The first drill hole is centred on the dacite porphyry and phreatomagmatic breccia complex with quartz-veinlet stockworking at Buenavista, and is initially targeted to a depth of about 750m. The...
Escondida is a giant supergene enriched and hypogene open pit porphyry copper deposit located in northern Chile, some 160 km to the ESE of Antofagasta (#Location: 24° 16' 17"S, 69° 4' 13"W). Escondida is the largest of a cluster of related porphyry deposits in the surrounding district. The others include Escondida Este, Escondida Norte, Zaldívar, Pinta …
Life spans and thermal evolution of hydrothermal systems are of fundamental metallogenic importance. We were able to establish the chronology and cooling history of the Zaldívar porphyry copper deposit (Northern Chile) by applying a combination of different isotopic dating methods in minerals with different closure temperatures, including 40Ar/39Ar …
The Escondida deposit, located in the Andes copper belt of northern Chile, is the third largest porphyry copper deposit in the world with copper reserves of 31.567 millon tons.

Geology of the Zaldívar deposit The Zaldívar porphyry copper deposit is located in the Atacama Desert of Northern Chile, approximately 175 km SE of Antofagasta city (Fig. 1). The current proven and probable ore reserves are estimated at 421.3 million metric ton (Mt) at 0.67 wt.% Cu, equivalent to 2.83 Mt of copper.
This made it one of the largest porphyry ore deposits globally. However, continued drilling was able to upgrade this resource to ~31.3 billion pounds of copper and ~25.3 million ounces of gold,...
The Zaldivar porphyry copper deposit, Northern Chile, consists of two major intrusions, the 290 Ma Zaldivar, and the more recent Miocene (38.7 Ma) Llamo porphyry. Five types of …
The Zaldivar porphyry copper deposit is a smaller mine located about 5 km to the north of the Escondida deposit. The Llamo Porphyry, a dacitic feldspar–biotite–quartz porphyry (38·7 ± 1·3 Ma, zircon U–Pb age; 37·40 ± 0·18 Ma, biotite 40 Ar/ 39 Ar age), is spatially associated with the ore and is regarded as the source of ...

Zaldívar is an open-pit heap leach copper mine. The deposit, which is located at an average elevation of 3300m above sea level, forms part of a large Tertiary porphyry copper system that also includes the Escondida mine. Wood Mackenzie's asset reports are built from the bottom up, incorporating a number of granular data metrics to …
The Zaldı́var porphyry, the oldest of all units, is the most extensive intrusive unit observed in the mine. It outcrops only on the eastern side of the Portezuelo fault, and contacts the andesite across this structure. The porphyry typically consists of a gray rhyolite, with a well-developed coarse porphyritic texture.

Around 80% of Chilean copper production comes from copper-moly porphyry deposits, with most situated in northern Chile. These porphyries, which may contain minor gold and often have minor silver by-products, provide the ore for some of the world's most prolific and highest-grade copper mines.

Two discrete porphyry copper systems coexist at Zaldívar: Early Permian and late Eocene. The minor, copper-only Early Permian event (~290–285 Ma) was associated with an evolved, end-stage rhyolite porphyry phase of the La Tabla magmatism. The major late Eocene event (38.6–36.1 Ma) produced copper in addition to gold, …
