13-30 - Cascabel Project Update -- Alpala Prospect - Drill Hole
CSD-13-005 Intersects Significant Visual Porphyry Copper
Mineralization Over 345 Metres to Date
=======================================================================
Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc.
("Cornerstone" or "the Company") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF)
reports partial visual results for drill hole CSD-13-005 at the Alpala
prospect within the Cascabel Project, the Company's copper-gold
porphyry exploration project in northern Ecuador (refer Figure 1).
Assay results for this hole have not yet been received.
Highlights:
- Pervasive quartz veining and intermediate to strong copper sulphide
mineralization has been observed in the upper part of hole CSD-13-005:
- 345m interval (75-420m) containing porphyry copper-gold-related
quartz veining which is open at depth.
- Intermediate to well-mineralized chalcopyrite and bornite observed
from 249m to 349m.
- Higher grade intervals expected to be associated with zones of more
intense sheeted and quartz stockwork veining.
- Drill hole CSD-13-006 has been sited and the drill pad ready for
mobilization of the drill rig once hole CSD-13-005 is complete.

Drill Hole CSD-13-005 Visual Summary
Drill hole CSD-13-005 was sited to test the depth extension of the
intersections previously obtained in the first drill hole at Alpala,
CSD-13-001. Hole CSD-13-001 was drilled towards the southwest with a 60
degree dip angle, while hole CSD-13-005 is being drilled with the same
azimuth but at a much steeper dip angle of 85 degrees. CSD-13-005 is
being drilled to undercut the mineralized zones in hole CSD-13-001
(upper zone: 104m at 0,37% Cu and 0.38 g/t Au, including 34m at 0.46%
Cu and 0.50 g/t Au; and lower zone: 100m at 0.65% Cu and 1.00 g/t Au,
including 58m at 0.96% Cu and 1.67 g/t Au), and to provide a deeper
test of the mineralized corridor that has been identified to trend
through the Alpala Creek region.
The current planned depth for drill hole CSD-13-005 is 850m. As of
Thursday November 28th the depth was 454.7m and a further drill hole
length of 400m is envisaged, or further while the hole is in
mineralization.
The geology in the interval 0-420m down hole has been reviewed on site
during the past week, and the Company is pleased to announce the
following observations:
- Various copper sulphide minerals (chalcopyrite, bornite and
chalcocite) have been observed in the interval from surface to 420m
depth, the current depth at which the core has been observed at the
Rocafuerte site office.
- The interval from 75m depth to 420m depth exhibits significant
intensities of stockwork and locally sheeted quartz veining, with
logged vein densities varying from 2 to 35 veins per metre, and with
average logged vein densities between 137.2m and 395.6m being over 10
quartz veins per metre (examples of some more highly veined intervals
are shown in Figures 8, 9 and 10).
- Chalcopyrite is the most dominant observed copper-sulphide mineral,
occurring as inclusions within many of the quartz veins as well as
disseminations in the host diorite intrusion. Bornite and chalcocite
(copper-sulphide minerals with 66% and 80% copper content respectively)
are also observed in several zones (from 137.2m to 226m and from 256.9m
to 349.6m).
- The interval from 75m to 420m is characterized by potassic
alteration, with abundant magnetite relic in the drill core. The
potassic alteration has been strongly overprinted by lower-temperature
phyllic alteration that has converted magnetite to hematite and
potassium feldspar to sericite micas.
- While grades are unknown at present, the Company is pleased with the
visual results from hole CSD-13-005 to date.
Figure 3 is a northeast-southwest cross-section through holes
CSD-13-001 and CSD-13-002 at Alpala and illustrates the concept and
target that is being tested with hole CSD-13-005.
Present interpretations are that Mo soil anomalies in the Alpala Creek
area, supported by more restricted Cu and Au soil anomalies, define an
approximately 300m-wide north-west trending structural corridor that
appears to be mineralized at shallow levels. In the present area of
drilling at Alpala, there appears to be at least two, and may be
several more, steep zones of sheeted porphyry quartz veins that exhibit
higher grade, with the intervening areas being characterized by
less-aligned and more stockwork-like veins. These steep zones of
sheeted veins and their envelopes of stockwork veins are likely
controlled by northwest-trending structures and collectively define a
300m-wide mineralized corridor at shallow levels (see Figure 3) that
may extend over a strike length of around 600m at surface based on the
strike extent of a major associated molybdenum soil anomaly.
The mineralized corridor exhibits strong molybdenum (Mo) anomalism in
surface soil samples since Mo is a relatively immobile element in the
soil profile (Figure 3).
The northwest-trending faults and sheeted sets of well-mineralized
porphyry quartz veins are interpreted to tap into an inferred larger
body of mineralization at depth that is the principal target for the
current hole (CSD-13-005) and the next hole (CSD-13-006) that will be
sited north of holes 1 and 5 and which will test a coincident
molybdenum and gold anomaly at surface (Figure 2).
Other high quality targets exist on the southeastern, northeastern and
northwestern parts of the magnetic complex.
About Cascabel
SolGold Plc holds a 50% interest, and can earn up to an 85% interest,
in Exploraciones Novomining S.A. ("ENSA"), the Ecuadorian subsidiary of
Cornerstone that holds 100% the Cascabel concession.
The Cascabel project is located in north-western Ecuador in an
under-explored northern section of the richly endowed Andean Copper
Belt, 60 km northeast of the undeveloped NI 43-101 compliant inferred
resource of 982 million tons at 0.89% Cu Junin copper project.
The Alpala Prospect exhibits surface mineralization and alteration
patterns indicative of porphyry copper-gold systems and has a similar
footprint to large porphyry systems around the world.
Brooke Macdonald, President of Cornerstone, commented, "This year we
have re-focused Cornerstone exclusively on our Ecuadorean and Chilean
projects, which we believe have the potential to deliver superior
returns to our shareholders. Changes earlier this year to the Mining
Law in Ecuador, to cap government royalties and to clarify that the
windfall profits tax applies only after mine payback, have removed a
large obstacle to investment in the mining sector. The potential
geological endowment of Ecuador remains unknown due to under
exploration but may be unparalleled."
Qualified Person:
Yvan Crepeau, MBA, P.Geo., Cornerstone's Vice President, Exploration
and a qualified person in accordance with National Instrument 43-101,
is responsible for supervising the exploration program at the Cascabel
project and has reviewed and approved the information contained in this
news release.
Logging, sampling and assaying
Hole CSD 13-005 was drilled using HTW and NTW core sizes (respectively
7.1 and 5.6 cm diameter). Geotechnical measurements such as core
recovery, fracturing, rock quality designations (RQD's), specific
density and photographic logging are performed systematically prior to
assaying. The core is logged, magnetic susceptibility measured and key
alteration minerals identified using an on-site portable spectrometer.
Core is then sawed in half at Cornerstone's core logging facility and
half of the core is delivered by Cornerstone employees for preparation
at Acme Analytical Laboratories (ACME) affiliate laboratory in Cuenca.
Core samples are prepared crushing 1 kg to 80% passing 2 mm (10 mesh),
splitting 250 g and pulverizing to 85% passing 0.075 mm (200 mesh)
(ACME code R200-250). Prepared samples are then shipped to ACME in
Vancouver, Canada where samples are assayed for a multi-element suite
(ACME code 1E, 0.25g split, 4-acid digestion, ICP-ES finish). Over
limit results for Ag (> 100 g/t), Cu, Pb and Zn (each one > 1%) are
systematically re-assayed (ACME code 7 TD1 or 7 TD2, 4-acid digestion,
ICP-ES finish). Gold is assayed using a 30 g split, Fire Assay (FA) and
AA or ICP-ES finish (ACME code G601).
Quality assurance / Quality control (QA/QC)
The ACME affiliate preparation facility in Cuenca was audited by
Cornerstone prior to the start of the drilling program and ACME is an
ISO 9001:2008 qualified assayer that performs and makes available
internal assaying controls. Duplicates, certified blanks and standards
are systematically used (1 control sample every 15 samples) as part of
Cornerstone's QA/QC program. Rejects, a 100 g pulp for each core sample
and the remaining half-core are stored for future use and controls.
