LAKESIDE COPPER.
Salt Lake and Ogden Parties Have q
Promising Property.

PROMISING IFoI'crts'
The local parties interested IN the
property OF the Lakeside Copper com
pany, situated on the Promontory
Point west Of ogden have become
very much encouraged since Prof, j.
III. Weber made an exhaustive OK
animation of the ground and sub
mitted his report II will be observed
from the following extracts taken
from the document that Prof Weber
believes the Lakeside Is PROPOSE
ton of more than ordinary merit. He
says:
II thoroughly sampled all the ex-
posures of the ore. bringing to the
city a quantity of material for ex-
permental purposes, and Tor uscer-
tanning the exact values contained in
them by an extensive series of assay

grade ore scattered in these collect-
ions We're carefully culled out. The
results of the tests made at IL dtf-
ferent places were as follows: SO per
cent. 2.10 per cent. 1.99 per cent. 50
per cent. Los per cont, sos per cent.

places need need not be worked. the
average Is carried up to 2.l9 per cent.
However, 1 always insist upon safe

therefore, cut the average down TO
LEO per cent for further calculation,
This will give US 80 pounds of cop
per to the ton. While 20 cents per
pound can be realized on copper at
the present market. II will certainly
be safe to estimate our doructs at Is
cents per pound. This will give us an
average of $3.50 per ton.
Il have been engaged for several
days and still am determining by
practical tests the teaching quality OF
this ore. and fiud that the deleterious
elements, such as lime. manganese
and iron oxide, found IN the ores of
other places, which have Wondered

side. 1t is an ideal teaching ore. The
chief constituent OF the ore is silica,
an element greatly detrimental In
the smelling process. but which is no
obstacle to the economy of the leach-
ing method of extraction.
las late as 1890. when the idea of
cyaniding gold and silver ores was
preached, 1t was hOoted at by the
masses. but today hundreds of mills
are being reared all over the world,
and such places as Cripple Creek are
now shipping their dumps, which had
been thrown out as waste, TO the cy
anding mills for treatment. 1t Is
estimated that no less than 100000
tons a. Cripple Creek alone are being
subjected to this new process.
while the copper teaching pro-
