Metal and mining giant Vedanta today said its iron ore production in Goa fell 58 per cent to 1.5 MT in March quarter due to lower demand for low grade ore and closure of mining operations in the state.
In Goa, production and sales during the quarter were 1.5 MT(million tonne) and 2.4 MT, respectively, the company said in filing to BSE.
"The production volumes were lower year-on-year primarily due to lower demand for low grade ore and mine closure pursuant to a Supreme Court judgement," it said.
The apex court in an order dated February 7, 2018 directed mining operations in Goa to stop with effect from March 16, 2018.
In Karnataka, the company's iron ore production stood at 0.1 MT.
During the quarter, Vedanta's pig iron production stood at 1,82,000 tonne. Output of copper cathodes grew 3 per cent to 1,06,000 tonne from 1,03,000 tonne in the year-ago quarter.
