EXPLORATION UPDATE FOR MEYAS SAND GOLD PROJECT - SUDAN

Perth, Western Australia/ May 27, 2024/Perseus Mining Limited (ASX/TSX: PRU) is pleased to provide an update on

exploration activities and studies completed to date at its Meyas Sands Gold Project (MSGP) in Sudan.

Since acquiring the MSGP in May 2022, Perseus has focussed on the development of the Galat Sufur South (GSS) deposit,

and when possible, has conducted infill resource definition drilling, sterilisation trenching and drilling, a passive seismic

survey, hydrogeological, metallurgical, and geotechnical work in preparation for the inclusion of data in a Front-End

Engineering and Design (FEED) Study and a Final Investment Decision (FID) for the project.

With the outbreak of hostilities in Sudan in April 2023 , exploration activities on the MSGP site were temporarily

suspended but recently, Perseus’s personnel have re-established facilities to support on-site exploration activities and

in-house security teams at the MSGP camp.

With this restoration work well advanced, Perseus is pleased to announce that drilling at the MSGP recommenced on

20 May 2024. This initial drill program is aimed at testing high priority exploration targets in the vicinity of the GSS

deposit to follow up the drilling results that have been received to date. These results have confirmed the grade and

tenor of the GSS deposit, and while incomplete, are considered very encouraging. More significant results include:

Perseus’s Chairman and CEO Jeff Quartermaine said:

“When Perseus acquired the Meyas Sand Gold Project in 2022 through the acquisition of Orca Gold Inc, we were very

excited by the prospects of developing a large scale, low cost, long life gold mine in northern Sudan that would add a

further high quality mine to Perseus’s multi mine, multi-jurisdiction asset portfolio.

The outbreak of hostilities in the south and west of Sudan in 2023 represented a serious setback for Perseus’s ambitions

for MSGP, but the recent recommencement of drilling activities is considered a positive step forward that hopefully will

lead to the development of MSGP when peace is finally restored throughout the country.

The confirmatory drilling results that have been achieved by our team to date at MSGP are very encouraging and we

are now looking forward to returning further strong results that will lead to the conversion of the published Foreig n

Reserve Estimate for MSGP into an updated Ore Reserve reported in accordance with JORC 2012 on which a FEED study

can be confidently based.”

Plate 1: Reverse circulation drilling Kwandagawi Prospect located some 4km north west of GSS Main deposit.

BACKGROUND

The MSGP is situated in the far north of Sudan, approximately 75km south of the border with Egypt, and is fully

permitted by the Sudanese Government with a Mining Lease, Royalty agreement and a water permit formally granted

incorporating attractive fiscal terms, and clearly delineated rights and obligations of key stakeholders.

Since the acquisition of MSGP, Perseus made strong progress towards preparing for a possible FID on the MSGP in the

second half of 2023. However, in late April 2023, following the outbreak of armed conflict in Sudan, largely in and

around Khartoum, between the Sudanese Armed Forces and an influenti al militia group, the Rapid Support Force,

Perseus withdrew most of its employees from the MSGP site pending a resolution of the conflict with the safety of its

staff being the number one priority for the Company.

Although hostilities between the combatants continue in certain parts of Sudan, the area in which MSGP is located has

not been the scene of conflict, and there have been no reported incidents involving the combatants in an area of

approximately 250,000 square kilometres around the site.

Notwithstanding the above, Perseus considers that proceeding with the execution of a complex mine development

project in the context of ongoing insecurity and the reported destruction of the country’s industrial base in Khartoum,

would be unwise. As a result, the pending FID on the development of Meyas Sand has been deferred until confidence

in the future of Sudan as a viable investment destination is restored. At this stage, there is no clear line of sight to when

this might occur.

The MSGP site has subsequently been secured by a security force led by Perseus’s in -house security personnel, and

include representatives of the Sudanese Mining Police, a body that operates under the control of the Ministry for

Minerals, as well as representatives of our host communities.

The refurbishment and construction of the camp continues to make good progress, supply lines and logistics have largely

been reestablished and exploration activities within the mining lease area resumed on 20 May 2024. Drilling will focus

on continuing the drill out the GSS deposit.

To date, Perseus has conducted a range of activities associated with MSGP which have included but not been limited to:

• Low level exploration activities including mapping and sampling as well as interpretation of available data with

a view to better understanding the GSS deposit.

• Engineering and preparation of FEED studies performed by Perseus and its engineering contractor,

Lycopodium, to optimise previous engineering planning and design work.

• Infill and sterilisation drilling program designed to infill prior drilling of the GSS deposit to confirm the estimated

Mineral Resource and Ore Reserve, as well as confirm proposed infrastructure locations through sterilisation

of the sites.

• Australasian Groundwater and Environmental Consultants continued hydrology modelling, after completing a

programme of pressure testing, (specifically recharge rates) of the aquifer located in Area 5 that will become

the primary water source for what will become the Meyas Sand Gold Mine. Progress to date gives Perseus

confidence that the aquifer will support water requirements for the projected life of the mine.

• A passive seismic survey was conducted to identify localised sources of construction water.

• Construction of site access roads progressed, with completion of 10km of the 100km pipeline corridor road.

• Knight Piesold completed an initial design review on the proposed Tailings Storage Facility (TSF). Detailed

engineering was suspended in April 2023.

• Design review on the 100km raw water pipeline by Fortin Pipelines was completed. Detailed engineering was

suspended in April 2023.

• A tender process for supply of a Hybrid -Renewable power station commenced but was suspended in April

2023.

• Significant progress was made to prepare the site facilities to support the initial construction phase.

• Construction tooling and assets were procured to support an initial construction site capability.

• Additional metallurgical test work and a review of existing data was conducted.

GSS INFILL DRILLING

To date, Perseus has focused exploration activities on the MSGP at the GSS prospect and specifically at GSS Main and

GSS East deposits. Results received to date, while incomplete, are viewed as encouraging and give a degree of

confidence in the current foreign estimate. Detailed geological and resource modelling work has been undertaken and

we have advanced our understanding of geology and mineralisation including geometry, grade distribution and

variability, metallurgy, geotechnical aspects.

Infill drilling commenced in January 2023 but was suspended due to security and safety considerations in April 2023. At

that time a total of 11,912 metres of combined RC and diamond drilling, including 4,575 metres at GSS Main and 7,337

metres at GSS East, in 34 completed holes and 46 pre-collars had been completed.

While assay results are incomplete, those results to hand are considered encouraging. More significant results include:

• GSRD00883B (pre-collared diamond tail) - 4.1m @ 5.48 g/t Au from 181.9m (including 2.1m @ 9.42 g/t Au from

Locations of holes in Figures in Appendix 1 and a full list of intercepts are included in tables in Appendix 2.

GSS STERILISATION DRILLING

Mapping, sampling and sterilisation drilling commenced in December 2022 but as noted, was suspended due to security

and safety considerations in April 2023. The drilling completed to date comprises 8,536 metres of RC drilling in 85 RC

holes. The results received so far confirmed the lack of mineralisation on the areas tested by sterilisation drilling. See

Figure 6 in Appendix 1.

It is important to note that following the outbreak of hostilities in April 2023 , the MSGP site was visited by vandals

following the temporary withdrawal of Perseus’s staff. These vandals damaged, destroyed or contaminated a number

of samples from drilled holes and these samples cannot be recovered.

NEXT STEPS AT GSS

It is intended that as soon as practical, Perseus will convert the published Foreign Reserve Estimate for the Meyas Sand

Project, into an Ore Reserve prepared in accordance with the requirements of JORC 2012. Exploration drilling will be

also conducted on the broader Block B exploration license.

This announcement has been approved for release by Perseus’s Chairman and Chief Executive Officer, Jeff

Quartermaine.
