Perseus Pours First Gold at Yaouré Five Weeks Ahead of Schedule

PERTH, Western Australia, Dec. 17, 2020 --

Perseus Mining Limited (“Perseus” or the “Company”) (TSX & ASX: PRU) is pleased to advise it has successfully completed

the first pour of gold at its Yaouré Gold Mine in Côte d’Ivoire. Perseus achieved this important milestone nearly five weeks

ahead of schedule, consistent with its “stretch target” of first gold at Yaouré in December 2020.

With construction of the Yaouré processing plant and associated infrastructure largely complete, Perseus will now focus on

satisfying continuous performance tests and positioning to declare Commercial Production. Perseus expects to achieve both

during the March 2021 quarter, when the first shipment of gold from the Yaouré mine site is also expected to occur.

Perseus acquired Yaouré when it merged with Amara Mining plc in April 2016. Since then, the Company has completed an

extensive programme of confirmatory drilling and test work and prepared a definitive feasibility study (DFS). After permitting

and negotiating a Mining Convention with the Ivorian government, construction of the US$265 million mine started in August

2019.

Initially, lower grade oxide ore mainly from decommissioned heap leach pads will be processed in the Yaouré plant pending

access to higher grade fresh ore from the CMA pit. During the first five years of the Yaouré mine life, our DFS forecasts annual

gold production averaging around 215,000 ounces at a weighted average all in site cost of (AISC) of approximately US$750 per

ounce. An updated Life of Mine Plan for Yaouré, taking the actual commissioning date, current mining rates, operating costs

and possible increases in Mineral Resources into account, is scheduled for release in the March 2021 quarter.

With the successful development and commissioning of Yaouré, Perseus will own and operate three gold mines (Edikan,

Sissingué and Yaouré) in two West African countries (Ghana and Côte d’Ivoire) and will be on track to achieve its goal to

produce more than 500,000 ounces of gold per year at a cash margin of more than US$400 per ounce, and become a reliable

intermediate gold company that generates material benefits for all of its stakeholders.

Perseus’s Managing Director & Chief Executive Officer, Mr Jeff Quartermaine said:

“Pouring our first gold at Yaouré yesterday represented the achievement of a major milestone in the construction and

commissioning of Perseus’s third gold mine. It also represented the delivery of another promise made to shareholders by

Perseus’s management team, namely, to achieve its stretch target of first gold at Yaouré in December 2020. 

Being able to successfully develop the Yaouré Gold Mine, ahead of schedule and under budget during a year in which the

COVID-19 pandemic has severely disrupted many businesses around the world, is a testament to the skill, resilience and

dedication of our in-house development team, technical and commercial support staff, our contractors and consultants.  

We are now looking forward to achieving our next target of increasing our production to more than 500,000 ounces of gold per

year at a cash margin of not less than US$400 per ounce in FY2022. We will also extend our capacity to consistently produce

gold at these levels for many years to come by organically increasing our Ore Reserve inventory through successful near-

mine exploration programmes across our three mines.”
