exceeds the gold. and the percentage of

(c) The typical ore of the camp. as
SOLD by the LIE Roi, War Eagle, Iron
Mask or Josie, is divided into first
class and secOnd-class.+ The first-class
consists of nearly massive fine-grained
pyrrhOtlte and copper pyrites. some
tllneS with little magnetic or mis-
plckeL with more or less quartz and
calclte. In this class of ore, as got
from the lowest workings Of the LIE
ROi, the amount of quartz is much
hlgher, the smelter returns giving Al to
oZ.S per cent silica, and 20.6 to 268 per
cent FeO., but this is proving the best
ore IN the mine; the average smelter
returns were on 1000 tons, &c o. OF

Quoting freight and treatment charges.

large number Of st. Paul people
have had their attention called to the
new field for investment. and already
considerable holdings have been ac-
Qu1red locally in the vicinity of Ross
land. 1t is notable and significant
fact that those who are most interested
and who have demOnStra ted their faith
most largely by purchases, are those
who have had the best opportunity to
test the richness Of the field for them
selves. 1t is said that the local men
who have the largest Holdings include
number of men Identified with rail-
road interests, and especially those
connected with the transcontinentaI
systems whose business takes them
most often to thes West and into the
Rossland country. up TO this time the
faVorlte property among St. Paul in
vestOrs has been the Abe Lincoln,
which is regarded not only here but
on the ground, as one of the most
promising among many rich mines.
On the question Of the metallurgical
treatment Of the ore, Mr.. Carlyle, of
fetal geologist Of British Columbia.
says:
1.-THE destiny Of mtning operations
will depend, to a very great extent,
upon the means of transportation, and
then upon the cost Of metallurgical
treatment, for a large amount Of low
grade ore is promised, and the posi-
bility of treating such ores at a low
figure to leave fair margin of profit
must attract the hest endeavors of
the metallurgist. The ores containing
a high percentage Of sulphides will be
very desirable, and should command
the lowest smelling charges. but in all
probability the great bulk of the Trail
Cree k ores will be Of the mixed class,
