Glengarry Mine

Coming around the Red mountain TO the
/ east side there are several properties which
present some very attractive showtngs Of ore
We then reach the Lula Pass and the Glen.
1 garry mine. This property has been developed
/ for years by inefficient management but late
/ ly has changed hands It needs capital to
start production There is some Of this serec-
| tized ore and some was shipped several years
ago. concentration has been built the
! equipment being furnished by the Denver
Equipment Co. The present management Is
an able group Of men, and they should sue
coed in the enterprise.
The mine is developed by tunnels and has
a great deal Of low-grade ore developed,
carrying gold, silver and copper values, the
ore needs fine grinding, and requires ex-
perienced metallurgist to supervise operation.
Large TONNAGE should be handled to get ef-
ficiency. The formation Is q contact between
the monzonite and the gabbro, with much
altered rocks. decomposed gabbro. Some high
grade ore was shipped years ago as copper
gold ore.
East Of the Glengarry mine rised Scotch
Bonnet mountain. and behind It the lofty
peaks OF Granite peak, 1890 feet, highest
mountain in the state Of Montana.
South Of the Glengarry mine and along
the road Is located the Threadenick mine; no
operation has been going on there for some
time. This mine is developed by shaft and
veloped and should be put into production by
additional work and repairs underground,
and q mill could be erected later on. Some
good copper-gold ore came out Of 1t in the
South of the Threadenick mine is Sheep
mountain, a mass Of Gros Ventre granite.
This formation as well the valley between
1t and the Scotch Bonnet mountain present
some parties were diamond drilling some
ground on Sheep mountain.
We have now reached the east side Of the
Daisy, Homestake and Henderson mines, and
one can have an idea Of the tremendous tom
mage In this property. The lower camp has
a large compressor plant buildings for camp,
a loo-ton primary ore bin, large Eyratory
crusher, conveyor and q two-compartment
IL 00-ton ore bin; all these are at the Hen
derson tunnel level. Some TOO feet vertically
above is the Homestake tunnel and Daisy
workings with the upper terminal Of the
tramway, which delivers the ore to the bins
below at the Henderson tunnel level.
From this crushing plant tramway was
built to transport the ore to the smelter
plant some 1900 feet away. The new COM
pany will build its flotation and cyanide plant
along the ore bin which will be part of the
mill The method to be used win be selec-
tive fotation, and probably cyanidation OF
the low-grade iron concentrate. The copper
lead concentrate Will go to the smelter as well
as the zinc concentrate.
Following the Clarks Fork OF the yellow
stone river valley and going south and along
the east side Of Henderson mountain there
are numerous GOOD ore showings and pros
poets worth investigation. These ores carry
gold. silver, copper and some lead.
We then reach the smelter of the old
Western Smelling and Power Co. Of which
Or. Tanner was president and who developed
the Daisy and Homestake mines The country
between the smelter and the highway presents
several good prospects as well as placer de-
posits. Below the highway and south Of it.
one goes down the Clarks Fork of the yell
owstone river and into Wyoming Along
the course Of the river there is placer ground,
some OF which has been tested with good re-
suits, and some Is being worked.
From there one can return to Cooke City
after having travelled IA miles, making q
complete round trip Of the district.
This district until recent years was idle
because Of lack Of transportation and the
lack Of knowledge Of the vast mineral re-
sources Of the region.
