The Starra Line is a 52-kilometre-long geological structure that is strongly magnetite altered and hosts widespread copper-gold mineralisation. The six-kilometre section of this structure exposed in the Selwyn region hosts five mines that produced approximately 170,000 tonnes of copper and one million ounces of gold from 6.8 million tonnes of ore @ 2.1% copper and 4.6 grams of gold per tone between 1987 and 2002 (Ivanhoe, 2011).
Starra 222 is particularly gold-rich and produced 290,000 ounces of gold and 22,000 tonnes of copper from 2.2 million tonnes of ore @ 1.0 % copper and 4.1 grams of gold per tonne. Significant resources remained when mining ceased at Starra 222 in 2002 (Ivanhoe, 2011). Ivanhoe commenced drilling at Starra 222 in August 2010.
The remaining 46 kilometres of the Starra Line lie under approximately 5 to 50 metres of cover; approximately 10 kilometres of this strike are north of Starra 276 and the remaining 36 kilometres are south of Starra 222.
Indicated & Inferred reserves: 12.6Mt @ 0.6% Cu & 0.84g/t Au (2011)
