1.1.3 Brief Description of the Nature of the Project
The proposed project is for expansion of quantity of Varada Bauxite Mine from 27189TPA to 324430 TPA ROM.
The mine lease is a piece of non-irrigated barren land. Total reserves of 1614265 MT.
In Varada Bauxite Mine the nature of deposit is bedded, mineral bauxite is present in form of bed, which is
overlain by a thin cover of Soil, The proposed project entails open cast semi mechanized mining in the mining
lease of Varada-I & Varada-II. As the mining lease was already worked out therefore on the basis of geological
data gathered from the working pits, trial pits, ore reserve were estimated.
Category wise reserves of Bauxite are summarized in Table 1.1

In proposed plan, mining will be carried out by semi mechanized open cast method withthe use of drilling and
blasting.
1.1.4 Demand-Supply Gap
This is an existing captive mine for supply of high grade material to Orient Abrasive Limited’s Plant located
at Porbandar. The plant is under expansion, the Supply and Demand gap is 40%, and the project clearance
will further reduce the Demand & Supply gap. Hence demand supply issues whilst important, are
considered in the current situation.
1.1.5 Imports v/s Indigenous Production
This is an existing mine for the supply of high grade material to OAL’s plant located at Porbandar and OAL has
not imported high grade material yet.

Life of Mine
Mining will be carried out at a maximum production of 324430 TPA and as per IBM approved Scheme of Mining
the life of mine would be 6 years. Entire lease area leaving statutory barrier will be mined out in 6 years.
Varada-I Mining Lease:
As per estimated Mineable reserves of 474429 MT of Bauxite available with average annual production proposed
of Bauxite is 120000 MT, the balance Mine Life period is 5 years.
Varada-II Mining Lease:
As per estimated Mineable reserves of 772383 MT of Bauxite available with average annual production proposed
of Bauxite is 130000 MT, the balance Mine Life is 6 years.
1.2.6 Conceptual Mining Plan
Ultimate Pit Limit
In the Mining lease area the mineralized limits are determined either by the limit of the mining lease boundary
or by the limits of the ore body. These limits have been duly marked in the geological plan. The life of mine is 6
years. During mine life period entire lease area leaving statutory barrier will be converted into one common pit
and pat of this pit will be backfilled and remaining part will be converted into reservoir. The conceptual plan has
been prepared up to the life of the mine is 6 years only. The lease area of Varada-I will be converted into one
pit having dimension 710 m in length. Width varies from 40m to 290m and average depth will be about 4.4m.
The lease area of Varada-II will be converted into one pit having dimension 1060m in length. Width varies from
20m to 190m and average depth will be about 5.5m.
Stacking of mineral reject and disposal of waste:-
Varada-I Mining Lease:
The backfilling will be done in the area after winning full thickness of bauxite. The OB and waste generated
during scheme period will be back filled in the mined out area in west part of the lease area. The waste generated
during three years mining scheme period will be backfilled in mined out area at the time of generation if self
hence question of its height and spread does not arise. As volume of voids (area to be worked) is much more
than material available for backfilling of backfilling of entire mined out land upto original ground level will not
possible. Therefore waste part of the area will be backfilled and another part of the lease area will be used as
water reservoir.

Mode of Transport
Bauxite will be transported by tractor to stacking and sorting ground. High grade bauxite will be transported by
hired /owned truck to company’s manufacturing unit at Porbandar. Low grade bauxite will be stacked separately.
1.2.11 Resource Optimization / Recycling and Reuse Envisaged in the Project
The following will be done
The mineralized waste generated during the mining period will be backfilled in order to reduce the change
in land cover or topography of the area. This backfilled area will be used for greenbelt development
Complete backfilling is not possible so a part of mine out area will be used as water reservoir and
stored water will be used for watering the plantation and for dust suppression. In addition to this water
stored in mined out pits will be used by farmers and villagers in nearby area thus reducing the ground
water dependency.

Mine will be worked only in day time (8 hr/ day) and around 98 persons will work, therefore the
domestic waste generated will be low and it is possible to recycle. As it doesn’t require electricity
because working will be only in Day time.
1.2.12 Availability of Water its Source and Energy/Power Requirement
Water
For domestic use water will be supplied by the means of tankers from the nearby village.
For greenbelt development and dust suppression water stored in mined out pits will be used.
For domestic purpose: 3.815 KLD
For dust suppression: 44 KLD
For plantation: 1.05 KLD
Fuel/Power Requirement
The mine will be worked during an eight hours shift i.e. during day time only and hence no electricity is required
for lighting. Diesel, ~3 lit/hr will be used as fuel for running pump for dewatering in rainy season that too for
some time.
2.2.13 Waste Generation and Management
Nature of Waste & Rate of yearly generation
In the proposed mining scheme the OB is likely to be generated during scheme period will be Soil and will be

Selection of Dumping Site
In the proposed mining scheme, it is proposed that waste generated during scheme period will be backfilled in
the mined out area west part of Varada-I mining lease area & east part of Varada-II mining lease area
simultaneously and soil will be spread on backfilled area. Part of mined out land will be used as water reservoir. Method of Dumping & Maximum Height and Spread of dumps
Varada-I Mining Lease:
The backfilling will be done in the area after winning full thickness of bauxite. The OB and waste generated
during scheme period will be back filled in the mined out area in west part of the lease area. The waste generated
during three years mining scheme period will be backfilled in mined out area at the time of generation if self
hence question of its height and spread does not arise. As volume of voids (area to be worked) is much more
than material available for backfilling of backfilling of entire mined out land upto original ground level will not
possible. Therefore waste part of the area will be backfilled and another part of the lease area will be used as

Estimated cost of the project would be around Rs. 68.42 lacs only. This cost includes the project expenditure
towards the laterite and bauxite mine. The mine has been sanctioned by the Government for captive consumption
only and not for sale of products; hence the profitability factor does not arise at this stage. The cost break-up is
given in Table 1.27.

2.8.1 Financial and Social Benefits with Special Emphasis on the Benefit to the Local People
including Tribal Population, if any, in the Area
Critical analysis of the existing socio-economic profile of the area vis-à-vis its scenario with proposed
project activities identifies the following:
About 98 miners will be engaged in mining activities for the project and about 60 people for ancillary
activities.
The proposed activities shall generate indirect employment in the region due to the requirement of
workers in supply auxiliary such as higher machinery service and Ore Transport service afford from the
ancillary works, which would marginally improve the economic status of the people.
Further the additional benefits from the downstream units such as iron industry, steel industry, cement
plant, and metallurgical industry also add value to the society.
