Mine Life2026
The La Coipa mine and plant suspended activities in October 2013, and in February 2020, following a positive feasibility study, Kinross approved the La Coipa Restart project.

The project commenced production from the Phase 7 deposit in Q1 2022.

Deposit Type

  • Epithermal
  • Breccia pipe / Stockwork
  • Vein / narrow vein


Summary:

The La Coipa mine consists of eight deposits (notable deposits being Phase 7, Puren, Coipa Norte, Ladera Farellon and Can Can). The deposits in the La Coipa district are typical of high-sulphidation epithermal systems produced by volcanism-related hydrothermal activity at shallow depths and low temperatures. Deposition normally takes place within 1 km of the surface in the temperature range of 50°C to 200°C, although temperatures up to 400°C are not uncommon. Most deposits occur as siliceous vein fillings, irregular branching fissures, stockworks, breccia pipes, vesicle fillings and disseminations. The fissures have a direct connection with the surface, which allowed the ore-bearing fluids to flow with comparative ease. In many cases the deposits are related directly to deep seated intrusive bodies; it is typical for most ores to be in or near areas of Tertiary volcanism. The country rocks located near epithermal veins are commonly extensively altered. Relatively high porosity and open-channel permeability allow fluids to circulate in the wall rocks for great distances. Favourable temperature gradients promote reactions between cool host rocks and warm to hot invading solutions. As a result, wall-rock alteration is both widespread and conspicuous. Among the principal alteration products are chlorite, sericite, alunite, zeolites, clays, adularia, silica and pyrite. The mineralization at La Coipa displays intense zoning and is characterized by an upper zone of secondary Ag ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The La Coipa open pit gold mine is located in the Maricunga mining district in the Atacama Region of northern Chile, approximately 1,000 kilometers north of Santiago and 140 kilometers northeast of Copiapó.

Until October 2013, La Coipa operated two pits (Ladera-Farellon and Can Can). Mining was carried out with front-end loaders, diesel rotary drills and 150-tonne trucks.

The mine and plant suspended activities in October 2013.

In February 2020, Kinross completed and approved a Feasibility Study to restart operations at La
Coipa by mining the Phase 7 deposit.

Pre-stripping began in January 2021 with production starting in Q1 2022.

The project plan included refurbishing the existing process plant, camp and other infrastructure, as well as relocating the mining fleet (Cat 785C trucks and 994 wheel loaders) from the Maricunga operation, which was placed on care and maintenance in 2018.
