Deposit Type

  • Epithermal


Summary:

The Mulatos mineral deposits are large epithermal, high-sulfidation, disseminated, gold deposits hosted within a mid-Tertiary dacitic dome complex. Gold mineralization is closely associated with silicic alteration within extensive areas of argillic and advanced argillic alteration. The Mulatos deposit proper is composed of the contiguous Estrella, El Salto, Mina Vieja, and Puerto del Aire Mineral Resource areas. The Escondida deposit is the faulted extension of the Mina Vieja and El Salto subdeposits and is believed to be continuous to the northeast with the Gap, El Victor and San Carlos mineralized areas. Although zones are often bounded by post-mineral faults, together they form a trend of 2.7 km of gold mineralization starting at the north end of the Estrella pit to the San Carlos deposit.

Within the larger Mulatos Group of Concessions, and generally within 20 km from the Mulatos deposit, geologically similar high sulfidation gold deposits, occurrences, or prospects are known. The principal ones, some of which are in the process of being evaluated and/or drill-tested, are: El Carricito, El Halcon, Las Carboneras and El Jaspe.

Gold deposits of the Mulatos district are considered to be high sulphidation-state epithermal systems. Epithermal precious metal systems may be classified as high, intermediate, and low sulphidation styles. They are characterized by the sulphidation state of the hypogene sulphide mineral assemblage, and show general relations in ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Mining operations at the Mulatos Mine consist of the Mulatos open pit complex and the Yaqui Grande open pit currently under development. Mining in the Mulatos open pit started in 2005. The open pit is a standard loader and truck operation running 24 hours per day, seven days per week. Mining is currently undertaken by a contractor and prior to 2014 mining was undertaken by Mulatos personnel. It is anticipated that the contractor will remain for the life of the open pit. Based on Mineral Reserves as of December 31, 2021, the Mulatos open pit complex (including stockpiled ore) has a remaining life of approximately two and a half years, excluding La Yaqui Grande.

The Company commenced full-scale construction at Cerro Pelon in the fourth quarter of 2018 and completed construction in October 2019 on budget and ahead of schedule. Ore from Cerro Pelon was trucked to a dedicated crushing facility adjacent to the Mulatos complex. Crushed Cerro Pelon ore was conveyed to the Mulatos leach pad for further processing. Mining of Cerro Pelon ceased in the fourth quarter of 2021 with the depletion of the deposit.

The Company is currently developing the La Yaqui Grande open pit operation. La Yaqui Grande will have its own dedicated crushing facility and leach pad. Loaded carbon will be transported to the Mulatos ADR for further processing.
