During this plan of mining period, Mining will be carried out in five blocks named A1, B1, C1, D1, & E Need for the project and its importance to the country and region The enhancement of the production capacity of the mine is proposed to cater the bauxite requirement of all the Refractory plants located at Khambhaliya (Guj), Katni (MP) & Dalmiapuram (TN) of M/s Dalmia Refractories Ltd. The manufactured products of high alumina refractories and other related products etc. are mainly used in Cement, Steel, and Chemical plants. Mining industry plays an important role in economic sector in India. Bauxite mine plays an important role for major production of aluminum. The bauxite is also use in different sector according to their use in commercial application, like abrasive, cement, chemical, metallurgical, refractory, etc. 15

India is ranked 6 th in the world in terms of Bauxite Reserves. With the development of aluminium factories the domestic demand for bauxite has been increased in the country.

16 India is ranked 6 th in the world in terms of Bauxite Reserves. With the development of aluminium factories the domestic demand for bauxite has been increased in the country. Gujarat is rich in mineral like bauxite. Next to Orissa, Gujarat ranks second and Jharkhand third in Bauxite production in India. Gujarat produces about 15% of India s bauxite and occupies third position. Jamnagar, Kaina, Sabarkantha, Kachchh and Surat are the main bauxite-producing districts. The state is endowed with major and minor mineral resources. The region, where the project is situated, people are mostly dependent on agriculture and mineral resources. The developments of mining in the area provide direct and indirect employment opportunities, infrastructure development, communication and socio-economic infrastructure. DRL is also implementing various programs for betterment of the surrounding area. 2.5 Demand-Supply Gap The demand for bauxite is mainly requirement of aluminum, cement, chemical, metallurgical, refractory industries. Gujarat was the main supplier of abrasive and refractory grade bauxite. Alumina plants draw supplies mostly from their captive mines In , the consumption of bauxite was estimated as million tonnes as compared to million tonnes in the previous year. Alumina / Aluminium Industry was the principal consumer of bauxite and accounted for 91% consumption in followed by Cement (7%) and Calcination (1%). The production of bauxite in the country for was at 24,665 thousand tonnes which decreased by 12% as compared to the previous year. There were 157 reporting mines in as against 190 in the previous year. Besides, 7 mines have reported production of bauxite as associated mineral during the year. Odisha emerged as the leading producing State accounting for about 49% of the total production followed by Gujarat (24%), Jharkhand (9%), Chhattisgarh and Maharashtra (8% each). The remaining was produced by Madhya Pradesh, Goa, Karnataka and Tamil Nadu. (Source: Indian Minerals Year book 2017 (Part- III : Mineral Reviews) 56 th Edition BAUXITE) There is a gap between the demand and the supply of bauxite. The enhanced capacity of the project aims to fill the demand supply gap through optimum allocation and excavation of natural resources required to meet the demand effectively. 16

17 2.6 Imports v/s Indigenous Production This is an existing operational mine for supply of Refractory Grade material for captive consumption for manufacturing of High Alumina Refractories & other related products in the DRL s plants located at Khambhaliya (Guj), Katni (MP) & Dalmiapuram (TN). However, Non Refractory Grade Bauxite generated during mining is disposed off by way of sale in accordance with the lease terms imposed by the State Govt. of Gujarat. 2.7 Export Possibility No proposal for direct exports of the Bauxite. 2.8 Domestic / Export Markets Refractory Grade Bauxite from the mine will be used for captive consumption in all DRL s manufacturing plants while the balance Non Refractory grade bauxite is periodically disposed off by sale against specific clearance from the State Govt. Scientific blending is already in practice as per approved mining scheme for achieving better rate of economic production and for optimum utilization of marginal grade bauxite inferior to the specification. 2.9 Employment Generation (Direct and Indirect) due to the Project Direct At present 144 employees are working in the mine and additional 137 employment shall be generated after the expansion of the subject mine.

However, Non Refractory Grade Bauxite generated during mining is disposed off by way of sale in accordance with the lease terms imposed by the State Govt. of Gujarat. Scientific blending is already in practice for achieving better rate of economic production and optimum utilization of marginal grade bauxite inferior to the specification Salient Features of Mode of Working The Mine development and subsequent exploitation is undertaken as proposed in the modified approved Mine plan and PMCP. There are five working pits at present i.e. Block A1, B1, C1, D1 and E1. Method of mining will be semimechanized opencast mining method forming benches up to 1.5m (avg.) height in O.B and 3.0m (avg.) height in ore. The sides of the benches have slopes at a safe angle not more than 45 degree from horizontal.. The overburden removal is by both means i.e. manual and mechanical method. In case the overburden thickness is more resulting in large volume of overburden handling, the excavation is carried out with the help of JCB excavators. Otherwise manual overburden excavation is carried out. In addition to the manual drilling, shallow blast hole drilling is also carried out with jack hammer / hand drills operated by air compressors. Mining in hard and compact bauxite horizon is carried out manually with benches not exceeding 3 m in height and width of the bench being maintained correspondingly. The slope of the faces in hard and compact bauxite is not allowed to be more than 60 degree from horizontal. Number of benches is varying as per the topography of the area. The cleaning of broken muck pile of the bauxite from mining face graded manually based on physical appearance by chipping, sizing, sorting & stacked in mining face for movement in assigned place for further assessment. The scientific blending is already in practice as stated in the approved mining plan / scheme in details for achieving better Refractory Grade Production or improvement for economic aspect and optimum utilization of marginal grade bauxite inferior to the specification with a view to achieve conservation of mineral. The Over burden is generated concurrently and simultaneously backfilling is done in mined out area. Top soil is being used for plantation purpose and also spread on backfilled area for Reclamation and Rehabilitation of mined out areas. The backfilled area is properly levelled and reclaimed by plantation. There were three dumps out of which two dumps have been completely utilized for backfilling and remaining one dump shall be liquidated in due course time Drilling and Blasting The manual activities of mining are predominantly based on manual drilling. But, at the time of hard and compact formations the shallow blast hole is carried out by machine drilling with the help of Jack Hammer & operated by Air compressors. The mine is worked with shallow hole blasting with holes of average depth of around 0.75 meters but 21

22 never more than 1.5 meters. Generally ten blast holes in single row are placed 0.75 m apart, in both parallel and vertical axis to the mine face.. Various types of explosives such as ANFO, slurry, emulsion etc. will be used for blasting.

There will be no dump Transport There are separate roads for incoming and outgoing traffic from the pit to provide one-way traffic at a gradient of not more than 1:16. Four Wheeled Trolley attached to tractor is generally used for movement of minerals and overburden within the lease area. The mineral transported out of the lease hold is with the help of dumpers and 22

23 trucks on hired basis. The Refractory Grade bauxite is transported to company s manufacturing unit located at Khambhaliya (Guj), Katni (MP) & Dalmiapuram (TN) using hired trucks / dumpers on road, rail and sea Mineral Processing Operations (if any) No mineral processing operation is carried out. Scientific blending is already in practice as stated in the approved mining scheme / plans for achieving better rate of economic production and optimum utilization of marginal grade Bauxite inferior to the specification with a view to achieve conservation of mineral by Manual sizing, sorting & grading during the operation Production for the planned period The bauxite production for planned period is 3,00,755 TPA which is detailed below. Table 3-5: Production planned period Year Block Bauxite Plant (Refractory) Grade (tones) Non-Plant (Refractory) Grade (tones) Total (tones) A B C D E Total Along with the bauxite, about 8,800 TPA Topsoil & 2,22,080 TPA OB/waste will also be generated at peak production Life of Mine Left out mineable reserves is 6.41 million tonnes and proposed rate of production is 3,00,755 TPA (0.3 MTPA) hence life of mine is envisaged around 21 years. 3.6 Conceptual Mining Plan Mineral Exploration No Proposal, because complete exploration work was carried out Ultimate Pit Limit The conceptual mining limit has been derived on the basis of geological plan, geological sections slope of working faces & sequence of mine development. The ultimate pit limit shows the extent of the extraction from the mines Geological Sections showing in approved mining plan. To delineate mining limits covering all Mineable blocks a number of geological sections have been examined and the pit limit boundary have been drawn considering slope of working faces and sequence of mine development in all the blocks. The conceptual mining plan has been considered based on available Mineable reserves in all blocks. A conceptual mining limit (in section) has been drawn showing the ultimate pit limit. The Ultimate pit limit shall be over an area of Ha Ultimate Pit extent As per approved mining plan, during this mining period, Mining will be carried out in five blocks named A1, B1, C1, D1 & E1. The rate of ROM production will be 3,00,755 TPA. During this mining period the depth of excavation will be up to 7.0 m in A1 block, 13.0 m in B1 block, 9.0 m in C1 block, 9.0 m in D1 block & 14.0 m in E1 block by making systematic benches of 5.0 m maximum height in mineral. 23

At the end of life of mine, out of the total excavated area about Ha area shall be backfilled & reclaimed by plantation and remaining Ha area shall be converted into water reservoirs. The depth of water reservoir shall be from 7 m to 12 m Stacking of Mineral Rejects and disposal of Waste The modified plan envisages soil & overburden removal in the year as seen from the Table 3-7 below. It has been estimated that during the year phase of mine working, the overburden will have to be removed from the area covered by alluvium soil and weathered calcareous material. The alluvium area shall be removed in advance, prior to the commencement of the ROM production. The waste generated in past has been disposed off by means of backfilling and rehabilitated by plantation. Present back filled area is about Ha. OB material will be used for simultaneous backfilling and will be rehabilitated by plantation, hence there will be no dump at the site. An area of about 1.31 Ha is proposed to be backfilled during the Modified Mining plan period At the end of life of mine about Ha area shall be backfilled & reclaimed. The area program in the year for estimated in situ quantity of overburden is as follows: Table 3-7: Area to be back filled by Year Top Soil (Mt.) Over Burden (Mt.)

There are total seven non Plant (Refractory) Grade piles can be seen at mine site. The height of sub-grade bauxite mineral is varying from 4.0 m to 8.5 m whereas area covered is varying from 505 sq mts to sq. mts. The Piles are made in single bench with average height not exceeding 7.5 meters and slopes ranging around 35 degrees from horizontal on rocky base. Since these piles are temporary in nature the existing arrangement is considered adequate.

26 3.8 RESOURCE OPTIMIZATION/ RECYCLING AND REUSE ENVISAGED IN THE PROJECT, IF ANY, SHOULD BE BRIEFLY OUTLINED Top soil is being/will be used for plantation purpose and also spread on backfilled area for Reclamation and Rehabilitation of mined out areas. No mineral processing operation is carried out. The Over burden is generated concurrently and simultaneously backfilling is done in mined out area and the same practice shall be continued. Scientific blending is already in practice as stated in the approved mining scheme / plants for achieving better rate of economic production and optimum utilization of marginal grade Bauxite inferior to the specification with a view to achieve conservation of mineral by Manual sizing, sorting & grading during the operation. The on and average blending ratio of bauxite production from blocks A1, B1, C1, D1 & E1 will be 10%, 20%, 21%, 25% & 24% respectively. The sub-grade mineral called the non-plant (Refractory) Grade bauxite has a ready market for disposal. But due to the insistence of the State Government to incorporate extraneous clause in the lease deed restricting the disposal only after obtaining their specific permission each time results in accumulation of stocks at the pit head results in accumulation of stocks at the pit head of such material since the State Govt. takes considerable time in granting the permission. The sub-grade mineral bauxite (non Plant (Refractory) Grade) is being stacked on temporary basis and disposed off only after obtaining specific permission of State Govt. There are total seven non Plant (Refractory) Grade piles can be seen at mine site. The height of sub-grade bauxite mineral is varying from 4.0 m to 8.5 m whereas area covered is varying from 505 sq mts to sq. mts. The Piles are made in single bench with average height not exceeding 7.5 meters and slopes ranging around 35 degrees from horizontal on rocky base. Since these piles are temporary in nature the existing arrangement is considered adequate. 3.9 Availability of Water its Source and Energy/Power Requirement Water The Proposed Daily Requirement of Water at Mine Site: - 1. Water sprinkling : KLD 2. Plantation : KLD 3. Domestic & Drinking : KLD Total : KLD Source: Drinking water is purchased and transported by authorised water tankers on hired basis whereas rain water collected in mined out pits is used for plantation and dust suppression. In addition to this, if more water require for dust suppression other than accumulated rain water, will be sourced from authorised tankers Fuel/Power Requirement The mine is being/will be worked by semi-mechanized method. Electric connection has already been taken for office and other facilities. For HEMM operation during mining, it is envisaged that about 1 KLD of diesel will be required. About 3 lit/hr diesel will be used as fuel for running pump for dewatering in rainy season. 26

27 3.10 Quantity of Wastes to Be Generated (Liquid and Solid) And Scheme For Their Management/ Disposal Nature of Waste & Rate of yearly generation In the proposed mining plan period, soil and OB is likely to be generated. Soil will be used for plantation while OB will be used for backfilling. Quantity of Waste Quantity of Waste During the proposed plan period about 8800 MT of topsoil and MT of OB shall be generated at peak production Selection of Dumping Site and Disposal The subjected mine is an existing operational mine. The backfilling program, in fully exploited portion of the worked out pit, is a part of the reclamation program which is already in operational practice. The waste generated in past has been disposed off by means of backfilling and reclaimed by plantation. Present back filled area is about Ha. The OB generated during mining period will be backfilled in the mined out area in north part of the lease area. An area of about 1.31 Ha is proposed to be backfilled during the Modified Mining plan period There will be no fresh OB surface dumping within ML. As volume of voids is much more than material available for backfilling of entire mined out area up to original ground level will not possible. Therefore, at the end of the life of mine, Ha area will be backfilled and will be reclaimed by plantation. Remaining Ha of the excavated area will be used as water reservoir. There is no surface dump proposed at outside the ML area Liquid Waste Management Sewage: Domestic waste water will be disposed off in septic tank followed by soak pit at site. a) Regular monitoring of ground water level and quality shall be carried out in and around the mine lease by establishing a network of existing wells and constructing new piezometers during mining operations. The monitoring is being/shall be carried out four times in a year and data thus collected is sent to concerned authorities. b) Surface run off: - Garland Drains, if required shall be constructed for pit and dumps and, sump capacity shall be designed, keeping 50% safety margin over and above peak sudden rainfall and maximum discharge in the area and adjoining mine site. Sump capacity shall also provide for adequate retention period to allow proper settling of silt material. Sedimentation pits shall be constructed at the corner of the garland drain and desilted at regular interval. A water pump will be installed for dewatering the accumulated rain or surficial water from the excavated area of the mine during monsoon season. During monsoon season; the mine will be closed/sealed during the rains. Accumulated rainwater will be filtered during pumping process to pendent or suspend solids materials. Part of filtered water will be used for plantation & rest will be diverted into natural drainage. Mineral bauxite being non-toxic in nature, no harm is envisaged on surface water. There is no discharge of water or any other effluent from this mine and also no generation of any toxic or hazardous substance which may affect the quality of water in buffer zone of lease area. 27

28 4 SITE ANALYSIS 4.1 Connectivity Mine can be easily approachable by the local road/village road. The Mine is about 0.81 km by crow flight distance towards NNE of Village Virpur, while by Village road, which could best be described as cart track, the approach is two km long. Virpur is approachable by a combination of ill maintained paved road, gravel road and cart track through village Ran which is located about 1km north of the tar road connecting village limbdi with Dwarka. Limdi is located on the Devbhumi Dwarka- Okha state highway no. 29 and is about 35km from Khambhaliya. State Highway 29 is located ~12 km South direction of the lease area. Coastal Highway CH-6 is at distance of ~10 Km in south direction of lease. The nearest railway station is Bhatia which is located Okha-Devbhumi Dwarka-Rajkot-Virgaon broad gauge section of western railways and about 20 km from the site. The nearest sea port is Okha which is about 105km from Mewasa. 4.2 Land Form, Land Use and Land Ownership Entire lease area is designated as Government Waste land free from any type of Forest Land, habitation, Eco Sensitive Zone. As per the Survey carried out by Institute of Remote Sensing,Anna University,Chennai, Sq.m (about Ha) area at Northern boundary of ML is falling uin CRZ III Category which is already demarcated as non-mining zone. There is no habitation within the ML. The highest contour value in the lease area is m and lowest contour is of 6 m. The general slope of the area is towards northeast direction. There is no seasonal Nalla flowing through the lease area. There is no firm drainage pattern. 4.3 Topography Rugged topography was seen in the mine. The temporary benchmark has been shown on surface plan i.e m. Maximum elevation recorded in the mine is 29.52m, whereas the minimum elevation is observed 6.00m. (these m levels are based on the total station survey data with the reference of assumed base level i.e m). Trees are found in very less numbers in and near the mine. Dispersed some type of thorny bushes can be seen in accepting numbers. Human settlement are not present near the vicinity of the mine. 4.4 Geology Geology of Area The shallow bauxite deposit of Kalyanpur occurs in north-south trending laterite belt from Mota Asota to Lamba Village. The laterite forms almost a continuous horizon underlying Gaj beds and overlying Deccan Traps. The scattered bauxite pockets are encountered in the exposed as well as concealed laterite horizon. Deccan Trap covers almost entire eastern portion of the district over lain by a mantle of soil. Quartz / Calcite fill the geodes in Trap which is traversed by Dolerite dykes. Laterite belt occupies the periphery of the Trap. Tertiary formations commence with the Gaj Beds over lying the traps as well as laterite. Fossiliferous limestone of Gaj Beds spread out extensively in Kalyanpur Taluka whereas at other places it occurs in isolated patches. Fossils are conspicuously absent from Dwarka Beds developed near Dwarka and Bayt island. Milliolite limestone occurs all along the coast as well as in small island pockets. 28

Quaternary Tertiary Geology of lease area The surface geology indicates presence of alluvial and soil mostly in the peripheral low lying plan part of the leasehold. The undulating terrain within the leasehold predominantly contains lateritic / bauxitic exposures over lain with small pockets of the highly weathered calcareous material. Two pockets of the highly weathered calcareous material, one in the central part of the southern boundary of the major northern part of the leasehold and the other near the eastern boundary of the small south eastern part of the leasehold, are however noticeably larger in size. The highly weathered friable calcareous material consists of clay which is predominantly yellow in colour and frequently concretionary in nature. The lateritic and bauxite horizon red in colour when consisting chiefly of ferruginous material associated with bauxite and mottled red, pink and gray coloured clay. The mine section has been generalized as Soil, alluvium and clay: 8 10 meter Weathered calcareous rock: 3 4 meter Bauxite and Lateritic Zone: meter Laterite grading to lithomarge: Below Bauxite Material.

34 5 PLANNING BRIEF 5.1 Planning Concept (Type of industries, facilities, and transportation etc.) Town and Country Planning/ Development Authority Classification Type of Industry: Mining of Bauxite Present Proposal: For enhancement of bauxite production from 80,000 TPA to TPA in addition of removal of Topsoil 8,800 TPA & OB/waste 2,22,080 TPA with Total Excavation 5,31,635 TPA. Facilities: Mine office, rest shelter, Drinking water facility, store room, Weigh Bridge, canteen, toilet and lavatory. Transportation: Bauxite will be transported through trucks to the plants of DRL. 5.2 Population Projection This is an existing mine. Temporary influx of people will be there as the managerial and supervisory staff will generally be from outside the area. Suitable local people has been /will be appointed preferably in the mine. Hence project will not contribute significantly in the decadal population. 5.3 Landuse Planning (BREAKUP ALONG WITH GREEN BELT ETC.) Table 5-1: Land Use Pattern at site (in Ha) Heads Existing After Plan period Conceptual stage a) Pits & Quarries (Within) (Backfilling : Ha & water reservoir :60.65 Ha) b) Dumps of Waste & O.B c) Mineral Stack c) Infrastructure including of office, urinal, magazine& Mine Road etc d) Township (Colony & School) e) Others Barren land Crop land f) Undisturbed area affected under CRZ III Category/ Non Mining Zone Total occupied area At present about 8 ha area is under plantation. About 1500 No. of saplings per hectare is proposed to be planted within the existing plantation area to improve aesthetic beauty. Measures will be adopted to ensure survival & protection of plantation. At the end of the life of mine, about ha area shall be under plantation including backfilled area. 5.4 Assessment of Infrastructure Demand This is an existing Mine. There will be negligible additional impact as the existing infrastructure will be sufficient for the expansion project. Existing social and physical infrastructure are sufficient to cater to the requirement. The mine site is well connected to the nearest state highway. 34

Suitable local people has been /will be appointed in the mine. Temporary influx of people will be there as the managerial and supervisory staff will generally be from outside the area. 6.3 Social Infrastructure Detailed in Section Connectivity (Traffic and Transportation Road / Rail / Metro / Waterways) As per Section Drinking Water Management (source & supply of water) Detailed in Section and Section Sewerage System Toilet facility has been provided at site. The generated sewage is channelized to septic tank followed by soak pit. 6.7 Power Requirement and Supply / Source Discussed in Section Industrial Waste Management Discussed in Section Solid Waste Management Discussed in Section Rehabilitation and Resettlement (R& R) Plan Not applicable as this is an existing mine and no additional land purchase is involved. 36

37 6.11 Project Schedule and Cost Estimates LIKELY DATE OF START OF CONSTRUCTION AND LIKELY DATE OF COMPLETION (TIME SCHEDULE FOR THE PROJECT WILL BE GIVEN) The mine lease is working site of DRL however; DRL will start production at proposed rate only after obtaining necessary clearance from Central and State Government Estimated Project Cost ALONG WITH ANALYSIS IN TERMS OF ECONOMIC VIABILITY OF THE PROJECT Estimated cost of the proposed expansion would be around Rs lacs only. This cost includes the project expenditure towards the Bauxite mine. The mine has been sanctioned by the Government for captive consumption; hence the profitability factor does not arise at this stage. 37

38 7 ANALYSIS OF PROPOSAL Local labourers will be employed from the nearby villages as per this mine operation. Financial and Social Benefits with Special Emphasis on the Benefit to the Local People including Tribal Population, if any, in the Area Critical analysis of the existing socio-economic profile of the area vis-à-vis its scenario with proposed project activities identifies the following: Collectively mining (present in the Region since more than 5 decades) can however be considered a significant economic activity in the Region. Supporting infrastructure (essentially roads & power supply) is already in place. Consequently, the possibility of this project triggering significant ancillary developments seems unlikely. However, the proposed activities shall generate direct and indirect employment in the region due to the requirement of workers in supply auxiliary such as higher machinery service and Ore Transport service afford from the ancillary works, which would marginally improve the economic status of the people. About 137 employees shall be appointed in the mine after proposed expansion. Preference shall be given suitable local people. This will upgrade the economic status of the region and people living therein.
