OPERATIONS

PRODUCTION, COSTS AND NOTIONAL CASHFLOW

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

produce a total of 130,911 ounces of gold in the December 2022 quarter. The weighted average production cost at the

operations was US$881 per ounce, while the weighted average AISC incurred during the quarter was US$983 per

ounce of gold.

This performance, when combined with record gold production in the September 2022 quarter, gave rise to Half

Yearly gold production of 268,371 ounces of gold, produced at an average AISC of US$930 per ounce. This consistently

strong performance exceeded market production guidance for the December 2022 Half Year of 240,000 to 265,000

ounces of gold produced and bettered AISC guidance of US$1,000 to US$1,100 per ounce.

When combined with June 2022 Half Year production of 252,850 ounces at an AISC of US$955 per ounce, Perseus

delivered total production of 521,221 ounces of gold at an AISC of US$941 per ounce for the full 2022 Calendar Year.

In the December 2022 quarter, combined gold sales from all three operations totalled 203,154 ounces, including sales

of 93,634 ounces of bullion on hand at the end of the September quarter. The weighted average gold price realised

was US$1,748 per ounce, US$103 per ounce more than the September 2022 quarter price of US$1,645 per ounce.

Perseus’s average cash margin for the December 2022 quarter was US$765 per ounce, in line with the cash margin

achieved during the September 2022 quarter. Notional operating cashflow from operations was US$101 million,

US$11 million less than the September quarter, driven by slightly lower overall group gold production, combined with

higher AISCs at Sissingué and Yaouré.

These strong results, summarised below in Tables 1 and 2 below, confirm Perseus’s position as one of the world’s

better performing mid-tier gold producers in 2022.

Notes:

1. The September Quarter has been adjusted to reflect the actual achieved price of $1,847. No sales of Sissingué gold occurred during the

September quarter, the calculation of notional cash flow was based on the average sales price for the Group of US$1,645 per ounce less

Sissingué’s AISC, applied to the gold produced by the mine during the quarter.

YAOURÉ GOLD MINE, CÔTE D’IVOIRE

Refer to Table 3 below for details of operating and financial parameters recorded at the Yaouré gold mine during the

periods ending 31 December 2022 and relevant prior periods.

During the quarter, Perseus’s Yaouré gold mine produced 65,352 ounces of gold at a production cost of US$707 per

ounce and an AISC of US$798 per ounce. The weighted average sales price of the 126,174 ounces of gold sold during

the quarter was US$1,726 per ounce, giving rise to a cash margin of US$928 per ounce. Notional operating cashflow

generated during the quarter by Yaouré was US$60.7 million, or US$17.2 million less than in the September 2022

quarter.

This performance contributed to half yearly gold production at Yaouré of 136,821 ounces of gold at an average AISC of

US$724 per ounce, which was in the upper half of market guidance range for the half year of 130,000 to 140,000

ounces of gold produced and below AISC guidance of US$810 to US$875 per ounce.

The operating performance at Yaouré resulted from sound operating fundamentals relative to the prior quarter,

including mill run time (94.3% compared to 90.4%), and gold recovery rates (93.6% compared to 93.1%). The head

grade of processed ore (2.17 g/t compared to 2.43 g/t) and throughput rates (481 tph compared to 491 tph) both

lagged the outstanding metrics recorded in the prior period, reflecting a shift in the location of mining in the CMA pit.

MINERAL RESOURCE TO MILL RECONCILIATION

Table 4 shows the reconciliation of processed ore tonnes, grade, and contained gold relative to the Yaouré Mineral

Resource block model. During the last quarter, 16% more ore tonnes were processed at 14% lower grade for zero

variance in ounces compared to the Mineral Resource model. In the previous six months and project to date, In the

previous six months and project to date, Yaouré has produced more metal than the Mineral Resource model predicted.

The performance of the Yaouré Mineral Resource model to date is considered satisfactory, however work will continue

to optimise the grade and reduce dilution.

EDIKAN GOLD MINE, GHANA

Table 5 below summarises the key operating and financial parameters recorded at Edikan during the periods ending

31 December 2022 and relevant prior periods.

Edikan produced 53,850 ounces of gold at a production cost of US$935 per ounce and an AISC of US$1,058 per ounce

in the December quarter, slightly bettering the much improved performance in the September 2022 quarter relative

to prior periods. Gold sales of 52,601 ounces were 6% more than in the prior quarter, at a weighted average realised

gold price of US$1,754 per ounce, generating an average cash margin of US$696 per ounce, a significant improvement

on results achieved earlier in the year. In addition, notional cashflow of US$37.5 million was US$8.0 million better than

in the prior period.

This quarterly performance contributed to Half Yearly gold production at Edikan of 105,977 ounces of gold, produced

at an average AISC of US$1,059 per ounce. This production performance exceeded the top end of the market guidance

range for the Half Year of 90,000 to 100,000 ounces of gold produced and was well below the bottom end of the AISC

guidance range of US$1,190 to US$1,320 per ounce. This performance was a large improvement compared to the

June Half Year with production increasing by 38,719 ounces and AISC falling by US$500 per ounce.

Operating performance at Edikan was generated by sound operating fundamentals generally in line with the prior

quarter. Mill run time (95.9% compared to 91.3%) and gold recovery rates (91.4% compared to 89.7%) both improved

quarter-on-quarter, while head grade of processed ore (1.02 g/t compared to 1.04 g/t), and throughput rates (846 tph

compared to 861 tph) were down slightly on the prior quarter but remaining within acceptable tolerance ranges.

MINERAL RESOURCE TO MILL RECONCILIATION

Reconciliation of processed ore tonnes, grade and contained ounces relative to the Edikan Mineral Resource block

model is in Table 6 below.

During the last three months, grade control has predicted additional tonnes (+9%), exact grade and more ounces

(+8%) when compared to the Mineral Resource Estimate (MRE). Over the last six months, Edikan has also recorded

more contained metal than predicted by the MRE model but in the 12-month period, contained gold was slightly

under that predicted by the MRE. Therefore, Perseus regards the overall outperformance as being within normal

industry standards.

Notes:

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

2. The September Quarter has been adjusted to reflect the actual achieved price of $1,847. No sales of Sissingué gold occurred during the September

quarter, the calculation of notional cash flow was based on the average sales price for the Group of US$1,645 per ounce less Sissingué’s AISC,

applied to the gold produced by the mine during the quarter.

3. Included in the AISC for the quarter is US$0.95 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.

During the quarter, Sissingué produced 11,709 ounces of gold at a production cost of US$1,602 per ounce and an AISC

of US$1,672 per ounce.

During the quarter, the ore processed in the Sissingué mill was mined from the remnants of West Arm, Binkadi and

Bagoé pits at Sissingué while access is developed to the satellite pits at Fimbiasso East and West. Notwithstanding this,

overall production performance for the mine during the quarter was better than forecast with each of the key

operating parameters including runtime (92.1%), throughput rate (202 tph), and recovery (91.9%) in line with or better

than the prior quarter. Average head grade (0.97g/t) was down relative to the prior quarter in line with company

expectations, and it was this temporary reduction in grade that accounted for lower gold production during the

quarter.

The AISC of US$1,672 per ounce was in line with expectations falling in the lower half of the AISC guidance range. This

quarter, the AISC was increased by capital investment on infrastructure required to support the mining of the

Fimbiasso East and West pits that commenced following the end of the quarter.

The weighted average sales price of the 24,379 ounces of gold sold during the quarter was US$1,847 per ounce, giving

rise to an average cash margin of US$174 per ounce. As previously reported, no gold from Sissingué was sold in the

September quarter, and was included in the sale of the 24,379 ounces recorded this quarter. Most gold was sold into

specifically designated hedge contracts designed to preserve the cash margin during this period of high capital

expenditure. While the cash margin during the quarter reduced to US$174 per ounce of gold sold, for the full 2022

calendar year, the cash margin was US$406 per ounce, slightly higher than the minimum cash margin target of US$400

per ounce set by Perseus. Notional cashflow generated by the mine during the quarter totalled US$2 million.

This performance contributed to half yearly gold production at Sissingué of 25,573 ounces of gold, produced at an

average AISC of US$1,490 per ounce which exceeded the top end of the market production guidance for the Half Year

of 20,000 to 25,000 ounces of gold produced and fell below the bottom end of the AISC market guidance range of

US$1,600 to US$1,950 per ounce.

MINERAL RESOURCE TO MILL RECONCILIATION

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

block model is in Table 8 below. During the last three months, grade control has predicted additional tonnes (+19%) at

a reduced grade (-10%) resulting in an increase in overall ounces (+6%%) when compared to the Mineral Resource

Estimate (MRE). Over the last six- and 12-month periods, Sissingué has produced more metal than the Mineral

Resource model predicted. Perseus regards the overall outperformance as being within normal industry standards.

SUSTAINABILITY

SUSTAINABILITY GOVERNANCE

During the quarter, Perseus continued to strengthen its sustainability governance through the following:

• Completed Phase 1 of global health and safety cultural program ‘Safely Home Every Day’, which aims to align the

business around a common vision for health and safety and empowering personnel at all levels in Perseus ’s

organisation to understand their unique contribution in creating a safe workplace. Planning of the Health and Safety

improvement program was completed in May 2022. Implementation of Phase 1 of the Health and Safety

improvement program which involved all sites was finalized in November 2022. Phase 2 of the implementation will

occur in the June 2023 Half Year.

• Finalized the establishment of the Yaour é Community Development F und, with the C ôte d’Ivoire Government

signing a new decree specifying the method of operation of the Fund.

• Finalized the Environmental Impact Statement (EIS) for the Bagoé project near Sissingué, with the EIS report

validated, recommendations addressed, and the environmental permit for Bagoé granted.

• Conducted several employee and community training and awareness days in partnership with local non -

governmental organisations (NGOs) and community groups, with the intent of improving awareness of heart health,

breast cancer, malaria prevention, HIV/AIDs and female empowerment. Sites also conducted employee training on

safety culture, safe driving during the festive season, survi val swimming, emergency response scenarios and

harassment and violence in the workplace.

• Received approval to store and use explosives and a temporary water permit at Fimbiasso near Sissingué.

SUSTAINABILITY PERFORMANCE

This quarter, Perseus continued its strong sustainability performance relative to objectives and targets, as shown below

in Table 10 and summarised as follows:

• Safety:

– Lost Time Injury Frequency (LTIFR) across the Group reduced from 0.26 to 0.25. The sites achieved a safety

milestone, celebrating 1.6 million hours without a Lost Time Incident (LTI) for Edikan, 17.2 million hours without

an LTI for Sissingué, and more than 2.4 million hours without an LTI for Yaouré.

– Group Total Recordable Injury Frequency Rates (TRIFR) slightly increased from 1.19 at the end of the September

quarter to 1.44 at the end of December 2022, which is higher than the FY23 target of 0.8. This was driven by an

increase in Restricted Work Injuries at exploration sites. However, additional focus on safety performance at

Yaouré has led to significant improvement at that site over the quarter, from a TRIFR of 1.93 at the end of

September 2022 to 1.27 at the end of December 2022.

• Social:

- Total economic contribution to Perseus’s host countries of Ghana, Côte d’Ivoire and Sudan during the quarter

was ~US$116 million (approximately 33% of revenue), which included approximately US$99 million paid to

local suppliers representing 80% of procurement on Purchase Order Value basis, US$9 million paid as salaries

and wages to local employees, US$7 million in payments to government as taxes, royalties and other

payments, and around US$1.4 million in social investment (includes accrual for Yaouré). Sudan’s economic

contributions have been tracked for the first time this quarter and will continue to be included in future

reporting periods. Excluding Sudan, the proportion of procurement sourced from local suppliers was 87% for

the quarter ended December 2022, a significant increase from 78% for the quarter ended September 2022.

­ Local and national employment continued to remain above 95% for the reporting quarter. Across the Perseus

group, gender diversity declined slightly with the proportion of female employees ~14% for the quarter ended

September 2022 to 12% for the quarter ended December 2022, reflecting the industry in which we are involved

but more particularly, the cultural orientation of our host countries.

­ One Category 3 community event occurred in November 2022 where a member of the community barricaded

the road towards the mine at Sissingué. A meeting was organised the next day with the community member

and the Prefect of the local community and the issue was resolved . Another Category 3 community event

occurred on the Agyakusu AM exploration licence during the quarter when access to drill sites was denied by

landowners who were hosting illegal small-scale mining activities. Rather than exercise its legal rights, Perseus

withdrew from the area pending further discussions with landowners and local authorities.

• Environment:

- Total Scope 1 and 2 Greenhouse Gas emissions intensity per ounce of gold produced increased by 5.5% from

0.47 tCO2-e/oz for the quarter ended September 2022 to 0.496 tCO2-e/oz for the quarter ended December

2022. This continues to be well below peer average (0.78 tCO2-e/oz). Total emissions and emissions intensity

has reduced since start of the financial year due to Edikan’s increased use of gas for power.

­ Zero significant (Consequence 3) environmental or tailings dam integrity issues occurred during the period.

In achieving the above, the following sustainability challenges were encountered by Perseus during the quarter:

• A total of 11 employee and contractor injuries occurred during the quarter, which included one Medical Treatment

Injury (MTI) for a contractor.

• Illegal mining activities on Perseus’s mining and exploration licence areas continue to present challenges for the

Company in both Ghana and Côte d’Ivoire. The Company continues to work closely with relevant government

authorities to manage these activities that have proven to negatively impact both the environmental and social

fabric of local communities.

• There are ongoing tensions within the communities around Yaouré and Sissingué regarding local employment, local

business opportunities, pollution, and crop and land compensation.
