ALMADEN CONFIRMS HIGH GRADE VEIN ZONE OUTSIDE OF AMENDED PEA PIT, HITS 1.0 METER OF 6.19 G/T GOLD, 1250 G/T SILVER

WITHIN BROAD ZONE OF VEINING

RETURNING 70.43 METERS OF 0.44 G/T GOLD AND 54 G/T SILVER

Almaden Minerals Ltd. ("Almaden" or "the Company"; AMM: TSX; AAU: NYSE MKT) is pleased to announce assay results from Almaden's ongoing exploration and development program at the Company's Tuligtic project, Mexico. Drill hole TU-16-318A was drilled from the bottom of hole TU-13-318 which in 2013 stopped short of the vein zone reported today. By deepening this hole the Company was able to confirm a zone of veining intersected up-dip in hole TU-11-056, which in 2011 hit two high grade veins that returned 1.26 meters of 2.45 g/t gold and 854 g/t silver and 0.95 meters of 13.86 g/t gold and 2577 g/t silver respectively. Results have also been received from hole TU-16-462 drilled above TU-11-056. This hole also intersected the vein zone and hit two intervals, 0.74 meters of 1.26 g/t gold and 203 g/t silver and 0.52 meters of 0.28 g/t gold and 297 g/t silver respectively. Further holes have been drilled on this section and results are pending. The mineralisation intersected in all holes is limestone hosted and located outside of the 2016 Amended PEA pit. Highlights from holes TU-16-318A and TU-16-462 include the following intercepts:

The mineralisation reported today confirms the presence of additional important zones of veining immediately adjacent to the Ixtaca Zone and points to the exploration potential of the project in general. The Ixtaca Zone was discovered in 2010 beneath a large area of largely barren clay alteration which has been confirmed subsequently to represent the upper portions of a gold and silver bearing epithermal vein system. Since the discovery Almaden has focussed its efforts on the development of the Ixtaca Zone, however today's results

clearly show the potential for additional mineralisation, not only proximal to the deposit, but more broadly project wide beneath the high level clay alteration.

Currently, geotechnical drilling relating to ongoing pre-feasibility work is nearing completion while exploration drilling is ongoing and further exploration results will be reported once received. Recently the Company released a positive Preliminary Economic Assessment ("PEA") on the Ixtaca deposit (see news release dated December 9th, 2015). Approximately 97% of the mineral resources incorporated into the updated PEA mine plan were in the Measured and Indicated categories.

About the Ixtaca Drilling Program and the Ixtaca Zone

The Ixtaca Zone is a blind discovery made by the Company in 2010 on claims staked by the Company. The deposit is an epithermal gold-silver deposit, mostly hosted by veins in carbonate units and crosscutting dykes ("basement rocks") with a minor component of disseminated mineralisation hosted in overlying volcanic rocks.

The Ixtaca deposit is located in a developed part of Mexico in Puebla State, the location of significant manufacturing investments including Volkswagen and Audi plants. The deposit is accessed by paved road and is roughly 20 kilometres from an industrial park with rail service where significant manufacturers such as

Kimberly Clarke have facilities. Any potential mining operation at Ixtaca would be located in an area previously logged or cleared with negligible to no current land usage.

The Company has access to the entire project area and works closely with local officials and residents. The Company has employed roughly 70 people in its exploration program who live local to the Ixtaca deposit. For example, local employees have made up virtually all the drilling staff and have been trained on the job to operate the Company's wholly owned drills. The Company has implemented a comprehensive science based and objective community relations and education program for employees and all local stakeholders to transparently explain the exploration and development program underway as well as the potential impacts and benefits of any possible future mining operation at Ixtaca. The Company regards the local inhabitants to be major stakeholders in the Ixtaca deposit's future along with the Company's shareholders. Every effort is being made to create an open and clear dialogue with our stakeholders to ensure that any possible development scenarios that could evolve from the anticipated PFS are properly understood and communicated throughout the course of the Company's exploration and development program. To better explain the impacts of a mining operation at Ixtaca the Company has conducted numerous tours for local residents to third party operated mines in Mexico so that interested individuals can form their own opinions of mining based on first-hand experience. The Company invites all interested parties to visit www.almadenminerals.com to find out more about our community development, education and outreach programs.

Technical Details of the Ixtaca Drilling Program

The Main Ixtaca and Ixtaca North Zones of veining are interpreted to have a north-easterly trend. Holes to date suggest that the Main Ixtaca and Ixtaca North Zones are sub vertical with local variations. This interpretation suggests that true widths range from approximately 35% of intersected widths for a -70 degree hole to 94% of intersected widths for a -20 degree hole. The drilling completed to date has traced mineralisation over 1,000 meters along this northeast trend. The Chemalaco (Northeast Extension) Zone strikes roughly north-south (340 azimuth) and dips at 55 degrees to the west. This interpretation suggests that true widths range from approximately 82% of intersected widths for a -70 degree hole to 99% of intersected widths for a -40 degree hole. The orientation of the new vein zone intersected in the holes reported today is not well understood and true widths cannot be calculated at this time.

Mr. Norm Dircks, P.Geo., a qualified person ("QP") under the meaning of NI 43-101, is the QP and project manager of Almaden's Ixtaca program and reviewed the technical information in this news release. The analyses reported were carried out at ALS Chemex Laboratories of North Vancouver using industry standard analytical techniques. For gold, samples are first analysed by fire assay and atomic absorption spectroscopy ("AAS"). Samples that return values greater than 10 g/t gold using this technique are then re-analysed by fire assay but with a gravimetric finish. Silver is first analysed by Inductively Coupled Plasma - Atomic Emission Spectroscopy ("ICP-AES"). Samples that return values greater than 100 g/t silver by ICP-AES are then re analysed by HF-HNO3-HCLO4 digestion with HCL leach and ICP-AES finish. Of these samples those that return silver values greater than 1,500 g/t are further analysed by fire assay with a gravimetric finish. Intervals that returned assays below detection were assigned zero values.

Blanks, field duplicates and certified standards were inserted into the sample stream as part of Almaden's quality assurance and control program which complies with National Instrument 43-101 requirements.

Cautionary Note concerning estimates of Measured, Indicated and Inferred Mineral Resources

This news release uses terms that comply with reporting standards in Canada and certain estimates are made in accordance with Canadian National Instrument 43-101 ("NI 43-101"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes Canadian standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ significantly from the requirements of the U.S. Securities and Exchange Commission ("SEC"), and mineral resource information contained herein may not be comparable to similar information disclosed by United States companies.

This news release uses the terms "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" to comply with reporting standards in Canada. We advise United States investors that while such terms are recognized and required by Canadian regulations, the SEC does not recognize them. United States investors are cautioned not to assume that any part or all of the mineral deposits in such categories will ever be converted into mineral reserves under SEC definitions. These terms have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. Therefore, United States

investors are also cautioned not to assume that all or any part of the "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" exist. In accordance with Canadian rules, estimates of "inferred mineral resources" cannot form the basis of pre-feasibility or other economic studies. It cannot be assumed that all or any part of the "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" will ever be upgraded to a higher category.
