Pohara Sillimanite Mine (Garpendari Hill East)
 
MSMC’s Pohara Sillimanite Mine (Garpendri Hill East) in Bhandara District is also producing aluminous ores, namely Sillimanite, Quartzite and Pyrophyllite.
The details of mine are as under :

Mineral : Sillimanite, Quartzite and Pyrophyllite.
Village : Pohara
Tahsil : Lakhani
District : Bhandara
Nearest Rly. Station : Bhandara Road(40kms.from Mine)
Monthly Production :  
Reserve : 0.0375 Million Tonnes of Sillimanite.
Period of Lease : 20 Years.
Date of expiry of Lease : Applied for renewal of lease period.
Total Lease hold Area : 31.35 Hect.
 
Presently the mine is not in operation, but the production will start very soon.
 
GEOLOGY
The area lies in toposheet No. 55 O/16 survey of India, at latitude North between 210 01’30” to 21002’55” and longitude between 790 51’28” and 790 51’45” east and is situated about 800 M Due east of Pohara village.

Sillimanite is the main mineral occurring in the area. The ore-body exists in isolated patches lensoid shape, encased with pyrophyllite. Corundum is also associated with Sillimanite and the former is present within the Sillimanite ore-body in very small sporadic patches. Regionally the rock formation encountered in the area belongs to south-western part of the Sakoli synclinorium consisting of Sakoli series rocks of Archean group. The area is exposed in large triangular outcrop, and is also known as Bhandara triangle, the types representing Sakoli series are Phyllite quartz-muscovite-schist,quartz-chlorite-schist,quartzite,quartz-kyanite,sillimanite-pyrophyllite-schist,amphibolite-schist.

The geological sequence of the area is as follows :

Recent : Soil and alluvium
Un-confirmity
Quartz vein

Post Sakoli : Pegmatite & Amphibolites
Un-confirmity
Phyllite ,quartz-mica-schist

Sakoli : Chlorite-Mica-Schist and quartzite
Hornblend-Schist
Quartz-Kyanite, Sillimanite-Pyrophyllite-Schist
 
STRUCTURE
The ore-body trends NNE-SSW and has steep dip varying from 600 to 700 towards west. The rocks are highly jointed. Oblique- joints and bedding joints are prominently visible. Corundum is sporadically associated with Sillimanite and both the minerals are encased with Pyrophyllite in form of isolated lensoied bodies.
