The JEN 1 occurrence on the Murray (Liberty) property is located in the Nechako Basin, south of the Blackwater River, approximately 65 kilometres northwest of Quesnel and 87 kilometres southwest of Prince George.
The area is underlain by the Mississippian to Jurassic Cache Creek Group sedimentary and volcanic rocks in contact with granodiorite and ultramafic intrusives. Locally, sediments are intruded by the Mesozoic Topley Intrusions, consisting of a polyphase granodiorite to diorite intrusive complex that transects the property from the southwest to the north. This intrusive complex is believed to be at least 10 km in length and 2-4 km wide. Sedimentary inclusions carry disseminated sulphides, pyrite and pyrrhotite. The granodiorite also intrudes northwest trending strongly serpentinized ultramafic rocks of the Paleozoic Trembleur Suite.
Mineralization and hydrothermal alteration have been encountered as three styles on the property:
-Vein or skarn hosted high-grade copper ± molybdenum mineralization associated with ultramafic rocks. Alteration of the ultramafic rocks about the fault/vein is of iron-carbonate, talc and actinolite.
-Porphyry style chalcopyrite + molybdenite mineralization. Chlorite (propylitic) alteration of the host granodiorite is associated with chalcopyrite ± molybdenite-pyrite-pyrrhotite stringers and quartz veins containing chalcopyrite ± molybdenite-pyrite-pyrrhotite. Intermittent quartz-sericite ± clay (phyllic) alteration overprints the propylitic alteration zones. The phyllic alteration is associated with increased quartz-vein content, with individual veins measuring up 0.75 metres in core width and associated with fault zones. Late-stage molybdenite-bearing veinlets with sericitic selvages overprint other alteration and veining.
-Low-temperature (?) quartz-veining occurs in the northern portion of the property, associated with a northwest-trending, iron-carbonate altered, fault/shear structure. Veining is descried as a drusy quartz-carbonate stockwork, with some quartz being dark grey. The structure appears gossanous due to oxidation.
Locally, a vein/shear zone along the ultramafic-argillite contact, with a true width of an estimated 19 metres and a near vertical dip occurs. Alteration from the zone extends for over 50 metres into the ultramafic host. Malachite staining is extensive and represents approximately 1 per cent copper. In 1969, all seven holes drilled into the Jen 1, 2, and 3 exposures of the 900 metre long northwest-trending Ultramafic Zone intersected appreciable amounts of mineralization in the form of malachite. In 2006, one grab sample of oxidized material from the Jen 2 area assayed 1.02 per cent copper, 0.33 gram per tonne gold and 0.8 gram per tonne silver (Assessment Report 28536)
Soil sampling in 2024 defined an approximately 10 kilometre long by up to 1.8 kilometre wide arcuate copper-in-soil anomaly on the Liberty property. Combined ZTEM and IP data interpretation defined a central 1600 metre by 800 metre area, extending to greater than 700 m of depth, having a strong chargeability response. The strong chargeability zone is within a larger area of moderate chargeability in line with the historic anomaly drill-tested during the spring of 2024. This large anomaly measures 4.0 kilometres x 3.5 kilometres and is coincident with a resistive intrusive complex transecting the property from north to south, as defined by the ZTEM survey.
Highlight drill intervals from Trailbreaker's 2024 drill program north of the Jen 1 showing include:
LIB24-001 intersected: 13.5 metres of 0.12 per cent copper and 0.03 per cent molybdenum from 257.5 metres downhole; and 6.6 metres of 0.20 per cent copper and 0.07 per cent molybdenum from 300.9 metres downhole.
LIB24-003 intersected: 34.2 m of 0.18 per cent copper and 0.04 per cent molybdenum from 385.0 metres downhole, including 14.7 metres of 0.35 per cent copper and 0.09 per cent molybdenum from 404.5 metres downhole, including 5.9 metres of 0.69 per cent copper and 0.20 per cent molybdenum from 410.2 metres downhole.
LIB24-004 intersected: 6.0 metres of 0.31 per cent copper and 0.02 per cent molybdenum from 431.0 metes downhole; and 2.3 metres of 0.33 per cent copper and 0.005 per cent molybdenum from 500.0 metres downhole.
These intercepts are all porphyry style mineralization with the exception of vein/skarn related mineralization associated with ultramafic rocks over the 5.9 metre intercept from 410.2 metres downhole in drill hole LIB24-003 .
WORK HISTORY
The first documented exploration on the property occurred from 1967 to 1971, leading to Rio Tinto staking claims based on anomalous copper in stream sediment samples. Initial recorded work in the area was performed on their Pantage project, during 1967 to 1970, and included mapping, sampling, trenching, IP and magnetometer surveys. Three drill holes, totaling 477 metres, and defining the Granodiorite Zone, were completed to test an IP chargeability anomaly over granodiorite with known copper mineralization (Assessment Report 28536).
Between 1998 and 2013, W.E. Poole managed programs of prospecting, trenching, geological mapping, magnetometer and IP geophysical surveys, rock geochemical sampling and MMI soil geochemical sampling over the Murray property. These resulted in the location of a coincident 1750 by 700 metre soil-IP anomaly A (250 metres north of Rio Tinto's DDH A-8) and a 1350 by 650 metre soil anomaly B to the southwest. In 2013, a northwest trending, steeply dipping zone of epithermal quartz stockwork and breccia veining was uncovered approximately 3 kilometres to the northwest of the Porphyry Zone.
Cazador Resources Ltd. completed a 1.2 line-kilometre IP survey across anomaly A in 2015. Subsequently, B. Kreft obtained the Murray property and conducted data compilation along with rock and biogeochemical sampling in 2018 and further rock sampling in 2022.
The property was optioned to Trailbreaker Resources Ltd. in early 2024 who conducted programs of induced polarization, airborne ZTEM, soil and rock sampling and 2442 metres of diamond drilling in 7 holes. Drill locations were 200 to 350 metres northwest of the Jen 1 showings. The property was renamed the Liberty Property (Assessment Report 42641).
