Winter drilling extends known mineralisation

About this update from Cupani Metals Corp.

TORONTO, April 29, 2026 /CNW/ - Cupani Metals Corporation ("Cupani" or the "Company") (CSE: CUPA) (OTCQB: CUPIF) is pleased to announce some early success in its exploration campaign being conducted on its 100%-owned Blue Lake project. The main objective of the program was to test the interpreted extension of the Blue Lake mineralisation to the South-East within the High-Potential Corridor (click: 27 February 2026 press release for description). The new geological interpretation was confirmed by the intersection of massive sulphides at the base of a sub-horizontal ultramafic unit. Cupani has drilled 6 holes for a total of 1,344 meters. The drilling program commenced on March 18th and was paused last week for goose hunting season until June, as agreed in advance with the Naskapi Nation of Kawawachikamach. A total of 803 core samples, including 10% QA/QC samples, has been sent to the ALS Global in Val D'Or for processing. Four holes were drilled in the Blue Lake South-east sector (figure 1). These holes all targeted combined magnetic and electromagnetic anomalies. At the base of the ultramafic units, massive sulphides with sharp contacts to lithologies were identified over lengths of up to two meters. Above the massive sulphides, the ultramafic rocks usually contain 5 to 20% disseminated, net textured and blebby sulphides over thicknesses of up to 70 meters. The furthest hole to date is 1.4 kilometres from the southern edge of historical deposit / lens named Blue Lake #2. This extends the footprint of known mineralization to the southeast. Cupani management now believes the entire length of this Corridor (16 km) could hold mineralization similar to, or better than, what is observed at the Blue Lake mineralised lenses (1 to 6). Cupani has chosen to keep the drill rig onsite to resume drilling during the Summer. Cupani CEO Brian Bosse offers the following comment about these initial results "This first Cupani drilling program clearly confirmed that the mineralisation extends to the Southeast in an area that was never drilled properly. It demonstrates the validity of our new geological interpretation defining a sub-horizontal shallow, easy to drill, High-Potential Corridor extending some 16 kilometers to the south-east from the known Blue Lake 1-6 mineralised lenses". Brian Bosse will take questions online at 4pmEST on 30 Apri...
