Chapi

The Chapi Mine, owned by Minera Pampa de Cobre S.A.C. (indirectly owned by Quilla Resources Inc.), is located in the prolific Southern Peru porphyry copper belt across the Moquegua and Arequipa Departments, which host large scale operations including Southern Copper’s Toquepala, Anglo American’s Quellaveco Project, and Freeport-McMoRans’s majority owned Cerro Verde mine.

All of these deposits and districts, as well as others, comprise the Paleocene-Eocene Cu-Mo porphyry belt of Southern Peru, and contribute to making Peru the second ranked copper producer in the world.

The asset sits at an elevation of approximately 2,750 meters and has ready access approximately 50 kilometers south-southeast from the city of Arequipa. The mine, which was in operation from 2006-2012, reached maximum production levels of 8,500 tonnes per annum. The deposits at Chapi are composed of sandstone-hosted copper mineralized mantos, which are partially oxidized and secondarily enriched and are related to a series of porphyry intrusions.

The historic Chapi Mine is comprised of two principal open pits, underground workings, a crushing and agglomeration circuit, heap leach pads, a solvent extraction plant, an electrowinning copper cathode plant, and related infrastructure including mine camp, office facilities, water supply, and power. The restart and successful commissioning of the SX-EW plant in 2026 was achieved on time and budget, reflecting management’s strong track record as operators and work has begun on Phase 2 expansion as well as fast tracking investment in exploration and ongoing investment to optimise operations.

Nearby mines and deposits provide context for the project, but do not necessarily indicate similar size, styles or grade of mineralization within the project.
