China's Minerals and Metals Group (MMG) is planning to invest $100m for expansion of the Golden Grove copper-zinc mine east of Geraldton, Australia.
With this expansion, the Golden Grove mine will produce between 59,000t and 67,000t of copper metal, reports Mining Australia.
In 2009, Oxiana, the previous owner of Golden Grove mine discussed the development to extend mine life and keep its processing plant running, but the plan was discarded due to financial crisis.
Last year, MMG looked at the pit plans again, and is planning to expand the mine as part of development.
The firm has released an upgrade resource statement from the original pit plan, which shows that it could mine 3.1 million tons of copper oxide at 2.2%, for 672,000t of contained metal, up from 2.5 million tons of copper oxides grading 2.5% and 900,000t of coppers sulphides at 2%.
