April 22, 2019

Ottawa, ON, Canada: Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSXV:CGP) (Frankfurt:GWN) (Berlin:GWN) (OTC:CTNXF) is pleased to announce that Cornerstone and its subsidiary Cañabrava Mining S.A. have signed a binding option and farm-in Agreement with Newcrest International Pty Limited ("Newcrest"), a subsidiary of Newcrest Mining Limited (ASX: NCM) for Cornerstone's Caña Brava and Tioloma properties in Ecuador (Figure 1) (the "Project"), targeting epithermal gold-silver and porphyry gold-copper deposits in south central Ecuador. This Agreement implements and replaces the Heads of Agreement announced February 19, 2019: 19-05 - Cornerstone and Newcrest sign Option and Farm-in Heads of Agreement for the Caña Brava gold-copper Project in Ecuador

President and CEO Brooke Macdonald said: "Newcrest is one of the largest gold mining companies in the world, operating mines in Australia, Papua New Guinea, and Indonesia, and we are pleased to have entered into this Agreement with them. Newcrest is also partnering with us on the Miocene project in Chile (see news release dated December 10, 2018). We look forward to working with the Newcrest team on these properties.

Cornerstone applauds the Ecuadorian Ministry of Environment (ME)'s issuance in March of Ministerial Accord 020 (amending Ministerial Accord 009 of January 24, 2019), being the regulations for "scout (exploratory) drilling" using up to 30 drill platforms during the initial exploration phase of an exploration project, and the issuance in the last week of the Application Form to obtain an environmental registration the obtainment of which is a condition to benefit from the scout drilling program. Cornerstone is studying the Application Format and expects to make an application for scout drilling in the coming months.

In the meantime, Cornerstone continues to advance its almost completed environmental impact assessment (EIA) for Caña Brava that would provide for drilling during the initial and advanced stages of exploration and beyond during the economic evaluation phase and expects to be submitting the EIA to ME for comments within 4 to 6 weeks' time.

Teams from both companies are already meeting to define work programs and activities to be implemented in the following weeks and months."

About Caña Brava and Tioloma

Caña Brava - Gold/Copper - (Cornerstone has the right to earn 100%)
On February 26, 2015, the Company announced results from prospecting and geological mapping surveys carried out during 2014 on the Caña Brava property located in south-central Ecuador. The release detailing the results can be found at www.sedar.com.

The surveys identified (1) two significant porphyry Cu-Au targets well defined by coincident geological, geochemical and ground magnetic anomalies, (2) an intermediate sulphidation, higher grade, epithermal Au-Ag-Cu veins-breccia system mapped on the northern margin of the porphyry targets, and (3) a high sulphidation epithermal Au-Ag system recognized in the northeast corner of the property. Subsequently, a trenching program was completed (20 trenches, 599 metres, 301 channel samples), spectrometry (Terraspec) work carried out on soil samples (552), rock chips and channel samples (706) and a Phase 1 drill program has been prepared.

An EIA was begun in July 2018, including an environmental base line study and consultation process. Base line study field work has been completed. The EIA will be submitted to the Ministry of Environment (ME) for comment in approximately 4 to 6 weeks' time.

The Company, through an Ecuadorian subsidiary, has the right to earn a 100% interest in the Caña Brava project from the original owner in return for cash option payments of $40,000 every 6 months until the Company decides to exercise the option by making a final payment of $350,000. The $350,000 payment may be made early, the option exercised at any time, and the underlying NSR to the optionor may be purchased for $150,000 at any time.

Tioloma -- Gold/Copper (100% Cornerstone)
Cornerstone acquired the Tioloma property in March 2017 for strategic purposes; the property wraps around three sides of the Caña Brava property, thereby enlarging, and effectively creating a protective area of interest around, the Caña Brava property and on strike with a well-defined regional mineralized trend.
