Copper and gold galore for Cascadia Minerals

Throughout 2024, Cascadia Minerals Ltd. made significant strides at its flagship Catch copper-gold project in Yukon, Canada, uncovering high-grade copper intercepts and new gold targets while advancing other promising properties and ultimately reinforcing its position as a leader in Yukon copper exploration.

Located about 56 kilometers (35 miles) southeast of Carmacks, the Catch property spans 117 square kilometers (45 square miles) within an underexplored region of southcentral Yukon known for its porphyry copper-gold potential.

In addition to Catch, Cascadia's portfolio includes several properties in close proximity, such as Rosy, Idaho Creek, Mack's, and Milner. The company also holds the Sands of Time property adjacent to Western Copper and Gold's Casino project, along with PIL in British Columbia's Toodoggone region.

Following its reemergence as a copper-focused explorer in 2023 – after selling core gold properties to Hecla Mining Company – Cascadia embarked on its first full exploration season at Catch and other promising properties.

Building on initial discoveries made in 2023, the company launched an ambitious program in 2024 aimed at expanding known mineralization and uncovering new targets critical to the energy transition.

This program included 1,200 meters of diamond drilling, primarily focused on step-out drilling at the Spark Zone, one of the main targets at Catch, along with other high-priority targets identified through geophysics and surface sampling.

During the first phase, a strategic 315-meter step-out from the original discovery hole at Spark intersected high-grade copper over substantial widths. Highlights included:

• 177 meters averaging 0.25% copper and 0.14 g/t gold from a depth of 252 meters in hole CA-24-006; this included a significant intercept of 106 meters averaging 0.37% copper and 0.22 g/t gold from 309 meters.

• 579 meters averaging 0.1% copper and 0.01 g/t gold from 51 meters in CA-24-007, including a long stretch of 103 meters averaging 0.22% copper and 0.04 g/t gold.

• 217 meters averaging 0.1% copper and 0.02 g/t gold from 196 meters in CA-24-008, including 31 meters averaging 0.25% copper and 0.02 g/t gold from 196 meters.

"To have stepped out over 300 meters from our discovery hole at the Spark Zone and hit higher grade copper over a significant width is incredibly positive and a testament to the size and strength of the system," said Cascadia Minerals President and CEO Graham Downs. "All three of the holes drilled this spring achieved our goal of intersecting porphyry copper-gold mineralization and critical alteration data, which will help us vector towards the core of the system and target broader zones of higher grade potassic alteration."

These results prompted a phase-two program with an additional 1,500 meters of drilling aimed at deeper and step-out targets in the southeast, advancing toward the interpreted core of the porphyry system.

While initial drilling at Spark delivered strong results, it was the later-season prospecting at the Amp Zone, about 1,000 meters north of Spark, that unveiled even more impressive mineralization. This newly identified target yielded bonanza-grade samples, including a 0.9-kilogram outcrop grading 1,065 g/t gold and 267 g/t silver.

This discovery marked a new epithermal gold-silver target within the broader Catch property, underscoring its district-scale potential.

"The discovery of such high-grade epithermal gold mineralization over one kilometer north of a new drill-confirmed porphyry discovery is a significant development for us," said Downs. "Epithermal gold-silver mineralization is often associated with porphyry systems but not always preserved. The Amp Zone represents another distinct target on this district-scale property."

Alongside Catch, Cascadia conducted property-wide surveys at nearby prospects like Rosy, Idaho Creek, Mack's, and Milner, as well as initial exploration at Sands of Time, refining targets for future drilling.

Last year's field programs at Mack's, Milner, and Sands of Time confirmed promising copper-gold anomalies, refining targets for future campaigns. As 2024 came to a close, Cascadia outlined its plans for 2025, which include expanding drilling efforts at Catch, particularly at Spark and the newly identified Amp Zone, while continuing exploration across its portfolio of properties in the Yukon and British Columbia.
