Completion of detailed helimagnetic survey marks start of aggressive 2018 exploration program at Bramaderos gold-copper project in Ecuador
OTTAWA, Ontario, Jan. 11, 2018 (GLOBE NEWSWIRE) — Cornerstone Capital Resources Inc. (“Cornerstone” or “the Company”) (TSXV:CGP) (F:GWN) (B:GWN) (OTC:CTNXF) announces that the detailed heli-magnetic and radiometric survey has been completed at its Bramaderos gold-copper project in Ecuador.
The Bramaderos concession exploration targets and figures referred to in this release can be seen in PDF format by accessing the version of this release on the Company’s website (www.cornerstoneresources.com) or by clicking on the link below:
This survey covered the entire 4,949 hectare concession area (see Figure 1), and was flown on 100m spaced, east-west lines.
The heli-magnetic survey data is an important component of the Bramaderos exploration program. The results will be used to map structure, alteration, and intrusive events and the method has been applied successfully by JV partner Sunstone on previous porphyry copper-gold and epithermal gold discoveries.
The raw data from the survey has been reviewed and is high quality. The contractor is expected to deliver a final dataset that will be processed and integrated with other datasets such as geology, soil geochemistry, and trenching to deliver drill targets. It is expected that initial 2-dimensional imagery will be available in 4 weeks.
Drill Permitting Update
The Social Participation Process, public information meeting, and formal information centre for the Environmental Impact Assessment have been concluded and were well received by all project’s stakeholders (communities and authorities) with no negative comments. An updated EIA report, recording the positive local response, has been submitted to the Ministry of Environment. An inspection request has been submitted to SENAGUA for the water permit process.
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).
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.
