of the series, where body of iron ore
is exposed % 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 its 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 oxidized sider-
lite.
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
in such strong persistent assures
see no reason to doubt that they will
develop into profitable ore bodies at
depth.
For the development of this series
Of veins, deep cross cut tunnel that
is equipped with a 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 depth of 300 feet from the
outcrop on the dip of the vein; and If
the ore resources it displays are any
criterion of what may be expected from
the larger and richer veins that over
lay it. the Lawrence is certainly des
tined to become very important pro g
Queer of very desirable lead silver min
erals.
1.-The 300 foot drift referred /, on
the small foot wall vein carries con-
tinous ore throughout it's length,
pirching 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 a
dump of concentrating ore estimated
to contain a thousand tons and judg-
ing from some pan tests will probably
mill from to 10 per cent lead A
small stope 40 feet long and Is feet
high has been made on this drift to
test out the production capacity of
the vein. In addition to the fine lot
of rich concentrating ore produced,
small carload of hand picked mineral
recently shipped which / am inform
ed sampled 71.8 per cent lead and III
OF. to the ton of silver; shipment was
made to the East Helena smelter and
returned a net profit of $1,000 over
and above freight and treatment
charges. This ore was clean course
grained galena quite free from zinc
and other Objectionable sulphides and
presents a splendid evidence of what
may be anticipated in the larger and
stronger veins of the series which will
be intersected by the further extern
sion of the main crosscut tunnel at
depths ranging down to two thousand
feet on the dip below the apex
"At present the mine Is idle pending
the erection of a 50-ton concentration
plant, the concrete foundations for
which are now being laid
1T seems pity that such an i'm
inent prospect of big and profitable
lead ore resources should lack the ne
cessary capital for its extensive devol-
opment with such splendid prices as
at present prevail
In conclusion, l consider the Law
renee property one Of the best lead
silver CANDLES in the state, and with
sufficient capital and an energetic in
telligent campaign of development, it
is likely to reimburse its sponsors
very handsomely.
