The mine lease is spread over villages: Tilkuda, Uskuda, Sareikala and Kurmitar Reserve Forest. Kurmitar iron ore mine is one of the old operating mines of OMC. The lease deed was executed on for a period of 20 years which expired on Application for further renewal of the lease for a period of 20 years w.e.f was made on for a lease area of ha. Application for 2 nd renewal of the lease for a further period of 20 years was made on stating that the second renewal application submitted by OMC on to be treated as second installment of the first renewal for a period of further 10 years from to Accordingly the 2 nd lease renewal application was for a period of 20 years from to The lease is under deemed renewal status. The Environment Clearance and the Stage-II Forestry Clearance for an area of ha of mine have been accorded by Ministry of Environment, Forests and Climate Change, Govt. of India (MoEFCC) vide letter no. J-11015/1080/2007-IA.II(M) dated & vide letter no /2000-FC(Vol-I) dated respectively. Consent to Operate has also been granted by the State Pollution Control Board, Odisha under the Air & Water (Prevent & Control of Pollution) Act, which is valid till The mining plan, for deemed renewal period, for a lease area of ha was approved on , vide letter No.BBS/SG/Fe&Mn/MP-272 dated which was valid till But due to nonavailability of Forest Clearance, the production as proposed in mining plan could not be met. So to comply the violation, a modification to the approved mining plan was prepared incorporating the achievements from to and modified proposals for the rest two years i.e. from to The said modified mining plan was approved by the Controller of Mines, IBM, Nagpur dated The scheme inside the mining plan was valid up to The scheme of mining for the period from to was approved on The modification to scheme of mining for the period from to was approved on 29 th November The validity of the scheme of mining is till Earlier the lease area of Kurmitar Iron Ore lease was ha, out of which ha area has been surrendered by OMC on and Final Mine Closure Plan (FMCP) for surrendered area of ha has been approved by IBM on Thus presently the lease area of Kurmitar Iron Ore Mine is ha. The mine is an open cast mine and comes under Category-A as per EIA notification 2006, Amendment Nov & April of the MoEFCC. It has three existing quarries (viz. Quarries 1, 2 & 6). The deposit is being worked by opencast mining with formation of benches by drilling and blasting. The present proposal envisages capacity expansion of existing opencast cast mine from present rated capacity of 2.4 Mt/yr to 6.0 Mt/yr with decrease in ML area from ha to ha. The existing quarries will be expanded and the number of benches shall increase. Drilling and blasting is being used for hard laminated & massive ore, whereas, soft ore is directly excavated by m 3 capacity hydraulic excavators. The proposed height of bench is 6 m with 15 m minimum working width. Width of bench has been planned to be reduced to 6 m at the ultimate stage near lease boundary. Bank slope has been considered as 70 o. Envisaged ultimate pit slope of the Kurmitar iron ore mines is 32 o. Haul road has been planned at a gradient of 1 in 16. Inter bench ramp width has been considered as 8 m. The ROM will be transported to crushing and screening plants for production of calibrated lump ore (+10 to -40mm) and fines (-10mm). The waste & subgrade material generated will be transported to respective Waste Dump and Subgrade Dump. The lumps and fines generated from the processing plants will be loaded by loader of m 3 capacity & transported through 20 t tippers/ 35 t dumpers to the respective stockyards., 2015 MECON LIMITED, All rights reserved Page 1 of 19

6 A 800 tph capacity stationary crushing and screening plant has been proposed. In addition to this, one existing 225 tph crushing and screening plant will also be maintained to meet the incidental break down and achieve the target. Moreover, a new mechanical evacuation system for fines has been planned to be commissioned. It has been decided to lay a two-line conveyor belt system each having 1000 tph capacity. The said conveying system shall be housed inside fully covered (by G.I sheet) structural steel galleries supported by steel trestles at suitable intervals. These trestles shall be supported by reinforced concrete (RCC) pedestals and foundation. The expected life of the mine is 25 years and a total of Mm 3 of wastes will be generated from entire Kurmitar iron ore mine upto conceptual stage. Present waste dump will be used for dumping the waste for initial 5 years. From year 2020 onwards waste generated from Kurmitar iron ore lease will be dumped partly in existing dump and balance waste will be backfilled in the proposed backfill areas viz. backfill 1, backfill 2, backfill 3 & backfill 4. The mine s rated capacity shall be 6.0 Mt/yr of iron ore at an anticipated stripping ratio of 6.75 t/m 3 with external dumping for the year of production in the existing dump area. The ore from Kurmitar mine will increase the supply of iron to India s domestic steel manufacturers. The project will also generate much needed employment. Majority of the people employed at the mine will be local residents. Economy of the area will get a boost and there will be overall growth of the region in terms of education, health, training and transport etc. The local people s standard of living is also expected to improve., 2015 MECON LIMITED, All rights reserved Page 2 of 19

10 2.2 BRIEF INFORMATION OF THE PROJECT Kurmitar Mine is an open cast iron ore mine located in the Barsuan block of Bonai sub-division of Sundargarh district of Odisha. The lease area is spread over ha, which comprises of Reserve forest and Protected Reserve forest. The lease deed has been executed on for a period of 20 years, which expired on Application for further renewal of the lease for a period of 20 years w.e.f was made on for a lease area of ha. Application for 2 nd renewal of the lease for a further period of 20 years was made on stating that the second renewal application submitted by OMC on to be treated as second installment of the first renewal for a period of further 10 years from to Accordingly the 2 nd lease renewal application was for a period of 20 years from to The lease is under deemed renewal status. The Environment Clearance of the mine has been accorded by MoEFCC in 2008 for production of 2.40 Mt/yr of iron ore. The Stage-II Forestry Clearance of the mine has been accorded for an area of ha by MoEFCC (FC Division) vide letter no /2000-FC(Vol-I) dated But, as per the recent guidelines of Hon ble Supreme Court, the mine has initiated actions for diversion of the entire forest land within the lease. Consent to operate have also been granted by the State Pollution Control Board, Odisha under the Air & Water (Prevent & Control of Pollution) Act, which is valid upto The mining plan for deemed renewal period for a lease area of ha was approved vide approval letter No.BBS/SG/Fe&Mn/MP-272 dated , which was valid up to Proposals were made in the mining plan for development of the quarries to fulfill the production target expecting forest clearance in the near future. But due to non-availability of Forest Clearance the production has been confined only to three quarries. To cater to the demand of steel industries and due to high market demand of iron ore the production in these three quarries have gone beyond the proposed target of approved mining plan. (However the total production from the mine had not exceeded 2.4 Mt/yr at any stage). So, a modification to the approved mining plan was prepared incorporating the achievements from to and modified proposals for the rest two years i.e. from to The said modified mining plan was approved by the Controller of Mines, IBM, Nagpur vide letter No. 314(30/2008-MCCM (CZ)/MP-14/1050 dated The scheme inside the mining plan was valid up to The scheme of mining for the period from to was approved vide approval letter No.314 (3/2009-MCCM (CZ)/MS-42 dated The modification to scheme of mining for the period from to was approved vide approval letter No.314 (3/2010-MCCM(CZ)/MS- 30/16 dated 29th November The validity of the scheme of mining is up to Presently the lease area of Kurmitar ore lease is ha. Modification to the approved mining plan due to change in the lease area from ha to present lease area of 651 ha has been approved by IBM, Bhubaneswar vide letter no. MMP/FM/02-ORI/BHU/ dated It is proposed to enhance the rated capacity of mine from 2.4 Mt/yr to 6.0 Mt/yr of iron ore with reduction in lease area (to ha from ha). The expanded mine will produce calibrated lump ore (+10 to -40mm) and fines (-10mm) for its dispatch to various sponge iron/steel plants. The ore s Fe content is expected to be 63-64%. Peak water requirement at Kurmitar Iron Ore Mine for domestic and industrial use are 25 m 3 /day and 175 m 3 /day, respectively. Average water requirement at Kurmitar Iron Ore Mine for domestic and industrial use are 20m 3 /day and 114m 3 /day respectively. The water is drawn from surface stream (141m 3 /day), borewell (25m 3 /day) and by recycling effluents (32m 3 /day)., 2015 MECON LIMITED, All rights reserved Page 6 of 19

11 A Safety Zone has been maintained all along the lease boundary as the Green Belt. 2.3 NEED FOR THE PROJECT AND ITS IMPORTANCE TO THE COUNTRY OR REGION : Iron ore is the key input for the iron and steel industry. Odisha is one of the major centres for manufacture of iron and steel. Several industries have come up in the state for the manufacture of iron and steel due to the easy availability of iron ore in the state. At the present rate, OMC is producing about 10 % of total iron ore production of the State. Proposed capacity expansion of Kurmitar Mine will have the following benefits: Increase the supply of iron for India s domestic steel producers, especially those in Odisha. In addition it will add to revenue generation of the District / State. The mine will generate additional employment, both direct and indirect which will lead to economic growth. OMC shall provide, school buildings, bus shelters, medical facilities and other amenities to local villages under the company s community development programme. The increased Iron ore production will boost the economy. Thereby providing growth and development to the country. 2.4 DEMAND AND SUPPLY GAP : India s domestic steel production capacity is ~83 Mt/yr of which 41 Mt/yr is produced by integrated steel plants and ~18 Mt/yr is produced through the DRI-EAF route. Since it takes ~1.6 t of iron ore to produce 1 t of steel, India s demand for iron ore is ~94.4 Mt/yr. India is one of the major producers and exporters of high grade iron ore. In , India s iron ore production was Mt. The major iron ore producing states are Odisha, Jharkhand, Chhattisgarh, Karnataka and Goa. India is world s 3rd largest iron ore exporter after Australia and Brazil. India s iron ore exports were Mt (~9.95%) in All major steel producers in India are implementing their growth plans to enhance hot metal production capacity. The iron ore requirement is expected to increase to about 206 Mt/yr by and 500 Mt/yr by In order to meet enhanced requirement of iron ore, all iron ore producers are taking necessary action to expand their existing mines. Iron ore production capacity will be enhanced to meet the expanded requirement in the next 3-4 years time. 2.5 IMPORT VS INDIGENOUS PRODUCTION : India produces a surplus of iron ore. In , India s iron ore production was Mt of which Mt (i.e. about 9.95%) was exported. 2.6 EXPORT POSSIBILITIES : Iron ore produced from this project will be exclusively consumed in the domestic steel industry. There is no proposal for export of iron ore from this project. 2.7 DOMESTIC / EXPORT MARKET: The iron ore are used in the iron & steel industry. They are basic raw materials required for manufacturing of iron and steel. India is one of the major producers of iron ore, most of which is consumed domestically. A minor proportion (~13.5% in ) is exported., 2015 MECON LIMITED, All rights reserved Page 7 of 19

12 2.8 EMPLOYMENT GENERATION: Presently Kurmitar mine employ 110 persons. The expanded mine shall employ a total of 412 persons comprising of 27 executives and 385 supervisors, office staff and workers. Most of the unskilled and semiskilled workers will be local persons. The officers, supervisors and rest of the workers will be housed in OMC s townships, located outside the lease in the Khandadhar village. 3.0 PROJECT DESCRIPTION It has been planned to enhance the production from 2.4 Mt/yr to 6.0 Mt/yr of the existing iron ore mining project with reduction in mine lease area. The project also envisages setting up another 800 t/hr stationary crushing and screening plant commensurate with the increased ROM production and installation of new mechanical evacuation system for fines. It has been decided to install a two- line conveyor belt system of 1000tph capacity (each line). The length of the conveyor belt will be approximately 17 Km. 3.1 TYPE OF PROJECT INCLUDING INTERLINKED AND INTER-DEPENDENT PROJECT The proposed project falls under Category A, as per EIA notification 2006, Amendment Nov & April-2011 of the Ministry of Environment, Forest and Climate Change, New Delhi. 3.2 LOCATION: Kurmitar Mining Lease area is located in villages Tilkuda, Uskuda, Sareikala & Kurmitar Reserve forest in Barsuan block & Bonai sub-division of Sundargarh district of Odisha. The mining lease area falls under Toposheet No. 73 G/1 & G/2 between latitude N & longitude 'E. The location of project is shown in Drg. No. MEC/Q77B/11/S2/T1 3.3 DETAILS OF ALTERNATE SITE: Since the proposed project envisages capacity expansion of an existing mine, possibility of alternate site is out of question. 3.4 SIZE AND MAGNITUDE OF OPERATION: The mine is under operation with the rated capacity of 2.4 Mt/yr. The lease area is ha. It is proposed to increase the ROM production to 6.0 Mt/yr. The rated capacity will be attained in the --th year of operation. As mentioned above additional crushing and screening facilities and material handling facilities will be installed commensurate with the increased ROM production. 3.5 MINE DESCRIPTION Geology: Regional Geology: OMC Ltd. s Kurmitar Iron ore deposit forms a part of the huge iron ore deposits of Jharkhand Odisha region. Eastern India is part of the volcano-sedimentary basins containing iron and to some extent manganese deposits of Precambrian age. Most of these banded iron-formation horizons belong to the oxide facies banded iron-formations but silicate facies banded iron-formations are also locally developed., 2015 MECON LIMITED, All rights reserved Page 8 of 19

13 The Precambrian iron ore of Singhbhum North Odisha region of eastern India occurs as part of the horse-shoe shaped broad synclinorium known as Iron Ore Group (IOG) of rocks that host most important iron ore deposits of India. The horse-shoe shaped iron ore deposits form a northerly plunging synclinorium. The iron ore deposits of economic importance occur in close association with BIF in Kumritar mining areas. The chemical and mineralogical variations between banded iron formations and high-grade massive including blue dust varieties from this region and the implications for their origin from BIF to iron ore still remain unresolved. Controversies about the origin of banded hematite and high-grade ores appear largely due to the mono-mineralic composition of the ores. The succession of rocks in the region is as follows. Upper Shale Banded Iron Formation (BIF) Lower Shale Volcanics Lithology The rock types encountered in the leasehold area are as follows:- Soil/ (Shaly)Laterite/ Ferrugenous Shale Ferrugenous Shale / LIO/ BHJ/BHQ/ Iron Ore Floats HLO/ HMO in undigested BHJ/BHQ SLO/ Blue Dust in undigested BHJ/BHQ BHJ/BHQ Tuffaceous Shale/ BHS/ Variegated Shale Basaltic Volcanics Soil & Shaly laterite : A part of the lease on western side close to the boundary & Northern part of the lease is covered by soil whereas, the hill ridges extending from the central part of the ML to eastern and southern parts are capped with shaly laterite. It forms the upper horizon of the succession. Laterite in this zone mostly bauxitized with enriched alumina forms the underlying shale and termed as shaly laterite. Top soil and laterite/ shaly laterite seem to be derived from underlying ferruginous shale and iron ore bearing rocks. Ferruginous shale : The upper shale in this zone is enriched with iron content. It is cherry brown in colour. Ferruginous shale may be considered as an indication of subsurface mineralization. It is mostly found in the vicinity of lease pillar No-48, near the southern boundary and in the central of the ML in the neighbourhood of Tanki Pit. Iron ore bearing rocks : Iron ore is associated with the following litho units and covers about 65-70% area. The rocks bearing iron ore are of various types are as follows: Iron ore floats: Iron ore float zone is found in the foot of the mineralized hillock of Quarry-2. The surface outcrops of such litho unit is very meager. Lateritic Iron Ore: Lateritic iron ore in the ML is the lateritised product of hard/ soft laminated iron ore. Thus, the same structures as found in the parent rocks could also be seen in this rock types. It is mostly in the NW quadrant of the ML area having a moderate dip towards north to NW direction. The thickness of LIO varies from 1m to m with an average thickness of 8.40 m. Soft Laminated Ore (SLO): It is found in most of the quarries. It is overlain by ferruginous shale, laterite/soil and iron ore float. Considerable thickness of SLO has been encountered in the boreholes drilled in the area. The thickness of such iron ore varies from 2 m to m., 2015 MECON LIMITED, All rights reserved Page 9 of 19

14 SLO is frequently associated with blue dust. SLO is of platy & biscuity in nature and can be classified in to mm size range invariably. Hard Massive Ore (HMO)/Hard Laminated Ore (HLO): Hard Massive Ore (HMO) and Hard Laminated ore (HLO) is hardly exposed in the ML area except in Qry-2 and are very meager when compared to the total ML area and to other types of ore. The exposure of this kind of ore is gradually diminishing day by day as the mining activity of such ore continues. HMO in the ML area is highly jointed and has moderate dip towards north-west direction. Two smaller insitu HLO patches are found within the Laterised HLO exposures in the NW quadrant of the ML. the HLO blocks have moderate dip towards the directions of north. Thickness of HLO/HMO varies from 3.80 m to BHJ/ BHQ: Though there is a continuous basement of BHJ/BHQ in BIF as ascertained from borehole inputs, their occurrence on the surface is not continuous and localized in several undigested smaller patches. A major portion of the mineralized block mostly in the western half (within the SLO exposures in Tanki Pit and Qry-2) is exposed with BHJ. Here, BHJ is highly jointed and traversed by secondary silica vein. Exposed BHJ patches show NW to Northerly dipping to a moderate magnitude. Banded Shale: This kind of shale is mapped in the southern faces of the Qry-2 and is mostly light green or brown in colour and hard in nature. Otherwise such litho unit is explored under the iron ore strata during borehole drilling and is a clear indication to devoid of mineralization in further depths. The light brown or light pinkish banded shale are sometimes found tuffaceous and named accordingly. The underlying basaltic volcanic might have generated metamorphic aureole on the overlying banded shale in its thermal zone to make it happen. It is softer and felt soapy in nature. Variegated shale: Variegated shale is a form the lower shale of variety in colour. It is the major exposure of the ML. Talkish Banded shale: This is white coloured lower shale with distinct lamina, mostly explored after BIF in depth. This shows similar character as of BHS. But, it is softer and felt soapy in comparison. Basaltic Volcanics: It is only exposed in the nala cuttings as mapped in the Sareikela and in the Uskuda villages. It is intersected after the banded shale in some boreholes. It is fine grained, greenish, siliceous and fracture rock without amygdoils. Fracture planes are conchoidal to subconchoidal. Though, the physical characteristics of this litho unit resemble to that of BHS (Banded Hard Shale) but its distinguished fracture and hardness makes it identified undoubtedly. Some of the core samples & exposures showed laths of feldspars indicating porphyroblastic texture. Local Geology Kumritar area belongs to Singhbhum Odisha Iron Ore Craton (SOIOC) contains vast deposits of iron ore known as iron ore group (IOG) (Saha 1994). The Precambrian IOG largely contains BIF in addition to the other volcano-sedimentary rocks (~ Ga, Sarkar et al 1969), forming a significant portion of the Singhbhum North Odisha Craton of eastern Indian shield (Saha et al 1984). The IOG in addition to BIF also contains other rock units like two generations of shale, tuffs that underlie or are inter-layered with BIF. High-grade hematite ore is concentrated in tabular stratabound bodies hosted by the BIF. Several economically significant ore bodies are located in the Kumritar deposits. Since multiple generations of shale occur rhythmically as markers within the IOG, the possibility of iron ore below the BHJ cannot be ruled out. The area forms a major part of the synclinal closure. The various structural imprints observed and recorded are in the BHJ and laminated ore. Very tight folding is very common in BHJ always, 2015 MECON LIMITED, All rights reserved Page 10 of 19

15 plunging N 100 E at angle varying from 100 to 700. The Nala sections clearly indicate the reversal of plunge and at places tilting towards east. M type of folds at the trough portion is clearly marked. The above facts clearly indicate an interference pattern of multiphase deformational episode. The primary structures such as bedding, pinch and swell are clearly seen in BHJ. The pent structures are very common in the area. Joints of three sets facilitated the BHJ to break in to blocks. The fractures are numerous and filled by secondary silica. The structural features are also very clear in SLO. Mostly tight folding plunging towards North is clear in Qry-2. The contact of HMO/HLO with underlying shale indicates a synformal structure. The formation in the southern part of the Quarry-2 dips at towards North, eastern part plunges towards NW at 10 0 and Northern part dipping at towards south as the three sides of the Quarry-2 is exposed. The hard massive ore is highly jointed and breaks into blocks of rhombohedra shape. Three sets of joints are clearly observed. The fractures are devoid of any fillings. SLO exposed in the Tanki Pit and other places exhibit east-west strike with moderate dip of 45 0 to 50 0 towards north. A major fault runs in east west direction.

17 anticipated stripping ratio of 6.75 t/m 3. The wastes generated from the mine will be partly dumped in external dumps & partly backfilled in the voids created during mining. Material containing 45-55% Fe has been considered as sub-grade. A total of Mt of sub-grade will be generated up to conceptual stage. Silica & alumina content in the sub-grade generated during mining will be too high making it unsuitable for steel making. However, around 5% of subgrade generated during the scheme period can be blended with high grade ore which will produce a blend containing 62% Fe, 2.91% SiO 2 & 3.71% Al 2O 3. It is proposed to beneficiate and utilize the subgrade ore depending upon the results of testing from a reputed testing agency. However, it has been planned to stack sub-grade material in separate dumps. The height & width of individual terraces has been considered as 10 m with a bank slope angle of A part of the mined out pit will be backfilled in the ultimate stage with the mine wastes where nonpersistence of ore has been proved. The quarry area will be fenced to prevent any inadvertent movement of persons into the area. Remaining mined-out benches will be afforested. When mineral reserves are exhausted, the mine shall be closed down in accordance with the approved mine closure plan. All waste dumps will be stabilized and biologically reclaimed. Some of the other infrastructure will be dismantled.
