments, communities and other sectors are increasingly recognizing the value of repurposing or reusing mining related infrastructure, waste and land for future use. Addressing this nexus by creating an environment that optimizes value generation through mine closure and post mine transitions, while managing residual risk, is a key priority for stakeholders for both mining and post-mine stakeholders. Through innovation across these four areas, the sector can de-risk mine closure, increase confidence in positive legacy development and open new value paths for governments and communities.
