The MURRAY (Ultramafic zone) occurrence, part of the Liberty (former Murray) Property, is located south of the Blackwater River, approximately 65 kilometres northwest of Quesnel and 90 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 kilometres in length and 2-4 kilometres 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 described as a drusy quartz-carbonate stockwork, with some quartz being dark grey. The structure appears gossanous due to oxidation.
Locally, at the Ultramafic Zone, a 2.1 metre wide mineralized zone lies at the contact of argillite and ultramafic units; elsewhere mineralization is confined along shear zones and lenses in the ultramafic unit. The most predominant copper mineral is malachite accompanied by chalcocite. In 2006, a sample across the Ultramafic Zone returned 8.75 per cent copper (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.
In 2024 prospecting near the southwestern extent of the 2024 soil anomaly, approximately 100 metres south of the Murray showing, resulted in rock samples from old trenches assaying up to 15.62 per cent copper ( angular float grab sample of copper oxide-stained ultramafic rock) and 23.71 per cent copper (subcrop grab sample of malachite vein in carbonate altered chert). A continuous chip sample of malachite and iron-carbonate stained argillite from a trench 130 metres southeast of the Murray showing assayed 2.15 per cent copper over 3.0 metres (Assessment Report 42641).
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 (Minfile 093G 079), 2.3 kilometres northeast of the Murray showing, 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 (Minfile 093G 078), 2.8 kilometres northeast of the Murray showing. The property was renamed the Liberty Property (Assessment Report 42641).
