| ||Mount Pearl, NL, Canada: Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) announces the following project update for the Stage 2 drilling program at the Alpala prospect within the Company's Cascabel copper-gold porphyry joint venture exploration project in northern Ecuador.|
- Drill hole CSD-14-007 ("Hole 7") has intersected visible copper sulphide mineralization over 710.60m, commencing from 540.70m and extending to the current depth of 1251.30m, and increasing in broad tandem with modelled magnetic intensity (see Figure 1).
- Recently updated magnetic model is increasingly verified as an excellent tool to map the lateral extent of mineralization in the vicinity of holes 5 and 7.
- Further correlation between magnetite in Hole 7 drill core and modeled magnetic susceptibility reinforces the prospectivity of the Northwest and Southeast targets that are magnetically contiguous with the Central zone.
- Drilling at Hole 7 has encountered abundant chalcopyrite, and the high Cu tenor mineral bornite, in intensely potassic-altered diorite.
- Target location of Hole 8 currently being refined.
All reported intervals referred to in this news release are core lengths. At present the true thicknesses are uncertain due to the early stage of drilling.

Hole 7 Progress
Hole 7 is presently at a depth of 1251.30 metres. Mineralization that is currently being encountered in the hole comprises disseminated, stringer and vein-controlled, coarse grained chalcopyrite and disseminated bornite hosted by a strongly potassic-altered diorite intrusion (see photographs in link above).
The last 49.80 metre interval (to 1251.30m) of drill core is characterized by a marked step-up in quartz vein density, from an average of 5 quartz veins per metre between 780.3m and 1201.5m, to 17 quartz veins per metre between 1201.5m and 1251.30m.
A highly encouraging feature of the strongly mineralized zone that is currently being intersected in Hole 7 is the high abundance of associated hydrothermal magnetite, the magnetic mineral that is the source of the modeled magnetic anomaly in the Central Zone at Alpala. Thus the extensive modeled magnetic anomaly and its down-dip extension to the southwest (Figure 1), and its northwest and southeast extension shown in Figure 2, are robust targets for defining extensions to the mineralization already discovered in Holes 5 and 7.
Hole 7 will continue to drill into the modelled magnetic anomaly that coincides with the mineralized potassic alteration zone.
SolGold Plc owns 85% of the equity of Exploraciones Novomining S.A. ("ENSA"), an Ecuadorean registered 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 with Cornerstone Ecuador S.A. providing some exploration and administrative services. 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. (Mineralization identified at the Cu Junin copper project is not necessarily indicative of the mineralization on the Cascabel Property).
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 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 and NQ core sizes (respectively 7.1, 5.6 and 4.8 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.
