## Company history

Buenaventura was founded in Peru on April 27, 1953, when it acquired Julcani, its first operating mine. Alberto Benavides de la Quintana was the company’s founding president. The company’s early growth included starting operations at Recuperada in 1956 and Orcopampa in the 1960s; Uchucchacua’s industrial plant was installed in 1975. [31](https://buenaventura.com/en/nuestra-historia/)[11](https://app.finbar.com/go?id=P152086898)[32](https://app.finbar.com/go?id=P152086826)[8](https://app.finbar.com/go?id=P152086842)

Buenaventura expanded its interests with a participation in El Brocal in 1979 and operations at Ishihuinca in 1980. In the 1990s it developed partnerships involving Yanacocha and Cerro Verde, and listed on the New York Stock Exchange in 1996. Later milestones included the start of La Zanja in 2010 and Tantahuatay in 2011, the first doré bar at Tambomayo in 2016, Yumpag’s start in 2024, and the beginning of San Gabriel operations in January 2026.
