Processing infrastructure includes a 1,500 tpd milling and Merrill-Crowe facility plus a 3,000 tpd crushing, heap leach, and carbon circuit. Amancaya underground operations were temporarily ceased in late 2024, with production currently sourced primarily from the Heap Reprocessing Project and Inesperada open pit. 2026 exploration targets include Cerro Guanaquito, Dumbo Sur, and Sierra Inesperada.
