La Granja copper deposit is located in Peru, in the Querocoto district of the northern region of Cajamarca. It is 90 kilometres northeast of Chiclayo, the capital of the Lambayeque region, between 2,000 and 2,800 metres in altitude.[1]
La Granja was discovered in the early 1980s. It was owned by Rio Tinto from 2006 to 2023, and the company completed extensive drilling to expand the resource. In August 2023, First Quantum Minerals acquired a 55% interest and now operates the project.[2]
On May 11, 2026, First Quantum filed a Technical Report for La Granja, highlighting its position as the second-largest greenfield copper resource in the world, with the potential to become a top-tier, multi-generational copper mine.[3]
La Granja is a large-scale copper porphyry-skarn-epithermal system. The 2026 43-101 Technical Report listed approximately 4.831 billion tonnes of Measured and Indicated Resources at 0.48% copper (“Cu”), comprising 23.0 million tonnes of contained copper, and approximately 5.206 billion tonnes of Inferred Resources at 0.40% Cu, comprising an additional 20.7 million tonnes of contained copper (0.16% Cu cut-off grade).[3] First Quantum is in the process of completing more economic studies to move the project towards a Mineral Reserve declaration, as none have yet been defined.[3]
First Quantum is still working towards the deposit's progression, including resource drilling, building support and trust within the surrounding communities, and advancing permitting and ESG studies to provide a base for an Environmental and Social Impact Assessment (“ESIA”), which is necessary for mine development.[4]
