Mine lease has been proposed in favor of M/s Minerals & Mineral Corporation (LOI has attached as Annexure-I). The proposed rate of production is 75000 TPA of Bauxite. The lease area comprises of private waste land and forest land. The estimated project cost is Rs. 35 crores. The expected life of mine is 70.82 years. 2.2 Brief Information about the Project The project has been proposed for mining of 75000 TPA of Bauxite by opencast method. The mine lease area is 58.6793 ha. The expected life of the mine is 70.82 years. Water requirement for the proposed project for drinking use, dust suppression and other use will be 2.36 KLD, which will be taken from nearby source. 2.3 Need for the Project and Its Importance to the Country or Region Bauxite is extremely important economically due to the very widespread use of aluminium. It is the most common light weight metal in use resources of bauxite in the country as on 1.4.2010, as per UNFC system are placed at 3,480 million tones. By grades about 84% resources are of metallurgical grade. The Bauxite produced in the mining lease falls under two categories i.e. High Grade and Low Grade. High grade bauxite is used in captive plant situated at Porbandar. The low 2 grade bauxite is used in the manufacture of cement and which is exported to Middle East countries is called low grade bauxite. 2.4 Demands-Supply Gap In 2010-11, reported consumption of bauxite in India was 11.77 million tones as compared to 12.23 million tonnes in the previous year. Alumina/ aluminium industry was the principal consumer of bauxite, accounting for 91% consumption in 2010-11 followed by cement (7.5%) and refraction (1%). 2.5 Imports vs. Indigenous Production In 2010-11, imports of bauxite increased to 63,584 tonnes from 54,345 tonnes in the previous year. Imports were mostly from china. Exports of bauxite decreased substantially to 119 thousand tonnes in 2010 - 11 from 476 thousand tonnes in 2009-10. Exports were mainly to Kuwait (42%), Qatar (17%), Oman (14%) and Nepal (9%). As per the report of the working Group for 12th five year Plan, the abundance of bauxite resources in Eastern Ghat regions of Orrissa and Andhra Pradesh are likely to be the hubs for bauxite mines activities in future. The working Group has recommended that the large deposits of these areas can be required for the Greenfield alumina refineries. Additional bauxite resources are required for the brownfield expansion of the existing alumina refineries. 2.6 Export Possibility The lessee does not export directly. The lessee will sell the non-plant grade bauxite to local buyers who export the same. 2.7 Domestic/ Export Markets Domestic Market The Nandana Bauxite mine is supplier of bauxite to various major industries of the region. Export Market There will be no direct export done by the proponent; bauxite will be sold to the local buyers who export it. 2.8 Employment Generation The proposed mining activity will provide employment to about 32 workers. The workers will be hired mostly from the nearby villages. 3.0 PROJECT DESCRIPTION 3.1 Type of Project Including Interlinked and Interdependent Projects, If Any. The mine is over an area of 58.6793 ha. The proposed production is 75000 TPA. This is an independent mining project and there are no interlinked projects involved. 3 The project falls under Category “A” Project or activity 1(a) as per EIA Notifications 2006, 2009, 2011 and 2013 4 3.2 Location The mining lease area is located at Survey No: 529(P) Village- Nandana, Taluka - Kalyanpur, District- Jamnagar, and State- Gujarat. The mining lease area falls in G.T sheet No. 41F8 Latitude : 22°09’04.4” N Longitude : 69°16’48.7” E Project Area Fig 1: Location Map of proposed Project site 5 3.3 Details of Alternate Sites Mining is site specific so no alternative site is proposed. 3.4 Size or magnitude of operation The mining lease has been granted over an area of 58.6793 ha. During five year total production of Bauxite shall be approximately 75,000 TPA. The average number of working days in the year would be 300. Regional Geology The area around Kenedy, Nandana, Mota Asota, Kenedy, Ran village exposes bauxite as segregated pocket within laterite or horizontal bedded bauxite deposit with in laterite or altered clay. The other rock type exposed in the region are trap rocks, limestone and lithomergic clays. The limestone belonging to Gaj beds series is overlying the laterites. The sequence of formation ranges from early Eocene to recent in age. The generalized stratigraphic sequence of the region is given below: - Sequence Age Sand dunes, Ran clays and aluminum Sub Recent to recent Gaj Beds Agrillacems limestone Calcareous clay Concretionary limestone Lower Miocene Calcareous grit conglomerate ---------------------------------------Unconformity--------------------------------------------------- Laterite with Bauxite Upper Eocene Pockets Supra Trappeans (Ochers Lithomerg purplebrown clay) Deacon trap Lower Eocene to late cretaceous The bauxite deposits of Kalyanpur Taluka, Jamnagar District, and Gujarat are associated with a narrow belt of laterite extending from Mota Asota village near Gulf of Kutch in north to Gandhvi village near Arabiansea coast on South. The laterites belt is about 7 km wide between Kenedy and Habardi village and is less than 1 km wide near Ran, Hadmatiya and Lamba village. On the west of this belt the laterites overlain by younger, Tertiary rocks and to the east they are underlain by the Deccan traps. The laterite-bauxite-clay sequence rests over Deccan traps. The laterite is distributed almost as a continuous zone between Gajbeds and underlying Deccantraps. The Gajbeds which overlain the laterites bauxite succession in the belt and 6 are mostly sub- horizontal in the disposition. They comprises or yellow colored argillaceous fragmentary limestone. Local Geology:- The entire lease area is covered with soil. Bauxite is present below thin cover of soil. Thickness of soil cover is 1.00m. Bauxite is exposed in the pit. In general thickness of bauxite is 4.00m. Recovery of high grade bauxite is about 10% of production; low grade (Al2O3 upto 30%) is 90% of production. Recovery percentages of bauxite are 90% of ROM based on the result excavation done so far in the area. Stratigraphic sequence found in the area can be summarized as under: Formation Thickness in Meter Topsoil 1.00 M Bauxite 5.00 M Lithomergic Clay - The topographical/Surface/Geological plan of the lease area has been prepared on the scale 1: 1000 with contour interval of 1Mt. 3.5 Project description with process details 3.5.1 Method of Mining The thickness of bauxite zone is 4.00 to 5.00m.The method of mining is almost the same as followed in other nearby bauxite mines i.e.
