Crush and grind near mine with ore slurry line to a coastal concentrator, producing separate copper and molybdenum sulphide concentrates.
Detailed investigation of local rivers for the generation of clean, low cost hydroelectric power supply.
Implementation of world class environmental standards and community relations initiatives to ensure a successful project for all stakeholders.
