BRIEF SUMMARY The mining lease area applied for mining lease for mining of Quartz and Semi- precious stone over 23.104 ha.in village Dadarpalli under Biramitrapur subdivision of Subarnpur district Odisha in the name of M/s Jay Jagannath Multi Mineral Pvt. Ltd. on. 08.11.2007. The Terms and Condition letter for Grant of Lease was issued by Department of Steel and Mines Govt. of Odisha on 15. 10.2014. On receipt of Acceptance from Applicant the Grant order has been issued by Department of Steel and Mines Govt. of Odisha dated 21.10.2014 for 20 years. The mining plan was prepared and got its approval from Directorate of Geology, Govt. of Odisha on 07.08.2015 The lease area was granted for Quartz and Semi precious stone, but only 400 gm non gem beryl found during prospecting. So only quartz is to be mines from the lease area. The Mining lease area is situated in village Dadarpalli, Tehsil – Biramitrapur, District-Subarnapur, Odisha. It forms a part of Survey of India Toposheet no. 73 C/4 on a scale of 1:50,000 And bounded by the latitudes 21O01’10'49” (21O01’15'3” ) to 21O01’28.4” (21O01'34.9”)N and longitudes 84O02’18” (84O02’25.7”) to 84O02’46.47” (84O02'52.2”)E The area is approachable from Amarpalli (03 km). The village road connecting Amarpalli and Dadarpalli passes through the area. Well connected to State Highway -???. At a distance of about 3km Connecting Biramitrapur to Rairakhol The nearest rail head is Charmal. The Reservoir Thenga exist at a distance of 4 kms from the lease area in the North West direction. The applied ML area is situated in a plain to undulated terrain with some isolated mound with rock exposures. The general gradient of the area is from east to west The elevation of the area varies from 144 m to 160 m AMSL. One dry seasonal nala flows in the area from east to west control the drainage of lease area. Purunapani Nala control the Drainage of the area which is flows out side the lease area in the western direction of the lease. Out of the 23.104 Ha mining lease area, Patita category of land (reserved for village forest) comprises 18.243 Ha, 3.938 ha. of agriculture land and 0.923 Ha of waste land. No forest land involved in the mining lease area. The area is in the sub-tropical climate zone with variation of temperature from 100C in the month of December to 480C in the month of May. The rainfall of the area is around 1100 mm in an average as recorded at Birmaharajpur. June to September receives maximum rainfall. Predominant wind direction SW/S/SE. Summary of Geological Reserve and Mining Parameters The mining lease area exposes rocks like norite and pinmatites which have suffered variable degree of weathereing and alternation. Pegmatites are observed to have been emplaced along the joints of norites as intrusive and occure as disintegrated mass with insitu of resitant quartz core of variable shape and size. The penmatite in western side of the area found to be to be the extension of a massive pegmatite which has emplaced along the E-W trending joint plane of norites. Based on the mutual field relationship and deposition of litho units encountered the tentative stratigraphy Norite, pegmatite and soil from bottom to top. The lower contour of the area covered with black cotton soil which may be product of high degree of weathering of norites. The colour of the soil of black to grayish black and clayey in nature. As per the approved mining plan geological reserve of Quartz in the area found to be 113112 metric tonnes out of which 80468 metric tonnes of proved reserve and 32644 Metric tones of probable reserve. Mineable proved reserve in the area is 80037 metric tones and probable reserve of 32228 tonnes total reserve of the area is 112265 metric tonnes of Quartz. The proposed production target 7020 metric tonnes per annum of quartz. Mining of semiprecious stone from the area is not economical. Semi mechanized opencast method of mining shall be followed to be deployed are DTH drill, Compressor, Excavator , Loader , Dumper, Water tanker, Light vehicle etc. A total of 17 persons will be employed. Semi Mechanised mining is being used for mining of Quartz The width and height of the benches will be kept at 5m and 3 m respectively while the overall slope will be < 45O. The recovery factor for salable grade Quartz has been taken as 80% as per the computation in the mining plan. The grade of the Quartz material will be SiO2-99.47%-99.75%, Fe2O3 0.04% to 0.60% Al2O3 content varies from 0.04% to 0.18%. The average SiO2, Fe2O3 and Al2O3 content of quartz of the area is 99.35%, 0.26% and 0.06% respectively.. As per the approved mining plan the total waste/OB generated from the mines is 3509 cum in 5 year plan period and 7717 cum in conceptual period totaling 11226 cum (by taking striping ratio to be 1:0.099). Existing and Proposed land use as follows: Land Use Existing Plan Conceptual Total Land in Ha. Periad in Period in Use in Ha. Ha Ha.

The OB material shall be dumped in dump yards and used for reclamation of mined out area and road making. The area of the dump ultimately will be over 0.500 Ha and height can be raised to 1 m with one terrace. Thus the total capacity of the dump will be about 5000 CuM. The mine require 4 cum/day of water for mining and allied activity and shall be drawn from surface water sources. No discharge shall be there from the lease area. However in rainy season part of the surface run-off shall be discharged with due treatment. The quarzite produced from the mines shall be utilized by Paper, soap, Paint, cosmetic, rubber industries and other plant of state and country. A total degraded land will be under plantation after the mining operation leaving behind the infrastructure, road and public use area etc. Due to continual of mines the socio-economic condition of the area shall improve. Project proponent shall take necessary steps to prevent the air, water and noise pollution. An amount upto 10% of profit shall be utilized for CSR activity.
