GSI Apatite Purulia Around Lanka-1:12500 - 8 348.15 - Prospecting stage investigation (G-3) Parbahal areas for apatite and associated minerals in the apatite-magnetite rocks was carried out to assess the resources of apatite and associated REE-RM. The investigation was carried out involving drilling, PT and sampling. The study area exposes rocks of Chhotanagpur Gneissic Complex. A total of 384.15 m of drilling has been carried out in eight boreholes. Out of this only one borehole intersected lm thick mineralised zone between 12 m and 13 m depth. Coal Bardhaman Kamalpur block,1:10000 4 2 1303.35 - Promotional exploration under G-2 stage was initiated with the objectives Coalfield to establish the development pattern and structural disposition of Raniganj seams under Panchet cover, strike continuity of coal horizons intersected in adjacent Bishtupur-Dandeshwar block, resource potentiality and preliminary assessment of CBM potentiality of the area. A total of 1303.35 m was drilled in two boreholes RKP-1 and RKP-2 and 1303 m was geophysically logged. Thin coal seams of Raniganj Formation varying in thickness from 1 m to 1.7 m were intersected between 458 m to 646.4 m depth. The item was abandoned prematurely on 11.01.2014 due to overlapping with CBM leasehold area.

-do- Gaurangapur- 1:25000 - 2 833.1 - Promotional exploration (G-4 stage), Bankati block, outside FSP programme, was initiated Raniganj with the objectives to establish eastward Coalfield continuity of the regional coal seams of Raniganj Formation, already established in the Bishtupur-Dandeswar Sector and to demarcate suitable blocks for follow up regional exploration for coal under G2 Stage in the eastern part of . A total of 833.1 m was drilled in two boreholes RGB-1 and RGB-2. Seven thin coal seams/ bands with thickness varying from 0.5 m to 1.78 m were intersected between 275.35 m and 316 m depths in borehole RGB-1, whereas nine thin coal seams/ bands with thickness varying from 0.40m to 1.8 m were intersected between 249.05m and 417.17 m depth in borehole RGB-2. Needle Shale of Talchir Formation, Ajoy River section, Raniganj C.F. has been noted. Investigation is under progress. (Contd.)

Coal Birbhum Gazipur West 1:10000 6 3 1325.3 - Regional exploration under G-2 stage block, continued to examine the extent of Birbhum coal-bearing and other Coalfield Gondwana formations below the Tertiary and Rajmahal Trap cover and to appraise the coal and lignite seam development, if any. A total of 1325.3 m drilling was done in three boreholes BGZW- 2 to 4 and 556.6 m geophysical logging. Three regional coal seams, zones IV, III and II of Barakar Formation with cumulative thickness 4.82 m, 13.12 m and 1.91 m respectively were intersected in between 599.43 m and 720.57 m depth. Tests for baseline data generation for CBM were conducted. Investigation is under progress.

A total of 2142.1 m Coalfield drilling was done in five boreholes BHK-4 to 8 and 1481 m geophysically logged. Thin seams/bands in-between the depths of 392.06 m and 471.94 m with a maximum thickness of 0.97m was intersected in one borehole. Tests for baseline data generation for CBM were conducted. Investigation was closed on 30.03.2013.

-do- Djhara sector, 1:10000 6 1 336.1 - Regional exploration under G-4 stage south of Gazipur has been initiated to establish (west) block and continuity of coal-bearing Barakar east of Heruka Formation below the cover of Tertiary sector, Birbhum sedimentaries, to examine the Coalfield development pattern of coal and lignite seams and generation of baseline data related to CBM. 336.1 m has been drilled in this sector in borehole BDJ- 1. Investigation is under progress. Columnar joint within Rajmahal Trap is one of the notable features in Birbhum coalfield. Lignite Birbhum Krishnanagar 1:25000 40 4 179.8 - Preliminary exploration under G-4 area stage by scout drilling was initiated for assessing the resource potentiality of lignite within Tertiary sediments and to delineate stratigraphy and structural framework of the area. Exploration in Krishnanagar area does not yield any lignite seam although very thin coal bands of a maximum thickness 0.45 m were intersected in between the depths

of 14.9 and 26.9 m with a total drilling of 179.8 m in four boreholes RKN 1 to 4. Investigation was closed. Lignite Barddhaman Adharsuli -- 4 740.9 - Promotional exploration under G-4 sector stage continued to search for the development of lignite within Tertiary sediments and to establish resource potentiality. Adharshuli Block was taken up based on sporadic intersection of lignite in earlier explored blocks in the surrounding area. Total of 740.9 m has been drilled in four boreholes RAS 6 to 9. However, no lignite seam has been intersected. Due to non-availability of lignite seam and overlapping with CBM leasehold area, the item was prematurely closed. PGE Purulia Bagalia- 1:12500 100 8 348.15 77 Reconnaissance stage investigation Sonaijuri- (G-4) was carried out to search for Ni, Kashipur- Cr & PGE group of elements in mafic- Gopalpur ultramafic rocks and to understand its sector relation with surrounding CGC rocks. The work components include 100 km2 of LSM (1:12500) supplemented by a quantum of 5 cu. m. of PT and collection of samples. The area exposes rocks of Chhotanagpur Gneissic complex (CGC) and is characterised by migmatites, streaky biotite granite gneiss, porphyroclastic granite gneiss, biotite-quartz diorite(?) with enclaves of unclassified metamorphites. The unclassified metamorphites comprise of amphibolite, pyroxene granulite and calc-silicate rocks. Analytical results of 08 bed rock samples of mafic/ ultramafic(?) rocks show Ni value ranging from 51-632 ppm & Cr value from 110-1821 ppm and 05 petrochemical samples show Ni value from 455-1033 ppm & Cr value from 1208-2009 ppm. One BRS from Karunmandi reported Pd value of 320 ppb and Pt value of 75 ppb. Other samples recorded Pd values in the range of < 5 ppb to 20 ppb while Pt values are in the range of < 10 ppb to 68 ppb. Ore microscopic studies indicate presence of nickel sulphide phase (pentlandite as confirmed also by EPMA/Raman Spectroscopy studies), chalcopyrite, pyrrhotite and magnetite in the mafic/ultramafic(?) rocks of Asanbani area. Few scattered grains of silver were also observed.
