National Aluminium Co Ltd shares rose up as much as 3.71 per cent to Rs 62.95, their highest since January 16.

The Standing Linkage Committee of the Ministry of Coal has recommended a three-year extension of bridge coal linkage for the company, according to a report.

The coal linkage is recommended by the committee considering the projected delays in captive mining from Nalco's Utkal-D and Utkal-E coal blocks, the report stated.

The stock has posted its biggest intra-day gain in six weeks. The stock was down 7.75 per cent this year as of its last close.
