|Location and accuracy||This occurrence is located at the rim of a prominent spur in the western Candle Hills about 3 kilometers due west of Candle placer mine (MG002) at an elevation of 1,000 feet (304 m) in the NW1/4 sec. 16, T. 32 N., R. 35 W., of the Seward Meridian. The reporter investigated the site in 1978 (as ADGGS station no. 78BT364).|
Geologic descriptionThis occurrence consists of chalcopyrite blebs and disseminations in quartz-epidote veinlets hosted in a porphyritic, subaerial basalt radiometrically dated at 73 Ma (Bundtzen and Miller, 1997). The occurrence is limited to a small 5 meter by 6 meter outcrop surrounded by vegetation and talus. One grab sample contained 233 ppm copper and 0.9 grams/tonne silver (Bundtzen and Laird, 1983).

|Alteration of deposit||Epidote.|
|Workings or exploration||One grab sample contained 233 ppm copper and 0.9 grams/tonne silver (Bundtzen and Laird, 1983).|
|Indication of production||None|
Additional commentsMineralization may be related to the Au-polymetallic prospect in the valley of Candle Creek (MG003).
