Major Shareholders Extend Working Capital Facility to Continue

Support for the Marimaca Project

Vancouver, British Columbia, March 19, 2020 – Coro Mining Corp. (“Coro” or the “Company”) (TSX: COP) today

announced that it has entered into an unsecured working capital facility (“WCF”) with its major shareholders,

Greenstone Resources II LP (“Greenstone”), and Tembo Capital Mining Fund II LP (“Tembo”) (together “the

Lenders”), pursuant to which the Lenders have agreed to lend up to US$6.0 million to Coro to fund the Company

through these challenging times.

The WCF has a 12-month term from the date of closing and bears interest at 12% per annum. Greenstone and

Tembo will receive an aggregate 3% arrangement fee under the WCF, which will be payable at maturity. The

proceeds of the WCF will allow Coro to continue its exploration and development plans, in a measured fashion,

for its flagship Marimaca Copper Project (“Marimaca” or “the Project”), while removing the need to raise equity

in this Coronavirus emergency market environment. Drawdown by the Company under the WCF is subject to

the approval of the Toronto Stock Exchange.

Michael Haworth, Executive Chairman of Coro Mining Corp commented:

“Greenstone and Tembo continue to believe Marimaca is one of the standout copper development stories

globally and this further investment underlines that fact.

“Current market conditions are unprec edented. We will be exercising a high degree of capital discipline and

limiting cash burn wherever possible, while recognizing the safety of our personnel and maintenance of our

assets being our key objectives.

“We do believe that continuing to advance the development of Marimaca, in a measured fashion, while avoiding

issuing equity, is in the interest of our shareholders. We will continue to monitor the broader market conditions

and adjusting our strategy as appropriate. This WCF gives the Company the fle xibility required within this

operating environment.”

Marimaca Copper Project Overview

Coro recently released an updated Mineral Resource Estimate (“MRE”) for Marimaca of 420Kt of contained

copper with an average grade of 0.60% copper within the Measured & Indicated Categories and 224 Kt of

contained copper with an average grade of 0.52% copper within the Inferred Category ( refer release on 2

December 2019). This represents an increase of almost 100% from the MRE released in April 2018 and makes

the Project one of the most significant copper oxide discoveries in Chile in the last decade.

The Company is currently undertaking a Preliminary Economic Assessment (“PEA”) for the Project, which is

anticipated to be completed in the first half of 2020. The Project is expected to benefit from low upfront capital

development costs and, due to the favourable geometry of the orebody and relatively simple oxide processing,

through Solvent Extraction-Electrowinning (“SX-EW”), Management believes the Project will have competitive

operating costs,.

Coro Mining and the Marimaca Project

Marimaca is fast becoming recognised as one of the most significant copper discoveries in Chile in recent years

as it represents a new type of deposit which challenges accepted exploration wisdom and promises to open up

new frontiers for discoveries elsewhere in the country. Marimaca is hosted by intrusive rocks while the

numerous manto deposits in the same region are hosted by volcanics. Wit h a lack of new copper exploration

discoveries in Chile, the growing Marimaca resource is a high-profile development project as it is situated in the

coastal belt at low elevation close to Antofagasta and Mejillones. This prime location could enable its fu ture

development at a relatively modest capital investment. Marimaca will benefit from nearby existing

infrastructure including roads, powerlines, ports, a sulphuric acid plant, a skilled workforce and seawater.
