Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) announces that assay results have been received for the lower portion of drill hole CSD-13-002 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 the entire drill hole CSD-13-002 yield the following copper-gold intersections:
- 18m @ 0.33% copper, 0.41 g/t gold (from 6m);
- 292m @ 0.37% copper, 0.30 g/t gold (from 126m); including 42m @ 0.50% copper, 0.68 g/t gold (from 184m).
- Copper-gold mineralization encountered to date is interpreted to lie within a high-level structural zone that taps a larger porphyry copper-gold system at depth.
- Higher grade intervals included:
- 10m @ 0.91% Cu, 0.41 g/t Au (from 130m)
- 2m @ 2.58% Cu, 0.81 g/t Au (from 132m)
- Hole CSD-13-004 terminated at a depth of 318.51m due to poor ground conditions.
- Hole CSD-13-005 will test the porphyry target below Holes 1 and 2 and is due to commence within the next few days.
- Assays for Hole CSD-13-003 are anticipated in 2 weeks.
Drill Hole CSD-13-002 Assay Results
A second batch of assay results has been received for drill hole CSD-13-002. The hole was terminated at 547.42m depth in mineralization due to hole deviation caused by faulting in the deeper part of the hole and associated drilling difficulties.
The copper and gold intersections for the entire drill hole are outlined in Table 1 below. The new extended intersection further confirms and expands the known distribution of copper-gold mineralization below the zone of outcropping stock-work vein mineralization in Alpala Creek. Figure 3 shows a cross-section of gold and copper intersections in holes CSD-13-001 and CSD-13-002. Two main intersections were encountered in drill hole CSD-13-002:
- A shallow intersection of 18m length grading 0.33% Cu, 0.41 g/t Au (from 6m depth).
- A deeper intersection of 292m length grading 0.37% Cu, 0.30 g/t Au (from 126m depth).
The extensive mineralization within the hole (292m @ 0.37% copper and 0.30 g/t gold) is particularly encouraging, and it laterally expands the extent of mineralization on cross-section at Alpala Creek (refer Figure 3).

Drill Holes CSD-13-003, CSD-13-004 and CSD-13-005
Drill Hole CSD-13-003 terminated at 751.33m (see separate NR dated 4 November 2013). Assay results are expected in 2 weeks.
Drill Hole CSD-13-004 was terminated at a depth of 318.51m due to poor ground conditions. CSD-13-004 was sited to test an area 300 metres vertically below the lower mineralized interval in Hole CSD-13-001 (Figure 3) but the hole was terminated at 318.51m due to poor ground conditions. A re-designed hole, CSD-13-005, will be collared at the same location as CSD-13-001 and drilled at a steeper angle of -85 degrees to test for the continuation of the high grade copper-gold mineralization intersected in the lower section of CSD-13-001 (Figure 2).
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."

Logging, sampling and assaying
Hole CSD 13-002 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.
