20-20 - Drilling to begin in September at Espiritu target at Bramaderos Gold Project (Ecuador)

  Ottawa, ON, Canada: Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) is pleased to provide an update on its Bramaderos gold and copper joint venture in southern Ecuador in which it has a 12.5% interest carried by JV partner and project operator Sunstone Metals Inc. (ASX: STM) through to the start of commercial production (see "About Bramaderos", below).

HIGHLIGHTS:

  • Drilling at the Bramaderos project in Ecuador to resume early next month, commencing with diamond drilling at the Espiritu gold-silver target, then moving to Brama and Porotillo porphyry gold-copper targets
  • The first drill hole at Espiritu will test the depth extent of the gold-silver polymetallic system which assayed:
    • in trench (channel) samples, 21m at 82.4g/t silver, 0.3g/t gold, 1.4% zinc and 1.2% lead, including 4m at 415g/t silver, 0.9g/t gold, 6.9% zinc and 6% lead; and
    • in surface rock chip samples, 4.2g/t gold and 101g/t silver, 11.9g/t gold and 175g/t silver, and 11.6g/t gold and 2,962g/t silver
  • The Espiritu target, defined on the basis of gold and silver soil anomalies with supporting rock chip samples extends over an area of 800m x 600m with what appears to be multiple parallel mineralized structures

Cornerstone's CEO, Brooke Macdonald, said: "We are excited to resume drilling at the Espiritu gold-silver target and to further test the Brama and Porotillo porphyry targets at Bramaderos. The drill program has been designed by the Sunstone team, headed up by their CEO Malcolm Norris and including Chief Geologist Bruce Rohrlach, both of whom were heavily involved in the early stage work with us to make the discovery at the Cascabel project, when they held the same positions at SolGold."

FURTHER INFORMATION:
Drilling is planned to resume in early September at the highly promising Espiritu gold-silver target area (Figures 1 and 2). An initial 4-hole program, with optional follow-up holes, has been planned.

This phase 1 drilling program will be completed during September with assay results expected in late October.

Several other similar targets (such as Target E11 ) have been identified and will be brought to the drilling stage as soon as possible.

Drilling at the Brama and Porotillo porphyry gold-copper targets is expected to follow drilling at Espiritu.

About Bramaderos
Measuring 4,948 hectares, the Bramaderos project is located approximately 130km from the Loja provincial capital in southern Ecuador. The project is easily accessible via the Pan American Highway that crosses the property.

The Bramaderos concession is owned by La Plata Minerales S.A. ("PLAMIN"), which in turn is owned 87.5% by Sunstone (the project operator) and 12.5% by Cornerstone. Cornerstone's 12.5% interest is carried by Sunstone through to the start of commercial production and repayable at Libor plus 2% out of 90% of Cornerstone's share of earnings or dividends from the Bramaderos project (see news release 20-01 dated January 7, 2020).

More information about the property can be found at www.cornerstoneresources.com.

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
PLAMIN uses a fire assay gold technique for Au assays (FAS-111) and a four acid multi element technique (IMS-230) for a suite of 48 elements. FAS-111 involves Au by Fire Assay on a 30-gram aliquot, fusion and atomic absorption spectroscopy (AAS) at trace levels. IMS-20 is considered a near total 4 acid technique using a 20g aliquot followed by multi-element analysis by ICP-AES/MS at ultra-trace levels. This analysis technique is considered suitable for this style of mineralization.

Standards, blanks and duplicates are inserted ~1/28 samples. The values of the standards range from low to high grade and are considered appropriate to monitor performance of values near cut-off and near the mean grade of the deposit. The check sampling results are monitored and performance issues are communicated to the laboratory if necessary.

Sample security was managed through sealed individual samples and sealed bags of multiple samples for secure delivery to the laboratory by permanent staff of the joint venture. MS Analytical is an internationally accredited laboratory that has all its internal procedures heavily scrutinized in order to maintain their accreditation. MS Analytical is accredited to ISO/IEC 17025 2005 Accredited Methods.

PLAMIN's sampling techniques and data have been audited multiple times by independent mining consultants during various project assessments. These audits have concluded that the sampling techniques and data management are to industry standards. All historical data has been validated to the best degree possible and migrated into a database.

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.
