Coro Mining Reports First Infill Drilling Results from its Marimaca Copper Project, Chile

"We are very satisfied with the results of this first batch of infill holes, which confirm our expectations from the 2016 drilling," commented Coro President & CEO Luis Tondo. "Although the program continues to define the leachable copper resource, it was exciting to intersect 60 metres at 1.61% total copper in primary sulphide mineralization at the bottom of hole MAR-60. The remaining holes will be released in meaningful batches over the coming weeks and the rig will now commence the exploration drill program described in our news release of November 2 2017. This infill drilling program will inform the Definitive Feasibility Study being conducted on the Marimaca project, both as a requirement for Coro to earn its 75% of this property and as a means of facilitating the fast tracking of Marimaca to copper production."

Drilling Results

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

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.
