SnapshotMining operations at the Noche Buena open pit were completed in May 2023 and the mine closure plan is proceeding as expected.

While pit operations have ceased, inventory recovery continues as long as it remains economically viable. The progressive closure plan focuses on restoring land for livestock and wildlife use, with a 20-year post-closure commitment to rehabilitation and maintenance. This includes the removal of most access roads, power corridors, and water infrastructure, while ensuring waste facilities and processing areas are safely decommissioned. Certain structures, such as leaching pads, may require extended care.
