Cascadia Steps Out 315 m at Catch and Intersects 106 m of Porphyry Mineralization Grading 0.37% Copper and 0.22 g/t Gold (0.52% CuEq)
Spark Zone Drilling Highlights
- Hole CA-24-006 intersected 106.00 m of 0.37% copper with 0.22 g/t gold (0.52% CuEq), within a broader interval of 177.00 m of 0.25% copper and 0.14 g/t gold (0.34% CuEq) (Figures 2,4);
- All five holes drilled to date at the
Spark Zone have encountered porphyry mineralization across 470 m of strike length and 520 m of vertical extent from surface, within an open-ended 1.2 x 1.0 km Induced Polarization chargeability high target (Figure 2); - Hole CA-24-006 was a 315 m step-out from the 2023 discovery hole CA-23-002 (Figure 2);
- An interval of potassic alteration in Hole CA-24-006 returned 0.67% copper with 0.87 g/t gold (1.25% CuEq)over 6.55m (Figures 5, 6), confirming higher-grade mineralization is present in the core of the system;
- Hole CA-24-007 encountered lower-grade mineralization in the pyrite-dominant outer shell of the porphyry system for nearly its entire length, returning 578.85 m of 0.10% copper (Figure 3);
-
A follow-up 1,500 m+ Phase 2 drill program is underway at Catch, with further step outs to the southeast at the
Spark Zone targeting broader zones of potassic alteration and the core of the porphyry system (Figure 2); and -
Initial prospecting results from the
Amp Zone (1 km north of theSpark Zone ) are very encouraging; results to be released within the week.

CA-24-006 was collared 315 m southeast of hole CA-23-002 (Figure 2), 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 feldspar porphyry, diorite, diorite porphyry, basalt and gabbro. The top 252 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 zone of sericitic (quartz-sericite-pyrite) to potassic alteration (shreddy biotite often replaced by chlorite) with disseminated to vein hosted pyrite-chalcopyrite mineralization from 252 to 429 m returned 177 m of 0.25% copper and 0.14 g/t gold in all host rock types. Potassic alteration was observed from 352.00 to 358.55 m and returned 6.55 m of0.67% copper and 0.87 g/t gold (Figure 5, 6). Strong propylitic alteration was observed again from 429 to 570 m dominantly within gabbro before encountering a large fault towards end of hole.
Hole CA-24-007 was collared from the same pad as CA-23-002 and drilled eastward to step out on copper-gold mineralization at depth. This hole encountered dominantly diorite with the highest abundance of pyrite observed in all holes at
CA-24-008 was collared from the same pad as CA-24-006 and drilled northeast to test a potential up-dip extension of the mineralization observed in hole CA-24-006. Broad intervals of lower-grade copper mineralization were returned, including 217.05 m of 0.10% copper from 195.95 to 413.00 m, ending in mineralization (Figure 4). These results support the interpretation that the core of the system lies southeast of drilling completed to-date.
There is a pervasive late-stage chlorite-sericite-clay overprint on the mineralization making identification of primary alteration difficult. In addition, structural deformation is observed in 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. Indications are that there may be multiple overlapping porphyry events present.
