VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 22, 2011) - Keegan Resources Inc. ("Keegan" or the "Company) (News - Market indicators)(NYSE Amex:KGN) is pleased to announce the results of its Pre-Feasibility Study ("PFS" or "Study") for its Esaase Gold Project ("the Project") located near Kumasi, in southwestern Ghana, West Africa. All currency is in United States Dollars unless otherwise stated.

A conference call will be held Thursday, September 22nd at 8:00 a.m. (PST), 11:00 a.m. (EST) to discuss the Pre-Feasibility Study. For conference call details please see the end of this release.

Highlights of the PFS are as follows:

• 2.6 million ounces of gold produced over a 10.2 year mine life.
• Plant capacity of 7.5 million tonnes per annum, with capacity to treat 9.0 million tonnes per year in early years of production when processing 100% oxide ore.
• 330,000 oz gold produced in Year 1, with a Life Of Mine (LOM) average of 258,000 oz/yr.
• $639 million after-tax Net Present Value ("NPV") discounted at 5% and an Internal Rate of Return ("IRR") of 32% (100% equity basis at $1,500/oz gold revenue applied to a $1,150/oz gold pit shell).
• Capital cost of $506 million, utilizing a leased mining fleet. Cash costs of $693/oz gold produced including leasing costs for mining equipment (approximately $55/oz).

Infill drilling completed in conjunction with the PFS was used to prepare an updated Mineral Resource estimate with highlights as follows:

• Measured and Indicated Resources: 98.7 million tonnes grading 1.1 g/t gold and containing 3.64 million ounces of gold (lower cutoff grade of 0.4g/t gold).
• Inferred Resources: 45.9 million tonnes grading 1.1 g/t gold and containing 1.55 million ounces of gold (lower cutoff grade of 0.4g/t gold).

Based on the positive results of the PFS, a portion of the Measured and Indicated Mineral Resource was converted to Proven and Probable ("P&P") Mineral Reserves with highlights as follows:

• Total P&P Reserves: 79.4 million tonnes grading 1.1 g/t gold and containing 2.88 million ounces of gold (based on $1,150/oz gold pit shell).

Maurice Tagami, President & CEO of Keegan, commented: "We are very pleased with the results of the Study, which continue to demonstrate a robust project and significant annual gold production over a mine life of 10+ years. With our current cash reserve of $220 million, we feel confident that we can rapidly advance the Project to production."

Keegan is also in the process of advancing its financing strategy in conjunction with the completion of the Definitive Feasibility Study Project (DFS) that is currently underway. Due to the current strong market environment for gold, Keegan's management feels it can negotiate accretive financing options in order to maximize shareholder value and minimize dilution.

The company is also focused on continuing to drill test the numerous prospective targets on the Essase concessions as well as others.

Mr. Tagami added, "We continue to be excited about ongoing exploration sampling and drilling on the B Zone, the Dawahodo concession and the recently acquired Sky Gold concessions."

Pre-Feasibility Study

The Study was completed by Lycopodium Minerals Pty Ltd. ("Lycopodium") and Coffey Mining Pty Ltd. ("Coffey") both of Perth, Australia.

Study Summary

A life of mine study summary is outlined below based on an average gold recovery of 91.3%. The mine plan was developed using a lower cut-off grade of 0.4 g/t and a gold price of $1,150 per ounce.

The initial capital cost of the Project is estimated to be $506 million in first quarter 2011 dollars. Sustaining and deferred capital over the life of mine is estimated at $43 million and is primarily for the subsequent lifts of the tailings impoundment facility and grinding circuit additions for fresh material. Trade-off studies were conducted and it was determined that leasing the mining fleet offered the best return to the Project.

A table summarizing the capital costs is shown below:

Summary Capital Estimate

The capital estimate includes contingency of $53.7 million in the initial capital.

Total direct operating cash costs are estimated at $693 per ounce (excluding royalties and refining charges). Royalties of 5.5% have been accounted for in the economic analysis.

Summary Cash Costs

Economic Analysis

The economic analysis has been completed on a 100% Project basis. Keegan's interest in the Project is the maximum allowable under Ghanaian law and Keegan holds a mining lease for the Project. The lease stipulates a 10% free carried interest of the Project for the government of Ghana and a 5% royalty to the government and a 0.5% royalty to a Liquidation Committee. A corporate tax rate of 25% has been incorporated in the analysis.

A summary of the Project economic analysis post-tax at various gold prices is as follows:

Mineral Resource and Reserve Estimate

Coffey prepared an updated Mineral Resource estimate which incorporated infill drilling conducted subsequent to the previous estimate dated December 2010. The updated Mineral Resource estimate was used as a basis for the Study. 

A summary of the updated Mineral Resource estimate, at a 0.4g/t gold cutoff, is shown below: 

Updated Mineral Resource Estimate Summary

Based on the positive outcome of the PFS, a portion of the Mineral Resource has been upgraded to Mineral Reserves. Only Measured and Indicated Mineral Resources were included in the mine plan for the Study.

The Mineral Reserves are summarized as follows:

Mineral Reserve Estimate Summary

The Mineral Reserve estimate has been based on a cut-off grade of 0.4 g/t gold and a long-term gold price of $1,150 per ounce.

The Mineral Resource and Mineral Reserve estimates have been prepared in accordance with the 2010 CIM Definition Standards for Mineral Resources and Mineral Reserves as incorporated by reference in National Instrument 43-101 of the Canadian Securities Administrators. The Coffey Qualified Persons for the estimates are Brian Wolfe, MAusIMM for Mineral Resources and Harry Warries, MAusIMM for the Mineral Reserves.

As this is a first statement of Mineral Reserves for the Project, Keegan plans on filing a NI 43-101 compliant technical report outlining the Mineral Resource and Reserve Estimate and the results of the PFS. The report will be available on www.sedar.com within 45 days of the date of this press release.

The NI 43-101 technical report will be authored by Brian Wolfe, MAusIMM and Harry Warries, MAusIMM, of Coffey and Chris Waller, MAusIMM of Lycopodium. These independent Qualified Persons have verified the data in this news release. Andrea Zaradic, P.

Forward Looking and other Cautionary Information

This release includes certain statements that may be deemed "forward-looking statements". All statements in this release, other than statements of historical facts, that address estimated resource quantities, grades and contained metals, possible future mining, exploration and development activities, are forward-looking statements. In particular, Preliminary Economic Assessments are preliminary in nature, including 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 findings of the Preliminary Assessment will be realized. Although the Company believes the expectations expressed in the Preliminary Economic Assessment and other forward-looking statements are based on reasonable assumptions, such statements should not be in any way construed as guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Factors that could cause actual results to differ materially from those in forward-looking statements include market prices for metals, the conclusions of detailed feasibility and technical analyses, lower than expected grades and quantities of resources, mining rates and recovery rates and the lack of availability of necessary capital, which may not be available to the Company on terms acceptable to it or at all. The Company is subject to the specific risks inherent in the mining business as well as general economic and business conditions. For more information on the Company, Investors should review the Company's annual Form 20-F filing with the United States Securities Commission and its home jurisdiction filings that are available at www.sedar.com.

Information Concerning Estimates of Measured, Indicated and Inferred Resources

This news release also uses the terms , "measured resources", 'indicated resources' and 'inferred resources'. Keegan Resources Inc. advises investors that although these terms are recognized and required by Canadian regulations (under National Instrument 43-101 Standards of Disclosure for Mineral Projects), the U.S. Securities and Exchange Commission (SEC) does not recognize them. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves as defined by SEC standards. In addition, 'inferred resources' have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for Preliminary Assessment as defined under 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
