The GRANODIORITE ZONE, within the Murray property, is located south of the Blackwater River in the Nechako Basin, approximately 64 kilometres northwest of Quesnel.

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 Eocene Topley intrusion granodiorite as evident by the sediments generally occurring as inclusions in the granodiorite. The sedimentary inclusions carry disseminated sulphides, pyrite and pyrrhotite. The granodiorite also intrudes northwest trending strongly serpentinized ultramafic rocks of the Paleozoic Trembleur Suite.

In 1969, Drill hole A-8, by Rio Tinto, was uniformly mineralized with chalcopyrite, molybdenite and pyrite between 29.3 and 152.4 metres (123.1 m interval) and returned 0.11 per cent copper and 0.04 per cent MoS2. The highest copper value was 0.25 per cent and the highest molybdenite value was 0.38 per cent. In 2013 a select grab sample from Pit 5 mineralized diorite returned 0.39 per cent copper and continuous chip samples over 10 metres achieved a weighted average of 0.11 per cent copper (Assessment Report 34370).

Initial recorded work in the area was performed by Rio Tinto 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.
