The Spring occurrence is located about 70 kilometres east of the community of Dease Lake, on the western flank of the mountain west of Letain Lake.
The showing occurs within upper Mississippian to Permian Cache Creek Complex ultramafic rocks consisting of serpentinized peridotite, dunite and pyroxenite. Mafic volcanics of the Nakina Formation are the same age and also part of the Cache Creek Complex and are in contact with the ultramafic rocks forming the top of the mountain just above the showing area. The showings consist of two malachite-stained areas a few hundred metres apart.
The King Kong showings (104I 067) have been prospected intermittently between 1973 to 1985. Nephro-Jade Canada first examined the property in 1973 as the King Kong claims. Cry Lake Jade Mines Ltd. owned the property as the Spring claims and conducted a geological survey in 1979 and a magnetic survey in 1980. Mohawk Oil worked the Spring claims from 1981 to 1985, conducting geochemical, geological and geophysical surveys (induced polarization). In 1984, Mohawk Oil completed geological mapping, rock sampling, and a 31.2 line kilometre induced polarization (IP) survey over their "Spring" claims. In total, 35 rock grab, 8 float, and 2 chip samples were collected and several samples taken along the central ridge assayed anomalous copper and silver values. The IP survey resulted in four main anomalies, interpreted to be related to mineralized contacts based on high chargeability and low resistivity along portions of the ridge. The main IP anomaly was located over the King Kong showing with a northwest trend, length of 1.6 kilometres, and was correlated with lithological contacts and mineralization.
During July and August of 2007, Turnagain River Exploration Ltd. conducted a reconnaissance exploration program over the Turnagain property, consisting of prospecting and heavy mineral concentrate stream sediment sampling over at least seven showings (King Kong, 104I 067; Spring, 104I 110; King Mountain, 104I 108; PR8, 104I 109; PR7, 104I 107; Alice Shea Jade, 104I 104; and Alice Shea Creek, 104I 005).
