The scramble to extract critical energy transition minerals creates risk of widespread negative human rights impacts. A just transition in the extraction of critical minerals must involve deep examination of the mine-community interface to gain a better understanding of the drivers of successful engagement between mining companies and communities. Drawing on fieldwork in South America’s lithium triangle, this paper finds that the nature of the corporate-community relationship is increasingly key to enabling a just transition whereby communities participate in the benefits of extraction with negative impacts mitigated. It establishes that key success factors are related to empowerment of Indigenous communities and have the potential to maximise positive outcomes for communities in the context of lithium extraction. Governments and companies must embed a more bottom-up process with an end goal of communities themselves defining the parameters of what a just transition means in the critical minerals context.
