Centenera Stakes Ana Maria Project Salta Province, Argentina Plans Q4 Exploration

Centenera Stakes Ana Maria Project

Salta Province, Argentina

Plans Q4 Exploration

Vancouver, British Columbia – Centenera Mining Corporation ( “Centenera” or the “Company”) - (TSXV: CT, OTCQB:

CTMIF) announces staking of Ana Maria project (“Ana Maria ” or the “ Project”) and plans for initial reconnaissance

exploration and surface geochemical sampling in Q4 2018.

Ana Maria Acquisition

The Project was acquired through staking and comprises three separate exploration claims , totalling almost 10,000

hectares and located in the vicinity of the Company’s Organullo gold project (the “Organullo District”).

“Staking opportunities are rare in Salta Province where prospective ground is at a real premium.” stated Keith Henderson,

Centenera’s President & CEO, “Property acquisitions in this region are generally achieved through option agreements with

underlying owners, which can be expensive. With this acquisition , Centenera has an opportunity to assess and explore

this large prospective area with an extremely low acquisition cost.”

Planned Exploration

To the best of the Company’s knowledge, the Project has not been subject to prior exploration, at least not in recent times.

Centenera has considerable expertise in the Organullo District and regionally in Salta Province. The area is prospective for

epithermal gold deposits and associated mineralization. The Company possesses considerable amounts of regional

exploration data that will aid initial exploration and targeting. This data includes extensive BLEG sampling results covering

prospective belts in northwest Argentina, which was collected in partnership with Newmont in 2008. The Company also

has interpreted regional satellite imagery, regional geophysical data, and various other geological and geochemical data

sets.

Next steps will include initial reconnaissance of the Project areas to determine where initial exploration should focus.

Thereafter, exploration will likely focus on detailed surface geochemistry.

to 31.6 million tonnes grading 0.92 g/t gold (940,000 oun ces) using a 0.5 g/t gold cut -off-grade. It should be noted that

these potential exploration target quantities and grades are conceptual in nature, that insufficient exploration and

geological modelling has been done to define a mineral resource, and that it is uncertain if further exploration will result

in the delineation of a mineral resource.
