For the $2.98 billion Vedanta deal, the Centre will ask HZL to go for share swaps and warrants.

HZL’s board of directors approved the acquisition of zinc assets from THL Zinc Ventures, a subsidiary of Vedanta Ltd, on January 19.

The Centre may ask Hindustan Zinc Ltd (HZL) to consider alternatives to cash.

Vedanta owns 64.9% of HZL, while the Centre owns the remaining 29.5%.
