Paterson Exploration Review Update

• First pass review of exploration data received from IGO complete
• Numerous targets identified, including north of Nifty and in Broadhurst Formation
• Significant potential to extend known copper mineralization at Rainbow Prospect

Cyprium Metals has completed a first pass review of exploration data received from IGO, following the dissolution of their joint venture and farm-in agreement. IGO's exploration activities over the past five years, which included $24 million in expenditure, have identified numerous targets that Cyprium plans to further evaluate. These include targets north of the Nifty deposit in Lamil Group rocks, as well as targets in the Broadhurst Formation which hosts the Nifty and Maroochydore deposits. Of particular interest is the potential to extend known copper mineralization at the Rainbow Prospect, where historic drilling has returned significant intercepts. Cyprium will focus on detailed evaluation of the Rainbow Prospect, as well as other targets such as Stirling, NL04b and MB01, with field work planned to commence in the first half of 2026.

Cyprium plans to undertake further evaluation of the Rainbow Prospect, including geophysical surveys and drilling programs, as well as detailed evaluation of other exploration targets within its Paterson Exploration Project.
