Sumatra Copper & Gold

Sumatra Copper & Gold (ASX:SUM) was established in 2006 to explore for, and develop, gold-silver and copper-gold mineral deposits on the Indonesian island of Sumatra. The Company has an economic interest of 92.5% in its projects.

Sumatra has two main brownfield projects – Tembang and Tandai (which is held in JV with Newcrest) and a main exploration project, Sontang. Tembang’s combined measured, indicated and inferred JORC resource is 1,000,500 ounces of gold and 13,121,300 ounces of silver, with further exploration upside potential

Sumatra Copper & Gold receives encouraging results from Sontag project

Wednesday, March 10, 2010

Sumatra Copper & Gold plc (ASX: SUM) has provided an update at the Sontag project in the province of West Sumatra, some 160 kilometres north of Padang.

Managing Director, Jocelyn Waller, said: “We are very excited by the new results from Sontang. The discovery of further mantos, plus the large gold anomaly and results from the jasperoidal veining together with the new copper-arsenic target indicate that this is a much larger and more complex system than previously thought.”

Recent activity at Sontang during January and February 2010 has focused on tracing mineralisation from Sontang East north-westwards to the Sontang Central and Sontang West prospects with a program of ridge and spur soil sampling at 25 metre intervals.

The geochemistry has been undertaken in conjunction with surface mapping.

Geochemistry has previously delineated a significant polymetallic anomaly, and detailed mapping identified massive sulphide mantos style mineralisation in Sontang East where the weighted-average metal contents for 54.8 meters of rock-channel samples was 2.87g/t Au, 118g/t Ag, 0.57% Pb and 5.66% Zn.

Two new outcrops were located within Sontang Central, one a gossanous massive sulphide mineralisation in meta-sediments, the second of jasperoidal silica mineralisation.

Results from the new massive sulphide outcrop at Sontang Central gave 10 metres (8.5 metres true width) @ 0.14 g/t Au, 765 g/t Ag, 8.3% Pb, and 1.78% Zn.

A new jasperoidal outcrop at Sontang Central returned 4 metres at 2.63 g/t Au and 6.75 g/t Ag.

Additionally, results from ridge and spur soil sampling have outlined a significant copper-arsenic soil anomaly, marked above +110 ppm Cu (maximum 420 ppm Cu) and +140 ppm As (maximum 4,020 ppm As), that is at least 400 metres by 400 metres in size, at Sontang West.

Work at Sontang is continuing with further soil sampling, mapping and sampling of exposures. The company hopes to commence drilling on the massive sulphide bodies already identified before the fourth quarter of 2010.
