Almaden Reports Successful Advance of Community Water Project

Vancouver, B.C. Further to its press release of March 9, 2020, Almaden Minerals Ltd. (“Almaden” or

“the Company”; AMM: TSX; AAU: NYSE American) is pleased to announce that the irrigation dam

developed by the Company in partnership with the Federal Government water authority (“CONAGUA”) and

a local irrigation group from the community of Zacatepec, is now in operation.

Since the completion of construction in March, the reservoir has filled with water, additional equipment

including pipelines and filters have been added, and the first crops are now being grown. On December 8th,

the water users of Zacatepec hosted an event marking the success of this project to which they invited

representatives of CONAGUA and the Company.

This reservoir is one of the social investment projects identified by the Company and its consultants which

could bring immediate benefits to the local area even prior to Ixtaca development.

Almaden has been supporting local initiatives for many years and is pleased to do so particularly when it

can be as impactful as enhancing access to fresh water and expanding local irrigation capacity . As the

Ixtaca project advances we look forward to additional projects we can support in partnership with local

communities and authorities which enhance and diversify economic development opportunities in the

region of the Ixtaca project.

A video describing this project and including interviews with the local users is available at the following URL

Photos of the reservoir are attached below, and additional information regarding Almaden’s interaction with

this and other local communities is available on its website and in its 2019 report on Corporate Social

Responsibility.

Background to the Ixtaca Project and Water Management

Almaden’s active engagement with communities local to the Ixtaca project continues. The Company has

now hosted 57 community dialogue and technical sessions locally with subject matter experts where

appropriate, and offered opportunities to local people tour active mines with 500 people participating to

date. The Company has had over 20,000 recorded interactions and h as visited 35 communities with a

mobile information module while holding nine large information meeting attended by over 4,100 people

since 2012.

Almaden’s long-standing consultation with communities local to the Ixtaca project was formalized in 2017

under the highly structured social engagement mechanism known in Mexico by its acronym, “EVIS”

(Trámite Evaluación de Impacto Social) . This effort has given the Company a deep appreciation for the

immediate needs and concerns of local people and generated val uable input to Ixtaca project design .

Understanding areas of concern that can be mitigated in mine development, and also identify ing

opportunities which can be leveraged in mine planning, has enhanced the project’s potential to permanently

boost the quality of life and economic opportunities in local areas.

For example, t his engagement was one of the key reasons for the Company to adopt dry -stack filtered

tailings, as laid out in the 2019 Feasibility Study . It has also helped to crystallize planning around the

construction of a large water reservoir (different from the one announced today in Zacatepec) which will be

built during construction and will serve the mine and local communities during mine operations. This

reservoir will be built as a permanent structure and made available to local governments at no charge upon

mine closure to permanently enhance local agriculture and community water access . Currently,

communities in Ixtaca lack the infrastructure to fully benefit from surface water and the ma jority of this

resource is lost or underused without the type of reservoir planned as part of the mine development.

The data necessary for planning the water reservoir has been collected since 2014 by Almaden, with

independent engineering oversight. Together with our consultants we have maintained a detailed water

monitoring program to measure the pre-mining water quality conditions and to establish a baseline against

which potential future impacts to surface water and groundwater from mining activity can be evaluated.

The program includes 8 groundwater monitoring wells and 12 surface water monitoring stations. Rainfall in

the Ixtaca vicinity falls primarily during a relatively short rainy season. With no local water storage facilities,

as noted the flash flows of water are currently lost to the local communities.

In the 2019 Feasibility Study , a larger water reservoir to be built at the time of mine development is

engineered to store 1.8 million cubic meters of water , and during operations is anticipated to supply in

excess of 2,000 cubic meters of water per day to local areas, with a minimum of 500 cubic meters per day.
