The Haquira project is located in the Oligocene Andahuaylas-Yauri Belt of southern Peru (Figure 1). The region encompasses parts of the intermontain depressions between the Eastern and Western Cordilleras and the northern extremity of the Altiplano. The western part of the belt is characterized by a rugged, mountainous topography where ranges and snow-capped peaks above 4,500 meters are incised by deep (>2,000 metres), steep-sided canyons. These canyons constitute the main drainage systems of the region and include the Santo Tomás, Urubamba, Apurímac, Vilcabamba, , Mollebamba, and Atabamba rivers, all of which drain towards the Amazon basin. The eastern and southern parts of the region are characterized by the gently undulating topography of the 4,000-meter-high plateaus that extend into the Altiplano of Bolivia. The northern part of this belt is characterized by east-west-striking, north-verging Cretaceous thrust faults, which is a trend transverse to the north-northwest-trending magmatic arcs in Peru. The Oligocene magmatism trends east-west and intrudes the faulted and folded Cretaceous sedimentary sequence.
The Andahuaylas-Yauri belt is host to significant skarn and porphyry-style Cu ±Au ±Mo mineralization and includes the skarn (Tintaya, Coroccohauyco) and porphyry copper deposits (Quechua, Antapaccay) of the Tintaya district, as well as the skarns in the Bambas district, and the Los Chankas porphyry copper deposit. The Haquira project is located in the Oligocene Andahuaylas-Yauri Belt of southern Peru within a feature referred to as the Abancay Deflection (Figure 1).
