K. Thimma Reddy Pre-Feasibility Report Kempegowda International Airport-– 261 km-SW Nearest airport Project Cost Rs. 40 lakhs INTRODUCTION OF THE PROJECT/ BACKGROUND INFORMATION Identification of Project and Project Proponent The project area is found to have good deposits of Quartz. The Quartz from this area will be sold to the Ferro Alloy Industries, Foundries, Ceramics and to Glass Industries located in and around Andhra Pradesh. Sri. K. Thimma Reddy is the Managing Partner of the project. He had significant experience in Quartz mining. Brief Information about the Project The mining lease area of 4.656 ha. is located in Government land. Open cast manual mining is followed and it has been proposed to produce approximately 75704 Tons/ annum of Quartz. The nearest habitation, Chinnahyata Village is located at a distance of 0.68 km due South from lease area. Need for the Project and Its Importance to the Country or Region Quartz is the most abundant and widely distributed mineral found at Earth’s surface. It is present and plentiful in all parts of the world. It occurs at all temperatures and abundant in igneous, metamorphic and sedimentary rocks. It is highly resistant to both mechanical and chemical weathering. This durability makes it the dominant mineral of mountaintops and the primary constituent of beach, river and desert sand. Quartz is ubiquitous, plentiful and durable. The demand for Quartz increased due to rapid industrialization and growth. Quartz is used in FerroAlloy Industry within and outside A.P. As per EIA notification 2006 the project falls under Category- B, the proponent is submitting the proposal to get Clearance for production capacity of 75704 tons/ annum of Quartz from DEAC, DEIAA, and A.P for the purpose of grant of quarry lease. 2 Quartz Mine of Sri. K. Thimma Reddy Pre-Feasibility Report Demands-Supply Gap The demand for quartz has been steadily increasing over the years to the requirement of ferro-silicon, silica refractories, glass and for moulding and casting purposes. The requirements of these products except glass are linked directly with iron & steel industry including alloy steel production. Further, setting up foundries and enhancing their capacities are also linked with metallurgical industry. It is reported that glass industry is expected to grow by 10% every year due to rapid rise in infrastructural activities in the country. At present the domestic market for quartz crystal components of the annual demand is about 13 ~ 1.6 billion, annual growth rate of nearly 20%. Domestic/ Export Markets The Quartz of this area will be sold to the Ferro Alloy Industries, Foundries, Ceramics and to Glass Industries, Located in and around Andhra Pradesh. Employment Generation Proposed mining is with manual method and this project operation will provide livelihood to the 25 workers. It will provide employment to the people residing in vicinity. PROJECT DESCRIPTION Type of Project Including Interlinked and Interdependent Projects, If Any. The Quartz mine is of 4.656 ha. No interlinked projects were associated with this project. Location The mining lease area is located in Sy.No.194 of Chinnahyata Village, Holagunda Mandal, Kurnool District, and Andhra Pradesh.

Thimma Reddy Pre-Feasibility Report Details of Alternate Sites No alternate site was considered as the project is mineral specific and site specific. Size or magnitude of operation The proposed mine has lease over an area of 4.656 ha and the production rate is 75704 tons/Annum. The lessee follows open cast manual mining. Production parameters The Mineral production target for two years is given in Table 3.1 in Tons Bench Year Height in (m) White Quartz Wastage@ @ 90% 10% 1st year 6 75704 3235 2nd year 6 74300 3175 3rd year 6 65735 2809 4th year 6 66634 2848 5th year 6 54335 2322 336707 14389 Total Geology and Reserves Local Geology The quartz of the subject area one such tabular quartz body with in Granite terrain. The quartz vein is trending NNW-SSE almost occurring the central part of the leasehold area with dip vertically. The length of Quartz vein is about 500mts with width of 30mts (max). The Quartz is exposed to a maximum thickness of 3m to 4m in pits. The country rock Granite is well exposed at lower reaches on western side of QL area. 6 Quartz Mine of Sri. K. Thimma Reddy Pre-Feasibility Report Regional Geological setup The Geological formations in the Ananthapuramu District can broadly be divided in two distinct and well marked groups and older group of Metamorphic rocks belonging to Archean and Younger group of Sedimentary rocks belonging to the Proterozoic age the later cover part of Gondwana block. The remaining parts of District are occupied by Archean Rocks which consist of Schist, Gneisses, Quartz veins and basic dykes. The Archean rocks have suffered considerable degree of tectonic disturbances, as a result of which the rocks have been metamorphosed and recrystallized. Reserves During last 11 years about 93650 tons of White Quartz was excavated from this lease area. SO the Mineable reserves of White Quartz available in the area are 2235615 tons and (2235615-20576). InAMP the proved reserves were estimated up to 125 F RL and probable and possible reserves work estimated by taking another 5 mts & 5mts thickness below, proved zone respectively. At present workings have been reached up to 130 FRL only in working pit. So the revised estimation is not necessary because only limited production is produced from last 12 years . Total - Recoverable Reserves of Quartz -- 2678329 tons Non- Mineable Reserves:- The White Quartz reserves are going to be blocked under buffer zone and under final pit slope on all four sides of the area as per AMP. Under Final pit slope = Cross sectional Area x length x TF x RF White Quartz Total Non Mineable Reserves of Quartz =2678329 tons. Mineable Reserves = Total Recoverable reserves- Non Mineable reserves. Total mineable reserves of Quartz = 2678329 tons. Total mined reserves of Quartz= Nil Tons. Net Mineable Reserves of Quartz= 2678329 Life of Mine: 67341 tons of Quartz per year the expected life of mine is about = 2678329/67341 = 16.57 years. (Source: Mining plan) 10 Quartz Mine of Sri. K. Thimma Reddy Pre-Feasibility Report PROJECT DESCRIPTION WITH PROCESS DETAILS Method of Mining a) Type of Mining: It is proposed to mine White Quartz by manual open cast method. The mining will be continued at higher levels on Eastern side, Western side of the existing Pit-1 & Pit-II after leaving 7.5 Mts buffer zone along the boundary line. The mining activity is being carried out without drilling and blasting. The workings are carried out in four of five benches from the top of Pit-II. So it is proposed to develop the existing Pit-II towards Southern side by excavating 2 benches in mineral zone of 6 mts each. Based on previous year's production it is proposed to raise about 93650 tons of White Quartz per year in the next five year scheme of mining period. The year wise production details are given in Annexure - III and year wise workings are shown in plan of section plate.-4. The scheme of development and production for the next five years has been planned taking into consideration the nature of the deposit within the lease area. It is observed from existing working pit that the sheet quartz is exposed in depth of the working pit without any overburden and therefore the development of the quarry is confined towards depth of existing working pit in North side. The proposed year wise working area is demarcated on plan and section and it is enclosed as plate No.5. 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 will be required in the proposed project.
