Mica Reserves by Country (Sheet)
India has reported 110,000 metric tons of sheet mica reserves throughout the eight-year series, while China first reported 75,000 in 2023 and has repeated it ever since. USGS Mineral Commodity Summaries 2019-2026 provide the underlying figures, which capture sheet mica reserves in metric tons. Reserves reflect what could economically be extracted, rather than what was mined in a given year. Listed reserves totaled 185,000 metric tons in 2025.
India holds 110,000 metric tons against China's 75,000 — a split of roughly three-fifths to two-fifths. The 35,000 gap between them is smaller than either figure. Neither country's figure has changed — India's throughout all eight years shown, and China's since 2023. India's 110,000 metric tons appear unchanged in all eight years shown. Nothing in the table moved between 2024 and 2025, and nothing in India's series has ever moved at all. China first appears in 2023 with 75,000 metric tons and has reported the same figure in 2024 and 2025. Its entry changed the table from a single-country series to two reporters, with India accounting for three-fifths of the listed total. Figures come from the USGS Mineral Commodity Summaries 2019-2026. The 2025 reserve figures are those reported in the 2026 edition. Units are metric tons of sheet mica, exactly as reported. This page measures sheet mica; scrap and flake mica is published as a separate series and the two are not interchangeable. Blank entries indicate that the source reported no value; they are not zeroes. No world total is published for sheet mica in the 2026 edition, so shares are computed against the sum of the listed countries. Reserves and production are different measures and should not be combined without equalizing units.

Methodology
Frequently Asked Questions
What are sheet mica reserves?
Sheet mica reserves are estimated quantities of sheet mica that can be economically extracted under applicable conditions, in metric tons. Production measures the amount mined in a year.
Which countries hold sheet mica reserves?
India (110,000 metric tons) and China (75,000) are the only reporters, with India holding about 59.5% of the listed 2025 total.
When did China first report?
China first appears with 75,000 metric tons in 2023 and has held that figure since.
How stable have sheet mica reserves been?
India has reported 110,000 metric tons throughout the eight-year series, while China's 75,000-metric-ton figure has been unchanged since its first report in 2023.
Is there a world total?
No — USGS publishes no world total for this series.
