Trailbreaker Resources Ltd. completed a surficial exploration program at its Castle Rock property on northern Vancouver Island, British Columbia (BC). The program consisted of the collection of 497 soil samples, 50 prospecting grab samples, and geological mapping. It was primarily designed to follow up on the channel sample and associated 400 m x 50 m gold-in-soil anomaly defined as the Heart zone in 2022.

The Castle Rock property covers 3,108 hectares on Northern Vancouver Island, approximately 70 km northwest of Campbell River, BC. It was acquired by Trailbreaker in 2022 and was recently consolidated through an option agreement. The claims cover five BC Minfile occurrences along a district-scale structure that is >5 km long, with newly identified gold ± copper-enriched intrusions.

These Minfile occurrences are relatively new discoveries, mostly due to access created by recent logging activity. Northern Vancouver Island is host to several large copper-gold (Cu-Au) porphyry deposits including Northisle?s Hushamu deposit (Inferred Resource of 5.57 Moz AuEq)1, and BHP Billiton?s past producing Island Copper porphyry copper deposit (has produced >2.7 B lb Cu and >1.0 Moz Au) 1. At the Castle Rock property, gold is dominantly hosted in Jurassic granodiorite dykes emplaced along a regional-scale fault zone separating Lower to Middle Triassic Daonella Bed sedimentary rocks from Upper Triassic Karmutsen Formation basalts. The soil survey was also extended to cover the Flan zone, located approximately 1.5 km west of the Heart zone.

The zone was originally discovered in 2000 and comprises numerous high-grade boulders assaying up to 135 g/t Au3. Prospecting at the Flan zone during the 2023 program uncovered significant pyrrhotite-chalcopyrite mineralization hosted in a mafic volcanic unit. While the boulders were originally interpreted as sourced from the Heart zone, the mineralized volcanic rocks may represent a recently exposed bedrock source discovered in 2023 within 200 metres of the historic location of the boulders.
