The North Minerals Star claims are located on the south-facing slopes of Keithley Creek Mountain, approximately 50 kilometres northwest of the community of Likely. Access is from Quesnel via a system of 4-wheel drive logging roads.
The area is underlain by graphitic schists and phyllites of the Upper Proterozoic Snowshoe Group and serpentinites of the Upper Paleozoic Crooked Amphibolite. Serpentine jade and nephrite jade were observed in differing locales along the north-central portion of the claims. The north branch of the headwaters of Porter Creek exposed a number of serpentine-talc shears. The general structure and fabric of the bedrock trends northwesterly and in places is intensely folded and faulted. Foliation and lineation both strike northwest and, where observed, are occasionally offset by small, crosscutting faults.
Sampling and testing of samples routinely exhibit a hardness of +6.0 and have been confirmed as nephrite jade by a number of gemologists (Assessment Report 28819). The serpentinite is black to dark green and highly sheared containing massive to foliated serpentine, sometimes with associated asbestos seams. Near the surface, nephrite jade has been recovered. The jade is an emerald green to dark green to black colour, translucent, and is fracture free and mottled. The serpentinite and serpentine is also being investiaged for its potential as a dimension stone and industrial mineral, respectively.
