Expert Pierce for the Reorgan-
ization Committee Makes
Splendid Report on Property
SAYS THAT THE ORE IS THERE
NO DOUBT THAT MINERALIZED
PORPHYRY UNDERLIES RHYO-
LITE CAP, AND SAYS PROPER
TY Is WELL WORTH PROVING.

The report of Richard T. Pierce.
the engineer engaged by the re-
organization committee of Ely Cen
trail Copper company to examine its
property, has been made and copies
of 1t are being sent out to the stock
hiIders. The report is a very
strong one in favor of the property;
and corroborates the reports and
theories and findings of the engineers
of the old company. The following
excerpts from the report will be read
with interest:
'It Is not now a theory or question
whether mineralized porphyry under
lies the rhyolite cap or flow extend
ing eastward from the Copper Flat
Fault" to the limits Of the Ely Cen
trail claims, at the southeast end Of
the groups. The fact that minerali.-
ed porphyry does underlie the rhyo-
lite in that area is fairly proven by
the results of drilling B hole, the
evidence of porphyry showing under
the rhyolite at the east end Of the
Tip-Top claim, and the developments
in the Zack shaft of the Ely Con-,
which is but 21O feet east of the line
of the Tip Top No. 2.
II am convinced that Ely Central
ground east or the fault carries min
eralized porphyry under the rhyo-
lite cap, but 1t remains to be proven
whether or not 1t is commercial.
consider that an area of 1900 by l.
900 feet, minimum extent, at the
southeast end will be found to con-
tain mineralized porphyry, with rea-
sonable assurance that comemrcial
ore will be had in it,"
The foregoing is in regard to the
Eureka workings, and the engineer
advises, if arrangements can be made
with the Ely Consolidated, to do the
exploratory work through the Zack
shaft. He made full examination Of
the Zack in all its workings, and
says:
"The deposits cut through by Zack
shaft all run directly towards Ely
Central ground, dipping west at vary
ing angles, bringing them closer to-
gether. as they go west, and it is a
most reasonable proposition that they
are and will be found in Ely Central
claims
Since this report was made they
have encountered the vein at the GEO.
foot level In the Zack shaft, the con-
nection having been made week ago
AS yet the values are not large; but
1t is expected that they Will improve
as drifting on the ore progresses.
Mr.. Pierce also likes the Clipper
and Monarch country. In speaking
of the Clipper. he says:
'The width of the ore, as demon
strated by shaft work and The north
and south drifts from the vest cross
cut. is 65 feet. The dump at the
Clipper showed between 20 and 80
tons of ore extracted from the diff
ferent openings on the 220-foot level,
some of which is pretty fair. The
bulk of 1t is heavy in iron and there
is some chalcopyrite ore to be seen
All of the ore shows evidence of
teaching. One piece of chalcopyrite
taken from the dump assayed IA
ounces in gold and 1.10 ounces in
silver, total gold and silver value
of 1854 and $50 per cent of copper.
"On the same jasperoid belt with the
Clippers is the Monarch Fraction and
the Monarch. With the exception of
a little work near the surface on the
Monarch, the ground covered by
these claims is unproven. Some of
this surface is included in the acre
age wanted by the Nevada Con-, for
dumping purposes, and which would
