Cordoba Minerals mobilizes a second drill rig to the Alacran Deposit

in Colombia

TORONTO, CANADA: Cordoba Minerals Corp. (TSX-V: CDB; OTCQX: CDBMF)

(“Cordoba” or the “Company”) is pleased to announce that a second drill rig has been

mobilized to the high-grade, near -surface Alacran Deposit, located within the San

Matias Copper-Gold Project in Colombia.

Further to Cordoba’s August 21, 2017 news release, the drill program that is currently

underway is testing three high- priority targets, which include the new southern strike

extension; the northeast extension across a WNW fault zone; and the down- dip

extensions on the western side of the deposit.

Drilling in the northeast of the fault will target a strong copper-gold soil geochemical

anomaly coincident with mineralized float that is underlain by a chargeability anomaly

and potentially extending under a diorite sill.

Mario Stifano, President and CEO of Cordoba said, “Mobilization of a second rig allows

us to accelerate the pace of drilling at Alacran, the results of which we plan to

incorporate into an updated mineral resource estimate and a Preliminary Economic

Assessment, both expected in the first half of 2018. We are optimistic that this drilling

program will continue to yield significant results for Cordoba.”

Expanding the new southern strike extension target

As reported in Cordoba’s July 25, 2017 news release, drilling encountered high-grade

copper-gold mineralization outside of the current m ineral resource shell, demonstrating

potential to significantly expand the current resource estimate. Drill hole ACD066

indicated that previous drilling in the southern-most part of the property was collared too

far west and that the copper -gold deposit is offset to the east by post -mineralization

faulting, indicating potential for undrilled strike extensions of almost 500 metres.

Highlights from drill hole ACD066 include:

◦ 48 metres @ 0.70% copper and 0.19 g/t gold (0.84% CuEq) from 0 metres,

including:

▪ 12 metres @ 1.13% copper and 0.26 g/t gold (1.32% CuEq) from

20 metres.

◦ 34 metres @ 0.37% copper and 0.14 g/t gold (0.48% CuEq) from 60 metres,

including:

2

▪ 8 metres @ 0.73% copper and 0.37 g/t gold (1.01% CuEq) from

57 metres.

◦ 22 metres @ 0.24% copper and 0.08 g/t gold (0.30% CuEq) from 110

metres

Alacran copper-gold system

The Alacran copper -gold system is located within the San Matias Copper -Gold Project

in the Department of Cordoba, Colombia , 200 km North of Medellin. San Matias

comprises a 20,000-hectare land package. The project contains several known areas of

porphyry copper-gold and IOCG and/or CRD mineralization and gold veins.

The Alacran copper-gold system is located on a topographic high in gently rolling

topography, optimal for potential open- pit mining. Access and infrastructure are

considered favourable.

The Inferred Mineral resources at Alacran are 53.5 million tonnes of 0.70% copper

and 0.37 g/t gold. Alacran is approximately two kilometres southwest of the Company’s

Montiel porphyry copper-gold discovery, where drilling inter sected 101 metres of 1.0%

copper and 0.65 g/t gold, and two kilometr es northwest of the Costa Azul porphyry

copper-gold discovery, where drilling inter sected 87 metres of 0.62% copper and 0.51

g/t gold.

The copper-gold mineralization at Alacran is associated with stratabound replacement

of a marine volcano- sedimentary sequence in a faulted antiformal fold structure. The

deposit comprises moderately to steeply-dipping stratigraphy that is mineralized as a

series of sub- parallel replacement -style zones and associated disseminations. The

mineralization is composed of multiple overprinting hydrothermal events with the main

ore phase comprised of chalcopyri te-pyrrhotite-pyrite that appears to overprint an early

magnetite metasomatic event.

The technical information in this release has been reviewed, verified and compiled by

Christian J. Grainger, Ph.D., a Qualified Person for the purpose of NI 43 -101. Dr.

Grainger is not considered independent under NI 43- 101 as he is a consultant to

Cordoba Minerals. Dr. Grainger is a geologist with over 18 years in the minerals mining,

consulting, exploration and research industries. Dr. Grainger is a Member of the

Australian Institute of Geoscientists (AIG).

The Alacran initial Inferred Mineral Resource estimate was completed by Mining

Associates Limited and reported by the Company on January 5, 2017, and is in

accordance with National Instrument 43- 101 and the 2014 Canadian Institute of Mining

(CIM) definition standards. Inferred Mineral Resources are considered to be too

speculative geologically to have the economic considerations applied to them to be

categorized as Mineral Reserves. Mineral Resources that are not Mineral Reserves do

not have demonstrated economic viability.
