1 PRE-FEASIBILITY. Overview: REPORT Mica is widely distributed and occurs in igneous, metamorphic and sedimentary regimes. Mica group represents 34 phyllosilicate minerals that exhibits a layered or platy structure. Commercially important mica minerals are muscovite (potash or white mica) and phlogopite (magnesium or amber mica). Granitic pegmatites are the source of muscovite sheet, while phlogopite is found in areas of metamorphosed sedimentary rocks into which pegmatite rich granite rocks have been intruded. It possesses highly perfect basal cleavage due to which it can easily and accurately split into very thin sheets or films of any specified thickness. It has a unique combination of elasticity, toughness, flexibility and transparency. It possesses resistance to heat and sudden change in temperature and high dielectric strength. It is chemically inert, stable and does not absorb water. For over hundred years, India has enjoyed the monopoly in the production and export of sheet mica in the world. Of late, there has been a steady downfall in the production of mica. This declining trend could be attributed to fall in the demand of natural mica in the world market due to technological improvements that facilitate use of reconstituted mica and emergence of mica substitutes. However, there are sufficient resources in the country to meet the domestic requirement and export demand. Most important mica-bearing pegmatites occur in Andhra Pradesh, Bihar, Jharkhand, Maharashtra and Rajasthan. Occurrences of mica pegmatites are also reported from Gujarat, Haryana, Karnataka, Kerala, Odisha, Tamil Nadu and West Bengal. As per UNFC, the total resources of mica in the country as on are estimated at 532,237 tons out of which 190,741 tons are placed under reserves category and 341,496 tons under remaining resources category. Andhra Pradesh leads with 41% share in country's total resources followed by Rajasthan (21%), Odisha (20%), Maharashtra (15%), Bihar (2%) and balance (less than 1%) in Jharkhand 1

2 INTRODUCTION: This mica mine deposit was initially leased in favor of M/s Chatturam Horilram (Pvt) Ltd, Jhumritelaiya, District Kodarma (Jharkhand) in Chatkari village in thana No.-290 (Rajouli), District: Nawada, Bihar for the area of 1, acres or ( hectare) in the forest area and mining operation was already been done by the Messrs Chatturam Horilram (Pvt) Ltd in the same area. It was surrendered to the state government of Bihar. The surrendered Notification was published in the notification of Bihar vide Gazette no-11, dated 14th March On the basis of the aforesaid notification, M/s Sharda Mica Mining Co. applied for Mining lease for the part of same area i.e Chatkari village only in thana No.-290 (Rajouli), District: Nawada, Bihar for the area of acres or ( hactares) and Mining Lease was granted & executed on 5th March, 1986 for the period of 20 years. After grant of mining lease area, mining was consisted in block no- G/3 (37.83 acres) & H/4 (6.17) i.e. total area in both block acres (17.81 hectares) only, due to reach deposition of mica. However, signing of pegmatite & mica schist is also observed in rest of the lease area i.e hactares. The period of 20 years of the mining lease was expired on 04/03/2006. Therefore, renewal application was applied for the area of acres or ( hactares) on 03/03/2005 to the state Government Bihar. And renewal application is still pending to the State Government of Bihar.

10 PART A CHAPTER-3 GEOLOGY AND EXPLORATION 3. GEOLOGY AND EXPLORATION: 3.1.(a): Briefly describe the topography and general geology and local / mine geology of the mineral deposit including drainage pattern Topography: The area represents a rugged topography with a number of hillocks and very small nullahs in a repetitive manner. The highest hillocks are situated towards NE of the lease area. The maximum and minimum heights attained by the area are 323m and 220m from the M.S.L. respectively. There are three very small nullahs, which is crossing towards south to east of the lease area and are joined into one towards north east Nadi and flows from south to north east direction. These nullahs are seasonal and most of the times are dry except in rainy season. No public road is passing through the lease area. The lease area is approachable from the Jhumri Telaiya.(NH-31) to Niru Pahari towards East (about 14 Km) and Niru Pahari to Chatkari village towards North up to 20 KM through tar road. Chatkari village to lease area is Kacha (Jeepable) road about 1 KM towards west. Chatkari village on the east is most populated in the region. The area falls under the square nos. E/3, E/4, E/5, E/6, F/2, F/3, F/ 4, F/5, F/6, G/3, G/7, H/4 and H/7 part in protected forest. The entire area is covered with thick vegetation of thorny bushes and small trees. 3.2: REGIONAL GEOLOGY: The Koderma district and the lokai-indarwa area cover the southern part of Great Mica- Belt of Jharkhand and Bihar. Previously the Mica belt was known as Bihar mica belt which extends for a distance of 160 km having an average width of 25 kms. The mica belt stretches from Gurpa in Gaya district in the west through Nawada, Koderma, Hazaribag, Giridih in Jharkhand and Jamui as well as Bhagalpur district of the Bihar state in the east. Its maximum width is about 40 km at Koderma- Hazaribagh-Nawada area. The whole belt encompasses roughly 4,000 sq. km. around area and lies on the north fringe of Chotanagpur plateau and runs in an east-north east to west south west direction. The type of rock exposed in the region consists of a series of meta- sediments like Mica-schist, quartz-schist, Micaceous-quartz-schist, hornblende schist and para amphibolite. The group of gneissic rocks consists of granite-gnesis, biotite-gnesis of Chhotanagpur granite gneissic complex which are younger to Meta sediments in age and are also occurring in association with the above rocks. The Mica schist is inter- bedded with bands of hornblende schist, talc schist, granulite and gneiss, Micaceous quartzite, several granitic bodies intruded all these rocks. The coarse granite rocks are showing chilled contact effect with the adjoining gneisses rocks and show a faint foliation near the contact. On the other hand the granite & 10

11 schist are traversed by the dykes, quartz veins and pegmatite & mica schist. The pegmatite & mica schist penetrates the schistose & gneissose rocks used as tools of Mica search on surface. Mostly the Mica is occurring in the pegmatite & mica schist s. The majority of the pegmatite & mica schist originates through the digestion & recrystallizations of mica schist. The pegmatite & mica schist generally consists of plagioclase feldspar, quartz but in few cases it also contains garnet, tourmaline, and beryl. In Mica belt the granitic rocks constitute about 33% of the total area; some are Domeshaped and lie in the surrounding area of the belt, whereas the metamorphic rocks is situated about 67% of total Mica belt. General Geology :- Chhotanagpur granite gneiss- Unclassified meta sedimentary: Alluvium/soil.-Unconformity Dolerite Pegmatite & mica schist & quartz veins. Intrusive granite. Porphyroblastic granite gneiss. Complex: Granite gneiss. Migmatitic granite gneiss. Amphibolites, harnblende schist Mica schist, quartz Mica schist Micacious quartz schist,quartzite 3.3: LOCAL GEOLOGY: The entire area is covered with two litho logical units namely mica schist and pegmatite mica schist. The occurrence of major part of the area is recorded as mica schist with the emplacement of mica at places. Mineralogically the mica schist is comprised of quartzbiotite and muscovite with garnet and tourmaline at some places. Mica schists are altered much by heavy weathering and that has created problems to ascertain its behavior and trace its continuity in the surface. Pegmatite & mica schists are emplaced in the favorable locale such as schistosity plane, joints and hinge area of folds. In general the pegmatite & mica schists are comprised of medium to coarse grained quartz, feldspar (both plagioclase and potash), muscovite, biotite, tourmaline and garnet. The pegmatite & mica schist s which are associated with muscovite mineralization are designated as mica-bearing pegmatite & mica schist and the pegmatite & mica schist which are devoid of mica mineralization are designated as barren pegmatite & mica schist. Structurally it appears that some pegmatite & mica schist s are emplaced as pre-tectonic masses whereas the other type is found to be post-tectonic bodies. The major planar structure of the area is schist which is well defined by the preferred orientation of platy minerals. Geology of applied area follows the same trend of regional geology of the area. Stratigraphically the area belongs to M.H. Vaishnan area and proved by exploitation of Pegmatite & mica schist s over the previous lease period & as per geological plan and section. The massive pegmatite & mica schist has already been opened in the hill towards north east portion i.e. block no.-g/3 & H/4. Mica schist is altered much by heavy weathering and that has created problems to ascertain its behavior and trace its continuity in the surface in peripheral part of the area but in this position, deposits of mica debra is more chances in quantity in this situation. Presently two pits are working in the lease area i.e. pit no-1 & pit no-2. Both the pits are situated in the slope of the hill. Pit no-1 is south east and another is eastern side around the hill slope. 11

12 The overall thickness of massive pegmatite & mica schist is exposed up to the hill top i.e m. General strike direction of massive pegmatite & mica schist is 155-m NW-SE with dip amount is 85 0 towards SW. While the RL wise the mineralization is reached in between 133m RL (upper portion) to 109m RL (bottom portion). 3.4: AREA OF ML: ha Area of mineralization: Both quarries including hill portion is considered mineralized Zone in the block no: G/3 i.e. total area ha. The other details of the area as follows: GEOLOGICAL CHARACTERISTICS OF THE APPLED LEASE AREA Pegmatite & mica schist with Mica mineralization: ha ( Keeping 155 m influence from the pit face) OB Cover avg. thickness: 3 M. Shiest with Mica / Pegmatite & mica schist depth is measured from 24 m and is taken over the G/3 AREA (continued exposed thickness) Strike 155m Dip 85 0 N Physical Characteristics: Color: mix Form: massive, fine to medium grained, Sp. Gravity: 2.7.0T/CM Waste Material: All the materials not conforming to the specifications of required grade of mica and which are required to be handled for mining out the ore, have been termed as waste material. The waste materials may be classified into the following forms: (i) Overburden, overlying the ore body and the barren portion within the ore body. (ii) Mica & Mica waste/ Dibhra filled within the granite & schist are traversed by the dykes, quartz veins and pegmatite & mica schist and barren portion in between the ore body. (iii) Stripping waste to be handled in the pit/bench slopes during excavations for maintaining the 3m high benches. Quantum of waste: Total quantum of the waste required to be handled in respect of the total proved reserved has been computed under two heads: (i) Soil cover or overburden (O.B) (ii) Inter-burden including within the granite & schist are traversed by the dykes, quartz veins and pegmatite & mica schist and barren portion in between the ore body. The quantum of the total stripping waste depends upon the actual total extent of the quarries to be finally explored. Hence there is a scope of enhancement of the total waste material in future depending upon the extent of excavations. 12

13 3.5. Details of Exploration: i) Exploration already done in the area:: Presently, massive pegmatite & mica schist vein has already been seen in the hill as well as in working quarry no-1 & 2, which are carried out through open cast mining. Same pegmatite & mica schist vein will be worked in future also till the continuity of the pegmatite & mica schist to some extent by underground development also.

Presently mining will be carried out in the massive pegmatite & mica schist vein deposited in the hill portion through opencast mining, after finished of massive pegmatite & mica schist vein deposited in the hill portion than mining working will be converted in to underground mining along with massive pegmatite & mica schist vein. When the bench levels will be formed extension holes will be put across the pegmatite & mica schist in both footwall and hanging wall on each level to prove the existence of any parallel pegmatite & mica schist. Extension holes shall be put at an interval of 15m to 20m in a staggered way in the vertical plane. The length of holes will from 10m to 15m depending on the circumstances. Extension holes of 32mm diameter will be drilled by jackhammers and the drill cutting shall be collected for examination Geological Reserve and Resource: (Computation of reserve by area of influence method): The mineralization in pegmatite & mica schist varies widely and the available present day exploration techniques have not been able to predict the degree of mineralization, with any level of confidence. The pegmatite & mica schist under consideration has not been explored at all. Reserved estimated on any assumption will not be a representative one. Thus estimation of reserved & grade of mica cannot be possible to 13

14 assess in the pegmatite & mica schist vein. However, in view of the massive pegmatite & mica schist is deposited in the hillock & method of mining was carried out by opencast mining, it has estimated the reserved as per seen in quarry of the hillock. The pegmatite & mica schist vein has been considered for development has got surface exposure at 133m R.L. It is expected that the strike length will increase and a strike length of 155m has been considered up to depth of 24m & 109m RL. Some amount of pitting has been done on this pegmatite & mica schist. In absence of any exploration its strike length could not be ascertained but from the locations of the pits and from the behaviour of the parallel pegmatite & mica schist in the depth of present working an average strike length of 155m it considered to be a reasonable assumption. (All the reduced levels mentioned in drawings and reports are based on the assumed reduced levels of 24m in depth for the proved of the leasehold. It has got no relation with the bench mark). The width as observed in both the pits and surface varies from 14m to 40m and for the purpose of planning an average width of 27m has been considered. As per above, stated in the geological reserve as per UNFC classification for mica mine cannot be possible to assess in the pegmatite & mica schist vein. However, Geological reserved are assessed in view of the past five year production achieved in the pegmatite & mica schist vein& schist as shown in the Yeses Plan. (Enclosed as Plate No-Z and accordingly Feasibility study Report has been prepared, which is enclosed as Annexure : RESERVE: Geological reserves are assessed in view of the past five year production achieved in the pegmatite & mica schist vein & schist as shown in the Yeses Plan. (Enclosed as Plate No-Z). All the R.O.M (waste or dibhra) is manual dressing, sizing & sorting etc is done at the mine site and waste or dibhra mica is packed in gunny bags and transported to the beneficiation plant at Jhumri Telaiya, District Koderma. By processing Mica waste/waste/r.o.m. waste or dibhra mica are processed & upgraded. A Chemical analysis of the product is not required in mica. So upgraded mica or in form mica powder is sold to the consuming industries as per requirements of market or dealers/exporters : Recovery with cut-off grade & tonnage factor, method of assessment. a): Cut off grade: There is no cut- off grade because all the waste or dibhra mica raised from the pit shall be treated in the beneficiation plant & pulverising to make powder form. Further, the mica powder product is being sold on the basis of sample and not on the basis of any fixed analysis. b): Recovery: Based on the experience of mining operation of last few years, it is observed that recovery of Mica waste/waste/ r.o.m. waste or dibhra mica is -1.5% from the pegmatite & mica schist and schist zone whereas 98.5% is intercalated waste. c): Conversion factor of waste mica: Specific gravity- wastes mica:

This area is considerably explored and economic viability and feasibility study have been carried out based on previous mining or mined out area i.e. yeses plan. The economic axis, feasibility axis and geological axis have been categorized and based on this UNFC codification the reserved and a resource is made. There is no non- mineable part of the reserved in the lease area due to statutory barriers and U.P.L. The resources and reserved estimated is given below:- Considering the above parameters, the different categories of geological reserved have estimated by cross sectional area method as follows.

The proved reserve has been estimated based on the actual thickness of the ore body as exposed in quarry faces. Thus, geological axis can be brought under G1. The massive pegmatite & mica schist body considered under proved category has been estimated with full confidence and there is no statutory restriction. Infrastructure resources are already available. Thus, the reserved can be brought under F1. On economic front, the end use, land use pattern, working plan is already known or designed, the ore of this area is commercial as to the demand of buyers, thus, and the reserved can be brought under E1. Thus proved reserved can be classified under 111 groups. The total lease area is ha out of that hectare mineralization Zone area has been considered in the block no: G/3. This area is considerably explored and economic viability and feasibility study have been carried out based on previous mining or mined out area i.e. yeses plan. The economic axis, feasibility axis and geological axis have been categorized and based on this UNFC codification the reserved and a resource is made. (b) Probable Mineral Reserve (122). As the floor and side walls of the existing pits and trial pits are in ore zone, a further influence up to 109 m R L depth and 5m laterally has been considered. This lateral 16

17 extension of the ore body is kept under probable category assuming that the ore body may continue further. Thus the geological axis can be brought under G2. On feasibility axis, there will be no displacement but the lease period has expired and area is under renewal, mining operation is being carried out under deemed extension period. Thus, the reserved can be brought under F2 On the economic front, based on previous extraction of mica from pegmatite & mica schist vein in the area, the grade of waste or dibhra mica is assumed to be the same. Hence it can be grouped under E1. Thus probable reserved can be classified under 122 groups. (c) Inferred Mineral Reserve (333). The total lease area is ha out of that hectare mineralization Zone area has been considered in the block no: G/3. But rest area hectare has not been explored but pegmatite & mica schist vein is exposed in several places with in the lease area. Therefore, mica is not exhausted in the lease area. In view of that the mica is available in pegmatite & mica schists, which are exposed in several places. But presently grade & quality of mica is un-known. The present market scenario this mica is not profit marketable so we keep it in E3. It also found that the quality of pegmatite & mica schist deposit is gradually low in depth wise. So we keep it G3 and F3 category. In this area there is only pegmatite & mica schist vein is exposed and it is failure of mineralization, thus inferred can be classified under 333 group has not been estimated.

To meet this requirement, existing quarry no. 1 &2 have been considered for the planned period. The total recoverable waste or dibhra mica of the area is 17

18 tons and (Debra). So, taking the maximum production target of 7570 tons or (Debra) per year, the life of the mine will be 100 years. Intercalated waste: The waste materials being generated from the working Quarry is mainly weathered soil and shiest etc. Besides that, there is a generation of intercalated waste which constitutes about 98.5% of the excavation in pegmatite & mica schist zone. These waste materials shall be dumped in the earmarked site which will later on utilized to reclaim the mined out area by backfilling & mine Road also 3.7: Grade: Chemical composition of the Mica:- Muscovite chemical formula for KAl2 (AlSi3O10) (OH)2; Magnesium Silicon muscovite chemical formula of (Fe2 +, M g) (Fe3 +, Al3 +) (AlSi7O20) (OH)4; sericite chemical formula for KAl2 (Si, Al) 4O10 (OH, F)2; The chemical formula for Mica KMg3 (AlSi3O10) (F, OH)2 ;Mica such aluminium silicate minerals, with continuous layered silicate structures, with the complete very cleavage, Stripping to be elastic sheet, quality soft curved, transparent colourless, with thick pieces of translucent gray, brown, light green, red roses, with glass pearls and silk or gloss, hardness 2.5 ~ 3, the proportion of , the acid.

19 CHAPTER 4 MINING 4. 0 MINING: 4.1: Briefly describe the existing / proposed method for developing / working the deposit with all design parameters : Existing method of mining: The work is confined in blocks i.e. G/3 & H/4 at present and mining is being carried out by the open cast method of mining with formation of benches by drilling and blasting and it comes under Category B (Other than fully mechanized category). Working benches are kept 3m high and 3 m wide. One or two benches in top hill and generally one top bench in the soil and another 2 nd bench are in overburden. During the mining operations will involve drilling, blasting, mucking, loading, transport of mica and waste etc. Certain operations may be used shovel & dumper for removal of overburden and others may be done manually. Drilling is being carried out by air leg mounted jackhammers. Compressed air supplied to the jackhammers from a portable tractor mounted compressor. Loading point of view mica & wastes are being transported by truck/dumper to user industries. Loading of mica & wastes in to truck dumper is being done manually. The last production (since to ) of ore is given below in the Table -2.

23 4.1.4: DETAILS OF YEAR WISE DEVELOPMENT AND ASSUMED PRODUCTION Five year development and waste dumps plans and also year wise plan & sections are shown in plate no-5,6,7,8 & : Indicate proposed rate of production when the mine is fully developed, and the expected life of the mine and the year from which effected. Mine life Because of the erratic distribution of mica in pegmatite & mica schist which can not be predicted by any exploration technique available as on date it is not possible to assess the reserved. In absence of the reserved estimate, the life of the mine cannot be determined. However, as per assessment of reserved as given in the para 3.6, Mine life has been estimated as: Production targeted 7050tonnes /annum. Reserved estimated as per UNFC: tonnes Mine life: /7050 = 100 years 4.1.6: CONCEPTUAL MINING PLAN FOR ENTIRE LEASE PERIOD/CONCEPTUAL PERIOD BASED ON THE GEOLOGICAL MINING AND ENVIRONMENTAL CONSIDERATIONS: i) CONCEPTUAL EXPLORATION: No exploratory work is proposed in fifth year development programme. Presently mining will be carried out in the massive pegmatite & mica schist vein deposited in the hill portion through opencast mining, after finished of massive pegmatite & mica schist vein deposited in the hill portion than mining working will be converted in to underground mining along with massive pegmatite & mica schist vein. When the bench levels will be formed extension holes will be put across the pegmatite & mica schist in both footwall and hanging wall on each level to prove the existence of any parallel pegmatite & mica schist. Extension holes shall be put at an interval of 15m to 20m in a staggered way in the vertical plane. The length of holes will from 10m to 15m depending on the circumstances. Extension holes of 32mm diameter will be drilled by jackhammers and the drill cutting shall be collected for examination. Present exploration is in the form of excavations & degraded in block G/3 of ha, the massive pegmatite & mica schist is deposited in the hillock. The pegmatite & mica schist vein has been considered for development has got surface exposure in the pit no 1 & 2. It is expected that the strike length of 155m has been considered up to depth of 24m & 133mRL to 109mRL. EXPLORATION The mineralization in pegmatite & mica schist varies widely and the available present day exploration techniques have not been able to predict the degree of mineralization, with any level of confidence. The pegmatite & mica schist under consideration has not been explored at all. Reserved estimated on any assumption will not be a representative one. 5

24 Thus estimation of reserved & grade of mica cannot be possible to assess in the pegmatite & mica schist vein. However, in view of the massive pegmatite & mica schist is deposited in the hillock & method of mining was carried out by opencast mining, it has estimated the reserved as per seen in quarry of the hillock. The pegmatite & mica schist vein has been considered for development has got surface exposure at 109 to 112m R.L. ii) CONCEPTUAL DEVELOPMENT a): The work is confined in on blocks i.e. G/3 at present and mining is being carried out by the open cast method of mining with formation of benches by drilling and blasting and it comes under Category B (Other than fully mechanized category). Working benches are kept 3 m high and 3 m wide. One or two benches in top hill and generally one top bench in the soil and another 2nd bench is in overburden. During the mining operation involve drilling, blasting, mucking, loading, transport of mica and waste etc. Certain operations may be mechanized and others may be done manually. Drilling is being carried out by airleg mounted jackhammers. Compressed air supplied to the jackhammers from a portable tractor mounted compressor. Loading point of view mica & wastes are being transported by truck/dumper to user industries. Loading of mica & wastes in to truck dumper is being done manually. b) Following pits are available in the area at present: Both quarry are converted in to one quarry as given in table 9. PIT NO.

Soil to be generated =435cum Following pits will be available at the end of conceptual period During this period old dumps will be re-handled and following pit will not be available. 6

25 4.1.9: CONCEPTUAL OVERBURDEN DUMP MANAGEMENT: The Conceptual dumping area is chosen within the block no G/3 ultimate pit limit on ground which may not cause any land or water pollution. a) Following OB dumps are available in the area Presently there is 81258cum OB dumps within the block nog/3 or lease area b) Following OB dumps will be available at the end of proposal period: During the proposal period cum waste will be generated & dumped within the block no-3 and part of it s will be used for road construction and its maintenance c) Following OB dumps will be available at the end of conceptual period: Present day exploration techniques have not been able to predict the degree of mineralization, with any level of confidence. The pegmatite & mica schist under consideration has not been explored at all. Dump estimated on any assumption will not be a representative one. Thus estimation of dumps cannot be possible to assess in the pegmatite & mica schist vein. However, in view of the massive pegmatite & mica schist is deposited in the hillock & method of mining was carried out by opencast mining, however, all the generated waste will be used at the time of stopping stage of the mine : Disposal of Sub grade mineral: No Sub grade mineral will be generated; all the ROM will be sold out. Environmental monitoring: Noise, air, water and other environmental parameters will be monitored periodically to have a close check on the environmental pollution. Spraying of water on haul roads, dust arrester on drills, prevention of vibration by utilization of minimum quantity of explosive per delay, massive plantation along road and other areas will be taken up to restrict the nuisance caused by mining activities. At the end of conceptual period the area will have water logged pits surrounded from all the sides by plantation, afforested dumps and minimum of roads with avenue plantation to reach the sites. As reflected in the table -10:- Table 10: (Afforestation plan up to conceptual period) Name of Block no. Location No. of saplings planted Area covered (Ha) G/3 Afforested surrounded pits, dumps & Roads Total Total leasehold area constituted forestland before the grant of mining lease.

Final sewing and packing of Mica flakes (2-8 mesh) take place in HDPE bags for export. j. In view to process the waste or dibhra mica upgrades their quality to make it marketable. Presently substitutes of mica are more used in the world in place of Natural mica. Substitutes of mica are very cheap in place of natural mica. Natural Mica in form of powdered are used in the paint and electrical goods etc.. Type of commodity with use: Mica waste and waste of mica in form of mica powder are used in paints, lubricants, Mica powder are produced after beneficiation & pulverizing. After pulverizing, mica powders is being dispatched or sold to the consuming industries as per requirements of market or dealers/exporters etc. ******** 3

38 CHAPTER 11- ENVIRONMENTAL MANAGEMENT PLAN 11.0 ENVIRONMENTAL MANAGEMENT PLAN (a) BASE LINE INFORMATION: Each type of mining poses its own kind of environmental problems. It has therefore; become imperative to carry out the base line study for preparation of Environmental Impact Assessment Statement (EIAS) before the mining activity is taken up. With this end in view, the base line information s in respect of environment collected in course of field visit of the area are summarized below:- EXISTING LAND USE PATTERN: The area falls in the Koderma Protected Forest waste land & existing land use pattern of area is as follows:: Degradation Type Protected Forest waste land Particulars Existing in ha Other Old pits /trenches etc Nil Active pit Nil Old dumps Nil Active Dump 1.21 Nil Retaining wall settling tank & garland ) Nil Mineral Storage 0.06 Nil Reclaimed Area Nil Road Nil Infrastructure 0.1 Nil Greenbelt Nil Total Remarks i) The applied area is in the block G/3 having semi ordinary structures such as office, residence, garage have been made for the mines. The management has planted about 50 trees of species like Mango, Jackfruit, Guava, in this area. DETAILS OF LAND AROUND 60M & 500 M.RADIUS OF THE APPLIED LEASE AREA Distance North East South West 60m To Protected Protected Forest Protected Forest Protected 500m Forest waste waste land waste land Forest land waste land No habitation is observed in the proposed lease. In village Chatkari having a population around 3112 is the nearest village, which is situated 1.0 kms east of the area. Within a 4

39 radius of 2kms there is no village. Within 5kms radius there are two mixed jungles, one open jungle and one mixed jungle. The average elevation of the area is 320m above mean sea level. Open jungles and mixed jungle are having mainly sal trees whereas mixed jungles are having besides sal, other trees like Bamboo, Karanji etc. Though the concerned forest officials could not furnish the actual forest density of the area, but from mere observations crown density appears to be around 0.4 with mostly class III to class IV categories trees. In the applied area towards NE boundary is having semi structures for office, residence. Area of about 9000 sq.m. has been cleared of trees for the erection of above structures. ii) Water Regime: The area represents a rugged topography with a number of hillocks and has the radial drainage and water flow direction is in all direction but major sloping towards southwestern direction which joins in main sources during rainy session. There is no natural source of water in the applied area. However, the water resource is available in the form of hand pump dependency of people in core zone; there are two hand pumps near the mine site. Applied area general Ground water table: - 40M from the top of the hill in block G/3. (post monsoon) & 45m BGL (summer) BGL: 35M. The proposal are given quite above to GWT. III) FLORA AND FAUNA FLORA : Mostly sal trees occur in the area. The area is categorized as mixed jungle. Besides sal trees other trees like Sakhua, Karanji occur abundantly in the area. Towards the northern part of the area Bamboo forest is observed. Babul trees in plenty are noticed towards west. Another important and costly tree i.e. Khair is also observed at some places in limited numbers. FAUNA: The area contains both carnivorous and herbivorous animals. Domestic animals viz, Cow, Govt. etc. are seen grazing in the area. Amongst wild animals bear, deer and wolf are very common. Leopards are also reported on rare occasions in the forest. There is no wild life sanctuary or national park in the area. CLIMATE CONDITIONS: The area has a Salubrious climate which in general, can broadly be divided in to following three district seasons: November to February : Winter March to June : Summer July to September : Rain October to remains the transition period. Summer is very severe, maximum temperature is attained in late May and early June. In summer the maximum temperature rises to 35 to 40C. In winter the weather remains dry. Nights are coldest during late December and early January with a temperature around 30to 35C or so. Most of the precipitation occurs during the rainy season from south-west monsoon. Premonsoon shower occurs in June, December, February and March also experience rainfalls. The rainfall data is enclosed in Table-15 5

40 Table 15-Rainfall data YEAR ANNUAL RAINFALL TEMPERATURE 0 C IN M.M. MAXIMUM MINIMUM HUMAN SETTLEMENTS: Being located in the protected forest, there is no human settlement over there. There are a few semi permanent and temporary hutments in area of Sharda Mica Mine in the block of G/3 & H/4. Staff and security guards are living in the temporary hutments and also used as office in the block of G/3. The nearest habitant in Chatkari village where people regularly live is locate about 1.0 kms away from the area. Sharda Mica Mine of M/s. Sharda mica Mining Company is situated in the village Chatkari, Dist Nawada, State- Bihar. But District head quarter Nawada is not directly approachable. The lease area is approachable from the Jhumri Telaiya.(NH-31) to Niru Pahari towards East (about 14 Km) and Niru Pahari to Chatkari village towards North up to 20 KM through tar road. Human settlements are generally controlled by the chatkari village and river valleys. Cultivation and firewood selling are the main livelihood of the local villagers. Then total population of chatkari village is 3112 out of which 1500 are male and rest 1612 are female. About 50% of the total population belonging to Bhuiyan, Rajbarand Turiya caste falls under schedule caste category and 30 belonging to Munda community come under scheduled tribe category. All these 30 persons are employed in local mines. Only twelve scheduled caste persons are engaged in agriculture. Nearly 10% of total male populations are literate. Amongst the female population only 4 are literate. A primary health centre in the village is functioning regularly to look after the primary medical needs of the people in the nearby areas. VII) PUBLIC BUILDING, PLACES OF WORSHIP AND MONUMENT: There are no public buildings, monuments, places of worships and any establishment of tourist interest in the area applied for mining lease. However, in the nearby Chatkari village there is one temple. 6

41 VII) Whether the area falls under notified are under water Act The area does not come under the purview of above act. 11(b) ATTACH AN ENVIRONMENT IMPACT ASSESMENT STATEMENT DESCRIBING THE IMPACT OF MINING AND BENEFICIATION ON ENVIRONMENT ON THE FOLLOWING OVER THE NEXT FIVE YEARS (AND UPTO CONCEPTUAL PLAN PERIOD FOR A CATEGORY MINES) i) LAND AREA INDICATING THE AREA LIKELY TO BE DEGRADED DUE TOQUARRYING /PITTNG, DUMPING, ROAD, WORKSHOP, PROCESSING PLAN, TOWNSHIP ETC. I) LANDSCAPE AND LAND SUBSIDENCE The area represents a rugged topography with a number of hillocks and very small nullahs in a repetitive manner. The highest hillocks are situated towards NE of the lease area. The maximum and minimum heights attained by the area are 323m and 220m from the M.S.L. respectively. No exploratory work from surface is contemplated to be carried out. Presently mining will be carried out in the massive pegmatite & mica schist vein deposited in the hill portion through opencast mining, after finished of massive pegmatite & mica schist vein deposited in the hill portion than mining working will be converted in to underground mining along with massive pegmatite & mica schist vein in future. When the levels will be formed extension holes will be put across the pegmatite & mica schist in both footwall and hanging wall on each level to prove the existence of any parallel pegmatite & mica schist. After sorting out mica within the quarry, the generated waste will consist of mica schist. This will be disposed of at surface. This waste as it is does not support any plant growth. The maximum quantity of waste which will be generated during first five years will be m 3. The average height will be available for dump up to 15m. Thus the spread will be about 27087m 2. All the generated waste will be used at the time stopping stage of the mine. No development is expected from the mine and the waste generated out of stopping will be packed in the stops in future. However, the landscape over 15% of total area will be altered due to surface structure like office buildings, head frame etc. and by dumping of waste. To minimize the impairment to the vision it is proposed to plant the trees of the local species all around the waste dump and the surface structures. Besides, it will be tried to plant Bouganvilla creeper in the office and residential areas for beautification. The resident of officials and office of Sharda mica mine has already been setup near the mine. These are located at a safe distance away from the mine, thus eliminating dust and noise. II) AESTHETIC ENVIRONMENT AND TOURIST SPOTS (IF ANY) Proper development as per proposal will maintain the aesthetic environment and tree plantation will be done to restore the aesthetic beauty. III) SOIL & LAND USE PATTERN The land use pattern is government waste land and the soil negligible hence not considered under waste calculation. The existing land-use-pattern and land use after 5 years of working is given below: 7

42 Existing Land use: Degradation Type Protected Forest waste land Particulars Existing in ha Other Old pits /trenches etc Nil Active pit Nil Old dumps Nil Active Dump 1.21 Nil Retaining wall settling tank & garland ) Nil Mineral Storage 0.06 Nil Reclaimed Area Nil Road Nil Infrastructure 0.1 Nil Greenbelt Nil Total Remarks Land Use after the plan period: The land use after 5 years of workings would be as follows: Particulars At the end of 5 th year.-: Old pits /trenches etc NA Active pit Old dumps NA Active Dump 2.66 Retaining wall settling tank & garland ) 0.1 Mineral Storage 0.06 Reclaimed Area NA Road NA Infrastructure 0.1 Greenbelt Total IV) GOVERNMENT GM LAND: Not Applicable. V) FOREST: The area is located in the protected forest. Some amount of deforestation shall have to be carried out to accommodate surface structures like head frame, office buildings, quarry area etc. however, the total excavated /degraded land during past & present mining operations ha is covered within entire lease area i.e. block No. G/3 & H4 including certain areas where waste dumping will be built up may damage vegetation and all the mining activities will be carried out in G/3 & H/4 block only. 8

43 VI) Agriculture: There is no any agricultural land in the lease area. VII) PUBLIC BUILDINGS, PLACES AND MONUMENTS INCLUDING ARCHAELOGICAL SITES. \i). There are no public building, places and monuments including archaeological sites in and around 500 m. radius of the applied lease area. Cumulative land degradation: hectares. Details degradation of land is given below: Particulars Existing in ha At the end of 5 th year.- ha At the end of Conceptual Period: Old pits /trenches etc NA NA Active pit Old dumps NA NA Active Dump Retaining wall settling tank & garland ) Mineral Storage Reclaimed Area NA NA Road NA NA Infrastructure Greenbelt Total ii) Air quality: Mining activity is planned to be carried out in small scale and there will be no major impact on atmospheric air. However, certain amount of air pollution, though insignificant will take place by the following two ways:- A. FACTORS CONTRIBUTING TO AIR POLLUTION 1. Dust 2. Fumes of blasting and Exhaust (Noxious Gases) of machinery As earlier said mining activity dust generation will be due to movements of trucks and by mining activity, may pollute the air to some extent but spraying of water on road and faces before blasting and loading will control its generation. B. Sources of their generation like, 1. Dust: Traffic & Transport Drilling, blasting Loading, 9

44 Waste dumps This will be contained within permissible limit by spraying water on road and providing avenue plantation. Like adopting wet drilling, using sharp bits and dust collectors providing dust mark to operators, water infusion of benches before and after blasting adopting adequate blasting and drilling parameters and using proper explosive, spraying water on muck pile during loading, water spraying and use of bag filters in screening and plantation will further reduce the propagation of airborne dust. iii) WATER QUALITY: In the applied area there is no water stream course or springs.the mining will be done on the hill so it will not affect the ground water quality. Even the conceptual pit limit is not reaching below the GWT hence ground water quantity /quality will not be adversely affected. iv) NOISE LEVEL It will be created by movement of truck/ dumper drilling & blasting etc. However noise generated by these will be occurring at very low level as it being small nature of working. v) VIBRATION LEVEL (DUE TO BLASTING) Proposed mining operations will be done in small scale and Blasting is proposed which will be used on the hill. So it will affect the of ground vibration in transient nature. Provision of delays in firing sequence will also minimize the noise pollution. vi) WATER REGIME IMPACT OF MINING ON WATER ENVIRONMENT ON FOLLOWING HEADS: I) SURFACE WATER: The extent of mining excavation is too small to have any significant effect on the water regime. However, during rains, some amount of waste from dump will run down the nearby nullahs causing silting over there. But considering the total silt load in nullah water in rains, the additions will be insignificant. It dumps and growing vegetation over the dump surface. I) GROUND WATER: Use of water for mining purpose will be around 2KL for workers which will be managed by hand pump near the mine site. (The photo copy of the water analysis report is enclosed as annexure -10.) III) WATER QUALITY: From present status to conceptual period the proposal are given on the relatively at higher level which is quite above to GWT and the collected water during rainy or post monsoon season will be negligible. If any mines water discharge or dump wash will further pass to 10

45 the settling tank for settling down the heavy suspended particles then lastly it will drained to the nearby area. vii) SOCIO-ECONOMICS The impact on socio economics has already been a positive one because of the generation of several hundred unskilled/ semi-skilled jobs for which the local villagers are well suited. Additionally, villages) in the core zone have much better support facilities than those in the buffer zone. Similarly, educational levels are much higher in the core zone. As no agricultural land has been affected by mining & allied operations, there has been no adverse impact on agricultural activity. As part of it SOCIO economic concern activity, the management is helping out neighboring villages in respect to their day to day problems through installing hand pumps, constructing/ repairing approach roads and school buildings and helping in health care & family welfare activites. i). SOCIAL AND DEMOGRAPHIC The lease area is under forest area, therefore, no any parental human population are living within the applied area. But near the mine, only one village is situated i.e. Chatkari village. This village has the mixed population of adivasis, Harijans & Others. The demographic profile for this region shows on an average the population having cultivation 40% Agriculture Labour - 30% Under Industrial employment. - nil Marginal workers - 10% Unemployed - 20% About 85% of the cultivating land is poorly fertile and 40% of which cannot be used for regular cultivation. 20 % workers employed at this mine are all local villagers. Though the strength of workers employed at the mine is very low, but they will have a regular source of earning. Thus the mine has given a beneficial impact of improving upon the socioeconomic conditions of the villagers. II) OCCUPATIONAL HEALTH AND SAFETY This being an opencast mine the workers are exposed to the vagaries of weather. During summer there is likelihood of sunstroke and during winter there is effect of cold. Injuries to workers by slipping are sometimes reported. First-Aid facilities are available immediately at the mine. III) HUMAN SETTLEMENT There is no human settlement within the area but there are three villages within core zone with a total population comprise Adivasis (about 26% harizans, about 18%) and other class of people. The demographic data of the population for the core zone are given in Table. The villagers have cultivation as basic source of livelihood. But services mostly as workers in mines, road building and other related activities provide substantial contribution to their economy. About 19% average of the total population is literate. Primary education facility is available in Chatkari villages. There is one middle school in the core zone at Chatkari. There is one Primary Health Centers at Chatkari. 11

46 Demographic Profile Name of Population Literacy Cultivation Agriculture Marginal Unthe (%) (%) Labour (%) workers. Employed Village Chatkari Baratanr Simratari IV) RECREATIONAL FACILITIES. There will be no adverse impact of mining but up to some extent socio-economic environment of the area will improve as, the mining activity has already given the job to local people and will assure the job security of already engaged workers and it may create further new job opportunities for the local people. Further applicant will provide the occupational health and safety by providing regular medical checkup and medicine distribution. Further applicant will provide the recreational facility at the local people permissible demand. Proposed mining operations may improve the financial status of the local people. viii) HISTORICAL MONUMENTS ETC There are no historical monuments in and around 500 m. radius of the lease area. ENVIRONMENTAL MANAGEMENT PLAN: 1. TEMPORARY STORAGE AND UTILISATION OF TOP SOIL In general there is no any quantity of top soil will be generated only occasional cover is there which is negligible in quantum hence no stacking is required of top soil. However, about M 3 will be generated ensuing period, it will be used for plantation only. 2.year wise proposal for reclamation / rehabilitation of land affected by abandoned quarries and other mining activities during first five years (and upto conceptual plan period for a category mines) clarifying the extent of back filling and recontouring and/or alternative use of unfilled/partially filled excavations/road sides/slopes and mine in case abandoned quarries/pits are proposed to be used as reservoir, their, size, water holding capacity and proposal for utilization of such water be given. RECLAMATION AND REHABILITATION STATUS: a)present reclamation and rehabilitation is nil. b) Area under reclamation and rehabilitation by the end of proposal period is nil c) No backfilling will be available at the end of lease period. Presently, massive pegmatite & mica schist vein has already been seen in the hill and working is carried out through open cast mining and same pegmatite & mica schist vein will be worked in future also till the continuity of the pegmatite & mica schist to some 12

47 extent by underground development also. All the generated waste materials will be kept safely & utilized at the time of stopping stage of the mine. 3. PROGRAMME OF AFFORESTATION Progressive (Afforestation): This is a renewal case for ML, in ensuing years 1.0ha area will be afforested in green belt by 1250 plantations. Position at the end of year Plantation during the year (No. of saplings) Area covered during the year around the waste dumps (Area- HA) Survival rate Remarks LOCATION SPECIM NET A B C D E F 1 st year % north 2nd t year % North-west 3rd t year % West 4 th t year % West-south 5 th t year % south Total % 4. STABILISATION AND VEGETATION OF DUMPS Certain amount of deforestation will take place for construction of surface structure and for old dumping of waste. Care has been taken to dump the waste on areas having shrubs and Construction of Parapet wall. Compensatory a forestation programme will be undertaken near Sharda mica mine. A forestation also will be taken up all around the waste dumps as given above. 5. MEASURES TO CONTROL EROSION/SEDIMENTATION OF WATER COURSES. The mining operations will not have any adverse effect on ground water and surface water in the core/buffer zone, because during the next five years and conceptual period mining will be carried out above the ground water level. Although one settling tank has been proposed which will take of any sedimentation before discharging to main nallah course. 6. TREATMENT AND DISPOSAL OF WATER FROM MINE Rain water will not be accumulated in the working pit because proposals of mining will be carried out on the hill. If any circumstances rain water will be accumulated around the working pit than rain water will be pumped out to the surrounding through settling tank to the nallah. 7. MEASURES FOR MINIMISING ADVERSE EFFECTS ON WATER REGIME No adverse effect on water regime is expected as mining will be on small scale and there is no water body in the surrounding. 13

48 8. PROTECTIVE MEASURES FOR GROUND VIBRATIONS/ AIR BLAST CAUSED BY BLASTING Blasting proposal as given on para 5 will be strictly followed with all precautionary measures. Due to blasting ground vibration will generate which will be transient in nature as proposed mining is of small scale therefore this vibration will not have much impact. The protective measures will be taken by informing during blasting. The dust generated by occasional movement of blasting, trucks and by other mining activity, may pollute the air to some extent but it will be controlled by spraying of water, whenever necessary. 9. MEASURES FOR PROTECTING HISTORICAL MONUMENTS AND FOR REHABILITATION OF HUMAN SETTLEMENT LIKELY TO BE DISTURB DUE TO MINING ACTIVITY There is no human settlement or historical monument in 500 m. radius of the area, therefore proposed mining will not disturb the human settlement or historical monuments. 10. SOCIO-ECONOMIC BENEFITS ARISING OUT OF MINING. There will be positive effect to some extent on socio-economic environment of the area as mining activity will assure job continuity of already engaged people also it may cause further job opportunities for additional people, which ultimately will improve the financial status of the local people.
