December 2021, after returning US$13 million (A$18 million) of capital to shareholders, reducing debt by US$50

million (A$68 million) and investing US$11 million (A$15 million) in organic growth during the quarter.

OPERATIONS

QUARTERLY PRODUCTION, COSTS AND NOTIONAL CASHFLOW

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

produce a total of 128,378 ounces of gold in the December 2021 quarter, 14% more than in the prior quarter. The

weighted average production cost at the operations was US$823 per ounce, while the weighted average AISC incurred

during the quarter was US$934 per ounce of gold. Production costs and AISC’s were 4% and 3% respectively, lower

than comparative costs in the previous quarter.

This performance contributed to Half Yearly gold production at our three mines of 241,164 ounces of gold, produced

at an average AISC of US$949 per ounce. This strong performance compared favourably to market guidance for the

Half Year of 225,000 to 255,000 ounces of gold produced at an AISC of US$925 to 1,025 per ounce and has positioned

Perseus to achieve our corporate objective of producing more than 500,000 ounces of gold at a margin of greater than

US$400 per ounce in FY2022.

YAOURÉ GOLD MINE, CÔTE D’IVOIRE

During the quarter, Perseus’s newest mine, Yaouré, increased its gold production by a further 16% compared to the

prior quarter to 75,189 ounces of gold at a production cost of US$589 per ounce and an AISC of US$700 per ounce.

The weighted average sales price of the 79,669 ounces of gold sold during the quarter was US$1,699 per ounce, giving

rise to a cash margin of US$999 per ounce. Notional operating cashflow generated by Yaouré was US$75.1 million

during the quarter, US$9.3 million more than in the September 2021 quarter. Refer to Table 3 below for details of

operating and financial parameters.

This performance contributed to half yearly gold production at Yaouré of 139,747 ounces of gold, produced at an

average AISC of US$687 per ounce which compared favourably to market guidance for the half year of 130,000 to

140,000 ounces of gold produced at an AISC of US$675 to US$775 per ounce.

NEWS RELEASE | DECEMBER 2021 QUARTER REPORT

PERSEUSMINING.COM

The improving operating performance at Yaouré was a result of strong operating fundamentals compared to the prior

quarter, including mill throughput rates (487 tph compared to 449 tph), gold recovery rates (93.6% compared to

92.7%) and importantly, the head grade of processed ore (2.64 g/t to 2.37 g/t).

MINERAL RESOURCE TO MILL RECONCILIATION

The reconciliation of processed ore tonnes, grade and contained gold relative to the Yaour é Mineral Resource block

model are shown in Table 4. During the last quarter, 17% more ore tonnes at 10% lower grade for 6% more ounces have

been produced compared to the Mineral Resource model. Over the last six months and project to-date, Yaouré has

produced more metal than predicted by the Mineral Resource model. The performance of the Yaouré Mineral Resource

model to date is considered satisfactory, however work will continue to optimise the grade and reduce dilution.

SISSINGUÉ GOLD MINE, CÔTE D’IVOIRE

During the quarter, 18,065 ounces of gold were produced at Sissingué at a production cost of US$817 per ounce and

an AISC of US$905 per ounce. The weighted average sales price of the 16,621 ounces of gold sold during the quarter

was US$1,638 per ounce, giving rise to a cash margin of US$732 per ounce. Notional cashflow generated from the

Sissingué operation totalled US$13.2 million for the quarter, US$ 2.1 million more than in the prior quarter, due to a

combination of improved production, costs and average gold sale prices. Refer to Table 5 below for details of

operating and financial parameters.

This performance contributed to half yearly gold production at Sissingué of 34,132 ounces of gold, produced at an

average AISC of US$917 per ounce. This outstanding performance materially exceeded market guidance for the half

year of 25,000 to 30,000 ounces of gold produced at an AISC of US$950 to US$1,070 per ounce.

The overall result for the quarter at Sissingué, was also better than forecast by Perseus with each of the key operating

parameters including runtime (95%), throughput rate (178 tph), and recovery (90%) improving relative to the prior

quarter. Average head grade (1.67g/t) was down relative to the prior quarter in line with company expectations.

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 6 below. During the last three months, grade control has predicted similar tonnes (100%) grade

(99%) and ounces (99%) when compared to the Mineral Resource Estimate (MRE). Over the last six- and 12-month

periods of operation, Sissingué has produced more metal than predicted by the Mineral Resource model. Perseus

regards the overall outperformance as being within normal industry standards.

UPDATED LIFE OF MINE PLAN FOR THE SISSINGUÉ OPERATION

An updated Life of Mine Plan for the Sissingué operation that models the mining and processing of ore from each of

the Sissingué, Fimbiasso and the yet to be granted, Bagoé exploitation permit areas, is being prepared and will be

published in the June 2022 quarter when the results of a recent successful drilling campaign in and around the existing

Sissingué pits are fully collated, understood and incorporated into the revised mine plan and processing schedule.

Based on preliminary optimisations and scheduling, it indicates that the life of the Sissingué operation could be

extended by several years. Current work is focusing on the sequencing of mining to optimise the return on the

investment of capital required to access the new mining areas.

BAGOÉ MINING LEASE

Work by consultants (CECAF), on preparing an Environmental and Social Impact Assessment (ESIA) for the Bagoé

exploration permit area was completed during the quarter. The ESIA has been lodged with the environmental

regulator (ANDE) for approval. Once approval is granted, it will be lodged with the Department of Mines, Petroleum

and Energy together with the recently completed Definitive Feasibility Study of an operation located on the Bagoé

exploration permit. This is expected to occur during the June 2022 quarter and an Exploitation Permit should be

granted once assessment of the submissions is complete.

EDIKAN GOLD MINE, GHANA

In the December 2021 quarter, Perseus produced 35,124 ounces of gold at Edikan (9% more than in the September

quarter) at a production cost of US$1,327 per ounce and an AISC of US$1,450 per ounce. Gold sales of 34,196 ounces

were 17% more than in the prior quarter, at a weighted average realised gold price of US$1,613 per ounce. This

generated a cash margin of US$163 per ounce, a significant improvement on the prior quarter. Notional cashflow of

US$5.7 million, was US$4.8 million better than in the prior period. Table 7 below summarises the key operating and

financial parameters.

While the overall performance of Edikan was materially better than in the September quarter, there is still significant

room for improvement. Signs of this improvement were evident in the month of December when the mill feed was

made up predominantly of ore from the AG Pit which resulted in the head grade of ore treated increasing sharply to

0.86g/t on average and the gold recovery rate increasing to 86.2%.

This quarterly performance contributed to Half Yearly gold production at Edikan of 67,285 ounces of gold, produced at

an average AISC of US$1,509 per ounce. This performance fell short of market guidance for the Half Year of 70,000 to

80,000 ounces of gold produced at an AISC of US$1,350 to 1,450 per ounce.

The shortfall in production relative to guidance was a function of several factors including poor reconciliation of

tonnes and grade of ore mined from the AG pit in the September 2021 quarter and a conscious decision by Perseus to

process ore from low grade ore stockpiles during the December quarter until a comprehensive grade control

programme could be completed to provide a thorough understanding of the distribution of gold bearing material in

the upper benches of the pit. As noted above, in December a marked improvement in head grade and recovery of ore

had been achieved giving confidence in forecasts for future periods.

MINERAL RESOURCE TO MILL RECONCILIATION

The disconnect in the Edikan reconciliation has been analysed in detail to understand the performance to ensure that

the trend will not continue in the Stage 3 cutback of the AG Pit. From the work undertaken, it is apparent that the

large block size in the resource model (20 metres x 20 metres x 10 metres) is the cause of the issue whilst mining

around an existing cutback void. Material that is present in the large block has already been partially mined in the

previous Stage 2 pit, which was the higher-grade part of the large block. Overall, the pit continues to reconcile well,

however this section of the cutback is strongly affected by this circumstance. The pit mining is within 10 metres of

reaching the previous cutback base, and from here it is expected the reconciliation will revert to previous correlation

of ~95%-105% overall.

Additional drilling has been undertaken this quarter to confirm the continuity of the grade and geology. The drilling

assays returned emulated the block model grades giving good confidence in the ongoing cutback ore content and has

enhanced the geological model. The Edikan Block Model to mill reconciliation figures are shown in Table 8 below.

SUSTAINABILITY

COVID-19 UPDATE

A fourth wave of COVID-19 has spread across West Africa during the quarter, with higher infection rates consistent

with the Omicron variant. In response, Perseus continued to update its COVID-19 critical controls, with focus on

keeping its people safe and healthy, maintaining safe and stable operations, and supporting host governments and

local communities. Although around 190 cases of COVID-19 have been recorded across the Company’s operations

since the beginning of the pandemic, no cases have led to serious illness and our controls have been effective in

limiting the spread in our workforce.

During the quarter 60 new cases of COVID-19 were recorded, mainly at the Edikan and Yaouré operations and almost

all in the month of December. Vaccination campaigns progressed across our operations, and with increased vaccine

availability across the region, around 50 per cent of Perseus’s employees and contractors are now fully vaccinated.

Efforts continue to improve vaccination rates as they become available under government programs.

SUSTAINABILITY GOVERNANCE

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

• Releasing the second Modern Slavery Statement in line with the Australian Modern Slavery Act 2018 (Cth), for the

period 1 July 2020 to 30 June 2021, providing further information on the human rights risk profile of Perseus’s

global supply chain, and outlining its human rights and modern slavery due diligence program.

• Commencing a global project to transform Perseus’s health and safety approach and performance across the

operations in line with international best practice, focusing on leadership, culture, capability and risk

management. The work will be delivered throughout the remainder of FY22 and FY23.

• Commencing an independent review of closure plans and cost estimates, to be completed by the end of Q3.

• Updating security risk assessments at Sissingué due to the increased terrorism risks in countries to the north of

Côte d’Ivoire associated with activity of Jihadist groups in the Sahel region.

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:

NEWS RELEASE | DECEMBER 2021 QUARTER REPORT

PERSEUSMINING.COM

• Safety: Perseus’s record of zero fatalities across the operations was maintained, and safety performance

improved significantly from the previous quarter at Edikan and Sissingué, with Total Recordable Injury Frequency

Rates (TRIFR) to the end of December 1.36 and 0.0 respectively. The TRIFR across the Group was 1.49, a significant

improvement on the September quarter and our FY21 performance, however still higher than our FY22 target of

1.3. Sissingué achieved 1 year without a recordable incident, and Edikan was awarded the Best Performer in

Occupational Health and Safety during the 7th Ghana Mining Industry Awards, established by the Ghana Chamber

of Mines.

• Social:

– Total economic contribution to Perseus’s host countries of Ghana and Côte d’Ivoire for the financial year to

date of around US$223 million (around 60% of revenue), included approximately US$166 million paid to local

suppliers, US$21 million paid as salaries and wages to local employees, US$35 million in payments to

government as taxes, royalties and other payments, and around US$591,000 in social investment.

– Local and national employment has been maintained at above 95% for the quarter, and local

procurement around 81%.

– Zero significant community events occurred.

• Environment:

– Scope 1 and 2 greenhouse gas emissions remained steady from the first quarter. Water intensity increased

slightly due to dry season conditions across the region.

– As part of development of Perseus’s emissions reduction strategy, two vendors were shortlisted to support

further detailed studies to partially replace the diesel fired back-up generators at Yaouré with solar power.

– Zero environmental events or significant tailings dam integrity issues occurred during the period.

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

• Total Recordable Injury Frequency Rates (TRIFR) at Yaouré increased from 3.24 in the September quarter to 3.49,

tracking significantly higher than its FY21 result of 1.59 and higher than its FY22 target of 2.2. Given its

performance and the significant work required to embed Perseus’s Health and Safety standards at this new

operation, Yaouré will be the primary focus of the Health and Safety improvement program for the remainder of

FY22.

• Government administrative delays to the establishment of the Yaouré Community Development Fund, and

associated delays to commencement of community projects. Perseus is working with Government to establish the

fund as soon as possible, and community funding is being accumulated in an account each month since

commercial production was achieved at Yaouré.

• Illegal mining activities on Perseus’s mining and exploration licence areas continues 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.

• Ongoing tensions with the community around Yaouré regarding employment and business opportunities and land

compensation.

• Security risks at Sissingué and satellite exploration activity areas (Fimbiasso and Bagoé) are being closely

monitored due to ongoing political and social unrest which has given rise to terrorist activities in Mali which lies

immediately to the north of the Sissingué mine.
