and equipment and warranted by of the phe
nomena showing at this level which nearly 1000
low the apex of the VEIN The No tunnel in which this great
station equipment is placed in the footwa of the Morning
mill elevation of about 100 feet vertically above the
Occur Aene valley at this point From the big station the
new line of development is through large we'll appointed
three compartment vertical shaft which has already sunk
400 feet and two levels opened where the shoot has shown
remarkable expansion in width and apparent peanency
and in connection with No. shows continuous channel of
rich lead bearing concentrating 1900 feet long and varying
from to so feet in width The unfortunate change the
character of the below this No. level to be depoed
but is by improbable that this finely crystazed
complicated mixture may be due to local crushing and tile
subsequent injection of secondary silica resulting from fault
Tor gneous intrusion yet to be found and the may change
again at still further depth to simpler combination for the
reason that in spite of this great depth of 0o0 feet the
bottom levels of the Morning body is still within Revett
quarze and should have at least 1000 feet of the favor
able clean bearing Burke formations to penetrate in
depth and within distance of and half miles horizon
tally north from this condition in the Morning vein the leca
vein developed still 1000 feet deeper in the ground and
an the simplest and ceanest of concentrating and crude
shipping found in the Occur Alene district Expert
ence in other deep mining operations in Idaho in deposits that
attributed to hot ascending mineral solutions has shown
particularly in the Snker tunnel development at Silver City
that the crystal forms contained IN the increase size
greater depth added below certain horizon and the in
in the quantity Of zinc and iron phes at this point
safe criterion of permanent change shown by the
perence at Wardne where the upper levels Of the Bunker
Hill lode produced penazed showing of with the lead
iphides and the deeper levels contain hardly any at
all This district further shows the Miners Delight claim
on the hanging wall side of the Sullivan bodies in shall
low surface tunnel body of nearly solid pyre 200 feet thick
while the practically free from pyrte 5000 feet below
the crest of the lode These contrasting conditions of min
zaon the district holds out the hope and prospect
hat e present complicated characteracter Of the
icing encountered in the Morning mine may be the result of
oca horizon of alteration that will again be replaced
further rept with of clean character with less
ondary silica and susceptible Of much easier separation
STAR MINE
Another very interesting deposit Immediately tribu
Muan is that of the Star mne situated the
and only few hundred feet west of the vets end Of the
great Morning body The Star vein has been developed
by crosscut utnne at depth Of 800 feet where well defn
ed shoot five to Is feet width and 500 feet in length has
een disclosed containing the characteristic features of its
great neghbor in structural appearances and contents and
mas far shown complicated character of ore open
ID in the lower level of the Morning mine Ia fact this
)ody in closer association with surface exposure of Burke
uarze than the Morning and may experience the OBJ
ectonabe change encountered at the Morning until the bot
of the Burke quarze horizon is reached in it's further
)oration Negotiations progress at this time for the
tunnel to be driven in from convenient elevation
lbove the valley and the consummaon Of this pan Judging
other development experiences of the district should
ut in opening deposit of great value and lasting quail
ties that should greatly stimulate the business interests of
Nullan.
