TOPIC: “The Turquoise Hill (Oyu Tolgoi) Project, south Gobi Desert, Mongolia”
The Turquoise Hill (Oyu Tolgoi) project is located in the south Gobi desert of Mongolia, approximately 650 km south of the capital city of Ulaan Baatar.
In 1996 a team of BHP geologists inspected known copper occurrences in the area and identified porphyry-related quartz stockwork veining in leached outcrops at central Oyu. Subsequently BHP conducted a three year exploration program including 23 widely spaced diamond holes. Ivanhoe Mines acquired an option to purchase the property in 1999 and since that time has carried out extensive reverse circulation and diamond drilling which has resulted in the discovery of a major gold-rich porphyry copper deposit at southwest Oyu.
The most recent resource estimates are 356 mt @ 0.95% CuEq (0.48% Cu & 0.73g/t Au), Indicated and 1317 mt @ 0.98% CuEq (0.86% Cu & 0.19 g/t Au), Inferred. Another 860 mt of 1.08% CuEq (1.01% Cu & 0.1 g/t Au), Inferred has been estimated for Far North Oyu (Source Data). CuEq is calculated on the basis of US$0.80/lb Cu and US$350/oz Au.
