Teck Resources Ltd. said Aug. 8 that the phase-two development of its Quebrada Blanca copper project in Chile received regulatory approval from the Tarapaca Region administration.
The Environmental Committee of Tarapaca voted to approve the project's environmental impact assessment, and the company can now move on to making a construction decision, which could come as early as the fourth quarter.
The expansion would include a 140,000-tonne-per-day concentrator, tailings storage facility, concentrate pipeline, water supply pipeline, desalination plant, concentrate filtration plant and port to produce copper and molybdenum concentrates.
The project would be low-cost, with an initially permitted mine life of 25 years using only a quarter of reserves and resources and significant potential for further growth, the company said. It would produce 300,000 tonnes of copper equivalent per year for the first five years.
