The Oyu Tolgoi porphyry Cu-Au-(Mo) deposit is located in the Gobi Desert of southern Mongolia. The deposit consists of three main mineralized zones (North, Central, and South Oyu), interpreted to constitute at least two separate porphyry copper centers. Oyu Tolgoi is associated with a series of small, structurally controlled stocks and dikes …

A time-stratigraphic-structural sequence for the rocks is critical to defining the tectonic evolution of the belt. In the Oyu Tolgoi area of the South Gobi Desert (Mongolia), Devonian and Carboniferous rocks record the construction of multiple arcs, formation of a giant porphyry Cu-Au system, exhumation, and polyphase deformation.
chargeability anomaly over Central Oyu, whereas surface geochemistry identz3ed Central Oyu as anomalous in Cu, Mo and As. Better results from the first drill program included hole OT-3 at Central Oyu which intersected 30m @ +2% Cu and OT-4 at South Oyu with 73m @ 1.65% Cu and 0.15 g/t Au (Perello et a1.,2001).

Burial of the Cu-Au deposits at Oyu Tolgoi soon after their exhumation was critical to their preservation. Exhumation and subsequent burial occurred at ~371 Ma, during a short time frame within the overlapping U-Pb zircon ages for the quartz monzodiorite, mineralized porphyry clast, unmineralized dacite sequence, and granodiorite unit.
Oyu Tolgoi is expected to become the fourth-biggest copper mine in the world by 2030, operating in the first quartile of the copper equivalent cost curve.
