Dhaka, April 21: An official of Geological Survey of Bangladesh (GSB) announced the largest ever limestone quarry has been discovered in the northern district of Naogaon.
Nasrul Hamid, state minister for power, energy and mineral resources, came up with the disclosure at a press briefing held at the secretariat on Thursday afternoon.
The quarry is spread over a 50 square kilometre area,the state minister added.
Once commercial production starts, the limestone will cater local demand for clinker – a material used in cement production among other purposes, said the state minister.
It will take another two years to start commercial production.
Bangladesh will not have to import limestone any longer and save Tk 1,000 crore annually, he said.
The GSB will go another 1,500 feet into the ground, said its officials, adding that the reserves at the new field might be five to 10 times of the Joypurhat limestone field, which holds about 100 million tonnes of limestone.
