October 15, 2024 – Trailbreaker Resources Ltd. (TBK.V) (“Trailbreaker” or “the Company”) is pleased to announce the mobilization of geophysical crews from Geotech Ltd. and Simcoe Geoscience Ltd. (“Simcoe”) to conduct Z-axis Tipper Electromagnetic (ZTEM) and induced polarization (IP) surveys, respectively, at the Liberty copper (Cu) – molybdenum (Mo) project, in central British Columbia (BC).
The ZTEM survey is designed to provide property-wide resistivity and magnetic data up to a depth of 1,500 m. This will help define the geological, structural and alteration features of porphyry and skarn-style mineralization, of which previous grab samples assayed up to 23.71% Cu.
The IP survey is being conducted over the Cu-in-soil anomaly (see news release September 16, 2024) in order to define the extensions of historic chargeability and resistivity features that are coincident with Cu‑Mo mineralization intersected during Trailbreaker’s 2,442 m drill program conducted earlier this year (see news release dated July 22, 2024). The survey will utilize Simcoe’s Alpha IPTM technology to survey up to 500+ m of depth, ensuring any deep sources of mineralization are detected.
Results and interpretation from both surveys are expected before the end of 2024.
Message from the President “We are excited that these surveys have commenced at Liberty. The surveys extend deep below the overburden on the property. When these results are coupled with what we have learned from drilling, together with our property-wide geochemical survey and the high-grade Cu in rock samples, we expect it to produce a robust geological model to help vector and de-risk future drilling. This project is advancing quickly and in the right direction for a discovery.” Daithi Mac Gearailt

Liberty Property Description The 6,895-hectare Liberty Property is located approximately 60 km northwest of Quesnel, BC. The property is fully accessible by resource roads.
Drilling at Liberty has encountered widespread Cu-Mo porphyry-style mineralization at the northeastern margin of a property-scale Cu-in-soil geochemical anomaly. Mineralization is coincident with an Induced Polarization (IP) chargeability feature. However, historic IP surveying covered only a small portion of the much larger geochemical anomaly. Highlights of drill results include:
LIB24-001 – 213.7 m of 0.16% CuEq from 248.3 m to the end of hole;
Including 13.5 m of 0.33% CuEq from 257.5 m;
And including 6.6 m of 0.67% CuEq from 300.9 m;
LIB24-003 – 194.3 m of 0.16% CuEq from 256.0 m,
including 34.2 m of 0.47% CuEq from 385.0 m,
and including 5.9 m of 2.02% CuEq from 410.2 m;
LIB24-004 – 226.0 m of 0.11% CuEq from 279.0 to the end of hole
Including 6.0 m of 0.45% CuEq from 431.0 m
And including 2.3 m of 0.36% CuEq from 500.0 m
Prospecting within the southwestern portion of the property-scale geochemical anomaly has defined an area of high-grade copper mineralization, with grab samples assaying up to 23.71% Cu.
For more information on this target see the Liberty Project webpage.
* Reported widths are drill width. Not enough geological information exists at this point to define true width. However, vein- hosted copper and molybdenum mineralization commonly occurs at high angles to core axis.
** Copper Equivalent formula used is:
CuEq = Cu grade in % + (Mo grade in % * (Mo recovery/Cu recovery) * (Mo price/lb*2200 lb) / (Cu price /lb*2200 lb) using copper price of US$3.75/lb and molybdenum price of US$25/lb. 100% metallurgical recoveries are assumed for both metals.

October 7, 2024 – Trailbreaker Resources Ltd. (TBK.V) (“Trailbreaker” or “the Company”) is pleased to announce the delineation of a donut-shaped chargeability high feature (15-35 mV/V) from an induced polarization (IP) survey completed at the Swan zone. The Swan Zone is a gold (Au) – copper (Cu) – silver (Ag) porphyry target within Trailbreaker’s Atsutla Gold Project, northwestern British Columbia (BC). The IP chargeability high is coincident with a 900 m by 700 m Au-Ag ± Cu – molybdenum (Mo) soil and rock (grab samples assaying up to 11.7 g/t Au, 95 g/t Ag, and 0.81% Cu) geochemical anomaly within a zone of advanced argillic (clay mineral) alteration of a granodiorite stock.
In combination with a historic IP survey to the northwest, the 2024 IP survey defines a donut-shaped chargeability high feature, with external dimensions of approximately 2.1 km by 1.4 km (Figure 1). The thickness of the chargeability high is approximately 200 m to 500 m. The chargeability signature is strongest near-surface and extends to at least 300 m of depth. The southern portion of the chargeability high feature is correlated with a wider (~700 m) zone of low resistivity (<800 ohm-m) (Figure 2). The high chargeability anomaly may represent distribution of disseminated pyrite, and the low resistivity feature may be caused by alteration minerals, including sericite, pyrophyllite and clay minerals, identified during geological mapping. The combination of these features commonly occurs in the phyllic alteration assemblage surrounding porphyry deposits1.
Message from the President
“The IP survey at the Swan zone provides another layer of data which indicates we may be exploring the upper parts of an Au-Cu-Ag porphyry system. This is in conjunction with results from geological mapping and identification of a multi-element geochemical anomaly which occurs on a gossanous hill. 2024 has been a pivotal year for advancing the Swan zone, as we’ve also received an exploration permit that will allow us to further test this zone, including by diamond drilling.” – Daithi Mac Gearailt
Induced Polarization Survey Parameters
Trailbreaker contracted Aurora Geosciences Ltd. (Aurora) to complete an induced polarization survey on the Swan Au-Cu-Ag target at the Atsutla Gold project. The IP survey was designed to extend a historic (1976) IP survey that defined a semi-circular chargeability high feature (Figure 1). The survey also covers the Swan multi-element geochemical anomaly that was defined by Trailbreaker between 2021 and 2024.
A total of 21 line-kilometers were surveyed across seven 200-metre spaced IP lines, each 3 km in length, covering an area of 3.75 km2. The survey used an inline pole-dipole (2D survey) array with a 100-metre dipole spacing. The estimated depth of investigation of the survey is 300 m below surface.
Equipment used by Aurora for the IP survey included IRIS Instruments’ FullWaver System of 21 dual-channel voltage receivers (V-FullWaver) and two current receivers (I-FullWaver), as well as a GDD TX IV 5 kW IP transmitter powered by a 7 kW mobile generator. Stainless steel electrodes were used to provide ground contact, occasionally with the use of salt water to improve contact resistance in talus material.
Once collected, IP data underwent quality assurance and quality control (QA/QC) validation and data processing. Campbell & Walker Geophysics reviewed the validated data, completed inversions as 2D sections and interpolated the data to produce a pseudo 3D model, including a 3D voxel model, as well as iso-surfaces and depth slice maps.
Figure 1: Coincident geophysical, geochemical, and geological features on the Swan target. Data displayed includes: the 100 m depth slice of the interpolated chargeability data from the 2024 IP survey; the outline of the historic chargeability high shown to the northwest; interpretation of alteration zonation from 2022 geological mapping; Au and Ag-in-soil values from 2021-2023 (transparent) and 2024 (opaque). The chargeability high likely represents additional extensions of the phyllic alteration zone beyond the outcrop exposures mapped in 2022. The strong Au-in-soil anomaly is coincident with the advanced argillic alteration and an east-west break in chargeability which aligns with the secondary Au-in-soil anomaly to the east.
Figure 2: Data displayed includes: a 100 m depth slice of the interpolated resistivity data from the 2024 IP survey; Cu and Mo-in-soil values from 2021-2023 (transparent) and 2024 (opaque); the outline (black lines) of the historical and 2024 chargeability anomalies (>15 mV/V) and interpretation of alteration zonation from 2022 geological mapping. The resistivity low (red and pink) coincides with the southern portion of the chargeability high and the mapped phyllic alteration zone. Anomalous Mo-in-soil values extend beyond the Au-Ag-Cu soil geochemical anomaly.
Soil Sampling and Prospecting
A total of 1,165 soil and 28 rock samples were collected on the eastern side of the Atsutla Gold project concurrently with the completion of the IP survey. Soil sampling was completed on a north-south grid extension of previous Swan soil surveying, as well as along ridge and spurs of nearby mountains within the Upper Cretaceous Glundebery batholith.
Sampling extended the Swan multi-element soil anomaly 400 m to the west. In addition, sampling has improved definition of an Au-Ag ± Cu-in-soil anomaly ~1 km east of the Swan zone, and a pathfinder element anomaly, including arsenic (As) -bismuth (Bi) ± Mo ± Au ± Ag ± Cu, ~2 km across a valley to the west. These anomalies, including the Swan zone, define an east-west corridor of prospective geology across 4.5 km.
Prospecting on the southwestern side of the chargeability-resistivity anomaly focussed on an area of rock float containing quartz-veins with disseminated to blebby molybdenite ± chalcopyrite ± arsenopyrite (Figure 2&3). These samples may have originated from a porphyry hydrothermal system.
Figure 3: (a) Float sample (5233605) containing molybdenite along a fracture surface, assaying 326 ppm Mo; (b) Float sample (5233609) containing molybdenite in quartz veining (>2000 ppm Mo); (c) Float sample (5233611) containing arsenopyrite + molybdenite in a quartz vein (6.3 g/t Au, 1,273 ppm Mo, and 0.14% Pb). For scale reference, assay tags are all 9 cm tall.
Examples of Porphyry-Related Geophysical Responses
This section is intended to present case studies of chargeability and resistivity features from known porphyry deposits. Geophysical characteristics are important components of exploration, but they are not necessarily indicative of economic mineralization alone, and require additional exploration (such as drilling) to define the source of geophysical anomalies. All of the examples presented below are from public sources on deposits and properties that are not affiliated with Trailbreaker. Trailbreaker did not collect the data, prepare these figures, nor validate the data presented within. The reader is also cautioned that although these examples are from mineral deposits, there is no guarantee that similar geophysical features on Trailbreaker’s property will represent a mineral resource in compliance with standards under National Instrument 43-101.

Figure 6 displays the cross-sectional distribution of pyrite and chalcopyrite (a and b) and how these compare to the donut-shaped chargeability high (c) at the Batu Hijau porphyry copper system in Indonesia4. The chargeability best reflects the distribution of the pyrite content, with the central high feature coincident with the chalcopyrite-rich core.

Figure 7 presents the alteration zonation, magnetic response, resistivity, and chargeability features surrounding the Elang copper porphyry deposit in Indonesia1. There is a strong correlation between the high chargeability and low resistivity features where associated with the pyrophyllite-dickite-kao-alunite and sericite-illite-kaolinite alteration assemblages.

About the Swan Target
The Swan target is located on the eastern side of the Atsutla Gold project in northwestern BC. The Swan is a potential Au-Ag-Cu porphyry system, defined by a 900 m by 700 m Au-Ag-Cu-As – antimony (Sb) –Mo – lead (Pb) soil geochemical anomaly along a gossanous ridge. The host setting is a granodiorite porphyry intrusion with zoned advanced argillic and phyllic alteration assemblages. Bedrock sampling by Trailbreaker in the centre of the soil anomaly has returned values up to 11.5 g/t Au and 16.8 g/t Ag, associated with sulphide-rich veins. A near in-situ (“subcrop”) rock sample returned values of 11.7 g/t Au, 95 g/t Ag, and 0.81% Cu. The surface geochemical anomalies are associated with mapped advanced argillic alteration, which may represent the upper portion of a porphyry system.
IP surveying around the Swan target defined a donut-shaped chargeability high feature. The southern portion of this chargeability high is coincident with a resistivity low feature. The combined chargeability high and resistivity low features are interpreted to potentially represent the outer phyllic alteration zone of a porphyry system.
About the Atsulta Gold Project
The Atsutla Gold project covers over 40,000 hectares of underexplored and prospective ground in northwestern BC. The project covers a portion of the Atsutla mountain range 70 km south of the BC-Yukon border. Placer gold was recorded in the area during the early 1900s, with very little subsequent mineral exploration.
The project is centered along the crustal-scale Teslin-Thibert fault system that marks the division between the Quesnel and Cache Creek terranes. Gold mineralization is associated with Mesozoic intrusive batholiths that are the predominant geological unit on the property. Trailbreaker has discovered five significant zones of gold mineralization across the property. These are:
Swan Zone – discussed above – Au-Cu-Ag porphyry target defined by a 900 m by 700 m multi-element soil geochemical anomaly. Rock samples grading up to 11.5 g/t Au and 16.8 g/t Ag are coincident with a 2.1 km x 1.4 km donut-shaped chargeability high feature.
Highlands Zone – A 750 m by 600 m area in the western Atsutla Gold project region, with veins containing coarse visible gold and assaying up to 630 g/t Au and 1,894 g/t Ag.
Christmas Creek Zone – Gold-bearing quartz veins 2 km east of the Highlands Zone, with rock samples assaying up to 102 g/t Au and 524 g/t Ag.
Snook Zone – High-grade veins 3.5 km northeast of the Highlands Zone, with rock samples assaying up to 53.3 g/t.
Willie Jack Zone – 1.25-km long gold-in-soil anomaly with soil samples assaying up to 3.77 g/t Au and rock samples up to 9.9 g/t Au.
