16-07 - Cascabel Exploration Update - Mineralization at Surface Discovered South of the Alpala Structural Zone

 Ottawa, ON, Canada: Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-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.


- Porphyry style mineralization discovered on surface 100m south of the surface projection of Alpala Structural Zone (ASZ), defining a new target area, Alpala South.

- 1:500 scale geological mapping progresses and upgrades the Hematite Hill Prospect.

- Detailed geological mapping continues as rock-saw channel sampling begins over both Hematite Hill and Alpala South areas.

Cascabel Project
The Cascabel Project is located within the northern portion of the Andean copper belt (refer Figure 1 Regional Setting), which hosts numerous large porphyry copper-gold targets identified by coincident geophysical and geochemical anomalies that are interpreted as a cluster of prospective porphyries. They occur in a relatively unexplored section of the northern Andean copper belt that produces very oxidized, gold rich porphyry deposits (refer Figure 1 Regional Setting). The project is located on a sealed multi-lane national highway at a low elevation with abundant water, labour, hydroelectric power, and a short 80km distance to a Pacific deep water port site at San Lorenzo and 180kms to an established deep water port at Esmeraldas (refer Figure 2 Location Map).

Field Work Update

Ongoing expansion of 1:500 scale geological mapping and rock-saw channel sampling across the growing Cascabel porphyry field has led to another discovery of porphyry copper-gold mineralization in outcrop, along the northern and southern slopes of the newly discovered Alpala South prospect, which lies 400m due south of Hole 5 at Alpala Central (Figure 3). The extent of outcropping mineralization at Alpala South and Hematite Hill has not yet been defined, as mapping continues over the ridges that separate Alpala Central and Alpala Southeast (Figure 4).

The prospective centres at Alpala South and Hematite Hill occur within an area of elevated magnetic response within part of the complex magnetic signature that occurs over the wider Alpala area, known as the Alpala Magnetic Complex (Figure 5).

These new prospects occur along either side of the south-eastern extension of the surface projection of Alpala Structural Zone ("ASZ"). The ASZ is a deep seated regional north‐west trending structure inferred to be a zone of crustal weakness tapping into copper and gold rich intrusions at Alpala Central.

The presence of a discrete copper / zinc soil anomaly, supports a preserved porphyry centre characterized by higher temperatures of mineralization. This geochemical signature is typical of the metal zonation around many global porphyry copper‐gold deposits. The occurrences of more distinct copper / zinc anomalies further south of Alpala South, and at Alpala Southeast are priority areas for the ongoing reconnaissance field inspection (Figure 6).

The outcrops at Alpala South contain porphyry style quartz - iron oxide veins, the fresh sulphides having been leached from the weathering environment. The veining occurs within volcanic host rocks in a sheeted form, with veins orientated along a WNW trend, and dipping steeply towards the NNE (Figures 7 and 8).

The Alpala South discovery, like the recent finds of outcropping copper and gold mineralization at Aguiñaga and Trivino, highlights the fertility and potential of the broader porphyry copper-gold system at Cascabel. Mineralized surface outcrops such as these that display very high vein density, up to 10% of the total rock mass, and in such close proximity to the vertically extensive high grade copper and gold mineralization discovered at Alpala (see, for example, news release 14-07 dated March 3, 2014 - 1306m grading 0.62% Cu and 0.54 g/t Au), make for certain drill targets.

The discovery of new outcrops around Alpala is becoming increasingly numerous, for example the outcrops at Aguiñaga and Trivino, and detailed 1:500 scale "Anaconda" style surface mapping has now been completed over a surface extent of around 1.1 square kilometres. The frequency of discovery of new mineralized outcrops of porphyry style mineralization at Cascabel suggests the importance of this system as a globally significant discovery.

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 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.


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 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.

Readers are cautioned that the potential quantity and grade of any resource at Cascabel is currently conceptual in nature, there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the Alpala target being delineated as a mineral resource.
