Almaden Discovers High Grade Mineralisation in a Previously Undrilled Area Inside the PFS Pit and Confirms Ixtaca North Zone

Hits 10.50 Meters of 3.54 g/t Gold Plus 306.9 g/t Silver as Well as 0.70 Meters of 22.30 g/t Gold Plus 2600.0 g/t Silver

VANCOUVER, BC--(Marketwired - August 23, 2017) - Almaden Minerals Ltd. ("Almaden" or "the Company") (TSX: AMM) (NYSE American: AAU) (NYSE MKT: AAU) is pleased to announce new assay results from Almaden's ongoing exploration and development program at the Company's Tuligtic project, Mexico. Results reported today are from drill hole TU-17-504 drilled on section 10+650 East. This hole intersected significant mineralisation in an upper portion of the PFS pit which was modelled as waste material in the Company's Pre-Feasibility study (74.5 meters grading 0.66 g/t Au and 45.1 g/t Ag). Hole TU-17-504 also further demonstrated the potential for high grade veins within the Ixtaca North Zone (see plan and section maps attached). Highlights include the following intercepts:

Hole TU-17-504  SECTION 10+650 EAST Az. 150, Dip -65 
74.50 meters @ 0.66 g/t Au and 45.1 g/t AgIxtaca North Zone
  Including 19.00 meters @ 1.19 g/t Au and 121.2 g/t AgIxtaca North Zone
  And 3.75 meters @ 1.23 g/t Au and 95.5 g/t AgIxtaca North Zone
64.30 meters @ 0.79 g/t Au and 74.4 g/t AgIxtaca North Zone
  Including 3.45 meters @ 1.58 g/t Au and 97.4 g/t AgIxtaca North Zone
  And 10.50 meters @ 3.54 g/t Au and 306.9 g/t AgIxtaca North Zone
46.85 meters @ 0.49 g/t Au and 68.6 g/t AgIxtaca North Zone
  Including 0.70 meters @ 22.30 g/t Au and 2600.0 g/t AgIxtaca North Zone

The mineralisation reported today confirms the importance of the emerging Ixtaca North Zone, and demonstrates the potential to convert what is currently classified as waste to ore-grade material through continued drilling in the area of the Ixtaca North zone. The Ixtaca deposit 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 Main 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.

J.D. Poliquin, chairman of Almaden stated, "While we have established Ixtaca as a prominent new discovery of gold and silver reserves, we are clearly only at the beginning of the discovery cycle at this project. Ongoing drilling in areas within and proximal to the PFS pit will provide very useful input into the continuing work to deliver a feasibility study early next year, and will begin the process of testing new targets on the Tuligtic claim."

About the Ixtaca Deposit Feasibility Program

The Company has selected independent engineers Moose Mountain Technical Services ("MMTS") and Knight Piesold Ltd. ("KP") to prepare a feasibility study. Various feasibility-related programs are currently underway, including:

  • Feasibility-level engineering design;
  • Additional geotechnical evaluations in areas of infrastructure and pit slope;
  • Continued monitoring of water quality and flow;
  • Metallurgical test work to further refine the process flowsheet;
  • The Comisión Federal de Electricidad (CFE), the state-owned electric utility of Mexico, has confirmed the availability of power from its substation located 27 km from the Ixtaca Project. CFE has been engaged to complete engineering studies required to deliver power;
  • Assessment of contractors suitable to complete site access road 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 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 30 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 drill rigs being used at the project. 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 feasibility study work 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 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.

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.
