Minera Alamos Announces Initiation of Resource Expansion Program for La

Fortuna Gold Project in Durango, Mexico

TORONTO, ONTARIO -- (Marketwired – August 17, 2017)

Minera Alamos Inc. (TSX VENTURE:MAI) (the "Company" or "Minera Alamos") is pleased to

announce that it has hired Robelsis Altamirano, P.Eng. , to manage advanced exploration

activities aimed at expanding the resource base at the Company’s flagship La Fortuna gold

project (“La Fortuna”) in Durango, Mexico. Mr. Altamirano worked previously with the

Company’s Mexican technical team and was the exploration manager for Argonaut Gold’s

(previously Castle Gold) south extension of the El Castillo gold mine. He has extensive

experience (+30 years) managing exploration programs in Mexico with both the Mexican

Geological Service (“SGM” – Servicio Geologico Mexic ano) and numerous independent

mining groups. This included being involved from start -to-finish in the discovery and

delineation of Torex Gold Resources’ Media Luna gold project (current inferred resources of

7.4 million gold equivalent ounces at a grade of 4.48 g/t) in the Guerrero Gold Belt, Mexico.

“We are excited to commence this extensive exploration program to quantify the resource

potential of the entire La Fortuna project area, ” said Miguel Cardona , Vice President of

Exploration for Minera Alamos. “Over the last number of months, we have substantially

increased our understanding of the significant mineralizing events that occurred in the La

Fortuna area and why this was the site of so much historical gold mining activity. The

ability to bring in someone with the experience and capabilities of Robelsis to directly

manage our exploration efforts is a significant opportunity for the C ompany and we are

pleased to welcome him to our expanding team”.

The Company’s geological team, as well as previous owners , confirmed the potential for

significant resource growth at the La Fortuna project. The present Measured and Indicated

mineral resource of the Main Zone 1 (4,800,000 tonnes at 1.99 g/t gold containing 308,000

ounces) is located within a limited 300m strike length which was drilled in the mid-1990s.

Importantly, this drilling occurred on only one of at least four known systems of gol d

mineralization. Although remnants of historic mining activities are present throughout the

project area, no modern drilling or systematic exploration has ever been completed

elsewhere on the project.

Target areas for resource expansion include:

 Mineralization that is evident at surface to the north and also approximately 400 -500m

to the south along strike from the La Fortuna Main Zone resource. These areas were

targeted by previous owners for a second phase drill program in the late 1990s, which

was cancelled due to the depressed gold price environment at that time.

 The highly prospective PN Area located at the north ern end of the land package which

presents the potential for a large bulk tonnage gold/silver system contained within a

shear zone at the intersection of two major fault systems. The system can be followed

at surface for approximately 1.5 km and contains numerous occurrences of old mine

workings with sampling confirming widespread mineralization with gold grades ranging

from approximately 1 to 10 g/t, in addition to 50 to 400 g/t of silver.

 The Ramada Zone located between the Fortuna Main and PN Zones on a parallel fault

structure. Mineralization can be traced at surface for a length of approximately 600m

and exhibits grades up to 40 g /t gold from sampling both at surface and inside of

historic mine workings.

 The recently acquired Cerro Pelon Zone , located to the south of the major E -W fault

system passing through the project area , where it appears the deeper porphyritic rocks

have been uplifted and are now exposed due to erosion. This area also contains historic

workings and was delineated in the past by the Mexican Geological Service (“SGM ”) to

contain a large area (3-5 km in diameter) of anomalous and disseminated gold showings

(0.1 to 10 g/t gold).

The 2017 exploration program has been initiated in preparation for drill ing to commence in

the near future . The C ompany will continue to optimize the program schedule as results

become available with plans to carry through aggressively into 2018. A basic outline of

Phase 1 of the exploration program for the project is outlined below:

 Detailed review of historical data and drill information available for the project;

 Surface mapping and drill t argeting to evaluate potential extensions to the north and

south of the previously drilled resource at the La Fortuna Main Zone;

 Completion of a new geophysical survey for the entire La Fortuna project area using the

known drilled resource as a source to “calibrate” geophysical information;

 Field re view/mapping of the prospective PN Zone aimed at establishing initial drill

targets to better delineate the multiple parallel mineralized structures present on this

epithermal system; and

 Field review/mapping of the large porphyritic gold anomaly discovered previously by the

SGM in the far southern are of the project boundaries.

These statements are based on information currently available to Minera Alamos and Minera

Alamos provides no assurance that actual results will meet management's expectations.

Forward-looking statements include estimates and statements with respect to Minera

Alamos’ future plans, objectives or goals, to the effect that Minera Alamos or management

expects a stated condition or result to occur, including funding and exercise of roya lty

options contemplated under the Investment Agreement with Osisko Gold Royalties Ltd, on

the terms provided for therein or at all, the expected timing for release of an updated

resource and reserve estimate and a preliminary economic assessment on Fortuna and

whether or not the assessment will conclude that mineral production is feasible on a

technical or economic basis, and the ability to successfully develop other mineral exploration

properties now or in the future. Since forward-looking statements are based on assumptions

and address future events and conditions, by their very nature they involve inherent risks

and uncertainties. Actual results relating to, among other things, results of exploration, the
