Kathleen Valley: a lithium operation in Australia
Kathleen Valley is a spodumene mine producing lithium in the Goldfields region, Western Australia, operated by Liontown Resources. The sources report 391,992 dmt spodumene concentrate produced for FY2026 (Jul 2025 to Jun 2026); the basis is the whole operation. In lithium content, whole-operation output for FY2026 is about 9,300 tonnes (derived here, not printed by the source): about 3.2% of world lithium output in 2025 and about 10% of Australia's; it is one of 8 operations on this site whose output can be stated in lithium content.

How the lithium-content figure is worked out. 391,992 dry tonnes of concentrate produced, at 5.1% lithium oxide (the average grade of the concentrate sold, as the annual report states), times 0.4646, is about 9,300 tonnes of lithium. The grade is that of sales, not of production, so the result is approximate. World mine production of lithium in 2025 was 290,000 tonnes (USGS Mineral Commodity Summaries 2026); Australia produced 92,000 tonnes.
The period (FY2026) is not the calendar year of the USGS totals (2025), so the shares are approximate.
Status: operating, as of 31 August 2026.

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 lithium 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 lithium mine. Shares of a country's output mix periods and bases, so treat them as indicative.
