Constancia is one of the lowest cost open-pit sulphide copper mines in South America

Hudbay arrived in Peru with the acquisition of the Constancia copper project in 2011. Constancia is Hudbay’s 100% owned copper operation located in the province of Chumbivilcas in southern Peru and consists of the Constancia and Pampacancha deposits. We completed construction of Constancia in 2014, and the mine went from first production to full production in just five months. The Constancia operations also include the nearby Pampacancha satellite pit, a high grade copper-gold deposit where mining activities began in 2021 which will be completed in late 2025.

The company acquired a series of properties near Constancia, adding a large, contiguous block of exploration prospects within trucking distance of the Constancia processing facility, including the past producing Caballito property and the highly prospective Maria Reyna property. The company commenced early exploration activities at Maria Reyna and Caballito after completing a surface rights exploration agreement with the community of Uchucarcco in August 2022. As part of the drill permitting process, environmental impact assessment (EIA) applications were submitted for the Maria Reyna property in November 2023 and for the Caballito property in April 2024.

Strengthening safety, efficiency and production at Constancia

Environment

As part of our efforts to manage air quality, Constancia uses a dust suppressor on a 10-kilometre stretch of road. Hudbay was the first mining company in southern Peru to use the dust suppressor and, following its success, many other mining companies in the area have also begun to use it.

Community & People

Open, honest and continuous community engagement is critical to exploring and developing new mines. This is what we did and continue to do in Peru. We have also made every effort to learn about the language and values of the Peruvian people and to integrate the operation into their culture. In doing so, we have built strong, positive relationships. Since 2012, we have reached more than 90 agreements with communities near Constancia. These agreements include commitments related to local employment and procurement and investments in health, education and infrastructure initiatives.
