South America: Chinchillas

Chinchillas is a high-altitude silver, lead, and zinc deposit in northern Argentina. SRK worked on this project from 2015 to 2019 encompassing different levels of studies including preliminary economic assessments, pre-feasibility and feasibility. SRK provided mine operating cost estimates, detailed monthly plans, dilution models, waste dump designs, stockpile designs and access roads, site layout, cut-off grade, and pit optimisation. In summary, SRK engaged in detailed mine design and production planning suitable for construction and development that led to a positive construction decision for the open pit mine by 2018.
