Coro Mining Provides an Update on its SCM Berta Operation in Chile

Coro is pleased to announce that commissioning of the crusher, agglomerator and the majority of the heap leach pads has been completed and the operation has commenced ramping up to nominal production of 400 tonnes (880,000 lbs) per month of copper cathode* , which is expected to be reached during Q4 2017. Hauling of Pregnant Leach Solution ("PLS") produced from the first leach pads at Berta started on June 19^th and the solutions are currently being processed in the Nora plant, the capacity of which has been recently increased to 4,800 tonnes (10,582,190 lbs) of copper cathode per year. The metallurgical behaviour of the ore has been excellent, with recoveries meeting the projected leach kinetics for the operation.

Coro is also pleased to announce that it has been granted the Berta plant technical permit while the receipt of the Berta Sur open pit and waste dump permits are expected to be issued in the fourth quarter of 2017.

Production levels in the crushing and agglomeration plant during the ramp up period have reached peaks of 3000 tonnes of ore per day, a level which the Company believes is sustainable. Four of the five pads are currently under leach with a 75 day leach cycle. PLS transportation to the Nora plant is also being ramped up to accommodate the solution volumes generated from the pads. Efficiency at the Nora plant has improved and, as a result, Grade A cathodes are now being produced consistently.

"We are pleased to have completed the commissioning of the Berta plant and look forward to commencing full scale mining at the Berta open pit mine shortly after receiving the final mining permit from the authorities," commented President & CEO Luis Tondo. "Achieving commercial production at SCM Berta will be a major milestone in the evolution of Coro as a junior copper producer, and we look forward to using this experience to fast track the development of our Marimaca project."

*Copper cathode is the copper plate resulting from the Solvent Extraction & Electrowinning (SXEW) process
