Catch Exploration Summary
- 2023 inaugural diamond drilling resulted in a copper-gold porphyry discovery at the Diorite Zone with Hole CA-23-002 intersecting 116.60 m of 0.31% copper and 0.30 g/t gold (see
November 16 news release for details); - Drilling at the
Main Zone (holes CA-23-003 to -005), located 2 km north of theDiorite Zone , intersected high-level porphyry alteration and anomalous copper-gold values, but has not yet identified the source of extensive copper-gold mineralization in a localized landslide; - Additional 227 contiguous claims recently staked to cover additional prospective ground, expanding the Catch property to 117 km2 in size;
- Drilling has yet to intersect significant potassic alteration, suggesting there is potential to discover higher copper and gold grades in untested areas in the core of the porphyry systems;
- Planning is underway for an early 2024 follow-up diamond drill program;
- Systematic property-wide soil sampling has identified numerous additional copper anomalies across the property, as far as 10 km away from the
Diorite Zone ; and - Cascadia will be showcasing Catch core at the upcoming
Vancouver Resource Investment Conference (Jan 21-22 ) and AME Roundup (Jan 22-25 ) inVancouver
"Following our successful 2023 exploration season we are eager to follow-up with an expanded program in 2024. We have already made a significant copper-gold discovery at the

Catch Property 2024 Exploration Plans
With the success of the 2023 inaugural diamond drill program and strong evidence for an extensive mineralizing system, Cascadia staked an additional 227 claims in the late fall, expanding the Catch Property by 46 km2 to a total of 117 km2. Planning work is underway for a follow-up drilling program to commence in spring 2024. If snowfall conditions are favourable, work is targeted to begin in late April or early May.
Preliminary plans call for a minimum of 5,000 m of diamond drilling at Catch in 2024. The first priority will be to drill follow-up holes at the Diorite Zone, building on discovery hole CA-23-002, which intersected 116.60 m of 0.31% copper and 0.30 g/t gold. As this hole intersected significant grades in higher-level sodic and propylitic alteration, 2024 drilling will target significant step-outs both laterally and at depth, in areas with strong geophysical anomalies (Figures 2-3), vectoring towards the potassic core of the system (Figure 5).
Drilling in 2023 at the Diorite Zone was completed on only the western-most IP section line, where numerous outcrops returned strong copper grades coincident with a chargeability anomaly at depth (Figure 2). A significantly broader and stronger IP anomaly is located 300 m east (Figure 3), in an area with limited outcrop exposure. The diamond drill was over-wintered on an un-drilled pad in the middle of this eastern IP section, and 2024 work will commence with several deep holes in this area, as well as under-cuts of the 2023 drill holes.

Catch Property 2023 Exploration Overview
The inaugural diamond drilling program at the Catch Property was completed in 2023. A total of 5 holes were drilled, totalling 2,461.83 m. The first two holes were drilled at the

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 at the Diorite Zone 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 (Figure 5). 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 multiple directions.
Holes CA-23-003 to -005 at the Main Zone intersected broad zones of propylitic alteration throughout, as well as evidence of major structures. Hole CA-23-003 encountered the highest abundance of veining and sulphides, with the most anomalous copper-gold response of the three holes drilled in this area. This hole encountered several faults which returned elevated copper, including 0.16% copper and 0.29 g/t gold over 1.00 m from 274.00 m, 0.15% copper over 3.36 m from 205.65 m, and 0.12% copper over 1.47 m from 226.53 m, suggesting mineralization may be leaking upwards from a source located at depth. CA-23-003 was located furthest upslope in the landslide area, indicating the source of surface mineralization may be further upslope than anticipated. The IP chargeability response at the Main Zone (Figure 4) was largely explained by zones of pyrrhotite and pyrite mineralization, and several structures. It is likely that the main porphyry target lies below the depth of the current IP survey.

Property Geology and Mineralization
The 117 km2 Catch Property is located in central
The Catch area is mostly underlain by augite phyric basalt of the Semenof Formation, centered on a 7 x 3 km regional magnetic high. Mineralization is associated with propylitic to sodic alteration of basalt and lesser diorite, intrusion-cemented and hydrothermal breccias. Locally there is intense albitization, silicification, brecciation and up to 10% disseminated to blebby pyrite, chalcopyrite and trace bornite and pyrrhotite. Secondary copper minerals including malachite, azurite and tenorite are widespread at surface, coat fracture surfaces, and are often associated with gypsum.
The geology, alteration and mineralization observed throughout Catch are all indicative of a significant copper-gold ± molybdenum bearing porphyry system.
