Coro Mining Marimaca Exploration Update:

Northeastwards Continuation of Mineralization at Tarso

Highlighted by 82 metres at 0.72% CuT

Vancouver, British Columbia, July 30, 2019 – Coro Mining Corp. (“Coro” or the “Company”) (TSX: COP) is

pleased to provide an update for the Marimaca Project in the Antofagasta Region of Chile .

Results have now been received from 40 RC holes for a total 9,950 metres in and around the Tarso area. The

drill results confirm the extension of mineralization from Atahualpa towards the north-east with the Tarso holes

also delineating the edge of mineralization. These results mark the completion of the Phase II RC drilling program

and will be incorporated in the expanded resource calculation which remains on track for publication by the end

of September 2019.

Highlights

Results from the drilling confirmed oxide mineralization, including:

• Hole ATR-99, from 56 to 138 metres, 82 metres averaging 0.72% CuT

• Hole ATR-101, from 68 to 126 metres, 58 metres averaging 0.60% CuT,

including from 78 to 116 metres 38 metres averaging 0.96% CuT

• Hole ATR-102, from 68 to 84 metres, 16 metres averaging 1.12% CuT

• Hole ATR-104, from 60 to 86 metres, 26 metres averaging 0.87% CuT,

and from 108 to 122 metres, 14 metres averaging 0.87% CuT

Results from the drilling confirmed mixed oxide-enriched sulphide mineralization, including:

• Hole ATR-98, from 134 to 144 metres, 10 metres averaging 0.68% CuT,

including from 118 to 138 metres, 20 metres averaging 1.45% CuT

• Hole TAR-13, from 66 to 786 metres, 10 metres averaging 1.65% CuT

Results from the drilling confirmed primary sulphide mineralization, including:

• Hole ATR-62, from 236 to 246 metres, 10 metres averaging 1.30% CuT

• Hole ATR-63, from 240 to 258 metres, 18 metres averaging 1.13% CuT

• Hole TAR-04, from 204 to 226 metres, 22 metres averaging 0.72% CuT

Commenting on the results, Sergio Rivera, Vice President of Exploration said: “The Tarso sector is the final area

to be explored in the expanded Marimaca Phase II exploration program. The results are positive as they confirm

further extension of the mineralised zone at Marimaca into the Tarso area and the mineralized body at Marimaca

now measures approximately 1,400 metres in length , by 700 metres wide and is 100 to 300 metres thick,

averaging approximately 120 metres.

Furthermore, as results reported from Atahualpa last month, where some drill hole returned primary sulphide

intercepts, it is interesting to see more drilling intercepts with some high grade copper sulphide mineralization

at Tarso that may warrant additional exploration.”

Further Information

The final 40 RC holes for 9,950 metres in the Tarso and Atahualpa areas concludes the RC drilling for the

Marimaca Phase II program.

These drill results confirm the extension of the Marimaca deposit in a north-easterly direction over a 400-metre-

long by 300-metre-wide area. The green line in Figure 1 shows the interpreted limits of the Marimaca copper

oxide mineralization in the central area targeted by the Phase II exploration program.

Marimaca Phase II Program

These results comprise the final RC drill holes for the Phase II program. A smaller diamond drill hole program

oriented to check structural controls, provide additional information about the nature of the mineralization and

for obtaining geotechnical data and samples for metallurgical test work is nearing completion , with results

anticipated in the coming months.

All drill holes will be incorporated with the already published Phase I resource into a single enlarged Phase II

resource by the end of September 2019. With the field work largely complete, the Company will now assemble

the lithology-structure and mineralization zones model, the 3D geologic model, data base review, QaQc

reporting, density measurements and bore hole measurements of structural data interpretation, plus th e

integration of all sampling and geologic data obtained along the underground workings. It is intended to publish

progress updates and share findings between now and the publication of the resource.

Sampling and Assay Protocol

True widths cannot be determined with the information available `at this time. Coro RC holes were sampled on

a 2-metre continuous basis, with dry samples riffle split on site and one quarter sent to the Andes Analytical

Assay preparation laboratory in Calama and the pulps then sent to the same company’s laboratory in Santiago

for assaying. A second quarter was stored on site for reference. 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), CuS (acid soluble copper), CuCN (cyanide soluble copper) by AAS and for acid consumption.

A full QA/QC program, involving insertion of appr opriate blanks, standards and duplicates was employed with

acceptable results. Pulps and sample rejects are stored by Coro for future reference.

Qualified Persons

The technical information in this news release, including the information that relates to geology, drilling and

mineralization of the Marimaca Phase I and II exploration program was prepared under the supervision of, or

has been reviewed by Sergio Rivera, Vice President of Exploration, Coro Mining Corp, a geologist with more than

36 years of experience and a member of the Colegio de Geologos de Chile and of the Institute of Mining

Engineers of Chile, and who is the Qualified Person for the purposes of NI 43-101 responsible for the design and

execution of the drilling program.

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 style of mineralization which challenges accepted exploration wisdom and promises to

open up new frontiers for discoveries elsewhere in the cou ntry. Unusually, Marimaca is a fracture controlled

and intrusive hosted deposit while the numerous and well known manto deposits in the same Coastal Copper

Belt are hosted by favourable volcanic rocks.

With a lack of new copper exploration discoveries in Chile the growing Marimaca resource is likely to make it a

sought-after development project as it is located near the coast at low elevation close to the city of Antofagasta

and the port of Mejillones. This prime location should enable its future developmen t at a relatively modest

8

capital investment. Marimaca would benefit from nearby existing infrastructure including roads, powerlines,

ports, a sulphuric acid plant, a skilled workforce and seawater.
