The Murray (Ultramafic zone) occurrence is located south of the Blackwater River, approximately 80 kilometres northwest of Quesnel.

The area is underlain by Cache Creek Group sedimentary and volcanic rock in contact with granodiorite and ultramafic intrusive.

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.

Between 2006 to 2010, a program of prospecting, geological mapping and rock geochemical sampling was completed. Previous work in the area was performed by Rio Tinto, during 1967 to 1970, and included three drill holes, totalling 469.5 metres, and various geophysical surveys. In 2006, a sample across the Ultramafic Zone returned 8.75 per cent copper (Assessment Report 28536).
