Minera Alamos Updates Progress at

Guadalupe de los Reyes Gold Project, Sinaloa,

Mexico

TORONTO

AND

VANCOUVER

,

June 18, 2018

/CNW/ -

Minera Alamos Inc. ("Minera Alamos" or

"Company") (TSX VENTURE:MAI)

is pleased to provide an update on development activities at the

Company's

Guadalupe

de los Reyes ("Guadalupe") Project,

Sinaloa

, Mexico. The Guadalupe

Project is one of three gold development projects being advanced within the Company's project

development profile, that also includes the Santana and

La Fortuna

projects, both of which are

awaiting their respective commercial production permits expected this year. The

Guadalupe

project

is one of the most significant historic gold producers in this region of

Mexico

and contains a NI 43-

101 near surface gold resource consisting of the following with significant untapped resource

potential from previously identified mineralized structures that remain undrilled:

Indicated Resource of approximately 6.8 million tonnes with an average grade of 1.73 g/t gold

for approximately 380,100 contained ounces (using a 0.5 g/t cut-off);

Inferred Resource of approximately 3.2 million tonnes with an average grade of 1.49 g/t gold for

approximately 155,200 contained ounces of gold (using a 0.5 g/t cut-off).

"The acquisition of the

Guadalupe

gold project late last year was another strategic addition to the

Company's developing production profile", said

Darren Koningen

, CEO of

Minera Alamos

. "A

significant amount of time and effort was expended by the previous owners to re-establish the

project as one of the premium advanced stage gold assets in this region of Mexico. We are

extremely fortunate to have the opportunity to leverage those efforts for the benefit of

Minera

Alamos

stakeholders. Historical records have already provided an insight into previous heap

leaching testwork completed for the project and also the activities surrounding the small scale vat

leaching facilities that can still be seen at the site. By utilizing the expertise of our operating team,

we plan to rework the overall project development and assess the potential construction of a modern

low capex gold heap leach operation."

In recent months the Company's efforts at

Guadalupe

have advanced along a number of paths

simultaneously. Updates from all phases of this work will be provided as available in the coming

months.

A local exploration office has been established in the community adjacent to the project. Work

is underway to fully review historical project data and to establish priority target areas of known

mineralization for near surface resource expansion drilling.

Mapping of the Mariposa-

Zapote

structure, which hosts the majority of the current surface

resource along strike to evaluate extensions that have not been drilled and could be priority

target areas to expand the resource.

Metallurgical samples have been collected from existing resource drill holes and are being

prepared for gold leaching optimization studies.

Engineering efforts are underway to evaluate the project area and establish locations and

preliminary designs for gold heap leaching facilities suitable for the

Guadalupe

current and

future resources.

Guadalupe

de los Reyes Project Background

Gold and silver were discovered at

Guadalupe

by the Spanish in the late 1700s and mining occurred

in the area for over 150 years up until the 1950s. The main

Guadalupe

underground operation

opened in the late 1800s and to date is the most significant source of gold production in the district.

It is estimated (historical estimates only) to have produced approximately 500-600,000 ounces of

gold and 40 million ounces of silver over its operational life at reported grades of +10 g/t Au and

+500 g/t Ag. Most of the historical production is derived from a single section of mineralized

structures over a length of approximately 2 km. At least eight other mineralized zones have been

identified at site along three structural arms of the same large regional system. In total, the system

mineralization has been mapped at surface over a total combined distance of approximately 10 km.

From the 1950s through the 1980s there was limited activity in the

Guadalupe

area other than

exploration reconnaissance studies. The one exception was a small vat leaching operation that was

constructed and operated by the local concession owner in the late 1980s. It is reported that during

this period approximately 32,000 tonnes of coarse crushed mineralized rock (5 to 6 g/t au) was

leached with cyanide in open vats.

Modern drilling was re-initiated at the

Guadalupe

project area in the 1990s and was targeted at

defining significant area of shallow and lower grade gold/silver mineralization in areas surrounding

the

Guadalupe

underground operations. Since that time, in excess of 40,000 meters of drilling (RC

and diamond) have been completed within the current project boundaries. The resource estimates

for the Project as completed by Tetra Tech Inc. (reported in accordance with CSA National

Instrument NI 43-101 resource requirements) are summarized below.

Notes:

1.

Mineral Resources are summarized as reported in the NI 43-101 Technical Report titled "Updated Technical Report Guadalupe de los Reyes Gold Silver Project" by Tetra

Tech Inc. dated April 16, 2018

2.

To the best of knowledge, information and belief of Minera Alamos, there is no new material scientific or technical information that would make the disclosure of the

mineral resources in the Report inaccurate or misleading.

3.

Mineral Resources were calculated based on a cut-off grade of 0.5 g/t Au.

4.

No Measured Resources of Mineral Reserves of any category were identified.

5.

Mineral Resources are not Mineral Reserves and by definition do not demonstrate economic viability. There is no certainty that all or any part of the Mineral resources will

be converted into Mineral Reserves.

Guadalupe Property Terms

Pursuant to the terms of the

October 23, 2017

Agreement, the Company is earning 100% by paying

Vista Gold a total of

US$ 6.0 million

in staged payments as follows:

US$ 1.5 million

on closing

(paid),

US$ 1.5 million

on each of the 12 and 24 month anniversary dates in order to maintain the

option and a final purchase price of

US$ 1.5 million

on or before the earlier of (i) an announcement of

a construction decision by the Company, or (ii) the 48 month anniversary of the Agreement.

Production from any open pit mining operations at the Project (the "Open Pit Royalty") will be subject

to a minimum 1% net smelter return royalty ("NSR") payable to Vista Gold which could increase up

to 2% if gold prices exceed

US$ 1,600

per ounce. This royalty is capped at

US$ 2 million

. Vista

Gold also retains the right to acquire a 49% non-carried interest in the development of underground

gold resources should the Company decide at a later date to pursue potential zones of deep

mineralization (excludes all open pit accessible mineralization).
