FY22 PRODUCTION UPDATE
Established Australian copper-gold producer and explorer, Aeris Resources Limited
(ASX: AIS) (Aeris or the Company) is pleased to provide an update on FY22
production and AISC performance at its Tritton Copper Operations and Cracow
Gold Operations.
Tritton Copper Operations:
• FY22 copper production was 18,581t at AISC A$5.10/lb
FY22 copper production guidance: 18,500t – 19,500t @ AISC $4.60/lb - $4.85/lb
Cracow Gold Operations:
• FY22 gold production was 53,920oz @ AISC A$1,911/oz
FY22 gold production guidance: 56koz – 59koz @ AISC $1,775/oz - $1,825/oz
Comments from Aeris’ Executive Chairman, Andre Labuschagne:
“Our turnaround strategy at Tritton continues to deliver with 5,126t of copper
produced in the June quarter, enabling the production guidance to be achieved.
Unfortunately, Cracow again underachieved on its production targets, primarily
due to lower gold grades realised. Despite a challenging operating environment,
including COVID impacts, a tight labour market and inflation related price
increases, there were numerous significant achievements for Aeris in FY22.
Tritton recognized the need to change operating strategy mid-year and has
delivered improved production performance. Life extension (Budgerygar and
Avoca Tank) and exploration projects (Constellation) at Tritton were progressed
during the year and the Golden Plateau deposit at Cracow is an evolving
exploration story that we are quietly excited about.
And let’s not forget the transformational acquisition of Round Oak Minerals, which
means we start FY23 with four operating mines, a long-life development project in
Stockman, strong cash balance and no debt. Our focus is now well and truly on
delivering across our portfolio in FY23.”
Tritton FY22:
During the second quarter of FY22 we recognised that the operating strategy of “fill
the mill” was impacting production targets due to low-grade ore feed from the
Tritton mine. As a result, the Tritton team has implemented changes to the mine
plan, including increased cut-off grade for stope designs and a focus on dilution
control. Over the last 6 months we have seen this updated operating strategy take
effect, resulting in FY22 copper production being within guidance. This new strategy
of focusing on ore “quality over quantity” will accelerate in FY23 with new, highgrade ore sources at Budgerygar and Avoca Tank coming on-line.
AISC was slightly above the top end of our guidance, primarily as a result of cost
and labour market pressures, which are impacting the whole industry, but which we
are working hard to contain. New employment policies to reduce labour turnover
have been introduced and group-wide purchasing initiatives to reduce input costs
are being implemented.
Importantly, we also progressed life extension projects at Tritton during the year to
set the operation up for the future. Drilling continued at the exciting Constellation
deposit with a maiden Mineral Resource declared in December 2021 and an
update planned for the coming weeks. Development of the Budgerygar and
Avoca Tank deposits advanced in FY22 with both mines scheduled to contributed
to production this financial year. As well as improving head grade, these new ore
sources will allow greater production flexibility and reduced variability.
Cracow FY22
Our Cracow Gold Operations had a challenging year. Mined gold grades
underperformed compared to internal targets for FY22 due to the geology models
overestimating grades in areas outside the high-grade core of our Western Vein
Field deposits. Unfortunately, as a result, FY22 production guidance was not
achieved. A significant amount of work has been undertaken to address these
issues, with geological models rebuilt to increase grade confidence and improve
production planning for FY23. Productivity in remanent mining areas was also lower
than anticipated and planning assumptions for these areas have been revised.
The lower FY22 gold production was also the major contributor to the higher than
targeted AISC. In absolute $ terms, opex and sustaining capex were below internal
targets, reflecting a strong focus on cost management by the site team. Like Tritton,
Cracow was also impacted by labour availability and general cost inflation.
In FY22, we continued to focus on life extension opportunities at Cracow and
pleasingly, we have more priority targets now than when the operation was
acquired two years ago. Drilling at the historic Golden Plateau deposit returned
encouraging high-grade drill intersections and a maiden Mineral Resource is
planned for Q1 FY23. Golden Plateau offers the potential for a new, high-grade
production source for Cracow in the near term to offset declining grades in the
Western Vein Field.
