Almaden's Elk Project, BC Delivers Positive Preliminary Economics

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 24, 2011) - Almaden Minerals Ltd. ("Almaden" or "the Company") (TSX:AMM)(NYSE Amex:AAU) is pleased to report the results of a positive Preliminary Economic Assessment ("PEA") of the open pit potential of its 100% owned Elk gold project located in British Columbia, Canada. The Positive PEA demonstrates the potential that a viable project could be launched on the Elk property. The results for the base case (at US$1,000 per troy ounce) indicate a mining project with a 7 year mine life producing 139,000 ounces of gold at estimated cash operating costs of $C528 per troy ounce, initial capital expenditures of C$9.91 MM, pre-tax Internal Rate of Return of 51%, payback of 1.85 years and NPV of $C28.7 MM using a discount rate of 8%. The results for US$1,200 per troy ounce case indicate a mining project with a 9 year mine life producing 297,000 ounces of gold at estimated cash operating costs of $C652 per troy ounce, initial capital expenditures of C$17.5 MM, pre-tax Internal Rate of Return (IRR) of 39%, payback of 3.3 years and NPV of $C67.9 MM using a discount rate of 8%.

J.D. Poliquin, Chairman of Almaden commented, "The new positive PEA clearly demonstrates the possible economic viability of the Elk deposit's bulk tonnage potential. We look forward to incorporating the 2010 drill results into this analysis as we move forward in developing the Elk deposit utilising the recommendations of the report. SRK's analysis confirms Elk as a project with solid economics and capable of producing gold with good cash costs. Exploration results at Elk have continued to demonstrate significant growth potential as each additional exploration campaign is conducted. We view the PEA as an excellent foundation and consider it the starting point for Elk which we anticipate will continue to grow in size."

The NI 43-101 compliant PEA was completed by Roger Pooley, (MAusIMM) of SRK Consulting Australasia Pty Ltd. ("SRK"). SRK relied on other authors in the areas of Geology, Resources, and Mineral Processing. Susan Lomas, P.Geo of Lions Gate Geological Consulting ("LGGC") prepared an updated National Instrument 43-101 compliant resource. Gary Hawthorn, P.Eng. of Westcoast Mineral Testing Inc. (WCMT) supervised the metallurgical testing and estimated the preliminary capital and operating costs for a treatment plant. Brian Alexander, P.Geo. supervised the 2010 drilling program at Elk. A Technical Report entitled "NI 43-101 Technical Report for a Preliminary Economic Assessment on the Elk Gold Project, Merrit, British Columbia, Canada" dated January 14th, 2010 will be filed at The experts listed above have written sections of this Technical Report and are acting as the Qualified Person (QP) for those sections.

The PEA did not consider the underground potential of the resource but only the portion of the current resource amenable to open pit mining. The 2010 Mineral Resource Estimate and the PEA study do not include the results of the 2010 drilling at The Company plans to incorporate the 2010 drilling results into an updated mineral resource estimate once all the assay results are received, for the purposes of more advanced studies, including an analysis of the underground potential. The PEA recommends that the Company proceed with a Pre Feasibility Study of the project.

Highlights of the Preliminary Economic Assessment:

- Average life of mine cash operating cost of $C528 per ounce at $US 1,000 per ounce (Base Case) and $C 652 at $US1,200 per ounce.

- Estimated start-up capital expenditures of $C9.91 million and life of mine sustaining capital of $C12.18 million (Base Case).

- At $US1,000 per ounce, pre-tax Internal Rate of Return (IRR) of 51%, payback of 1.85 years and NPV of $C28.7 MM using a discount rate of 8% (Base Case).

- At $US1,200 per ounce gold, pre-tax Internal Rate of Return (IRR) of 39%, payback of 3.3 years and NPV of $C67.9 MM using a discount rate of 8%.

Economic Parameters and Constraints for the Preliminary Economic Assessment:

The preliminary assessment includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary assessment will be realized. This mining study and PEA are at a conceptual level where different options can be considered and a broad understanding of the potential project performance can be gained. SRK and Almaden consider this project to be preliminary or "green field" in nature as previous mining activity on the property was largely for exploration purposes and the property has not been the subject of a detailed pre-feasibility study as is defined in NI 43-101. For the base case pit scenario 9% of the resource considered viable in the study are Measured Resources, 73% Indicated and 18% Inferred Resources. For the US$1200 pit scenario 7% of the resource considered viable in the study is based on Measured Resources, 71% on Indicated and 22% on Inferred Resources.

The trial open pit operation that occurred in the 1990s mined a small portion of vein material. The scenario developed as a recommendation for further study is summarised in the following table. Known as the Base Case, it is based on using augmented process equipment that Almaden already owns. This limits the throughput to 500 tpd. The Base Case is a conservative and low risk scenario in the light of the current gold price, and in practice the project could be expanded to mine a much larger part of the known resources if current gold prices are sustained. To show the effect of this, an alternative case known as the $US1200 case was also studied. The $US1200 case assumes that a gold price of $US1200/tr.oz will be maintained for eight years. The mine processing plant production is doubled, to 1,000 tpd. The underground resources declared in Table 3 below are not considered for production in this report. It is believed that if the project proposed goes ahead, then these resources will have a much improved chance of being mined, because access can be gained from within the open pit, and the treatment plant will have been built, and will be ready to accept underground production without further capital expense. This matter can therefore safely be left for consideration at a later time.

Highlights of Updated Mineral Resource Estimate:

A mineral resource for the Elk Property was estimated by LGGC. Multiple quartz veins were interpreted on north-south trending cross sections. Three-dimensional solids models were built from the sectional interpretations using diamond drill hole data captured through to 2007. Assay gold grades were capped and composited to vein width composites averaging about 1.5 m. Gold grades were estimated into a block model using the inverse-distance method.

LGGC directed SRK to produce a pit shell that LGGC incorporated into the resource estimation tabulations using a $US1200 gold price to constrain the blocks into open pit amenable resources reported at a 0.5 g/t Au cut-off. The remaining resources, that may have potential for underground extraction, was reported at a 5.0 g/t Au cut-off and are located below the $US1200 pit shell. Table 3 reports the results of the mineral resource estimation for the B and WD Veins using data available from December 2007.

Property Location and History:

The Elk Property is located in southern British Columbia, Canada roughly 325 km northeast of Vancouver and 55 km west of Okanagan Lake, approximately midway between the towns of Merritt and Peachland. The property is within the Similkameen Mining District and consists of 27 contiguous mineral claims and one mining lease covering 16,566 hectares. Except for the Agur Option block, Almaden has a 100% interest in all claims. A 1% NSR production royalty is payable on production from the Agur Option block, located approximately 4 km south of the area of estimated resources, and is not relevant to this report. Prospecting activities date back to the early 1900s but detailed work in the area began in 1960s and 1970s by several companies who focused on copper and molybdenum. Fairfield Minerals investigated the area for gold in 1986. Approximately 51,500 ounces of gold were produced between 1992 and 1995 from a test pit and underground mining exploration (a decline was excavated for underground drilling activity, but no stoping or underground mining occurred). Almaden Resources Ltd. amalgamated with Fairfield Minerals in 2002 to form Almaden Minerals (Almaden), which thereby became the sole owner of the Elk gold property and has continued exploration activity on the project since this time.

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, 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 and copper deposits as evidenced at Ixtaca. Currently six projects (Caldera, Caballo Blanco, Tropico, Nicoamen River, Matehuapil and Merit), are optioned to separate third parties who each have the right to acquire an interest in the respective project from Almaden through making certain payments and exploration expenditures. Four further projects are held in joint ventures. Almaden also holds a 2% NSR interest in 11 projects. 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 capital 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.
