WILL BECOME
A COPPER CAMP
Don Mcguire Speaks Enthusiastic
ally of Sierra Madre,
DISTRICT Is NEAR OGDEN,
MetaIlurgiat Believes Some Of the
Largest Wines IN the state WIN
lie Developed there

Don Mcguire the well known geolo'
gist and metallurgist. has expressed the
opinion. while in the city a few days
ago. that some of the largest copper
mines In the state wil be developed In
the sierra Madre mining district which
is located In the Wasatch range Of
mountains north Of Ogden
MI Mcguire has been managing a
number Of properties there for several
years and he is getting TO the point
where the development is getting inter-
esting. During the time that he has
been Interested IN this region he has
displayed little ostentation, but has
gone along IN quiet easy manner but
with the profounde8t confidence that the
district would become an important pro-
ducer OF mineral
owing 10 the deep SHOWS which M
the canyons and goIges the camp Is in
accessa Die In the winter, at least with
out sonic difficulty, and for that reason
little work has been carried on there
during the frigld season Of the year,
but with summer here again activity Is
the orler OF the day at the Boston,
Maghesa Midland, Santa Maria, North
land. Prince OF India, and Boilermaker
properties.
TO many Utah mining men little Is
known Of this extensive mineral bearing
country There are some who have
never even heard OF Il, others may have
done 20. but thought II Of little conse-
qutnce In a contribution to the Salt
Lake Mining Review recently Mr.. Ma
gulrc gave a description of this inter-
cstlng district, which contained the fol-
lowing
Comprising a part each Of Boxelder,
Weber and Cache counties IN northern
Utah, lies a very extensive mineral
bearing country, which has hitherto at
tracted but limited attention It's west
ern border extends down 60 the western
base OF the WasatCh range. OF which
Sierra Madre mountain constitutes
part. and where We find in the old SVEN
lie and schlst0se measures the Prince
OF India, Macmillan, Emma Nevada.
Boston, Maghera, Santa Maria, Next
can and other groups Of mines which
lie In the old formation, and higher up
toward the summit We find the Eldora-
do, Cashling, VultuTe, Uwanta, Devils
Neck and other groups IN which silver,
lead and copper abound while only gold
and copper exist near the base OF the
mountain.
THE measures toward the summit
show quart2lte of the cambrlan age and
above this the siluran limestones ana
clay shales capped by an extraordinary
M .f
though 1t might have been thrown w
from tremendous assure In the lime,
slate and syenite. through all Of which
the great Eldorado assure passes from
east to west This mineral bearing axis
crossing Eldorado peak, strikes north
eastward through spur or saddle-lke
mountain which separates Cache val
ley from Ogden valley This zone ex-
tends forward In an easterly direction
for about q miles, being prominent by
a series Of assures that exist IN the por.
phyry slate and quartzites that consti-
tute the formation OF this extensive
country.
The area Of this part Of Utah so min
eralizsd is about 20 miles In extent
Well toward It's eastern limit We reach
la Plata where phenomenal masses OF
iioat silvcr-bearing lead ores, are found
In the drift which covers series OF low
limestone hills and what is known az
la Plata basin Ina this same locality
veins come 10 the surface In which high
grade copper ores are very prominent
Strange as q may seem, hitherto very
little work has been done at La Plata
and no work done upon the extensive
series Of veins that are found to the
westward in The quaugite and porphyry
measures extending from the high la
Plata plain down into Ogden valley and
across the Nasatch range 10 the Eldo-
RADIO mine ana its associates on that
