Cornerstone Capital Resources Inc.: Final IP Interpretations and Outcropping Copper Mineralization Support Robust Porphyry Target at Southeast Alpala

MOUNT PEARL, NEWFOUNDLAND--(Marketwired - Dec 4, 2014) - Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSX VENTURE:CGP)(FRANKFURT:GWN)(BERLIN:GWN)(OTCBB:CTNXF) 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:

• Final electrical geophysical models (resistivity and chargeability) for Orion 3D Induced Polarization ("3DIP") and magnetotelluric ("MT") surveys strongly validate target T2 at Southeast Alpala;
  
  
• Target T2 lies in the hanging wall to the Alpala Structural Zone, and comprises deep magnetic anomalies with strong electrical conductive responses around the upper parts of the anomaly;
  
  
• The core of the T2 target has dimensions of 600m by 300m, within a broader target area of 800m by 600m;
  
  
• Mapping at the T2 target at Southeast Alpala discovers chalcopyrite, bornite and chalcocite copper sulphide mineralization in lithocap outcrops at Quebrada Malte and Rio Cristal;
  
  
• IP data at the T2 target are consistent with magnetic vector inversion ("MVI") and geological datasets, indicating both magnetic and IP models are robust; and
  
  
• Market update on the Aguinaga porphyry target will be made as soon as possible.
  
  

Cornerstone's CEO, Brooke Macdonald, said: "We are pleased to see how well the multiple parts of the Alpala mineralization model are gradually fitting together. Drilling at the existing targets validate the Orion IP and MT data and the new data for the T2 target in the southeast portion of the Alpala target define new and very sizeable areas to be tested, enhancing the probability to discover new mineralization. Our knowledge and confidence to outline a significant copper-gold resource at Cascabel are increasing."

FURTHER INFORMATION

Final Orion 3DIP chargeability models and conductivity models were received on November 25^th from Quantec Geoscience for both the Alpala and the Aguinaga surveys.

Alpala Targets following Interpretation of Orion 3DIP and MT Data

High priority targets T1 and T2 at Alpala, previously referred to as the 'North West Target' and 'South East Target' in prior news releases, are located beneath the northwest and southeast lithocap lobes respectively (Figure 1). Target T3 lies due north of Target T2 at Southeast Alpala. Target T4 lies north of Target T1 and covers likely deeper extensions of porphyry quartz stockwork veins that are mapped at Quebrada Moran (Figure 1).

First-pass integration of the Orion 3DIP geophysical data with surface soil geochemistry, alteration, the current mineralization model at Central Alpala and recent surface mapping has validated and refined existing targets, and defined new targets (Figure 1).

Target T2 - Southeast Alpala

The T2 target at Southeast Alpala coincides with a deep magnetic ridge below the Southeast Alpala lithocap ("T2 Magnetic Ridge"; Figure 3). This north-northeast (N10E) trending magnetic ridge lies at around 600m depth and is capped by zones of magnetite destructive alteration above 1100m above sea level (asl or RL, Figure 5). A deep magnetic anomaly overlain by magnetite-destructive alteration - that reflects a shallow hydrothermal system - is common to both the T2 MVI anomaly and the Central and Northwest Alpala MVI anomaly.

Target T2 - MVI Magnetic Dataset

The T2 Magnetic Ridge has dimensions of 800m north-south by 400m east-west and is close to the dimensions of the deep MVI anomaly at Central and Northwest Alpala. The magnetic signature is interpreted to be caused by primary and secondary magnetite along a north-south elongated and fault-controlled magnetic apophyse. The modeled upper surface of the T2 magnetic ridge reveals a knoll near its southern end where it abuts against the Alpala Structural Zone (Figures 2 and 3). The magnetic ridge forms the upper part of an interpreted intrusion that is bound on its west side by the ASZ (Figures 5-7). The ASZ is a key controlling fault for both Targets T1 and T2 (Figure 1).

Target T2 - Orion 3DIP and MT Datasets

The Orion shallow conductivity and chargeability models reveal anomalous zones of conductivity (and chargeability) that cap the T2 magnetic ridge, indicating the presence of sulphides, fracturing and/or clays around this magnetic apophyse (Figure 3, Panel B).

Target T2 - Soil Geochemistry and Alteration Datasets

At surface, north-south zones of arsenic, bismuth, tellurium and antimony enrichment in soil samples (volatile path-finder elements that are enriched above porphyry deposits) overly the magnetic target and appear to be controlled by faults that tap the underlying target porphyry system (Figure 4).

This region of strong pathfinder element geochemical anomalism above and west of the underlying T2 magnetic ridge is associated with the acid-stable minerals kaolinite, dickite and pyrophyllite along north-south topographic lineaments. These alteration minerals form from magmatic fluids that emanate from an underlying porphyry copper-gold system and have ascended along the permeable north-south cross-faults.

Target T2 - Mapping and Discovery of Copper Sulphide Occurrences at Surface

Recent mapping over the T2 target area at the Southeast Alpala lithocap has identified copper sulphide mineral occurrences (chalcopyrite, bornite and chalcocite) at surface in Quebrada Malte (Figure 4). Channel sampling is planned for this area and mapping is being conducted to further refine the target geology at surface.

The Orion 3DIP and MT, MVI magnetic, geochemical and geological data collectively define a robust and high priority porphyry copper-gold target under the Southeast Alpala lithocap.

Further details of the Southeast Alpala target (T2) will be provided following completion of surface mapping that is currently underway in the area.

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.

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.
