Location: USBM OF 75-92 location KR64. Located on an unnamed northwestern tributary near the headwaters of the Kurupa River. Known to within one mile.
Geology: Outcrops of sandstone and siltstone of the Kanayut Conglomerate are cut by sulfide-bearing anastomosing quartz veins that trend north-south and are exposed for 60 meters along strike. Chalcopyrite was the only sulfide identified, and it occurs with associated malachite and azurite stain.
Workings: Samples of quartz-bearing veins contain up to 0.56% Cu.
