Equipment
Ore is hauled underground via an automated train system to crushing, storage, and hoisting facilities.
Expansion
BHP is advancing a series of growth projects at Olympic Dam. A new decline to the Southern Mine Area is progressing, with completion expected in FY2028, which is anticipated to unlock up to 2.5 million tonnes per annum of additional vertical capacity. The company is also studying a potential Smelter and Refinery Expansion (SRE). A potential Final Investment Decision is on track for the 2027 calendar year. The first phase would increase concentrate smelting capacity to between 1,100 and 1,400 ktpa.

Beverley North Uranium Mine

Uranium
Opened
2011-01-01
Overview
The Beverley North Uranium Mine is an in-situ recovery (ISR) uranium mine in South Australia, approximately 550 km north of Adelaide. Owned and operated by Heathgate Resources Pty Ltd, a subsidiary of General Atomics, it commenced production in 2011. Currently on care and maintenance due to market conditions, its infrastructure supports processing for the nearby Four Mile Uranium Mine.
Production
Due to the "care and maintenance" status, there has been no recent production from the Beverley North mine itself. Heathgate Resources files consolidated annual compliance reports for the Beverley, Beverley North, and Four Mile mines, which does not provide separate production figures for each mine.
Processing
The Beverley North mine was designed to have its ore processed through the main Beverley facility. The in-situ recovery process involves pumping a solution containing oxygen and a weak acid through the orebody to dissolve the uranium minerals. The uranium-rich solution is then pumped to the surface and loaded onto resin at a satellite plant before being transported for final processing.

Overview
The Beverley Uranium Mine, located in South Australia, is Australia's first operating in-situ recovery (ISR) mine. It commenced production in late 2000. Currently, the Beverley mine is on care and maintenance, with its processing plant being used to process uranium from the nearby Four Mile mine, which is also operated by Heathgate. The mine's infrastructure includes a processing plant, two satellite plants, a power plant, an airstrip, and camp accommodation for 180 people. Heathgate Resources has invested over $2 billion in mine infrastructure and plant across its operations. The company holds permits for ISR uranium in the Frome Basin and actively explores for more deposits, which offer the potential to extend operations at Beverley.
Production
Production overview - 2020: uranium 0 t; 2019: uranium 0 t.
Processing
The Beverley processing plant is now solely used to process ore from the Four Mile Uranium Mine. Ore is processed into uranium oxide concentrate (UOC), commonly termed yellowcake, and exported in powder form. The process involves extracting uranium from the mining solution using ion-exchange.

Overview
The Coronel Oviedo Project is an exploration-stage uranium project in central Paraguay, covering over 223,000 acres. It has a geological setting similar to the South Texas uranium belt. UEC conducted drilling in 2012 and has an Exploration Target of 23-56 million pounds grading 0.040%-0.052% U3O8. As of early 2025, UEC is appealing the Paraguayan Ministry of Public Works and Communications' (MOPC) position regarding the extension of concessions.
Processing
Preliminary studies and aquifer tests indicate the project is amenable to in-situ recovery (ISR) methods. The aquifer properties are reported to be within the range of values for other uranium ISR projects in Wyoming, Texas, and Nebraska.
Equipment
UEC owns equipment for radon gas and surface gamma surveys.

The Kiggavik project is a uranium project located in the Kivalliq region of Nunavut, Canada, approximately 80 kilometres west of Baker Lake. It is currently in a care and maintenance phase. In 2015, the Nunavut Impact Review Board (NIRB) recommended against the project due to an indefinite start date, a decision upheld by the federal Minister in 2016. The project was proposed as a combination of open pit and underground mining operations at two main sites: Kiggavik and Sissons, including a mill to process ore into yellowcake.

Overview
The Horseshoe-Raven Project is an advanced exploration stage project owned 100% by Uranium Energy Corp, located in the eastern Athabasca Basin in Saskatchewan, approximately 5 km from Cameco's Rabbit Lake mill. The project has outlined resources and is undergoing resource expansion. It has direct access to all-weather roads and power infrastructure. The uranium mineralisation at the Horseshoe and Raven deposits is hosted in basement rocks with no sandstone cover and is found at depths between 100 m and 450 m below the surface. This suggests the deposits are potentially amenable to development without the need for costly ground freezing.
