|Location and accuracy||This prospect is in the upper valley of an unnamed south tributary to the lower Lowe River. The mouth of this tributary is 3.3 miles upstream from Canyon Slough. This prospect is on this creek in the NW1/4 section 15, T. 10 S., R. 5 W., of the Copper River Meridian. This prospect is probably located to within one-half mile. It is locality 33B of Winkler and others (1981 [OFR 80-892-B]).|
Geologic descriptionStratiform lenses and disseminations of sulfide minerals occur in mafic metavolcanic rocks and metasedimentary rocks of the Valdez Group; sulfide minerals include chalcopyrite, pyrite, pyrrhotite, and sphalerite (Winkler and others, 1981 [OFR 80-892-B]). The metavolcanic rocks probably represent ocean floor basalts that were accreted with the enclosing flysch of the Valdez Group (Winkler and others, 1981 [OFR 80-892-A].
|Geologic map unit||(-146.099312717384, 61.0020812412624)|
|Mineral deposit model||Cyprus massive sulfide (Cox and Singer, 1986; model 24a)|
