Geological Survey of Bangladesh has found reserve of white clay used to make ceramic products and tiles at Panchbibi pf of Joypurhat, where it earlier found limestone.
"After digging, we found a 60-foot thick reserve of white clay spread over around 100 square kilometres 1700 feet to 1760 feet below the surface," GSB Director General Munira Akhtar told bdnews24.com on Friday.
It was also confirmed that the layer of limestone is 36 feet thick. The layer of white clay was found some 170 feet below the layer of limestone, Akhtar said.
White clay is used to make ceramic products and tiles, she added.
Drilling at Panchbibi was officially called off on Thursday as nothing but parent rock was found after going 1,790 feet down. Generally, no mineral is found after the layer of parent rock.
However, though GSB hoped that coal would be found under the layer of limestone at Panchbibi, now there is no possibility of finding coal there.
"The reserve of white clay is just beneath the layer of limestone. We assumed that the thickness of the layer [of limestone] would be 100 feet. However, we've got 36 feet and it is good," Akhtar said.
GSB had found the layer of limestone, which is 12 kilometres long and eight kilometres wide, by digging 1,494 feet on Jun 2.
GSB Assistant Director and the chief of the team working at Panchbibi, Muhammad Masum: "We've found that the layer of limestone is 36-feet thick and it is situated from 1,494 feet to 1,530 feet below the surface.
"There are shale, clay and sandstone from 1,530 feet to 1,700 feet," he added.
According to him, the layer from 1,760 feet to 1,790 feet is weather zone and the layer from 1,790 feet to 1,815 feet is of parent rock.
Director General Akhtar said four wells would be dug to know the accurate size of the reserves of limestone and white clay.
"Then we will be able to judge whether or not lifting limestone and white clay from the layers will be profitable," she said and added it would take at least two years to finish the job.
"We usually dig only in dry season (November to May). You can't dig when the rainy season starts."
The GSB had started digging at Agair village of Aima Rasulpur Union Parishad of Panchbibi Sadar Upazila in April.
Limestone reserves had also been found at Jamalganj of Joypurhat and Tekerghat of Sunamganj. But the projects to lift limestone from the places were not profitable.
White clay was found in Netrakona and Sherpur but it is barely used to make local ceramic products.
Director of the project at Panchbibi, Mohammad Nehal Uddin said the Tk 59.6-million project started in July 2011 and was expected to end in Jun 2014.
