19-11 - Cornerstone and Newcrest sign definitive Option and Farm-in Agreement for the Caña Brava gold-copper Project in Ecuador

  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 Caņabrava 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 Caņa 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: http://www.cornerstoneresources.com/s/NewsReleases.asp?ReportID=845496

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 Caņa 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 Caņa Brava and Tioloma

Caņa 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 Caņa Brava property located in south-central Ecuador. http://www.cornerstoneresources.com/s/NewsReleases.asp?ReportID=697817

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 Caņa 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 Caņa Brava property, thereby enlarging, and effectively creating a protective area of interest around, the Caņa Brava property and on strike with a well-defined regional mineralized trend.

http://www.cornerstoneresources.com/i/pdf/NR19-09Figures.pdf.

HIGHLIGHTS:

  • 2019 drilling campaign along the greater Alpala trend providing further growth to the Alpala deposit at Alpala NW, Trivinio, Alpala Western Limb and Alpala South.
    • 189,984m of diamond drilling comprising 168 drill holes completed to-date on the Alpala Deposit, representing a further 56,408m of drilling completed since release of the updated mineral resource estimate announced November 20, 2018 ("MRE#2", see below for link to Technical Report filed January 3, 2019), with 6,654m of recent drilling with assay results pending.
  • Updates to in-house models, estimated from an additional 49,794m of diamond drilling since MRE#2, support expectations for resource growth across both indicated and inferred categories.
  • Discoveries of previously unknown high grade (>1.5% CuEq1) and medium grade (>0.7% CuEq) mineralization intersected within existing low grade Inferred Resource areas at Alpala highlight ongoing upgrades to existing resource base at Trivinio (Hole 93), Alpala North (Hole 75), Alpala Northwest (Hole 86), and Alpala South (Hole 89).
  • Drilling highlights:
    • Potential at Trivinio bolstered by Hole 93 intersection: 862m @ 0.43% CuEq (0.32% Cu, 0.16g/t Au, from 1314m depth, 345m true width2), 520m (true width 208m) of which lies outside the existing Inferred Resource area.
    • Alpala North mineralization remains open to the north, as shown by Hole 75 intersection: 1918m@ 0.53% CuEq (0.41% Cu, 0.19g/t Au, from 320m depth, 767m true width), 288m (true width 115m) of which lies outside the existing Inferred Resource area.
    • Discovery of previously unknown QD10 source intrusion at Alpala Northwest, intersected in Hole 86: 318m @ 0.67% CuEq (0.54% Cu, 0.22g/t Au , from 1052m depth, 127m true width, incl. 100m @ 1.34% CuEq), highlights potential for further significant resource extension as the 2019 drilling campaign continues.
    • Alpala South mineralization remains open to the south and towards surface, as revealed by Hole 89 intersection: 420m @ 0.61% CuEq (0.43% Cu, 0.30g/t Au , from 334m depth, 168m true width).
  • Geotechnical, hydrogeological and sterilization drill testing commences at Cascabel, ahead of expected release of Preliminary Economic Assessment (PEA) report.

Cornerstone CEO, Brooke Macdonald, said: "Cornerstone is encouraged by these resource upgrade drilling results, expected to further expand and enrich the existing resource base at the Alpala deposit, as well as resource extension drill hole results outside the previous resource area which promise further growth for the 2019 drilling campaign ahead."

FURTHER INFORMATION:
Cascabel is located in northwestern Ecuador in an under-explored northern section of the Andean Copper Belt (Figure 1).

Mineral Resource Extension & Upgrade -- 2019 Drilling Campaign
The 2019 drilling campaign at Cascabel is presently employing 10 drilling rigs (Figures 2 and 3). The drilling fleet currently has three rigs focused on resource upgrade drilling (Rigs 2, 5, and 7), five rigs focused on resource extension drilling (Rigs 3, 4, 6, 8, and 9), and two rigs focused on geotechnical, hydrogeological and sterilizisation drilling (Rigs 1 and 13).

A further 2 man-portable rigs (Rigs 14 and 15) are under final construction & upgrade phase at the HP Drilling workshops, and are planned to join the Cascabel drilling fleet in May 2019 to expedite geotechnical and hydrogeological drill testing and ongoing monitoring programs.

Ongoing drilling, along the greater Alpala trend is providing further growth to the Alpala Mineral Resource Estimate at Alpala NW, Trivinio, Alpala Western Limb and Alpala South.

Recent drilling supports expectations for future resource growth across both indicated and inferred categories (Figures 4 and 5).

The current in-house database is built from 183,330m of drill core samples, the same number of rock-saw trench samples. This represents an additional 49,754m of diamond drilling since release of MRE#2.

To date a current total of 189,984m of diamond drilling comprising 168 drill holes has been completed on the Alpala Deposit, including 109 drill holes (Holes 1-109), 36 daughter holes, 8 re-drills, and 17 over-runs. This represent a further 56,408m of drilling completed since release of MRE#2. 6,654m of recent drilling has assay results pending.

Discoveries of previously unknown high grade (>1.5%CuEq) and medium grade (>0.7% CuEq) mineralization intersected within existing low grade Inferred Resource areas at Alpala highlight potential for upgrades to the existing resource base at Trivinio (Hole 93), Alpala North (Hole 75), Alpala Northwest (Hole 86), and Alpala South (Hole 89). See Table 1 below.

Cornerstone, and its joint venture funding partner ASX listed Sunstone Metals Inc., have mobilized a drill rig to the Bramaderos site (see Photo 1) and drilling is expected to commence shortly.

First assay results are expected in late May to early June based on an anticipated time frame of 2-3 weeks to complete the first drill hole to a depth of ~500m, followed by 1-2 weeks to complete logging and sampling of the drill hole, and anticipating a turn-around time of approximately 4 weeks for sample preparation and assay results.

Drilling will commence at the Limon target where surface trenching assayed 97.6m at 0.71g/t gold and 0.23% copper over a poorly outcropping porphyry system (see news release 18-18 dated May 29, 2018).

The initial drill program is anticipated to be approximately 5,000m and will also include holes at Bramaderos Main to follow up on historical drilling that intersected 248m at 0.56g/t gold and 0.14% copper and recent surface trenching that delivered 615m at 0.52g/t gold and 0.11% copper (see news release 18-17 dated May 9, 2018), and at West Zone where surface trenching has delivered 15.6m at 6.1g/t gold (see news release 17-40 dated November 8, 2017) (see Figure 1).

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.
