Regis holds dominant positions on the Duketon and Albany-Fraser (Tropicana) Greenstone Belts in the North Eastern Goldfields of Western Australia, operating several open pit and underground mines.
Our Mining Operations
-
Duketon
- The Duketon Gold Project is located 130 kilometres north of Laverton and includes surface and underground operations. The project commenced production in 2012 and during 2024 operated across two operating centres:
- Duketon North Operations (Moolart Well)
- Duketon South Operations (Rosemont and Garden Well)
Our operations consist of two main open pit mines and other satellite open pit mines, along with two underground mining areas. At Duketon, we work closely with the Mantjintjarra Ngalia people of this Western Desert region who are the Traditional Owners and custodians of the land.
Our three process plants have a combined nominal capacity of 10Mtpa and employs conventional crushing, grinding and carbon-in-leach recovery methods.
In-line with its strategic underground growth objective of operating 4 to 5 underground mines, targeting annual production of 200koz to 250koz of gold In the future, during 2024, Regis further increased its underground Ore Reserves and announced the establishment of two new underground production areas at Garden Well and Rosemont.

Tropicana
- Tropicana is a Joint Venture (TJV) between AngloGold Ashanti Australia Ltd (70%) and Regis Resources (30%). Since Regis acquired 30% in May 2021, Tropicana has continued to demonstrate Its tier-one potential, delivering 380% growth in underground resources over this time.In 2024, Tropicana operations consisted of two open pits (Tropicana and Havana South) and two underground mines (Boston Shaker and Tropicana). The processing plant has a nominal capacity of 9.5Mtpa (100%) and employs conventional crushing, grinding, and carbon-in-leach recovery methods.The Wongatha and Spinifex peoples are the Traditional Owners and custodians of the land. Sustainability performance for the Tropicana Operation remains a key part of our sustainability reporting for Regis Resources

Our Growth Projects
-
McPhillamys
- Since purchasing the McPhillamys Gold Project in 2012, Regis has invested over $300M in the exploration, scientific studies and design reviews that have informed the planning assessment process. In March 2023 the project was approved by the NSW Independent Planning Commission and the Federal Government, subject to a range of consent conditions.
During FY24, Regis progressed the McPhillamys DFS and in April 2024 an update on key financial metrics was provided. After the end of FY24, the detailed results of the DFS were released outlining the potential for a robust, long-life open pit mine with solid financial metrics. However, on 16 August 2024, the Federal Minster for the Environment and Water announced a Section 10 declaration over a part of McPhillamys, resulting in the loss of access to the planned tailings storage facility (TSF) area. This Section 10 declaration has rendered the Project, in its current form, unviable.
As a consequence of the Section 10 declaration, Regis has withdrawn the Project outcomes of the McPhillamys DFS. This includes taking a non-cash impairment of $192 million against a significant proportion of the carrying value of McPhillamys withdrawing the 1.89Moz of Ore Reserves previously declared with the Project.
Regis is assessing the Section 10 decision and is considering all legal options.

Exploration
- Regis holds one of the largest land-packages within the Western Goldfields, with approximately 3,000 square kilometers of tenements over the Duketon greenstone belt. Regis exploration activities within the Duketon greenstone belt is focused along well established gold bearing trends and includes the prolific the Garden Well trend, which extends from north of Garden Well to south of Tooheys Well and is a trend that Regis has defined 3Moz. The second trend is the Rosemont – Baneygo trend that extends between Rosemont and Baneygo, continuing south past Ben Hur. Exploration activities have focused on the identification and expansion of underground resources, primarily beneath open pits. In parallel, Regis continues to explore surface targets, seeking additional high-value large open pit growth.
In 2023 Regis announced an underground Exploration Target at Garden Well and in 2024, Regis announced that drilling success has defined a new underground production area, Garden Well Main. Furthermore at Rosemont, Regis also announced that drilling success has defined Rosemont Stage 3, an extension to the current Rosemont South underground mining area. Construction of Garden Well Main and Rosemont Stage 3 is currently underway and on track.
At Duketon, the Garden Well South underground mine, achieved commercial production in FY2023.
In early FY25 Regis established an underground exploration target at Ben Hur.The Tropicana Joint Venture (TJV) controls about 90% of the Archean Plumridge Terrain at the western margin of the Albany Fraser belt. At Tropicana, Regis continues to progress its near-mine, underground exploration activities, to successfully upgrading Inferred Resources into Indicated Resources while also extending extends of known mineralisation at depth. Exploration activities have focused on the evaluation of depth extensions of mineralisation at Boston Shaker, Tropicana, Havana and the Cobbler Underground target.
Tropicana continues to hold significant potential for further large-scale open pit discovery and regional exploration activities are working to enhance our current geological understanding while further defining trends that are considered favourable to host mineralisation.
