IOCQATON AND ACCESSIMELTTr

The Millett copper deposit is in the Iliamma Iake region, southwestern

Alaska, about 180 miles southwest of Anchorage, Alaska (fig. 1). The prospect is on the north shore of IMamna lake at Millett Point about 1-1/2 miles west of a small arm of Chekok Pay called Goose Bay; it is 12 miles east of Seversents

road hours (fig. 2).

Two other means of access to the area are available, One is by small boat

up the Kvichak Pdver and Iliamnallake from Bristol Bay; the other is by truck

across the portage from Ilama Bay on Cook Inlet to Pile Bay on Iliamna Lake, thencr :.by small boat to m latt Point. The t .crr4oze0r 4or uad: erobet

was brought Into the area over the latter route.

MIM CAL . PSWA T S AND CTII4A:

Ialamna lake, whose sueace is8 fQeefqt above sea -i8 + the lagest fresh-water lake in Alaska; it is more than 80 miles long and over R22 m1bs wide

at its widest point. Iliamna lake is drained by the Kvichak Rdver, which flows into B±stol Bay.

The topography of the project area is typical of most of the Iliamna Basin. The hills are. well-rounded as- a result of recent shet gl)~iation.. C-tly a small

amount of gls.cial til ig-- present..

Trraced parallel beaches are present at Millett Point. In trench 18, over 14 feet of clean sand 12,ing o-bculders , and gpavel was exposed.

The shores of the eastern part of Iliamna Lake are covered with a forast of

spruce, cottonwood, and birch, but only a small proportion of the spruce trees

are of-saw-log diameter. Millett Point i-s zear the souther'n andd Wwamflilimits of the forested area. Ie.re parts of the Projeot Area are coverz Only by grass

or thickets ol willows and alders, Much of the higher part of the project area is covered with mosses and lichens, which constitute the principal food of the reindeer.

In addition, two small mineralized zones are exposed on the west side of

the e. .The first, sapled in tzench I., is triangular end is. 70 feet long,

with a mefWiv eith of 35 feet. The second z6 odin trench ,is 5

feet wide by 50 feet.ong.7

The strike and dip of the lime tone in the mineralized area are not

constant; the strike ranges from N. 1760W. to N. 160 E. The average strike of

the bdeA is N. 05° W.; the dip ranges, from 55° to 809 easterly.!

The second main deposit is 1,250 feet north of the southernmst main deposit,

It is. on olaims Zamd 3of the Copper Kirng Ledge (fig. 6). This deposit, 735

feet long, aosists of two mineralized zones 500 an4d l5 feet Leng, respectively,

separated by 50 feet of unzrinerali ed black limestons. The smallerk qoutheim

mineralized zone is on the east side of a dike, whichis incised into the south

end of the main zone of mineralization. The average width of the smaL1o'

mineralized zone is 19.1 feet; its average grade is 0.98 percent copper. The

larger mineralized zone, 500 feet long, averages 29.5 feet in width; its

average copper content is o.64 percent. Five small mineralized zones are in

the same area (fig. 6).

The mineralized zones in the area covering the northernmost main deposit

are delimited by 13 trenches and 2 diamond-drill holes.

In addition, two other mineralized zones are in the area between the two

main deposits. The first zone, northwest of the southernmost deposit, is 175

feet long; it averages 8.4 feet wide, with 1.43 percent copper. Two trenches

were excavated through this deposit, The other mineralized zone is midway

between the main deposits. It is 135 feet long, contains 0.54 percent copper, and averages 1I0.4 feet wide. Two trenches and one diamond-drill hole delimit

this zone.

Idealized sections through the diamond-drill holes are shown on figures 7

through 12, inclusive.

WORK BY BUREAU CF MINES

The Bureau of Mines program of trenching, sampling, mapping, and diamonddrilling the contact deposits of copper mineralization at Millett Point was

begun August 8, 1949. During the investigation, 38 trenches were excavated by tractor-dozer and cleaned by hand trenching before channel samples were taken.

The total combined length of the trenches was 6,229 feet. From these trenches

165 channel samples averaging 1 inch by 3 inches in orass section, were taken.

As taken, the 5-foot channel samples weighed approximately 8 pounds per linear

foot. The samples were crushed and reduced to an average of 8 pounds per sample before shipment.

Two diamond-drill holes were completed and a third was at a depth of 315

feet when the project was recessed November 28 because the source of drilling

water was frozen.

Previously, a topographic and geologic map on a scale of - inch to 50 feet

had been prepared. The locations of all trenches and diamond-drill holes are

shown on this map.

Jiamamnd drilling was resumed y 28, 1950, td completeJia I'r l95O.

Six holes were drilled' duing the project; their combined leigth w*a 232.56

feet. Twenty-eight samples of core were taken for analyseS.
