ALMADEN ACQUIRES NEW GOLD-SILVER PROJECT ALONG IXTACA TREND

Almaden Minerals Ltd. has acquired a 100-per-cent interest in the approximately 10,000-hectare Tierra property through staking. The Tierra property is also located in Puebla state, roughly 30 kilometres from Almaden's 100-per-cent-owned Tuligtic project where the company recently announced a significant drilling discovery at the Ixtaca zone (see Almaden news release of Aug. 9, 2010, in Stockwatch; TU-10-1 intersected 1.01 grams per tonne gold and 48 g/t silver over 302.41 metres).

The Tierra project covers a broad area of intense clay and silica alteration developed in volcanic rocks which overlie deformed Cretaceous carbonate units. Stream sediment samples taken by Almaden have returned anomalous arsenic, antimony and mercury values. This geological setting interpreted to be very similar to that at the Ixtaca zone represented the shallow portions of a well-preserved epithermal system.

The acquisition of the Tierra project adds to Almaden's portfolio of properties in central Mexico, which includes the 100-per-cent-Almaden-owned Caldera and Lajas properties, both acquired through staking. The Ixtaca, Caldera, Tierra and Lajas properties are located near or within the Trans Mexican volcanic bell, and all are less than 150 kilometres from the Pachuca gold/silver deposit which has reported historic production of 1.4 billion ounces of silver and seven million ounces of gold. The Ixtaca zone is a drilling discovery beneath barren kaolinite and silica alteration. The Caldera project is located roughly 10 kilometres from the Ixtaca zone and covers an area of intense acid-sulphate alteration including zones of massive to vuggy silica, quartz-alunite and kaolinite over an eight-kilometre-by-two-kilometre area. Rock samples taken to date in areas of acid sulphate alteration have returned values from below detection to 40 parts per billion gold. High values of arsenic and mercury were also returned in this sampling program. Almaden's management believes that the Caldera project represents a well-preserved high-sulphidation system. The Lajas project covers outcropping quartz veins that were identified in a regional exploration program. Three reconnaissance rock grab and chip samples taken by Almaden returned an average of 3.2 g/t gold and a high of 9.3 g/t gold over a 0.3-metre width. Recent soil sampling at Lajas has outlined a broad area of anomalous gold and trace-metal elements consistent with epithermal mineralization.

J.D. Poliquin, chairman of Almaden, commented: "The Caldera, Lajas and recently acquired Tierra projects are a testament to our ongoing prospect-generation efforts. All three, while early stage, cover large underexplored alteration zones. Our recent Ixtaca discovery shows that such targets have the potential to host significant mineralization. As Almaden plans to focus on the Ixtaca zone and its JV [joint venture] El Cobre porphyry-copper-gold project in Veracruz state, the company seeks qualified and technically proficient partners with whom to jointly explore the Caldera, Lajas and Tierra projects."

Morgan J. Poliquin, PhD, PEng, the president and chief executive officer of Almaden and a qualified person under the meaning of National Instrument 43-101, reviewed the technical information in this news release. The analyses reported were carried out at ALS Chemex Laboratories of North Vancouver using industry-standard aqua regia, ICP and fire-assay techniques.
