The copperCopper industry, driven by the energy transitionEnergy transition scenario, is projected to grow from 1.2 Mt in 2020 to 3.5 Mt in 2030 and 5.4 Mt in 2040. This growth requires increased production by expanding existing operationsOperation or new miningMining projects. Given these market demandsDemand, this study focuses on greenfield projects and their value propositions—specifically, investmentInvestment amounts, timelines, and project scope. The methodological framework employed assesses the fulfillment of the value proposition in terms of investmentInvestment amount, production start dates, and scope for the global portfolio of copper mining projectsCopper mining projects from 2015 to 2022. The approach consists of five steps: data collection, portfolio characterization, project selection, descriptive statistical analysisAnalysis, and clustering using the K-means algorithm. By clustering, it is possible to evaluate the level of similarity between projects and identify key factors influencing the fulfillment of their value propositions. This research enhances the understanding of key factors affecting the value proposition of miningMining projects, emphasizing the critical role of socio-environmental variables. These factors require further exploration through the compilation of regional best practicesBest practice. Finally, the study underscores the importance of robust strategic analysisAnalysis during the pre-investmentInvestment stages, particularly in business case evaluationsEvaluation, where the identified factors can guide discussions and improve decision-making processes. It will also highlight critical factors affecting the fulfillment of their value propositions.
