Critica Ltd says it has cut sulphuric acid consumption by about 30% at its Jupiter rare earths project in Western Australia. The company presents this change as a process improvement that reduces a key operating input for the project. Multiple outlets report that the reduction is intended to lower operating costs and improve overall project economics. The update is also described as strengthening the case for the project ahead of an upcoming scoping study. While the reports focus on the magnitude of the sulphuric acid savings and the expected benefits, they do not provide additional technical detail in the material provided. The articles broadly frame the development as a cost-related milestone that could influence how the scoping study assesses feasibility and future project design. Overall, the coverage is consistent in attributing the cost reduction to improved performance at the Jupiter site and in linking the news to preparation work for the next stage of project evaluation.
