Perseus Mining Limited provided an update on the suite of growth projects being
pursued at its Yaouré Gold Project in Côte d’Ivoire, including results from on-going resource definition drilling, deposit reconciliation performance, and planned work programs.

Highlights

• CMA underground performing well and transitioning to operation.
• An additional jumbo to be mobilised to increase future ore delivery and develop future underground exploration drill drives
• Yaouré open pit has identified +24% more metal from the trailing 6 months to March’26 against Reserve model with additional mineralisation domains being defined
• Drilling at depth and along strike of existing mining areas has strengthened confidence in the potential to extend mine life
• Extension drilling at CMA underground delivers encouraging results indicating potential extension of mineralisation beyond current defined Mineral Resource.
• Exploration drilling beyond the boundary fence has produced positive results at both the CMA Southwest and ROZA deposits.
• $34M committed to drilling in FY27 to increase the Mineral Resource base.
• The FY27 work plan targets the conversion of Inferred Resources to extend the Yaouré open pit

Perseus’s Managing Director and CEO, Craig Jones, said:
“Yaouré continues to demonstrate why it is a cornerstone asset in our portfolio. The successful transition of CMA Underground into stoping operations reflects the strength of our in-house team and their ability to execute complex underground developments safely and to schedule.
Equally pleasing is the performance of the Yaouré open pit, which has now delivered more than 20% additional gold relative to our Reserve model year to date, while our drilling continues to define new mineralisation domains both at depth and along strike. Extension drilling at CMA Underground has produced encouraging results pointing to mineralisation beyond the currently defined Mineral Resource, and our exploration success beyond the boundary fence reinforces our confidence that Yaouré’s mine life can be extended well beyond current estimates.
Our optimistic outlook provides confidence to invest in $34M exploration and in-fill drilling studies at Yaouré in FY27 and underscores our disciplined approach to organic growth — investing in the drill bit to convert Inferred Resources and extend the life of an asset we know intimately. This is precisely the model that has consistently created value for our shareholders, and we look forward to updating the market as these programs progress.”
