mines Of that locality did not have the

and process Of treatment have not been
yet completed in the chief mines OF that
district
In the Sierra Msdre district there
are about 800 mineral locations. with
nine legally Incorporated companies do
ing active work. These are the Ell
dorado, Napoleon Santa Maria, south
ern Pacific. Prince of India, Great
Northern Elkhorn, Midland, and Sier-
IA Madre companies; all lying on the
western slope Of Sierra Madre noun
tain. The district itself lies about half
way between ogden and Brigham city
in Boxelder county, and, about forty
five miles north Of salt Lake city.
The heavy work OF the District dur
ing the year has been carried out i'm
the Napoleon and Santa Maria. These
properties lie adjacent, and, the miner
alization occurs I'm series Of assure
veins IN each. IN the Napoleon gold,
silver and copper are the metals show
ing IN the greatest value and I'm the
Santa Maria gold, silver lead and cop

on the Napoleon during 1907 "a very
large volume of work has been done,
although this company is Incorporated
under the laws Of Utah, yet most Of
the stockholders are residents of Illi-
nois and Iowa The company may be
considered close corporation.
These groups OF mines lie on the
steep mountain side, the mineral wealth
IS found In three very wide copper
bearing lodes. two of which run paral-
lei and the third strong cross country
vein that faults the parallel lodes.
-Four tunnels have been driven on the
veins, the three upper being known as
levels Nos J, and 3, and are driven
at intervals along the Napoleon lode
distance Of about 5000 feet, and still
lower down, there Is now being driven
what is locally known as the Illinois
tunnels this VIII be the main ore adit
OF the property, and viii connect the
mine with the tramway.
The makeup OF the ores OF the Ma
poleon veins runs from 81 to 81 gold and
from one to two ounces silver and from
? TO 10 per cent copper the work being
down is OF very substantial charac-
ter
The tramway now being built viii
easily discharge at the lower terminal
300 tons every 10 ] Irs, and when tho
connections are made between the hi
nois tunnel level and No / the works
can easily send out that amount Of
tonnage for reduction 10 the concentra-
tor In the upper workings OF the
property there Is a large volume OF ore
sufficiently high grade TO smelt with
out concentration.
Notwithstanding the depression that
has come over the mining interests Of
our country the Napoleon Copper COM
pany is going forward with develop
ment work and expects To have ifs
property in tho production slopes IN
the early summer of 1908
ANOTHER ACTIVE PROPERTY.
The Santa Maria Gold & Copper COM
pany, whose property lies southeast Of
the Napoleon. has gone forward with
IT'S improvements during 1907. and the
work planned for the year 1908 takes iu
very large scope of development and
Improvement.
This company owns "a large area 81
ground, and within lts own borders
seven assure veins run from east TO
west parallel through the gneiss rock
that constitutes the base rock of the
mrountain. IN the eastern part Of tho
property is "a continuance ~ the Edo
RADIO silYer-lcad vein for about 1000
feet The sllycr-lead ores OF this vein
IN the Santa Maria are abundant and
rich enough for profitable working
