Silver is emerging as a key earnings driver for Hindustan Zinc, with a persistent global supply deficit expected to support prices even as rising production adds to the company’s revenue potential. Analysts see silver prices, alongside zinc realisations and lower production costs, as key factors shaping the company’s earnings outlook. Silver contributed around 28% of Hindustan Zinc’s segment revenue and 43% of segment earnings before interest and tax (EBIT) in the September quarter.
