Geologic setting

Geologic description

Jasper (1967) reported the bedrock of the area to be quartz diorite and likewise, the float in the creek is quartz diorite. Pan concentrates in stream gravel contained up to 90 percent magnetite, 1 percent pyrite, up to 10 percent zircon, and locally up to 15 percent scheelite.
Bedrock in the vicinity is the Willow Creek Pluton, a zoned pluton: the outer part consists of hornblende quartz diorite and lesser hornblende tonalite; the core consists of hornblende-biotite granodiorite, and lesser hornblende-biotite quartz monzodiorite and biotite quartz monzonite.
Geologic map unit (-149.382216050504, 61.7894727942046)
Age of mineralization Willow Creek Pluton is Late Cretaceous.

Production and reserves

Workings or exploration Assays of pan concentrates yield up to 130 ppm Cu and up to 5 ppm Mo (Jasper, 1967).
Indication of production None
