Location and accuracy The Aurora Prospects are about two miles south-southeast of the tip of Aurora Spit in the SE1/4 of section 2, T. 6 S., R. 11 W., of the Seward Meridian and about 12 miles northeast of Homer, Alaska. Three tunnels have been drifted along the canyon which drains Portlock Glacier. This is location 97 of Martin and others (1915); it is accurate to one quarter of a mile.

Geologic setting

Three tunnels have been driven in fractured graywacke of the Cretaceous Valdez Group, near the contact with a 20-foot-wide porphyritic dike. Martin and others (1915) did not find any indication of mineralization within the adits, but they did find some disseminated pyrite in the dump.
