ALMADEN CONFIRMS NEW ZONE OF HIGH-GRADE MINERALISATION WITHIN PFS PIT
HITS 1.00M OF 237.00 G/T GOLD PLUS 232.0 G/T SILVER
WITHIN 38.60M OF 7.92 G/T GOLD AND 14.9 G/T SILVER (UNCUT)
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. One drill rig is focused on step-out exploration drilling outside of the established resource
area, while the second drill rig has completed holes for metall urgical samples related to the ongoing Feasibility
Study, and is now testing new zones within the Pre-Feasibililty Study (“PFS”) pit. Today’s results are from holes
TU-17-518 and 520 which were drilled to follow-up hole TU-17-504 (announced August 23, 2017) that intersected
new and significant mineralisation in an upper portion of the PFS pit which was modelled as waste material in the
Company’s PFS. Holes TU-17-518 and 520 confirm this discovery of a new zone of mineralisation in volcanic and
limestone. Highlights include the following intercepts:
Hole TU-17-518 SECTION 10+ 650 EAST Az. 150, Dip -57
23.00 meters @ 0.45 g/t Au and 1.0 g/t Ag
38.60 meters @ 7.92 g/t Au (2.84 g/t with 1 sample cut1) and 14.9 g/t Ag
Including 23.50 meters @ 12.70 g/t Au (4.36 g/t with 1 sample cut1) and 20.7 g/t Ag
And 5.00 meters @ 51.45 g/t A u (12.25 with 1 sample cut1) and 58.4 g/t Ag
And 1.00 meters @ 237.00 g/t Au and 232.0 g/t Ag
1 gold assays over 41 g/t were cut to 41 g/t.
Hole TU-17-520 SECTION 10+ 675 EAST Az. 150, Dip -70
20.40 meters @ 0.89 g/t Au and 11.1 g/t Ag
Including 7.00 meters @ 2.07 g/t Au and 20.4 g/t Ag
J.D. Poliquin, chairman of Almaden stated, “These results again show the potential of the Ixtaca gold silver deposit
to grow. As I have stated before, while Ixtaca is a prominent new discovery of gold and silver reserves, we are
clearly only at the beginning of the discovery cycle a t this project. We have a two-pronged approach. On
the one hand we are focussed on developing the Ixtaca deposit i nto a significant precious metals producer in
Mexico, and engineering work and studies on a Feasibility Study are progressing well. At the same time we have
in front of us the opportunity for additional discovery and res ource growth. We are at the top of a fully preserved
epithermal system and over the next several months exploration drilling will also test for additional vein zones
beneath alteration elsewhere on the project.”
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;

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.
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
- 3 -
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.
