Location and accuracy Slate Creek flows east-northeast to Eldorado Creek; it rises below the southwest end of Brooker Mountain in the westernmost Kantishna Hills. The creek is auriferous from near the Slate Creek antimony mine (MM153) downstream for about two miles where it enters Eldorado Creek. For this record, the site is approximately halfway from the Slate Creek mine to the confluence of Slate and Eldorado Creeks.

Geologic setting

Geologic description

Slate Creek originates at the Slate Creek (Taylor) mine (MM153), a complex antimony deposit in a quartzitic unit of the Birch Creek Schist (Thornsberry, McKee, and Salisbury, 1984, p. 144). Hawley and Associates (1978) found 3.6 ppm of gold (0.12 ounce of gold per ton) in a soil sample collected southwest of, and upstream from, the mine. The soil also contains 660 ppm of antimony (Hawley and Associates, 1978, no. 4, table 4.1-A.(1). Placer claims were located in the creek below the mine and are listed in the Alaska state Kardex file as 66-131. Nothing is known of the grade of the placer deposit.
