Almaden Infill Drilling Confirms High-Grade Northern Main Zone, Hits 18.25 Meters of 5.68 G/T Au, 923.8 G/T Ag (24.2 G/T Aueq) at Ixtaca, Mexico

Marketwired

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sep 23, 2013) - Almaden Minerals Ltd. ("Almaden" or "the Company") (AMM.TO) (NYSE MKT:AAU) is pleased to announce the results from Almaden's ongoing 2013 Ixtaca Zone drill program at the Company's 100% owned Tuligtic project, Mexico. Almaden has commenced an infill drilling program with two of the three rigs currently drilling on the project. The infill program has been designed to upgrade resources currently in the inferred category to the higher confidence measured and indicated categories. At the same time one drill rig is focussed on step out drilling to expand the resource. The holes announced today show the continuity of high-grade gold silver veining in the Northern Branch of the Main Ixtaca high grade zone defined with previous drilling. Highlights from the holes released today include the following intercepts (a more complete list of intercepts is shown in the table below):

Hole TU-13-306 NORTHERN MAIN ZONE
89.50 meters @ 1.34 g/t gold and 33.9 g/t silver (2.0 g/t gold equivalent)
Including 6.00 meters @ 12.04 g/t gold and 30.4 g/t silver (12.6 g/t gold equivalent)
Hole TU-13-309 NORTHERN MAIN ZONE
41.20 meters @ 2.84 g/t gold and 429.2 g/t silver (11.4 g/t gold equivalent)
Including 18.25 meters @ 5.68 g/t gold and 923.8 g/t silver (24.2 g/t gold equivalent)
Hole TU-13-313 NORTHERN MAIN ZONE
5.50 meters @ 4.38 g/t gold and 317.9 g/t silver (10.7 g/t gold equivalent)
Hole TU-13-316 NORTHERN MAIN ZONE
33.50 meters @ 1.72 g/t gold and 80.0 g/t silver (3.3 g/t gold equivalent)
Including 17.00 meters @ 2.20 g/t gold and 96.9 g/t silver (4.1 g/t gold equivalent)

J.D. Poliquin, chairman of Almaden stated, "Today's holes show the continuity of high-grade mineralisation in the main part of the deposit. The infill drilling program underway was designed to upgrade the confidence of our resource base. It also provides an opportunity to remind our shareholders that the Ixtaca zone of veining is cored by several well defined and intensely mineralised high grade gold silver zones that have good continuity along strike."

About the Ixtaca Property

The 100% owned Ixtaca zone is a blind discovery made by the Company in 2010. 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. Based upon observations at surface and of core as drilling progresses, there seems to be a variety of veinlet orientations within the Northeast Extension Zone however overall the zone is currently interpreted to be dipping to the west and striking roughly north-south.

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.

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. Gold equivalent ("AuEq" or "Gold Eq.") and silver equivalent ("AgEq" or "Silver Eq.") values were calculated using silver to gold ratios of 50 to 1. The ratio of 50 to 1 was used for the sake of consistency with past news releases. Intervals that returned assays below detection were assigned zero values. Metallurgical recoveries and net smelter returns are assumed to be 100% for these calculations.

About Almaden

Almaden is a well-financed mineral exploration company working in North America. The company has assembled mineral exploration projects, including the Ixtaca Zone and the Tuligtic project, through its grass roots exploration efforts. While the properties are largely at early stages of development they represent exciting opportunities for the discovery of significant gold, silver and copper deposits as evidenced at Ixtaca. Almaden's business model is to find and acquire mineral properties and develop them by seeking option agreements with others who can acquire an interest in a project by making payments and exploration expenditures. Through this means the company has been able to expose its shareholders to discovery and capital gain without the funding and consequent share dilution that would be required if the company were to have developed these projects without a partner. The company intends to expand this business model, described by some as prospect generation, by more aggressively exploring several of its projects including the Ixtaca Zone.
