CORO ANNOUNCES NORA PLANT COMMISSIONING, RECEIPT OF CONVERTIBLE DEBENTURE TRANCHE 2 FUNDS & DRILL RESULTS

Coro Mining Corp.'s subsidiary, SCM Berta, has completed the remediation and refurbishment of its Nora SX/EW (solvent extraction/electrowinning) plant, located in the III region of Chile. Key management positions have been filled and plant commissioning is nearing completion, with crushing, agglomeration, stacking and testing of fluid flows in progress. SCM Berta anticipates that production of copper cathode will start before year-end once the plant suspension order, referred to in the company's June 16, 2015, news release, has been lifted. The plant will be treating dump material for the next several months prior to initiating mining at Berta itself.

Coro also announces the closing of the second tranche of the convertible debenture with Greenstone Resources LP, which forms part of a larger approximately $9-million (U.S.) combined convertible debenture ($6.5-million (U.S.)) and equity financing (approximately $2.5-million (U.S.)) that was previously announced on June 16, 2015. The second tranche comprises $1.4-million (U.S.), which is repayable on the date that is 350 days after the date of drawdown and requires repayment of $1.75-million (U.S.) resulting in an effective interest rate of approximately 25 per cent. The proceeds of the second tranche will be used to complete the commissioning and start-up of the Nora plant. In the event that the amounts are not repaid in full in cash, any unpaid amounts will be converted into common shares of Coro at a conversion price of four cents per share.

In addition, Coro is pleased to announce the results of SCM Berta's recently completed, six-hole (552-metre) diamond drilling program and 15-hole (1,240-metre) reverse circulation drilling program at the Berta property. The objective of the diamond drilling program was to provide further definition of the higher-grade mineralization, samples for additional metallurgical column test work and improved geotechnical data for pit slope design. The objective of the reverse circulation program was to provide improved definition of the limits to the various Berta Central deposits. All of these objectives were completed satisfactorily and the information derived will be used for production planning purposes.

Alan Stephens, president and chief executive officer of Coro, commented: "We are pleased to be finally commissioning our Nora plant and look forward to initiating production of copper cathode before the end of the year. The lifting of the suspension order is a condition precedent for the remaining equity portion of the Greenstone financing, as described in our Aug. 10, 2015, news release, and we anticipate that this will be satisfied shortly. We are pleased with the results of our drilling, which has further defined the higher-grade cores of the Berta Sur and Central deposits as highlighted by oxide intersections of 56 metres of 0.73 per cent total copper from surface in BD-02 and 60 metres of 1.09 per cent total copper from 10 metres depth in BD-05, respectively. Finally, we have received the second annual option payment of $200,000 (U.S.) in relation to its Llancahue property as described in our news release of Nov. 6, 2014."

No significant mineralization was intercepted in 
holes BR-94, BR-97, BR-101 to BR-104 and BR-107.

All reverse circulation drill holes were sampled on a two-metre continuous basis, with samples riffle split on site and one-quarter sent to the Andes Analytical Assaying laboratory in Copiapo for preparation and then to its assay laboratory in Santiago. A second quarter was stored on site for reference. All diamond drill holes were logged, photographed and split by core splitter prior to sending half to the same laboratory facilities for preparation and assaying. Samples were transported to the laboratory by Andes Analytical Assaying under the supervision of the company's contractor, Geominco, which also logged the drill cuttings and drill core. Samples were prepared using the following standard protocol: drying, crushing to better than 80 per cent passing minus 10 microns, homogenizing, splitting and pulverizing a 400-gram subsample to 95 per cent passing minus 150 microns. All holes were assayed for total copper and molybdenum, with intersections containing greater than 0.1 per cent total copper also assayed for copper sulphide and gold. A full quality assurance/quality control program involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results.

The conclusions of a preliminary economic assessment for the Berta project were announced in the company's news release of June 16, 2015, and an amended and updated technical report dated Sept. 24, 2015, is available on the company's website and on SEDAR. More detailed engineering studies have not been completed, and so the normal progression from preliminary economic assessment to preliminary feasibility study to feasibility study has not been followed in respect of making a production decision at the Berta operation. Therefore, investors are cautioned that no mineral reserves have been declared, and the level of confidence in the resources, metallurgy, engineering and cost estimation is not at a level normally associated with a project reaching a production decision. This may result in the production rates, copper recoveries and operating costs stated in the preliminary economic assessment not being realized.
