Deposits carrying bornite, chalcopyrite, pyrite, and
gold constitute the most important mineral deposits so far found
on the mountain. The abumdance of copper minerais, especially
bornite, and the relative scarcity of quartz in one of the
deposits seem to distinguish these deposits from those ossociated
in origin with the albite-rich granitic rocks. |

Veins of quartz with chalcopyrite, sphalerite, pyrite,
and galena, and gold, occurring on the southwest slope of the
mountain, are similar to those found elsewhere associated with the
albite-rich intrusives. Copper deposits with low values in gold
are also present. These may be related to the rhyolite dykes.
Some mineralization similar to that noted in other localities

may be associated with the younger andesine granodiorite.

about north 75 degrees west and dips 70 degrees north. It
follows a fault and is mineralized over widths of from 1 to 6
feet, in most places 1 to 3 feet, with bornite, chalcopyrite,
pyrite, and gold. Two adits 60 feet apart vertically have been
driven along the zone, the upper for a distance of about 140 feet
and the lower for 230 feet. The zone has also been opened up
above the upper level, between the two levels, and by a winze

80 feet deep from the lower level, that is for a vertical
distance of over 150 feet and probably nearly 200 feet. Though
showing irregularities the zone is fairly well maintained
throughout and is strong at the lowest point reached. There are
minor faults on both levels, especially at the present faces.

On the lower level drifting has been carried along the fault in

the hope of picking up the mineralization to the south, but
