The replacement body in the main adit has been followed by drifts for
300 feet. The width varies from a few inches to 9 feet. It has been
followed up the dip for a distance of 280 feet (September, 1934) on an
average dip of 42 degrees. The body is not a single deposit, but is really
several lenticular bodies separated by thin bands of argillaceous rock. The
limestone beds in which the ore occurs split to the southeast into thinner
bands separated by argillite and finger out. The ore also acts in the same
way and the bodies end to the southeast by splitting into tapering wedges.
This limestone bed occurs in the Mid Lake adit also.

In the Mid Lake adit another calcareous bed 350 feet southwest of the
main limestone bed has been partly replaced by pyrite. This bed lies in
approximately the same stratigraphic position as the one second from the
bottom of the four cut in the main adit.

The grade of the replacement ore so far developed is roughly twice as
high as the grade of the better veins and should average about one ounce
of gold a ton.

increased to 100 tons a day. The gold is extracted by cyanide. In 1933
the mine produced 7,660 ounces of gold from 19,869 tons of ore.

Several adits have been driven west into Cow mountain from Lowhee
creek at the upper camp, but the main underground workings are adits
driven southeast into the mountain from the main camp at the foot of Jack
of Clubs lake. Underground work on the levels exceeds 4 miles. The
lowest adit from the main camp is the 1,500. The 1,200 adit is 315 feet
higher and directly over the 1,500 adit. Between the two adits are the

The 1,600 level is 105 feet below the 1,500 level and is connected to it by

The 1,500 level furnishes a good cross-section of the rocks. This level
crosses from the Baker member or near it through the Rainbow member
into the B.C. member. The rocks strike northwest and dip about 45
degrees northeast. The Rainbow member is 750 feet wide on the level
and in part of the level can be subdivided into four divisions. The lowest,
2a of Figure 8, is 150 to 300 feet wide and consists of fissile and non-fissile
grey quartzites. This division widens from northwest to southeast. The
upper part of No. 2 of Figure 3 above this, is 200 feet wide and consists of
fissile and non-fissile, interbedded, argillaceous quartzites and argillites. The
next or No. 3 division of Figure 3 is 100 to 150 feet wide and consists of
fissile and non-fissile grey quartzites. No. 4 division is 250 to 300 feet wide
and in the northwestern part of the level consists of fissile and non-fissile,
interbedded argillites and quartzites. Above this are fissile and non-fissile,
grey quartzites exposed for a width of 200 feet. This upper quartzite may
