Honeymoon was shuttered in 2014 due to the low uranium price in the aftermath of the Fukushima nuclear disaster in 2011.
In a statement to the Australian Securities Exchange last year Boss CEO Duncan Craib said the company was just waiting for a stronger price signal to restart operations and was confident market dynamics were moving in the right direction.
With the uranium spot price hovering around $53 per pound Boss is moving through the front-end engineering and design process at the remote mine and expects to start detailed design work and order long-lead items shortly.
Boss recently awarded an engineering, procurement and construction contract to Process E&I, for Honeymoon's electrical, instrumentation and control system.
Under the scope of the contract Process E&I will lead the instrumentation controls and electrical engineering and provide owners' team integration, data management and document control services, to meet the mine's commissioning needs.
The contractor will also handle equipment tendering, procurement and evaluation services.
Boss has also appointed a power infrastructure engineer, structural and tankage design engineer, in-house structural, mechanical and piping designer and an in-house pump and piping engineer, as part of the FEED process.
They will work to finalise the design and final equipment selection in the lead-up to a final investment decision.
Craib said the company was advancing multiple work streams in parallel to minimise the lead time between FID and the start of production.
"We are making project preparations on several fronts to ensure we can capitalise on the rapidly turning uranium market at the moment of our choosing," he said.
"We are already the most advanced of all the non-producing Australian uranium projects, with a production plant and key infrastructure in place."
Craib said making these preparations ensured Boss was on track to be Australia's next uranium producer."
