ABSTRACT:Sumatra Copper & Gold plc (“the Company”, ASX:SUM) is pleased to provide the following drilling update under the strategic alliance with PT Merdeka Copper Gold (Merdeka), whereby Merdeka covers the cost of the program and will be compensated with shares in the Company. Since February 2018, 17 diamond core holes for 5,028m have been completed In the 3 holes completed to date testing for extensions to the Belinau underground mine, the expected structures are all present. Although the quartz textures appear favourable for epithermal-style mineralisation, the veins in the two holes drilled directly beneath the mine (RDD18544 and RDD18548) were weakly mineralised ( An Exploration Target of 70,000 to 140,000 tonnes at grades of 7.5 to 11g/t Au for 15,000 to 50,000 oz Au has been estimated for three areas (Refer Figure 1) targeted in the underground drilling program at Belinau. The grades and tonnages are based on the grade control model within the existing mine. The grade control tonnes and grade from Levels 9 to 12 (35 vertical metres) with a 370m strike length totalled 36,000t at 11.2g/t Au and 25.1g/t Ag. A second grade control area from Levels 6 to 12 (100 vertical metres) totalled 65,000t at 12g/t Au and 60.6g/t Au. These grades and tonnage per area were applied to the area of proposed drilling below. The target tonnage was assigned a range from 50-100% of these volumes.
