The Honeymoon uranium project is an advanced in-situ recovery (ISR) project, about 78 kilometres north-west of Broken Hill in South Australia.

Construction began on the $118 project in 2009, 37 years after yellowcake was first found at the site.

The project is currently under construction; with planned technical processes for uranium extraction confirmed following an 18-month demonstration plant operation and field leach trial. Uranium One expected production levels of 880,000 pounds of uranium octaoxide (U3O8) per year.

Honeymoon hosts an indicated resource base of 6.5 million pounds U3O8 contained within 1.2 million tonnes at an average grade of 0.24 per cent. Mineralization extends across an area of 900 metres by 450m at an average depth of 110m. The Honeymoon deposit is recognised as five discrete mineralised sand packages separated by laterally extensive clay seams. The majority of mineralisation identified to date is located near a well-developed structurally controlled bend, associated with a topographic high in the channel floor. The source of Honeymoon's uranium has been derived from both chemical and mechanical weathering of high-level granite located about 2km to the south of the deposit. Sediment fill appears to dominantly derive from mechanically transported granite fragments.

Uranium One planned to pump pregnant leach solution to the surface for processing via the production wells. The process plant would utilise solvent extraction technology to recover uranium from the pregnant leach solution. The uranium product would consist predominantly of uranium peroxide and would be precipitated from aqueous strip solution from solvent extraction. The uranium product would be de-watered and dried prior to packaging for transport.
