Physiogrophy :
The area in general is plain ground having low relief and gentle Southernly slope. The highest and lowest contours of the area are 251 and 231 meters respectively. Almost all the area is covered with black cotton soil of 0.5 to 2.0 m in thickness. The drainage is controlled by the seasonal nallahas passing through South-East and South-West boundry of the leasehold.


The area around Gaurala comprises Limestone & Dolomitic Limestone of Penganga Group of Precambrain age, sandstone and shales of Gondawana group, Clay and sandstone of Lameta group, Deccan lava flows. The Penganga group of rock are the oldest formation in the area and are unconformity overlain by Gondwana sediments, which are in turn over lain by Lametas and Deccan trap formations. The general geological sequences of the area is as under :

Traps (Deccan Lava Flows)-------------------Cretaceous-Eocene

Kamptee shales and Lower Gondwana
Sandstone, and Upper Carboniferous
Barakar Sandstone and to Permian
Talchir Shales
Penganga Group :

Penganga Group of rocks are of Precambrian age. It is oldest formation of the area spread over the area, recognized by Limestone, Dolomite, Shale and sandstone.
a) Limestone
Limestone is the major ore deposit of the area spread over central and North part of the leasehold. Limestone is jet black to grey in colour, fine grained and compact in nature. It occurs in bedded form. The deposit is intermixed with Magnesia Limestone, occurring in the form of small pockets. Veins of calcite can also be seen traversed within Limestone.
b) Dolomite and Dolomitic Limestone :
Occurrence of Dolomite has been reported in Southern part of the leasehold. It is greyish in colour, medium grained, hard and compact in nature. Dolomitic Limestone/high magnesia Limestone occurring along Eastern and western boundary of the Limestone deposit indicates limits of the mineralizes zone (Limestone)
c) Shale:
Shale has been reported to be occurring in Southern part of the area. It is soft in nature, fine grained and purple in colour.
d) Sandstone :
There has been no exposure of sandstone in the area.
The mine is opencast operated by manual means with the aid of compressor and jack Hammer, transport vehicles provided for disposal of waste.
