VANCOUVER, BRITISH COLUMBIA--(Marketwired - Oct. 18, 2016) - Coro Mining Corp. ("Coro" or the "Company") (TSX:COP) is pleased to announce the results of the final 23 reverse circulation (RC) holes from the 39 hole, 8530m hole drill program completed at its Marimaca copper project, located 22km E of the port of Mejillones in the II Region of Chile, (Fig. 1). Previous drill results from Marimaca were released on April 28, May 6, September 6 and October 4 2016.

Alan Stephens, President and CEO of Coro commented, "As with the prior results, these final holes intersected attractive mineralization and confirm the extent and continuity of the deposit as we step out from the original drilled area. Only 2 holes out of the entire resource definition drill program did not intersect mineralization and they define the SW margin of the body, which remains open in other directions. Its geometry is confirmed as a 150-250m thick, gently ESE dipping, slab of strongly fractured Jurassic diorite formed at the intersection of the major N striking Marimaca structure and NE striking mineralizing feeder zones. Hypabyssal diorite intrusives are associated with the introduction of chalcopyrite (mainly as veinlets), which was subsequently largely supergene enriched to chalcocite and covellite. The resulting secondary enrichment blanket has been almost completely oxidised to green copper oxides (mostly brochantite and chrysocolla), with lower grade copper wad and black oxides deposited at the peripheries of the deposit during oxidation. The deposit is cross cut by unmineralized late and post mineral dykes and sills.

"Metallurgical column test work is underway and the initial resource estimate is scheduled for completion in November. Due diligence for the acquisition of Minera Rayrock, owner of the ~10ktpy Cu Ivan SXEW plant located ~20km S of Marimaca, (see our August 4 2016 news release), is almost complete. Various development scenarios for the project are being evaluated."

Drilling Results
Latest results are shown on Tables 1 where %CuT means total copper. Drill hole locations are shown on Fig. 2 and a typical cross section on Fig. 3. Acid solubilities for all samples in the oxide zone are good at 72% for all assays > 0.1%CuT and rising to 79% for >0.3%CuT.

Holes MAR-48 to 50 tested geochemical anomalies to the E of the outcropping mineralization. They intersected spotty copper values consistent with their location in the hanging wall pyrite halo of the deposit, now strongly leached to limonite.

Agreement Terms

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. Core from DDH holes was photographed, logged, split and sampled on site by Coro personnel and one half of the core sent to Geolaquim. 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) 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. Samples showing significant secondary sulphides will be assayed for CuCN (cyanide soluble copper) in due course. 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 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 including the Berta and Salvadora deposits; the Marimaca drill stage project; the Planta Prat project; the Llancahue prospect; and a royalty on the San Jorge copper-gold project located in Argentina.
