"Wherever there is double taxation, the government can reduce it till prices are stabilised," Kalavampara suggested.
The office-bearer feels that the imposition of heavy export duty on iron ore is "an attempt to prohibit export of high grade ore".
"Goa traditionally has been exporting low-grade ore. The export duty on low grade ore should be removed," he said.
"Mining in these circumstances is not viable. The prices (of ore) are expected to fall further. Sale of auctioned ore (which was e-auctioned by the state government) is also not possible," said Ambar Timblo, MD of Fomento Resources, a leading mining firm in the state.
Timblo maintained that his firm is planning to restart operations. "But the decision on the actual date will be taken in the next month. So, the exact date of commencement of extraction is unclear at present," he said.
"The company looks at profit after taxes (PAT). Here there will be profit, but no PAT," Sesa Iron Ore's Vice-President, Corporate Affairs Aniruddha Joshi said.
