Coro Reports Results from Infill and Metallurgical Drilling Programs from its Marimaca Copper Project, Chile

2017-12-05 / @newsfile

 

Vancouver, British Columbia--(Newsfile Corp. - December 5, 2017) - Coro Mining Corp. ("Coro" or the "Company") (TSX Symbol: COP) is pleased to announce the results of a further five reverse circulation (RC) holes and four diamond drill (DDH) holes drilled for metallurgical sampling as part of the infill drill program completed at its Marimaca copper project, located 22km E of the port of Mejillones in the II Region of Chile, (Fig. 1). Together with the previously released 11 infill drill hole results from Marimaca released (November 9th 2017), Coro has now published the results of 16 of the planned 57-hole infill drill program. Additional results will be disclosed in meaningful batches as assays are returned to the Company over the coming weeks.

"We continue to be pleased with the results of the infill drilling program, which support, confirm and increase our confidence in the resource that was defined in the maiden resource estimate for Marimaca released early in 2017," commented Coro President and CEO, Luis Tondo. "The results of this infill drill program will be used to update the mineral resource estimate which we expect to be completed during the first quarter of 2018. We are also excited to be underway with the additional reverse circulation drilling program for the purposes of expanding the Marimaca deposit."

Drilling Results
Results are shown on Table 1 where %CuT means total copper. Drill hole locations are shown on Fig 2. Drill collar coordinates are shown on Table 2.

Sampling and Assay Protocol
True widths cannot be determined with the information available at this time. Coro RC holes were sampled on a 2 metre continuous basis, with dry samples riffle split on site and one quarter sent to the Andes Analytical Assay laboratory in Copiapo, Chile for preparation and assaying. A second quarter was stored on site for reference. Samples were prepared using the following standard protocol: drying; crushing to better than 85% passing -10#; homogenizing; splitting; pulverizing a 500-700g subsample to 95% passing -150#; and a 125g split of this sent for assaying. All samples were assayed for CuT (total copper), CuS (acid soluble copper), CuCN (cyanide soluble copper) by AAS and for acid consumption. A full QA/QC program, involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results. Pulps and sample rejects are stored by Coro for future reference.

Sergio Rivera, Vice President of Exploration, Coro Mining Corp, a geologist with more than 33 years of experience and a member of the Colegio de Geologos de Chile and of the Instituto de Ingenieros de Minas de Chile, was responsible for the design and execution of the exploration program and is the Qualified Person for the purposes of NI 43-101. Alan Stephens, FIMMM, Executive Director of Coro Mining Corp, a geologist with more than 42 years of experience, and a Qualified Person for the purposes of NI 43-101, is responsible for the contents of this news release.

About Coro Mining Corp.:
Coro's strategy is to grow a mining business through the discovery, development and operation projects at any stage of development, which are well located with respect to infrastructure and water, have low permitting risk, and have the potential to achieve a short and cost effective timeline to production. The Company's preference is for open pit heap leach copper projects, where minimizing capital investment and creating profitability are priorities and, where the likely capital cost is financeable relative to the Company's market capitalization. The Company's assets include the Marimaca development project; its 65% interest in the SCM Berta company, which owns the Berta mine and Nora plant and the Llancahue prospect.
