Results of First Drill Hole at Rudnitza

TETHYAN RESOURCES DRILLS 567 METRES AT 0.28% COPPER AND 0.45 g/t GOLD FROM SURFACE IN ITS FIRST DRILL HOLE AT THE RUDNITZA COPPER-GOLD PORPHYRY PROSPECT, SERBIA

 

Tethyan Resources PLC (“Tethyan” or the “Company”) (AIM:TETH) is pleased to announce completion of its 4 diamond drill hole programme (total 2,318 m) at the Rudnitza copper-gold porphyry prospect within the Suva Ruda exploration permit in Serbia. Tethyan  has received assay results for the first drill hole RDD-001. Assays for the remaining 3 drill holes are pending and a further announcement will be made in due course.

The results from drill hole RDD-001 are provided in Table 1 below:

Drill hole RDD-001 from surface intersected a thick package of dacitic volcanic rocks showing strong phyllic and propylitic alteration with extensive zones of thin (2-20mm) quartz – pyrite ± chalcopyrite veining and stockwork. Between 122 – 160 m a 38 m chalcocite-bearing zone of supergene enrichment was intersected giving an interval of 38 m at 1.18% copper and 0.38 g/t gold, although copper grades were lower in the leached zone above this interval gold grades remain consistent averaging 0.45 g/t gold. From a depth of 160 m gold and copper grades are remarkably consistent up to the intersection of a deeper ophiolite basement rock-type which was intersected between 567 and 584.6 m and where the gold and copper grades reduced. The drill hole was terminated due to drilling issues at 584.6 m still in mineralisation.Table 1: Coordinates are WGS84 UTM Zone 34.

Tethyan holds an option to purchase 100% of the Suva Ruda permit from local Serbian company Deep Research d.o.o. who acquired the permit in late 2015 (please refer to the press release dated 27th September 2016 for details). Phelps Dodge Corporation had initially identified the Rudnitza porphyry in 2004 and drilled 7 widely spaced drill holes over an area of 1.2 km by 0.8 km. The holes were centred on a porphyritic dacite stock with outcropping quartz stockwork occurring over an area 500 m by 450 m surrounded by a wider zone of phyllic and advanced argillic alteration. Three of the Phelps Dodge drill holes were drilled into the quartz stockwork, the other 4 holes were drilled on the periphery of the stock into phyllic alteration. These holes were drilled to depths between 170 and 300 m and did not test the porphyry at depth.

RDD-001 was drilled very near to the site of one of the earlier Phelps Dodge drill holes which had reported 144 m grading at 0.4% copper and 0.4 g/t gold but had been completed at 244 m still in mineralisation. The results reported here confirm the earlier data but, more importantly, indicates that porphyry copper-gold mineralisation continues to a far deeper extent at Rudnitza.

Fabian Baker, COO of Tethyan, commented: “We are very pleased with the results of this first drill hole, which validate Rudnitza as an exploration prospect with great potential. The fact that we did not encounter significant potassic alteration in this drill hole indicates to us that potential remains to expand the dimensions of this deposit and find a higher-grade core to this porphyry system. Following receipt of results from the remaining three drill holes Tethyan will be finalising its exploration program for 2017 to further develop the Rudnitza prospect.”

Sampling Methodology

Drilling and sampling procedures were carried out in-line with standard industry best practice. Drill core recoveries averaged in excess of 99%. Samples consisted of two metre composites of half drill core which were delivered to ALS Global in Bor, Serbia. Samples were prepared by drying, crushing to 70% less than 2mm, riffle split to provide a 1 kg sample which is pulverised to better than 85% passing 75 microns. Samples were analysed for gold by 30g fire assay and AAS, and for a 33 multi-element suite by four acid digestion and ICP-AES.
