Coro Intersects Further Substantial Copper Mineralization at Marimaca Highlighted by 150m @ 1.13% Cut from Surface

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 6, 2016) - Coro Mining Corp. ("Coro" or the "Company") (TSX:COP) is pleased to announce the results of the remaining 8 holes from a recently completed 16 hole, 2680m reverse circulation (RC) drilling program at its Marimaca copper project, located 22km E of the port of Mejillones in the II Region of Chile, (Figure 1). Results for the first 8 holes were released on April 28 2016.

Drilling Results

All 8 holes, MAR-09 to MAR-16, were drilled in the West Zone, and all intersected significant copper mineralization as shown on Table 1. Results for all 16 holes are shown on Tables 3 and 4. Drill hole locations and mineralized zones are shown on Figure 2 and a long section through the West Zone is shown on Figure 3.

Alan Stephens, President and CEO of Coro commented, "We continue to be impressed by the results received from our first drilling campaign at Marimaca. Subject to financing, we now intend to aggressively advance Marimaca to an initial resource estimate with a view to confirming its economic viability as quickly as possible."

About Marimaca

The Marimaca property contains a number of N-S trending, ~60°E dipping, broad shear zones, cross cut by later NE-SW oriented sub vertical feeder structures, all hosted by Jurassic age intrusive rocks. The intersection of these structures has produced wide NW-SE oriented zones of eastward dipping mineralization that have been exploited from a series of open cuts and small underground workings by artisanal miners (Figure 2).

Surface mapping and drilling has shown that the mineralization is comprised of multiple, thick, higher grade structures bordered by lower grade halos. The long section (Figure 3) shows that the West Zone is comprised of two SE plunging bodies separated by ~50m of barren material. Half of the holes bottomed in mineralization and none of them fully entered the primary sulphide zone. Mineralization is open down dip and along strike although the West Zone appears to be feathering out to the SE as shown by MAR-15, and other zones remain to be tested. The good grades in the oxide zone represent the oxidation of an enrichment blanket, consisting mostly of covellite. Mineralization is associated with potassic alteration and albitization while the wall rocks exhibit calci-sodic alteration.

Acid solubilities in the oxide zones are good at 76% for all assays greater than 0.1%CuT and rising to 81% for all samples greater than 0.3%CuT. This is consistent with previous third party preliminary column test work carried out from surface samples which indicated ~75-85% CuT recovery and ~20-40kg/t net acid consumption. Cyanide soluble copper assays will be completed to define total solubilities in the mixed and enriched zones.

Other significant currently or recently producing deposits in the belt include Mantos Blancos, Michilla, Ivan and Mantos de la Luna. (Figure 1)

Coro has the right to earn a 75% interest in the property as follows;

• 51% interest earned in Compañia Minera Newco Marimaca ("CMNM") with a $125k payment together with completion of a NI43-101 resource estimate and engineering study that demonstrates the technical and economic feasibility of producing a minimum of 1.5ktpy Cu cathode by August 6th 2018 at Coro's cost
• Additional 24% interest in CMNM earned by Coro upon obtaining financing for the project construction
• The owner's interest will comprise a 15% interest free carried to commencement of commercial production and a 10% participating interest subject to dilution. The owners at their election may request Coro to loan them the equity portion corresponding to their 10% interest, if any, recoverable by Coro from 100% of the project's free cash flow after debt repayments
• Coro retains a first right of refusal

Sampling and Assay Protocol

True widths cannot be determined with the information available at this time. Coro RC holes were sampled on a 2 m continuous basis, with dry samples riffle split on site and one quarter sent to the Geolaquim laboratory in Copiapo, Chile by Coro personnel 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 80% passing -10#, homogenizing, splitting and pulverizing a 400 g subsample to 95% passing -150#. All holes were assayed for CuT (total copper) and CuS (acid soluble copper) by AAS. A full QA/QC program, involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results.

About Coro Mining Corp.:

Coro's strategy is to grow a mining business through the discovery, development and operation of "Coro type" deposits. These are defined as projects at whatever stage of development, that are well located with respect to infrastructure and water, which have low permitting risk, and which have the potential to achieve a short and cost effective timeline to production. Our preference is for open pit heap leach copper projects, where we will seek to minimise capital investment rather than maximise NPV, where we will prioritise profitability over production rate, and finally, where the likely capital cost is financeable relative to our market capitalization. The Company's assets include its 65% interest in SCM Berta; the Planta Prat and Marimaca projects; the Llancahue prospect, optioned to Industrias Peñoles; and a royalty on the San Jorge copper-gold project located in Argentina.
