Coro Announces Results from Marimaca Project Due Diligence

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Oct. 30, 2014) - Coro Mining Corp. ("Coro" or the "Company") (TSX:COP) is pleased to announce that it has completed due diligence on the Marimaca project, located 56km north of the city of Antofagasta and ~22km from the coast at Mejillones, in the II Region of northern Chile, (Figure 1). Based on the results of this work, Coro has elected to proceed to option the project from SCM Compañia Minera Constanza ("Constanza"), on the terms described in the Company's news release of August 13 2014, and is drafting the definitive agreement to do so.

Alan Stephens, President and CEO of Coro commented, "Our due diligence at Marimaca has confirmed the potential we identified initially. Surface sampling and geological mapping indicates that oxide copper mineralization occurs within an eastward dipping shear structure, some 250m in estimated true thickness and exposed over at least 600m. It is currently being exploited in a series of small open pits over a vertical elevation difference of 100-150m by mechanized artisanal miners. The weighted average of 365m of chip channel samples taken at various places along the exposed strike length is 0.49%CuT/0.36%CuS, including an internal waste section, and we are increasingly confident that a significant leachable copper oxide resource may be rapidly defined at Marimaca."

Due Diligence Sampling and Mapping Results

Marimaca is an early stage copper oxide prospect hosted by Jurassic intrusive rocks, with mineralization controlled by a NNE oriented major shear structure, dipping ~50° to the E. Coro took a total of 73 samples from 6 separate continuous chip channels with the following results;

Marimaca Chip Channel Samples
Length (m)	CuT (%)	CuS (%)	%CuS/CuT	Description
150	0.36	0.24	67%	One end in mineralization
incl. 85	0.48	0.32	68%
30	0.53	0.43	80%	Both ends in mineralization
65	0.62	0.49	79%
50	0.10	0.03	31%	Internal waste block
45	0.93	0.71	76%	Both ends in mineralization
25	0.79	0.67	85%
Weighted Av	0.49	0.36	74%	365m incl. internal waste
	0.55	0.41	75%	315m excl. internal waste

The mineralization, occurring as malachite and chrysocolla, appears to be present within the shear as several higher grade, elongated, lenticular zones parallel to strike possibly located in zones of dilation, surrounded by lower grade halos, and separated by internal waste blocks. A series of NS oriented, mineralized, sub vertical structures transect the shear zone. The sampling program was designed to be as representative as possible of the entire shear zone, avoiding focusing on obviously high grade mineralization in existing workings that could have otherwise skewed the overall results. Figure 2 shows the location of the chip channel samples and the shear zone, while Figure 3 is an annotated photograph showing the dip of the mineralized zone.
