170 dependent upon the anticipated future use and critically must be deemed acceptable by the key actors involved in the transition. This is further complicated by what has been noted as an unwillingness from industry and government representatives or a lack of process for governments and stakeholders to accept residual risk, particularly in well-developed mining jurisdictions (IGF, 2023). Repurposing of mined land and infrastructure has increasingly been seen as an important closure opportunity, offering the possibility of generating post-mining value and potentially attract investment using new and innovative technologies and solutions (Perlatti and Gagen, 2024). However, this can make the calculation and transfer of the residual risk, as well as the required management plan and funding mechanism much more complex. Repurposing also raises temporal complexity as the timing of residual risk assessment and agreement is critical to building investor confidence and enabling transitions to economic postmine uses (Maybee et al, 2024). 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 enviroMETS3, 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. 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. 3 a Queensland focussed independent, not-for-profit, industry-led organization focused on transforming miningimpacted land into valuable, sustainable assets
