Geologic setting

Geologic description The country rocks in the area of this occurrence are Lower Cretaceous to Upper Jurassic, monotonous, intensely deformed and locally highly metamorphosed turbidites. The occurrence consists of copper- and nickel-bearing sulfide minerals disseminated in the sedimentary rocks (Clark and Cobb, 1972).
Geologic map unit	(-148.863283564772, 63.4235397077144)
Mineral deposit model	Besshi massive sulfide? (Cox and Singer, 1986; model 24b?).
Mineral deposit model number	24b?
Age of mineralization	The sulfide minerals may be syngenetic with their Lower Cretaceous to Upper Jurassic sedimentary host rocks.
