OPERATIONS

PRODUCTION, COSTS AND NOTIONAL CASHFLOW

Perseus’s three operating gold mines, Yaouré and Sissingué in Côte d’Ivoire, and Edikan in Ghana, produce d a combined

121,290 ounces of gold in Q1 FY25. The weighted average production cost was US$990 per ounce, while the weighted

average AISC was US$1,201 per ounce of gold.

In Q1 FY25, combined gold sales from all three operations totalled 108,895 ounces or 33,035 ounces fewer than in the

June 2024 quarter (Q4 FY24) due to the timing of gold sales. The weighted average gold price realised was US$2,249 per

ounce, US$132 per ounce more than the Q4 FY24 price of US$2,117 per ounce.

Perseus’s average cash margin for the quarter was US$1,048 per ounce resulting in notional operating cashflow from all

operations of US$127 million, US$10 million more than in Q4 FY24.

These strong operating results, summarised in Tables 1 to 3 below, confirm once again Perseus’s position as one of the

world’s better performing mid-tier gold producers.

Figure 1: Growth in gold production at attractive cash margins

YAOURÉ GOLD MINE, CÔTE D’IVOIRE

Refer to Table 4 below for details of operating and financial parameters recorded at the Yaouré Gold Mine during Q1

FY25.

During the quarter, Yaouré produced 56,458 ounces of gold , 2.5% more than the prior quarter , at a production cost of

US$1,025 per ounce and an AISC of US$1,226 per ounce. In total, Perseus sold 46,309 ounces of gold from Yaouré at a

weighted average sale price of US$2,224 per ounce. This gave rise to an average cash margin of US$998 per ounce for

the quarter. Notional operating cashflow generated by Yaouré during the quarter was US$56 million, compared with

US$53 million in Q4 FY24.

In CY2024 to date, Yaouré has produced 172,936 ounces of gold , nearly half of Perseus’s total gold production for the

period, at an AISC of US$1,143 per ounce, generating notional cashflows of US$169 million over the 9 -month period.

Operating performance at Yaouré improved slightly in Q1 FY25 relative to the performance in the prior quarter. Gold

production was up by 2.5% driven by a 4% increase in the head grade of processed ore (1.79 g/t gold to 1.86 g/t gold),

and a small improvement in tonnes per hour throughput rates (470 tph to 488 tph). Mill run-time and gold recovery were

slightly below the prior quarter at 95% and 92.2%.

Significantly, a total of 10.628, million tonnes of waste and ore were moved at Yaouré during the quarter. At 8.578 million

tonnes, w aste movement was 25% higher than in the prior quarter . This reflected an accelerated waste stripping

programme designed to recover from earlier periods, when for a variety of reasons, waste movements fell short of

targets. As predicted in the Q4 FY24 Report, increased waste stripping comes at a cost and Yaouré’s AISC of US$1,226 per

ounce this quarter reflects the elevated waste movements. Going forward planned waste movements significantly reduce

from recent levels and AISC per ounce is expected to decrease accordingly.

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 Q1 FY25, 25% more ore than predicted by the MRE was processed at Yaouré, however the head grade was 17% lower

than predicted. Overall, this resulted in contained gold being 3% higher than predicted. For the six-month and 12-month

periods, tonnes of ore processed was consistently above prediction, while head grade was consistently below prediction.

The higher ore tonnage compensated for lower grades, resulting in overall positive contained gold variance for both the

six-month and twelve-month periods. Perseus views this overall performance as outside of the industry standard range

and is investigating all factors that could be giving rise to the discrepancy.

EDIKAN GOLD MINE, GHANA

Table 6 below summarises the key operating and financial parameters recorded at the Edikan Gold Mine during Q1 FY25

and in relevant prior periods.

Edikan’s Q1 FY25 operating performance was in line with the prior quarter, with 47,766 ounces of gold recovered at a

production cost of US$813 per ounce and an AISC of US$1,021 per ounce (compared to 47,337 ounces at an AISC of

US$1,015 per ounce in Q4 FY24). Gold sales of 45,263 ounces w as 11% lower than in the prior quarter . However, the

weighted average realised gold price of US$2,297 per ounce, US$165 more than in the prior quarter, generated an

average cash margin of US$1,276 per ounce. Notional cashflow of US$61 million was generated by Edikan during the

quarter, 13% more than in Q4 FY24.

Operating performance at Edikan during the quarter was largely in line with targeted key performance indicators and

compared reasonably well to those achieved in the prior quarter . Mill run time was 91.3% compared to 95.0% due to a

scheduled maintenance shutdown to replace mill liners, gold recovery was 92.0% compared to 91.4%, the head grade of

processed ore was 1.07 g/t of gold compared to 1.03 g/t of gold, and the throughput rate was 750 tph compared to 753

tph.

Edikan’s AISC was US$1,021 per ounce for the quarter, US$6 per ounce higher than achieved last quarter. This increase

was driven mainly by a 5.9% increase in mining cost per tonne and a 7.4% increase in processing cost per tonne.

For CY2024 to date, Edikan’s production of 144,199 ounces of gold, 39% of Perseus’s total gold production for the period,

at an AISC of US$1,006 per ounce, generated US$166 million of notional cashflow over the nine-month period.

Preparation work for mining the recently discovered Nkosuo deposit, located approximately 10 kilometres from the

Edikan mill, continued during the quarter. All required government approvals for the development are now in place and

work on constructing the access road is nearing completion. Negotiation of compensation for farmers whose land will be

impacted by the Nkosuo operation has progressed, albeit at a slower rate than was originally planned.

MINERAL RESOURCE TO MILL RECONCILIATION

Table 7 shows the reconciliation of processed ore tonnes, grade and contained gold relative to the Edikan Mineral

Resource Estimate (MRE).

In Q1 FY25, 8% less ore than predicted by the MRE was processed at Edikan while the head grade was 6% higher than

predicted, resulting in contained gold being slightly lower than predicted (-2%). Perseus views this overall performance

as acceptable and in line with the industry standard range.

SISSINGUÉ GOLD COMPLEX, CÔTE D’IVOIRE

Refer to Table 8 below for details of operating and financial performance achieved during Q1 FY25 and relevant prior

periods, at the Sissingué Gold Complex. The Complex includes mining and processing operations at the Sissingué Gold

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.

During Q1 FY25, Perseus produced 17,066 ounces of gold at a weighted average production cost of US$1,374 per ounce

and a weighted average AISC of US$1,621 per ounce, which was US$91 per ounce higher than the AISC of US$1,530 per

ounce achieved in Q4 FY24. This increase was driven mainly by 7% lower gold production, a higher strip ratio, and 10%

fewer ore tonnes processed.

Mill runtime at 91%, was lower than the 93% recorded in the prior quarter, mainly due to the planned August shutdown

extending 39 hours longer than planned.

7

NEWS RELEASE | SEPTEMBER 2024 QUARTER REPORT

PERSEUSMINING.COM

The milled ore throughput rate of 159 tph was below the 175 tph recorded last quarter, driven by a higher percentage of

fresh ore in the mill feed blend. Gold recovery rates were slightly better quarter-on-quarter (92.2% compared to 91.4%),

as was the head grade of ore fed to the mill (1.80 g/t gold compared to 1.76 g/t gold) reflecting the higher grade of

material mined at Fimbiasso.

For CY2024 to date, the 52,555 ounces of gold produced at Sissingué, 14% of Perseus’s total gold produc ed during the

period, was produced at an AISC of US$1,592 per ounce and generated US$28 million of notional cashflow over the nine-

month period.

With a weighted average sales price of US$2,190 per ounce for the quarter , an increase of US$123 per ounce relative to

the prior quarter, a cash margin of US$569 per ounce was achieved resulting in notional cashflow for the quarter of US$10

million.

MINERAL RESOURCE TO MILL RECONCILIATION

The reconciliation of processed ore tonnes, grade and contained ounces relative to the Sissingué Mineral Resource block

model (MRE) is shown in Table 9 below.

In the past three months, tonnes of ore processed exceeded MRE predictions by 2%, although the head grade was 7%

lower than predicted. This led to a 5% reduction in contained gold compared to the prediction. Over the longer six and

twelve-month periods, tonnes processed consistently exceeded the prediction while head grade was consistently below

prediction. Overall, the contained gold has varied between just over and just under prediction over the 12 -month

period. Perseus views this overall performance as acceptable and in line with industry standards.
