16-21 - Cascabel Exploration Update - Hole 18 Intersecting Copper Mineralization - 3 Rigs Drilling at Alpala Deposit

  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.

  • Drill Hole CSD-16-018 ("Hole 18"), is intersecting visible copper mineralization from 903.9m depth to current depth 1304.5m. Intensity of veining and copper mineralization is increasing with depth, as drilling continues towards a planned depth of 2300m into the rich lower portions of the Alpala Central deposit.
  • Intense veining up to 45%.
  • Drill Hole CSD-16-019 ("Hole 19"), is at a current depth of 108.8m, targeting extensions of the upper portions of the Alpala deposit above Hole 16.
  • Drill Hole CSD-16-020R ("Hole 20R"), is at a current depth of 239.5m, and will act as the parent hole of at least 7 directional drilling "daughter" holes, testing up to 650m below the thickest, richest part of the Alpala deposit.
  • Access road to Alpala completed with vehicle access to Alpala Base Camp now fully operational and three drilling rigs operational.

The Cascabel Project is located on the gold-rich northern section of the prolific Andean Copper belt renowned as the production base for nearly half of the world's copper, (Figure 1). The project area hosts mineralization of Eocene age, the same age as numerous Tier 1 deposits along the Andean Copper Belt in Chile and Peru to the south. The project base is located at Rocafuerte, in northwestern Ecuador just west of the City of Ibarra, approximately 3 hours drive north of Quito and close to water, power supply and Pacific Ports (Figure 2). SolGold holds an 85% interest in ENSA (Exploraciones Novomining S.A.) which holds the Cascabel concession.

Fourteen different targets have been defined at Cascabel and only one of these, the Alpala deposit has been drilled to date. The deposit at Alpala continues to grow with each new drill hole. Drilling has focussed on defining the geometry of the Alpala deposit, which is open in all directions. Over 25,342m of drilling has been completed to date (Figure 3).

Hole 18 is currently at a depth of 1304.5m within veined and mineralized quartz diorite porphyry. Intensity of veining and copper mineralization is increasing with depth with up to 45% veining observed recently at 1250m. Hole 18 continues towards a planned depth of 2300m into the untested lower projections of the Alpala Central deposit down plunge from drill holes 5, 8, 12 and 16.

Examples of drill core intersected to date in Hole 18 show intense porphyry style veining and associated visual copper mineralization (Figures 4 and 5). Traditionally copper mineralization at Alpala has been accompanied by gold on an approximate 1g/t Au to 1% Cu ratio which increases to 2:1 at high copper grades.

Hole 19 is at a current depth of 108.8m, and is being drilled to extend the upper portions of the deposit above Hole 16. Hole 19 is being drilled from the same site as Hole 17, and is targeting upper extensions of strong copper and gold mineralization intersected in Hole 16, which returned a high grade intersection of 1145.6m grading 0.63 % copper and 0.78 g/t gold from 430m, including a high-grade core of 373.6m grading 1% copper and 1.34 g/t gold.

Hole 20R, is at a current depth of 299.5m, and will act as the parent hole for up to 7 directional drilling "daughter" holes, testing up to 650m below the thickest, richest part of the Alpala Deposit (Figure 6). Both drill holes 19 & 20R are still above the expected top of the deposit in that position.

The original Hole 20 was replaced with Hole 20R at 160m and the completion of the Alpala to Carmen Road as far as the Alpala Camp now enables SolGold to operate efficiently having overcome operational difficulties in delay in regards to completion of the road.

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. 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 northwestern Ecuador in an under-explored northern section of the Andean Copper Belt, 60 km northeast of the undeveloped inferred resource of 982 million tons at 0.89% Cu Llurimaga (formerly 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 Llurimaga copper project is not necessarily indicative of the mineralization on the Cascabel Property.

To date SolGold has completed geological mapping and soil sampling over 25 km2, along with and an additional 9km2 of Induced Polarisation and 14km2 Magnetotelluric "Orion" surveys over the Alpala cluster and Aguinaga targets. SolGold has completed over 25,000m of drilling and expended over USD 35M on the program, corporate costs and investments into Cornerstone. Intense diamond drilling is planned for the next 12 months with multiple drill rigs.

The Alpala deposit is open at depth and in the upper extensions, as well as to the north, north-east, south-east and south-west. The mineralized zone at Alpala and Moran is closely modelled by magnetic signatures and currently encompasses over 10Bt of magnetic rock expected to be mineralized with copper and gold.

SolGold is focussing on extending the dimensions of Alpala before completing a resource statement and drill testing the other key targets within the Cascabel concession at Alpala Southeast, Aguinaga, Trivino, Moran, Alpala Northwest, Hematite Hill, Cristal, Parambas, Carmen, Tandayama-America and Chinambicito. SolGold is planning further metallurgical testing and completion of a conceptual early stage mine and plant design and a scoping study for an economic development at Cascabel. SolGold is investigating both high tonnage / low-medium grade open cut and underground block caving operations, and a high grade / low tonnage underground development.

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 LAC y Asociados ISO 9001-2008 certified sample preparation facility in Cuenca. Core samples are prepared crushing to 70% passing 2 mm (10 mesh), splitting 250 g and pulverizing to 85% passing 75 microns (200 mesh) (MSA code PRP-910). Prepared samples are then shipped to MS Analytical Services (MSA), an ISO 9001-2008 laboratory in Langley, BC, Canada where samples are assayed for a multi-element suite (MSA code IMS-230, 0.2g split, 4-acid digestion, ICP-AES/MS finish). Over limit results for Cu (>1%) are systematically re-assayed (MSA code ICF-6Cu, 0.2 g, 4-acid digestion, ICP-AES finish). Gold is assayed using a 30 g split, Fire Assay (FA) and AAS finish (MSA code FAS 111). Over limit results for Au (>10 g/t) are systematically re-assayed (MSA code FAS-415, FA, 30g., gravimetric finish).

Drill hole intercepts from the Cascabel Property are calculated using a data aggregation method, defined by copper equivalent cut-off grades and reported with up to 10m internal dilution, excluding bridging to a single sample. Copper equivalent grades are calculated using a gold conversion factor of 0.89, determined using copper price of US$2.20/pound and gold price of US$1350/ounce. Copper equivalent calculation assumes 100% recoveries of copper and gold.

All reported drill core intervals from the Cascabel Property are core lengths, unless otherwise indicated. At present the true thicknesses of all of the holes has not been calculated by SolGold. Low-grade intersections, where applicable, are expressed as average true widths (utilizing the "B-vein > 0.5%" shell orientations). High-grade intersections are better constrained for holes 1, 5, 8 and 9, and these intersections are also expressed as average true widths (utilizing the "B-veins > 20%" shell orientations).

Quality assurance / Quality control (QA/QC)
The MSA Analytical 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.
