Silver Wheaton Reports Record Annual Earnings and Operating Cash Flows

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 25, 2008) - Silver Wheaton Corp. (TSX:SLW)(NYSE:SLW) is pleased to announce record annual 2007 net earnings of US$92 million (US$0.41 per share) and record operating cash flows of US$119 million (US$0.54 per share). Fourth quarter net earnings and operating cash flows were US$25 million (US$0.11 per share) and US$34 million (US$0.15 per share), respectively.

2007 HIGHLIGHTS (12 Months)

- Record net earnings of US$91.9 million (US$0.41 per share) from the sale of 13.1 million ounces of silver, compared to US$85.2 million (US$0.40 per share) from the sale of 13.5 million ounces of silver in 2006.

- Record operating cash flows of US$119.3 million (US$0.54 per share), compared to US$104.7 million (US$0.50 per share) in 2006.

- With 2007 investments in silver purchase contracts (Penasquito and Stratoni) totalling US$558 million, annual silver sales are expected to almost double to 25 million ounces by 2010 without any further capital expenditures. This growth was financed by way of operating cash flows and a US$500 million debt facility.

- Subsequent to year end, Goldcorp sold its entire 48% interest in Silver Wheaton, on a bought deal basis, for aggregate gross cash proceeds of Cdn$1.6 billion.

FOURTH QUARTER HIGHLIGHTS (3 Months)

- Net earnings of US$24.9 million (US$0.11 per share) from the sale of 3.5 million ounces of silver, compared to US$23.8 million (US$0.11 per share) from the sale of 3.5 million ounces of silver in 2006.

- Record operating cash flows of US$34.4 million (US$0.15 per share), compared to US$29.8 million (US$0.14 per share) in 2006.

- On December 20, 2007, the Company signed a binding letter agreement to purchase between 45% and 90% of silver produced by Augusta Resource Corporation's Rosemont Copper Project in Arizona for the life of mine. Subject to the finalization of the transaction structure, including tax considerations, and upon receipt of all necessary mining permits by Augusta, Silver Wheaton will pay an upfront cash payment ranging in value from US$135 million to US$165 million to acquire 45% of the payable silver, and US$240 million to US$320 million to acquire 90% of the payable silver, produced for the life of mine.

"2007 was our best year ever, with record earnings, record cash flows, and two very accretive acquisitions," said Peter Barnes, President and Chief Executive Officer of Silver Wheaton. "These acquisitions set us on a path to almost double our silver ounces sold by 2010, to 25 million ounces a year, and boosting our long term cash flow per share by 40% per annum. 2008 promises to be even better than 2007, with a strong silver price, the Goldcorp share overhang recently removed, and a robust potential deal flow."

OVERVIEW

Silver Wheaton Corp. ("Silver Wheaton" or the "Company") is the largest public mining company with 100% of its revenue from silver production. The Company's goal is to be recognized as the most profitable and best managed silver company in the world.

The Company has entered into five long-term silver contracts with Goldcorp (Luismin mines in Mexico and Penasquito project in Mexico), Lundin Mining (Zinkgruvan mine in Sweden), Glencore (Yauliyacu mine in Peru) and Hellas Gold (Stratoni mine in Greece), whereby Silver Wheaton acquires silver production from the counterparties at a price of $3.90 per ounce, subject to an inflationary adjustment. In addition, on December 20, 2007, the Company signed a binding letter agreement to acquire between 45% and 90% of the life of mine silver to be produced by Augusta Resource Corporation's ("Augusta") Rosemont Copper Project ("Rosemont") in Arizona. As a result, the primary drivers behind the Company's financial results are the volume of silver production at the various mines and the price of silver.

The Company expects, based upon its current contracts, to have annual silver sales of approximately 15 million ounces in 2008, increasing to 19 million ounces in 2009 and 25 million ounces in 2010. Silver Wheaton is actively pursuing further growth opportunities.

Changes in sales, net earnings and cash flow from operations from quarter to quarter are affected primarily by fluctuations in production at the mines and timing of shipments that are in the normal course of operations, as well as changes in the price of silver. During the fourth quarter of 2007, the number of ounces sold was 13% higher than during the third quarter, due to increased production at Yauliyacu and Zinkgruvan, as well as delayed shipments at Zinkgruvan and Stratoni at the end of the third quarter for which the sales were recognized in the fourth quarter.

RESULTS OF OPERATIONS AND OPERATIONAL REVIEW

The Company has five business segments, the silver produced by the Luismin, Zinkgruvan, Yauliyacu and Stratoni mines, and corporate operations. The acquisition of silver from the Yauliyacu and Stratoni mines began in May 2006 and June 2007, respectively.

LUISMIN

On October 15, 2004, a 100% owned subsidiary of the Company, Silver Wheaton (Caymans) Ltd. ("SW Caymans"), entered into an agreement (amended on March 30, 2006) with Goldcorp to acquire all of the silver produced by Goldcorp's Luismin mining operations in Mexico (owned at the date of the transaction) for a period of 25 years. During 2007, SW Caymans purchased 6.9 million ounces (2006 - 9.0 million ounces) of silver at a total cash cost of $3.91 per ounce (2006 - $3.90 per ounce), and sold it for an average price of $13.35 per ounce (2006 - $11.57 per ounce). The number of ounces sold during the year decreased from 2006 due to a reduction in the average grade of ore milled at Luismin's San Dimas mine, from 436 grams per tonne in 2006 to 338 grams per tonne in 2007. The Company's cash flows and net earnings under the Luismin silver purchase contract for the year ended December 31, 2007 were $65.8 million (2006 - $68.3 million) and $62.5 million (2006 - $65.7 million) respectively.

As at December 31, 2007, the Luismin mines had proven and probable reserves, of 66.1 million ounces of silver, measured and indicated resources of 1.9 million ounces of silver and inferred resources of 183.2 million ounces of silver (as described in the Reserves and Resources section of this Management's Discussion and Analysis).

The results of the Luismin mine operations for the years ended December 31, 2007 and 2006 are shown below:

1) Grades exclude Nukay, a Luismin mine, which does not produce silver


During January 2007, Luismin sold the San Martin mine. Therefore, the results of the Luismin mine operations including the ore milled, grade, recovery and production figures, do not include the results of the San Martin mine after January 2007. In accordance with the Luismin silver contract, Luismin purchases all of the silver produced by the San Martin mine and continues to sell it to Silver Wheaton at $3.95 per ounce, subject to an inflationary adjustment on October 15 of each year. During the fourth quarter, silver sales at Luismin were approximately 148,000 ounces less than the silver production, due primarily to timing of product shipments.

ZINKGRUVAN

On December 8, 2004, SW Caymans entered into an agreement to acquire all of the silver produced by Lundin Mining's Zinkgruvan mining operations in Sweden ("Zinkgruvan") for the life of mine. During 2007, SW Caymans purchased 1.8 million ounces (2006 - 1.6 million ounces) of silver under the contract at a total cash cost of $3.90 per ounce, and sold 1.8 million ounces (2006 - 1.7 million ounces) for an average price of $13.72 per ounce (2006 - $11.21 per ounce). The Company's cash flows and net earnings under the Zinkgruvan silver purchase contract for 2007 were $18.0 million (2006 - $13.2 million) and $15.1 million (2006 - $9.5 million) respectively.

As at December 31, 2006, Zinkgruvan had proven and probable silver reserves of 27.9 million ounces, measured and indicated silver resources of 6.7 million ounces and inferred silver resources of 26.1 million ounces (as described in the Reserves and Resources section of this Management's Discussion and Analysis).

YAULIYACU

On March 23, 2006, SW Caymans entered into an agreement with Glencore International AG ("Glencore") to acquire up to 4.75 million ounces of silver per year for a period of 20 years, based on the production from Glencore's Yauliyacu mining operations in Peru. During 2007, SW Caymans purchased 3.4 million ounces (2006 - 2.9 million ounces) of silver at a total cash cost of $3.90 per ounce, and sold it for an average price of $13.38 per ounce (2006 - $12.48 per ounce). The Company's cash flows and net earnings under the Yauliyacu silver purchase contract for 2007 were $32.6 million (2006 - $24.6 million) and $20.1 million (2006 - $14.0 million) respectively.

During the term of the contract, Silver Wheaton has a right of first refusal on any future sales of silver streams from the Yauliyacu mine and a right of first offer on future sales of silver streams from any other mine owned by Glencore at the time of the initial transaction. In addition, Silver Wheaton has an option to extend the 20 year term of the contract in five year increments, on substantially the same terms as the existing contract, subject to an adjustment related to silver price expectations at the time and other factors.

As at December 31, 2006, Yauliyacu had proven and probable silver reserves of 13.1 million ounces, measured and indicated silver resources of 36.5 million ounces and inferred silver resources of 69.2 million ounces (as described in the Reserves and Resources section of this Management's Discussion and Analysis).

STRATONI

On April 23, 2007, SW Caymans entered into an agreement with Hellas Gold S.A. ("Hellas Gold"), a subsidiary of European Goldfields Ltd., to acquire all of the silver produced from Hellas Gold's Stratoni mining operations in Greece for the life of mine. Silver Wheaton made an upfront cash payment of $57.5 million. In addition, a per ounce cash payment of the lesser of $3.90 and the prevailing market price is due (subject to an inflationary adjustment commencing in 2010), for silver delivered under the contract.

During June 2007, the Company began purchasing silver under the contract and during the year, SW Caymans purchased 0.9 million ounces of silver at a total cash cost of $3.90 per ounce, and sold it for an average price of $13.57 per ounce. The Company's cash flows and net earnings under the Stratoni silver purchase contract for 2007 were $8.3 million and $4.9 million respectively.

During the term of the contract, Silver Wheaton has a right of first refusal on any future sales of silver streams from any other mine owned by European Goldfields or Hellas Gold.

On December 20, 2007, the Company entered into a binding letter agreement to acquire between 45% and 90% of the silver produced by Augusta's Rosemont Copper Project in Arizona for the life of mine. Augusta must elect the percentage of life of mine silver subject to the transaction, which will be between a minimum of 45% and a maximum of 90%, on or before March 31, 2008.

Subject to the finalization of the transaction structure, including tax considerations, Silver Wheaton will pay an upfront cash payment ranging in value from $135 million to $165 million to acquire 45% of the payable silver, and $240 million to $320 million to acquire 90% of the payable silver, produced for the life of mine.

The upfront payment will be made on a drawdown basis to fund construction of the mine as construction milestones are achieved. Silver Wheaton will not be required to pay any further ongoing per ounce payments for silver delivered from Rosemont and is not required to fund or contribute to ongoing capital expenditures, including expansion scenarios. Augusta will provide a completion guarantee that the Rosemont mine will be constructed with certain minimum production criteria by certain dates.

The transaction is subject to (a) Augusta receiving all necessary permits to construct and operate a mine in accordance with their August 2007 Rosemont Feasibility Study (the "Feasibility Study"), (b) Augusta having entered into committed arrangements for sufficient financing to construct and operate the mine, and (c) execution by the parties of definitive agreements on or before June 30, 2008 as well as receipt of any required regulatory approvals and third-party consents. Augusta expects production at the Rosemont project to start in late 2010 with an average of 2.7 million ounces of silver produced each year over the life of mine, currently expected to be a minimum of 18 years.

included in General and administrative $ 2,735 $ 1,768 $ 463


General and administrative expenses totaled $9.7 million during 2007 compared with $5.7 million during 2006. This increase resulted primarily from increased insurance costs, exchange listing and investor relations costs, and salary and stock based compensation expenses incurred as a result of hiring additional employees. Stock based compensation expense during 2007, a non cash item, included $2.6 million (2006 - $1.7 million) of amortization of the fair value of share purchase options issued, which was determined using the Black-Scholes option valuation method. During the year, 21,333 (2006 - 15,000) restricted share rights and 945,000 (2006 - 550,000) share purchase options were issued.

The Company incurred interest costs of $13.3 million and upfront debt financing costs of $2.5 million during the year in order to finance the acquisition of the Penasquito silver contract and as a result these amounts were capitalized to the cost of the contract. In 2006, the Company incurred interest expense of $0.7 million and upfront debt financing costs of $1.1 million.

Project evaluation expenses of $0.4 million (2006 - $0.2 million) were incurred in pursuing additional silver acquisition opportunities.

Interest income during the year of $1.5 million (2006 - $3.2 million) was the result of interest earned on cash balances held in short-term money market instruments.

Effective January 1, 2007, the Company has adopted the provisions of Section 3855, Financial Instruments - Recognition and Measurement, which classifies the warrants held by the Company for long term investment purposes as derivatives that are marked-to-market each reporting period with any gain or loss reflected in net earnings. The loss recorded in 2007 from the mark-to-market of the warrants held was $1.7 million.

NON-GAAP MEASURES - TOTAL CASH COSTS PER OUNCE OF SILVER CALCULATION

Silver Wheaton has included, throughout this document, certain non-GAAP performance measures, including total cash costs of silver on a sales basis. These non-GAAP measures do not have any standardized meaning prescribed by GAAP, nor are they necessarily comparable with similar measures presented by other companies. Cash costs are presented as they represent an industry standard method of comparing certain costs on a per unit basis. The Company believes that certain investors use this information to evaluate the Company's performance. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. During the year ended December 31, 2007, the Company's total cash costs, which were equivalent to the Company's Cost of Sales in accordance with GAAP, were $3.91 per ounce of silver (2006 - $3.90 per ounce).

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 2007, the Company had cash and cash equivalents of $10.0 million (December 31, 2006 - $60.0 million) and a working capital deficiency of $23.2 million (December 31, 2006 - working capital of $40.0 million). Included in the working capital deficiency at December 31, 2007 is the current portion of long term bank debt of $28.6 million (December 31, 2006 - $nil). During the year, the Company generated operating cash flows of $119.3 million compared with $104.7 million during 2006. The Company applies surplus cash flows to pay down the revolving bank debt facility, which is recorded as a long term liability.

In the opinion of management, cash flows are sufficient to support the Company's normal operating requirements on an ongoing basis.

LONG TERM INVESTMENTS

During the year, Silver Wheaton invested $17.0 million to acquire significant ownership positions in publicly traded companies owning substantial undeveloped silver resources. At December 31, 2007, the Company held investments in such companies with a market value of $119.4 million.

Bear Creek

At December 31, 2007, Silver Wheaton owned 8,146,505 common shares and warrants exercisable to acquire an additional 100,000 common shares, representing approximately 18% of the outstanding shares of Bear Creek on an undiluted basis. At December 31, 2007, the fair value of the Company's investment in Bear Creek was $59.4 million.

Revett

At December 31, 2007, Silver Wheaton owned 12,382,900 common shares and warrants exercisable to acquire an additional 2,400,000 common shares, representing approximately 17% of the outstanding shares of Revett Minerals Inc. ("Revett") on an undiluted basis. At December 31, 2007, the fair value of the Company's investment in Revett was $10.8 million.

Sabina

At December 31, 2007, Silver Wheaton owned 7,800,000 common shares and warrants exercisable to acquire an additional 3,900,000 common shares, representing approximately 12% of the outstanding shares of Sabina Silver Corporation ("Sabina") on an undiluted basis. At December 31, 2007, the fair value of the Company's investment in Sabina was $17.0 million.

Mines Management

During 2007, Silver Wheaton acquired by way of private placement 2,500,000 common shares of Mines Management, Inc. ("Mines Management") at a price of $4.00 per share, for total consideration of $10.0 million. As a result, at December 31, 2007, Silver Wheaton owned 2,500,000 common shares, representing approximately 11% of the outstanding shares of Mines Management on an undiluted basis. At December 31, 2007, the fair value of the Company's investment in Mines Management was $8.6 million.

ACQUISITION OF SILVER INTERESTS

On April 23, 2007, the Company entered into an agreement with Hellas Gold, a subsidiary of European Goldfields Ltd., to acquire all of the silver produced from Hellas Gold's Stratoni mining operations in Greece for the life of mine. Silver Wheaton made an upfront cash payment of $57.5 million. In addition, a per ounce cash payment of the lesser of $3.90 and the prevailing market price is due (subject to an inflationary adjustment commencing in 2010), for silver delivered under the contract.

On July 24, 2007, the Company entered into an agreement with Goldcorp to acquire 25% of the silver produced from the Penasquito project in Mexico for the life of mine. Silver Wheaton made an upfront cash payment of $485 million. In addition, a per ounce cash payment of the lesser of $3.90 and the prevailing market price is due (subject to an inflationary adjustment commencing in 2011), for silver delivered under the contract.

On December 20, 2007 the Company signed a binding letter agreement to acquire between 45% and 90% of the life of mine silver to be produced by Augusta's Rosemont Copper Project in Arizona. Augusta must elect the percentage of life of mine silver subject to the transaction, which will be between a minimum of 45% and a maximum of 90%, on or before March 31, 2008. Subject to the finalization of the transaction structure, including tax considerations and upon receipt of all necessary mining permits by Augusta, Silver Wheaton will pay an upfront cash payment ranging in value from $135 million to $165 million to acquire 45% of the payable silver, and $240 million to $320 million to acquire 90% of the payable silver, produced for the life of mine.

BANK DEBT

On July 24, 2007, the Company cancelled its undrawn $25 million revolving loan facility and entered into a credit agreement with the Bank of Nova Scotia and BMO Capital Markets, as co-lead arrangers and administrative agents, to borrow $200 million under a non revolving term loan (the "Term Loan") and up to $300 million under a revolving term loan (the "Revolving Loan"). The Revolving Loan is for a period of 7 years and the Term Loan is to be repaid in equal installments over a period of 7 years, however, prepayments are allowed at any time. Silver Wheaton has committed to pay down the Revolving Loan, within 61 days after the end of each fiscal quarter, by an amount equal to 90% of the cash flows reported for the quarter. The Revolving Loan can be drawn down at any time to finance acquisitions or investments. In order to fund the Penasquito transaction, the Term Loan was drawn in full and the Revolving Loan was drawn in the amount of $246 million.

Amounts drawn incur interest at LIBOR plus 0.875% to 1.75% per annum dependent upon the Company's leverage ratio. Undrawn amounts are subject to a 0.2% to 0.45% per annum commitment fee dependent on the Company's leverage ratio. Under the credit agreement, the Company is required to maintain a debt service coverage ratio greater than or equal to 1.25 : 1, a Leverage Ratio less than or equal to 5 : 1 (decreasing to 4 : 1 on September 30, 2008 and to 3.5 : 1 on September 30, 2009), and a Tangible Net Worth greater than 80% of the Tangible Net Worth at June 30, 2007 plus 50% of Net Income for each fiscal quarter thereafter. Both the Term Loan and the Revolving Loan are secured against the Company's assets, including the Company's silver interests. The Company has paid $2.5 million in debt financing costs relating to the credit agreement which were capitalized to the cost of the Penasquito contract. During 2007, the Company repaid $7.1 million and $19.0 million of the balances outstanding on the Term Loan and Revolving Loan, respectively.

PROMISSORY NOTE

On March 30, 2006, as partial consideration for amendments made to the Luismin silver purchase contract, the Company issued a non-interest bearing $20 million promissory note to Goldcorp, due on March 30, 2007. The promissory note was repaid in full during March 2007.

CONTRACTUAL OBLIGATIONS

Silver Interests

In connection with the Luismin, Zinkgruvan and Stratoni silver contracts, the Company has committed to purchase 100% of the silver produced by each mine for a per-ounce cash payment of the lesser of $3.95, $3.96 and $3.90 respectively, and the then prevailing market price, subject to an annual inflationary adjustment. This inflationary adjustment is subject to a minimum of 0.4% and a maximum of 1.65% per annum for Luismin and Zinkgruvan, and is fixed at 1% per annum for Stratoni. In connection with the Yauliyacu silver purchase contract, the Company has committed to purchase up to 4.75 million ounces of silver per year, based on production at the Yauliyacu mine, for a per-ounce cash payment of $3.90, subject to an inflationary adjustment.

SHARE CAPITAL

During the year, the Company received cash proceeds of $7.3 million (2006 - $7.0 million) from the exercise of 2,331,965 (2006 - 2,477,334) share purchase options at a weighted average exercise price of Cdn$3.39 (2006 - Cdn$3.27) per option. As of February 21, 2008, there were 223,348,617 outstanding common shares, 3,105,701 share purchase options and 163,212,289 share purchase warrants, which are convertible into 38,867,178 common shares.

RISKS AND UNCERTAINTIES

The primary risk factors affecting the Company and its profitability include fluctuations in silver production, currency fluctuations, government regulations, foreign operations, income taxes and changes in silver prices.

SILVER PRODUCTION

The Company has agreed to purchase all of the silver produced by the Luismin, Zinkgruvan and Stratoni mines, up to 4.75 million ounces per year based on the production from the Yauliyacu mine and 25% of the production from the Penasquito mine. Other than the security interests which have been granted to Silver Wheaton, the Company has no contractual rights relating to the mine operations, nor does it have any legal ownership in or operational control of the mines. Other than the penalties that may be payable by Luismin, Zinkgruvan, and Yauliyacu to Silver Wheaton, the Company will not be entitled to any compensation if the mines do not meet their forecasted silver production targets in any specified period or if they shut down or discontinue their mining operations on a temporary or permanent basis.

CURRENCY FLUCTUATIONS

Exchange rate fluctuations may affect the costs that the Company incurs in its operations. Silver is sold in US dollars and a portion of the Company's costs are incurred in Canadian dollars. From time to time, the Company may transact currency hedging to reduce the risk associated with currency fluctuations. There is no assurance that its hedging strategies will be successful. Currency hedging may require margin activities. Sudden fluctuations in currencies could result in margin calls that could have an adverse effect on the Company's financial position.

GOVERNMENT REGULATIONS

The mining, processing, development and mineral exploration activities of the companies that Silver Wheaton purchases silver from are subject to various laws governing prospecting, development, production, taxes, labour standards and occupational health, mine safety, toxic substances, land use, water use, land claims of local people and other matters. No assurance can be given that new rules and regulations will not be enacted or that existing rules and regulations will not be applied in a manner which could result in production disturbances.

FOREIGN OPERATIONS

SW Caymans purchases silver from companies that operate in Mexico, Sweden, Peru and Greece, and as such the Company's operations are exposed to various levels of political, economic and other risks and uncertainties. These risks and uncertainties vary between the four countries and include, but are not limited to, terrorism; hostage taking; military repression; extreme fluctuations in currency exchange rates; high rates of inflation; labour unrest; the risk of war or civil unrest; expropriation and nationalization; renegotiation or nullification of existing concessions, licenses, permits and contracts; illegal mining; changes in taxation policies; restrictions on foreign exchange and repatriation; and changing political conditions, currency controls and governmental regulations that favour or require the awarding of contracts to local contractors or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction.

Failure of these companies to comply strictly with applicable laws, regulations and local practices relating to mineral right applications and tenure, could result in loss, reduction or expropriation of entitlements.

The occurrence of these various factors and uncertainties cannot be accurately predicted and could have an adverse effect on the Company's operations or profitability.

INCOME TAXES

As the Company's profit is derived from its subsidiary, SW Caymans, which is incorporated and operated in the Cayman Islands, the Company's profits bear no income tax. Management views the subsidiary's profits as part of its permanent investment in the subsidiary, and it has determined that those profits will be reinvested in foreign jurisdictions for the foreseeable future, therefore, no current income taxes have been recorded.

Changes to taxation laws in either Canada or the Cayman Islands, could result in some or all of the Company's profits being subject to income tax. No assurance can be given that new taxation rules will not be enacted or that existing rules will not be applied in a manner which could result in the Company's profits being subject to income tax.

SILVER PRICES

Profitability of the Company depends on silver prices. A $1.00 per ounce change in the price of silver would impact 2008 net earnings by approximately $15 million.

Silver prices are affected by numerous factors such as the sale or purchase of silver by various central banks and financial institutions, interest rates, exchange rates, inflation or deflation, fluctuations in the value of the US dollar and foreign currencies, global and regional supply and demand, and the political and economic conditions of major silver producing countries throughout the world.

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenditures during the reporting period. Note 2 of the Company's audited consolidated financial statements describes all of the significant accounting policies.

SILVER INTERESTS

Silver interests are a significant asset of the Company, with a carrying value of $1.1 billion at December 31, 2007. This amount represents the capitalized expenditures related to the acquisition of the Luismin, Zinkgruvan, Yauliyacu, Stratoni and Penasquito silver purchase contracts. Each of these mines estimates the reserves and resources relating to each contract. Silver Wheaton uses these estimates to determine the estimated number of ounces that will be acquired from each operation and the cost of these assets is separately allocated to reserves, resources and exploration potential. The value allocated to reserves is classified as depletable and is depreciated on a unit-of-sale basis over the estimated recoverable proven and probable reserves at the mine corresponding to the specific contract. The value associated with resources and exploration potential is the value beyond proven and probable reserves at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category as a result of the conversion of resources or exploration potential into reserves. Evaluations of the carrying values of each contract are undertaken annually to determine if estimated undiscounted future net cash flows are less than the carrying value. Estimated undiscounted future net cash flows are calculated using estimated production, sales prices and purchase costs. If it is determined that the future net cash flows from an operation are less than the carrying value then a write-down is recorded with a charge to operations. At December 31, 2007, no write-down was required.

REVENUE RECOGNITION

Revenue from the sale of silver is recognized in the accounts when persuasive evidence of an arrangement exists, title and risk passes to the buyer, collection is reasonably assured and the price is reasonably determinable. Revenue from the sale of silver may be subject to adjustment upon final settlement of estimated metal prices, weights, and assays. Adjustments to revenue for metal prices are recorded monthly and other adjustments are recorded on final settlement.

CHANGES IN ACCOUNTING POLICIES

The Company adopted the provisions of Sections 3855, Financial Instruments - Recognition and Measurement, 3861 - Financial Instruments - Disclosure and Presentation, 1530 - Comprehensive Income, 3865 - Hedges and 3251 - Equity, on January 1, 2007 which address the classification, recognition and measurement of financial instruments in the financial statements and the inclusion of other comprehensive income. As a result of adopting these new standards the Company recorded a non-cash increase of $39.5 million to opening long-term investments, a non-cash increase of $3.3 million to future income tax liability and a non-cash pre-tax adjustment of $37.7 million ($31.1 million net of tax) as a one-time cumulative effect of a change in accounting policy in opening accumulated other comprehensive income. In addition, the Company recorded a non-cash increase of $4.9 million to opening retained earnings to recognize the value of income tax losses not previously recognized, and to record the cumulative effect of the change in accounting policy as it relates to warrants held by the Company and a decrease in deferred debt financing costs.

The Company has added two new accounting policies in relation to these new standards, as described below.

LONG TERM INVESTMENTS

Long-term investments in equity securities are classified as available-for-sale because the Company intends to hold the investments for more than one year. Unrealized holding gains and losses related to available-for-sale investments are excluded from net income and are included in other comprehensive income until such gains or losses are realized or an other than temporary impairment is determined to have occurred.

Warrants held by the Company are for long-term investment purposes, however, due to their nature they meet the definition of a derivative and are marked-to-market on a quarterly basis. Mark-to-market gains and losses relating to the warrants are included in net income in the period they occur.

The Company estimates the fair value of financial instruments at the balance sheet date using quoted market prices for available-for-sale securities and a Black-Scholes option pricing model for warrants held.

INTEREST AND DEBT FINANCING COSTS

Interest and debt financing costs are expensed when they are incurred, unless they are directly attributable to the acquisition or construction of qualifying assets, which are assets that necessarily take a substantial period of preparation for their intended use or sale, in which case they are added to the cost of those assets until such time as the assets are substantially ready for their intended use or sale.

FUTURE CHANGES IN ACCOUNTING POLICIES

CAPITAL DISCLOSURES

The CICA issued a new accounting standard, Section 1535, Capital Disclosures ("Section 1535"), which requires the disclosure of both qualitative and quantitative information that enables users of financial statements to evaluate the entity's objectives, policies and processes for managing capital. Section 1535 specifies the disclosure of (i) an entity's objectives, policies and processes for managing capital; (ii) quantitative data about what the entity regards as capital; (iii) whether the entity has complied with any capital requirements; and (iv) if it has not complied, the consequences of such non-compliance. This new standard became effective for the Company January 1, 2008.

FINANCIAL INSTRUMENTS

The CICA issued two new accounting standards, Section 3862, Financial Instruments - Disclosures ("Section 3862"), and Section 3863, Financial Instruments - Presentation ("Section 3863"), which replace Handbook Section 3861, Financial Instruments - Disclosure and Presentation, revising and enhancing its disclosure requirements and carrying forward unchanged its presentation requirements for financial instruments. Sections 3862 and 3863 place increased emphasis on disclosures about the nature and extent of risks arising from financial instruments and how the entity manages those risks. These new standards will become effective for the Company for periods beginning on or after October 1, 2007.

IMPACT OF ADOPTING SECTIONS 1535, 3862 AND 3863

The Company is currently analyzing the requirements of these new standards.

RELATED PARTY TRANSACTIONS

At December 31, 2007, Goldcorp owned 48% of the Company's outstanding common shares. During the year, the Company purchased 6.9 million ounces (2006 - 9.0 million ounces) of silver from a subsidiary of Goldcorp at an average price of $3.91 per ounce (2006 - $3.90 per ounce), for total consideration of approximately $27.0 million (2006 - $35.0 million).

During the year, Silver Wheaton repaid a $20 million promissory note due to Goldcorp.

On July 24, 2007, SW Caymans entered into an agreement to acquire 25% of the life of mine silver production from Goldcorp's Penasquito project in Mexico, for an upfront cash payment of $485 million, as described elsewhere in this Management's Discussion and Analysis.

The Company has an agreement with Goldcorp whereby Goldcorp provides certain management and administrative services at cost. During the year, total costs reimbursed to Goldcorp were $193,000 compared to $249,000 during 2006. This agreement allows for cancellation by Silver Wheaton with 30 days notice at any time.

During May 2007, the Company entered into a 9 year lease agreement with Goldcorp for office space. The Company began making lease payments in December 2007 which totaled $17,500.

At December 31, 2007, the Company owed Goldcorp $152,000 (2006, Goldcorp owed the Company - $18,000).

On February 14, 2008, Goldcorp sold its entire 48% interest in Silver Wheaton by way of a secondary offering, as described in the subsequent event section of this Management's Discussion and Analysis.

SUBSEQUENT EVENT

Subsequent to year end, Goldcorp sold its entire 48% interest in Silver Wheaton of 108 million common shares, on a bought deal basis, at a price of Cdn$14.50 per common share for aggregate gross cash proceeds to Goldcorp of Cdn$1.6 billion.

CONTROLS AND PROCEDURES

DISCLOSURE CONTROLS AND PROCEDURES

Silver Wheaton's management, with the participation of the Chief Executive Officer and Chief Financial Officer, has evaluated the design and effectiveness of Silver Wheaton's disclosure controls and procedures, as defined in the rules of the U.S. Securities and Exchange Commission and Canadian Securities Administrators, as of December 31, 2007. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that Silver Wheaton's disclosure controls and procedures were effective as of December 31, 2007.

INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company's management, with the participation of its Chief Executive Officer and Chief Financial Officer, are responsible for establishing and maintaining adequate internal controls over financial reporting. Under the supervision of the Chief Financial Officer, the Company's internal controls over financial reporting are designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles ("GAAP"). The Company's controls include policies and procedures that:

- pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

- provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of the Company's management and directors; and

- provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the annual financial statements or interim financial statements.

The Company's management, including the Chief Executive Officer and Chief Financial Officer, believe that any disclosure controls and procedures or internal controls over financial reporting, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, they cannot provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by unauthorized override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Accordingly, because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

There have been no significant changes in the Company's internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.


FINANCIAL INSTRUMENTS

During the year ended December 31, 2007, the Company has used a mixture of cash, short-term debt and long-term debt to maintain an appropriate capital structure, ensuring sufficient liquidity required to meet the needs of the business and the flexibility to continue growing through acquisition. The Company does not use interest rate contracts or other derivative financial instruments to manage the risks associated with its operations and therefore, in the normal course of business, it is inherently exposed to currency, interest rate and commodity price fluctuations.

The Company holds certain financial instruments as long-term investments and therefore is inherently exposed to various risk factors including currency risk, market price risk and liquidity risk.

OUTLOOK

The Company expects, based upon its current contracts, to have silver sales of approximately 15 million ounces for the year ending December 31, 2008, increasing to 19 million ounces in 2009 and 25 million ounces in 2010.

The Company is unhedged and actively pursuing further growth opportunities.

Notes:
1. All Mineral Reserves and Mineral Resources have been calculated in
accordance with the standards of the Canadian Institute of Mining,
Metallurgy and Petroleum and National Instrument 43-101, or the AusIMM
JORC equivalent.
2. All Mineral Resources are exclusive of Mineral Reserves.
3. Mineral Resources which are not Mineral Reserves do not have
demonstrated economic viability.
4. Reserves and Resources are reported as of December 31, 2007, with the
following conditions or exceptions;
a. Reserves and Resources for Penasquito are reported as of August 9,
2007.
b. Reserves and Resources for San Martin are reported as of December
31, 2006 with the exception of the San Pedrito project, which is
reported as of December 31, 2005.
c. Reserves and Resources for Zinkgruvan are reported as of December
31, 2006.
d. Reserves and Resources for Yaliyacu are reported as of December 31,
2006.
e. Reserves and Resources for Stratoni are reported as of December 31,
2006.
5. Qualified Persons for the Mineral Reserve and Mineral Resource
estimates as defined by the National Instrument 43-101 are as follows:
a. San Dimas - Reynaldo Rivera, MAusIMM (Chief Geologist), Luismin
S.A. de C.V., the Mexican operating subsidiary of Goldcorp Inc.
b. Los Filos - Reynaldo Rivera, MAusIMM (Chief Geologist), Luismin
S.A. de C.V., the Mexican operating subsidiary of Goldcorp Inc.
c. Penasquito - Bob Bryson, P. Eng. (Vice President, Engineering),
Goldcorp Inc.
d. Stratoni - Patrick Forward (General Manager, Exploration), European
Goldfields.
e. San Martin - Reynaldo Rivera, MAusIMM (Chief Geologist), Luismin

6. Mineral Reserves are estimated using appropriate recovery rates and US$
commodity prices of $10 per ounce of silver unless otherwise noted
below;
a. $7.00 / oz silver - San Martin
b. $5.75 / oz silver - Zinkgruvan
7. Mineral Resources are estimated using appropriate recovery rates and
US$ commodity prices of $13 per ounce of silver, unless otherwise
noted below;
a. $8.00 / oz silver - San Martin
b. $5.50 / oz silver - The San Pedrito project at San Martin
c. $5.75 / oz silver - Zinkgruvan
8. Silver Wheaton's purchase agreement with Glencore provides for the
delivery of up to 4.75 million ounces of silver per year for 20 years
so long as production allows. Silver production at Yauliyacu in excess
of 4.75 million ounces per year is to the credit of Glencore; however,
in the event that silver produced at Yauliyacu in any year totals less
than 4.75 million ounces, the amount sold to Silver Wheaton in
subsequent years will be increased to make up for the shortfall, so
long as production allows. A portion of the reserves and resources from
Yauliyacu may relate to production which may be for the credit of
Glencore.
9. Penasquito reserves and resources represent the 25% attributable to
Silver Wheaton.
10. Silver is produced as a byproduct metal at the various operations,
therefore the economic cut-off applied to the reporting of silver
reserves and resources will be influenced by changes in the commodity
prices of other metals at the mine.
11. The Los Filos Project is not considered to be a material property to
the Company.


CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The information contained herein contains "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 and applicable Canadian securities legislation. Forward-looking statements include, but are not limited to, statements with respect to the future price of silver, the estimation of mineral reserves and resources, the realization of mineral reserve estimates, the timing and amount of estimated future production, costs of production, reserve determination and reserve conversion rates. Generally, these forward-looking statements can be identified by the use of forward-looking terminology such as "plans", "expects" or "does not expect", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved". Forward-looking statements are subject to known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, performance or achievements of Silver Wheaton to be materially different from those expressed or implied by such forward-looking statements, including but not limited to: risks related to the integration of acquisitions, the absence of control over mining operations from which Silver Wheaton purchases silver and risks related to these mining operations, including risks related to international operations, actual results of current exploration activities, actual results of current reclamation activities, conclusions of economic evaluations, changes in project parameters as plans continue to be refined, as well as those factors discussed in the section entitled "Description of the Business - Risk Factors" in Silver Wheaton's annual information form for the year ended December 31, 2006 incorporated by reference into Silver Wheaton's Form 40-F on file with the U.S. Securities and Exchange Commission in Washington, D.C. and available on SEDAR at www.sedar.com. Although Silver Wheaton has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. Silver Wheaton does not undertake to update any forward-looking statements that are incorporated by reference herein, except in accordance with applicable securities laws.

CAUTIONARY LANGUAGE REGARDING RESERVES AND RESOURCES

Readers should refer to the annual information form of Silver Wheaton for the year ended December 31, 2006 and other continuous disclosure documents filed by Silver Wheaton since January 1, 2007 available at www.sedar.com, for further information on mineral Reserves and Resources, which is subject to the qualifications and notes set forth therein as well as for additional information relating to the Company more generally. Mineral Resources which are not Mineral Reserves, do not have demonstrated economic viability.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Resources: These tables use the terms "Measured", "Indicated" and "Inferred" Resources. United States investors are advised that while such terms are recognized and required by Canadian regulations, the United States Securities and Exchange Commission does not recognize them. "Inferred Mineral Resources" have a great amount of uncertainty as to their existence, and as to their 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 other economic studies. United States investors are cautioned not to assume that all or any part of Measured or Indicated Mineral Resources will ever be converted into Mineral Reserves. United States investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists, or is economically or legally mineable.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

YEAR ENDED DECEMBER 31, 2007 (US DOLLARS)

1. DESCRIPTION OF BUSINESS AND NATURE OF OPERATIONS

Silver Wheaton Corp. ("Silver Wheaton" or the "Company") is engaged in the silver mining business.

The Company has entered into five long-term silver contracts with Goldcorp (Luismin mines in Mexico and Penasquito project in Mexico), Lundin Mining (Zinkgruvan mine in Sweden), Glencore (Yauliyacu mine in Peru) and Hellas Gold (Stratoni mine in Greece), whereby Silver Wheaton acquires silver production from the counterparties at an average fixed price of $3.91 per ounce, subject to an inflationary adjustment (Note 4). The Company trades on the Toronto Stock Exchange (TSX) and the New York Stock Exchange (NYSE) under the symbol SLW.

2. ACCOUNTING POLICIES

BASIS OF PRESENTATION

These consolidated financial statements have been prepared in accordance with Canadian generally accepted accounting principles ("Canadian GAAP").

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and its 100% owned subsidiary Silver Wheaton (Caymans) Ltd. ("SW Caymans").

USE OF ESTIMATES

The preparation of financial statements in conformity with Canadian generally accepted accounting principles requires management to make estimates that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant areas where management's judgment is applied are silver contract valuations, depreciation and income taxes. Actual results could differ from those reported.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash, and those short-term money market instruments that are readily convertible to cash with an original term to maturity of less than 90 days.

SILVER INVENTORY

Silver inventory is valued at the lower of average cost and net realizable value.

LONG-TERM INVESTMENTS

Long-term investments in equity securities are classified as available-for-sale because the Company intends to hold the investments for more than one year. Unrealized holding gains and losses related to available-for-sale investments are excluded from net income and are included in other comprehensive income until such gains or losses are realized or an other than temporary impairment is determined to have occurred.

Warrants held by the Company are for long-term investment purposes, however, due to their nature they meet the definition of a derivative and are marked-to-market on a quarterly basis. Mark-to-market gains and losses relating to the warrants are included in net income in the period they occur.

The Company estimates the fair value of financial instruments at the balance sheet date using quoted market prices for available-for-sale securities and a Black-Scholes option pricing model for warrants held.

SILVER INTERESTS

Contracts for which settlement is called for in silver, the amount of which is based on production at the mines, are recorded at cost. The cost of these assets is separately allocated to reserves, resources and exploration potential. The value allocated to reserves is classified as depletable and is depreciated on a unit-of-sale basis over the estimated recoverable proven and probable reserves at the mine corresponding to the specific contract. The value associated with resources and exploration potential is the value beyond proven and probable reserves at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category as a result of the conversion of resources or exploration potential into reserves.

Evaluations of the carrying values of each contract are undertaken each year to determine if estimated undiscounted future net cash flows are less than the carrying value. Estimated undiscounted future net cash flows are calculated using estimated production, sales prices and purchase costs. If it is determined that the future net cash flows from an operation are less than the carrying value then a write-down is recorded with a charge to operations.

INTEREST AND DEBT FINANCING COSTS

Interest and debt financing costs are expensed when they are incurred, unless they are directly attributable to the acquisition or construction of qualifying assets, which are assets that necessarily take a substantial period of preparation for their intended use or sale, in which case they are added to the cost of those assets until such time as the assets are substantially ready for their intended use or sale.

REVENUE RECOGNITION

Revenue from the sale of silver is recognized in the accounts when persuasive evidence of an arrangement exists, title and risk passes to the buyer, collection is reasonably assured and the price is reasonably determinable. Revenue from the sale of silver may be subject to adjustment upon final settlement of estimated metal prices, weights, and assays. Adjustments to revenue for metal prices are recorded monthly and other adjustments are recorded on final settlement.

STOCK-BASED COMPENSATION

The fair value of all stock-based awards granted is estimated using the Black-Scholes model. The compensation cost related to stock options granted to employees and directors is recorded in the consolidated statements of operations.

INCOME TAXES

The future income tax asset and liability method of accounting for income taxes is used. As the Company's operating profit is derived from its subsidiary, SW Caymans, which is incorporated and operated in the Cayman Islands, the Company's profits bear no income tax. Management views the subsidiary's profits as part of its permanent investment in the subsidiary, and it has determined that those profits will be reinvested in foreign jurisdictions for the foreseeable future, therefore, no current income taxes have been recorded.

EARNINGS PER SHARE

Earnings per share calculations are based on the weighted average number of common shares and common share equivalents issued and outstanding during the period. Diluted earnings per share are calculated using the treasury method which requires the calculation of diluted earnings per share by assuming that outstanding share purchase options and warrants, with an average market price that exceeds the average exercise prices of the options and warrants for the year, are exercised and the proceeds are used to repurchase shares of the Company at the average market price of the common shares for the period.

FOREIGN CURRENCY TRANSLATION

Foreign currency monetary assets and liabilities are translated into United States dollars at the exchange rates prevailing at the balance sheet date. Non-monetary assets denominated in foreign currencies are translated using the rate of exchange at the transaction date. Foreign currency transactions are translated at the United States dollar rate prevailing on the transaction dates. Foreign exchange gains and losses are included in the determination of earnings except for the foreign exchange gains and losses on the Company's available for sale investments which are included in the determination of Comprehensive Income.

CHANGES IN ACCOUNTING POLICIES

Financial Instruments

The Company adopted the provisions of Sections 3855, Financial Instruments - Recognition and Measurement, 3861 - Financial Instruments - Disclosure and Presentation, 1530 - Comprehensive Income, 3865 - Hedges and 3251 - Equity, on January 1, 2007 which address the classification, recognition and measurement of financial instruments in the financial statements and the inclusion of other comprehensive income ("OCI"). As a result of adopting these new standards, the Company recorded a non-cash increase of $39.5 million to opening long-term investments, a non-cash increase of $3.3 million to future income tax liability and a non-cash pre-tax adjustment of $37.7 million ($31.1 million net of tax) as a one-time cumulative effect of a change in accounting policy in opening accumulated other comprehensive income. In addition, the Company recorded a non-cash increase of $5.1 million to opening retained earnings to recognize the value of income tax losses not previously recognized and to record the cumulative effect of the change in accounting policy as it relates to warrants held by the Company.

Under Section 3855, share purchase warrants held by the Company are classified as derivatives and marked-to-market each reporting period. As a result, the Company realized a non-cash increase of $1.9 million to opening long-term investments and retained earnings as a one-time cumulative effect of a change in accounting policy on January 1, 2007.

Also under Section 3855, the Company adopted a policy to expense debt financing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset when they are incurred and as a result the Company recorded a non-cash adjustment to decrease opening retained earnings by $0.2 million to eliminate the opening balance of debt financing costs that were capitalized and amortized under the Company's previous accounting policy.

The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate their fair values due to their short term nature. Unless otherwise noted, it is management's opinion that the Company is not exposed to significant interest, currency or credit risk arising from these financial instruments.

FUTURE ACCOUNTING CHANGES

Capital Disclosures

The CICA issued a new accounting standard, Section 1535, Capital Disclosures ("Section 1535"), which requires the disclosure of both qualitative and quantitative information that enables users of financial statements to evaluate the entity's objectives, policies and processes for managing capital. Section 1535 specifies the disclosure of (i) an entity's objectives, policies and processes for managing capital; (ii) quantitative data about what the entity regards as capital; (iii) whether the entity has complied with any capital requirements; and (iv) if it has not complied, the consequences of such non-compliance. This new standard became effective for the Company on January 1, 2008.

Financial Instruments

The CICA issued two new accounting standards, Section 3862, Financial Instruments - Disclosures ("Section 3862"), and Section 3863, Financial Instruments - Presentation ("Section 3863"), which replace Handbook Section 3861, Financial Instruments - Disclosure and Presentation, revising and enhancing its disclosure requirements and carrying forward unchanged its presentation requirements for financial instruments. Sections 3862 and 3863 place increased emphasis on disclosures about the nature and extent of risks arising from financial instruments and how the entity manages those risks. These new standards will become effective for the Company for periods beginning on or after October 1, 2007.

Impact of adopting Sections 1535, 3862 and 3863

The Company is currently analyzing the requirements of these new standards.

The value allocated to reserves is classified as depletable and is depreciated on a units-of-sale basis over the estimated recoverable proven and probable reserves at the mine. The value associated with resources and exploration potential is the value beyond proven and probable reserves allocated at acquisition and is classified as non-depletable until such time as it is transferred to the depletable category as a result of the conversion of resources or exploration potential into reserves.

LUISMIN

On October 15, 2004, SW Caymans entered into an agreement (amended on March 30, 2006) to acquire all of the silver produced by Goldcorp's Luismin mining operations in Mexico (owned at the date of the transaction) for a period of 25 years. Total consideration, including consideration issued as part of the March 30, 2006 amendment, was $36.7 million in cash up front, a $20 million promissory note and 126 million common shares of the Company. In addition, a per ounce cash payment of the lesser of $3.95 and the prevailing market price is due (subject to an inflationary adjustment on October 15 of each year).

On February 14, 2008, Goldcorp sold its entire 48% interest in Silver Wheaton by way of a secondary offering, as described in Note 14.

ZINKGRUVAN

In December, 2004, SW Caymans entered into an agreement to acquire all of the silver produced by Lundin Mining Corporation's Zinkgruvan mine in Sweden for an upfront payment of $50 million in cash, 6 million Silver Wheaton common shares and 30 million Silver Wheaton common share purchase warrants (each warrant grants the holder the right to purchase 0.20 of one of the Company's common shares). In addition, a per ounce cash payment of the lesser of $3.96 and the prevailing market price is due (subject to an inflationary adjustment on December 8 each year).

YAULIYACU

On March 23, 2006, SW Caymans entered into an agreement with Glencore International AG ("Glencore") to acquire up to 4.75 million ounces of silver per year, for a period of 20 years, based on the production from Glencore's Yauliyacu mining operations in Peru. The upfront payment was $285 million, comprised of $245 million in cash and a $40 million promissory note which was paid in full on May 31, 2006. In addition, a cash payment of $3.90 per ounce of silver delivered under the contract is due (subject to an inflationary adjustment commencing in 2009). In the event that silver produced at Yauliyacu in any year totals less than 4.75 million ounces, the amount sold to Silver Wheaton in subsequent years will be increased to make up for the shortfall, so long as production allows.

During the term of the contract, Silver Wheaton has a right of first refusal on any future sales of silver streams from the Yauliyacu mine and a right of first offer on future sales of silver streams from any other mine owned by Glencore at the time of the initial transaction. In addition, Silver Wheaton also has an option to extend the 20 year term of the silver purchase agreement in five year increments, on substantially the same terms as the existing agreement, subject to an adjustment related to silver price expectations at the time and other factors.

STRATONI

On April 23, 2007, SW Caymans entered into an agreement with Hellas Gold S.A. ("Hellas Gold"), a subsidiary of European Goldfields Ltd. ("European Goldfields") to acquire all of the silver produced from Hellas Gold's Stratoni mining operations in Greece for the life of mine. Silver Wheaton made an upfront cash payment of $57.5 million. In addition, a per ounce cash payment of the lesser of $3.90 and the prevailing market price is due (subject to an inflationary adjustment commencing in 2010), for silver delivered under the contract.

During the term of the contract, Silver Wheaton will have a right of first refusal on any future sales of silver streams from any other mine owned by European Goldfields or Hellas Gold.

ROSEMONT

On December 20, 2007, the Company signed a binding letter agreement to acquire between 45% and 90% of silver produced by Augusta Resource Corporation's ("Augusta") Rosemont Copper Project in Arizona for the life of mine. Augusta must elect the percentage of life of mine silver subject to the transaction, which will be between a minimum of 45% and a maximum of 90%, on or before March 31, 2008.

Subject to the finalization of the transaction structure, including tax considerations, Silver Wheaton will pay an upfront cash payment ranging in value from $135 million to $165 million to acquire 45% of the payable silver, and $240 million to $320 million to acquire 90% of the payable silver, produced for the life of mine.

The upfront payment will be made on a drawdown basis to fund construction of the mine as construction milestones are achieved. Silver Wheaton will not be required to pay any further ongoing per ounce payments for silver delivered from Rosemont and is not required to fund or contribute to ongoing capital expenditures, including expansion scenarios. Augusta will provide a completion guarantee that the Rosemont mine will be constructed with certain minimum production criteria by certain dates.

The transaction is subject to (a) Augusta receiving all necessary permits to construct and operate a mine in accordance with their August 2007 Rosemont Feasibility Study, (b) Augusta having entered into committed arrangements for sufficient financing to construct and operate the mine, and (c) execution by the parties of definitive agreements on or before June 30, 2008 as well as receipt of any required regulatory approvals and third-party consents. Augusta expects production at the Rosemont project to start in late 2010 with an average of 2.7 million ounces of silver produced each year over the life of mine, currently expected to be a minimum of 18 years.

5. PROMISSORY NOTE

On March 30, 2006, as partial consideration for amendments made to the Luismin silver purchase contract, the Company issued a non-interest bearing $20 million promissory note to Goldcorp, due on March 30, 2007. The promissory note was repaid in full during March 2007.

6. BANK DEBT

On July 24, 2007, the Company cancelled its undrawn $25 million revolving loan facility and entered into a credit agreement with the Bank of Nova Scotia and BMO Capital Markets, as co-lead arrangers and administrative agents, to borrow $200 million under a non revolving term loan (the "Term Loan") and up to $300 million under a revolving term loan (the "Revolving Loan"). The Revolving Loan is for a period of 7 years and the Term Loan is to be repaid in equal installments over a period of 7 years, however, prepayments are allowed at any time. Silver Wheaton has committed to pay down the Revolving Loan, within 61 days after the end of each fiscal quarter, by an amount equal to 90% of the cash flows reported for the quarter. The Revolving Loan can be drawn down at any time to finance acquisitions or investments. In order to fund the Penasquito transaction, the Term Loan was drawn in full and the Revolving Loan was drawn in the amount of $246 million.

Amounts drawn incur interest at LIBOR plus 0.875% to 1.75% per annum dependent upon the Company's leverage ratio. Undrawn amounts are subject to a 0.2% to 0.45% per annum commitment fee dependent on the Company's leverage ratio. Under the credit agreement, the Company is required to maintain a debt service coverage ratio greater than or equal to 1.25 : 1, a Leverage Ratio less than or equal to 5 : 1 (decreasing to 4 : 1 on September 30, 2008 and to 3.5 : 1 on September 30, 2009), and a Tangible Net Worth greater than 80% of the Tangible Net Worth at June 30, 2007 plus 50% of Net Income for each fiscal quarter thereafter. Both the Term Loan and the Revolving Loan are secured against the Company's assets, including the Company's silver interests. The Company has paid $2.5 million in debt financing costs relating to the credit agreement which was capitalized to the cost of the Penasquito contract. During 2007, the Company repaid $7.1 million and $19.0 million of the balances outstanding on the Term Loan and Revolving Loan, respectively.

(C) SHARE PURCHASE OPTIONS

The Company has established a share purchase option plan whereby the Company's board of directors may, from time to time, grant options to directors, employees or consultants. The maximum term of any option may be ten years, but generally options are granted for five years. The exercise price of an option is not less than the closing price on the TSX on the last trading day preceding the grant date.

Stock-based compensation expense during 2007 included $2.6 million (2006 - $1.7 million) of amortization of the fair value of share purchase options issued. During 2007, 945,000 options were issued with a fair market value of $4.1 million which was determined using the Black-Scholes option valuation method assuming no dividends are to be paid, a weighted average volatility of the Company's share price of 48%, an annual risk-free interest rate of 4.1% and expected lives of 2.9 years.

At December 31, 2007 there were 2,745,000 options available for grant under the plan.
