DRILLING COMPLETED ON THE RUDNITZA COPPER-GOLD PORPHYRY PROSPECT WITHIN THE SUVA RUDA PROJECT, SERBIA

Tethyan Resources PLC ("Tethyan" or the "Company"), has completed 4 diamond drill holes for a total of 2,318 meters on the Rudnitza copper-gold porphyry prospect within the Suva Ruda exploration permit located in Serbia.

The drilling program, which was operated by contractor Drillex International d.o.o., successfully achieved the Company's objectives through consistent drilling rates and positive local community support.

In accordance with the requirements of the Option Agreement between Tethyan and Deep Research d.o.o. over the Suva Ruda Project (please see announcement of 27 September 2016 for details), Tethyan has successfully met the requirement to drill 2,000 meters prior to the 28th December 2016 in order for the Option Agreement to remain in effect. Furthermore, it meets the exploration programme requirements set out for the Suva Ruda License granted by the Serbian Government.

Tethyan's geologists are currently logging and preparing the drill core for third party analysis and final results can be expected to be announced in late-January 2017. Additionally, Tethyan is immediately rehabilitating the drilling sites and access roads in accordance with the Company's commitment to sustainable operation.

Fabian Baker, COO of Tethyan, commented: "We are pleased with the timely completion of our first drilling programme at Rudnitza, which is a good testament to our local team and the operating environment in Serbia. We achieved the meters that we set out to complete, which holds the Option Agreement in good standing and will give us a good initial understanding of the local geology and extent of copper and gold mineralisation on the prospect. We look forward to announcing the results in late January and preparing for the next phase of exploration to commence on the project in the spring of 2017."
