The TW (North West) occurrence is located on the eastern side of a ridge at an elevation of approximately 2000 metres, 2 kilometres northeast of Railroad Pass.

Regionally, the area lies on the east flank of the Coast Plutonic Complex. Several large roof pendants of fine clastic sediments and volcanic rocks of the upper Triassic Cadwallader Group and lower to middle Jurassic Ladner Group are encompassed and intruded by large granitic intrusions. These are intruded by feldspar porphyry dikes.

Locally, a quartz-sericite schists hosts copper mineralization. The mineralization is not described but might be similar to that of the nearby Hope (MINFILE 092JNE169) occurrence, which consists of disseminated to semi-massive pyrite-sphalerite and skarn hosted magnetite-chalcopyrite zones.

Three grab samples are reported to have assayed from 0.69 to 4 per cent copper (Property File - W. Grunewald [2002-01-01]: KEG press release - Hope Creek property).

The area has been explored since the 1990’s, following the discovery of the Hope (MINFILE 092JNE169) occurrence to the southeast. In the 1990’s, Teck completed programs of geological mapping, geochemical sampling and airborne geophysical surveys on the area. The area was explored in 1997 by T. Illidge and sampled and surveyed by W. Gruenwald in 1998. In 2003, the area was staked as the Gold King property by J.T. Shearer. During 2004 through 2006, Goldking Mining Ltd. (later Wolverine Minerals Corp.) completed programs of rock and soil sampling, geological mapping and an induced polarization survey on the area.
