cified into a green, siliceous, banded rock containing occasional small gar-
nets. The altered rock is cut by a number of parallel, vertical faults strik-
ing north. One of these in the bed of the creek is marked by a brecciated
zone 2 to 6 feet wide cemented by calcite. It is exposed for several hundred
feet up the steep, sloping stream bed. A 24-inch channel sample taken
across the brecciated zone in the creek bed assayed: gold, 0-06 ounce a ton;
silver, 0-04 ounce a ton. f

Thirty feet west of the creek bottom an adit was driven 26 feet west
into the side of the gulch. At the face of the adit a 10-inch quartz vein
sparsely mineralized with chalcopyrite occurs along a fault striking north.
A channel sample across the vein assayed: gold, none; silver, none; copper,
0-04 per cent.

The Lucky Jim copper claims are on the main trail on the north side of
Kleanza creek, about 12 miles southeast of Usk. These claims have been
prospected from time to time since the initial discovery of copper on them in
1908. The early work was done by the present owner, Fred Forrest of
Usk. In 1924 the Federal Mining and Smelting Company drove a short
adit and in 1929 the Consolidated Mining and Smelting Company con-
tinued this work and drove a second adit. Work stopped on failure to find
substantial ore-bodies.

On the Lucky Jim claim a 7- by 7-foot inclined shaft, 20 feet deep,
was sunk beside the Kleanza Creek trail about 200 feet west of the Fred
Forrest cabin (elevation 1,650 feet). The shaft is on a fault along a contact
between two flows, which strike south 60 degrees west and dip 55 degrees
northwest. The hanging-wall is fine-grained, grey andesite, and the foot-
wall is a pink, fine-grained, chilled andesite. The rock on both sides of the
fault is altered and brecciated over a width of several inches and contains
small veinlets of chalcocite. A 12-inch channel sample taken across this
mineralized zone at the bottom of the inclined shaft assayed: gold, a trace;
silver, 0-12 ounce a ton; copper, 0:28 per cent.

On the Idaho claim, about 1,000 feet farther northwest, two adits were
driven to explore a mineralized fault zone in porphyritic andesite. The
fault outcrops for about 50 feet up and down a steep rock slope immediately
above the upper adit, which was driven for 90 feet to explore it at elevation
2,100 feet. Within the adit the fault strikes north and dips 75 degrees west.
For the most part it is marked by 4 to 6 inches of gouge mineralized with
bornite and chalcocite. Fractures and joint planes in the wall-rock are
stained with epidote and traversed by small veinlets of bornite. A channel
sample taken across the face of the adit to include 6 inches of fault gouge
and 18 inches of mineralized wall-rock assayed: gold, a trace; silver, 1-04
ounces a ton; copper, 3:76 per cent. Near the entrance to the adit a more
plentifully mineralized vein section has formed where the fault splits and
spreads. Ten feet above the adit the section enclosed by the two arms of
the fault is 4 feet wide and the brecciated andesite is replaced by innumer-
