Boss Energy Limited (ASX: BOE; OTCQX: BQSSF) ) is pleased to provide an update on the strong progress being made as part of the commissioning and production ramp up at its Honeymoon Uranium Mine.

Highlights

Operations

First NIMCIX production column achieves nameplate uranium productionA total of 72,516lbs of uranium produced in the months of July and AugustPreliminary updates on costs to be provided once the second and third IX circuits (NIMCIX columns) are commissioned

Construction

Boss Managing Director Duncan Craib said: “We continue to meet or exceed all of our key targets and are comfortably on track to meet our production guidance.

“The first IX circuit is now operating at nameplate capacity, proving that the technology works at the rate and scale forecast in the Feasibility Study. This is a pivotal point in the project’s development. “Commissioning of the second IX circuit is underway and construction of the third is advancing rapidly.

“Supplies of the pregnant leach solution, grades and extraction rates are meeting or exceeding our targets and overall uranium production rates are rising in line with the schedules in the Feasibility Study”.

Honeymoon Production Results for months of July and August 2024

On 22 April 2024, the Company was pleased to announce a major milestone with production of the first drum of uranium at its 100 per cent-owned Honeymoon Uranium Project in South Australia.

As expected, and in-line with Feasibility Study forecasts, Honeymoon’s production continues to increase as set out in the results for the combined months of July and August 2024.

In August 2024, NIMCIX column 1 achieved nameplate production.

Bringing each new NIMCIX production column online will result in a proportional increase in production and lower the cost per pound produced.

Notes: (1) Conversions: There are 1,000 litres per m3 and 0.0000022 lbs per mg. (2) The weighted average is calculated based on total flow for the quarter.

Plant recovery continues to improve with production optimisation. The variance between IX Production and U308 drummed is due to a build-up of inventory in circuit as well as losses from the circuit. During commissioning and ramp up, losses from the precipitation and dewatering circuits were higher than design which has been a focus for the operations team over the previous month. Losses have been reduced to circa 3.5% in August as improvements were, and continue to be, implemented.

It is important to note that while the tenors being achieved from initial wellfields exceed the average LOM tenors forecast in the Feasibility Study1, the project is still in the ramp-up phase and therefore these tenors should not be extrapolated across the LOM. Boss’ production guidance remains based on the forecast tenors contained in the Feasibility Study.

Given the time taken to ramp-up wellfields in ISR projects, preliminary cost updates will be provided once columns 2 and 3 are commissioned.

Since acquiring Honeymoon in December 2015, Boss has invested significant time and capital in making technical improvements to the project. Boss has now been able demonstrate that the first NIMCIX column can operate at nameplate uranium production which adds confidence that the Company will meet its FY25 production target of 850,000 lbs of U308 as set out in Feasibility Study.
