ADELAYDE EXPLORATION FORMULATING PLANS FOR THE NEXT PHASE OF WORK ON THE PERRON-EAST GOLD PROJECT IN QUEBEC

Adelayde Exploration Inc. is formulating work plans for the 9,168-acre Perron-East gold project in Quebec, located in the direct vicinity of Amex Exploration Inc. On April 13, 2026, Amex Exploration Inc. announced a positive feasibility study for the development of the Perron gold mine. Highlights from Amex's feasibility study include:gold production to average 147,000 ounces per year over the five years of commercial phase 1 production at an all-in sustaining cost (AISC) of $910 (U.S.) per ounce gold; projected after-tax internal rate of return of 114.6 per cent and after-tax net present value (discounted at 5 per cent) of $1.13-billion generated from a cumulative undiscounted after-tax cash flow of $1.44-billion at an assumed gold price of $3,500 (U.S.) per ounce. Management cautions that past results or discoveries on properties in proximity to Adelayde may not necessarily be indicative of the presence of mineralization on the company's properties.

James Nelson, president of Adelayde, stated: "With gold prices remaining strong, we look forward to starting our next phase of work on the Perron-East gold project in Quebec. In short time, Adelayde is expecting to be active on multiple projects, including our George Lake South antimony project, our Sisson North tungsten project in New Brunswick and on our Perron-East gold project in Quebec. Adelayde is well funded and will be very active throughout the remainder of the year."
