OPERATIONS
PRODUCTION, COSTS AND NOTIONAL CASHFLOW
Perseus’s three operating gold mines, Yaouré and Sissingué in Côte d’Ivoire, and Edikan in Ghana, produced a combined
total of 121,237 ounces of gold in Q4 FY25. The weighted average production cost was US$1,038 per ounce, while the
weighted average AISC was US$1,417 per ounce.
In Q4 FY25, combined gold sales from all three operations totalled 131,242 ounces or 13,657 ounces more than in Q3
FY25 due to the timing of shipments. The weighted average realised gold price was US$2,977 per ounce, US$515 per
ounce more than the Q3 FY25 price of US$2,462 per ounce.
Perseus’s average cash margin for the quarter was US$1,5 60 per ounce resulting in notional operating cashflow from all
operations of US$189 million, US$37 million more than in Q3 FY25.
These strong operating results, summarised in Tables 1 to 3 below, confirm Perseus’s position as one of the world’s better
performing mid-tier gold producers.

YAOURÉ GOLD MINE, CÔTE D’IVOIRE
Refer to Table 4 below for details of Yaouré Gold Mine’s operating and financial parameters during Q4 FY25.
During the quarter, Yaouré produced 70,259 ounces of gold, 2% more than the prior quarter, at a production cost of
US$809 per ounce and an AISC of US$1,180 per ounce. In total, 77,750 ounces of gold from Yaouré were sold at a
weighted average sale price of US$3,004 per ounce. This resulted in an average cash margin of US$1,824 per ounce for
the quarter. Notional operating cashflow generated by Yaouré during the quarter was US$128 million, compared with
US$99 million in Q3 FY25
Mill throughput averaged 509 tph, slightly below the prior quarter’s 514 tph, due to increased high-grade fresh ore blend
added in May and June 2025. Mill run-time was 93.8%, compared to 95.3% previously.
Operating performance at Yaouré improved in Q4 FY25 relative to the prior quarter. Gold production was up 2%, driven
by a 4% increase in head grade, with gold recovery remaining comparable to the prior quarter.
Yaouré saw a modest increase in each of its unit costs during the quarter, most notably in relation to royalties and
sustaining capital. The increase in royalties is a result of the heightened gold price sustained over the duration of the
quarter, whil st the increase in sustaining capital primarily relates to ongoing works on the tailings storage facility
expansion. Although the gold price has increased royalties, it has also had a positive impact on the average realised sales
price, which increased 24% fro m the prior quarter. This has led to an increase in cash margin and notional cash flow of
27% and 30% respectively.

MINERAL RESOURCE TO MILL RECONCILIATION
Table 5 shows the reconciliation of processed ore tonnes, grade and contained gold relative to the Yaouré Mineral
Resource Estimate (MRE).
In Q4 FY25, tonnes processed at Yaouré were 25% higher than predicted, while the head grade was 15% lower, resulting
in contained g old being 6% above the MRE prediction . This represents an improvement against the Q3 2024 reported
results. Although mined grades remained below expectation, higher tonnage continues to offset this divergence, allowing
the site to maintain a positive metal variance. Over the six and 12 -month periods, the same pattern has
persisted. Reconciliation performance in the CMA pit is largely attributed to edge effects associated with blasting and
mining of the final benches of the open pit where mining expected to finish in Q1 FY26. At the Yaouré pit, the current
reconciliation performance remains outside of acceptable ranges, however work progressed during the quarter on a
range of measures to improve grade reliability, including the implementation of an updated grade control methodology
suitable for the differences in structura l setting seen within the Yaour é deposit. As these measures continue to be
implemented across site, improvements in reconciliation performance are expected.

EDIKAN GOLD MINE, GHANA
Table 6 below summarises the key operating and financial parameters recorded at the Edikan Gold Mine during Q4 FY25
and in relevant prior periods.
Edikan produced 38,865 ounces of gold at a production cost of US$1,060 per ounce and an AISC of US$1,482 per ounce
during the quarter. Edikan’s production was down and AISC was up compared to the previous quarter ( -7% and 26%
respectively). Gold sales of 4 2,033 ounces were 4% higher than in the prior quarter at a weighted average realised gold
price of US$2,932 per ounce. This was US$381 more than in the prior quarter, generating an average cash margin of
US$1,451 per ounce. Notional cashflow of US$56 million was generated by Edikan during the quarter, 2% less than in Q3
FY25.
During the quarter, the head grade of processed ore was 0.86 g/t, down from 0.95 g/t; throughput averaged 794 tph,
slightly lower than 800 tph; gold recovery was 87.9%, down from 88.3%; and mill run-time was 93%, compared to 9 0%
previously.
AISC for the quarter was US$1,482 per ounce, US$305 per ounce higher than the previous quarter. This increase reflects
the transition from the AG and Fetish pits to the Nkosuo pit, resulting in a higher strip ratio during early-stage mining and
lower recovery from processing oxide material rather than fresh ore that was mined in AG and Fetish. Delays in ramping
up Nkosuo due to wet weather required processing of lower grade stockpiles, further impacting head grade and gold
production.
Mining at the Nkosuo deposit, was also constrained by limited access to parts of the designated mining area. Negotiations
for land access and compensation for affected landowners and farmers have progressed more slowly than planned .
Subsequent to the end of the quarter, the Ghanaian government has intervened in the dispute with landowners, and a
resolution is considered imminent which will allow Perseus full access to the deposit and enable mining of higher-grade
material than was available during the quarter.
During the quarter, the current phase of Fetish Pit was completed, and equipment reassigned to Nkosuo. Finalisation of
mining in the AG Pit was prevented by wet weather during the quarter, but this is expected to occur shortly . Plans are
now being developed for a further cutback of the Fetish pit and the Esuajah North Pit in future periods.
MINERAL RESOURCE TO MILL RECONCILIATION
Table 7 shows the reconciliation of processed ore tonnes, grade and contained gold relative to the Edikan MRE.
In Q4 FY25, ore tonnes processed were 10% greater than predicted, with a 11% reduction in head grade, resulting in
slightly lower (2%) contained gold. This is attributed to mining constraints at the bottom of the Fetish pit, and interactions
with historical artisanal workings in the Nkosuo pit. While the six-month performance is affected by lower grades ( -8%),
the 12 -month performance remains within an acceptable range with block model estimates achieving actual milled
grades.

Mine, and mining operations at the Fimbiasso East and West pits located on the Fimbiasso Exploitation Permit, some 40
kilometres from the Sissingué processing facilities.
7
NEWS RELEASE | JUNE 2025 QUARTER REPORT
PERSEUSMINING.COM
The Complex produced 12,113 ounces of gold during the quarter at a weighted average AISC of US$2,5 84 per ounce.
Compared to the previous quarter, gold production increased 9% while AISC decreased 6%. The improved performance
was primarily due to an improvement in head grade, which averaged 1.12 g/t compared to 1.03 g/t in Q3. A portion of
the Airport West pit was mined for high -grade oxide ore, while waste stripping progressed at Fimbiasso West and
Sissingué Stage 4 to access higher grade ore.
Mill runtime at 9 6% was up from previous quarter 94%. Throughput averaged 180 tph, below the 188 tph achieved in
Q3, primarily due to a higher proportion of fresh ore in the blend. Gold recovery improved marginally to 88.3%, from
87.4% in Q3.
The improved operating performance in Q4 FY25 has resulted in a cash margin of US$3 72 per ounce, resulting in a
notional cashflow of approximately US$5 million for the quarter.

MINERAL RESOURCE TO MILL RECONCILIATION
Table 9 shows the reconciliation of processed ore tonnes, grade and contained gold relative to the Sissingu é MRE.
In Q4 FY25, tonnes mined at Sissingué exceeded MRE predictions by 11%, while the head grade was 21% lower than
predicted. This resulted in a 13% reduction in contained gold compared to the prediction. The positive tonnage variance
was driven by two factors, the first being the continued discovery of additional material through grade control drilling at
the Sissingué Main pit, and the second being the increased dilution associated with mining of narrow structures at each
of Sissingué Main and Fimbiasso West.
Both factors contribute to the lower grades reported as compared to the block model estimates. Continuous monitoring
of blast performance and improvement initiatives are in place to minimise dilution in these mining areas. Over the longer
six- and 12-month periods, ore tonnes consistently exceeded the prediction, while head grade remained slightly below
expectations. Perseus considers this outcome to be in line with operational expectations.

BAGOÉ EXPLOITATION PERMIT
During the quarter, negotiations continued with various departments of the Ivorian Government on the terms of the
Mining Convention to govern the development and operation of mining operations on the Bagoé Mining Licence that
was granted in June 2024. The negotiations have progressed but at a much slower rate than desirable and signing of the
Convention is expected to occur once all formalities are completed, either in late Q1 FY26 or early the following quarter.
Mining operations are scheduled to commence at the Antoinette deposit in Q2 FY26 and progressively move to the
Veronique pit in subsequent periods. Work is currently underway to prepare for the construction of infrastructure
required to support the Bagoé mining operation. Several tenders were issued this quarter, including fuel supply and ore
haulage. Major contract awards are expected to be finalised in early Q1 FY26. The Grade control drilling also commenced
at Antoinette, and early in -pit boreholes will be drilled in Q1 FY26 to assist with wall stability and mining conditions,
particularly during future wet seasons.
FIVE-YEAR GOLD PRODUCTION OUTLOOK
During the quarter, Perseus published its Five-Year Operating Outlook for the period from FY26 to FY30 . The outlook
included forecasts of both gold production and AISC for its producing mines located in Ghana, Côte d’Ivoire and the soon
to be completed Nyanzaga Gold Mine in Tanzania. The outlook is based on planning assumptions that reflect current
operating conditions at each of the existing mines and employs operating assumption that underpinned FID for the CMA
underground mining operation at the Yaour é Gold Mine in Côte d’Ivoire (see ASX announcement “Perseus Mining takes
Final Investment Decision on CMA underground project at Yaouré ” dated 28 January 2025 ), as well as the development
of the Nyanzaga Gold Project (NGP) in Tanzania (see ASX announcement “Perseus Mining proceeds with development of
the Nyanzaga Gold Project” dated 28 April 2025).
Perseus forecasts producing between 2.6 – 2.7 million ounces of gold during the five -year period, with average annual
gold production in the range of 515,000 – 535,000 ounces. The weighted average AISC over the five-year period is forecast
to be US$1,400 – US$1,500 per ounce, with no more than ±10% change year -on-year over the period, emphasising the
benefit of our portfolio approach to asset management.
