Almaden Expands Ixtaca and Ixtaca North Zone, Intersects 16.85 m of 1.58 g/t Au and 212.2 g/t Ag (5.8 g/t Aueq)

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 28, 2011) - Almaden Minerals Ltd. ("Almaden" or "the Company") (TSX:AMM)(NYSE Amex:AAU) is pleased to announce results from the on-going drilling at the Ixtaca Zone with holes TU-11-43, 44, 46, 47, 48, 49, 50 and 52 and CA-11-04. Holes TU-11-47, 48 and 52 were drilled 180 degrees away from the known Ixtaca veining (at a 330 azimuth) and intersected a zone of mineralisation now referred to as Ixtaca North, the orientation of which is currently poorly understood. Hole TU-11-43 represents a 100 meter stepout to the northeast along the Ixtaca trend and intersected veining in the ash and its contact with limestone. This mineralisation is interpreted to be leakage from a potential vein system below and will be tested with further drilling, however hole TU-11-43 clearly shows that veining continues along strike and remains open to the northeast. Final assays remain pending for holes TU-11-45 and 51.

Highlights from the current group of assays include the following intercepts:

system is wider than previously known. Drilling to date on the Ixtaca zone also shows good continuity of mineralisation in both horizontal and vertical dimensions. We are very pleased with these new results which further expand the known extent of the Ixtaca zone. We now have three drills on site." The Company anticipates drilling operations will continue throughout 2011. The Company is encouraged with the results to date and intends to expand the drilling project and is currently designing the program and budget.

About the Ixtaca Property

The 100% owned Ixtaca zone is a blind discovery made by the Company in 2010. The zone of veining is thought to have a north-easterly trend. Holes to date suggest that the zone is sub vertical with local variations. This interpretation suggests that true widths are approximately 60% of intersected widths. The drilling completed to date has traced mineralisation over 750 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 vein zone. Registered professional geologist (Utah) Jim Lunbeck, a qualified person ("QP") under the meaning of NI 43-101, is the current 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 (no debt, approximately $C25 MM in working capital) mineral exploration company working in North America. The company has assembled mineral exploration projects, including Tuligtic, 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.
