PROVING ST. LAWRENCE
A GREAT COPPER MINE
SAYS DEVELOPMENT HAS PROV
Ed CORRECTNESS OF
HIS THEORY.

Henry M Lancaster. OF Saltese
manager Of the ST Lawrence Copper
Mining company accompanied by
Mrs Lancaster were at the Samuels
hotel Monday and Tuesday, returning
home yesterday morning Replying
90 questions regarding operations at
the ST Lawrence, Mr.. Lancaster ex-
pressed the greatest satisfaction with
results so far accomplished and alb
solute confidence that his geological
theory regarding the property will be
mlly verified through the consumma-
ton of the plans now being carried
out I'm fact. the disclosures made by
the work SO far have cOnformed iden-
tically to the conditions which he out
lined and explained in much detail in
a report to the stockholders over two
years ago This confirmation of his
theory which was the result of many
years experience as an engineer in the
mines of the Occur d'Alene district
and an exhaustive study of the St
Lawrence and Richmond ground. has
removed all uncertainty that might
have existed in his mind regarding
the final outcome As evidence of his
finn conviction on this point Mr..
Lancaster stated unqualihedly that
the St Lawrence VIII prove to be a
great copper mine At every stage
of development ne said his predictions
had been confirmed. The amount Of
ore SO far encountered conforms to
his theory and ne confidently looks
forward to find a large and perman-
ent ore body when the real ore zorA
is reached
Where Work Is Being Done.
Starting at the intersection of the
vein i'm the lower St Lawrence tun-
mel, a drift is being run easterly,
away from the ground which had
heretofore been regarded as the St
Lawrence mine The Lancaster the
DRY is that the st. Lawrence Rich
mond hill which forms a part of the
Idaho Montana divide was originally
1000 feet easterly and that it was
moved from its original location by
the pressure from a great intrusive
monzonite dixie which crosses the
vein east of the east end line of the
Silver Lake claim, one of the St Law
renee group. In connection with his
report outlining this theory. Mr..
Lancaster has prepared elaborate
maps showing the form and structure
of the hill as it stands and it con-
forms to position which he contends
ii once occupied above the ground
which he is now exploring with such
results. The drift has
just passed under a sag between the
two elevations and is now gaining
depth as it enters the original st.
Lawrence hill the ultimate depth
possible on this level being about 500
feet At this time the drift has been
advanced GAO feet the vein being well
lehned and carrying more or less ore
n places punches of ore have been
more than the width of
he drift, being largely oxide of cop
Der and some sulphide The face of
he drift is now within the Silver
AXE claim. leaving about 400 feet
c. the east end line. A significant
eature bearing upon the correctness
If Mr.. Lancaster's theory is the ap-
earance in the drift of primary cop
er ore the first that has been found
% the st. Lawrence, all the ore in the
ID workings being of secondary orr
in.
Mr.. Lancaster says that everything
the way of provisions and mining S
upplies is on hand at the st. Law :
,noe and i'm sufficient quantities to {
ieet all requirements until spring. s
he snowfall is very heavy along the q
iaho- Montana divide, which makes c
necessary to provide for the long
inter The company has good build
Igs and every facility in the way Of :
,ols and equipment. Eight men are +
DIV employed at the mine and every j
ing is in shape to continue develop ,
ent without interruption. q
