Tethyan Resources PLC announced results of the remaining 3 drill holes following the completion of its 4 diamond drill hole programme (total 2,318 metres) at the Rudnitza copper-gold porphyry prospect within the Suva Ruda exploration permit in Serbia. Highlight intersections of these drill holes include: Drillhole RDD-004 356 m @ 0.38% copper and 0.31 g/t gold from 48 m (including 30 m @ 1.45% Cu and 0.39 g/t Au from 102 m) and Drillhole RDD-003 285 m @ 0.31% copper and 0.33 g/t gold from 42 m (including 16.7 m @ 1.55% Cu and 0.20 g/t Au from 102 m). These three additional drill holes have significantly expanded the footprint of copper-gold porphyry-style mineralisation at Tethyan's Rudnitza prospect, which had previously been identified in RDD-001. This drill hole intersected 567 metres at 0.28% copper, 0.45 g/t gold, as announced on 16 January 2017. The latest drilling has expanded the size of mineralisation identified to an area of at least 300 metres by 200 metres horizontally and up to 500 metres vertically. This drilled zone of mineralisation is contained in a much larger intensively altered volcanic sequence with anomalous copper, gold and molybdenum in soils which extends for up to 1,500 metres in a north-south direction and 500 metres east-west. All drill holes intersected a thick package of dacitic volcanic rocks showing strong phyllic and propylitic alteration with extensive zones of thin (2-20mm) quartz-pyrite±chalcopyrite±chalcocite veining and stockwork. Supergene enrichment has produced a higher-grade chalcocite rich copper zone observed in each of the drill holes that is in excess of 1% copper. Drill Hole RDD-004 intersected 30 metres at 1.45% copper, 0.39 g/t gold from 102 metres. Copper grades are generally seen to be lower in the leached zone above this supergene zone however gold mineralisation was encountered from surface. Beneath the supergene zone gold and copper grades are generally consistent over large intervals exceeding 200 metres. The Company has completed a ground magnetics survey and is planning an extensive induced polarization (IP) geophysical survey over this area to target further drilling. A second program of drilling is planned for the second half of 2017 following processing and interpretation of the geophysical surveys.
