All the boreholes were planned at 120 m vertical depth of intersection and 200 m strike spacing. Four Boreholes have successfully intersected primary mineralised zone. Based on the chemical analysis of core samples from different boreholes, mineralised lodes are demarcated. The loads are varying grades (0.20 to 0.50% of Cu) and thickness (2.0 to 16.65 m) with a maximum of 4.26% Cu over 1.05 m width. The gold concentration in different boreholes is also erratic in nature and varies from 25 to 420 ppb. G4 stage investigation was taken up REE and RM Ghuksi 1:10000 7 5 - - - for locating REE and RM Nagpur granite mineralisation in Ghuksi granite. Two major pegmatite bodies were identified near Ghuksi village. Bedrock and stream sediment samples of granitic and pegmatitic terrain located at north of Ghuksi village have yielded the highest total REE values of 0.612% and 1.23% respectively. These zones are potential for REE and RM mineralisation. In SEM-EDX study REE bearing minerals such as zircon, monazite, allanite, xenotime and apatite were observed. G3 level preliminary exploration Nawegaon - - - 601 182 was carried out for REE and RM Goreghat through detailed exploration Chawari areas (Auger drilling) in Nawegaon- Goreghat Chawari areas. Auger drilling of 601 m was carried out in Junewani, Umri and Nawegaon area. A total of 182 samples was (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 collected. The auger samples were processed by panning to separate heavy fractions sent to chemical lab for petro-mineralogical studies. G4 stage reconnaissance survey was Sindhudurg Kaladgi 1:12500 100 - - - carried out for delineating REE rich and associated minerals by large scale mapping. Based on the chemical results of 254 of talus/regolith sample and all 65 panned SSS showing total REE ranging in between 1000 and 2243 ppm and 26 samples in between 500 and 1000 ppm. The rock type is porphyritic granite/granite gneiss with numerous pegmatite and quartz veins. In SSS the highest value of total REE is 951 ppm and highest value of Zr is 13,399 ppm. On the basis of anomalous analytical results, a 7 sq km area has been demarcated and explored by pitting. Baryte G4 stage reconnaissance survey for Chandrapur Naleswar- 1:12500 150 - - - baryte and associated mineralisation Tukum area was carried out. There are three parallel shear/fault zones, trending NNW-SSE within the Mul Granite, on which the veins of barite occur as intrusive. Baryte is associated with sulphide minerals such as disseminated chalcopyrite, chunks of galena and purple coloured crystals of fluorite. This assemblage is seen only in the baryte bearing bodies of Naleswar village. Analytical results show Ba ranges from 41.89 to 58.39%. Tungsten G4 stage investigation for tungsten Gadchiroli Navgram 1:12500 75 - - - and associated mineralisation was area taken up in this area.
