Berta, located about 50km south of the Black Sea, is a joint venture with Xstrata Copper. The Berta porphyry is reputed to be the largest copper anomaly in the Turkish Pontides, covering 15km3. Extraordinarily anomalous copper has been obtained in drilling, most notably from hole SD-07-08 that intersected 710 metres of 0.28% Cu, with grades peaking at 30% Cu and 7.19% Zn. These results were followed up by further positive intersections, including Hole SD-08- 09 which returned 459m of continuous copper-gold mineralization starting from only four metres below surface and grades of up to 5.07% copper over 4.5m. Results from this hole include 179.9m grading 0.31% copper and 0.31g/t gold within a longer interval of 459m grading 0.17% copper and 0.17g/t gold. Of particular note is the presence of mineralization near surface in both drill holes. These results highlight the tremendous potential of the essentially unexplored Berta property.
Drilling in 2012 has added to these past results by returning consistently copper-anomalous results. All of the holes drilled to date at Berta have returned copper mineralization. The drilling indicates the huge scale and continuity of the anomaly in the Berta porphyry system. The wide spacing of the drill holes and the long intercepts obtained continue to demonstrate the scope of the copper mineralization at Berta. The property remains a very large and very prospective exploration opportunity.
