Tethyan Announces Results of New Drill Holes at Rudnitza Copper-Gold Prospect, Serbia

JERSEY, UK, Sept. 14, 2017 /CNW/ - Tethyan Resources PLC (AIM:TETH) (TSX-V:TETH) ("Tethyan" or the "Company") is pleased to announce results of the drilling programme completed in July 2017 at the Rudnitza copper-gold porphyry prospect within the Suva Ruda exploration permit in Serbia. This drill programme consisted of 4 diamond drill holes for a total of 2,127.6 metres.

Highlight intersections from these drill holes include:

• Drill hole RDD-006 460 m @ 0.21% copper and 0.20 g/t gold from surface
  (including 20 m @ 1.04 % copper and 0.20 g/t gold from 92 m)
  
  and
  
  
• Drill hole RDD-005 260 m @ 0.22% copper and 0.20 g/t gold from 6 m
  (including 12 m @ 0.78% copper and 0.13 g/t gold from 116 m)

Assay results details are provided in Table 1 below:

Fabian Baker, COO of Tethyan, commented: "We are pleased that further drilling at Rudnitza has confirmed that this is a very extensive mineralised system. These results show good continuity and significantly add to our understanding of the geological setting of the mineralisation. Rudnitza is evidently a large mineralised system with numerous zones as yet undrilled."

The results of these drill holes have expanded the known extent of the Rudnitza porphyry system, and have returned long intervals of porphyry-style stockwork copper mineralisation hosted in multi-phase porphyritic dacite/diorite intrusions. The true widths of the drill intersections cannot be determined with the information available as mineralization is disseminated throughout this large system.

Tethyan's geologists, with support from highly experienced consulting geologist Simon Meldrum, are currently interpreting the results and drill core logging with the aim of vectoring towards higher-grade mineralisation in future drilling. At least five phases of porphyry intrusives have been identified in the drill core, each with variable styles of alteration and intensities of mineralisation. It is evident that certain intrusive phases are better mineralised than others. Tethyan's future exploration and drilling will focus on targeting these higher grade units.

The surface expression of the Rudnitza porphyry system is characterised by coincident copper, gold and molybdenum geochemical soil anomalies which Tethyan has defined over an area of approximately 1,500 m N-S and 600 m E-W. Drilling to date has been restricted to a small area in the southern end of the anomaly. A summary of all of results of Tethyan's drilling at Rudnitza to date is provided in Table 2 below.

The technical information in this news release has been reviewed by Tethyan's Chief Executive Officer, Peter Mullens, FAusIMM, who is a Qualified Person as defined by National Instrument 43-101. 

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% passing 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.
