Cornerstone Capital Resources Inc.: 14 Porphyry Targets Identified to Date at Cascabel Project, Ecuador

OTTAWA, ONTARIO--(Marketwired - July 6, 2016) - 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. SolGold Plc is funding 100% of the exploration at Cascabel and is the operator of the project.

HIGHLIGHTS:

  • 14 porphyry targets generated within the Cascabel concession, 7 of which have been elevated to close to drill ready status
  • Proximity to the growing high-grade Alpala porphyry copper-gold deposit and genetic similarity suggests prospectivity of these satellite targets
  • Magnetic modelling on the greater Moran-Alpala trend reveals similarities to the Hugo Dummet deposit of Oyu Tolgoi, Mongolia

FURTHER INFORMATION:

Recent geological and geochemical field work in conjunction with updated three dimensional MVI magnetic modelling has defined fourteen copper-gold porphyry targets within the Cascabel concession. Proximity to and geologic similarity with the growing Alpala porphyry copper-gold deposit suggests that these satellite targets within the Cascabel project area in Northern Ecuador (Figure 1, Location) could yield similar deposits to Alpala. Recently, modelling has identified coincident magnetic and molybdenum anomalism which is considered to be diagnostic of new targets at Moran, Carmen and Parambas. SolGold has recently reported on its initial investigations at Moran, and is currently commissioning mapping and sampling programs at Carmen and Parambas. As with Moran, the Company aims to define significant areas of surface mineralization at Carmen and Parambas.

The Cascabel Project is located on the gold rich northern section of the prolific Andean Copper belt (Figure 2, Regional Setting).

Seven high priority porphyry centres are now within the Cascabel project, from a total of fourteen porphyry targets inferred to date, including the newly discovered Moran, Carmen and Parambas target areas (Figures 3 and 5, Cascabel Targets).

Revised magnetic modelling, reconciled to downhole magnetic susceptibility readings from drill core, has refined MVI magnetic models so that the models represent a proxy for magnetite-chalcopyrite style porphyry mineralization that exists at Cascabel. Soil geochemistry, molybdenum anomalies and detailed 1:500 scale "Anaconda" style surface geological and structural mapping has resulted in increased confidence in targeting other rich parts of the wider porphyry systems within the Cascabel concession.

The northwesterly trend of the Moran-Alpala MVI magnetic anomaly reveals a geometry which is similar to the porphyry system at Hugo Dummet, in Oyu Tolgoi, Mongolia (Figure 4, Long-section of the Moran-Alpala Wider Target Zone).

The quality of this corridor as a high priority target is supported by contiguous datasets, including MVI magnetics, soil geochemistry, induced polarization resistivity, and spectrometry to assess the diagnostic clays mineralogy in soils which are typically consistent with sulphide bearing disseminated and/or stockwork style mineralization peripheral to, and above, a mineralized porphyry stock (Figures 5, 6 and 7).

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 northwestern Ecuador in an under-explored northern section of the Andean Copper Belt, 60 km northeast of the undeveloped inferred resource of 982 million tons at 0.89% Cu Llurimaga (formerly 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 Llurimaga 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 the ENSA core logging facility, and half of the core is delivered by ENSA employees for preparation at LAC y Asociados ISO 9001-2008 certified sample preparation facility in Cuenca. Core samples are prepared crushing to 70% passing 2 mm (10 mesh), splitting 250 g and pulverizing to 85% passing 75 microns (200 mesh) (MSA code PRP-910). Prepared samples are then shipped to MS Analytical Services (MSA), an ISO 9001-2008 laboratory in Langley, BC, Canada where samples are assayed for a multi-element suite (MSA code IMS-230, 0.2g split, 4-acid digestion, ICP-AES/MS finish). Over limit results for Cu (>1%) are systematically re-assayed (MSA code ICF-6Cu, 0.2 g, 4-acid digestion, ICP-AES finish). Gold is assayed using a 30 g split, Fire Assay (FA) and AAS finish (MSA code FAS 111). Over limit results for Au (>10 g/t) are systematically re-assayed (MSA code FAS-415, FA, 30g., gravimetric finish).

Drill hole intercepts from the Cascabel Property are calculated using a data aggregation method, defined by copper equivalent cut-off grades and reported with up to 10m internal dilution, excluding bridging to a single sample. Copper equivalent grades are calculated using a gold conversion factor of 0.89, determined using copper price of US$2.20/pound and gold price of US$1350/ounce.

All reported drill core intervals from the Cascabel Property are core lengths, unless otherwise indicated. At present the true thicknesses of all of the holes has not been calculated by SolGold. Low-grade intersections, where applicable, are expressed as average true widths (utilizing the "B-vein > 0.5%" shell orientations). High-grade intersections are better constrained for holes 1, 5, 8 and 9, and these intersections are also expressed as average true widths (utilizing the "B-veins > 20%" shell orientations).

Quality assurance / Quality control (QA/QC)

The MSA Analytical 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, Trivino, Alpala NW, Hematite Hill, Alpala SE, Cristal, Tandayama America, Moran, and Chinambicito within 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 (which may or may not be the approximate equivalent of a preliminary economic assessment as defined under National Instrument 43-101) for an economic development at Cascabel. SolGold has reported it is investigating both high tonnage / low grade open cut and high grade / low tonnage underground developments as a block caving operation.
