and the following information was largely obtained from Mr.
MacClellan.

The deposit consists of a vein averaging 9 feet thick, striking
north 40 degrees west and with a vertical dip. The vein is
slightly irregular, and apparently faulted off at the southeast
end. The vein material is almost wholly milky quartz, occurring
as a replacement of a brecciated zone in the Yakoun volcanics.
Irregularly distributed through the vein are bunches of sul-
phides, containing galena, sphalerite, pyrite, and chalcopyrite.
The gold occurs in the galena, which carries up to 30 ounces in
silver, and also with an unknown yellow mineral encrusting
some of the specimens in thin films. Occasionally, free gold may
be seen with the naked eye, but usually it can not be thus made
out. Specimens of galena gave assays as high as $2,600 to the
ton, but the bunchy nature of the ore necessitates thorough pros-
pecting before the value of the property can be definitely estab-
lished.

Gold is reported to occur in the flow of bostonitic trachyte
on the west side of Harrison island in Juskatla inlet. Mr.
Robertson, owner of the claim, states that free gold is sometimes
visible in the rock, and that assays from nothing to several
hundred dollars to the ton have been obtained. Pyrite is found
disseminated in very minute crystals throughout the rock, and
pyrite or marcasite form infrequent films on small joint surfaces.
It is possible that these minerals carry gold.
