Cascadia Minerals Ltd. provided results of the first two diamond drill holes ever completed at its 100%-controlled Catch Property in central Yukon, Canada, located 16 km from an all-season highway and powerline within the traditional territory of the Little Salmon Carmacks First Nation. The Catch Property hosts multiple new greenfield discoveries of copper-gold porphyry mineralization within the northern extension of the prolific Stikine Terrane from BC's Golden Triangle. A total of five holes were drilled at Catch in 2023, totalling 2,462 m. This release contains results from the first two holes (1,066 m), with results from the remaining three holes pending.

The first two diamond drill holes at the Catch Property were completed at the Diorite Zone. Hole CA-23-001 ended at 511.83 m depth and Hole CA-23-002 ended at 554.00 m depth, with sulphide mineralization (pyrite-pyrrhotite-chalcopyrite) observed to the end of both holes. Both holes were targeting a broad Induced Polarization ("IP") chargeability anomaly at depth, underlying coincident high-grade surface mineralization, within a pronounced magnetic anomaly.

An additional three holes were drilled at the Main Zone, located 2 km north, and results from these holes are pending. Hole CA-23-001 targeted a high IP chargeability anomaly underlying an outcrop which returned 0.31% copper with 0.17 g/t gold over 12 m from a hand trench. The hole encountered basalt, diorite and gabbro host rocks.

Copper and gold mineralization is associated with propylitic (chlorite-albite-epidote-calcite) to sodic (albite-chlorite-pyrite) alteration of all host rock types that carry quartz-carbonate ± pyrite-chalcopyrite veins and disseminated to blebby pyrite, pyrrhotite and chalcopyrite (sulphides listed in decreasing order of abundance). The hole ended in anomalous copper grades, with visual pyrrhotite and pyrite mineralization noted. Hole CA-23-002 was collared 160 m north of CA-23-001, targeting the same high IP chargeability anomaly, underneath an outcrop which returned high-grade grab samples including 3.88% copper with 30.00 g/t gold.

The hole encountered similar rock types, alteration and mineralization to hole 001, in addition to localised quartz-feldspar porphyry dykes up to 17 m in width, and an overall increase in copper and gold grades. The hole ended in anomalous copper grades, with visual pyrrhotite and pyrite mineralization noted. Drilling has not yet intersected significant potassic alteration, suggesting there is potential to discover higher copper and gold grades associated with the potassic core of the system.

Additional drilling will be required to vector towards this core. Both holes were drilled in the middle of a coincident 1,200 x 600 m high IP chargeability anomaly and 800 x 600 m magnetic low anomaly. These geophysical features have provided a valuable vector towards mineralization and remain open in all directions.
