The Philipsburg quadrangle is a 30.
minute area which Joins the south half
of the Helena Commute quadrangle
on the west Its eastern border rs
about a mile west Of Anaconda, and
its northern limit is just south of
Stone Station on the Philipsburg and
Drummond branch of the Northern
Pacific railway. The area is for the
most part mountainous, with eleva
tions ranging from 1900 TO 10000 feet
The central portion of the quadrangle
is drained by Flint creek, which flows
northeastward TO the Missoula river
Relatively low hills on both sides of
this creek furnish good pasturage for
cattle, and in the valley along the
stream are q number of hay ranches
where the harder grasses are Guilt

thickly cover the higher country, al

local needs, are of too small size to be

A number of mining camps are To-
Gated within the district, the most
important being Philipsburg. Gable,
Georgetown. Combination, Henderson
and Flint, and some of these were
among the first in Montana to receive
the serious attention of quartz pros
pectors. The valuable metals of the
ores of this district are silver, gold
and copper. Some of the ores carry con

In the summer and autumn of 1906.
while geologic mapping of the district
was being carried on by Messrs. T. G..
Calkins and D. L. Mcdonald, of the
United States Geological Survey, the
ore deposits were made the sub iect of
special study by Mr.. w. II. Emmons
The report on the Granite Bimetallic
and Ca bic mines, which appears in the
Survey S Contributions to Economic
Geology. 1862 (bulletin No. 315),
was prepared by Mr.. Emmons as the
result of that study.
The Granite Mountain and Bimetal
lie mines are about 212 miles southeast
pl lIlpSDuTH4 on the Slcep western
slope of Granite mountain, which rises
1000 feet above the valley of Flint
creek. Although located on the same
ore shoot and controlled from the first
by nearly the same interests, the mines
were worked separately until 1878,
when a consolidation was effected
since which time they have been op-
Grated as one. More than half of the
total mine production of the Philips
burg quadrangle Is credited to the
Granite mine.
Eight miles southeast of the Granite
mine and thirteen miles northwest of
the famous Anaconda district is the
Cable mine, from which some remark
ably rich ore has been taken, So far
as their larger structural features are
concerned, the ore deposits OF the two
mines are so unlike that they can
scarcely be compared. OF list Of 40
mineral varieties noted at the two
mines, % per cent are peculiar TO the
Granite, % per cent are peculiar to the
Cable, and 800 per cent are common to
both. Mr.. Emmons discusses briefly
the general character. distribution,
and relations of the ore deposits and
makes certain practical deductions Of
economic value. Prospectors. miners
and others interested in the subject
