iron oxide and composed of orthoclase and albite but no quartz.
The gold occurred as wires and thin leaves encircling and cut-
ting the grains of feldspar. Other nuggets largely gold have
feldspar attached to them. The fineness of this gold is 741.
The feldspar is moderately coarsely crystalline and no quartz
was seen in any of the nuggets examined.

One fact is, that not only does the gold from Alice Shea
Creek look different from that from leases Nos. 345 and 402 on
Wheaton Creek but a real difference between them is shown by
their fineness.

The black sand concentrate recovered from the sluice-
boxes consists of magnetite, small grains of a natural nickel-
iron alloy (awaruite), pyrite, hematite, chromite, as well as
native copper nuggets several inches across. No platinum is
reported and none was observed in the heavy concentrate.

The awaruite grains from the placer concentrates are as
much as 3 millimeters long. Under the microscope most of them
are rounded and worn, but some show crystal faces. The miner-
al is malleable, sectile, and magnetic. The grains have a
light bronze colour but the mineral on a cut or polished sur-
face is grey. The colour of awaruite will serve to distinguish
it from platinum, some of which may be magnetic. A sample of
awaruite picked from a magnetic concentrate made from the
black sand assayed: Nickel 72 per cent., iron 25 per cent.,
cobalt 4 per cent. and copper 1.1 per cent. A similar alloy
has been recovered from auriferous gravel on the Fraser River
2tales: trom Eillooet, B.'C., Bridge Raver, Bey C., Hoole Can-
yon on the Pelly River, Y. T., Awarua Bay, New Zealand, and
Josephine County, Oregon.

Several samples of serpentine, taken from the belt out-
cropping along Wheaton Creek, were crushed and panned. The
black sand concentrate from them contains magnetite, pyrite,
pyrrhotite, chromite, and grains of awaruite. This mineral
was also recognized in microscopic examinations of polished
surfaces of serpentine. It is evident, therefore, that the
awaruite occurs in the serpentine and that the awaruite in
the gravel has been concentrated by the erosion of serpentine.

Gold value of gravel. There is little precise informa-
tion regarding the gold value of the gravel. V. Shea, how-
ever, reports that on lease No. 355 he recovers about three-
quarters of an ounce of gold per lineal foot of creek-bed.

On lease No-~ 345 on Wheaton Creek the values are higher.
During the autumn of 1938 it is reported that about $12,000.00
in gold was recovered from a small patch of shallow gravel
