In botn the Zaclk and the Brilliant
shafts of tho Ely Consolidated Copper
company. important strikes have
been made, which are attracting con-
siderable attention from mining eX-
perts. The Zack orc shows the rich
cr ASSAYS, but the Brilliant ore has
been found in greater quantity. The
Brilliant shaft is now down nearly
500 feet and is 40 feet in ore, which
is looked upon as the primary forma-
ion of the district
CLAUS Jeldness, manager of the Ely
Consolidated mines, when asked
about The reported strikes in the
Xack and brilliant shafts, said
In the Zack shaft we have found
ore which | have had assaycd. Or"

The Brilliant shaft has iow
reached depth of 1875 feet. rhe
last f40 feet are in sulphide ore. The
last samples taken from the Brilliant
shaft assay up to 6 per cent copper.
The ore Is chalcopyrite which is
probably the primary ore enrichment
from which the chaleoeite has been
formed and enriched by upheavals
and the teaching process.
In all probability The ore that will
be found in the contact between the
lime and porphyry at Il greater depth
than the ore bodies created by The
secondary enrichment process will BE-
this chalcopyrite now encountered II
the Brilliant shaft.
The Brilliant ore being taken AT
near 500 feet in his contact and $50
feet below the water level, the prob
abilities are that it will be found in
the same contact in other mines in
this particular ore zone where the
ditions are similar.
THE Brilliant ore is ideal for
smelling and is the identical ore
which the great copper mines OF
British Columbia are producing. Ores
of this kind smelt easily and are de-
sirahle for fluXing with low grade
gold and silver ores.
The management of the Ely Con.
is preparing TO install pump at the
American shaft to pump out the wa
ter so that development can be con-
tinued in that shaft. When the wa
ter was first struck at depth of 800
feet, top swing bucket with a ca
pacity Of 20 gallons was used in an
effort to remove the water so that
The miners could keep at work.
With the top swing bucket 1000
gallons of water were hoisted in 24
hours. but this was not fast enough
20 keep the shaft cleared of water
and work was temporarily abandon
ed
The miners who were employed in
sinking the shaft are now engaged in
