STATE REVIEWS Table – 3: Details of Exploration Activities in Maharashtra, 2015-16 Agency/ Location Mapping Drilling Sampling Remarks Mineral/ Scale Area No. of Meterage (No.) Reserves/Resources estimated District (sq km) boreholes GSI Base me tals (Cu, Pb & Zn) Bhandara Silejhari area, 1: 2000 1.0 - - - G-4 investigation has been carried out. Soil samples were collected on 100 m x 200 m grid, pitting & trenching of 50 Cu m along with collection of pitting-trenching samples (PTS) and bed rock samples (BRS) for chemical analysis. The lithologies of the study area belong to Gaikhuri and Dhabetekri Formation of Sakoli Group and basement Amgaon Gneiss. Disseminations of sulphide minerals, which include mainly pyrite, chalcopyrite, covellite, sphalerite, etc. are observed in chert bands and metabasalt west of Silejhari and northeast of Jhari areas. Bedrock samples from different locations of investigated area reveal that the Zn values vary from 10 ppm to 0.12% with average value of 381 ppm, Pb values vary from 10 ppm to 0.23% with average value of 383 ppm and Cu values vary from 10 ppm to 345 ppm with average value of 102 ppm. Further exploration work in the area is not recommended because of very low concentration of Zn and Pb. The investigation is completed. (Contd.) 11-5 STATE REVIEWS Table - 3 (Contd.) Agency/ Location Mapping Drilling Sampling Remarks Mineral/ Scale Area No. of Meterage (No.) Reserves/Resources estimated District (sq km) boreholes Chandrapur Minjhari area 1: 2000 1.5 4 500.0 - G-3 investigation has been carried out to establish copper and associated mineralisation. The basemetal mineralisation (Cu+Au) is confined to en- echelon dilational quartz veins stretching for 3.0 km strike length. The trend of the quartz reef changes from N15oW-S15oE in the northern part to N10oE- S10 o W in the southern part. The width of quartz vein varies from 2 m to 30 m and maximum length of individual exposure is about 1 km. Chemical results of five core samples from borehole (MHCM-3) showed good copper concentration with a maximum value up to 0.57%. Drilling in two different surface levels indicated deeper oxidation characteristics and deep seated mineralisation. In the first borehole (MMHCM- 1) two mineralised zones were identified i.e. Zone-1 from 78.00 m to 83.75 m with 0.23% Cu and Zone-II from 92.25 m to 98.55 m with 0.20% Cu. In the borehole (MHCM-2) two mineralised zones can be demarcated i.e. Zone-1 from 63.5 m to 66.5 m with 0.23% Cu and Zone-II from 67.80 m to 69.00 m with 0.20% Cu. In the borehole (MHCM-3) again two mineralised zones can be demarcated based on chemical results.i.e.Zone-I from 129.20 m to 136.20 m with 0.50% Cu and Zone-II from 142.95 m to 145.05 m with 0.43% Cu. The investigation will be continued in FS 2016-17. (Contd.) 11-6 STATE REVIEWS Table - 3 (Contd.)
