Cornerstone Capital Resources Inc.: Cascabel Exploration Update; Further Copper Sulphides in Hole 9 Extends Intersection to Over 1 Kilometre

MOUNT PEARL, NEWFOUNDLAND--(Marketwired - Dec. 9, 2014) - Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSX VENTURE:CGP)(OTCBB:CTNXF)(FRANKFURT:GWN)(BERLIN:GWN) 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.

HIGHLIGHTS:

  • Copper sulphide mineralization intersected from 1168.28m to 1455.64m, over an interval of 287.36m and continuing in Hole CSD-14-009 ("Hole 9");
  • Copper sulphide mineralization intersected over a 1 kilometre downhole interval from 452.45m to 1455.64m depth (current hole depth);
  • Copper sulphides including appearance of bornite continuing at current hole depth;
  • Copper mineralization and quartz veining now extended below and lateral to the high grade Hole 5 intersection;
  • Assays for interval 810m to 1324m expected in the latter half of December; and
  • High grade copper-gold resource targeted at Alpala.

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.

FURTHER INFORMATION

Hole 9

Hole 9 is located 120m north of the Hole 5 drill pad and is being drilled with an 85 degree inclination towards 210 degrees UTM (Universal Transverse Mercator) (Figures 1 and 2). Hole 9 was sited to test for the northwest extension of the high-grade copper and gold mineralization intersected in Hole 5 and to test for vertical extension of this high grade mineralization up to 500m below the Hole 5 intersection.

Drilling of Hole 9 commenced on October 28, 2014. On December 7, 2014 the hole was at 1455.64 metres depth and located within the MVI modeled magnetic high.

On December 2, the Company reported a high grade copper and gold intersection from 650m to 810m depth over a 160m interval which graded 0.84% copper ("Cu") and 1.56 g/t gold ("Au") for 1.78% Cu-equivalent. This intersection included a higher grade core of 80m grading 1.32% Cu and 2.72 g/t Au (for 2.95% Cu-equivalent) which is open at depth at 810m. The Company is currently waiting for assays below this interval.

Hole 9 has now intersected a second zone of Cu sulphide mineralization. This second zone commences at 1168.28m depth and continues to the current downhole depth of 1455.64m, over a distance of 287.36m. Copper sulphide mineralization is associated with strong quartz B-vein stockworks, with vein abundances averaging 15-20% across the 287.36m interval, and with estimated vein abundances up to 35% in some intervals. The interval of mineralization shows abundant magnetite and persistent biotite that defines the potassic alteration assemblage. The appearance of the copper rich sulphide mineral bornite in Hole 9 is considered to be an encouraging indicator for proximity to the core of the porphyry mineralized system.

This second interval of mineralization occurs within a quartz diorite intrusive, and is interpreted to be the same intrusive host rock as the high grade intersection in Hole 5. Mineralization continues to be dominated by coarse chalcopyrite within B-veins and overprinting C-veins and as disseminations in the intrusive host rocks. Figure 2 shows a southwest-northeast cross-section through Hole 9 at Alpala.

Hole 9 continues to intersect copper sulphide mineralization at the current depth of 1455.64m.

Copper sulphide mineralization in Hole 9 has now been intersected over a downhole interval of 1003.19m, from 452.45m to the current hole depth of 1455.64m. Mineralization has now also been demonstrated to occur at a relative level ("RL") that is below the base of and 120m laterally north of the Hole 5 intersection which, from 458m to 1346m, comprised 888m grading 0.77% Cu and 0.72 g/t Au (for 1.21% Cu-equivalent) as reported on November 10, 2014. The Company is confident that these results indicate the presence of a mineralized porphyry target at Alpala.

Plates 1-19 show examples of the coarse grained chalcopyrite intersected in 'B-veins' and 'C-veins' from Hole 9 over the downhole interval of 1185.20m to 1452.35m.

About Cascabel

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 (0.4% Cu cutoff grade; Micon International Co. Ltd. Technical Report for Ascendant Exploration SA, August 20, 2004, pages 28 & 29). Mineralization identified at the Junin copper project is not necessarily indicative of the mineralization on the Cascabel Property.

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 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.
