Name of the Project
Honeymoon uranium restart project.

Location
South Australia.

Project Owner/s
ASX-listed Boss Energy.

Project Description
An enhanced feasibility study on the project has resulted in a 22.5% increase in production capacity, compared with a 2020 feasibility study on the project.

The project comprises two main exploration areas – the Eastern and Western tenement regions – with one granted Mining Lease 6109, totalling a 2 595 km² tenement package.

The enhanced feasibility study was based on revised capital and operating estimates, a revised wellfield design plan and revised economic assumptions reflecting continued improvement in the outlook

The study is based on using only 36-million pounds of the project’s global Joint Ore Reserves Committee-compliant resource of 71.6-million pounds.

The study proposes the removal of the existing solvent-extraction (SX) plant and replacing it with ion-exchange (IX) capacity. IX will be used as the only uranium-recovery technology in two stages to match the wellfield development schedule.

The startup phase will produce 1.63-million pounds of uranium in Year 2. Works for this phase include replacing the existing SX processing facility with three NIMCIX trains.

Additionally, various modifications will be made to improve performance in the leach liquor, precipitation, drying and packaging circuits to allow for the production of uranium by replacing the existing vacuum dryers with a calciner kiln.

The ramp-up IX circuit will mirror the startup NIMCIX circuit.

In the ramp-up phase, production will increase to 2.45-million pounds a year in Year 3, with the installation of a duplicate IX facility that will operate in parallel with the startup IX facility.

Life-of-mine production has increased from 20.74-million pounds in the 2020 feasibility study to 21.81-million pounds in the enhanced feasibility study.

The project’s mine life has decreased from 12 to 11 years.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The enhanced feasibility study estimates a pretax net present value, at an 8% discount rate, of $308.75-million, an increase of 35%, compared with the 2020 feasibility study.

The forecast internal rate of return is estimated at 47.1%, compared with 51.4% in the 2020 feasibility study.

Payback has decreased from four years in the 2020 feasibility study to 3.5 years in the enhanced feasibility study.

Capital Expenditure
The cost of the project has increased from $69.98-million to $80.01-million.

Planned Start/End Date
Not stated.

Latest Developments
Boss is focusing on progressing offtake negotiations and project financing efforts while advancing the project towards development.

The company is also developing a plan to increase the production profile and extending mine life through the development of satellite resources, and maintaining a strong exploration focus and programme on near-mine and regional targets.
