VANCOUVER, BRITISH COLUMBIA–(Marketwired – May 6, 2013) – Almaden Minerals Ltd. (“Almaden” or “the Company”) (TSX:AMM)(NYSE MKT:AAU) is pleased to announce results from the first two holes of the 2013 drill program on the Company’s 100% owned El Cobre copper-gold porphyry project, Mexico. This new drilling was conducted on only one of the four porphyry targets identified over a 12 square kilometre area on the project. These new results continue to show the potential of the El Cobre project to host an economic copper-gold porphyry deposit.

J.D. Poliquin, Chairman of Almaden commented, “This new drilling at El Cobre further highlights the potential of this project to host a porphyry deposit. The project has unparalleled infrastructure that is permissive for a deposit to be developed. At this time we have only tested one of four known targets. Much more work is required to fully understand and explore this exciting copper-gold project. While market conditions require us to focus on our Tuligtic project in the near-term, we are looking forward to advancing El Cobre with the aggressive drill program required to explore this tremendous target.”

Highlights from the holes released today include the following intercepts (a more complete list of intercepts is shown in the table below):

Drillhole EC-13-004 was drilled at a -50 degree dip towards the southwest and the intervals reported above and in the table below represent length down the hole. The Company has yet to collect sufficient data to determine how the downhole drill intervals might relate to the actual true thickness of mineralization. Drillhole EC-13-005 was also drilled to the southwest from the same pad but at a steeper angle (-72) and largely intersected intensely phyllic altered and pyrite mineralised monzonite intrusives with minor copper and gold. Hole EC-13-005 is interpreted to not have gone deep enough to cross the significant copper-gold intersection in the shallower EC-13-004. Due to market conditions the Company has temporarily suspended drilling at El Cobre to focus on the Ixtaca zone of its flagship gold-silver Tuligtic project, also in Mexico. Drilling will recommence after the Company has planned a new program of drilling based on an analysis of the holes reported today. Below are plan maps and a relevant section which will be posted to the Company’s website (www.almadenminerals.com).

About the El Cobre Project

Almaden’s 100% owned El Cobre project, currently subject to a 0.5% NSR, is situated about 75 kilometers north of the port city of Veracruz, Mexico. The project is located in an area of unparalleled infrastructure and is located near a power plant and highway. Almaden’s roughly 7,500 hectare claim block covers copper-gold porphyry mineralization known to exist over a strike length of at least four kilometers. Drilling by Almaden and past partners along this strike length has returned significant copper and gold values. Many of the past drill holes on the El Cobre property are shallow and end in copper-gold mineralization. Porphyry mineralization is associated with the exposed portions of diorite stocks which have intruded intermediate volcanic rocks. Mineralogic and fluid inclusion studies show conclusively that the gold and copper-gold porphyry-style mineralization at El Cobre is not deeply eroded and great potential exists at depth.

Mr. Norm Dirks, P.Geo., a qualified person (“QP”) under the meaning of NI 43-101, is the QP and project manager of Almaden’s El Cobre drilling program and reviewed the technical information in this news release. The attached table contains analyses from past programs conducted by Almaden and former joint venture partners. Analyses reported from current and past drilling conducted by Almaden were carried out at ALS Chemex Laboratories of North Vancouver using industry standard aqua regia, ICP and fire assay techniques. This sampling also included a quality control program and the insertion of field duplicates, certified standards and blanks into the sample stream. Analyses reported from past drilling conducted by past partners cannot be verified by Almaden but are believed to have been acquired from exploration programs carried out under the supervision of qualified persons (under the meaning for qualified person as defined in NI 43-101) and in accordance with NI 43-101 requirements.

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.
