Location: The King prospect is in the isolated upland north of the upper King Salmon River, the highest point of which is marked by VABM King. The exact location of the prospect on the upland is unknown and is somewhat arbitrarily plotted at VABM King in the SE1/4, section 21, T. 3 N., R. 51 W. The prospect is probably within a mile of VABM King.
Geology: Cominco discovered and explored this prospect during a reconnaissance exploration program in the early 1980s (Travis Hudson, personal knowledge, 2005). The prospect is in an area of hornfels developed from the sedimentary rocks of the Cretaceous Kuskokwim Group. Felsic intrusions cut the hornfels and intense tourmaline alteration is locally developed. The prospect was originally considered to be a silver prospect. However, stream sediments and rock samples contain anomalous tin values and some contain anomalous gold values. TNR Gold Corporation (2005) was exploring this prospect in 2005 as part of their district exploration program centered on the Shotgun prospect (TA007).
Workings: Joe Piekenbrock discovered this prospect in 1981 during an initial reconnaissance of the area for Cominco Exploration. Cominco mapped and sampled the prospect in the early 1980s. TNR Gold Corporation was exploring this prospect in 2005 as part of their district exploration program centered on the Shotgun prospect (TA007).
Age: Probably Latest Cretaceous, the age of intrusive rocks and mineralization in the nearby Shotgun (TA007) prospect area.
Alteration: Silicification and tourmalinization.
Commodities (Major) - Au; (Minor) - Ag, Sn
Development Status: None
Deposit Model: Quartz veins in hornfels and felsic intrusive rocks.
