by Lower Tertiary andesitic and dacitic lava flows and breccias. The Tertiary rocks are intruded or overlain 

by minor basaltic plugs, dikes, and flows (Riehle and others, 1993). Activity at this occurrence seems to be 

limited to claim staking and minor exploration. Several blocks of claims, denoted as Nos. 1 and 2 were filed 

in 1978-1984.

 The country rocks along Gorge Creek near this reported placer cinnabar occurrence are the Northeast 

Creek Sandstone Member of the Upper Jurassic Naknek Formation (Riehle and others, 1993). This occurrence could not be found during the U.S. Geological Survey AMRAP study of the Mount Katmai quadrangle during the 1980's although the sampling density was low and sampling was difficult because of the steep 

topography (Church and others, 1992; Riehle and others, 1993). No cinnabar was identified in the heavy 

mineral concentrates from streams in this area. There were claims staked in this area for placer cinnabar 

(Roehm, 1941).

 This occurrence consists of small, galena-bearing quartz veins in a Tertiary hypabyssal stock. Nearby, 

float consists of large fragments of quartz with sphalerite and galena in vugs. The quartz veins probably 

also contain pyrite and chalcopyrite. The lack of abrasion on the galena crystals and the size of the fragments of float suggests their source is near the quartz veins (Church, Riehle, and Goldfarb, 1993). 

Alteration:

 Nearby stocks show pervasive propylitic alteration at their margins. 

Age of mineralization:

 Tertiary or younger; the small galena-bearing quartz veins cut a Tertiary hypabyssal pluton. 

Deposit model:

Polymetallic vein (Cox and Singer, 1986; model 22c). 

Deposit model number (After Cox and Singer, 1986 or Bliss, 1992):

22c

 Other: Ag, As, Mo, Zn 

Ore minerals: Gold, jordisite, pyrite 

Gangue minerals: Quartz, smectite-illite, stilbite 

Geologic description:

 This occurrence is in Upper Tertiary, propylitically-altered, volcanic rocks, that contain banded quartz 

veins, generally one to five mm thick and finely disseminated pyrite (Church, Riehle, and Goldfarb, 1993). 

The veins contain quartz, smectite-illite mixed-layer clay, and stilbite. Samples generally contain from 0.15 

to 0.45 parts per million (ppm) gold with a maximum value of 2.2 ppm, and up to to 300 ppm arsenic, 200 

ppm molybdenum, and 3 ppm silver. The dark color of the quartz bands is due to finely dispersed jordisite 

(MoS2) (Church, Riehle, and Goldfarb, 1993). The occurrence may represent veining above a concealed 

low-F porphyry Mo deposit (Church, Riehle, and Goldfarb, 1993).

Geologic description:

 This occurrence is in hydrothermally altered, Upper Tertiary volcanic rocks, and consists of quartz veins 

with finely disseminated pyrite. The volcanic rocks are moderately to intensely altered to propylitic, argillic, phyllic, and potassic mineral assemblages. Church, Riehle, and Goldfarb (1993) collected samples along 

a traverse about a mile long. The samples contained up to 5 parts per million (ppm) gold, but most values 

are about 200 parts per billion. They also contain up to 10 ppm molybdenum, 0.5 ppm silver, 800 ppm arsenic, and 100 ppm zinc. The occurrence might reflect a concealed low-F, porphyry Mo type deposit. The occurrence is one of several similar sites along a northwest-striking, regional shear zone (Church, Riehle, and
