The Raven occurrence is located approximately 295 kilometres northwest of Prince George, British Columbia, on the eastern edge of the Omineca Mountains, as part of the Pinchi.

The property is underlain by segments of carbonate and ultramafic rocks of the Cache Creek Group to the west, and the Jurassic Hogem Intrusive Complex, including the western margin of the Lower Jurassic Duckling Creek Syenite Complex to the east. The property is bisected by the northwest trending Pinchi Fault.

The larger-scale Pinchi Property (see MINFILE 093N 065, 093N 248, and 093N 171) has seen a limited history of exploration in several areas of the property. In the fall of 2014, geologists visited the northeast portion of the property, focussing mapping and geochemical sampling efforts in the previously noted ‘northeast magnetic target’ and ‘southeast magnetic target’ (Assessment Report 35180).

The Raven showing was discovered near the centre of the ‘northeast magnetic target’. Mineralization was found in outcrop and subcrop along a contact between a pyroxenite dike and a coarse-grained syenite. Bornite is noted as fine-grained disseminations and stringers, locally associated with magnetite. Malachite is also present as fracture coatings. Nearby, chalcopyrite occurs in pyroxenite dikes along with fracture-coating malachite. Chalcopyrite veins and stringers also occur adjacent to northeast trending structures.

At the Raven showing, rock samples returned up to 1.956 per cent copper, 335 parts per billion gold, and 16.7 parts per million silver (sample 1388 at field station AG 311, Assessment Report 35180). Nearby, rock samples returned 5301 parts per million copper (sample 3551 at field station AG 312), and 4764 parts per million copper (sample 1387 at field station AG 310). Approximately 250 metres southwest of the Raven showing, rock sample 3552 returned 6274 parts per million copper. Coincident soil and silt geochemical anomalies occur downslope of the Raven showing, covering an area 2.5 by 1.5 kilometres in size.

During 2005 through 2007, Lysander Minerals Corp. completed programs of silt and rock sampling, geological mapping and an airborne electromagnetic/resistivity survey on the area as apart of the Pinchi project.

In 2012, Tajiri Resource Corp. conducted a helicopter supported property-wide reconnaissance geochemical investigation of their OGK property. A total of 68 rock, 112 stream sediment and 383 soil samples were collected and submitted for assay. A helicopter supported airborne geophysical survey consisting of magnetics, VLF/EM and radiometric surveys over four blocks totalling 505 line-kilometres was also completed.
