17-36 - Cornerstone announces Bramaderos property (Ecuador) West Zone trench assays of 8.9m at 6.1g/t gold

 Ottawa, ON, Canada: Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) is pleased to announce further results from the initial field program at its Bramaderos Gold-Copper Project in southern Ecuador where its subsidiary La Plata Minerales S.A. ("PLAMIN") has signed a binding letter of intent with Sunstone Metals Ltd. (formerly Avalon Minerals Ltd.) (ASX: STM) whereby Sunstone will have the right to earn a majority interest in the project subject to satisfaction of certain conditions (see news release 17-08 dated April 10, 2017).

  • Further strong results from five additional trenches completed at the West Zone epithermal gold prospect;
    • Trench 8 : 8.9m at 6.1g/t Au, open in all directions
    • Trench 5: 12.3m at 0.9 g/t Au, including 2m at 2.1g/t Au, open
    • Trench 7: 11.6m at 1.8g/t Au
    • Trench 6: 8.4m at 1.2g/t Au
    • Highest individual sample 1m at 12g/t Au
  • This is the second batch of strong trenching results from West Zone, with the final batch expected later this month
  • The results from the three batches will be used to identify drilling targets and drilling approvals are expected by the end of this year
  • The trenching results present a robust continuous bedrock sample across the mineralized system and as such are comparable to a horizontal drill hole sample at surface

Further Information:
The new results, complementing those released on September 25, 2017, add to the emerging picture of a hydrothermal breccia-hosted epithermal gold system, with a surface footprint of at least 150m x 150m and depth extent to be tested by drilling.

These trenches present a continuous sample of bedrock across and within the mineralized zones. Much of the area is covered by scree on hill slopes limiting the lateral extent of some trenches. As a result, the lateral extent of mineralization is yet to be defined, but is expected to be larger than the limited area of trench sampling to date.

This area has never been drilled and represents a prime target for drilling once the drilling permit is received, which is expected by the end of this year.

Intervals shown in bold relate to the latest set of results; see Cornerstone News Release dated September 25, 2017 for further detail on the first set of results from trenches 1-4, & 6.

The surface trench results are significant because they follow a partially outcropping epithermal system which then continues under cover (scree on the slopes of hills). The trench data, soil data, surface mapping, and a planned detailed heli-magnetic geophysical survey to be conducted in November and December will provide all required datasets for drill targeting.

The final batch of assays from the completed trenching program at West Zone are expected in late October and all data from this prospect will be summarized at that time and reported.

Drill Permitting
A drilling permit is required prior to commencement of drilling. The permit application process requires community consultation of the drilling program with local communities, authorities and landowner groups, and receipt of a water use permit. The water use permit application has been submitted to the water agency SENAGUA (Secretaria Nacional del Agua)and technically pre-qualified. Cornerstone is managing this process and has previously implemented the same procedure at its other exploration properties in Ecuador over the past 10 years. The target for receiving a drill permit by the end of 2017 remains in place.

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).

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.
