The Gooseneck 3-4 occurrence is located on ridge between Upper Campbell and Gooseneck lakes, approximately 5.2 kilometres north of Wokas 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 (Area 3) of chalcopyrite-malachite fracture coatings in altered granodiorite occurs in a road cut on south side of ridge, with scattered outcrops with fracture and disseminated chalcopyrite extending southwest to the low side of a ridge adjacent to a small stream. This area of exposed surface mineralization is approximately 120 metres long by 100 metres wide. Adjacent to the showing an andesite-basalt dike, about 10 metres wide, cuts 64 degrees through altered granodiorite (Area 4). The hanging-wall(?) contains siliceous-calcareous bands hosting chalcopyrite, malachite and azurite.
In 2010, a select grab sample (JLP-10-33) of garnet-altered granite containing chalcopyrite and malachite assayed 0.0762 per cent zinc and greater than 1 per cent copper; other samples (JLP-10-36) with no description yielded up to 44.9 grams per tonne silver, 0.957 per cent zinc and greater than 1 per cent each of copper and lead (Assessment Report 31581). The sample locations were not identified.
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 1) indicated that this zone is northeast trending, approximately 200 by 350 metres in size, at depths of 20 to 120 metres below surface and open to both the south west and north east directions (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 pograms of soil geochemical surveys, geological mapping and ground induced polarization and total field magnetometer geophysical surveys on the area as the Goose Neck property.
