Cascabel Exploration Update - Hole 14 returns 476m @ 0.63 %
copper and 0.65 g/t gold (1.14 % CuEq) - Hole 16 assays from 764m
to 1248m remain pending
=======================================================================
Ottawa, ON, Canada: Cornerstone Capital Resources Inc. ("Cornerstone"
or "the Company") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) announces the
following project update for the Cascabel copper-gold porphyry joint
venture exploration project in northern Ecuador, in which the Company
has a 15% interest financed through to completion of a feasibility
study. SolGold Plc is funding 100% of the exploration at Cascabel and
is the operator of the project.
HIGHLIGHTS:
- Final assay results from drill hole CSD-15-014 ("Hole 14"), testing
the eastern extensions of the Alpala Central deposit, returned the
following intersections:
- 768m @ 0.50 % copper and 0.45 g/t gold (0.86 % CuEq*), including
- 476m @ 0.63 % copper and 0.65 g/t gold (1.14 % CuEq), including
- 222m @ 0.83 % copper and 1.08 g/t gold (1.68 % CuEq).
- The intersections achieved in Hole 14 increase the average width of
the Alpala Central Deposit to 300m and show the deposit continues to
remain open to the east and north-east.
- Drill hole CSD-16-015R2 ("Hole 15R2") continues from the
Hole 15 drill site, and is at a current depth of 724.9m in mineralized
porphyry. Hole 15R2 targets extensions of the Alpala deposit to the
north, and at depth, some 100m north of the deeper high-grade zone
intersected in CSD-15-009 ("Hole 9)", which returned 420m @ 1.00 %
copper and 1.34 g/t gold (2.06% CuEq).
- Drill hole CSD-16-016 ("Hole 16") was completed on 21
March 2016 at a total depth of 1661.1m, extending the Alpala deposit by
at least 120m to the south-east in the direction of significant
magnetite/hematite alteration at surface at Hematite Hill. The
intersections achieved in Hole 16 indicate the deposit continues to be
open to the south-east and increases the known strike extent of copper
and gold mineralization along the greater Alpala trend to over 650m.
- Hole 16 intersected some 700m of intense multidirectional
quartz-magnetite-copper sulphide veining from 548m to 1248m. Assay
results from 764m remain pending, and are expected to extend the
previously reported open-ended intersection of 216m @ 0.94 % Copper and
1.26g/t Gold from 548m (1.96% CuEq, see NR 16-04 dated March 4, 2016).
- Drill hole CSD-16-017 ("Hole 17") will be drilled from the same drill
site as Hole 16 and is being positioned to drill towards azimuth
233 at a declination of -74. Hole 17 will test up-dip
extensions of strong copper and gold mineralization intersected in
Holes CSD-13-005 and CSD-15-012 ("Hole 5" and "Hole 12").
- Negotiations for an additional drilling contractor are being
finalized.
* Copper Equivalent (CuEq) is calculated using the following equation:
Cu Eq. = Cu% + (Au g/t x 0.79), using a copper price of $2.25/pound and
gold price of $1225/oz and 100% recovery of metals.
All reported intervals referred to in this news release are core
lengths. At present the true thicknesses of the Hole 14-16
intersections are uncertain due to the early stage of drilling.

DETAILED INFORMATION:
Cascabel Project
The Cascabel Project is located within the northern portion of the
Andean copper belt, renowned as the host of almost half of the World's
copper production, and numerous Tier 1 global copper resource assets.
Cascabel boasts numerous large porphyry copper-gold targets within a
cluster of prospective porphyries in a relatively unexplored section of
the northern oxidized and gold rich Andean copper belt (refer Figure 1
Regional Setting).
Cascabel presents numerous logistic advantages which augment its
potential and known high copper-gold grades. The project is located on
a sealed multi-lane national highway at a low elevation with abundant
water, labour, hydroelectric power, and a short 80km distance to a
Pacific deep water port site at San Lorenzo and 150kms to an
established deep water port at Esmeraldas (refer Figure 2 Location
Map).
A total of 15 drill holes have been completed over the Alpala trend to
date for a total of 21,100m. The geometry of the Alpala Deposit remains
open in virtually all directions (refer Figure 3 Alpala Drilling
Program). Hole 16 has been completed at a depth of 1,661.5m, and Hole
15RD2 is continuing at a depth of 724.9m.
Drilling at the Alpala Deposit is focused on extending the known body
of copper and gold mineralization at 100m centres, towards definition
of a maiden resource. A number of preliminary copper interpolants have
been created, and are constrained by the geological model at Alpala
(refer Figure 4 Copper Interpolants).
SolGold and Cornerstone's understanding of the deposit grows with each
drill hole, and a three dimensional geological model has been developed
using LeapfrogTM modelling software and is consistently updated with
new drill data. Recent work on intrusive phases and geological markers
at Alpala Central provide insight into the geometry and of copper and
gold mineralization and the potential source intrusions (refer Figure 5
Alpala Geological Model). Readers are cautioned that the three
dimensional geological model and the potential quantity and grade of
any resource at Cascabel is currently conceptual in nature, there has
been insufficient exploration to define a mineral resource and it is
uncertain if further exploration will result in the Alpala target being
delineated as a mineral resource.
Hole 14
Hole 14 at Alpala tested northeastern extensions of the Alpala Central
deposit. The drill intersections achieved in Hole 14 increase the width
of the Alpala deposit to an average of 300m.
Hole 14 intersected intense porphyry style stockwork copper and gold
mineralization from within Diorite and Quartz Diorite intrusions from
669.0m to 1176.0m (refer Figure 6 Cross-Section).
Final assay results from CSD-15-014 ("Hole 14") returned following
intersections:
- 768m @ 0.50 % copper and 0.45 g/t gold from 628m (0.86% CuEq),
including:
- 476m @ 0.63 % copper and 0.65 g/t gold from 808m (1.14% CuEq),
including
- 222m @ 0.83 % copper and 1.08 g/t gold from 958m (1.68% CuEq).
Hole 15R2
Drill hole CSD-16-15R2 ("Hole 15R2") continues from the
Hole 15 drill site, and is at a current depth of 724.9m. Hole 15R2
targets extensions of the Alpala deposit to the north, the north-east
and at depth, some 100m north of the lower high-grade zone intersected
in CSD-15-009 ("Hole 9)", which returned a high grade intercept of 420m
@ 1.00 % copper and 1.34 g/t gold.
Hole 16
Drill hole CSD-16-016 ("Hole 16") was completed on 21 March
2016 at a total depth of 1661.1m, successfully extending the Alpala
deposit by 120m to the southeast in the direction of significant
magnetite/hematite alteration at surface at Hematite Hill. The
intersections achieved in Hole 16 show the deposit continues to be open
to the south-east and increases the known strike extent of copper and
gold mineralization along the greater Alpala trend to over 650m.
Hole 16 intersected some 700m of intense multidirectional
quartz-magnetite-copper sulphide veining from 548m to 1248m. Assay
results from 764m remain pending, and are expected to extend the
previously reported open-ended intersection of 216m @ 0.94 % copper and
1.26g/t gold from 548m.
These results are expected in the coming month.
Hole 17
Drill hole CSD-16-017 ("Hole 17") will be drilled from the same drill
site as Hole 16 and is being positioned to drill towards an azimuth of
233 degrees at an inclination of -74 degrees to a planned depth of
1300m. Hole 17 will test up-dip extensions of strong copper and gold
mineralization intersected in Holes CSD-13-005 and CSD-15-012 ("Hole 5"
and "Hole 12"), both of which returned high grade intersections of over
1000m grading above 1% copper equivalent.
This up-dip target zone is expected to link the deeper mineralization
intersected in Holes 5 and 12 with that intersected in CSD-13-001
("Hole 1"), which returned 100m @ 0.65 % copper and 1.00g/t gold from
222m. The intense porphyry style stockwork copper and gold
mineralization intersected in Hole 1 lies close to surface where
rock-saw channel sampling in Alpala Creek demonstrated broad zones of
copper and gold mineralization in trenches TR05, and TR56A, which
returned 33.3m @ 0.65 % copper and 1.02g/t gold, and 53.9m @ 0.32 %
copper and 1.38 g/t gold respectively.
Current Alpala Dimensions
The Central Alpala deposit now extends over 450m in length, 300m in
width and 700m vertically, in a broader Alpala trend of 650m in length,
300m in width and 1800m vertically.
About Cascabel:
SolGold Plc owns 85% of the equity of Exploraciones Novomining S.A.
("ENSA"), an Ecuadorean company that holds 100% of the Cascabel
concession in northern Ecuador. Cornerstone owns the remaining 15% of
ENSA, which also holds the rights to the La Encrucijada gold-silver
project. SolGold is funding 100% of the exploration at Cascabel and is
the operator of the project. Cornerstone's 15% interest is financed
through completion of a feasibility study.
Cascabel 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 inferred resource of 982 million tons at
0.89% Cu Junin copper project (0.4% Cu cut-off grade; Micon
International Co. Ltd. Technical Report for Ascendant Exploration SA,
August 20, 2004, pages 28 & 29). Mineralization identified at the Junin
copper project is not necessarily indicative of the mineralization on
the Cascabel Property.
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 for Cornerstone and has reviewed and approved the information
contained in this news release.
Logging, sampling and assaying
Holes referred to in this release were or are being drilled using HTW,
NTW, NQ and BQ core sizes (respectively 7.1, 5.6, 4.8 and 3.7 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 the ENSA core logging facility, and half of the core is
delivered by ENSA employees for preparation at ALS Minerals
Laboratories (ALS) sample preparation facility in Quito. Core samples
are prepared crushing to 70% passing 2 mm (10 mesh), splitting 250 g
and pulverizing to 85% passing 75 microns (200 mesh) (ALS code CRU-31,
SPL21 and PUL-32). Prepared samples are then shipped to ALS in Lima,
Peru where samples are assayed for a multi-element suite (ALS code
ME-ICP61, 1g split, 4-acid digestion, ICP-AES finish). Over limit
results for Ag (> 100 g/t) and Cu, (> 1%) are systematically re-assayed
(ALS code Ag-AA62, 4-acid digestion, AAS finish). Gold is assayed using
a 30 g split, Fire Assay (FA) and AA finish (ALS code Au-AA23).
Drill hole intercepts are calculated using a data aggregation method,
defined by copper equivalent cut-off grades and reported with with up
to 10m internal dilution, excluding bridging to a single sample.
Quality assurance / Quality control (QA/QC)
The ALS Laboratory is a qualified assayer that performs and makes
available internal assaying controls. Duplicates, certified blanks and
standards are systematically used (1 control sample every 15-20
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.
Plans:
SolGold has announced it is planning a resource statement at Alpala,
the most advanced target at Cascabel, during 2016, in addition to drill
testing the other key targets at Aguinaga, Trivino, Alpala NW, Hematite
Hill, Alpala SE, Cristal, Tandayama America and Chinambicito within the
Cascabel concession. By the end of 2016 SolGold has reported it is
planning further metallurgical testing, and completion of early stage
mine and plant design and a scoping study for an economic development
at Cascabel. SolGold is investigating both high tonnage / low grade
open cut and high grade / low tonnage underground developments as a
block caving operation.
Readers are cautioned that the potential quantity and grade of any
resource at Cascabel is currently conceptual in nature, there has been
insufficient exploration to define a mineral resource and it is
uncertain if further exploration will result in the Alpala target being
delineated as a mineral resource.
