What Wiluna Mining does
Wiluna Mining Corporation Limited is an Australian gold producer operating the 100%-owned Wiluna Operation at the northern end of the Yilgarn Craton in Western Australia's Northern Goldfields. The asset base consolidates over 1,600 km² of tenement footprint (1,100 km² of active and pending tenements plus gold rights over a further 500 km² under a split commodity agreement with Piper Preston) and a JORC 2012 Mineral Resource of 91.5 Mt at 2.38 g/t for 7.0 Moz of gold, sitting within an 11 Moz system endowment and a Yilgarn Craton total endowment exceeding 380 Moz. The Wiluna Central Mine Area alone contains an underground Mineral Resource of 38.37 Mt at 4.01 g/t for 4.9 Moz and an open pit Mineral Resource of 14.98 Mt at 2.33 g/t for 1.1 Moz. The company was previously listed on the ASX under ticker WMC until its 5 April 2024 delisting and is presently an unlisted public company that has just completed a formal Deed of Company Arrangement restructuring (effectuated 31 December 2025).
The integrated processing platform comprises a 2.1 Mtpa Carbon-in-Leach plant with a gravity circuit, a 750 ktpa flotation concentrator successfully commissioned in December 2021, and a tailings retreatment operation that reprocesses historic tailings at approximately 10 kt per day via 80-tonne excavators and 40-tonne articulated dump trucks feeding the existing CIP circuit. Historically, BIOX® biological oxidation was used to treat refractory sulphide ore from rich sulphide zones more than 60 m below surface, supporting renewed open pit and underground mining from the 1980s onward. The combination of CIL and flotation capability makes the Wiluna facility one of the only regional plants able to process both free-milling and refractory sulphide ores, enabling toll treatment and joint venture processing as a secondary monetisation channel.
Wiluna generates revenue primarily through commodity sales of gold doré (from the gravity circuit and tailings retreatment circuit) and gold concentrate (from the flotation concentrator) to bullion buyers and refineries at prevailing spot/forward prices, with current output of approximately 25-30 koz per annum generating modest cashflow from tailings retreatment. The Wiluna Restart Plan targets staged production growth of ~110 koz per annum (Stage 1) and ultimately ~250 koz per annum (Stage 2) over a three-year period at ~750 kt of ore throughput, positioning Wiluna among the top 15 single-location gold producers in Australia, the US and Canada. A Pre-Feasibility Study at a A$2,880/oz base case gold price confirms a pre-tax NPV8 of A$198.6 million with a 5.5-year payback, against existing infrastructure with an estimated replacement cost of more than A$300 million. The company exited restructuring on 31 December 2025, paid 100 cents in the dollar to all participating creditors by 27 February 2026, appointed a new Managing Director (Victor Rajasooriar, commencing May 2026) and announced a proposed share acquisition linking Wiluna with underground mining contractor Byrnecut on 12 March 2026.
