Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) announces that drill hole CSD-13-005 at the Alpala prospect within the Cascabel Project at the Company's copper-gold porphyry exploration project in northern Ecuador (refer Figure 1), has returned strong porphyry copper gold results over 845 metres of the hole to date. The results indicate discovery of a large high-grade copper gold porphyry system.|

- Large scale, high-grade porphyry system discovered.
- Drill hole CSD-13-005 was temporarily suspended on December 20, 2013 at 869.68m in strong copper and gold mineralization open at depth pending delivery of additional drilling equipment.
- Final assay results from sample batches 1 and 2 of drill hole CSD-13-005 have returned the following copper-gold intersections:
- 845.68m @ 0.39% Cu & 0.24 g/t Au (from 24m to end of hole).
- Higher grade intervals including:
- 154m @ 0.43% Cu, 0.25 g/t Au (from 244m to 398m);
- 211.68m @ 0.69% Cu, 0.51 g/t Au (from 658m to end of hole)
- Last 91.68m returned 0.90% Cu, 0.79 g/t Au (from 778m to end of hole)
- Copper and gold grades increasing with depth.
- Strong correlation between magnetite, magnetic response and copper mineralisation in CSD-13-005 confirms significance of 4km2 Alpala magnetic complex.
- Drill hole CSD-13-005 expected to resume drilling during week of January 20th with targeted depth of 1500 metres.
Cornerstone's President & CEO, Brooke Macdonald, said: "Assay results from hole CSD 13-005 not only confirm visual examination of significant copper mineralization usually tightly associated with gold reported in December, but also that the proposed exploration and mineralization models work very well, indicating the potential to host large size, gold enriched porphyry copper deposits at Alpala and other target areas on the property. Indications are that we are just entering the higher-grade core of the porphyry system. Exploration results have been excellent from day 1 when we started prospecting work at Cascabel. This is a very good sign. We believe that there are very few countries around the world where geologists can still find significant outcropping porphyry copper-gold mineralization. Ecuador is one of them. This reinforces our commitment to the country, and demonstrates Cornerstone's ability to "deliver the goods" for our partners from early grass-root programs. We have several other 100% owned properties available for joint venture which can be viewed on our web site."
Drill Hole CSD-13-005 Preliminary Assay Results
The location of drill hole CSD-13-005 is illustrated in Figure 2. CSD-13-005 was sited to test beneath holes 1 and 2, which intersected long runs of copper and gold mineralization associated with porphyry copper gold quartz stock-work and sheeted veins. Copper and gold intersections for drill hole CSD-13-005 to a depth of 869.68 metres are listed in Table 1 below. Figure 3 shows a cross-section of copper and gold intersections in holes CSD-13-001 and CSD-13-005.
Two main intersections have been encountered in drill hole CSD-13-005 to date:
A bulked intersection in drill hole CSD-13-005 comprises an 845.68m interval grading 0.39% Cu and 0.24 g/t Au (from 24m depth). Other higher-grade intervals are listed in Table 1.
- A shallow intersection of 396 metres grading 0.32% Cu and 0.17 g/t Au (from 24 m depth).
- A deeper intersection of 433 metres grading 0.47% Cu and 0.31g/t Au (from 436 m depth).
The extensive mineralization within the hole (845.68m grading 0.39% copper and 0.24 g/t gold) is particularly encouraging especially given the strong correlation with magnetite from 680 metres downhole.

Logging, sampling and assaying
Holes referred to in this release were or are being 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.
