Vancouver, December 5, 2012 --PMI Gold Corporation ("PMI") (TSX: PMV, ASX: PVM, Frankfurt: PN3N.F) and Keegan Resources Inc. ("Keegan") (TSX, NYSE MKT: KGN) are pleased to announce that today they have entered into a definitive arrangement agreement to combine their respective businesses (the "Merger") and to create a leading West African gold development company. A joint conference call hosted by Peter Breese and Collin Ellison will be held at 4:30 pm (EST) and 1:30 pm (PST) today (8:30 am Thursday in Sydney) to discuss this transaction. Call-in details are provided at the end of this release.

The combined company will continue under the name "Asanko Gold Inc." ("Asanko"), reflective of the West Ghana region in which the two companies hold their principal gold projects. Asanko will be led by Peter Breese, the current President and CEO of Keegan and Collin Ellison, the current Managing Director and CEO of PMI. Under terms of the Merger (which will be effected by means of a statutory plan of arrangement of PMI), each PMI shareholder will receive 0.21 Asanko shares for each PMI share (the "Exchange Ratio"). As Keegan is the surviving corporate entity, existing Keegan security holders will not need to exchange their securities in the Merger. The Merger will create a combined company with an aggregate market capitalization expected to be in the $700 million range. Existing Keegan and PMI shareholders will each own approximately 50% of the combined company, inclusive of currently in-the-money dilutive securities.

HIGHLIGHTS OF THE MERGER

Asanko is set to become the leading gold development company in West Africa with near term production expected from a unitized project comprised of two nearby gold deposits -- Obotan and Esaase. Other merger highlights include:

• Measured and Indicated Resources of combined projects = 6.94 million ounces at an average grade of 1.90 grams per tonne^1,2,3 ;
• Additional Inferred Resources of combined projects = 2.65 million ounces at an average grade of 1.87 grams per tonne^1,2,3 ;
• Strongly capitalized with over $340 million in cash on hand and no debt outstanding;
• Obotan can proceed to construction quickly -- approximately 200,000 ounces per year with first gold pour expected in 2014;
• Esaase development to be funded from cash flow -- additional 150,000 to 200,000 ounces per year by 2017;
• Targeted operational and capital synergies through a 2013 optimization analysis - Obotan and Esaase located within a 15 km radius;
• Experienced mine development and operational executive and management team to build and operate;
• Consolidated Asankrangwa gold belt -- over 70 km of belt strike anchored by the Obotan and Esaase deposits and over 1,000 square kilometers in Ghana;
• Planned growth through exploration of numerous high priority targets on the belt as well as Kubi and Asumura;
• Enhanced capital markets presence -- Asanko is expected to appeal to a broader shareholder base, increase analytical following and improved share trading liquidity;
• Merger is expected to be tax neutral or deferred for substantially all participants; and
• Asanko shares issued to PMI shareholders under the Merger will be free of trading restrictions in Canada and United States (except for affiliated persons); Asanko shares are required to be listed on the TSX, ASX and NYSE MKT Equities Exchange upon completion of the Merger.

Peter Breese, President and CEO of Keegan, stated: "This is truly a unique and exciting opportunity to combine these two adjacent and near-term development projects and to have available some $340 million in combined cash to fund a Mid-Tier scale production growth profile starting in about two years. We expect significant synergies through the joint development of Obotan and Esaase which we expect will ultimately create one of the largest gold mining and exploration districts in Africa."

Collin Ellison, Managing Director and CEO of PMI, stated: "We think the combination of these two companies with adjacent and complementary deposits, highly prospective exploration holdings on the Asankrangwa belt, outstanding self-funding financial flexibility and a combined management strength will allow both groups of shareholders to realize maximum value through Asanko Gold's path to production and aggressive growth profile through to Mid-Tier Producer status by 2017."

MANAGEMENT TEAM AND BOARD OF DIRECTORS

The Board of Directors and management of Asanko will draw from the expertise of both companies. Peter Buck and Shawn Wallace, the respective Chairmen will become Co-Chairmen, while Peter Breese will become Chief Executive Officer and Collin Ellison will become Asanko's President. Other senior management will be determined following completion of the Merger.

On immediate completion of the Merger, the Board will be comprised of three directors from each predecessor and a seventh director will be added post-completion. The initial six directors of Asanko will be, from PMI: Peter Buck, Ross Ashton and John Clarke; and from Keegan: Shawn Wallace, Colin Steyn and Gord Fretwell.

DETAILS OF THE ARRANGEMENT AGREEMENT

The proposed Merger will be effected by way of court-approved plan of arrangement of PMI (the "Arrangement") under the Business Corporations Act of British Columbia. Full details of the Merger will be included in joint management information circulars for both PMI and Keegan which will be mailed to their respective shareholders in late January 2013. The Merger will be subject to approval of 50% plus one of the votes cast by Keegan shareholders and by 2/3 of the votes cast by PMI shareholders at their respective special meetings of shareholders which will both be held on the same day targeted for late February, 2013. In addition to the shareholder approvals and a court approval, the Merger is subject to applicable regulatory approvals and the satisfaction of other customary closing conditions, including Asanko obtaining an ASX listing for its shares. A copy of the arrangement Agreement will be posted at www.SEDAR.com and a summary will be included in the joint information circular.

Pro-forma the Arrangement, Asanko will have approximately 171.7 million shares outstanding, 11.4 million options outstanding and 9.8 warrants outstanding. PMI options and warrants will be cancelled and replaced by equivalent length options and warrants of Asanko which will be adjusted as to number and exercise based on the Exchange Ratio. Pro-forma ownership of Asanko is approximately 50% PMI and 50% Keegan including currently in-the-money dilutive securities.

Asanko will maintain its TSX and NYSE MKT listings, and will forthwith apply to list on the ASX subject to completion of the Merger. In the United States the issuance of securities of Asanko under the Merger will be conducted in reliance on the exemption from registration found under section 3(a)(10) of the Securities Act of 1933. Asanko will continue to be a foreign private issuer under United States securities laws.

The Arrangement Agreement includes mutual deal protection provisions, including no solicitation obligations, right to match, a mutual $13 million break fee and customary fiduciary-out provisions in the event of a superior proposal being received by either company.

Both companies' Boards of Directors have determined that the proposed business combination is in the best interests of their respective shareholders based on a number of factors, including verbal fairness opinions received from each of their respective financial advisors. These opinions are subject to certain assumptions and limitations and opine on the fairness, from a financial point of view, of the consideration to be received by their respective shareholders pursuant to the Merger. These factors will be further discussed in the joint information circular. Each company's Board of Directors has unanimously approved the terms of the proposed Merger and will recommend that their respective shareholders vote in favour of the Merger at their respective shareholder meetings. In addition, directors and officers of both companies have entered into voting lock-up agreement to vote in favour of the Merger.

Cautionary Note Regarding Forward-Looking Statements and Information:

This PMI and Keegan joint press release contains "forward-looking information", as such term is defined in applicable Canadian securities legislation and "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995. Such statements concern PMI's and Keegan's future financial or operating performance and other statements that express management's expectations or estimates of future developments, circumstances or results. Generally, forward-looking information can be identified by the use of forward-looking terminology such as "expects", "believes", "anticipates", "budget", "scheduled", "estimates", "forecasts", "intends", "plans" and variations of such words and phrases, or by statements that certain actions, events or results "may", "will", "could", "would" or "might", "be taken", "occur" or "be achieved". Such forward-looking information may include, without limitation, statements regarding the completion and expected benefits of the proposed Merger and other statements that are not historical facts. Forward-looking information is based on a number of assumptions and estimates that, while considered reasonable by management based on the business and markets in which PMI and Keegan operate, are inherently subject to significant operational, economic and competitive uncertainties and contingencies. Assumptions upon which forward looking statements relating to the plan of arrangement have been made include that PMI and Keegan will be able to satisfy the conditions in the Arrangement Agreement, that ongoing due diligence investigations of each party will not identify any materially adverse facts or circumstances, that the required approvals will be obtained from the shareholders of each of PMI and Keegan, that all required third party, and that regulatory and government approvals will be obtained. PMI and Keegan caution that forward-looking information involves known and unknown risks, uncertainties and other factors that may cause PMI's and Keegan's actual results, performance or achievements to be materially different from those expressed or implied by such information, including, but not limited to: gold price volatility; fluctuations in foreign exchange rates and interest rates; between actual and estimated reserves and resources or between actual and estimated metallurgical recoveries; costs of production; capital expenditure requirements; the costs and timing of construction and development of new deposits and expansion of existing operations; the success of exploration and permitting activities; parts, equipment, labor or power shortages or other increases in costs; mining accidents, labour disputes or other adverse events; and changes in applicable laws or regulations.

There can be no assurance that such information will prove to be accurate or that management's expectations or estimates of future developments, circumstances or results will materialize. As a result of these risks and uncertainties, the proposed Merger could be modified, restricted or not completed, and the results or events predicted in these forward looking statements may differ materially from actual results or events. Accordingly, readers should not place undue reliance on forward-looking information. The forward-looking information in this press release is made as of the date of this press release, and PMI and Keegan disclaim any intention or obligation to update or revise such information, except as required by applicable law and neither Keegan not PMI assume any liability for disclosure relating to the other company herein.
