Tethyan Commences TDIP Survey and Additional Exploration at Kizevak

Jersey, England--(Newsfile Corp. - September 24, 2018) - Tethyan Resources plc (TSXV: TETH) ("Tethyan" or the "Company") is pleased to announce that it has contracted Terratec Geophysical Services GmbH ("Terratec") to conduct a Time Domain Induced Polarisation (TDIP) geophysical survey on the Kizevak zinc-lead-silver prospect, located within Tethyan's Kremice exploration licence in Southwest Serbia.

The TDIP survey has been designed to test a zinc-lead-silver ± gold soil anomaly at the Kizevak Southeast and Kizevak South prospects, which includes the along strike and down dip extensions of mineralisation intercepted in drilling as announced by Tethyan on September 4^th, 2018. The survey will be conducted over an area of approximately 1.6 by 1 kilometres with a line spacing of 80 metres and is designed to test up to 350 metres below surface, depending on the line length. It is anticipated that clay-pyrite alteration which is associated with polymetallic mineralisation will generate chargeabilty anomalies and therefore aid in designing follow-up drill programmes.

Tethyan is also conducting a trenching and channel sampling program in the same area for approximately 400 metres, and anticipates the arrival of a recently acquired magnetometer and base station within the next six weeks. The magnetometer will initially be used to conduct ground magnetic surveys over priority targets at the Kremice and Kaznovice exploration licences to assist with interpreting structure and zones of magnetite destructive alteration.

Andrew Tunningley, Exploration Manager for Tethyan, commented "Recent drilling results from the Kizevak Southeast prospect demonstrate that high-grade polymetallic mineralisation is coincident with the soil anomaly and comprises sphalerite-galena-pyrite-arsenopyrite vein breccia and fracture fill mineralisation hosted in weakly to moderately clay-pyrite altered andesite. The clay-pyrite alteration is magnetite destructive and is restricted to a fault zone which is inferred as the primary control on mineralisation. The TDIP survey is therefore designed to define the extent of chargeability anomalies potentially associated with the clay-pyrite alteration. The results of the TDIP survey will be assessed together with soil sampling analyses, trench data and magnetic survey results to define additional targets at Kizevak for drilling later this year".
