Sept. 18, 2020 (GLOBE NEWSWIRE) -- Barrick Gold Corporation (NYSE:GOLD) (TSX:ABX) said today it accepted the Antofagasta Environmental Court’s decision to uphold the closure order and sanctions Chile’s environmental regulator imposed on Compañía Minera Nevada, the Barrick subsidiary that holds the Chilean portion (Pascua) of the Pascua-Lama project.

Barrick said the ruling drew a line under a legal process that started in 2013 and the company would not appeal it. Construction was suspended that year and Pascua would now be transitioned from care and maintenance to closure in accordance with the Environmental Court’s decision.

Deposit Type

  • Epithermal


Summary:

The Pascua-Lama property is located in the high Andean Mountains, in what has been designated as the Eastern Belt of Hydrothermal Alteration. The gold, silver, and copper mineralization and alteration assemblages at Pascua-Lama are associated with a structurally controlled acid sulfate hydrothermal system hosted by intrusive and volcanic rock sequences of Upper Paleozoic and Middle Tertiary age.

Alteration and mineralization is of the high-sulfidation, epithermal type. As is typical with high-sulfidation epithermal deposits, the principal metal commodities at Pascua-Lama are gold and silver – the copper content is usually sub-economic.

Numerous breccias bodies occur in the Esperanza, Quebrada de Pascua and Lama areas. At the surface, these breccias vary in size from outcrops measured in centimeters up to hundreds of meters. Typically the breccias show a strong correlation to zones of intersection of two or more major structural zones. Breccia Central, the large inter mineral breccia pipe, occurs in the Quebrada de Pascua area. On the surface, this breccia body is about 650 meters long and up to 250 meters in width, while underground, between 200 and 400 meters below the surface, the composite body measures about 550 meters in length and up to 130 meters in width. It extends to at least 700 meters below surface. This well mineralized breccia pipe is evidence of an explosive hydrothermal event related to the formation of the Quebrada de Pascua ore deposi ........
