Background and History

The Tropicana discovery was made in 2005 and additional discoveries were made at Havana in 2006 and Boston Shaker in 2010. A Bankable Feasibility Study was completed and development approval received in 2010. Mining commenced in 2012 and first gold was produced in September 2013. In September 2020, commercial production was declared from the Boston Shaker Underground Mine, the first underground operation at Tropicana. In 2022, production commenced at the second underground area, Tropicana. Whilst recently the development of a third underground mine, Havana underground, was approved.

Exploration is targeting additional underground ore sources and new, regional open pit ore sources.

Mining

During FY25, mining activities at Tropicana continued within the Havana open pit and across the Boston Shaker and Tropicana undergrounds.

Ore Resources have grown consistently, resulting in consistent growth in Tropicana underground Ore Reserves since the commencement of underground mining in 2020.

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. While the Tropicana JV controls about 90% of the Archean Plumridge Terrain at the western margin of the Albany Fraser belt.

Across Tropicana, near-mine and regional drilling activities are targeting the identification of new mineralisation and expansions of current Mineral Resources with a number of promising open pit and underground targets.

In FY25, Regis completed over 174 kilometres of drilling during the year, highlighting our commitment to increasing the life of our existing projects.
