Trailbreaker Resources Completes Exploration Program at Castle Rock Property, Northern Vancouver Island

VANCOUVER, British Columbia, Sept. 25, 2023 (GLOBE NEWSWIRE) -- Trailbreaker Resources Ltd. (TBK.V) (“Trailbreaker” or “the Company”) is pleased to announce that it has 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.

Daithi Mac Gearailt, CEO of Trailbreaker, commented: “The program provided excellent coverage of the already robust gold anomaly at the Heart zone. This is a very recent discovery in an underexplored area of the Island. With the results in hand, we will have a more complete picture of the strike length of the anomaly and whether there are additional geochemical trends.”

All assays for the program remain pending.

About the Castle Rock property

The Castle Rock property covers 3,108 hectares on Northern Vancouver Island, approximately 70 km northwest of Campbell River, BC (Figure 1). It was acquired by Trailbreaker in 2022 and was recently consolidated through an option agreement (see August 8, 2023 news release).

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.

2023 exploration at the Heart and Flan zones

The Heart zone was the primary focus of the 2023 exploration program. The Heart showing (upon which the zone is centered) was discovered in 2012 and consists of a brecciated granodiorite dyke containing 5% to 10% combined pyrite and chalcopyrite. Historic chip sampling returned assays of 2.0 g/t Au over 30 metres².
