Bulyanhulu is a high-grade underground gold mine with by-product copper and silver production, owned and operated by Acacia Mining (previously known as African Barrick Gold). Mining has historically been form the Bulyanhulu deposit, complemented by production from the Upper East zone located approximately 2km from the main Bulyanhulu shaft. In addition to a 1.1Mt/a processing plant, a 2.4Mt/a carbon-in-leach (CIL) plant was installed to re-treat tailings from the flotation circuit as well as historic material from storage facilities. The plant was designed to produce gold dore and concentrate on-site, with a copper-gold-silver concentrate shipped to copper smelters in Asia. Following a concentrate export ban in 2017, underground mining activities were suspended as the mine transitioned to reduced / limited operations phase. Gold production is expected to be significantly lower at 30-35koz/a (mainly from tailings retreatment) until restrictions imposed by the export ban are lifted.
