VANCOUVER,
May 22, 2013 /CNW/ - Ecuador Gold
& Copper Corp. (TSX-V: EGX), (the "Company" or
"EGX") is pleased to announce completion of its previously
announced Phase I 13,000 meter drill program at its four priority
targets located within the Company's 8,300 hectare Condor Gold and
Copper Project in the Zamora Gold and Copper Belt, Southeast Ecuador. Assay results from drill
holes DSB-24 and DSB-25 have been released at the Santa Barbara
gold-copper porphyry deposit. Drill hole DSB-25 returned 212m
averaging 0.55 g/t Au and 0.11% Cu. This includes 50m that averaged
0.79 g/t Au. DSB-25, drilled to 704m, was collared 100m
southeast of DSB-22 that returned 484m of 0.80 g/t Au and 0.13% Cu
(EGX News Release April 10,
2013). DSB-24 drilled through and along intervals of
lower grade gold in thick intrusive dikes but still encountered
292m of 0.38 g/t Au and 0.08% Cu. This hole was located 200m
northeast of DSB-19 where previous results showed 420m of 0.57 g/t
Au and 0.08% Cu (EGX News Release October
17, 2012). The Company has completed four more holes
at Santa Barbara to follow up on recent success in extending the
mineralized zone, particularly to the south and east. Assays
are awaited for four drill holes DSB-26 to DSB-29. EGX
results at Santa Barbara are summarized in the table further
below.
Phase I Drill Program Complete
(13,062m)
With the completion of drill hole DSB-29, the
Company has now completed its previously announced 13,000m Phase I
drill program and has commissioned Al
Maynard and Associates of Perth
Australia to prepare an updated NI 43-101 technical report
to update drill results and recalculate resources based on all the
drilling up to and including DSB-29. This report is expected
to be completed by June 30, 2013.
The Santa Barbara gold-copper porphyry deposit
is one of four targets including two epithermal gold targets (Los
Cuyes, and Soledad) in the northern part of the Condor Gold and
Copper concessions and the promising El Hito copper-molybdenum
porphyry target located 5km east of Santa Barbara. These four
target areas have been prioritized for resource expansion drilling
by the Company (see EGX News Releases, January 30, 2013 and March
5, 2013 for recent drill results at Los Cuyes and El
Hito). Project locations and drill hole plan maps can be
found in the project map section on the Company's web site at
www.ecuadorgoldandcopper.com and project descriptions and current
resources in the June 14, 2012
Technical Report at www.sedar.com.
Existing Resources
The Condor Gold Project contains a Measured
& Indicated Mineral Resource of 1.52 million ounces gold
(within 50.4 Mt grading 0.94 g/t gold). This resource is exclusive
of the above-mentioned Phase 1 Santa Barbara drilling. Additional
Inferred Mineral Resources contain 1.28 million ounces gold (within
28.4 Mt grading 1.4 g/t gold). The measured resource consists
of 54,000 ounces of gold (within 147.0 Mt grading 1.0 g/t gold) and
the indicated resources consist of 1.47 million ounces gold (within
50.3 Mt grading 0.94 g/t). For more information, please see
the Company's resource table at www.ecuadorgoldandcopper.com or its
Technical Report dated June 14, 2012
which is available under the Company's profile on SEDAR at
www.sedar.com.
These existing resources were also calculated by
Al Maynard and Associates in
June 2012.
Santa Barbara
The Santa Barbara Au-Cu porphyry deposit, which
shows exceptional promise, is emerging as the Company's flagship
deposit. Eleven drill holes have been drilled to extend
mineralization to the north, south and east of the current
resource. The table below has been updated to reflect the
results from drill holes DSB-24 and 25 while results for DSB-26 to
DSB-29 are pending. The company has commissioned an updated
resource calculation for Santa Barbara that is expected to be
complete by the end of June, 2013.
The Santa Barbara South Zone currently hosts an
inferred resource of 21.0 Mt of 1.00 g/t Au (675,000 oz) while the
Santa Barbara North zone (500m to the northeast), contains a
further inferred resource of 5.0 Mt of 0.90 g/t Au (145,000
oz). For further details see the Company's web site at
www.ecuadorgoldandcopper.com or the June 14,
2012 Technical Report at www.sedar.com.

long term price for gold.
- The true width of down hole interval lengths are estimated
to be approximately 25% to 50%.
The Santa Barbara South Zone remains open to the
north, east and south. Porphyry gold-copper mineralization is
hosted by altered basaltic andesite intruded by Jurassic intrusive
stocks and dikes. Major structural orientations are exhibited by
steeply dipping intrusive contacts, porphyry B-type quartz veins
and faults striking northwest and northeast. The 40km long
Zamora Gold and Copper Belt in Southeastern Ecuador is host to
Ecuacorriente's Mirador, Panantza and San Carlos copper porphyry
deposits and Kinross's Fruta del
Norte epithermal gold deposit of the same age. The Company
cautions that reference to the nearby deposits is for information
purposes only and there is no assurance that its Condor gold and
copper concessions will develop into economically viable producing
deposits.
El Hito
El Hito is a Cu-Mo porphyry system hosted in
diorite porphyry located approximately five kilometers east of the
Company's Santa Barbara Au-Cu porphyry deposit. The Company
has drilled five drill holes at El Hito in its PhaseI drill
campaign to follow up on four shallow discovery holes from previous
operators. The deposit remains open to the north and south
and further mapping to the north in particular has indicated the
potential to double the strike length of the known mineralized
system. EGX plans further drilling in its Phase II drill
program pending detail mapping of the diorite and alteration to the
north that is planned for June and July of 2013. Results from
DEH-05 to DEH-08 were released previously (Company News Release,
March 5, 2013) and the table below
has been updated to show the results from DEH-09, the last hole
drilled in Phase I drilling. DEH-09 encountered continuous
copper mineralization from 24m to the end of the hole at 560m
including 106m starting at 24m of 0.32% Cu and 1.06 g/t Ag and a
further 110m of 0.33% Cu and 1.71 g/t Ag starting at 368m.
Table 1 has been updated to include DEH-09 and
summarizes the assay results to date.

Los Cuyes
One drill hole, DCU-41 (see Company News Release
January 30, 2013) was drilled at Los
Cuyes where there is an indicated resource of 46.85 million tonnes
of 0.82 g/t Au and 6.19 g/t Ag (1.23 million oz Au and 9.32 million
oz Ag). Los Cuyes is a well defined epithermal gold deposit hosted
in lapilli tuffs and phreatomagmatic breccias related to
rhyodacitic intrusives and dikes and bounded on four sides by near
vertical faults. DCU-41 tested the potential to expand known
resources to the north where promising east-west structures
intersect rhyodacite intrusive dikes. DCU-41 was collared
approximately 50m west of the known resource and encountered 149
meters of 0.84 g/t Au starting at 132m adjacent to the known
resource including a 14.1m fault intersection grading 5.00 g/t
Au. The hole was drilled to 638.5m and encountered 5 more
narrow structures ranging in width from 0.5 to 3.4m with grades of
0.5 to 3.4 g/t Au. The company is planning further mapping at Los
Cuyes to define new drill targets.
Soledad
Three drill holes totaling 1935m were drilled at
Soledad. DSO-28 and DSO-29, drilled to the east and west
scissoring towards each other, were designed to test for extensions
of known mineralization in the southern part of the known deposit
in an area without previous drilling. Both drill holes
intercepted a narrow east-west trending corridor of previously
unrecognized and unmineralized phreatomagmatic breccia.
DSO-30, drilled towards the south, encountered 90m of 0.72 g/t Au
starting at 54m including 28m of 1.00 g/t Au before intercepting
the phreatomagmatic breccia. Epithermal gold mineralization
at Soledad is hosted in a rhyodacite intrusive. Soledad hosts
an indicated resource of 2.32 million tonnes of 1.33 g/t Au (99,000
oz) and 6.35 g/t Ag (474,000 oz) in two separate breccia bodies in
the northern part of the intrusive (see the Company's June 14, 2012 Technical Report at www.sedar.com
and maps at www.ecuadorgoldandcopper.com).
Quality Assurance
The Company has implemented a quality assurance
and quality control program to ensure that the transport, sampling
and analysis of all samples are conducted in accordance with the
best possible practices. Drill core is transported from the drill
by employees to the Company's secure core logging facility at its
camp where, after geotechnical and geological logging, it is marked
for sampling. The entire hole is sampled and core samples are
generally 2m in length, varying at geological contacts to between
1.5m and 2.5m and are split in half by EGX employees. One
half is retained in a secure storage facility and the other half is
transported by EGX employees or a bonded courier to ACME Labs'
sample preparation facility in Cuenca, Ecuador where the core sample is crushed so
that 80% passes a 10 mesh screen and a 250g split is pulverized so
that 85% passes a 200 mesh screen. From Cuenca ACME Labs
ships the samples to their laboratory in Santiago, Chile for analysis. The lab is
ISO/IEC 17025:2005 (CAN-P-4E) certified. Where appropriate, samples
are analyzed for gold by 30-gm fire assay with an AA finish and by
gravimetric methods for assays over 10 ppm. Samples are analyzed
for silver and copper by ICP-ES after a four acid digestion.
For silver assays over 200 ppm, samples are analyzed using ACME
Labs 7AR method consisting of hot aqua regia digestion and ICP-ES
analysis. Copper assays over 10,000 ppm are re-analyzed using four
acid digestion with ICP-ES finish (ACME Labs 7TD method).
ACME Labs are independent from the Company.
Under the Company's QA-QC procedures, samples
are submitted for re-analysis based on their proximity to a
certified reference standard that returns a value greater than
three standard deviations higher or lower than the mean value for
that standard. In addition, any two consecutive reference standards
falling outside the two standard deviation threshold will be
considered to have failed. Since every twentieth sample is a
reference standard, ten samples above and below a failed standard
will be re-analyzed. The same protocol will be applied to duplicate
samples considered to have unacceptably divergent gold values.
Periodically, random samples will be submitted to another
laboratory as an external check on the results provided by the
primary lab.
