Trailbreaker Resources Ltd. (TBK.V)
(“Trailbreaker” or “the Company”) is pleased to report geochemical
results from the 2023 surficial exploration program at their Castle
Rock property on northern Vancouver Island, British Columbia (BC).
Highlights from the surficial exploration
program include:
- Definition of a
3 km gold-in-soil geochemical anomaly along a
magnetic lineament, including the newly defined Kokummi and
Watchtower zones;
- Rock samples
assaying up to 42.1 g/t gold (Au) and 1.93% Copper
(Cu) at the Flan zone, confirming historic results;
- Extension
of the Heart zone in outcrop, with rock sample results up
to 2.21 g/t Au (175 m north of the Heart showing) and 2.18 g/t Au
(80 m east of it);
- Moss-mat sampling
indicates gold mineralization may occur in drainages where no
previous exploration has occurred;
- Interpretation of
magnetic lineaments suggests that mineralization is associated with
northwest trending structures splaying off the Kokummi
granodioritic stock in the southwest property area. This indicates
much of the unexplored property areas may have elevated mineral
potential.
Message from the President
“Our grassroots exploration efforts at Castle
Rock have continued to build upon a showing with limited previous
exploration, and are quickly developing this into a compelling
project with multiple targets. Castle Rock is a great testament to
our tried-and-true exploration methodology which has proven to add
value to our portfolio of early-stage exploration projects. We are
excited to continue to advance Castle Rock, along with the rest of
our portfolio.” – Daithi Mac Gearailt

Sampling defines a 3 km gold-in-soil trend which includes the Heart
zone and newly defined Watchtower and Kokummi zones. Rock sampling
has confirmed historic values at the Flan zone and defined an open
gold-in-soil anomaly. Additionally, anomalous moss-mat samples in
the southeast and eastern portions of the property have defined new
areas of potential mineralization, leading to additional claim
staking.
Heart, Watchtower, and Kokummi zones (3
km long soil trend)
Rock and soil geochemical sampling and
prospecting successfully defined a three-kilometre gold-in-soil
trend with multiple >30 ppb gold anomalies, centered on the
previously known Heart showing. The Heart showing was discovered in
2012 and consists of a brecciated granodiorite dyke containing 5 to
10% pyrite-chalcopyrite. Historic chip sampling returned assays of
2.0 g/t Au over 30 metres1.
During the 2023 surface campaign, rock samples
collected from an outcrop 175 m north-northwest of the Heart
showing returned assay results up to 2.2 g/t Au. These samples were
collected from a strongly oxidized granite, very similar to the
main Heart zone showing. Additionally, gossanous basalt containing
pyrite was sampled in outcrop 80 m east-northeast of the Heart
showing, and returned assay results up to 2.2 g/t Au.
Soil sampling near the Heart showing expanded
the continuous gold-in-soil anomaly, defining the Heart zone to
approximately 1,150 m in strike length and up to 300 m in
width.
A new multi-sample gold-in-soil anomaly, the
Watchtower zone, was identified approximately 325 m to the
southwest of the Heart showing. No previous sampling had been
conducted in the area prior to 2023. The anomaly remains open to
the south and west. This may represent an additional mineralization
centre near the Heart zone.
A second newly identified gold-in-soil anomaly,
the Kokummi zone, was defined to the south-southeast of the Heart
zone. This anomaly is on strike of the Heart zone and is defined by
gold-in-soil values >30 ppb along multiple soil sampling lines,
defining a >600 m strike length.
Flan zone
Historic sampling at the Flan zone returned
assays up to 135 g/t Au in boulders2. Sampling during 2023 was
designed to confirm the presence of mineralization and to define a
bedrock source. Gossanous float material sampled at the Flan zone
confirmed high-grade gold mineralization, with assays up to 42.1
g/t Au and 1.93% Cu. As well, basalt-hosted semi-massive
pyrite-chalcopyrite-pyrrhotite sampled in outcrop returned assays
up to 3.1 g/t Au. It is believed that this outcrop-hosted
mineralization is associated with the float samples, and that
similar mineralization may occur under vegetative and/or till
cover. The Flan zone lies at the intersection of two magnetic
lineaments. This structural intersection may be an important
control of gold mineralization.
The Flan zone occurs on the western extent of
the soil geochemical grid. However, another gold-in-soil anomaly
was defined from the 2023 sampling approximately 500 m north of the
outcrop mineralization at the Flan zone. The anomaly is defined by
>30 ppb gold-in-soil, and remains open to the west and
north.
Reconnaissance sampling
To assess potential mineralization outside of
the primary area covered by soil sampling, moss-mat sampling,
targeting additional drainages on the property, was employed.
Moss-mat sampling is used as a reconnaissance style sampling
method, similar to stream sediment sampling, providing indications
of metal content within a drainage and providing a vector for the
location of mineralization.
Two areas returned multiple moss-mat samples
with greater than 10 ppb gold. The first area is in the
southeastern portion of the property, near the postulated contact
of the Kokummi stock and the Karmutsen basalts. The second area is
within a valley that drains from the eastern flank of Mt. Adam.
This valley, which has not undergone any exploration work, is
marked by magnetic lineaments, similar to those at the
Heart-Kokummi soil trend. Additional claims were staked in this
area to cover all drainages potentially causing these elevated
moss-mat samples.
Future Work Recommendations
Future work at the Castle Rock property will be
focussed toward continuing to define the extent of mineral
potential on the property, as well as advancing individual targets
toward initial drill testing. This work will include permitting to
conduct advanced exploration activities, additional surface
geochemical work, and geophysical surveying.
About the Castle Rock
property
The Castle Rock property covers 3,108 hectares
of land, approximately 70 km northwest of Campbell River, BC
on northern Vancouver Island (Figure 1). It was acquired by
Trailbreaker in 2022 and was recently consolidated through an
option agreement with Cazador Resources Ltd. (see August 8, 2023
news release). Trailbreaker conducted initial exploration
assessment work in 2022 and followed up with a second surface
exploration program in 2023 (results are contained in this news
release).
The claims cover five BC Minfile occurrences on
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 Cu-Au porphyry deposits, including Northisle’s Hushamu
deposit (Inferred Resource of 5.57 Moz AuEq)3, and BHP Billiton’s
past producing Island Copper porphyry copper deposit (produced
>2.7 B lb Cu and >1.0 Moz Au) 3.
At the Castle Rock property, gold is dominantly
hosted in Jurassic granodiorite dykes which have been emplaced
along a regional-scale fault zone separating Lower to Middle
Triassic Daonella Bed sedimentary rocks from Upper Triassic
Karmutsen Formation basalts.
