Coro Mining Reports Remaining Results from Infill Drilling at Marimaca Copper Project, Chile

Gold, Silver & Base Metals

January 17, 2018 (Source) — Drilling highlights include 122m @ 0.79%CuT and 62m @ 0.90%CuT

Coro Mining Corp. (“Coro” or the “Company”) (TSX: COP) is pleased to announce the results of the final 26 reverse circulation (RC) holes from the infill drill program completed at its Marimaca copper project, located 22km E of the port of Mejillones in the II Region of Chile, (Figs. 1 & 2). Together with the previously released results from Marimaca (November 9, December 5, and December 22, 2017), Coro has now published the results of all holes in the program.

“These results complete the drilling for an updated Marimaca resource estimate and Definitive Feasibility Study that is underway,” commented Coro President and CEO, Luis Tondo. “Results from the exploration RC holes completed at La Atomica and NE Marimaca, together with assays from six diamond drill holes completed for geotechnical purposes will be released shortly.”

Drilling Results

Results are shown on Table 1 where %CuT means total copper. Drill hole locations are shown on Fig 3. 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 preparation laboratory in Calama and the pulps then sent to the same company’s laboratory in Santiago for 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.

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.
