Abstract Explora tion, d is covery and res ource de ve lopment Abs trac t The Caspiche property is located in Region III, Chile, within the Maricunga belt, a metallogenic province which hosts numerous large epithermal and porphyry gold±silver±copper deposits. In September, 2009, Exeter upgraded its Caspiche inferred resource to 19.6 million ounces of gold and 4.8 billion pounds of copper. Anglo was the first company to explore the Caspiche area. Between 1986 and 1990, they explored and drilled 1,518 m in 12 holes aimed at assessing the potential of a silica ridge located in the centre of the Caspiche property. They found the target to be too small and the property remained idle until 1996 when it was optioned by Newcrest. Newcrest was initially interested in the porphyry potential of the property. They undertook systematic surface sampling, mapped, ran dipole IP-Resistivity, and drilled 3,218 m in 14 holes, 12 of these aimed at testing the porphyry potential on the Caspiche Porphyry prospect. They reported porphyry mineralisation of sub-economic grades. In 1987 Newcrest flew a helimag survey which defined a strong magnetic high anomaly in the southwest of the Caspiche Porphyry prospect. During the 1997-98 season they drilled a further 4,123 m in 22 holes. An epithermal system 3 kilometres to the east of the Caspiche Porphyry was the focus of their drilling.
