Capital proposed for the quarrying is Rs. 13 Lakhs. 2. Introduction of the Project / Background Information: i) Identification of Project and project Proponent In Principle of quarry lease called for by Department of Mines and Geology, Government of Andhra Pradesh vide Notice No. 10168/R1-1/2011 dated 04.07.2011. Mining plan is approved by the Zonal Joint Director of Mines and Geology, Visakhapatnam, Government of Andhra Pradesh vide Letter No. 2662/MP/11 dated 30.07.2011. ii) Brief description of nature of the project The mining operations are in the view of shallow nature of the deposit; open cast mining method shall be adopted in a semi mechanized manner by forming benches of 6m height. Hydraulic excavator and compressor jack hammers were used for cutting the rock. Therefore the machines selected and the operational pattern and timings form important details for arriving at the impact on environment. Need for the project and its importance to the country and or region The demand for granite increased due to rapid industrialization and growth in infrastructure. So the number of granite producing quarries is increasing in India. Granite is the chief material for the export industries like monuments, flooring slabs, Kitchen articles, 1 | P a g e Pre-Feasibility Report Excellent Granites sculptures & export. Based on the demand of Granite, the lessee intends to produce the required quantity of Colour Granite for domestic market. iii) Demand - Supply Gap The project is envisaged to meet the demand supply gap in both domestic market and export market, as Granite demand is increasing day by day. iv) Imports Vs.

M/s. Excellent Granites proposes to conduct semi mechanized open cast quarrying for colour granite average production of 1200 m3/Annum. The proposed Quarry lease area of 2.825ha in Survey No. 388, Binnala Village, Kanchili Mandal, Srikakulam District, Andhra Pradesh. The quarry lease area falls in the Survey of India topo sheet no. 74A/12 on Latitude 19° 1'35.55"N and Longitude 84°35'6.27"E with an elevation of 35m. The nearest village is Binnala at a distance of 0.5km from the QL area in SW direction. Nearest Railway station is Jhadupudi at a distance of 3.0km in NE direction. Nearest town is Palasa at a distance of 33km in SW direction. NH-5 Road Srikakulam to Bhubaneswar is passing at a distance of 2.9km from the QL area in SE direction. Arjunapuram- Yekkala village road is passing at a distance of 0.7km in West direction. The lease area can be accessible through a cart track. Bahuda River is flowing at a distance of 8.7km from the QL area in NE direction. Jalantrakota reserve forest is at a distance of 2.9km in SW direction. Shandhabhuja reserve forest is at a distance of 5.3km in NW direction. Andhra Pradesh and Orissa interstate boundary is at a distance of 0.3km in NE direction. There are no national parks, wildlife sanctuaries and critically polluted areas observed in 10km radius from the quarry lease area. Location map of the mine lease area is presented in figure 1. iii) Details of alternate sites considered and the basis of selecting the proposed site, particularly the environmental considerations gone into should be highlighted. No alternative sites considered, the proposal is existing mining project and it is site specific. iv) Details of Reserves and Life of the mine The information obtained from the boulders and exploratory openings in the adjacent area, the ‘proved’ category reserves are estimated to a depth of 5m from the surface. The average length of the deposit is taken as 205m and the average width is taken as 75m depending on the granite exposed in the area. Further a 5m depth from the base of the proved one, is considered for the estimation of the reserves under the ‘probable’ category and 5m zone below the probable zone is considered for estimation of reserve under the ‘possible’ category. The reserves available in the lease are complied as stated below table.

Hydraulic excavator, compressor jack hammers and wire saw cutting will be deployed for cutting rock. The separation of blocks from the mother rock will be carried out by drilling, wedge cutting, blasting, excavation will be done by the machinery. vii) Raw material required along with estimated quantity likely source, marketing area of final product/s, mode of transport of raw material and finished product No raw material is required, project is for mining granite. The extracted granite is mainly sold for export (contingent on the quality) and or in domestic market. 4 | P a g e Pre-Feasibility Report Excellent Granites Figure 1. Quarry lease location map viii) Resource optimization/recycling and reuse envisaged in the project, if any, should be briefly outlined. During the plan period waste material will be dumped in the dump area in SW side of the quarry lease area. The waste generated will be used for backfilling in the worked out pits after completion of mine workings. The reclaimed land will be cover with top soil and green belt will be developed to get rehabilitation. Some of the material from the waste may be sorted out and used for making small blocks known as ‘Khandas’ to be used by the local unit for making tiles. The market for tiles is good at the moment and they will offer better substitute for marble in terms of price and quality. Some rejected and unsorted material may be used in the civil engineering projects in the vicinity of the area.
