ABSTRACT:Sumatra Copper & Gold plc (“the Company”) announces its Annual Mineral Resource and Ore Reserve Statement, completed in accordance with the guidelines of the JORC Code (2012 Edition), for its Tembang Gold-Silver Operation in southern Sumatra, Indonesia (“Tembang”).Cube Consulting Pty Ltd (“Cube”) of Perth, Western Australia, was contracted by the Company to complete a review and update of the Mineral Resource estimates for the Belinau and Berenai gold-silver deposits, which are currently subject to underground and open-pit mining operations respectively. A site visit was undertaken by Cube’s designated Competent Person (CP) between 6 and 13 December 2016. The CP was already familiar with Tembang, and other Cube CPs had previously made visits to Tembang. The Belinau Mineral Resource is currently being exploited from underground via decline access from within the former Belinau open pit. The Berenai Mineral Resource estimate encompasses the Berenai, Nuri and Central vein systems, within one open pit mining operation. The Belinau and Berenai Mineral Resources have been predominantly defined by diamond drilling and lesser reverse circulation (RC) drilling, and newly acquired grade control data from more recent RC and blast hole drilling, trenching, face mapping and sampling, and bench mapping and sampling. The previous mineralisation interpretations of the Belinau and Berenai deposits have both been reviewed and revised by Tembang mine geology personnel, under the supervision of consulting geologist, Mr Gary Powell, and Cube’s CP, using the more recent data acquired during mining operations. This has had a material effect on the estimation strategy employed by Cube for both deposits.
