State-run power generating company NTPC said on Wednesday that it has struck coal at the Pakri Barwadih mines in Jharkhand.
The listed entity said it has "successfully exposed seam-III in its first coal mine-Pakri Barwadih ...after removal of over burden of 7 lakh cubic metre."
The next steps will begin in due course, said NTPC whose share price closed at Rs 163 on the BSE.
"Coal production will commence shortly from this mine and can be supplied to any project of the company. This is a major step towards building assured fuel supply for the company," it said in a statement.
The Indian government has allocated 10 mines with estimated reserves of 7.3 billion tonnes that have a mining capacity of about 107 million tonnes per annum, the statement added.
For the second quarter (Q2) ended September 2016, NTPC's net profit and sales stood at Rs 2,495 crore and Rs 19,398 crore, respectively.
The government of India holds 69.74 percent stake in the company's equity. NTPC has about 22,500 employees and 44 power stations.
Originally a thermal power company, NTPC has forayed into solar and hydro energy in a big way.
