Suggested Chronology
Unviable explored deposits be exploited by
operating together economically to recover
sunk in cost.
Utilize airborne survey data to locate deposits
<5 mt.
Club the conditional resources in the vicinity
to make sizable Prospects.
A Case Study of unviable explored deposits
Economically operated together:
Ambaji, Deri & Basantgarh,
Pre-Feasibility Study,
Formation of Joint Venture Company,
Feasibility Study by M/s SRK Consultant, USA.
Encouraging Factors
1. Proximity
Ambaji & Deri 4 km apart and Basantgarh 50 km from Ambaji.

5. Infrastructure
a) Land
Use of barren & low cost land
Hilly region to utilized the gravitational flow.
b) Water:
2000m3/d from 1.75 mm3 capacity dam on Taliya Nallah 4.5 km.
away.
c) Power - 7 MW:
Wheeled from 70 MW pit head power plant at Lignite mine,
Nagaur, Rajasthan.
Consistent power supply at a lower cost from Pit head Power
Plant.
d) Approach:
Located on National and State high ways.
e) Township:
Utilized the existing 136 dwellings by addition/ alteration built
during exploration.
f) Communication:
Infrastructure exits
g) Manpower:
Employ local tribals - by imparting skill.
h) Welfare Facilities:
Use educational & medical govt./private available facilities with
project financial support,
Provide drinking water facilities in nearby villages,
Promote small scale industries to generate employment and
prosperity
Recommendation
Efforts should be made for exploiting conditional resources
by clubbing the deposits in vicinities such as:
