How much does it produce?

Reported output of Renison Tin Operation
Period	Output	Basis	Where in the source
CY2025 (12 months to 31 December 2025)	10,748 tonnes of tin-in-concentrate ('Tin produced') 668,422 t of ore processed at 2.01% Sn; mill recovery 79.87%.	100% of Renison (the annual report's production table is headed '100% Basis')	printed p.8 (PDF p.9), Review of Operations, Renison Tin Operation physicals table, row 'Tin produced', 31 Dec 2025 column; text printed p.8 'Renison achieved annual production of 10,748 tonnes of tin-in-concentrate'; Chairman's Letter printed p.3 (PDF p.4) · Metals X Limited
CY2024 (12 months to 31 December 2024)	11,006 tonnes of tin-in-concentrate ('Tin produced')	100% of Renison (the annual report's production table is headed '100% Basis')	printed p.8 (PDF p.9), same row, 31 Dec 2024 column · Metals X Limited
Q3 2026 (quarter ended 30 September 2026)	2,663 tonnes of tin-in-concentrate Metals X's 50% share was 1,332 t; the quarter ended 30 June 2026 was 2,809 t at 100%.	100% of Renison (the annual report's production table is headed '100% Basis')	PDF p.1, Quarterly Highlights, first Renison bullet · Metals X Limited

Between CY2024 (12 months to 31 December 2024) and CY2025 (12 months to 31 December 2025) the reported figure fell by 2.3%, in the same unit and on the same basis.

How the tin-content figure is worked out. Metals X, a 50% participant in the joint venture, reports 10,748 tonnes of tin-in-concentrate produced at Renison in 2025 in a production table headed '100% Basis', so the annual figure is the whole-operation total, not Metals X's 50% share. World mine production of tin in 2025 was 290,000 tonnes (USGS Mineral Commodity Summaries 2026); Australia produced 12,000 tonnes.

Status: operating, as of 30 September 2026.

The annual report describes Renison as an underground tin mine (printed p.7, PDF p.8) located 15 km north-east of Zeehan on Tasmania's west coast (printed p.6, PDF p.7).

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