DRILLING COMMENCES AT BLUE LAKE

Cupani Metals Corp.'s winter 2026 drill program has begun.

Cupani's 2026 winter drill program ranges from 15 to 25 holes for a total of between 3,000 and 4,000 metres. The program is designed to test the interpreted extension of the Blue lake mineralization to the southeast along the High-Potential corridor.

Drill locations were chosen based on confluence of surface geology that includes the presence of mineralized ultramafics and geophysics including aeromagnetic anomalies, electromagnetic responses and gravity anomalies. The proposed depth for each drill hole is planned as sufficient to reach the ultramafic/sediment contact. Cupani may choose to keep the drill rig on site beyond April for use later in 2026.

Cupani's 100-per-cent-owned Blue Lake copper-nickel-platinum-group-element project in Quebec covers 682 square kilometres of exploration claims. During the 1980s certain sections of Blue Lake project were explored by La Fosse Platinum. They drilled hundreds of exploration holes, excavated a 350-metre (1,000-foot) adit, conducted geochemical, geophysical and geologic surveys, and metallurgy testing. The surface projection of discovered mineralization as well as historical drill locations are shown and comprise an area less than 10 square kilometres.

The above figure's copper equivalence estimates were made using Canadian dollars for the copper equivalent calculation with metal prices as of Sept. 8, 2025, of $6.20/pound Cu (copper), $9.52/lb Ni (nickel), $1,921.60/oz Pt (platinum), $1,566.82/oz Pd (palladium). Equation used: copper equivalent equals Cu (per cent) plus (Ni (per cent) multiplied by 1.54) plus (Pt (g/t) multiplied by 0.45) plus (Pd (g/t) multiplied by 0.37). There is a reasonable assumption that recoveries will be 80 per cent or more for all commodities, consistent with comparable peers, and all Cu equivalent numbers were multiplied by this factor. A search for metal recoveries was conducted for the main Ni-Cu deposits and recoveries are usually higher than 80 per cent for Ni and Cu. Only copper equivalence values calculated above 0.4 per cent are shown on the figure.
