Regional and property geology
The Kinsley Property is located in eastern Nevada near the Utah border, in the eastern portion of the Basin and Range physiographic province. The region is primarily underlain by carbonate and siliciclastic strata ranging from Late Proterozoic to Late Paleozoic in age, reflecting rifting and subsequent passive margin sedimentation with episodic shallowing over time. Strata were thrust- imbricated, folded and metamorphosed during the Jurassic Elko Orogeny, during which felsic to intermediate plutonic rocks were emplaced. The Tertiary is dominated by extensional tectonics, manifested as low-angle normal faulting, felsic volcanism and gold mineralization during the Early to middle Tertiary and high-angle, basin-and-range style normal faulting ranging from Miocene to Recent.
Sedimentary rocks on the Kinsley Property range primarily from Middle Cambrian to Late Ordovician in age, and reflect episodic shallowing of the continental shelf from shelf margin through middle shelf/sabkha environments. Important units include the Upper Cambrian Lamb Dolomite, Candland Shale and Notch Peak Formation, and the Lower Ordovician Pogonip Group silty limestone and Eureka Quartzite. By analogy with the Long Canyon area 75 km to the north, competent units such as the Lamb Dolomite and Eureka Quartzite might be expected to behave as structural and hydrologic buttresses for less competent and more favourable host rocks such as the Candland Shale and lower Pogonip Group. The Candland Shale is the principal host for gold mineralization discovered to date on the Kinsley Property.
Strata in the Kinsley Mountain area were ductily deformed during Mesozoic time, the extent to which has not been thoroughly evaluated. During the Eocene, a northwest-trending wrench fault system was developed across the property. This fault system provided the plumbing which introduced mineralizing fluids into the Candland Shale. Mineralization is sediment-hosted in nature, and is believed to be of similar age (approximately 38 Ma) to mineralization in the Carlin Trend. Detailed mapping in the pits suggests that mineralization may also be controlled by north- to northeast-striking structures, which may extend known gold mineralization to the north an unknown distance. This possibility is being tested with the 2013 drilling program.
Surface and near-surface alteration includes decalcification and iron oxide alteration (primarily limonite, goethite and rare hematite). Some scorodite is present locally, as well as structurally and stratigraphically controlled jasperoids lenses. At depths below approximately 70 metres, sulphide mineralization is locally present, consisting of variably siliceous, decalcified and carbonaceous rock with disseminated, very fine-grained pyrite and arsenical pyrite. All of the above alteration types contain gold as very fined-grained particles in the lattice of arsenical pyrite grains or oxidized equivalents. Highly geochemically anomalous, structurally controlled jasperoid bodies have been mapped and sampled up to 7 km north of the existing pits.
In September 2013, Liberty Gold obtained a key permit for Kinsley Mountain allowing the Company to ramp up drilling to test high-priority targets across the core group of claims. The approved Plan of Operations allows Liberty Gold up to 70 acres for exploration and development drilling on the core group of claims, including the Western Flank, Candland Canyon and extensions trending NNE and SW of the historic pits.
