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 88, 888 ounces of gold in Q 2 FY26. The weighted average production cost was US$1,363 per ounce, while the

weighted average All-in-Site Cost (AISC) was US$1,800 per ounce. 

The weighted average AISC of US$1,800 per ounce for the quarter was higher than Q1 FY26 restated AISC of US$1, 516

attributable to higher royalties driven by the increased gold price achieved during the period and an additional

2% royalties paid on revenue. Q2 FY26 AISC only includes the additional 2% royalty paid that relates to the quarter. This

additional 2% was paid to the Government of Côte d’Ivoire, despite the stability afforded under the applicable legislation

and the Yaouré and Sissingué conventions with the Government of Côte d’Ivoire. Payment of the additional 2% was done

in good faith as part of ongoing negotiations between the mining industry and the Government of Côte d’Ivoire in relation

to formalising a revised fiscal arrangement which takes into account fair and equitable distribution of profits in the

current high gold price environment. A total of US$20 million was paid in FY26 Q2 in relation to the additional 2% royalty

of which US$4 million related to the December 25 quarter, US$5 million related to the September 25 quarter and US$ 11

million related to the Q3 and Q4 of FY25.

In Q2 FY26, combined gold sales from all three operations totalled 86, 607 ounces or 14,982 ounces less than in Q1 FY26

attributable to lower gold poured. The weighted average realised gold price was US$3,437 per ounce, US$362 per ounce

more than the Q1 FY26 price of US$3,075 per ounce.

Perseus’s average cash margin for the quarter was US$1, 637 per ounce resulting in notional operating cashflow from all

operations of US$145 million, US$11 million lower than in Q1 FY26.

YAOURÉ GOLD MINE, CÔTE D’IVOIRE

Refer to Table 4 below for details of Yaouré Gold Mine’s operating and financial parameters during Q 2 FY26.

During the quarter, total material mined at Yaouré increased by 38% however the ore tonnes mined were lower by 13%

mainly reflective of the increased strip ratio compared to the previous quarter. 32,045 ounces were produced, 42% lower

than the previous quarter mainly due to milled head grade due to unplanned higher reliance on lower grade stockpile

material and the planned switch in ore sources from the CMA open pit to the Yaouré open pit. Gold grade is expected to

improve for the remainder of the year compared to Q2 FY26 as direct feed Yaouré open pit ore increases and the higher

grade CMA UG ore feed commences. As a result, Yaouré underperformed relative to expectation in the quarter.

Ore milled tonnes were lower by 3% mainly due to lower mill -run time compared to Q1 FY26. Mill run-time was 90.1%,

compared to 94.2% for the September quarter mainly from unplanned stoppages due to SAG mill barricade seal failure,

mill splitter box holed and SAG lube changeout (barricade seal related contamination). Mill throughput averaged 455 tph,

slightly above the prior quarter’s 450 tph. Gold recovery was slightly lower at 93.2% compared to 94.0% in last quarter

For the calendar year 2025 (CY2025), Yaouré produced 226,532 ounces of gold, representing 52% of Perseus’s total gold

production for the CY period, at an AISC of US$1,2 86 per ounce, generating notional cashflows of US$358 million over

the 12-month period.

The production cost in the quarter was US$1,574 per ounce with an AISC of US$ 2,092 per ounce (refer explanation on

impact of additional royalties below) . In total, 34,835 ounces of gold from Yaouré were sold at a weighted average sale

price of US$3,243 per ounce. This resulted in an average cash margin of US$ 1,151 per ounce for the quarter. N otional

operating cashflow generated by Yaouré during the quarter was US$37 million, compared with US$98 million in Q1 FY26.

The AISC for Yaouré increased from US$1,110 to US$2,092 per ounce compared to the previous quarter due to expected

decrease in ounces produced, higher royalties and timing related increase in sustaining capital largely as a result of the

timing of the life of mine extension tailings pipeline relocation. As mentioned earlier expected gold production was lower

for the quarter on previous quarter which result ed in higher costs per ounce. Royalties were higher attributable

to increased gold price achieved during the period and an additional 2% royalties paid on reven ue for the full 2025

calendar year. The additional 2% was paid to the Government of Côte d’Ivoire as described earlier.

CMA UNDERGROUND

CMA underground development commenced in Q1 FY26 with the first blast of the Pauline portal. The

other three declines namely Blika, Sika and Assanou commenced during Q2 FY26. A total advance to date of 800 metres

has been achieved across the four portals. CMA Underground will be the first mechanised underground mine in Côte

d’Ivoire hence there is close monitoring of development performance and compliance for the project.

In January 2026 a key milestone was achieved with first ore mined from the Blika Portal. First ore was achieved through

development mining with stoping operations anticipated to commence in Q4 FY26.

practice under IFRS, this cost will be capitalised, and the costs amortised over the remainder of the relevant pit life

3. Royalties, Total All-In Site Cost, Cash Margin and Notional Cash Flow has been restated to include the additional 2% royalty paid in FY26 Q2 but relating

to the respective periods.

4. FY26 Q2 AISC only includes additional 2% royalties paid in Côte d’Ivoire that relate to the December 2025 quarter. The December 2025 half year only

includes the Q1 and Q2 FY26 additional 2% royalty paid. A total of US$17 million was paid in FY26 Q2 of which US$3 million related to the December 25

quarter, US$4 million related to the September 25 quarter and US$10 million related to the Q3 and Q4 of FY25.

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, ore tonnes processed were 27 % higher than predicted, while the head grade was 1 1% lower, resulting in a

13% positive variance in contained gold compared with respect to the resource model estimate. This continues the trend

from the previous quarter, with higher mined tonnage offsetting lower grades, though the overall metal reconciliation

has improved slightly.

Mining continued within the Yaouré pit stages 1&2, where geological variability and dilution continue to impact short-

term grade performance. Despite the lower grades, the 12 -month correlation show contained gold tracking within 5%

of the model, indicating that long-term reconciliation remains stable.

NEWS RELEASE | DECEMBER 2025 QUARTER REPORT

PERSEUSMINING.COM

The on -going implementation of the improved grade control and reconciliation workflows, introduced in late FY25,

continues to enhance confidence in model performance and alignment between mine and mill outcomes

EDIKAN GOLD MINE, GHANA

Table 6 below summarises the key operating and financial parameters recorded at the Edikan Gold Mine during Q2 FY26

and in relevant prior periods.

Edikan produced 38,352 ounces of gold at a production cost of US$1,097 per ounce and an AISC of US$1,535 per ounce

during the quarter. Edikan’s production was up 17% and weighted average AISC was lower by 4% when compared to the

previous quarter. Gold sales of 37,219 ounces were 19% higher than in the prior quarter at a weighted average realised

gold price of US$3,700 per ounce. This was US$363 more than in the prior quarter, generating an average cash margin of

US$2,165 per ounce. Notional cashflow generated was up 46% to US$83 million for the quarter compared to Q1 FY26.

For CY25, Edikan produced 151,741 ounces of gold, representing 35% of Perseus’s total gold production for the calendar

year period, at an AISC of US$1,4 38 per ounce, generating notional cashflows of US$253 million over the 12- month

period.   

Total tonnes mined at Edikan during the quarter lagged production expectations, with low digger availability production

impediment encountered in Q2 FY26. Ore tonnes mined in Q2 FY26 were however 43% higher than Q1 mainly

attributable to higher grade ore access during the period. The full footprint of the Nkosuo pit is now being mined

following previous access constraints, allowing improved efficiency in mining operations. Throughput averaged 896 tph,

higher than prior quarter’s 831 tph with the treatment of more Nkosuo oxides in the feed blend for the quarter; the head

grade of processed ore was 0.77 g/t, up from 0.67 g/t following ramp up of Nkosuo mine operations; gold recovery was

87.9%, marginally higher than the 87.3% achieved in the prior quarter; and mill run -time was 1,966 hours, compared to

2,085 hours for the previous quarter due to lost time from SAG Mill bearing failure in Q2.

AISC for the quarter was US$1,535 per ounce, representing a decrease of US$68 per ounce compared to the

previous quarter. This decrease is primarily due to lower production cost per ounce associated with an increase in ounces

produced driven by higher head grade. In addition, production costs benefited from lower consumption of leaching

and flotation reagents. Lower mined volume in Q2, resulting from low excavator utilisation and wet ground conditions

at Nkosuo further contributed to the lower production cost.

Plans to mine cutbacks of Fetish and Esuajah North pits are currently progressing with a pplications submitted to the

relevant regulators for approval to commence mining at both areas.

MINERAL RESOURCE TO MILL RECONCILIATION

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

For Q2 FY26, the 3-month factors indicate an increase in tonnes (9%), slight lower in grade (-3%), resulting in more metal

content (5%). This represents a notable improvement over Q1 FY26, where the 3 -month correlation factors showed

an under call in tonnes ( -11%) and contained gold (- 16%). The 6 - and 12 -month trends now fall within 5 –6% range,

demonstrating strengthened alignment over time. Operational controls, including regula r floor maintenance and

sheeting of muddy areas at Nkosuo pit were put in place to further tighten reconciliation and support continued

convergence between the Reserves and mill outcomes.

SISSINGUÉ GOLD COMPLEX, CÔTE D’IVOIRE

Refer to Table 8 below for details of operating and financial performance achieved during Q 2 FY26 and relevant prior

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

Mine, together with satellite mining operations comprising the Fimbiasso Gold Mine, located approximately 65

kilometres from the Sissingué processing facilities, and the newly dev eloped Bagoé Gold Project, located approximately

137 kilometres from the Sissingué processing facilities. Mining at Bagoé commenced during the quarter at the Antoinette

Deposit, following the completion of mining operations at Fimbiasso.

For CY2025, Sissingué produced 53,411 ounces of gold, representing 12% of Perseus’s total gold production for the

calendar year period, at an AISC of US$2,444 per ounce, generating notional cashflows of US$25 million over the 12 -

month period.

During Q2 FY26, the Complex produced 18,491 ounces of gold, representing a 58% increase compared with the prior

quarter. Production costs improved to US$1,545 per ounce and AISC to US$ 1,844 per ounce, compared with US$2,458

per ounce and US$2,826 per ounce, respectively, in the prior quarter. The improvement in the AISC is largely grade-driven

following the introduction of higher -grade ore from the Bagoé Gold Project, partially offset by higher royalties resulting

from higher realised gold prices during the quarter . In addition , an additional 2% was paid to the Government of Côte

d’Ivoire as described earlier.

Total material mined was lower during the quarter due to the completion of the Fimbiasso satellite project and the

gradual ramp-up at Bagoé, while a favourable strip ratio resulted in a significant increase in ore mined.

Mill runtime increased to 97%, compared with 91% in the prior quarter, which was impacted by scheduled maintenance.

Throughput averaged 184 tonnes per hour, up from 150 tonnes per hour in Q1 FY26, driven by a higher proportion of

oxide ore in the mill feed. Gold recovery decreased marginally to 89.5%, compared with 90.9% in the previous quarter.

With a weighted average realised gold price of US$3,227 per ounce, a 9% increase from US$2,953 per ounce in Q1 FY26,

the Complex achieved an cash margin of US$1,383 per ounce, compared with US$127 per ounce in the prior quarter. This

resulted in an notional cash flow of approximately US$25 million for the quarter up from $1 million achieved last quarter.

Notes:

1. Gold sales are recognised in Perseus’s accounts when gold is delivered to the customer from Perseus’s metal account

2. Included in the AISC for the quarter is US$1.9 million of costs relating to excess waste stripping. When reporting cost of sales, in line with accepted practice

under IFRS, this cost will be capitalised, and the costs amortised over the remainder of the relevant pit life

3. Royalties, Total All-In Site Cost, Cash Margin and Notional Cash Flow has been restated to include the additional 2% royalty costs royalty paid in FY26 Q2 but

relating to the respective periods.

4. FY26 Q2 AISC only includes additional 2% royalties paid in Côte d’Ivoire that relate to the December 2025 quarter. The December 2025 half year only includes

the Q1 and Q2 FY26 additional 2% royalty paid. A total of US$3.8 million was paid in FY26 Q2 of which US$1.3 million related to the December 25 quarter,

US$0.9 million related to the September 25 quarter and US$1.6 million related to the Q3 and Q4 of FY25.

MINERAL RESOURCE TO MILL RECONCILIATION

Table 9 shows the reconciliation of processed ore tonnes, grade and contained gold relative to the Sissingué MRE.

In Q2 FY26, ore tonnes processed were above block model predictions 18%, while the grade was 17% lower, resulting

in slight reduction in contained gold (-2%) compared to expectations. The lower grade performance is a result of mining

of narrow, variably mineralized structures at Sissingu é Main, Fimbiasso West and A irport West pits, with higher than

anticipated dilution in several benches. The 6 - and 12-month trends demonstrate improving correlation, with contained

gold now tracking within expectations of the block model. Operational controls, including blast design refinement and

improved ore mining control initiatives remain in place to minimise dilution and maintain alignment between the model

and mill outcomes going forward.
