Cornerstone Capital Resources Inc. completes Miocene (Chile) property earn in

OTTAWA, May 17, 2017 - Cornerstone Capital Resources Inc. (“Cornerstone” or “the Company”) (TSX-V:CGP) (Frankfurt:GWN) (Berlin:GWN) (OTC:CTNXF) announces that, effective April 28, 2017, it completed its earn-in requirements under the Miocene (Chile) Property Agreement and amended that agreement to eliminate any remaining work obligations of Cornerstone.

Under the amended Agreement Cornerstone now has acquired an undivided 100% interest in any existing and future concessions acquired using a proprietary database within the Miocene Project area having made option payments totaling $250,000 and $250,000 in common shares of Cornerstone and having satisfied all required work commitments (all amounts are CAD$). The Company has incurred exploration expenditures to date of $1,321,059, and is not required to incur any further work expenditures.

On November 4, 2014 the Company announced the re-start of work at Miocene during the austral summer. Five prospective areas defined by previous compilation and exploration work within the Miocene property were the focus of the recent exploration program: El Chaco, Zona Norte, Llano Blanco, Cerro Bayos Norte and Cerro Bayos Sur. Semi-detailed geological mapping (scale 1:5000) and systematic rock geochemical sampling were carried out in these five areas. 390 rock samples were collected, assayed for precious metals (gold and silver) and a suite of base metals and epithermal pathfinder elements. Spectrometry work (ASD TerraSpec) was carried out on all rock specimens (478 samples) collected during the 2011 to 2014 field programs.

Two sub-parallel NW-SE oriented alteration / anomalous trends affect the volcanic units present on the property. The Cerro Bayos (CB) alteration zone covers an area of approximately 9km by 3km and is located in the SW extension of the Atlas Gold, Atlas Silver and the Pampa epithermal prospects. Alteration minerals (native sulphur, predominant alunite, vuggy and massive silica and some silica-clay in the peripheral parts) and 3D distribution mapped along this trend are typical of high sulphidation epithermal system, centered on the highest part of Cerro Bayos Norte (CBN), with the top of the paleo-phreatic zone estimated to be at approximately 4260 masl. Similar alteration patterns are present at Cerro Bayos Sur (CBS) where the top of the paleo-phreatic zone at this location is estimated at 4150 masl. High temperature alunite and high crystallinity kaolinite minerals are centered on the CBN and CBS zones, with some minor presence within the Llano Blanco trend to the south. The aerial extent of the prospective CBN and CBS alteration zones are at least 5 km by 3 km and 4 km by 2.5 km but can possibly be significantly larger as they are partly covered by a thin veneer of relatively fresh younger volcanic rocks and gravels.

Rock geochemical anomalies defined on the Miocene property are very similar in distribution and intensities to anomalies defined during the regional prospecting program in the vicinity of the Atlas Gold and Silver prospects located to the NW. As expected in the upper part of this epithermal environment, the gold content is systematically low. Strong arsenic and mercury anomalies are present at El Chaco, CBN and CBS and to a minor degree at Azufre and Silice Masiva zones. Barium anomalies are present at CBN, Llano Blanco Norte and Cerro Azufre. Molybdenum is anomalous at CBN, to the NE of CBN and to a minor degree at CBS, Llano Blanco Norte and Silice Masiva zones. A large and strong copper anomaly is present at CBN and some less intense but widespread anomalies at Llano Blanco Norte and Cerro Azufre sectors. Sulphur anomalies are present at CBN, CBS, Llano Blanco Norte and Cerro Azufre. See Figures.

Cornerstone’s Miocene concessions lie adjacent to Mirasol Resources Ltd.’s Atlas Gold, Atlas Silver and Pampa projects, where recent exploration programs by Mirasol and JV partner Yamana Gold Corporation confirmed the presence of a significant high-sulphidation epithermal gold system sitting above a postulated mineralized intrusion at depth.

The Company is encouraged by early results from Mirasol’s projects, which serve to support the conceptual model utilized in acquiring the Miocene concessions. The Company continues to seek a partner to help advance exploration on this exciting early-stage project.

For the next austral field season, it is planned to carry out a ground magnetic survey and a trenching program over most prospective areas to further define and prioritize targets to be drill tested.
