Gold Silver Values Returned From New York Canyon Sampling
VANCOUVER, Aug. 20, 2012 /PRNewswire/ – Canyon Copper Corp. (“Canyon” “Company”) (TSXV: CNC) (OTCBB: CNYC) has carried out a
preliminary rock sampling program on copper skarn mineralization
located on its New York Canyon Property, Mineral County Nevada (1293
claims with an area of approximately 66.000 hectares or 26,000 acres).
-- Significant gold and silver assays were returned from rock samples over 3 km belt of of skarn deposits. -- Copper skarn belt includes Copper Queen-Ideal Mine, Champion Mines, Longshot Ridge Resource Area, and the New York Canyon Basin. -- Gold grades up to 0.5 g/t and silver grades up to 74 g/t (approximately 2 oz/st). -- Copper assays indicate better than expected metal recoveries into solution from single acid (H2SO4) leach (acid consumption not defined by assay method)..
32 samples were collected from dumps, surface and underground workings
at all of the most significant copper showings in the skarn belt.
Except for the Longshot Ridge, much of the belt has not been drilled at
a spacing suitable for testing this type of mineralization. The target
is a higher grade and lower tonnage mineralization compared to the
porphyry style target of Conoco, Phelps Dodge and other earlier
workers. Chalcocite and bornite skarn mineralization associated with
some oxide copper can offer potential as a feed for a copper leach
operation which could produce premium cathode metal with a solvent
extraction copper electro-winning plant..
The purpose of the sampling was to determine if any precious metals were
present in the skarn mineralization and also to type the pathfinder
elements associated with the copper or precious metals. The table below
indicates metal associations in samples with possible economic grade
copper mineralization in 16 (50%) of the samples.

(ACID SOL* )(The Cu total grade was measured from a sample digested with a strong
four acid attack. The calculation of the acid soluble component is made
by dividing the total copper value into the copper value of a one acid
sulfuric acid digestion of that sample and multiplying by 100 to
convert to a percentage for the copper recovered from the sample by the
one acid attack. This analysis is carried out because it gives a guide
to the metal recovery that may be achieved in a leach plant.)
(The results above indicate that the better silver results appear to
occur on the east end of the skarn system in the New York Canyon Basin.
The better gold values appear to be related to the Champion mines area
in the central part of the skarn system and possibly at lower original
elevation or closer to any potential copper porphyry metal sources.)
Upcoming programs for Canyon Copper:
Proposed Drill Program to start after further Metallurgical Work on
CNC had announced that it was permitting for a shallow reverse
circulation drill program at the Moonlight copper oxide deposit in
order to establish a resource estimate of the oxide mineralization in a
manner compliant with NI 43-101 regulations. The basic permitting
process has been started.
A review of earlier drilling results indicates potential for mixed
oxide, native copper and acid leachable sulphides in zones related to
higher grade structures mineralized by late stage mineralization. These
zones lie beneath the oxide zone defined by earlier studies of the
oxide cap at Moonlight (see News Release 25(th) March 2012) and could extend the leachable mineralization to depth..
Further metallurgical work and evaluation of the late stage
mineralization will be undertaken to guide the drill program. Sample
material from earlier core drilling is available for this work and
includes mineralized drill sections which have been well stored in
nearby facilities. Samples from this storage facility have also been
sent for assay for precious metals in several drill sections that were
only assayed for copper.
Property Scale Geochemical Program on New York Canyon Claims
CNC has started a geochemical program to cover the considerable area of
the New York Canyon claims with a survey of arroyo/stream sediments.
The purpose of the survey is to assess the potential for areas of
mineralization that may be associated with the several areas of old
prospects and workings within the claims. Gold and silver indications
reported above are associated with some moderately anomalous path
finder elements such as arsenic, bismuth and antimony. Analysis of such
pathfinders will be included in order to outline areas with gold
potential. The former Santa Fe gold producer is located on the north
boundary of the NYC claim block and reportedly was first investigated
as a base metal showing.

forward-looking statements because they are subject to a variety of
risks, uncertainties and other factors that could cause actual results
to differ materially from Canyon’s expectations, and expressly does not
undertake any duty to update forward-looking statements. These factors
include, but are not limited to the following, Canyon’s ability to
implement its proposed drill programs on the Moonlight Property and the
New York Canyon Project, Canyon’s ability to obtain additional
financing, uncertainty of estimates of mineralized material and other
factors which may cause the actual results, performance or achievements
of Canyon to be materially different from any future results,
performance or achievements expressed or implied by such
Cautionary Note to U.S. Investors Regarding Estimates of Measured,
Indicated and Inferred Resources
This News Release may use the terms “measured”, “indicated” and
“inferred” “resources.” We advise U.S. investors that while these
terms are recognized and required by Canadian regulations, the SEC does
not recognize them. “Inferred resources” have a great amount of
uncertainty as to their existence, and great uncertainty as to their
economic and legal feasibility. It cannot be assumed that all or any
part of an “inferred mineral resource” will ever be upgraded to a
higher category. Under Canadian rules, estates of “inferred mineral
resources” may not form the basis of a feasibility study or
prefeasibility studies, except in rare cases. The SEC normally only
permits issuers to report mineralization that does not constitute
“reserves” as in-place tonnage and grade, without reference to unit
measures. U.S. investors are cautioned not to assume that any part or all of a
measured, indicated or inferred resource exists or is economically or

THAT TERM IS DEFINED IN THE POLICIES OF THE TSX VENTURE EXCHANGE)
