Cornerstone Capital Resources Inc.: Strong Copper-Gold Mineralization Discovered at Surface at Aguinaga Prospect, Cascabel Project, Ecuador
(firmenpresse) - MOUNT PEARL, NEWFOUNDLAND -- (Marketwired) -- 11/03/15 -- 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.

"Apart from the highly prospective Alpala Prospect, there are currently four other target areas within the Cascabel tenement including: Quebrada Tandayama-America, Aguinaga and Quebrada Moran are prospective for copper-gold porphyry deposits and Rio Cachaco is prospective for epithermal gold style mineralization," said Brooke Macdonald, Cornerstone''s CEO.
FURTHER INFORMATION:
After reconnaissance field-work initially located mineralized porphyritic diorite along the northern slope of Aguinaga Hill, subsequent detailed 1:500 scale "Anaconda" style geological and structural mapping has led to the discovery of porphyry stockwork copper-gold mineralization outcropping at surface.
Mineralization is exposed along the upper section of Aguinaga Creek, where classic porphyry style ''B''-type quartz-magnetite-chalcopyrite-bornite stockwork veining occurs within porphyritic diorite (Figure 2).
The outcropping mineralization is accompanied by potassic (biotite) alteration and remains open to the north where creek sediments and dense vegetation limit further surface exposure. Potassic alteration and bornite is highly diagnostic of the core mineralization in a typical porphyry copper-gold system.
Rock-saw channel sampling results over the exposed outcrop returned an open ended intersection of 9.0m (at) 1.01 % Cu, and 0.79 g/t Au (Table 1, Figure 3)

The Aguinaga prospect lies on a prominent topographic high (1615masl) about 3km south of Rocafuerte site office and 1.3km to the northeast of the Alpala prospect which is currently being drilled. SolGold geologists believe the Aguinaga target is extremely compelling for four key reasons:
SolGold is currently conducting field mapping, rock saw trenching, and infill soil-sampling programs, along with spectral analysis of soils to determine hydrothermal alteration assemblages.
SolGold expects to bring the prospect to drill-ready status over the coming quarter.
Plans:
Solgold is planning a resource statement at Alpala, the most advanced target at Cascabel, by mid 2016, in addition to drill testing the other key targets at Aguinaga, Tandayama America and Chinambicito on the Cascabel concession. By the end of 2016 SolGold 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 development as a block caving operation.
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
Rock samples are delivered by ENSA employees for preparation at ALS Minerals Laboratories (ALS) sample preparation facility in Quito. 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 (greater than 100 g/t) and Cu, (greater than 1%) are systematically re-assayed (ALS code Ag-AA62 and Cu-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 the QA/QC program. Rejects, a 100 g pulp for each rock and core sample and the remaining half-core are stored for future use and controls.
