Ltd., is situated in villages Sirohi and Lunghar under Ukhrul district of Manipur. The ML area is featured in the toposheet No. 83 K/8. The granted lease is bounded between ML Boundary Latitudes Longitudes A 25° 09’ 52.35’’ N 94°28’ 10.67’’ E B 25° 09’ 00.36’’ N 94°28’ 14.67’’ E C 25° 08’ 59.36’’ N 94°27’ 47.67’’ E D 25° 09’ 51.35’’ N 94°27’ 43.67’’ E The ML area is devoid of any forest land or agricultural land; entire land is categorised as unclassed Govt. land. The Geological Proved reserve of exposed ore bodies is estimated to be 1134 tonnes. The geological probable reserve of float ore zone is estimated to be 91674 tones. Therefore total demonstrated reserve (Proved and Probable reserve) is 92,808 tones. The total mineable reserves is 92,808 tones. The production capacity of the mine is 10531 tons per annum. Based on current exploration data, the life of the mine is 9 years. The operation of mine will be fully manual by opencast method of mining with an objective to produce 10531 (maximum) tones per annum. Dumper/ trippers will be utilized for shifting ore and overburden to respective sites. Drilling and blasting will be conducted to dislodge the OB and ore body. During plan period, 33552 m3 of mine overburden and inter-burden will be generated. During conceptual period, 37588 m3 of mine overburden and inter- burden will be generated. The waste dump site is selected on the south-west side of the ML area, which barren and spread over 2.0 ha. The height of the dump during proposed plan period will be 5m and overall slope of 28°. Total ML area is 132.781 ha and entire area is unclassed Govt. land. During the plan period 10.10 ha and during conceptual period 29.20 ha land will be used for various mining purpose. It is proposed that at the end of 5 year plan period 5.10 ha and 10.19 ha at the end of conceptual period will be degraded for quarry purpose. The mined out area will be reclaimed, once it is proved no ore will occur below UPL. In case ore occurs below UPL, mining will be continued till it is proved that no ore shall be continued. At the end of life mine, the broken up area will be reclaimed and rehabilitated. SIROHI –LUNGHAR CHROMITE MINES SRPL 1 The average water requirement is 6.5 KLD and peak demand is 10.25 KLD. Water will be sourced from ground water. About 48 miners are proposed to appointment. Apart from 19 numbers of personnel is also required for this mine. The safety zone around the ML area and dead end of the OB dump will be utilised for plantation. It is proposed to plant of 4.005 ha land and 6408 sapling in the Plan period. Project Cost is estimated to be 20 crores during Plan period. SIROHI –LUNGHAR CHROMITE MINES SRPL 2 2 INTRODUCTION OF THE PROJECT/ BACKGROUND INFORMATION 2.1 OVERVIEW M/s Sarvesh Refractory Private Limited (SRPL) was established in the year 1993. It has set up modern facilities of manufacturing for procurement of powder from mineral, ferrous and non-ferrous metals and its slag, processing, calcining, reducing, amalgamating, dressing, refining, composing all types of minerals and minerals rejects to make them marketable and usable as industrial raw materials. It has present manufacturing capacity of 69,500 tonnes per day. M/s Sarvesh Refractory Private Limited had applied for grant of Mining Lease for Chromite over 132.781 ha situated in village Shirohi-Lunghar in Ukhrul district of Manipur State. The State Government has issued approval vide letter No. 43/11/2006-Com & Ind dated 30/08/2007 with the prior approval of the Central Government vide letter No. 5/93/2006-MIV dated 10/08/2007, issued its previous approval, in favour of the M/s Sarvesh Refractory Private Limited under sub-section (1) of section 5 of the Mines and Minerals (Development and Regulation) Act, 1957 and rule made thereunder for grant of a mining lease. M/s Sarvesh Refractory Private Limited has completed the conditions specified under Govt. approval Letter no. 43/11/2006-Com & Ind dated 30/08/2007 and Ministry of Mines, Govt. of India order No. S.O 27 (E ) dated 4/1/2017 without submission of Environmental Clearance (EC). Thereafter, the Director of Trade, Commerce & Industries has issued a letter No. D(5)-65/IND/2005 (Pt) dated 4/8/2018 to M/s Sarvesh Refractory Private Limited for grant of Mining Lease. M/s Rourkela Minerals Company Private Limited has submitted the a Performance Security as specified in the letter no. No. D(5)-65/IND/2005 (Pt) dated 4/8/2018. M/s Sarvesh Refractory Private Limited has signed the Deed for Grant of Mining Lease from Director of Trade, Commerce & Industries, Government of Manipur on 23.02.2019. (Refer Annex-1 Deed for Grant of Mining Lease). 2.2 LOCATION The 132.781 ha mining lease is located in Shirohi-Lunghar village, in Ukhrul district of Manipur State and is featured in Topo-sheet No. 83 K/8. The coordinates of the ML is as follows (Refer Map Figure-1): ML Boundary Latitudes Longitudes A 25° 09’ 52.35’’ N 94°28’ 10.67’’ E B 25° 09’ 00.36’’ N 94°28’ 14.67’’ E C 25° 08’ 59.36’’ N 94°27’ 47.67’’ E D 25° 09’ 51.35’’ N 94°27’ 43.67’’ E SIROHI –LUNGHAR CHROMITE MINES SRPL 3 The ML area is approximately 103 km by road from Imphal. The nearest town is Ukhrul about 23 km from the ML area. The nearest railway station is Dimapur, is about 280 km the ML area. SIROHI –LUNGHAR CHROMITE MINES SRPL 4 2.3 Figure 1.1: Mine Location Map Toposheet SIROHI –LUNGHAR CHROMITE MINES SRPL 5 2.4 GEOLOGY AND RESERVE 2.4.1 Geology The major part of the area is covered with ultramafics of ophiolites suite comprising dunite, harzburgite, serpentinised harzburgite, pyroxinites and chromite. The litho units runs in north-south to north north-est- south-south west direction. Sporadic pots and pockets of massive nodular spotted and disseminated chromite ore present within the ultramafics. All the varieties of chromite ore occur together in the host rock of serpentinised harzburgites. The chromite occurrence in the area is in the form of pods and lenses being found in the horzburgites and dunites which have undergone various degree of serpentinisation. The podiform deposits within ultramafics area erratic in distribution pattern and their depth persistence is irregular but with sharp contact with host rocks. The chromite mineralization in the form of pods, pockets and lenses is confined to an area measuring 1000m long and 600 m wide in the phangari hill as exposed on the surface. Broadly, three different modes of occurances of ore found, as follows: Massive ore associated with harzburgite in shape of pods and angular blocks; Nodular ore; and Friable and disseminated ore. Massive ore are found in the mid slope and on the ridge of Phangrai in association with minor nodular and disseminated ore. Nodular and friable ore occurs on the top of the hill ridge as well as the mid slopes. The initial geological exploration study reveals that Hard Lumpy and Massive Ore (HLMO) trending NNE-SSW over a strike length of 100m close with an average width of 5-7 m. HLMO of different sizes with perfect orientation, indicates that the ore may continue for few meters in depth ward direction and similar patches can be traced out elsewhere within or outside the area.
