Acerca de Las Bambas
Las Bambas is one of the most important mining projects undertaken in the country and is expected to become one of the largest global producers of copper.
Las Bambas has an Ore Reserve of 7.2 million tonnes of copper and a Mineral Resource of 12.6 million tonnes of copper and is expected to produce more than 2 million tonnes of copper in concentrate in its first five years.
Las Bambas ore will be mined via three open pits: Ferrobamba, Chalcobamba and Sulfobamba. Ferrobamba is located 10 kilometres east of the concentrator plant, while Chalcobamba and Sulfobamba are north and west of the concentrator, respectively.
Pre-stripping operations commenced in April 2014 and moved approximately 75 Mt of overburden prior to commencing ore processing, as forecast.
The concentrator has been designed to treat 140 ktpd (equivalent to 51.1 Mtpa) and has additional space within its footprint to increase grinding capacity. The mine produces copper concentrates containing gold and silver as by-products, and a separate molybdenum concentrate, and processing is carried out using conventional crushing, grinding and flotation techniques.
Las Bambas is expected to operate for more than 20 years due to its considerable exploration upside potential, with only 10% of the total land holding explored to date.
In August 2014, the Glencore Group sold all of its interest in Las Bambas to a joint venture owned by MMG Ltd., GUOXIN International Investment Corp. Ltd. and CITIC Metal Co. Ltd.
