OTTAWA, Ontario, Jan. 11, 2018 (GLOBE NEWSWIRE) -- Cornerstone Capital Resources Inc. (“Cornerstone” or
“the Company”) (TSXV:CGP) (F:GWN) (B:GWN) (OTC:CTNXF) announces that the detailed heli-magnetic and radiometric survey has
been completed at its Bramaderos gold-copper project in Ecuador.

This survey covered the entire 4,949 hectare concession area (see Figure 1), and was flown on
100m spaced, east-west lines.
The heli-magnetic survey data is an important component of the Bramaderos exploration program. The results will
be used to map structure, alteration, and intrusive events and the method has been applied successfully by JV partner Sunstone on
previous porphyry copper-gold and epithermal gold discoveries.
The raw data from the survey has been reviewed and is high quality. The contractor is expected to deliver a
final dataset that will be processed and integrated with other datasets such as geology, soil geochemistry, and trenching to
deliver drill targets. It is expected that initial 2-dimensional imagery will be available in 4 weeks.
Drill Permitting Update
The Social Participation Process, public information meeting, and formal information centre for the
Environmental Impact Assessment have been concluded and were well received by all project’s stakeholders (communities and
authorities) with no negative comments. An updated EIA report, recording the positive local response, has been submitted to the
Ministry of Environment. An inspection request has been submitted to SENAGUA for the water permit process.
About Bramaderos
The Bramaderos concession is owned by Cornerstone subsidiary La Plata Minerales S.A. (“PLAMIN”), which has
signed a binding letter of intent with Sunstone Metals Ltd. (formerly Avalon Minerals Ltd.) (ASX:STM), whereby Sunstone has the
right to earn a 51% interest in the project by spending US$3.4 million over 3 years to complete a phase 1 drill program. If this
first option is earned, Sunstone can go to 70% by funding a bankable feasibility study, and can go to 80% by financing 100% of the
cost of construction of a mine and mill (see news release 17-08 dated April 10, 2017).
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 Bramaderos project for Cornerstone and
has reviewed and approved the information contained in this news release.
Sampling and assaying
Rock samples are collected by PLAMIN’s personnel, placed in plastic bags, labeled and sealed, and stored in a
secure place until delivery by PLAMIN employees to the LAC y Asociados ISO 9001-2008 certified sample preparation facility in
Cuenca, Ecuador.
Rock 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-136, 15.0 g split, Aqua Regia
digestion, ICP-AES/MS finish) and gold by Fire Assay (MSA code FAS-111, 30 g fusion, AAS 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).
Soil samples are dried at low temperature, screened to 80 mesh (MSA code PRP-757), a 15 grams portion is then
assayed for a multi-elements suite (MSA code IMS-136, Aqua Regia digestion, ICP-AES/MS finish).
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 20-25 samples) as part of
PLAMIN’s QA/QC program. Rejects, a 100 g pulp for each rock sample, are stored for future use and controls.
