Reference information

Comments Grade: 0.26–0.33% Cu (0.3% Cu, in the average), 0.003–0.009% Mo (0.007% Mo, in the average). Geologically the deposit comprises of a Vendlockian–Ludlowian effusive-sedimentary bed of sandstones with interbeds of tuffs, gritstones and conglomerates found in the east and south of the area; of liparite and liparite-dacite lavas, tufaceous lavas, tuffs, ignimbrites, all probably of Upper Devonian age and which occur in the western and southwestern flanks of the deposit. A complex shaped intrusive body of plagiogranite porphyries strikes northwesterly for 2 km and has a thickness of 0.6–0.8 km. The contacts between the massif and the host rocks are steep and dip toward the center. Three varieties of intrusive rocks have been recognized: basic quartz plagiodiorite porphyrites, plagiogranite porphyrities with a predominant allotriomorphic granular or a granular mass, plagiogranite porphyries with a predominant felsite mass. Dikes of granite porphyries occupy faults around the plagiogranite porphyries. The ore-bearing quartz-sulfide stockwork is accompanied by quartz-sericite alteration, quartz-feldspar, and quartz-carbonate veinlets. Mineralization is pervasive. Orebody dimensions are 750–1900 m along the strike, 200–800 m down dip and 8–123 m thick. Discovered in 1954 by Volobuev V.I.
