ALMADEN INFILL HOLE HITS 28.95 M OF 5.61 G/T GOLD AND 19.7 G/T SILVER BENEATH PFS PIT

Almaden Minerals Ltd. (“Almaden” or “the Company”; TSX: AMM; NY SE American: AAU) is pleased to

announce new assay results from Almaden’s ongoing exploration a nd development program at the Company’s

Tuligtic project, Mexico. Today’s results are from holes TU-17-532 (infill), and GMET-17-13 and 14 (metallurgical

holes) all drilled into the northeast striking Chemalaco Zone o n the east side of the Ixtaca deposit and the Pre-

Feasibility Study (“PFS”) pit. Ho les TU-17-532 and GMET-17-14 were drilled beneath the PFS pit. These latest

results confirm a high-grade zone of mineralisation immediately outside and beneath the PFS pit and the potential

for expansion of the PFS mine plan. Highlights include the following intercepts:

J.D. Poliquin, chairman of Almaden stated, “We are very encouraged to be further defining the mineralised zone

beneath the PFS pit. It demonstrates the potential for the Ixtaca mine plan to grow. Ongoing drilling will continue

to seek more such zones even as the engineering work and feasibility study progress.”

About the Ixtaca Deposit Feasibility Program

The Company has selected independent engineers Moose Mountain T echnical Services (“MMTS”) to lead the

feasibility study. Various feasibility-related programs are currently underway, including:

 Feasibility-level engineering design;

 Additional geotechnical evaluatio ns in areas of infrastructure and pit slope;

 Continued monitoring of water quality and flow;

 Metallurgical test work to furt her refine the process flowsheet;

 The Comisión Federal de Electricidad (CFE), the state-owned el ectric utility of Mexico, has confirmed the

availability of power from its substation located 27 km from the Ixtaca Project;

 Assessment of contractors suitable to complete site access roa d improvements required for the mine

construction.

About the Ixtaca Drilling Program and the Ixtaca Zone

The Ixtaca Zone is a blind discovery made by the Company in 201 0 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 30 kilometres from an industrial park with rail service where significant manufacturers such as Kimberly

Clarke have facilities. Any pot ential mining operation at Ixtaca would be located in an ar ea previously logged or

cleared with negligible to no current land usage.

The Company has access to the entire project area and works clo sely with local officials and residents. The

Company has employed roughly 70 people in its exploration progr am 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 drill rigs being used at the project. The Company has imple mented a comprehensive science based and

objective community relations and education program for employe es 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 pos sible development scenarios that could evolve

from the feasibility study work are properly understood and com municated throughout the course of the

Company’s exploration and development program. To better explai n 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.

On December 12, 2017 Almaden announced the completion of a Social Impact Assessment (“SIA”) of the Ixtaca

Project completed by Juan-Pablo Gudiño of GMI Consulting (“GMI” ). GMI is a Mexico City-based group which

provides social and environmental consulting services to government and industry. In 2015 it was recognized by

Consulting Magazine as one of the 50 most important consulting companies in Mexico. The work to complete the

SIA was carried out by an interdisciplinary group of nine anthropologists, ethnologists and sociologists graduated

from various universities, who lived in community homes within the Focus Area during the study to allow for

ethnographic immersion and an appreciation for the local custom s and way of life. The SIA sought voluntary

participation from broad, diverse population groups, with specific attention to approximately one thousand persons

in the Focus Area. Key points regarding the study include the following:

 GMI found that Almaden Minerals’ consultation process complies with the Equator Principles and

International Best Practices;

 All the fieldwork is backed up by audio, privacy notices, and photographs which demonstrate the voluntary

participation of the interviewees, and their consent to be included in the study;

 The SIA included the participat ion of men, women, the elderly, boys and girls;

 The SIA concluded that Almaden Minerals had consulted widely w ith the Focus Area communities, the

Ixtaca project was well understood, and that the SIA itself was successful in providing people with an

opportunity to clearly express their views on the impacts of Ixtaca project development.

Technical Details of the Ixtaca Drilling Program

The Main Ixtaca and Ixtaca North Zones of veining are interpret ed to have a north-easterly trend. Holes to date

suggest that the Main Ixtaca and Ixtaca North Zones are sub ver tical with local variations. This interpretation

suggests that true widths range from approximately 35% of inter sected widths for a -70 degree hole to 94% of

intersected widths for a -20 degree hole. The drilling complete d to date has traced mineralisation over 1,000

meters along this northeast trend. The Chemalaco (Northeast Ext ension) 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 orientations of the new vein zones intersected in the holes reported today are not well understood and true

widths cannot be calculated at this time.

The Ixtaca gold-silver deposit is largely comprised of zones of abundant high grade epithermal veins with low

base metals hosted in barren limestone. Gold and silver in these veins occurs largely as electrum (an alloy of gold

and silver) and other leachable sulphides. The boundaries of th ese vein zones, or swarms, with un-mineralised

limestone are well defined both visually and by assay results and are therefore readily modelled for geologic and

resource purposes. The many individual veins and veinlets within the vein swarms branch and re-connect, as well

as locally change strike and dip, pinch and swell. The wirefram e models constructed to define the overall vein

zones therefore contain interspersed irregular zones of barren limestone wallrock. This inclusion of limestone

dilution in the vein zone wireframes results in average reserve grades of 1.17 g/t AuEq (80.5 g/t AgEq), as reported

in the Company’s Pre-Feasibility Study which was filed on SEDAR in May, 2017 (the “PFS”). Nevertheless, the

actual occurrence of gold and s ilver in the limestone hosted Ma in Ixtaca Zone is in the form of high grade veins

and veinlets, not, for example, as widespread low grade dissemi nated mineralisation. These geologic and

mineralogic observations have very positive mining and recovery implications as defined in the PFS released by

the Company:

 The near surface occurrence and broad nature of the Ixtaca gol d-silver deposit vein zones allow for low-

cost bulk open pit mining as opposed to expensive underground m ethods often required for narrow

individual veins. At the time of future mining, the exposure of the vein system on mine benches may allow

for the visual definition between limestone waste and epithermal veining and improvement to the geologic

model from that generated from exploration drill holes. An impr oved mine bench scale geologic model,

along with appropriate ore control systems, may allow for more selective mining and waste definition of

the vein swarms;

 The contrast between barren lim estone and the non-refractory g old and silver ore and vein mineralogy

allows for simple bulk gravity and flotation to remove the barr en limestone to create low mass pull and

volume concentrates. The PFS demonstrates that a bulk flotation concentrate of gravity tails over the

mine life will average approximately 4.3 g/t gold and 390 g/t silver with a mass pull of ~8%;

 Leaching these limestone domain concentrates results in very h igh overall gold and silver recoveries (both

average approximately 90%) into doré on site without the need for expensive smelting as is the case for

many base metal rich precious metal deposits.

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 a bsorption 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-A ES are then re analysed by HF-HNO 3-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.
