Sindesar Khurd: a zinc operation in India

Sindesar Khurd is an underground mine producing zinc in Rajasthan, India, operated by Hindustan Zinc. The sources report 148 thousand tonnes of zinc mined metal ('000 tonnes) for FY2026 (1 April 2025 to 31 March 2026); the basis is whole mine, as reported by Hindustan Zinc. In zinc content, whole-operation output for FY2026 (1 April 2025 to 31 March 2026) is 148,000 tonnes: about 1.1% of world zinc output in 2025 and about 17% of India's; it is one of 22 operations on this site whose output can be stated in zinc content.

Between FY2025 (1 April 2024 to 31 March 2025) and FY2026 (1 April 2025 to 31 March 2026) the reported figure rose by 10.4%, in the same unit and on the same basis.

How the zinc-content figure is worked out. Hindustan Zinc prints 148 thousand tonnes of zinc mined metal for this mine for FY2026 in its mine table. The table lists the mines it operates, so the figure covers the whole mine. World mine production of zinc in 2025 was 13,000,000 tonnes (USGS Mineral Commodity Summaries 2026); India produced 870,000 tonnes.

The period (FY2026 (1 April 2025 to 31 March 2026)) is not the calendar year of the USGS totals (2025), so the shares are approximate.

Status: operating, as of 31 March 2026.

Hindustan Zinc prints zinc mined metal and lead mined metal as separate columns for each mine; only the zinc column is used here.

Method and limits

Reported, not estimated. Output is the figure the operator or owner published, in the unit it used. This site does not estimate output where none is published.
Shares. A share divides output in zinc content by the USGS world or country total for 2025. Where the operator's year is a fiscal year or the unit is a concentrate or a carbonate equivalent, the share is approximate or not given.
Whole operation or owner's share. The basis column says which. A joint venture's output is never counted twice.
Partial list. Only operations with a published figure are listed, so the rank is among those on this site, not among every zinc mine. Shares of a country's output mix periods and bases, so treat them as indicative.
