A porphyry gold deposit in western Turkey’s Usak province is providing
Drilling to date at the Kisladag project has outlined a large, elliptically shaped gold deposit measuring 600 by 400 metres, with a weakly mineralized central core. The eastern portion of the deposit contains a higher-grade zone, varying from 40 to 120 metres in width along a strike length of more than 300 metres. Drilling in this zone has returned average grades of more than 3 grams. Both the deposit and the high-grade zone remain open at depth and to the east.
The encouraging results have prompted Eldorado to step up the pace of work at Kisladag. Earlier this year, the company completed 1,050 metres of drilling. The current, 26-hole program is designed to test the deposit on 100-metre spacings to depths of 200 to 300 metres.
Results are in hand for the first 13 holes. The 247-metre intersection includes a 58-metre interval of 4.27 grams and a 26-metre interval of 5.39 grams. Other results include: 160 metres of 1.54 grams; 148.4 metres of 1.68 grams; and 297.5 metres of 1.99 grams. The remaining holes returned wide intersections grading below 1 gram, most of which included higher-grade intervals.
Gold mineralization is found in multi-stage, quartz stockworks associated with sulphides and hydrothermal alteration. Sulphides consist of pyrite, with traces of molybdenite, sphalerite, galena and chalcopyrite. Strong potassic alteration forms the core of the higher-grade zone, grading outward into argillic and chloritic alteration.
Metallurgical test work is under way. Once the drilling and metallurgical tests are complete, a resource estimate will be prepared, to be followed by scoping studies.
