Reference information

Comments Cu-Mo porphyry target discovered by L. Krasny and Y. Chemekov in 1951. Cu-pyrrhotite target Olgondo (“Yellow hill”) is located on the opposite bank of Olgondo River. Metasomatic zoning from stock away: (Bi+Qrtz) – (Mu+Bi+Qrtz) – (And+Mu+Qrtz) – (Qrtz+Ser). There is 5-km-long NNE extended soil Mo anomaly (10 ppm Mo). Mineralization zone is 300 x 100 m. There is veinlet, disseminated, and lens shaped sulfide mineralization (pyrite, bornite, chalcopyrite(?), pyrrhotite; total 1–20%). Silicified rock with intensive impregnation of pyrite, chalcopyrite, bornite, covellite are recognized in northern direction for 4–5 km. Limonite (G+J) replaces not more then 50% sulfides at Olgondo-1 and Intensive limonitization (G+J) presents only on cracks at Olgondo (Yellow Hill).
