Sumatra Copper & Gold updates mineral resource estimate

By Ruli Setiawan

ASX-listed Sumatra Copper & Gold plc announce on Tuesday that updated Mineral Resource estimates have been completed for the key Berenai, Asmar, Tembang/Anang and Bujang deposits at its flagship Tembang Gold-Silver Project in Sumatra.

The updated Mineral Resource estimates follow completion of the 6,985 meters Mineral Resource drilling program at Tembang which was undertaken as part of the company?s optimized development strategy.

No updates have been made to the Siamang and Belinau Mineral Resources as the Company chose to restrict the additional drilling at these projects during the recent drilling campaign. The Siamang deposit was previously reported as part of the Buluh deposit, although it is currently expected that only the Siamang deposit will be considered as a potential open pit mine.

Both the Belinau and Buluh Mineral Resource estimates were updated and were reported to the ASX on 4 December 2013 and are considered compliant with the JORC Code (2012 Edition).

The updated Mineral Resource estimates are summarized in Tables A1 to A4 below.
