underground workings show mineralization in andesitic volcanics
in an area mainly less than 500 feet tide lying south and east
of a quartz porphyry mass that has offshoot dykes extending into
the mineralized area,

The mineralized zone consists mostly of fissure veins
bordered by completely replaced and highly mineralized rock and
somewhat altered wall-rock. In places shear ana fracture zones
are traversed by these veins and are in part extensively replaced.
There are many tiny veins; a number for short distances range
from 6 to 18 inches. Some zones of fissure veins and replaced
rock range up to 3 feet and with the altered wall-rock to
somewhat more. On the surface three main zones, Nos. 2,3, and
4, may have lengths of 800 feet, 400 feet, and 300 feet,
respectively. No. 2 deposit for 300 feet has one vein O to 18
inches, but chiefly 4 66 6 inches, wide, bordered in places by
1 foot of well-mineralized rock and 2 feet of altered wall-rock;
No. 3 for 300 feet has a fissure vein 6 to 12 inches wide and a
well-mineralized zone up to 4 feet in width. A fourth vein has
only a few inches of vein material. In underground workings
(at a depth very roughly estimated to be 100 feet) No. 3 deposit
for 100 feet beyond the southern limit of the surface showings
is made up of a vein mainly 6 to 8 inches wide, and for 20 feet
below the best surface showings is a zone 3 feet wide that is
badly split up and occurs in a dyke of quartz porphyry. What
may be No. 4 extends at least for 75 feet and contains a vein
4 to 6 inches wide and well-mineralized rock up to 18 inches.
The minerals are mainly pyrite in quartz with free gold; minor
quantities of hematite, galena, sphalerite, and carbonate are
also present. The veins assay up ve several ounces of gold to
the ton. Assays are erratic but results suggest that the vein
material and completely replaced wall-rock are probably high-grade.

It is improbable that the less altered wall-rock can be regarded as

being of value.
