Coro Reports First Infill Drilling Results from its Marimaca Copper Project, Chile
- Drilling highlights include 156m @ 0.72%CuT, 172m @ 0.71%CuT and 60m @ 1.61%CuT
November 09, 2017 - Coro Mining Corp. (“Coro” or the “Company”) (TSX Symbol: COP) is pleased to announce
the results of the initial 11 reverse circulation (RC) holes from the recently completed 57-hole, 11,178-metre
infill drill program completed at its Marimaca copper project, located 22km east of the port of Mejillones in the
II Region of Chile, (Fig. 1). Previous drill results from Marimaca were released in 2016 and a maiden resource
estimate on January 12 2017.
“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.
