Catch Copper-Gold Porphyry Project Drilling Update

VANCOUVER - Cascadia Minerals Ltd. reported on the ongoing diamond drill program at its Catch Property. The Catch Property hosts one of North America's newest copper-gold porphyry discoveries, with extensive mineralization at surface. The property is located in central Yukon, only 10 km from a paved all-season highway and powerline, within an extension of the Stikine terrane – a key geological setting which extends from the Golden Triangle in British Columbia to Yukon. The Catch Property has never been historically explored, with Cascadia conducting the first-ever diamond drill program in fall 2023, which resulted in the discovery of the Spark Zone.

The first 2024 diamond drill hole (CA-24-006) stepped out 315 m from 2023 discovery hole CA-23-002 and intersected 140 m of pyrite-chalcopyrite mineralization. Mineralization in CA-24-006 contains greater sulphide abundance (pyrite-chalcopyrite) than observed in hole CA-23-002, which returned 116.60 m of 0.31% copper with 0.30 g/t gold. CA-24-006 intersected zones of potassic alteration associated with disseminated and vein hosted chalcopyrite-pyrite. Hole CA-24-006 targeted a coincident Induced Polarization ("IP") chargeability and resistivity high within a larger and open-ended 1.4 km long IP chargeability anomaly. The second 2024 drill hole (CA-24-007) is now underway, testing a similar IP chargeability and resistivity high 150 m north of CA-23-002, and planning is underway to extend the 2024 drill program to step out on CA-24-006.

"We are very excited to have hit additional mineralization on such a large step-out from last year's discovery at the Spark Zone. The amount of observed sulphide minerals, coupled with the favourable alteration we are now seeing, clearly demonstrates that this is a large mineral system with significant copper-gold potential. Mineralization at Catch is suggestive of an Alkalic Porphyry, similar in nature to the Red Chris mine in Northern BC and the Cadia-Ridgeway system in Western Australia," said Graham Downs, President and CEO. "Our crews are working to quickly process this core and get assays underway as soon as possible, with several batches of core already at the lab. In the meantime, drilling continues at the Spark Zone, where extensive geophysical anomalies remain open in all directions. It is critical to remember that this is only the third drill hole ever completed at this kilometer-scale target, with both holes last year returning significant mineralization. We see great potential at Catch and are evaluating options to extend the drilling program to complete additional step-out holes."
