Porcupine Creek

M. F. Burke, of Cedarvale, and F. McLean and J. Bulzac of Prince
Rupert, did considerable work in 1936 on their placer lease 3 miles above the
mouth of Porcupine creek. About 1,000 feet downstream from the shear
zone on the Windfall group an adit was driven south into the south bank of
Porcupine creek a few feet above water-level. The adit is about 75 feet
in length and follows closely the contact between bedrock and overlying
gravels. As the banks of Porcupine creek are comprised of steep blufis
of argillite and tuff about 40 feet in height elsewhere in this vicinity, there
is some evidence that the adit follows an old abandoned stream channel.
Some fairly coarse gold was recovered during the summer by sluicing the
gravels taken from the adit. The owners estimate the gravel to carry about
10 cents a yard in gold.

During sluicing operations considerable coarse pyrite was found to
collect in the riffle-boxes. A sample of this pyrite gave on assay: gold,
1:14 ounces a ton; silver, 0-80 ounce a ton.

Kleanza Creek

Cassiar Hydraulic Mining Company installed a complete hydraulic
plant on Kleanza creek in 1912 and carried on intermittent operations
until 1922. There is no record of the amount of gold recovered by this
company, but it is reported that much time and money were lost in re-
placing equipment washed away during spring and autumn floods. In
recent years several persons have been engaged in small-scale sluicing
operations about 2 miles above the mouth of the creek, and small amounts
of placer gold are recovered yearly. The gold has apparently been con-
centrated since glacial times by the reworking of the creek gravels and
glacial debris as creek deepening progressed. Diouglas Lay (1932) believes
that a pre-glacial channel segment lies buried beneath a moraine on the
north side of the canyon 14 miles above the mouth of the creek. He states
that the rims of the ancient channel are exposed below the downstream
end of the canyon.

MARL DEPOSITS}
Buccaneer of the North Claim (38)
References: Ann. Repts., Minister of Mines, B.C.: 1931, p. 72; 1932, p. 90.

The Buccaneer of the North claim, owned by August Johnson, is 1
mile west by truck road from Ritchie flag station. Several carloads of
marl were shipped last summer from this claim to be used as a land
dressing by farmers at Terrace.

A mar! deposit 300 feet wide, 350 feet long, and of undetermined depth
occurs on the gently dipping eastern shore-line of a small lake. The lake
