|Location and accuracy||Prospects developed by Bursik and Kern (Mertie, 1918, p. 429) are on the south and southwestern slopes of King Mountain in upper Anvil Creek and extending southeastward toward Dexter. The map location is at an elevation of 750 feet in the north-central part of section 30, T. 10 S., R. 33 W., Kateel River Meridian. The site corresponds to locality 45 of Cobb (1972 [MF 463], 1978 [OFR 78-93]), and locality 6 of Cathcart (1922, p. 238 and figure 18).|
Geologic descriptionEight claims owned by Bursik and Kern were located on the west and southwest flank of King Mountain (Mertie, 1918 [B 662-I, p. 429]; Cathcart, 1922, locality 6, figure 18). On the claims, bleached (?) marble probably contains lenses of white quartz, and iron-stained quartz and schist were reported in shallow shafts. The owners of the property reported that more than 100 assays from an 85-foot shaft ranged from 2.50 to 3.75 dollars per ton (about 0.125 to 0.175 ounce of gold per ton). Cathcart (1922, p. 238) found only a little mineralized schist and marble in a cut; no assays were made. The Anvil Creek fault transects the area nearby. This fault is a through-going, high-angle structure that juxtaposes different types of graphitic schist in this area (Hummel, 1962 [MF 247]). Bedrock at the prospect is mostly graphitic schist probably of early Paleozoic protolith age (Hummel, 1962 [MF 247]; Sainsbury, Hummel, and Hudson, 1972 [OFR 72-326]; Till and Dumoulin, 1994; Bundtzen and others, 1994).

|Workings or exploration||One 85-foot shaft (at an elevation of 700 feet), a 20-foot adit (at an elevation of 900 feet), and shallow shafts or pits were dug by Bursik and Kern before 1916 (Mertie, 1918 [B 662-I, p. 429]). More recent work has probably not been done in this area.|
