but from place to place in each deposit and from deposit to
deposit there is a very wide range in composition. Most of the
ceposits carry only low valucs in golc, but the gold content
ranges to as high as 1.21 ounces (on the Zona May). It is also
reported to be high on tho Nabob. Silver values are good to high
in sections of all properties, but many assays whore other metals
are high show low silver, and in places where other metals are
low silver may be high. Copper, load, and zinc, all three, any
one, or any two, may be high to very low, or absent. Tungsten
occurs in one deposit. The minerals present include chalcopyrite,
bornite, tetrahedrite, galene, pyrite, chalcocite, sphalerite,
hematite, scheelite, native silver, and probably, free gold.

The propertics include the Frisco, Mand K, M and M,
Zona May (White Bear and South Fork), Regina, Nabob, Independence,

Hidden, and Grey Copper.

Dorreen Mountain to Kitsalas Moutain

Along the northwest side of Skeena river between Dorreen
and Kitsalas mountain there is a large area of volcanics bounded
on the northwest by granitic intrusions, in part albite rich, and
in part andesine granodiorite, and cut by innumerable small masses
mainly of these two types and of rhyolite in the form of dykes and
sills. Although geological conditions appear to be favourable,
the number of mineral deposits as yet found is not very large. A
mixed sulphide gold deposit occurs on Hardserabble creck. Chalco-
pyrite-bornite-pyrite deposits with low amounts of silver and
little or no gold occur on the Canyon group associated with
rhyolite dykes. Mony other similar deposits occur in this section.
On the Phoenix group the mineralization is mainly in the form of
veins heavily loaded with pyrite, but lacking, so far as known,
important values. On the Prosperity group there is a small pocket
of very high-grade tetrahedrite mineralization. On the Helen claim

silvor-copper-zine mincralization occurs.
