Cascadia Provides Drilling Update for its Catch Copper-Gold Porphyry Project, Yukon
- 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 (Figure 1);
- 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 alterationassociated withdisseminated (Figure 2) and vein hosted chalcopyrite-pyrite (Figure 3);
- 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 (Figure 4);
- 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 (Figure 5); 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

Cascadia cautions that visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Laboratory assays are required to determine the presence and grade of any contained mineralization within the reported visual intersections of copper sulphides. The company will update the market as soon as laboratory analytical results become available.
Diamond drilling is underway at the
CA-24-006 was collared 315 m southeast of hole CA-23-002 (figure 1), targeting a stronger and broader portion of the IP chargeability anomaly (figure 4), coincident with a zone of high resistivity. The hole encountered a variety of host rock types including quartz-feldspar porphyry, diorite, diorite porphyry, basalt and gabbro. The top 290 m of the hole displayed broad propylitic alteration (chlorite-epidote-pyrite ± hematite) of dominantly basalt and diorite with a clear increase in intensity with depth. A 140 m zone of sericitic (quartz-sericite-pyrite) to potassic alteration (biotite) with disseminated to vein hosted pyrite-chalcopyrite mineralization was encountered from 290 to 430 m in all host rock types. Strong propylitic alteration was observed again from 430 to 550 m dominantly within gabbro before encountering a large fault towards end of hole.
There is a pervasive late-stage chlorite overprint on the mineralization making identification of primary alteration difficult. In addition, structural deformation deforms the mineralization; likely from the nearby 1,000+ km long Teslin-Thibert fault. Further petrographic studies will be undertaken in the coming months to validate initial geology and alteration logs.
Hole CA-24-007 is collared off the same drill pad as CA-23-002 and will fan eastward and step out 150 m on the known copper-gold mineralization at depth. This hole will test the projected extension of mineralization from hole CA-23-002 towards an area of high IP chargeability and stronger resistivity (figure 5), which may represent potassic alteration.
