Cornerstone Announces Partial Assays From Hole 13 at Alpala NW Target at Cascabel Project, Ecuador

Known Strike Length of Cu and Au Mineralization Extended to Greater Than 600m Along Greater Alpala Trend

MOUNT PEARL, NEWFOUNDLAND AND LABRADOR--(Marketwired - Dec. 10, 2015) - 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. SolGold Plc is funding 100% of the exploration at Cascabel and is the operator of the project.

HIGHLIGHTS:

  • First batch of assay results in CSD-15-013 ("Hole 13") return an open ended intersection of 376m @ 0.52% copper and 0.25 g/t gold from 926m to 1302m.
  • Confirmation of copper-gold mineralization at Alpala Northwest extends the known strike length of the greater Alpala porphyry system to over 600m.

All reported intervals referred to in this news release are core lengths. At present the true thicknesses of Hole 13 intersections are uncertain due to the early stage of drilling.

FURTHER INFORMATION:

Hole 13 initial batch of assay results, from 926m to 1302m, have returned an open ended interval of 376m @ 0.52% Cu, and 0.25 g/t Au, including two higher grade intervals as shown in Table 1. Remaining assays are expected before the end of the year.

The intersections achieved in Hole 13, increase the known strike extent of copper and gold mineralization along the greater Alpala trend to over 600m (Figure 1). Significant portions of the Alpala porphyry system remain untested and mineralization remains open in all directions.

Zones of high copper / zinc values in soil samples indicate higher temperatures of mineralization and suggest that there are several untested porphyry centres within the greater Alpala area (Figure 2). Ongoing field programs involving the clearing of outcrop and trenching with follow up geological mapping and rock saw channel sampling in these areas, particularly a 200m zone between Holes 13 and 11.

Detailed drill section and level plan interpretations are ongoing and the continual update of geology models, B-vein abundance models, and copper grade models show the emerging geometry of the copper and gold system at Alpala Central and Alpala Northwest (Figures 3 and 4).

Drill holes 14 and 15 are currently under way. Hole 14 is currently at 1320m, and Hole 15 is currently at 706m depth. Both holes have intersected visible porphyry style stock work veining.

An aggressive drilling program is planned for the coming year in order to test the numerous targets being developed at Alpala, Aguinaga, and the recently defined Trivino.

About Cascabel:

SolGold Plc owns 85% of the equity of Exploraciones Novomining S.A. ("ENSA"), an Ecuadorean 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. 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 cut-off 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 (RQDs), 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 the ENSA core logging facility, and half of the core is delivered by ENSA employees for preparation at ALS Minerals Laboratories (ALS) sample preparation facility in Quito. Core samples are prepared crushing to 70% passing 2 mm (10 mesh), splitting 250 g and pulverizing to 85% passing 75 microns (200 mesh) (ALS code CRU-31, SPL21 and PUL-32). Prepared samples are then shipped to ALS in Lima, Peru where samples are assayed for a multi-element suite (ALS code ME-ICP61, 1g split, 4-acid digestion, ICP-AES finish). Over limit results for Ag (> 100 g/t) and Cu, (> 1%) are systematically re-assayed (ALS code Ag-AA62, 4-acid digestion, AAS finish). Gold is assayed using a 30 g split, Fire Assay (FA) and AA finish (ALS code Au-AA23).

Quality assurance / Quality control (QA/QC)

The ALS Laboratory is a qualified assayer that performs and makes available internal assaying controls. Duplicates, certified blanks and standards are systematically used (1 control sample every 15-20 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.

Plans:

SolGold has announced it is planning a resource statement at Alpala, the most advanced target at Cascabel, during 2016, in addition to drill testing the other key targets at Aguinaga, Tandayama America and Chinambicito in the Cascabel concession. By the end of 2016 SolGold has reported it is planning further metallurgical testing, and completion of early stage mine and plant design and a scoping study for an economic development at Cascabel. SolGold is investigating both high tonnage / low grade open cut and high grade / low tonnage underground developments as a block caving operation.
