The strong chargeability anomaly has not been drill-tested. However, previous diamond drilling by Trailbreaker along the margin of the moderate chargeability anomaly returned long continuous intervals of Cu-Mo porphyry-style mineralization, including 213.7 m of 0.16% CuEq in hole LIB24-001.
ZTEM resistivity and magnetic data define two additional porphyry targets, based on mottled magnetic signatures including a central magnetic high, within the resistive intrusive complex. All three porphyry targets (P1, P2, and P3) occur up-ice' of glacially transported Cu-Mo-Ag (silver) Au (gold) multi-element geochemical soil anomalies defined from 2024 soil sampling (see news release from September 16, 2024).

Discussion of results
ZTEM surveying defined a 2 to 3 km wide intrusive complex, indicated by high resistivity values (>600 Ohm-m), that transect north-south across the property, bending southwest in southern areas (Figure 3). The intrusive complex extends for at least 12 km, and resistivity modelling suggests it extends to greater than 2 km of depth.
The intrusive complex is associated with known porphyry-style mineralization encountered in the 2024 drilling (e.g. 213.7 m of 0.16% CuEq from 248.3 m to the end of hole in LIB24-001), which is associated with a moderate IP chargeability response (7-13 mV/V) and a mottled magnetic low feature flanking a magnetic high.

Historic IP surveying covered approximately 120 hectares (ha) of prospective geology along the intrusive complex boundary. The expanded IP surveying completed in 2024 includes 32.8 line-km across 11 IP sections, covering an area of approximately 1,600 ha or >13 times greater than the area previously surveyed.
The expanded survey results indicate that the mineralization encountered in the 2024 drilling may extend 4 km in a north-south orientation and 3.5 km in a northwest-southeast orientation, and extends to depths of >700 m (Figure 4). The large area of weak chargeability response displays increasing chargeability strength toward the core area and at depth, with a central core of strong chargeability (>20 mV/V) measuring 1,600 m in length, 800 m in width, and extending to >700 m of depth. The strong chargeability response may reflect increased sulphide abundance within the large hydrothermal system.
The zone of high chargeability occurs beneath a layer of glacial till and is not exposed at surface. When accounting for glacial dispersion through ice-flow indicator measurements, it is apparent that the strong geochemical anomaly, the focus of past exploration efforts, occurs 1.0 2.0 km down-ice' from this zone. Thus, the geochemical anomaly is likely sourced from this chargeability anomaly and has been glacially dispersed to its present location.

The large zone of moderate chargeability within the intrusive complex is strongly correlated with a mottled magnetic response, where magnetic high pimples' are surrounded by halos of low to moderate magnetic responses (Figure 3). The magnetic highs may reflect magnetite-bearing potassic alteration. The lows are interpreted to be caused by magnetite-destructive clay-sericite alteration, which may also have introduced sulphides into the system, causing the chargeability response.
Beyond the area covered by the IP survey, there are two other zones that display the same mottled magnetic features within the resistive intrusive complex. Both of these zones cover a similar porphyry-scale area and occur up-ice' of other coincident multi-element soil geochemical anomalies. This indicates potential for at least three multi kilometre-scale porphyry zones within the Liberty property. These newly identified zones are strong candidates for additional IP surveying to define the chargeability responses within.

Z-Axis Tipper Electromagnetic (ZTEM) Survey Parameters
Trailbreaker contracted Geotech Ltd. (Geotech) to complete an airborne Z-axis Tipper electromagnetic (ZTEM) and caesium magnetometer survey over the entire Liberty property. The survey effectively defines the resistivity and magnetic susceptibility features across the property, which is centered on the Mesozoic intrusive complex hosting known porphyry and skarn-style mineralization.
A total of 602 line-kilometers of geophysical data were acquired during the survey, covering an area of 110 km2 with 200-metre spaced east-west survey lines and 2,000-metre spaced north-south tie-lines.
Induced Polarization Survey Parameters
Trailbreaker contracted Simcoe Geoscience Ltd. (Simcoe) to complete an induced polarization survey at the Liberty property, using Simcoe's Alpha IP technology. The IP survey was designed to extend a historic (2011) IP survey that defined a weak to moderate chargeability high feature associated with Cu-Mo porphyry mineralization, and included surveying at a larger scale to cover the Cu-in-soil anomaly defined during 2024 fieldwork.
A total of 32.8 line-kilometers were surveyed along 11 IP lines, with 200 m to 400 m line spacings, and from 2.1 km to 3.8 km in length. The survey used an inline dipole-pole-dipole (reverse and forward 2D survey) array with a 100-metre dipole spacing. To increase depth of penetration, extra current injections were made at both ends of the profiles. The estimated depth of investigation of the survey is from 500 m to 700+ m, depending on the profile length.
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, which is coincident with a kilometer-scale moderate to strong chargeability anomaly and an intrusive complex with a high resistivity signature. 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. This high-grade copper mineralization is interpreted to be genetically related to a large Cu-Mo porphyry system.

* Reported widths are drill widths. Insufficient geological information exists at this point to define true widths. 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.
