Its expenses rose to Rs 249.73 crore from Rs 102.58 crore during the quarter under review due to higher provisioning of retirement benefits, royalty and district mineral foundation payments, among others.
"The reduction in annual turnover and consequently, profits is mainly due to oversupply of manganese ore from international market, leading to lower offtake and pressure on selling prices coupled with liquidity crunch at buyers' end," it added.
