Project Details
Santa Cruz province
Cerro Negro is a system of low sulphidation epithermal (gold and silver) mineral deposits hosted in quartz veins. Cerro Negro has five known mineralized zones: Eureka, Mariana Central, Mariana Norte, Bajo Negro, Silica Cap and San Marcos.
Gold - Silver
Production
$1,650,000,000.00
Cerro Negro mine operations are low sulfidation, epitermal gold/Silver vein deposits. Cerro Negro’s available underground mining fleet consists of 10 underground loaders, 12 underground haul trucks and 7 surface haul trucks, each with 30 to 40-tonne payloads and additional auxiliary equipment as required. Cerro Negro is the first and only mine in Argentina with teleoperation; new technology in the mining operation that allows to reinforce the safety of operators by reducing their exposure, increasing the useful life of the equipment and optimizing the productivity of the operation.
The processing plant facilities consist of a crushing plant, a grinding circuit (4,000 tpd), agitated leaching, counter-current decantation, solution clarification, Merriil Crowe zinc precipitation and smelting to produce gold/Silver doré bars that are shipped to a refinery for further processing.
280,000 oz of gold (2023)
10 Years
- By the end of 2022
- 3 Moz of gold and 19.5 Moz silver (proven and probable resources);
- Resources (measured and indicated & inferred): 1.8 Moz of gold and 9.7 Moz Silver

Additional Comments
Newmont Cerro Negro has three high-grade underground operating mines – Eureka, Mariana Central and Mariana Norte – and two underground deposits – Emilia, which reached commercial production in 2022, and San Marcos, which is currently being developed. Cerro Negro also has five other deposits in late-stage evaluation for development to expand the existing operations in the Marianas Complex and establish operations in the Eastern District. The extensive Cerro Negro complex has several other deposits and exploration targets, including an open pit mine known as Vein Zone and one cyanide leach processing facility with Merril Crowe recovery yielding gold recoveries of 90 to 97 percent. The project is expected to improve annual production 300 Koz beginning in 2024 / Extends mine life of existing operations beyond 2030 / The first expansion includes the development of Marianas and Eastern districts unlocking value through shared resources. Highly prospective and underexplored gold district: among the top land packages in Newmont’s portfolio; doubled size since Goldcorp acquisition / Deposits remain open along strike and at depth / Provides platform for further exploration and growth through future expansions
