Production Start...
Altiplano has extracted ore at Farellon since Q1 2018. Proceeds from the sale of mineralized material are credited to exploration and evaluation properties. The decision to commence production on the Farellon deposit is not based on a feasibility study of mineral reserves.

On June 23, 2022 processing facility at El Peñón receiving final permitting approval and commencing start up. The first concentrate expected to be produced for shipment in July. Production from Farellon will be split shipped to the facility and ENAMI for the next few months to maximize copper sales while the plant ramps up to full operational capacity.

Deposit Type

  • IOCG
  • Vein / narrow vein


Summary:

Deposit types found in the La Serena region of northern Chile include massive magnetite, Manto-Style copper-(silver), iron oxide-copper-gold (IOCG) deposits, and copper-gold veins potentially related to porphyry systems. These deposits are found within the early-Jurassic to mid-Cretaceous rocks, and appear to be formed through regional faulting and extension and localized structural systems. Review of the historic literature and a site visit completed by the authors determined that the primary exploration target for the Farellon project is copper-gold veins as each comprise high-grade structures with these metals.

The Farellon area lies in the contact zone between regional granodiorite and diorite bodies to the west and north respectively, as well as Cretaceous-aged formations of stratified rocks including volcaniclastic sediments, tuffs, limestones and sandstones. The proximity of the intrusive bodies produced contact metamorphism (hornfels) and metasomatism, resulting in areas of skarnification and strong silicification (Denmark, 2008).

The intrusions and subsequent movement produced a complex structural system. The dominant fractures in the stratified rocks and intrusive rocks are orientated between 50o (northeast) and 75o (east-northeast).

Secondary fracturing is mainly in an east-west orientation, with sporadic downdropping of the rocks to the south (Denmark, 2008).

Mining Methods

  • Drift & Fill


Summary:

Altiplano has been recovering Cu-Au mineralized material from an underground decline through a series of drifts.

As part of ongoing development underground at Farellon, the Company has advanced the Hugo decline from the initial 395m level to the 389, 382, 376, 368 and 360 m levels. The advancement of the decline provides access to deeper parts of the vein system.
