of the series, where body of iron ore
is exposed 20 feet thick which includes
a bed or horse of pure limestone two
feet thick seven feet above the foot
wall. The lower portion of this vein
does not show any lead as far as de-
veloped at this particular poin-. but
this vein carries galena in several
openings along it's course. The IA feet
above the limestone inclusion is richly
sprinkled with galena and carbonate
ore and will probably average 40 per
cent iron largely clean oxioized sider-

THE ore and gangue of these veins
are identical in appearance with some
of the best surface manifestations of
the Mullan and Wardner districts and

see no reason to doubt that they will
develop into profitable ore bodies at

For the development of this series
Of veins, a deep cross cut tunnel that
is equipped with small compressor
plant, has been started near the foot
of the mountain and extended in nearly
700 feet. At 3e2 feet from the portal,
the first and weakest vein of the series
has been cut and drifted upon for 300
feet at a depth of 800 feet from the
outcrop on the dip of the vein; and if

the small foot wall vein carries con-
tinous ore throughout it's length,
pinching down to a few inches in
places and swelling to a maximum
width of six feet of fine concentrating
ore with fat streaks of clean, coarse
grained galena fully six inches thick
in places. This drift has produced
