Site type: Prospect 

ARDF no.: BS002 

Latitude: 59.895 Quadrangle: BS D-7 

Longitude: 149.281 

Location description and accuracy:

 The occurrence is located on the Resurrection Peninsula about 1.7 miles north of Cape 

Resurrection on the southwest flank of Hill 2077. The main showing is about three quarters of a mile east of the shore along a cliff in the NE1/4 of section 28, T. 3 S., R. 1 E., of 

the Seward Meridian. At the base of the cliff, there is a 8 to 10 feet thick breccia zone 

that strikes N78E and dips vertically. Higher up and about 300 feet to the east another 

similar zone (possibly the same one faulted a little to the north) is 8 to 10 feet thick. 

This is location 6 of Cobb and Tysdal (1980) and location 109 in Tysdal (1978). This location is accurate within a quarter of a mile. 

Commodities: 

 Main: Cu 

 Other: 

Ore minerals: Chalcopyrite, marcasite, pyrite 

Gangue minerals: Quartz 

Geologic description:

 Tysdal and Case (1979) described the bedrock geology in this area as Cretaceous, pale 

to dark green, aphanitic to porphyritic pillow basalt with subordinate pillow breccia, tuff, 

and siltstone. 

 The mineralization is hosted in a breccia that is fractured and recemented with quartz 

and sulfides, The breccia cement is soft and weathers to a gossen, although the sulfides 

are not evenly distributed through the cement. One zone 6 foot wide is particularly rich 

in sulfides. A sample of this material assayed 9.8% copper (Martin and others, 1915). 

Alteration:

Cement in breccia is iron stained and weathered to gossen. 

Age of mineralization:

Cretaceous.

ARDF no.: BS007 

Latitude: 59.907 Quadrangle: BS D-7 

Longitude: 149.289 

Location description and accuracy:

 The prospect is on the east shore of Resurrection Bay, opposite Renard Island (Fox Island) in the NW1/4 of section 21, T. 3 S., R. 1 E., of the Seward Meridian. A small adit 

has been driven above the high tide level in a brecciated metamorphosed basalt. The 

breccia as exposed is 12 feet thick and has been traced 100 feet or more along the shore. 

This is prospect number 78 of Martin and others (1915, p. 235) and location 108 of Tysdal (1978). This location is accurate to within a quarter of a mile. 

Commodities: 

 Main: Cu, Zn 

 Other: 

Ore minerals: Chalcopyrite, pyrite, sphalerite 

Gangue minerals: Calcite, quartz 

Geologic description:

 The host rock is a Lower Cretaceous diabase (Tysdal and Case, 1979) that has been 

brecciated and recemented by quartz and sulfide mineralization. The breccia is composed of fine-grained, diabase fragments which range in size from less than a fourth of an 

inch to several inches in size. The matrix material is a greenish cement. The original 

breccia is probably a flow breccia mixed with tuffaceous material that has been slightly 

broken and rehealed with quartz, and pyrite with a little calcite and chalcopyrite (Martin 

and others, 1915). The breccia is about 12 feet wide at this location and an sample across 

this zone showed 1.1% copper (Grant and Higgins, 1909, p. 104-105). 

Alteration:

Silicification.

Geologic description:

 Martin and others, (1915) examined hand samples from this occurrence and described 

them as quartz containing fragments of diabase, pyrite, and a little chalcopyrite. They 

then went on to speculate that this occurrence is similar to the Fairview and Iron Mask 

prospects (Martin and others, 1915). Tysdal and Case (1979) described the bedrock geology in this area as Cretaceous, pale to dark green aphyric to porphyritic pillow basalts 

with subordinate pillow breccia, tuff, and siltstones. Along the west shore of Resurrection Bay the pillows are right side up, dip 30 to 50W, and the long axes of the pillows 

and pillow bifurcation plung westward down dip.

ARDF no.: BS013 

Latitude: 59.965 Quadrangle: BS D-3 

Longitude: 147.989 

Location description and accuracy:

 The occurrence consists of three tunnels that are located just below VABM Fairview 

1926; it is in the NE1/4 of section 36, T. 2 S., R. 8 E., of the Seward Meridian. The lower 

tunnel is at an elevation of 1,150 feet . The middle tunnel is at an elevation of 1,350 feet 

and the upper tunnel is at an elevation of 1,450 feet. There is an open cut on the discovery outcrop just above the upper tunnel . This is location number 8 of Cobb (1972, MF440) and location 270 of Tysdal (1978). This location is accurate to within a quarter of a 

mile. 

Commodities: 

 Main: Cu, Zn 

 Other: Ag 

Ore minerals: Chalcopyrite, pyrrhotite, sphalerite 

Gangue minerals: Quartz 

Geologic description:

 The country rock in the vicinity of the prospect is graywacke and shale of the Tertiary 

Orca Group (Nelson and others, 1980). The strike of the bedding is northeast and dips 

70W. The mineralization consists of siliceous massive sulfides and stringers of sulfides 

containing predominantly pyrite, pyrrhotite, and chalcopyrite. The mineralization varies 

from 18 to 66 inches in width and strikes N35 to 50E and dips 70 to 80W. Locally the 

mineralization is parallel to the schistosity of the country rock. Samples by the Bureau of 

Mines (Kurtak and Jeske, 1986) assayed up to 6.5% copper and 14 ppm silver. 

Alteration:

None reported. 

Age of mineralization:

Tertiary; massive sulfides in Tertiary rocks.

Workings/exploration:

 There were 840 feet of underground workings driven between 1908 and 1911. In 1911 a 

mill was set up and run for a short while. In 1914 a test shipment of 12 tons of ore that 

ran 0.97% copper and 1.92 ounces of silver per ton resulted in the production of 2,350 

pounds of copper and 23 ounces of silver (Johnson, 1918 p. 209-210). The prospect has 

tunnels at three levels and one open cut. The lower two tunnels are the most extensively 

developed. The lower tunnel is collapsed and reported to consists of 400 feet of workings . The middle tunnel was open in 1985 and is about 400 feet long; two drifts, 20 feet 

and 50 feet in length, were driven along the mineralized zone. The Bureau of Mines 

(Kurtak and Jeske, 1986) sampled the middle tunnel across a four foot width that contained 6.5% copper and 14 ppm silver. The 40-foot-long upper tunnel is collapsed. Martin and others (1915) reported that this tunnel was weakly mineralized. In 1976, Noranda 

Exploration staked the area and conducted geophysical studies. 

Production notes:

 In 1914 a test shipment of 12 tons of ore that ran 0.97% copper and 1.92 ounces of silver per ton resulted in the production of 2,350 pounds of copper and 23 ounces of silver 

(Johnson, 1918 p. 209-210). 

Reserves:

 Kurtak and Jeske (1986) inferred a reserve of 2,900 tons copper in ore that contains 3% 

copper and 8.7ppm silver.

Location description and accuracy:

 The occurrence is located on the beach about 3/4 mile north of Cape Resurrection in 

section 33, T. 3 S., R. 1 E., of the Seward Meridian. This is location 110 of Tysdal 

(1978) and is accurate to within one quarter of a mile.

Ore minerals: Chalcopyrite, galena, pyrite, unknown zinc mineral 

Gangue minerals: Quartz 

Geologic description:

 The host rock is Upper Cretaceous sheeted basalt of the Valdez Group that has been 

sheared and brecciated (Tysdal, 1978). The shear and breccia zone is 0.6 meters wide and 

contains quartz, pyrite, chalcopyrite, and galena. Analysis showed 3 ppm silver, 70 ppm 

cadmium, 1,500 ppm copper, 3,000 ppm lead, and 9,200 ppm zinc. Tysdal (1978) considers this occurrence to be a volcanogenic massive sulfide deposit. 

Alteration:

None reported. 

Age of mineralization:

Cretaceous or younger; breccia zone in Cretaceous basalt.
