Trailbreaker Resources Ltd. has announced that it has acquired Castle Rock property on northern Vancouver Island, British Columbia (BC).
Claim staking was used to acquire the property, and in January 2023, Cazador Resources Ltd. formed a partnership to further develop it. There are no underlying payments or royalties involved; the companies collectively own the entire piece of property.
Trailbreaker finished a first-pass prospecting program at the Castle Rock claims in September 2022. The program, which included channel sampling, prospecting, and soil sampling, was created to follow up on historical values.
Highlights of the Castle Rock property
- Covers 3,108 hectares of land on northern Vancouver Island, approximately 70 km northwest of Campbell River, BC
- Claims cover 5 Minfile occurrences, >5 km-long district-scale structure, and newly identified gold +/- copper-enriched intrusions
- A relatively new discovery, in an area that hosts copper-gold (Cu-Au) porphyry, volcanogenic massive sulfide (VMS), and gold skarn deposits
- Northern Vancouver Island is host to several large Cu-Au porphyry deposits including Northisle’s Hushamu deposit (Inferred Resource of 5.57 Moz AuEq), and BHP Billiton’s past producing Island Copper deposit (produced >2.7 B lb Cu and >1.0 Moz Au)
- Vancouver Island is host to the Myra Falls VMS deposit (>1.5 Moz Au past production) and the Merry Widow gold skarn deposit (>200 Koz Au past production)
- Newly accessible via recent logging activity
- Historic chip sample returned assays of 2.0 g/t Au over 30 m
- Historic grab sampling from boulders returned assays up to 135 g/t Au, 1.5 km west of Heart showing (source: Flan Minfile, 2007)
- Along a regional-scale fault zone dividing Upper Triassic Karmutsen Formation basalts from Lower to Middle Triassic Daonella Bed sediments, gold is hosted in Jurassic granodiorite dykes that have been erected along the fault zone
The Castle Rock property is Trailbreaker’s newest addition to our portfolio of high-quality precious metal and copper assets. This is an overlooked and underexplored area of Vancouver Island that has recently been made more accessible. With a short geochemical sampling and reconnaissance program, the team was able to delineate a large, gold-bearing dyke system over at least 400 m, coinciding with a district-scale fault. This system has strong potential for expansion.

Partnership with Cazador Resources
Trailbreaker and Cazador Resources Ltd. entered into a partnership agreement in January 2023. The effectiveness of upcoming exploration in the Schoen Creek region, including the Castle Rock property, will be improved by this partnership. The agreement’s specifics are as follows:
- Each party owns 50% of the property
- All agreed-upon expenses incurred and potential proceeds will be split between the parties.
- All information will be shared between the parties to enhance the development of the property.
- The agreement is perpetual unless terminated by mutual consent of both parties.
Trailbreaker Resources’ 2022 Exploration Program
Trailbreaker finished a first-pass, 3-day evaluation program on the Castle Rock claims in September 2022.
The program included a thorough 116-sample soil sample survey as well as 32 m of channel sampling intended to verify the historic grades and thickness. In 2022, values up to 0.680 g/t Au over 13.11 m, including a subinterval of 1.85 g/t Au over 2.92 m, were successfully confirmed by the program, confirming historic gold grades.
A 50 m × 400 m gold-in-soil anomaly with a northwest-southeast trend was identified in the soil sample survey, and it was assumed to be the surface footprint of the gold-bearing dyke exposed at the Heart showing. The anomaly is still open, and the soil values peaked at 5.44 g/t Au.
Future Exploration at Castle Rock
On the property, no systematic geochemical or geophysical work has ever been done. To further develop the Heart zone and locate additional mineralized intrusive dykes, Trailbreaker intends to conduct a geochemical soil survey across the entire property.
With samples returning up to 860 ppb Au that has not yet been the subject of further exploration, historical silt sampling has identified additional targets on the property.
Additionally, 1.5 km west of the Heart showing, a second historic gold showing known as the Flan showing was founded in 2000. It consists of numerous high-grade boulders with gold assays up to 135 g/Au.
These boulders are thought to have originated from the upstream Heart showing. This suggests that the Heart zone could contain much higher-grade gold mineralization than has been previously discovered.
The Castle Rock project, in the opinion of Trailbreaker’s team, is a fascinating discovery that has previously gone unnoticed. Given its proximity to significant district-scale structures and open-ended anomalies, it has the potential to develop quickly into a significant gold prospect.
Message from the President
Daithi Mac Gearailt added, “The Castle Rock property represents Trailbreaker’s continued focus as a project generator. We are very excited to sink our teeth into exploring a new gold district. The completed program has shown this to be a large mineralized system, with plenty of opportunity for new discoveries. The team, including myself, along with the team at Cazador Resources, will be diligently planning the next steps for this project.”
