Erdene Resource Development has published a preliminary economic assessment for its wholly owned Zuun Mod molybdenum copper project in southwestern Mongolia, putting the build cost at 687 million dollars and the after tax net present value at 745 million dollars at an 8 percent discount rate. The proposed open pit would produce an average of 19.8 million pounds of molybdenum and 27.9 million pounds of copper a year over 34 years, with payback in the sixth production year. The assessment is preliminary: inferred resources account for about 74 percent of the proposed plant feed, and the study does not establish reserves.
Erdene outlines 687 million dollar Mongolia molybdenum build
Erdene Resource Development has outlined a 687 million dollar development plan for its Zuun Mod molybdenum copper project in southwestern Mongolia.
Why it matters: The study gives Erdene a potential second development centre alongside its Bayan Khundii gold mine, with drilling to upgrade the resource due to start in late October.
