Cosmos Nickel Mine
nickel mine in Western Australia
Cosmos Nickel Mine is a currently inactive surface and underground nickel mine 38 km (24 mi) north-north-west of Leinster, Western Australia, along the Goldfields Highway.
The traditional owners of the land the mine is located on are the Tjiwarl people.
History
The Cosmos nickel deposit was discovered in 1997 by Jubilee Gold Mines NL, originally a gold explorer which had switched to nickel exploration the previous year. The Cosmos deposit stood out for its high-grade nickel ore, averaging between five and twelve percent where most other nickel mines in Western Australia operate at a one to three percent grade.
Jubilee Gold planned to invest A$52 million in the project, of which A$38 would go towards the construction of a concentrator. In 1998, the company estimated an initial mine life of three years and a production of 30,000 tonnes of nickel in this time. While mining was initially envisioned to be surface only, an expansion to potential underground mining was announced in the following year.
Mining at Cosmos commenced in 2000 and, in 2004–05, the mine transitioned from a surface to an underground mining operation. In 2007, Jubilee Gold, and thereby the mine, were acquired by Xstrata for A$3.1 billion, at a time when nickel prices had surged. Shortly after the purchase by Xstrata, nickel prices crashed and, in 2012, the mine was placed in care and maintenance.
This brief starts where responsible research should: with the source description of “Cosmos Nickel Mine” as nickel mine in Western Australia. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as nickel mine in Western Australia. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 8, 2026. The linked authority identifier is Q117211815. Authority coordinates are -27.583, 120.573. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1997, 1998, 2000 and 2004.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
