Cascadia Samples 1,065 g/t Gold and 267 g/t Silver in Outcrop at the Amp Epithermal Zone, Catch Property, Yukon
Catch Prospecting Highlights
- Prospecting at the
Amp Zone , located 1 km north of the recently released drilling at theSpark Zone , returned the highest gold and silver gradeson the project to-date, including a 0.9 kg outcrop sample which returned1,065 g/t gold and 267 g/t silver (Figures 1, 2); - A second sample from a different portion of the same outcrop returned 47.2 g/t gold and 19.3 g/t silver in a 1.4 kg sample (Figure 3);
- The mineralization is associated with strong silicification, abundant pyrite and quartz-calcite veins and provides evidence of a large and fully preserved epithermal target associated with the nearby porphyry system;
- An expanded IP survey is scheduled to commence shortly, which will extend coverage over the
Amp Zone to aid in future diamond drill targeting; and - Prospecting crews are on-site to conduct follow-up work at the
Amp Zone and elsewhere on the property.
"The discovery of such high-grade epithermal gold mineralization over 1 km north of a new drill-confirmed porphyry discovery is a significant development for us. Epithermal gold-silver mineralization is often associated with porphyry systems but not always preserved.

Amp Zone Prospecting Results
The 2024 Phase 1 exploration program at Catch comprised prospecting, mapping, and diamond drilling. Three diamond drill holes totaling 1,613 meters were drilled at the
Follow up prospecting focused on the
In 2023, prospecting samples at Amp returned 0.21% copper with 4.82 g/t gold from outcrop. Follow up work in 2024 at the same outcrop returned 1,065 g/t gold with 267 g/t silver (0.9 kg sample) and 47.2 g/t gold with 19.3 g/t silver (1.4 kg sample). The gold-silver mineralization is hosted within a highly silicified basalt with up to 10% pyrite and is associated with elevated arsenic and antimony geochemistry, suggesting it is epithermal in nature.
Previous Induced Polarization ("IP") geophysical surveys were focused on the Spark and Volt Zones, and did not provide coverage at the

Catch Property Geology and Mineralization
The 119 km2 Catch Property is located in central
Catch is mostly underlain by augite phyric basalt of the Semenof Formation, centered on a 7 x 3 km regional magnetic high. Copper gold porphyry mineralization is associated with potassic to sericitic alteration of basalt, diorite, feldspar porphyry and gabbro and lesser intrusion breccias and hydrothermal breccias. Secondary copper minerals including malachite, azurite and tenorite are widespread at surface, and coat fracture surfaces.
Catch is under option from a
QA/QC
Analytical work for rock samples was completed by
Overlimit values for gold were determined by the Au-GRA21 procedure which involves fire assay preparation using a 30-gram charge with a gravimetric finish. Overlimit values for copper and silver were determined by the Cu-OG62 and Ag-OG62 procedures which involve a four-acid digestion followed by ICP-AES analysis.
Gold samples assaying over 30 g/t gold were re-analyzed with the Au-SCR21 technique, which involves screening of 1 kg of pulverized sample at 100 microns. Oversize material was analyzed in entirety by fire assay with gravimetric finish. Undersize material was analyzed in duplicate by fire assay with atomic absorption spectroscopy finish. Results of the oversize and undersize assays were combined to provide the final reported numbers provided in this release.
Results referenced in this release represent highlight results only. Below detection values for gold and copper have been encountered in soil and rock samples in these target areas.
