The Production is around 3,000 cbm per annum in mixed sizes which come in Shades of Dark Black and Black Mist. It is a highly mechanized quarry. Its Machinery includes 2 Excavators, 2 Pneumatic Compressors, 2 Dumpers, 1 Derrick Cranes, 1 Hydraulic Drilling Machines, 1 Wire saw Machines, 1 Generators, , 1 Electrical Compressors, Tippers, 2 Slotters, Gensets, Jack Hammers etc. The quarry employs 35 people. The quarry is being operated since 2000. The blocks are majorly exported to several international destinations including China, Italy, Japan etc and few blocks are sold locally.
