The Tropicana Operation is located on the western edge of the Great Victoria Desert, which is the land of Traditional Owners and custodians from the Wongatha and Spinifex peoples. Tropicana is a Joint Venture and IGO holds 30% while AngloGold Ashanti Australia (AGAA) is the operational manager and holds 70%. IGO targeted and pegged the area containing the current ore reserves in 2001. AGAA farmed into the project in 2002, discovering the Tropicana, Havana and Boston Shaker gold deposits in 2005, 2006 and 2010 respectively. The decision to develop the Tropicana Operation was announced in November 2010 following completion of a positive Bankable Feasibility Study. Mining the Havana deposit commenced in 2012 and first gold was produced in September 2013. In January 2018, the Tropicana Operation achieved its two-million-ounce milestone. In May 2019, the development of the Boston Shaker Underground commenced. FY19 PRODUCTION For FY19, Tropicana production was within guidance range achieving 518,172oz Au (100% basis) or 155,452oz Au (IGO 30% share basis), while FY19 gold refined and sold was 154,402oz Au (IGO 30% share basis). Since 2013, Tropicana has delivered strong free cash flow and remains prospective with further value enhancement opportunities. This includes commencement of production from the Boston Shaker Underground, which is currently in development and expected to achieve first gold in the September 2020 quarter.
