Successful Exploration at Perseus's Ivorian Gold Mines

Perth, Feb. 22, 2024 (GLOBE NEWSWIRE) -- 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 are included below and readers are referred to the full release with detailed results available on , and

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:

• YDD0594: 12m @ 4.58 g/t gold from 325m and 3m @ 6.27 g/t gold from 349m

YAOURÉ - ZAIN 1 – The program is ongoing and is designed to assess near-surface mineralisation identified during the CMA underground north extension drilling. Assay results have returned significant gold intercepts including:

• YRC2411: 7m @ 3.56 g/t gold from 3m

SISSINGUE - FIMBIASSO WEST – A review of the mineralisation at Fimbiasso has identified potential to increase the Mineral Resource. A three-phase drilling program was designed to infill and extend the mineralisation and is currently underway. Results to date are encouraging with the primary mineralised zone intersected down dip and along strike. Significant results include:

• FMRC0040: 6m @ 3.78 g/t gold from 118m

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 campaigns 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.”
