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

132,419 ounces of gold in Q 2 FY25. The weighted average production cost was US$ 919 per ounce, while the weighted

average AISC was US$1,127 per ounce of gold.

In Q2 FY25, combined gold sales from all three operations totalled 1 36,623 ounces or 27,728 ounces more than in the

September 2024 quarter (Q1 FY25) due to the timing of gold sales. The weighted average gold price realised was US$2,430

per ounce, US$181 per ounce more than the Q1 FY25 price of US$2,249 per ounce.

Perseus’s average cash margin for the quarter was US$1, 303 per ounce resulting in notional operating cashflow from all

operations of US$173 million, US$46 million more than in Q1 FY25.

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 the Q2

FY25 period.

During the quarter, Yaouré produced 66,700 ounces of gold, 18% more than the prior quarter, at a production cost of

US$843 per ounce and an AISC of US$1, 037 per ounce. In total , 69,036 ounces of gold from Yaouré were sold at a

weighted average sale price of US$2,395 per ounce. This gave rise to an average cash margin of US$ 1,358 per ounce for

the quarter. Notional operating cashflow generated by Yaouré during the quarter was US$ 91 million, compared with

US$56 million in Q1 FY25.

For CY2024, Yaouré produced 239,636 ounces of gold, nearly half of Perseus’s total gold production for the period, at an

AISC of US$1,114 per ounce, generating notional cashflows of US$262 million over the 12-month period.

Operating performance at Yaouré has improved in Q 2 FY25 relative to the performance in the prior quarter. Gold

production was up by 18% driven by a 16% increase in the head grade of processed ore ( 1.86 g/t gold to 2.16 g/t gold),

and an improvement in gold recovery of 2% to 93.9%.

As highlighted in Q1 FY25, Yaouré had undertaken an accelerated waste stripping programme designed to recover from

earlier periods, which resulted in a total of 10.6 million tonnes mined and an increase in the mines AISC. As predicted in

the Q1 FY25 Report , there has been a significant decrease in total material mined due to significantly reduced waste

movements and a corresponding decrease in Yaouré’s mining unit costs.

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 Q2 FY25, 30% more ore than predicted by the MRE was processed at Yaouré, however the head grade was 21% lower

than predicted. Overall, this resulted in contained gold being 2% higher than predicted.  For the 6 -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

6-month and 12-month periods. Perseus acknowledges that this performance is outside the industry standard range and

is actively working through the discrepancies to resolve the variances.

EDIKAN GOLD MINE, GHANA

Table 7 below summarises the key operating and financial parameters recorded at the Edikan Gold Mine during Q2 FY25

and in relevant prior periods.

Edikan’s Q 2 FY25 operating performance improved compared with the prior quarter, with 4 8,868 ounces of gold

recovered at a production cost of US$820 per ounce and an AISC of US$1,023 per ounce (compared to 47,766 ounces at

an AISC of US$1,0 21 per ounce in Q 1 FY25). Gold sales of 50,687 ounces was 1 2% higher than in the prior quarter at a

weighted average realised gold price of US$2,509 per ounce. This was US$212 more than in the prior quarter, generating

an average cash margin of US$1,486 per ounce. Notional cashflow of US$73 million was generated by Edikan during the

quarter, 19% more than in Q1 FY25.

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 9 6% compared to 9 1.3% due to a

scheduled maintenance shutdown to replace mill liners in the September quarter, gold recovery was 90.5% compared to

92.0%, the head grade of processed ore was 1.0 1 g/t of gold compared to 1.0 7 g/t of gold, and the throughput rate was

786 tph compared to 750 tph.

Edikan’s AISC was US$ 1,023 per ounce for the quarter, which is in line with last quarter. Improvements this quarter

include a 6% decrease in processing cost per tonne and a 71% decrease in sustaining capital per ounce, offset by an

increase in mining costs per tonne.

For CY2024, Edikan’s production of 193,066 ounces of gold, 38% of Perseus’s total gold production for the period, at an

AISC of US$1,011 per ounce, generated US$239 million of notional cashflow over the 12-month period.

Mining at the recently discovered Nkosuo deposit, located approximately 10 kilometres from the Edikan mill, commenced

during the quarter. All required government approvals for the development are now in place and work on constructing

the access road is nearing completion. Negotiations are progressing for compensation of landowners and farmers who

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

MINERAL RESOURCE TO MILL RECONCILIATION

Table 6 shows the reconciliation of processed ore tonnes, grade and contained gold relative to the Edikan Mineral

Resource Estimate (MRE).

In Q2 FY25, 10% less ore than predicted by the MRE was processed at Edikan while the head grade was 5% higher than

predicted, resulting in contained gold being slightly lower than predicted ( -4%). 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 Q 2 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 Q2 FY25, 16,851 ounces of gold were produced at a weighted average production cost of US$1,509 per ounce and

a weighted average AISC of US$1, 782 per ounce, which was US$161 per ounce higher than the AISC of US$1, 621 per

ounce achieved in Q1 FY25. This increase was driven mainly by 14% lower head grade and a higher strip ratio.

Mill runtime at 94% was higher than the 91% recorded in the last quarter. The previous quarter was impacted by the

August shutdown extending 39 hours longer than planned.

7

NEWS RELEASE | DECEMBER 2024 QUARTER REPORT

PERSEUSMINING.COM

The milled ore throughput rate of 185 tph was higher than the 159 tph recorded last quarter, driven by a lower percentage

of fresh ore in the mill feed blend, coupled with good mill availability. Gold recovery rates were below quarter-on-quarter

(88.6% compared to 92.2%), as was the head grade of ore fed to the mill (1.54 g/t gold compared to 1.80 g/t gold). This

was attributed to the addition of low -grade ore mined at both Fimbiasso and Sissingu é, as well as the increased mill

throughput, which reduced plant residence time and impacted recovery.

For CY2024, the 69,407 ounces of gold produced at Sissingué, 14% of Perseus’s total gold produced during the period,

was produced at an AISC of US$1, 638 per ounce and generated US$ 36 million of notional cashflow over the 12-month

period.

With a weighted average sales price of US$2, 340 per ounce for the quarter, an increase of US$1 51 per ounce relative to

the prior quarter, a cash margin of US$559 per ounce was achieved resulting in notional cashflow for the quarter of US$9

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 3 months, tonnes of ore processed exceeded MRE predictions by 37%, although the head grade was 2%

lower than predicted.  This led to a 34% increase in contained gold compared to the prediction. The positive variance is

a result from additional material discovered through Grade Control drilling at Sissingué Main pit. Over the longer 6-

and 12-month periods, tonnes processed consistently exceeded the prediction while head grade was consistently below

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