|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.|

The Cascabel Project is located in Northern Ecuador, within the northern portion of the Andean copper belt (Figure 1, Location).
Holes 15R2 and 17
Samples for drill holes CSD-16-015R2 and CSD-16-017 (Holes 15R2 and 17) are currently at the assay laboratory and upon receipt the results will be compiled and announced.
Drill holes 18 and 19 will be sited after consideration of the results of the updated magnetic modeling and the preliminary evaluation of the Moran Prospect (both addressed below). Maintenance and re-tooling of the drill rigs are currently taking place on site.
Field Mapping and Sampling
Activities are continuing in the field with a focus on extensions around the Alpala South, Triviņo, and the Aguiņaga prospects where an infill deep augering program is underway across the copper gold and molybdenum anomalous areas. Results will be released on completion of the program.
Ongoing mapping and sampling activities have identified an additional classically zoned outcropping and copper mineralized porphyry system at the Moran Prospect approximately 1.2 km north of the Alpala North West centre of the Alpala trend at Cascabel (Figures 2 and 3). The prospect is characterised by an outcropping 300 x 300 m (open) zone of variably fractured and mineralized intrusive and volcanic rocks exhibiting >2% multidirectional vein intensity characteristic of strong copper gold mineralization at Alpala. The mineralization at Moran exhibits chalcopyrite (copper sulphide) in quartz and magnetite veins in fractured magnetic diorite intrusive host rock and surrounding host volcanic rocks (Figure 4).
Importantly the peripheral areas host numerous chalcopyrite, sphalerite (zinc sulphide) and galena (lead sulphide) and quartz / carbonate veins classically emplaced in the peripheral zones around the copper gold rich cores of many South American copper gold porphyry systems.
The Moran Prospect at surface is dislocated to the north by 300 metres and over the top of a strong MVI (Magnetic Vector Image) anomaly at a depth of 350 metres (shallowing to the north towards the outcropping mineralization) which has been defined by the latest 3D magnetic model of the Cascabel Project area. This most up to date iteration of the predictive 3D magnetic model has been recently completed by SolGold's independent geophysical consultants after several months of detailed and sophisticated data treatment and modeling. The magnetic anomaly at a cut-off of 0.06 SI units (a scale measure of magnetic character) which is characteristic of the mineralized zone at the Alpala deposit to the south is 1000m wide x 500m north south (open and shallowing to the north under the mineralization) with a vertical extent of 800m.
SolGold is targeting the magnetic anomaly, extensions northwards and surface mineralization at Moran as prospective for the definition of in excess of a possible large mineral resource in addition to the Alpala Deposit which has to date hosted significant mineralization in 17 of the 18 holes drilled.
SolGold is continuing a program of very detailed soil augering, mapping, rock chip and rock saw channel sampling and assaying to mature the prospect for drill testing, expected in later in 2016.
The discovery of the Moran system brings to 11 the inventory of other orebody targets defined to date at Cascabel:
Alpala - 18 holes drilled for 22,000m - interim maiden resource expected in Q3.
Alpala West - mapping
Alpala South - mapping
Alpala South East - Hematite Hill - mapping
Alpala North East - mapping
Crystal - mapping
Triviņo - mapping
Aguiņaga - geophysical models and augering in preparation for drilling
Moran - mapping and auger sampling in prep for drilling
Tandayama America - mapping
Chinambicito - mapping
These targets are all defined by coincident copper gold molybdenum and magnetic anomalies.
New Magnetic Model for Alpala
A new constrained magnetic model has been completed by the Company's geophysical consultants and has assisted with the identification of the Moran Prospect referred to above. A further unconstrained magnetic model is being revised by the independent consultant and results are expected in July.
Carmen Alpala Road
The Carmen Alpala access road is now within 700 metres of the Alpala Camp and expected to be finished within 6 weeks. The road is expected to provide access for a new drilling contractor with heavier rigs capable of deeper and faster drill holes capable of completing a 2.5km drill hole in 35 days, subject to ground conditions.
New Application Area
ENSA (see About Cascabel, below) has applied for a new exploration area which will be primarily to address the requirements for future plant site waste rock and tailings dams for 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.
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.
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.
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.
