2. Introduction of the project:

2.1. Identification of Project and Project proponent:

The Chitradurga schist belt in Chitradurga district hosts economic deposits like Iron,

Manganese, Limestone & Dolomite deposits and mining activities are being carried out since

decades in this region. There are a number of mining leases operating in this region producing

about 3-5 million TPA of ore deposits for internal consumption and exports. In the years to

come, the demand for the deposits produced will be on the rise both from domestic and export

fronts. In order to meet the growing demand it is inevitable to open up hitherto

unexplored/unused-mineralized zones for systematic development and ore production.

A study conducted in this mining region to integrate environmental concerns with the mining

and related activities sponsored by the Govt. of Karnataka has come up with findings and

suggestions for systematic and scientific mining. It is learnt that this study has voiced the




opinion that with appropriate environmental protection measures this region and stated that

this region can produce 10 to 15 times more than the present level of output.

Sri. T.K.Chandrappa, Mining Engineer, who has vast experience about 42 years in mining has

obtained prospecting license (P.L.No.-3366) for Limestone & Dolomite in Sy. No. 37 & 43 of

Kanubenahalli Village, Hosadurga Taluk, Chitradurga district, Karnataka for a period of 2 years

w.e.f Dated: 13-12-2006. Lease has been renewed for the period of 20 yrs Approval of mine

lease area is attached as Annexure 1.

2.2. Breif Description of nature of the project:

The proposed project involves the mining of limestone and dolomite in an extent of 430 Acers

(174.02 Ha) and it falls in schedule 1(a) (i) Mining of Minerals of Category ‘A’. Approval of

mine lease area is attached as Annexure 1.

2.2.1. Limestone

Based on field observation, Area comprised within the zone of limestone mineralization.

Out crops of Limestone are well exposed all along strike both length & width wise

intermittently with about 0.0 to 0.5m thick soil cover is observed. Apart of these, an old

working, Bore holes, trenches and trail pits justifies depth continuity. Generally, this

Limestone is of sedimentary formation running all along the strike N190 W/ S190 E dip

varies between 200 to 400 East. Limestone found to be compact, hard, homogeneous, fine

grained & concretionary rocks.

2.2.2. Dolomite

Dolomite is a sedimentary rock of carbonate composition and is made up chiefly of a

mineral Dolomite which is CaMg (CO3)2. Applied area comprised of Manganiferrous

quartzite all along ridge surrounded by the Dolomite in the zone of Limestone

mineralization zone. The origin of dolomite has been an incompletely solved problem. It

is believed that deposit might have formed by the replacement of limestone by magnesium-

rich solutions during the intrusion of Manganiferrous quartzite.

2.2.3. Dolomitic Limestone

This is the Mg rich limestone which is the resultant of limestone replaced by magnesium -

rich solutions. At this area, Dolomitic Limestone bifurcates the Limestone and Dolomite.




2.3. Need for the project and its importance to the Country and or Region:

It has recommended opening up new areas in order to reduce the stress/impact on existing

mining leases and this will also lead to exploring the mineral bodies using drilling etc. Proper

exploration of mineral resources will delineate the quality/quantity and help to wrap up at the

most suitable exploitation strategy with an eye on conserving the mineral and reducing waste

handling.

Limestone and Dolomite will be supplied to the steel plant and cement industries located in

Karnataka. Cement grade limestone will be supplied to cement plant after crushing. Material

of -40+10 mm will be sent to steel and cement plant. Fines (-10 mm) will be stacked separately.

This will be sold to fertilizer and other industries as and when required.

2.4. Demand – Supply Gap:

Dolomite is consumed by iron & steel, Ferro-alloys, fertilizer, glass, alloy steel and other

industries. The total consumption of dolomite in 2011-12 was 6.33 million tonnes. It increased

by 1% from that in the year 2010-11, mainly in sponge iron industry. Iron & steel industry was

the major consumer of dolomite in 2011-12 accounting 72%, followed by sponge iron (17%)

and cement & Ferro-alloys (2% each). The remaining quantity was utilised by other industries,

such as alloy steel, glass, fertilizer, paint, refractory, etc.

The limestone resources are classified as per United Nations Framework Classification

(UNFC) system. As per IBM the total cement grade limestone resources is 124,539.551 million

tonnes, out of which the total cement grade limestone reserves is 8948.926 million tonnes

UNFC code (111), (121) and (122), and the total remaining resources is 115,590.625 million

tonnes. The production of the cement by India in the year 2011-12 is 246 million tones falling

short by 22 million tones than the proposed target.

2.5. Domestic and Export Market:

Limestone & Dolomite will be supplied to the Steel plant and Cement industries located in

Karnataka. Cement grade Limestone will be supplied Cement plant after crushing. Material of

-40+10 mm will be sent to Steel & Cement plant. Fines (-10mm) will be stacked separately.




This will be sold to fertilizer and other industries as and when requirement. No exports

envisaged.

2.6. Employment Generation (Direct and Indirect) due to the Project.

The mining project will generate direct & indirect employment. About 99 people will get direct

employment.

5.4. Assessment of Infrastructure Demand

It is obvious to have some of the essential infrastructures to facilitate the employees. For this

purpose it is planned to have office, store, first-aid center, rest shelter.

5.5. Amenities/ Facilities:

All infrastructure facilities such as education, health facilities and other social facilities are

available at district headquarter due to which the proposed site is facilitated with adequacy in

amenities. As most of the workers are employed from the surrounding villages, they would be

using available medical facilities in the nearest primary health center.

6. Proposed Infrastructure:

6.1. Industrial Area:

It is proposed to establish the temporary structures statutory building having the facilities like

Office, first aid center and rest shelter.

6.2. Residential Area.

No Residential Area Proposed. As Skilled and Unskilled Labour drawn from near by villages.




6.3. Green Blet:

Total Unsued land area is 77.3 ha which would be used for Plantation/Afforestation/ Future

expansion. An area of 3.27 ha land has been proposed for the first 5 years plan

afforestation/plantation inside the lease area. Each year around 0.64 ha area will be taken up

for plantation. An average of 1600 saplings will be planted at a spacing of 2 x 2 m per annum.

The species going to be planted are local species as these are having a better chance of survival

in this region.

6.4. Social Infrastructure:

This Project is providing employment to local people directly and indirectly. Indirect

employers are shopkeepers, mechanic, drivers, transporters etc. The lessee will responsible for

providing better social infrastructure benefits such as drinking water, health care measures,

educational facilities, promotion of culture and religious activities in surroundings.

6.5. Connectivity (Traffic and transportation Road/Rail/Metro/Water ways etc)

6.5.1. Availability Of Roads:

All weather road is passing in the applied mining lease through which applied area is

approachable from Kanubenahalli village.

6.5.2. Nearest Railway station:

Ajampura (50km) is the nearest railway station in West.

6.5.3. Nearest Sea Port:

New Mangalore Port, Mangalore (300 km) in West.

6.5.4. Nearest Airport:

Kempegowda International Airport, Bangaluru (220 km) in East.

6.6. Drinking Water Management:

Drinking water for the working men will be met through Water tank mounted on Tractor,

(detachable) and from well near by village.




6.7. Sewerage System:

No proposal for any wet processing of ore using water in the proposed mining area. Hence,

there is no question of effluent generation. Water shall be used only for sprinkling on haul

roads, dust suppression purposes at Screening Plant/loading, afforestation purposes and

domestic use like washing/drinking etc.

The proposed mining activities may add the pollution load to water of seasonal nallahs within

the mining area, in the form of suspended solids, oil/grease etc. by erosion and wash-off etc.

So it is necessary to take appropriate mitigative action to contain the impact on water quality

6.8. Solid Waste Management:

Dolomitic limestone, Manganiferrous quartzite, Banded Ferruginous quartzite, Phyllite /

Schist and Gneisses are the waste material to be handled during mining. A total area of 10.10

ha has been proposed for dumping site. The area selected for dumping is at the western part

of the lease area. These are barren lands. Dumping will be done in 20m height in this mining

plan period. Locations of the proposed dumping sites with each year’s spread

As per the proposed production and development program, 2.10 lakh tons of waste material

generation will be there during 5 years plan period. Maximum height of the dumps shall be

maintained at 20 mtrs with an angle of repose 30 to 35 degrees and spread of dump shall be

around 7300 sqm, in first 5 years.

During the production and development program of 5 years plan period, around 20% will be

subgrade production with an average of 1.18 lakhtons/annum. This material will be sold to

fertilizer and other industries. Stacking of sub-grade mineral shall be done separately on the

designated area systematically and suitable toe-walls will be constructed around the stacks to

prevent wash-off.

A total of 2.93 ha area are located in applied mining lease area has proposed for stacking the

sub-grade minerals. Height of sub-grade mineral stock shall be maintained at 10 mtrs, in two

stages of 5m each with angle of repose 30 to 35 degrees. This will facilitate rehandling the

stocks without any difficulty to process the ore as and when required.The spread of sub-grade

stock shall be around 29300Sqm for the plan period.




6.9. Energy/Power Source:

This Screening plant is proposed to run on the power supply from the DG Set of suitable

capacity, which is proposed to install

7. Rehabilitation and Resettlement (R & R) Plan:

No R & R is required as there is no habitations present in the proposed mining area.

8. Project Schedule and Cost Estimation

8.1. Likely Date of Start and Date of Completion

The mining operations will be started after obtaining all necessary statutory clearances from

the required departments.

8.2. Cost Estimation of the Project

Mineable reserves: 87.69 lakh tons (Limestone is 62.68 lakh tons + Dolomite 25.01 lakh tons)

Nature of Deposit: Limestone and Dolomite Production: First five years:

1.18 lakhs tons/ annum (0.84 lakhs tons of Limestone and 0.34 lakhs tons of Dolomite per annum) Fully developed Production after five years: 1.50 lakh tons/ annum (1.00 lakh tons of Limestone and 0.50 lakh tons of Dolomite per annum)

Capital cost: Rs. 60 Crores (Approx for the mining period of 20 years).




9. Analysis of Proposal.

9.1.1. SOCIO-ECONOMIC BENEFITS

There is positive impact on socio-economics of people living in the villages. The

villages in the buffer zone depend upon agriculture.

Mining operations in the subject area has positive impact by providing Job

opportunities. Besides, there is indirect employment in transportation of deposit to

destinations.

Since the reserves of this area are economically viable, their proper utilization will

improve the economic status of the people nearby.

Lessee will provide required Medical Facility to all the employees at the mines and

medical checkup camps to the local villages, contribution of funds for social and

cultural programs etc.,

Hence, there will be a positive impact on socio-economics of people living in the village
