Coro Mining Provides an Update on the Infill Drilling Campaign at its Marimaca Project, Chile

Vancouver, British Columbia--(Newsfile Corp. - October 30, 2017) - Coro Mining Corp (TSX: COP) ("Coro or the Company") is pleased to announce that it has advanced according to plan on the infill drilling campaign at its Marimaca project, located 22km east of the port of Mejillones in the II Region of Chile, (Fig. 1).

This program, which is nearing completion, comprises approximately 10,700m metres of reverse circulation drilling for a total of 57 holes using two drill rigs. In addition, a program of approximately 900m metres of diamond drilling in 5 drill holes has commenced in order to provide geotechnical information and a further 4 drill holes for 820m have been completed and which will provide samples for metallurgical column test work in support of the Marimaca Feasibility Study on this property, which is underway as announced at the start of the third quarter.

"The results of infill and geotechnical drilling at Marimaca will inform the definitive feasibility study, which we anticipate completing in the first quarter of 2018. This will allow us to increase the confidence in our resource to produce both a reserve statement and a mine plan," commented CEO Luis Tondo. "The feasibility study will serve the dual purpose of allowing Coro its 75% earn-in to the Marimaca property as well as allowing us to fast track Marimaca to production as per our strategic plan. The first batches of assay results are expected to be released shortly."
