SUCCESSFUL EXPLORATION AT PERSEUS’S IVORIAN GOLD MINES

Perth, Western Australia/February 22, 2024/Perseus Mining Limited (ASX/TSX: PRU) is pleased to provide an update

on ongoing exploration activities conducted at and around its two operating gold mines in Côte d’Ivoire.

At the Yaouré Gold Mine , exploration drilling continues to demonstrate the down dip potential of the CMA

underground Mineral Resource; and adds further confidence in opportunities to expand the Yaouré open pit Mineral

Resource. While targeting the continuation of the CMA structure at depth, drilling has located previously unidentified

shallow mineralisation located immediately east of the CMA pit. This mineralisation has been termed the Zain 1

Prospect.

At the Sissingué Gold Mine and Fimbiasso Satellite Pits, ongoing exploration continues to identify extensions to existing

mineral deposits and other prospects that have significant potential to extend the life of the Sissingué operation.

HIGHLIGHTS

YAOURÉ - CMA UNDERGROUND NORTH EXTENSION - The objective of this program is to infill the existing drilling to a

nominal drill pattern of 25 m × 25 m to target an upgrade of the Mineral Resource to higher confidence categories. A

secondary objective is to complete step out drilling to the north to test for extensions to the CMA mineralisation. While

the program is ongoing, results to date include:

NEWS RELEASE | SUCCESSFUL EXPLORATION AT PERSEUS’S IVORIAN GOLD MINES

PERSEUSMINING.COM

Perseus’s Chairman and CEO, Jeff Quartermaine, said:

“Perseus considers that organic growth through successful exploration , is the most cost-effective way to grow our

business and to create value for stakeholders. To deliver this outcome, Perseus has been funding active exploration

programs at all three of its operating sites including the Yaouré and Sissingué gold mines in Côte d’Ivoire and the

Edikan gold mine in Ghana.

The encouraging drilling results reported today from our latest exploration campaign s conducted in and around the

Yaouré and Sissingué gold mines, provide clear evidence that we are well on track to not only improve the quality of

our existing asset base by extending the lives of each of these mines, but also maintaining Perseus’s targeted levels

of combined gold production of more than 500,000 ounces of gold per year to the end of the current decade and

beyond.”

CENTRAL CÔTE D’IVOIRE

YAOURE GOLD MINE – EXPLORATION UPDATE

Perseus is currently mining the CMA orebody at the Yaouré Gold Mine in Côte d’Ivoire using conventional open -pit

mining methods. The CMA is a tabular zone of mineralisation 2-20 metres thick, which generally grades at 3 -7 g/t

gold and dips to the east at 20 -35 degrees but can be shallower or steeper locally. Over the past few years’

exploration has continued to expand the Mineral Resources and Ore Reserves and has demonstrated the economic

viability of an underground operation on the CMA Lode below the CMA open pit.

In August 2023 the company announced an increase to CMA underground Ore Reserves beneath the existing CMA

open pit, of 2.7 Mt at 3.46 g/t gold for 300,000 ounces. The total CMA underground Ore Reserve is now estimated

to be 4.9 Mt at 3.51 g/t gold for 559,000 ounces. The CMA orebody remains open down plunge and down dip below

the current Indicated Mineral Resource, and further extensions to the CMA underground Ore Reserves are expected

with future drilling during FY24. Feasibility-level studies on the CMA deposit at Yaouré (approximately four hundred

metres down dip from the base of the open pit) have confirmed the economic and technical viability of underground

mining.

In August 2023 as well as announcing the growth to Ore Reserves for the CMA underground, results of the FY23

exploration drilling campaign at the Yaouré open pit were released. The Y aouré open pit drilling programs have

resulted in 6.9 Mt at 1.82 g/t gold for 403,000 ounces of additional Yaouré open pit Ore Reserves (separate to the

CMA open pit). Yaouré open pit Ore Reserves now total 11.8 Mt at 1.49 g/t gold for 565,000 ounces. The increase to

Yaouré open pit Ore Reserves is based upon conversion of Inferred Mineral Resources immediately beneath the

existing Yaouré open pit to Indicated Mineral Resources.

CMA UNDERGROUND NORTH PLUNGE

The Phase One drill program has been completed and all assay results have been received. The program consisted

of a total of 27 holes for an aggregate of 11,349 meters. Phase One comprised approximately 2,160m of RC and

9,189m of diamond drilling. The aim being to infill the existing drilling to a nominal drill pattern of 25 m × 25 m and to

upgrade resources to higher confidence resource categories. The Phase Two program is underway with 4,581 m

completed to date to achieve a nominal 100 m × 100 m drill spacing to assess the plunging minerali sation towards

the north. Infill drilling has returned high-grade intercepts including:

o YDD0608: 14.25m @ 3.95 g/t gold from 566.75m

o YDD0616: 4m @ 2.58 g/t gold from 138m, and 14m @ 5.41 g/t gold from 420m

YAOURE WEST PROGRAM

A review of exploration potential on the Yaouré West permit has prioritised several high-quality exploration targets

which are currently being assessed. In addition to this , a drone magnetic survey has been completed targeting the

eastern contact of an intrusion, NW trending fault blocks, and a target defined from the interpretation of airborne full

tensor gravity gradiometry data. Auger and aircore drilling programs are expected to commence Q1 24.

YAOURÉ EXPLORATION NEXT STEPS

Perseus’s ongoing exploration and study programs at Yaouré will focus on continuation of drilling to upgrade the status

of Mineral Resources at CMA and Yaouré open pit and to continue drilling down dip of the current CMA underground

Mineral Resource to identify the potential for further resource extensions. In addition to this the Zain 1 Prospect will

continue to be investigated. Drill testing of targets at Yaouré West as well as those generated from the 3D seismic

survey will also be undertaken during H1 2024.

Figures illustrating the key aspects of the Central Côte d’Ivoire exploration activities are presented in Appendix 1. Drill

collar details and significant intercepts (>2 m above 0.5 g/t gold Au) are summarised in Table 1 in Appendix 2.

NORTHERN CÔTE D’IVOIRE

SISSINGUÉ GOLD OPERATION – EXPLORATION UPDATE

The Sissingué Operation is located in the north of Côte d’Ivoire, near the border of Mali, and commenced production

in January 2018. Ore is sourced from one main open pit and several smaller satellite open pits on the Sissingué Mining

Licence as well as from the Fimbiasso East and West Satellite Pits, located some 50 km west, and processed through a

conventional 1.4 million tonnes per annum CIL processing facility.

A review of exploration opportunities on the Sissingué and Fimbiasso mining licences as well as the Mahale exploration

permit, identified a number of potential targets which have been drill tested over the past seven months. At Sissingué

initial results from the Airport West prospect look encouraging although further work will be needed to determine the

extent of mineralisation and potential economic viability. At the currently operating Fimbiasso West deposit ongoing

drilling continues to demonstrate along strike and down dip extension potential.

AIRPORT WEST

RC drilling was conducted at Airport West and Binkadi to follow up on previous drill results. Some 3,890m were drilled

in 46 RC holes. More significant intercepts received to date include:
