Sastavci Project

RELATIVELY UNTESTED BUT PROVIDES UPSIDE AND SYNERGIES

Sastavci was also mined historically by open pit on a smaller scale than at Kizevak and represents a priority drilling target.

Outcropping, steeply dipping, massive sulphide veins up to 5 m wide are visible in the pit walls (an accumulated width of >250m). Mineralisation at Sastavci occurs over a strike length of 1.2km.

SIMILAR MINERALOGY AND STYLE TO KIZEVAK

The similar mineralisation style includes veins and lenses of sulphide-quartz-carbonate, hosted in andesite volcanics with clay-silica-pyrite selvedges. Sastavci in hand-specimen appears more quartz-rich than Kizevak, with disseminated arsenopyrite and coarse galena-sphalerite.

Tethyan collected 65 rock-chip samples across the Sastavci area, which returned assays ranging from trace to >30% Zn (over range), 7.1% Pb, 94.3g/t Ag and 0.47g/t Au in the Sastavci pit.

A historic resource estimate is reported in the Serbian geological archives.

Additionally, to the north of the Sastavci open pit Tethyan has defined a greater than 100ppb Au in soil anomaly over 800 m long and 400 m wide in strongly silica altered volcanic rocks.

Rock-chip sample assays range from trace to 3.7g/t Au, representing a separate epithermal Au exploration target.
