Project Summary DHARGRAM STONE DEPOSIT AREA 15.78 Ha 1. INTRODUCTION Dhargram stone deposit of M/s Sukriti Pebbles is a partnership firm having six partners. Mine is located at Dhargram villagePurulia Distric of West Bengal. The area represents small hillocks of black stone trending NW to SE ranging from 225m to 245m above from MSL. The highest elevation i.e. 245m peak is situated from the north-west corner of lease boundary. The black stone is exposed on the upper part of the hillocks. But on the lower part, some area covers with soil. The general slope of the area is on the SE side. The mineral reserve of this area has been estimated to the tune of 3754453.99MT and the life of mine is estimated at 6.25 years. The mine is planned for a production capacity of 600000 MT/annum stone boulders during this plan period. The entire stone boulders will be taken to applicants own crusher and screening unit having approx 2000 TPD capacity at village Taladih at about 4 Km away on the north side of the area. After size reduction it will be send to the different consumer as per their requirement. The mining plan of Dhargram Stone deposit of M/s Sukriti Pebbles has been prepared under rules 5(5 (a)) of WBMMR,2002 involving 39.00(15.78Ha) acres of area in village Dhargram in Purulia District of West Bengal Mining plan was approved by Chief Mining officer, Govt. of West Bengal vide Memo. No-489/CMO dated 20.03.2015.. 2. LOCATION AND ACCESSIBILITY 2.1. Detail of the area Dhargram stone deposit Project is situated at a distance of 45 Km on the SE to S side of District headquarter Purulia. State Highway Birbhum-Balarampur (SH-4) is at a distance of about 10Km. The area is accessible by the road through NH-33 Ranchi-TATA by covering a distance of 33 Km. The nearest railway line TaTa – Bokaro via Purulia is about a distance of 45 Km from the applied area. State : West Bengal District : Purulia Police Station : Barabazar Mouza : Dhargram Lease Area : 39.00 Acres (15.78 Hectares) Ownershil/Occupancy Govt. vested land The area is recorded as non forest barren land. 1 2.2. Public road / Railway line The area is located at a distance of 45 Km on the SE to S side of District headquarter Purulia. State Highway Birbhum-Balarampur (SH-4) is at a distance of about 10Km. The area is accessible by the road through NH-33 Ranchi-TATA by covering a distance of 33 Km. The nearest railway line TaTa – Bokaro via Purulia is about a distance of 45 Km from the applied area. Dhargram Stone Deposit Project is situated Barabhum Rly. Station (34 kms). 2.3. Location The area falls under Survey of India Toposheet No. 73 J/5 and is bounded by the co-ordinates Latitude N 22059’28.44” to 22059’44.67” and Longitude E 86027’35.89” to 86027’58.93” 3. GEOLOGY 3.1 Regional Geology: Purulia embraces diverse groups of rock of various geological ages ranging from Achaean to recent. It is generally held, though not universal, that two ‘Shear Zones’ run through the district and in north of Purulia & the other to the south. Both these ‘Shear Zones’ trend east west over the lengths of 70/80 Km. or more. The northern ‘Shear Zones’ passes from Digardih, Jabarban, Belamu in the west to Kasipur, Gorangdih in the east through Jaipur, Chas More, Panrhidih, Malthol & Kushtanr. The southern ‘Shear Zones’ appears to be longer and more prominent than the northern one. It runs Barabazar-Beldih-Balarampur in the West via Khariduara, Kutni, Tamakhun, Thakurdungn to Khatra Gorabari Porapahar of Bankura district in the east. These two relatively minor ‘Shear Zones’ are believed to be developed sympathetically with the formation of the main Singhbhum ‘Shear Zones one’. However pre-Cambrian tract of Purulia district is about 100 Km north of Singhbhum ‘Shear Zones’ proper. The area represents small hillocks of Black stone trending NW to SE ranging from 225m to 245m above from Mean Sea Level. The highest elevation i.e. 245m peak is situated on the north-west corner of lease boundary. The Black stone rock exposed part of the area on the upper part of the hillocks. But on the lower part, some area covers with soil. The general slope of the area is on the south-east side. 3.2 STRATA CLASSIFICATION & STRATIGRAPHY: Relevant table showing stratigraphy follows: TENTATIVE STRATIGRAPHIC SUCCESSION OF THE AREA:- Quaternary Coarse to fine sand slit & clay, Lithomargic clay yellow clay, Calcareous modules & laterite. unconformity Upper Gondwana Sandstone (Supra-panchet) 2 unconformity Panchet Formation Sandstone & Shale Raingang formation Lower Gondwana Sand,shale & coal seams Damuda Group Barren measures formation Ironstone shale & ferruginous SST. unconformity Pegmatite & allied rocks Pegmatites,quarts & chertviens, GRANITE ROCK epidote- feldspar-quartz vein, aplites & quarts – magnetite veins. Precambrian Porphyroblastic granite – gneiss, biotite granite composite gneiss, Migmatites, granetiferous Granite- gneiss Meta-basics Amphibolites, meta nonite, Hornblende-schist. 4.0 Local geology: The geology of the Dhargram stone deposit follows the Regional stratigraphy of this region. The Black stone exposed throughout the area on the upper part of the hillocks. But on the base part, weather soil covers the Black stone body. The general trend of the deposition is along NW-SE to almost E-W. The general slope of the area is on the south-east side and dipping in north direction of dip amount about 80º. On the basis of geological field study, a geological map has been prepared with a contour interval of 5m showing all rock types. The local geological succession of rocks in the are as observed during field study is as below:- Wethered Soil/sand Black stone 5.0 Estimation of Minarets reserves and life of the mine. Minerals reserve has been estimated to the tune of 3754453.99 MT. Taking the maximum production target of 6, 00,000MT per year, the life of the mine is calculate which as follows. Mineable reserve of stone 3754453.99 MT Production capacity per year 6,00,000 MT Life of the mine(Years) 6.25 years 3 .
