Ms. No. 407, Ind. & Comm. (M.II) Dept. dated 10-07- 1981. The mining lease deed was executed on 27-11-1981, vide Asst. Director, Mines & Geology, Nellore, Proceedings No. 700 / M1 / 1981 dated 27-11-1981 for a period of 20 years with effect from 28-11-1981 to 27-11-2001. 2.2 Brief Information about the Project The mining lease area of 63.00 ha. is located in Pattaland. Underground manual mining is followed and it has been proposed to produce Quartz - 222312 Tonnes/Annum, Feldspar – 1522260 Tonnes/Annum, Mica – 22250 Tonnes/Annum. Tummalatalupur village is about 0.9 km due North. 2.3 Need for the Project and Its Importance to the Country or Region Mica is having high insulation property. One mill thick Rubi Mica can stop 10,000 volts. The mica will not deform even at very high temperature. This is an important requirement for space machinery. Most of the mica produced in India is exported to developed countries. Scrap Mica is utilized in forming various products like Micanite PFR-II PROJECT: M/s. Nellore Mica Mine Association PRE-FEASIBILITY __________________________________________________________________________________________ Sheet, Mica Tapes & Mica powder. They are used in electronic machinery. Green Mica is present in the mining lease area. Feldspar containing 12%+ Allumina is used in Ceramic Industry and Sanitary Ware. Electric Ceramic Insulators for over head lines are made from Feldspars. This is used in India and export demand is available. Quartz is used in Glass Industry. High quality quartz is used to make semiconductors which are essential for electronic industry. The demand is available for Quartz in India and outside. As the separated state of Andhra Pradesh is now growing rapidly and many industries are coming up. These minerals will be helpful as raw materials in industries and the As per National Green Tribunal Judgment pronounced on 13.01.2015, the proponent has applied to State Level Environmental Appraisal Committee/State level ImpactAssessment Authority of Andhra Pradesh to obtain Environment Clearance. 2.4 Demands-Supply Gap There is huge demand since theseminerals are used extensively in industries and many other sectors. This project will help in reducing the Demand-Supply gap in the area. 2.5 Domestic/ Export Markets The material is used in the domestic market and in there is no scope for exporting the material. 2.6 Employment Generation Mining will be undertaken by manual underground mining method and this project operation will provide livelihood to the42 workers. It will provide employment to the people residing in vicinity. 3.0 PROJECT DESCRIPTION 3.1 Type of Project Including Interlinked and Interdependent Projects, If Any. PFR-III PROJECT: M/s. Nellore Mica Mine Association PRE-FEASIBILITY __________________________________________________________________________________________ The proposed mine area is of2.33ha.area. No interlinked projects are associated with this project. 3.2 Location of the project The mining lease area is located in Survey No. 216, PerumallapaduVillage, SydapuramMandal, S.P.S.R. Nellore district,Andhra Pradesh. The mine lease area falls in Survey of India Toposheet No.: 57N/11.

The lease follows Underground manual mining. 3.5 Geology and Reserves 3.5.1 Topography The mining lease area is part of Nellore Mica Belt (NMB). The NMB area is plain except for some mounds or hillocks consisting of resisting rocks. The average elevation of land is 50 Mt above Mean Sea Level. The rain water is drained through seasonal nallahs / gullies into Pennar River which empties in Bay of Bengal. Some low lying land areas are storing water and the water is used for agriculture. Some artificial ponds are constructed to store rain water for use in agriculture. The mining lease area is having maximum relief of 3 Mt from NW to SE. There is one open excavation measuring 20 / 30 Mt on surface and an underground mines opening from the bottom of the open excavation. There is no cultivated land in the mining lease area. 3.5.2 Geology The Nellore Mica belt is about 110 Km long from Vinjamoor in the North to Ozili in the South. The width of Mica belt varies from 10 Km to 30 Km. The Nellore Mica belt is located between 14o to 15o North Latitudes and 79o 35” to 80o Eastern Longitudes. The depth of Pegmatite varies from 10 to 350 M. The dips of Pegmatite lances are 45o to 80o towards West. This Nellore Mica belt is divided into 6 zones as detailed below. N E 1. Northern Pennar on the North most portion L 2. L Tatipatri - Prabhugiripatnam O 3. R Podalakur – Talupur E 4. Kalichedu M I 5. Utukur - Sydapuram C A B E 6 Chennur – Kadivedu on the South most portion L T PFR-VII PROJECT: M/s. Nellore Mica Mine Association PRE-FEASIBILITY __________________________________________________________________________________________ The mining lease area is in the 3rd zone, namely Podalakur – Talupur. The granites and pegmatite have intruded into schists of KandraVolcanics, which contain Quartz, Biotite and Hornblende Schists. Under favourable conditions, Muscovite books of commercial grades have formed by intrusion of pegmatite into schists. Hundreds of Mica Mines were worked in the Nellore Mica belt. The available information is Rubby Mica was found in 4th & 5th zones and green mica was found in other zones. REGIONAL STRUCTURAL FEATURES The trend of rocks is NNW to SSE. Extensive disturbances took place due to repeated intrusions of pegmatite and granite. This resulted in faults and metamorphism of strata mica books formed were disturbed and parallel or en-echelon pattern of pegmatite lenses were formed. Presently some of the pegmatite lenses are hidden below surface. Soil cover of 1 to 3 Mt thick is present. LOCAL GEOLOGY A pegmatite lense is outcropping in the mining lease area. The dimention of the pegmatite on surface is 25 Mt wide and 50 Mt long. The country rocks is hornblende – biotite schist. This was worked earlier upto a dearth of 48 Mt. Three levels at 30 Mt, 40 Mt and 48 Mt depth were excavated. The pegmatite lense shows a slight north plunge at 48 Mt depth. The dip of pegmatite is 60o towards west.
