about 100 feet dowm the slope to a lower adit. The wide part at
the central adit is heavily ribboned with quartz carrying much
pyrite and some chalcopyrite, and these minerals are massive as
if replacing the schist for widths of several inches. Thirty
tons of this material, hanc-sorted, yielded on an average:

gold, 1.6 ounce to the ton; silver, 1.4 ounce; and copper, 1.1
per cent. Both down and up the slope from the central adit the
ceposit becomes poorer as the zone narrows and the intensity of
the schistosity decreases.

In the upper adit a short distance from the entrance,
the shear zone is replaced by 3 feet of practically barren quartz
carrying chlorite. In the lower adit, 25 feet vertically below
the central adit, the zone is also replaced by quartz 18 inches
wide at a point 80 feet from the portal, but increasing in width
to 12 feet at the face 130 feet from the portal. The quartz
carries some pyrite in places, but at the face of the adit it is
largely barren and assay returns yield no values.

The diorite in which the shear zone lies varies from
north to south in a manner that suggests the approach to a
contact. This and the change in character of the mincralization
to barren quartz with chlorite suggest that the deposit formed
near the contact of the intrusive and carried values for only a
short distance within the intrusive body. In this case the
contact possibly corresponded roughly to the present surface but
was some distance above this plane. If so it would appear that
the best part of the deposit has been removed and only the root
left, and that at any place barren quartz will be reached in a

short vertical distance.
