en.Wedoany.com Reported - Compañía de Minas Buenaventura S.A.A. (NYSE: BVN) plans to invest approximately $70 million in its Orcopampa operation in the Arequipa region. The investment will be used to introduce filter press technology in the tailings disposal process to extend the tailings dam's lifespan and optimize process efficiency.

Founded in 1953 and headquartered in Lima, Peru, Buenaventura is one of the largest publicly traded precious metals producers in Latin America. The company operates eight production units in Peru, including the Orcopampa, Uchucchacua, and Julcani mines. The Orcopampa mine, an underground gold and silver mine, began production in 1967 and is currently 100% owned and operated by the company.

The Orcopampa project is located in the districts of Orcopampa, Chilcaymarca, and Chachas in the Castilla province, as well as the Cayarani district in the Condesuyos province. The mine's processing plant currently treats approximately 18,500 metric tons of ore per month, producing gold and silver concentrates. The plant is equipped with thickening and detoxification facilities for tailings treatment, with the thickener discharge containing nearly 50% solids.

The currently operational R4A tailings dam has a remaining service life of approximately two years. To sustain continuous operations at Orcopampa, Buenaventura is seeking to extend the lifespan of the R4 tailings dam and has proposed adopting filter press technology for tailings disposal. According to industry media reports, the filter press plant is designed with a processing capacity of 30,000 tons per month and is expected to extend mine operations until 2032. Further details on the implementation of this investment plan are yet to be disclosed.
