Following careful analysis of the mines' historical production
performance under the previous owner, the EFS was focused on building a
more resilient and sustainable mining operation.
The key outcome of the EFS was the decision to remove the existing
Solvent Extraction (SX) plant and replaced it with Ion Exchange (IX)
capacity to increase the production profile to 2.45Mlb/annum over a
+10-year mine life and reduce operating costs to achieve industry
benchmark goals for low-cost producers.
The EFS confirmed this planned change to Honeymoon’s processing plant
would lower costs and increase financial returns, with key outcomes
Based on the parameters outlined in the EFS, Boss’s Board made a
Final Investment Decision to develop the Honeymoon Project in June 2022,
with construction and development programs now proceeding on schedule
to deliver first production in the December Quarter of 2023.
The Project will utilise in-situ recovery (ISR), a proven and
cost-effective extraction process that delivers a range of important
environmental benefits. The ISR process involves the installation of
multiple wells in a specific pattern over the orebody, achieving a
19-28% reduction in energy requirements and producing 17-32% of the
greenhouse emissions of conventional mining. Unlike conventional mining,
ISR also results in minimal, temporary ground disturbance within mining
