RECLAIMS MINE
AND SAVES CAMP
Splendid Record of Salt Lake
Engineer at a Ruined Thun-
der Mountain Property.
BRINGS ORDER FROM CHAOS
AND HAS ALL MOVING RIGHT IN
NINE MONTHS.

Less than ten months ago Captain John
Treweek, the veteran mining engineer and
expert of this city, was employed by the
Belle Of Thunder Mountain company to
take hold of the property and see if he
could not straighten out its badly tangled
affairs. mill had been built so had
q tramWay, and the mine had been well
opened, but there was no ore. The mill
was a miserabIy designed affair and the
tramway would not work
The company was blessed with means

wrong from the tUTn-lOOse. and the re-
port went broadcast over the country that
the SUnnyside mine the COmpany's prop
eTty, was no good. that The district was
no good, and that everybody connected
with the camp was a faker When Cap
tain ITeweek was asked to take charge
ne insisted first on ma king an examina-
lton Of the property on his own account,
QeteTmlned that, If reports were true,
he would have nothing to do with it
he finally decided that a mine could
BE made Of the property and that the
ores could be treated at q handsome
profit If certain changes were made in
the methods of treatment. The tram
could be easily made to perform its fuHC-
tlOnS and everything could be brought
out all right providing he could De given

The ore seems peculiarly adapted to the
