The Gooseneck 5 occurrence is located approximately 600 metres west of the upper end of Gooseneck Lake.

The area is underlain primarily by medium-grained crystalline granodiorite of the Jurassic Island Plutonic Suite. Other phases of the intrusive include diorite, monzonite and granite.

Locally, a zone of argillic alteration, greater than 10 metre wide and striking 64 degrees northwest, hosts pyrite and minor disseminated chalcopyrite mineralization, as exposed in a borrow pit. No samples of the zone have been reported.

In 2011 and 2012, soil surveys identified a geochemical anomaly on the area and extending to the east and south east where outcrop is rare (Assessment Report 33616). In 2013, combined chargeability-resistivity highs (Anomaly 2) indicated that this zone was northwest trending, approximately 300 by 400 metres in size, at depths of 20 to 120 metres below the surface and open to the south east (Assessment Report 33962).

In 2010, Twin Lake Resources completed a prospecting program on the area as the Mid-Island Copper property. During 2011 through 2013, Western GateWay Minerals completed programs of soil geochemical surveys, geological mapping and ground induced polarization and total field magnetometer geophysical surveys on the area as the Goose Neck property. The soil surveys identified a geochemical anomaly on the area and extending to the east and south east where outcrop is rare (Assessment Report 33616). The geophysical surveys identified two anomalies which coincided with previously identified soil anomalies and surface mineralization (Assessment Report 33962).
