Shares of Vedanta-owned Hindustan Zinc rose as much as 4% to a day's high of Rs 595.30 on Friday, extending gains for a second straight session and taking the two-day advance to 7%.
The gains came after silver prices rose for a third straight session. MCX silver jumped Rs 13,000 per kg to Rs 2,45,158, supported by a weaker dollar and efforts by the U.S. Treasury Department to keep longer-term yields under control. The U.S. dollar was headed for a weekly decline, making dollar-priced commodities more affordable for holders of other currencies.
