Sumatra Copper & Gold: W. Sumatra project update

(10 March 2010)--The Directors of Sumatra Copper & Gold plc are pleased to provide an update of activities at the Sontang project.

The Sontang project lies within the Pasaman IUP in the province of West Sumatra, some 160 kilometres north of Padang. The Pasaman IUP encloses an area of approximately 250 km2. Drainage geochemistry has previously delineated a significant polymetallic anomaly, and detailed mapping identified massive sulphide mantos style mineralisation in Sontang East were 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.

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.

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.

The more than 4 metre wide zone of dark grey, cryptocrystalline, jasperoidal silica exposed in the creek to the north of the gossan was sampled over the available outcrop and returned values of 2.63 g/t Au and 6.75 g/t Ag over a 4 metre interval. The outcrop lies on the edge of a NW-SE trending, 1,000 metre by 200 metre Au soil anomaly, which has been delineated at +25 ppb and +50 ppb Au contour levels and is strongly associated with the limestone complex.

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. The anomaly coincides with a number of intense silica-clay altered porphyritic dioritic intrusives noted in the first pass mapping and indicates a potential for high or intermediate sulphidation styles of mineralisation.

Work at Sontang is continuing with further soil sampling, mapping and sampling for exposures. It is hoped that drilling on the massive sulphide bodies identified will commence before the fourth quarter of 2010. (end of edited release)
