NEWS RELEASE

Yamana to Acquire Viceroy Solidifying its
Position as Leading Intermediate Gold Producer

Toronto, Ontario, August 16, 2006 – Yamana Gold Inc. (Yamana) (TSX:YRI; AMEX:AUY; LSE (AIM):YAU) and Viceroy Exploration Ltd. (Viceroy) (TSX: VYE; AMEX:XVE) today announced that Yamana has agreed to make a take-over bid to acquire all of the outstanding common shares of Viceroy in exchange for Yamana common shares. Yamana has agreed to offer Viceroy shareholders 0.97 of a Yamana common share for each Viceroy common share held. Based on today’s respective TSX closing prices of C$11.20 for Yamana and C$8.65 for Viceroy, the transaction value is C$10.86 per Viceroy common share, representing a premium of 25.5% . Based on the 20-Day volume-weighted average of Yamana’s share price, the transaction value is C$11.19 per Viceroy common share, representing a premium of 27.0% over the 20-Day volume-weighted average price of Viceroy’s common shares. Yamana and Viceroy have entered into a support agreement pursuant to which the Board of Directors of Viceroy have unanimously supported the transaction and recommend that shareholders tender their shares to the bid.

The successful completion of the transaction results in Yamana adding a new advanced stage project in a highly prospective exploration district, further solidifying Yamana’s position as a leading intermediate gold producer. Viceroy’s principal asset is the advanced exploration-stage Gualcamayo gold project in San Juan province, Argentina. Yamana, following this transaction, will have the following profile:

Projected annualized production of one million ounces by 2008 up from estimated gold production of approximately 600,000 ounces in 2007 (not including Yamana’s other development stage projects)
Total measured and indicated resources of approximately 11.8 million ounces of gold plus inferred resources of approximately 6.9 million ounces before accounting for the Gualcamayo resource update expected to be completed by the end of August
Proven and probable gold reserves of approximately 7.2 million ounces (included in above measured and indicated resource). This does not include potential mineral reserves at Gualcamayo which are still subject to a planned feasibility study

Proven and probable copper reserves of approximately 2.3 billion pounds
One of the largest Brazilian exploration land holdings with a significant presence in three major gold belts
Addition of the Gualcamayo exploration district in Argentina along with other assets held by Viceroy.

Viceroy is also pleased to announce the assay results from hole number QD-321, which is stepped out over 50 meters to the northwest of hole number QD-309. It returned 118 meters at a weighted-average grade of 2.4 g/t, including 92 meters at 2.6 g/t. Hole number QD-309 had previously returned 129.7 meters of a grade of 2.62 g/t, including 100 meters of 3.23 g/t (See Viceroy release 2006.15 of July 11, 2006). Hole number QD-322 which is stepped out over 50 meters to the southeast of QD-309 is currently in progress. The results from QD-321 corroborate the view that there could be a significant down dip extension of the QDD structure, which is still open along strike.

The transaction provides the following anticipated benefits to Yamana and Viceroy shareholders:

Adds an advanced stage project with a growing resource base
Adds long term gold production and potential from Gualcamayo which is expected to contribute to Yamana’s production goal of one million ounces by 2008
Increases operational strength and management depth through the addition of Viceroy’s team
Leverages Yamana’s mine building expertise derived from constructing the São Francisco and Chapada mines
Utilizes Yamana’s available cash and significant cash flow and lower-cost Brazilian capital cost structure to develop Gualcamayo
Further enhances both companies’ long-term exploration potential
Solidifies Yamana’s positioning among the top intermediate global gold producers
Broadens shareholder base and increases share trading liquidity
Adds projects, currency and country diversification

Yamana believes that a positive feasibility study at Gualcamayo could result in the definition of mineral reserves in the range of two million ounces based on its assessment of the mineral resources and that Gualcamayo could produce 160,000 ounces annually.

This transaction allows Viceroy shareholders to continue to participate in the development of Gualcamayo without facing the risks normally associated with a single-project company. Furthermore, Viceroy shareholders benefit from the exploration and development upside of Yamana’s properties in three major Brazilian gold belts and significant cash flow from its operations.

Delivered on Promises – Extending Our Vision

Peter Marrone, President and Chief Executive Officer of Yamana, said, “In our strategic vision which we developed in late 2005, our goal was to produce one million ounces of gold by 2008. With this acquisition, we will have the assets in place to allow us to meet that goal. The purchase of Viceroy adds

another large-scale, long-life project to Yamana’s existing assets. We expect the planned feasibility study to confirm our expectation of mineral reserves and production levels at Gualcamayo. Yamana’s mine building team is near completion of the Chapada mine and has already successfully commissioned the São Francisco mine. The resulting in-house expertise and lower-cost structure in Brazil will add significant value to the Gualcamayo project. Further, the similarities in proposed mining methods at Gualcamayo and those employed by Yamana should allow for a smooth start-up and operation following completion of a feasibility study and development of Gualcamayo. The addition of Viceroy’s operating management to Yamana will enhance the depth of Yamana’s team and help facilitate the successful development of Yamana’s future projects such as C1 Santa Luz, São Vicente and Ernesto. This transaction solidifies Yamana’s standing among the top tier of intermediate-size global gold producers.”

Patrick Downey, President and Chief Executive Officer of Viceroy, said, “This transaction helps Viceroy achieve its corporate objectives of building Gualcamayo while maintaining significant leverage to the project’s future and other prospective exploration projects, and at the same time achieving an immediate premium along with further valuation upside in Yamana’s shares. Yamana’s team has demonstrated success in integrating management teams and providing significant value appreciation from its previous acquisitions. Viceroy shareholders will continue to have significant upside from Gualcamayo, while participating in the operational and exploration valuation upside from Yamana with reduced risk from the diversification of assets. We are confident that we will continue to benefit from Yamana’s shares as they are one of the most attractively valued global intermediate gold producers.”

Summary of the Transaction

The acquisition of Viceroy will be completed by way of a take-over bid whereby Yamana will offer to acquire each outstanding Viceroy common share in exchange for 0.97 of a Yamana common share. In the event that Yamana acquires 100% of the outstanding shares of Viceroy, the combined company will be held approximately 85% by existing Yamana shareholders and 15% by existing Viceroy shareholders. The total number of Yamana common shares outstanding will be approximately 344.4 million, on a pro forma basis. The transaction values Viceroy at approximately US$515 million on a non-diluted basis.

The acquisition has the unanimous approval of the Boards of Directors of Yamana and Viceroy. The Board of Directors of Viceroy, having received the unanimous recommendation of a Special Committee of Directors, is recommending that holders of Viceroy common shares tender their shares to the Yamana offer. Each of Canaccord Adams and Genuity Capital Markets have provided an opinion to the Special Committee of the Board of Directors of Viceroy that the consideration to be offered to Viceroy shareholders pursuant to the offer is fair, from a financial point of view, to the holders of common shares of Viceroy other than Yamana.

Management and Directors of Viceroy have entered into lock up agreements with Yamana under which they have agreed to tender 3.2 million voting shares representing a 6% interest in Viceroy.

Patrick Downey will join the management of the combined company in the role of Executive Vice President, Operations with the primary responsibility of developing Gualcamayo. Viceroy’s team in Argentina will be joining Yamana.

Commenting on management, Peter Marrone said, “Yamana and Viceroy have been involved in strategic discussions for some time and in that time, it has become very apparent that not only do Viceroy and Yamana share a common strategic outlook, but we espouse a common vision for our shareholders.”

Full details of the offer will be included in the formal offer and take-over circular to be filed with the regulatory authorities and mailed to Viceroy shareholders in accordance with applicable securities laws. The offer will remain open for 35 days following the mailing date and will be subject to certain conditions relating to receipt of requisite regulatory approvals, the absence of any material changes and acceptance of the offer by Viceroy shareholders owning not less than two-thirds of the Viceroy common shares on a fully-diluted basis. A resource estimate will be made available around the time of mailing of the circular.

If the support agreement is terminated in certain circumstances, Viceroy has agreed to pay Yamana a termination fee of 3.25% of Viceroy’s market capitalization on a fully diluted basis.

Yamana’s financial advisor is National Bank Financial Inc. and its legal advisors are Cassels Brock & Blackwell LLP and Dorsey & Whitney LLP. Canaccord Adams and Genuity Capital Markets acted as financial advisors to the Special Committee of the Board of Directors of Viceroy. Viceroy’s legal advisors are DuMoulin Black LLP and Blake, Cassels, & Graydon LLP.

All such policies of insurance shall remain in force and effect (subject to taking into account insurance market conditions and offerings and industry practices) and shall not be cancelled or otherwise terminated as a result of any of the Contemplated Transactions other than such cancellations as would not individually or in the aggregate have a Material Adverse Effect with respect to Yamana or such cancellations as have been disclosed to Viceroy.

(m)	Environmental. All operations of Yamana and its material subsidiaries have been and are now being conducted in compliance with all applicable Laws, including applicable Environmental Laws, except where the failure to be in compliance would not, individually or in the aggregate, have a Material Adverse Effect with respect to Yamana. Except as Disclosed Publicly, or except for those with respect to which adequate provision in accordance with GAAP has been made on the Yamana Financial Statements or a predecessor to Yamana, neither Yamana nor any of its material subsidiaries, is subject to:

	(i)	any proceeding, application, order or directive which relates to environmental, health or safety matters, and which may require any material work, repairs, construction or expenditures; or

	(ii)	any demand or notice with respect to any Environmental Laws applicable to Yamana or any material subsidiary including, without limitation, any regulations respecting the use, storage, treatment, transportation or disposition of any pollutant, contaminant, waste of any nature, hazardous substance, hazardous material, toxic substance, dangerous substance or dangerous good as defined, judicially interpreted or identified in any Environmental Law;

which, in each case, individually or in the aggregate would have a Material Adverse Effect with respect to Yamana.

(n)

Property and Title. Applying customary standards in the Canadian mining industry, each of Yamana and its material subsidiaries has sufficient title, clear of any title defect or Liens (other than as Disclosed Publicly), to its operating properties and properties with estimated proven and probable mineral reserves and/or estimated mineral resources (other than property to which it is lessee, in which case it has a valid leasehold interest) and has good and sufficient title to the real property interests including, without limitation, fee simple estate of and in real property, leases, easements, rights of way, permits or licences from landowners or authorities permitting the use of land by Yamana and its material subsidiaries necessary to permit the operation of their respective businesses as presently owned and conducted. Yamana and its material subsidiaries hold all mineral rights required to conduct their respective business and operations as currently conducted, except to the extent that a failure to do so would not constitute a Material Adverse Effect with respect to Yamana. All mineral rights held by Yamana and its material subsidiaries are free and clear of all Liens and royalty burdens (other than as Disclosed Publicly), and none of such mineral rights are subject to reduction by reference to mine payout or otherwise except for those created in the

- 27 -

ordinary course of business and which would not have a Material Adverse Effect with respect to Yamana.

The most recent estimated proven and probable mineral reserves and estimated indicated, measured and inferred mineral resources Disclosed Publicly by Yamana have been prepared and disclosed in all material respects in accordance with accepted engineering practices and all applicable Laws. There has been no material reduction in the aggregate amount of estimated mineral reserves, estimated mineral resources or mineralized material of Yamana and its material subsidiaries, taken as a whole, from the amounts most recently Disclosed Publicly by Yamana other than depletion as a result of mining activities.

(p)	Operational Matters. Except as would not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect with respect to Yamana:

	(ii)	all rentals, payments, and obligations due and payable or performable on or prior to the date hereof under or on account of any of the direct or indirect assets of Yamana and its material subsidiaries have been duly paid, performed, or provided for prior to the date hereof;

	(iii)	all mines where Yamana or a material subsidiary of Yamana is operator at the relevant time have been developed in accordance with standard mining practices and in compliance with all applicable Laws;

	(iv)	mines located in or on the lands of Yamana or any material subsidiary, or lands pooled or unitized therewith, which have been abandoned by Yamana or any material subsidiary of Yamana, have been abandoned in accordance with good mining practices and in compliance with all applicable Laws;

	(v)	all future abandonment, remediation and reclamation obligations have been accurately Disclosed Publicly by Yamana without omission of information necessary to make the disclosure not misleading; and

	(vi)	all costs, expenses, and liabilities payable on or prior to the date hereof under the terms of any contracts and agreements to which Yamana or any of its material subsidiaries is directly or indirectly bound have been properly and timely paid, except for such expenses that are being currently paid prior to delinquency in the ordinary course of business.

	(s)	Permits. Yamana has obtained and is in compliance with all permits required by applicable Laws, necessary to conduct its current businesses as they are now being conducted, other than where the absence of such Permits or the failure to comply would not, individually or in the aggregate, have a Material Adverse Effect on Yamana.

(4) If Viceroy receives a request for material non-public information from a person who proposes an unsolicited bona fide Acquisition Proposal and the Board of Directors of Viceroy determines that such proposal would be, if consummated in accordance with its terms, a Superior Proposal or reasonably determines that such Acquisition-Proposal could likely lead to a Superior Proposal, then, and only in such case, the Board of Directors of Viceroy may, subject to the execution by such person of a confidentiality agreement having substantially the same terms as the Confidentiality Agreement, provide such person with access to information regarding Viceroy; provided, however, that the person making the Acquisition Proposal shall not be precluded thereunder from making the Acquisition Proposal, and provided further that Viceroy sends a copy of any such confidentiality agreement to Yamana immediately upon its execution and Yamana is immediately provided with a list of all information provided to such person and is immediately provided with access to information similar to that which was provided to such person.

(5) Viceroy shall ensure that its officers and directors and those of its subsidiaries and any financial or other advisors or representatives retained by it are aware of the provisions of this Section, and it shall be responsible for any breach of this Section by any such person or its advisors or representatives.

(6) Nothing contained in this Section 7.1 shall prohibit the Board of Directors of Viceroy from withdrawing, modifying, qualifying or changing its recommendations to Viceroy Shareholders in respect of the Offer or from making any disclosure to Viceroy Shareholders prior to the Expiry Date if, in the good faith judgment of the Board of Directors, after consultation with outside counsel, such action is necessary for the Board of Directors to act in a manner consistent with its fiduciary duties or is otherwise required under applicable Laws, provided that, in the case of any proposal in respect of any such withdrawal, modification, qualification or change which does not relate to an Acquisition Proposal or a Superior Proposal and except as may be necessary for the Board of Directors to act in a manner consistent with its fiduciary duties, not less than 48 hours before the Board of Directors considers any proposal in respect of any such withdrawal, modification, qualification or change, Viceroy shall give Yamana written notice of such proposal and promptly advise Yamana of the proposed consideration of such proposal.

7.2 Right to Match

(1) Subject to Section 7.2(2), Viceroy covenants that it will not accept, approve, recommend or enter into any agreement, understanding or arrangement in respect of a Acquisition Proposal (other than a confidentiality agreement permitted by Section 7.1(4)) unless:

(a)

the Acquisition Proposal constitutes a Superior Proposal;

- 38 -

	(b)	Viceroy has complied with its obligations under Section 7.1 and the other provisions of this Article VII;

	(c)	Viceroy has provided Yamana with notice in writing that there is a Superior Proposal together with all documentation related to and detailing the Superior Proposal (including a copy of the confidentiality agreement between Viceroy and the person making the Superior Proposal if not previously delivered) at least four business days prior to the date on which the Board of Directors proposes to accept, approve, recommend or to enter into any agreement relating to such Superior Proposal;

	(d)	a period (the “Response Period”) of four business days shall have elapsed from the later of the date Yamana received notice of Viceroy’s proposed determination to accept, approve, recommend or to enter into any agreement relating to such Superior Proposal, and the date Yamana received a copy of the written proposal in respect of the Acquisition Proposal and, if Yamana has offered to amend the terms of the Offer in accordance with this Section, during such four business day period, the Board of Directors (after receiving advice from its financial advisors and outside legal counsel) shall have determined in good faith and by formal resolution that the Acquisition Proposal continues to be a Superior Proposal compared to the proposed amendment to the terms of the Offer by Yamana;

	(e)	Viceroy concurrently terminates this Agreement pursuant to Section 8.2(1)(f), and

	(f)	Viceroy has previously paid, or concurrently will pay, to Yamana the Termination Payment.

(2) During the Response Period, Yamana will have the right, but not the obligation, to offer to amend the terms of the Offer. The Board of Directors will review, in good faith in exercise of its fiduciary duties, any such proposal by Yamana to amend the terms of the Offer, including an increase in, or modification of, the consideration to be received by the holders of Common Shares, to determine whether the Acquisition Proposal to which Yamana is responding would be a Superior Proposal when assessed against the Offer as it is proposed by Yamana to be amended. If the Board of Directors does not so determine, the Board of Directors of Viceroy will promptly reaffirm its recommendation of the Offer as amended in the same manner as described in Section 2.4. Yamana and its legal counsel shall be given a reasonable opportunity to review and comment on the form and content of any such press release prior to its issue. If the Board of Directors does so determine, Viceroy may on termination of this Agreement in accordance with Section 8.2(1)(f) and payment of the fee to Yamana pursuant to Section 7.3, approve, recommend, accept or enter into an agreement, understanding or arrangement to proceed with the Superior Proposal.

(3) Each successive amendment to any Acquisition Proposal that results in an increase in, or modification of, the consideration (or value of such consideration) to be received by the holders of Common Shares shall constitute a new Acquisition Proposal for the purposes of this Section 7.2 and Yamana shall be afforded a new Response Period in respect of each such Acquisition Proposal.

7.3 Termination Payments

Notwithstanding and in addition to any other provision relating to the payment of fees, including the payment of brokerage fees, if after the execution of this Agreement the Offer is not consummated because:

(a)

Yamana shall have terminated this Agreement pursuant to Section 8.2(1)(d);

- 39 -

	(b)	Viceroy shall have terminated this Agreement pursuant to Section 8.2(1)(f); or

	(c)	Viceroy shall have materially breached its obligations under Section 7.1 or Section 7.2,

then Viceroy shall pay to Yamana, within two business days of the first to occur of (a), (b) or (c) above, the amount of Cdn. $20.1 million in immediately available funds to an account designated by Yamana.

7.4 Access to Information; Confidentiality

(1) From the date hereof until the earlier of the Effective Time and the termination of this Agreement, Viceroy shall, and shall cause its subsidiaries and officers, directors, employees, independent auditors, accounting advisers and agents to, afford Yamana and to its officers, employees, agents and representatives of the other Party such access as may reasonably be required at all reasonable times, including for the purpose of facilitating integration business planning, to Viceroy’s officers, employees, agents, properties, books, records and Contracts, and shall furnish Yamana with all data and information as may reasonably be requested. Yamana and Viceroy acknowledge and agree that information furnished pursuant to this Section shall be subject to the terms and conditions of the Confidentiality Agreement.

(2) Yamana and Viceroy acknowledge that information received pursuant to Section 7.4 may be personal information under applicable Laws, or non-public or proprietary in nature and therefore all such information shall be deemed to be “Confidential Information” for purposes of the Confidentiality Agreement. Yamana and Viceroy further acknowledge their obligation to maintain the confidentiality of such Confidential Information in accordance with the Confidentiality Agreement. If any material is withheld by Viceroy or Yamana or any of their subsidiaries (the “Disclosing Party”) because of the confidential nature of such material, or otherwise, the Disclosing Party or such subsidiary shall inform the other (the “Receiving Party”) as to the general nature of what is being withheld and such information may, in the sole discretion of the Disclosing Party, be disclosed to external advisors of the Receiving Party.

(3) Without limiting the generality of Sections 7.4(1) and (2) above, until the Mailing Date, each party shall make available to the other such information, documentation and access to personnel and advisors to allow the offer to conduct confirmatory due diligence with respect to corporate, financial, legal and title due diligence. The purpose of such due diligence shall be solely to permit each party to confirm the accuracy in all material respects of representations and warranties, the material compliance with all covenants and the absence of any undisclosed fact which would have a Material Adverse Effect on the other party.

7.5 Alternative Transaction

Viceroy agrees to cooperate in good faith with Yamana and to take all reasonable steps and actions to assist Yamana to complete the Offer as promptly as practicable. In addition, in the event that Yamana concludes that it is necessary or desirable to proceed with another form of transaction (such as a plan of arrangement or amalgamation) whereby Yamana or its affiliates would effectively acquire all of the Common Shares within the same time periods and on economic terms having consequences to the Viceroy Shareholder that are equivalent to or better than those contemplated by this Agreement (an “Alternative Transaction”), Viceroy agrees to support the completion of such Alternative Transaction in the same manner as the Offer and shall otherwise fulfill its covenants contained in this Agreement in respect of such Alternative Transaction.

- 44 -

9.7 Severability

If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party.
