13-23 - Cornerstone Drills 100m of 0.50% Copper and 1 g/t Gold at Cascabel Project in Ecuador
| ||Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) announces that preliminary assay results have been received for Drill Hole CSD-13-001 at the Alpala prospect within the Cascabel Project, the Company's copper-gold porphyry exploration project in northern Ecuador (refer Figure 1). |
All figures and table related to this news release can be seen at http://www.cornerstoneresources.com/i/pdf/NR13-23Figures.pdf.
- Preliminary assay results indicate copper-gold mineralization in Drill Hole CSD-13-001 over 2 zones:
- 104m @ 0.37% copper and 0.38 g/t gold from 16 to 120m, and;
- 100m @ 0.50% copper and 1 g/t gold from 222 to 322m (including 58m @ 0.70 Cu and 1.67 g/t Au and 16m @ >1% Cu and 3.25 g/t Au).
- High grade zones over 1% copper (principally 232m to 248m) to be re-assayed at higher copper cut-off technique.
- Mineralization styles indicative of potentially significant copper-gold porphyry system.
- Drill Hole CSD-13-002 assays awaited.
- Drill Hole CSD-13-003 underway targeted to intersect interpreted magnetic core of the porphyry system.
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 tonnes at 0.89% Cu Junin copper project.
Drill Hole 1 -- Preliminary Assay Results
The preliminary assay results received and as outlined in Table 1 below confirm the visually encouraging mineralization encountered and reported by Cornerstone September 11, 2013 in Drill Hole CSD-13-001 at Alpala, Cascabel, which terminated at 353.56m. Figure 3 shows copper and gold values down hole together with the principal intersections while Figure 4 shows a cross-section of gold and copper intersections.
Eleven (11) 2m samples require re-assaying for copper, using a less sensitive assay technique, as these results were all greater than 1% copper, the maximum value for the preliminary assay technique employed. These samples are located between the following intervals:
The preliminary assay results for Drill Hole 1 support the Cornerstone and SolGold assessment that Drill Holes CSD-13-001 and CSD-13-002 are located on the margins and associated with alteration zones above and northwest of the presently interpreted core of the porphyry system, as indicated by the 3D magnetic interpretation and alteration mineral spectral datasets.
- 52m to 54m
- 226m to 228m
- 232m to 248m
- 262m to 264m
Cornerstone considers the intersections encountered in Hole CSD-13-001 to be robust. The continuity of copper mineralization is particularly encouraging. Updated results will be announced as soon as the final assay results are received.

Assay results for Drill Hole CSD-13-002 are still awaited. Drill Hole CSD-13-003 is currently underway, and was at a depth of 183m on October 9, 2013.

Logging, sampling and assaying
Hole CSD 13-001 was drilled using HTW core size (7.1 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.
