Four holes were drilled and the results from the first are already in.
This showed an encouraging 38 metres at 1.18% copper, with gold at 0.38 grams per tonne. Gold grades throughout the 567 metre hole averaged at around 0.45 grams per tonne.
The drill hole terminated in mineralisation and was drilled very near to the site of an earlier Phelps Dodge drill hole which had reported 144 m grading at 0.4% copper and 0.4 g/t gold. This earlier hole had been completed at 244 metres depth, but was also still in mineralisation.
Taken together, the results indicate 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. 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."
