Silver Wheaton First Quarter Earnings Increase 165% to US$13.8 Million

Vancouver, British Columbia – Silver Wheaton Corp. (TSX,AMEX:SLW) is pleased to report record first quarter net earnings and operating cash flows of US$13.8 million and US$13.9 million respectively (US$0.07 per share).

HIGHLIGHTS

·

Record net earnings of $13.8 million ($0.07 per share) from the sale of 2.7 million ounces of silver, compared to $5.2 million ($0.03 per share) from the sale of 2.3 million ounces of silver in 2005.

·

Record operating cash flows of $13.9 million (2005 - $5.2 million).

·

In March, 2006, Silver Wheaton amended its silver purchase contract with Goldcorp, increasing the minimum number of ounces to be delivered by Goldcorp over the 25 year period by 100 million ounces, to 220 million ounces, and waiving any capital expenditure contributions previously required to be paid by Silver Wheaton.  Total consideration paid by Silver Wheaton was $136 million.

·

In March, 2006, the Company entered into an agreement with Glencore International AG, to purchase 4.75 million ounces of silver per year for a period of 20 years, based on the production from their Yauliyacu mining operations in Peru. Total consideration paid was $285 million.  In addition, a cash payment of $3.90 per ounce of silver delivered under the contract is due, subject to an inflationary adjustment.

·

In March, 2006, the Company announced a Cdn$175 million public offering of 14.6 million common shares at a price of Cdn$12.00 per share, on a bought deal basis.  The underwriters have an option to increase the size of the offering to approximately Cdn$200 million.  The offering is expected to close during April, 2006, at which time the proceeds will be used to repay debt.

“These results are spectacular, obviously assisted by continuing strong silver prices” said Eduardo Luna, Chairman.  “We expect our second quarter to be even better, as a result of silver sales starting up under our new Yauliyacu silver contract.”

A conference call will be held Thursday, April 20, 2006 at 11:00 am (EDT) to discuss these results. You may join the call by dialling toll free 1-877-888-4605 or (416) 695-6622 for calls from outside of Canada and the US.

Silver Wheaton Corp. will hold an Annual Shareholders Meeting in Room 206 of the Metro Toronto Convention Centre, 225 Front Street West, Toronto, Ontario on Thursday, April 20, 2006 at 4:00 p.m. (EDT).

Silver Wheaton is the only public mining company with 100% of its revenue from silver production.  The Company expects to have annual silver sales of approximately 15 million ounces in 2006, increasing to 20 million ounces by 2009 and thereafter.  Silver Wheaton is unhedged and well positioned for further growth.

OVERVIEW

Silver Wheaton Corp. (“Silver Wheaton” or the “Company”) is a growth-oriented silver company, and is the only mining company with 100% of its revenue from silver production. The Company’s goal is to be recognized as the largest, most profitable and best managed pure silver company in the world.

The Company has entered into three long-term silver purchase contracts with Goldcorp (Luismin mines in Mexico), Lundin Mining (Zinkgruvan mine in Sweden) and Glencore (Yauliyacu mine in Peru), whereby Silver Wheaton acquires silver production from the counter-parties at a fixed price of $3.90 per ounce, subject to adjustment.  As a result, the primary drivers behind the Company’s financial results are the price of silver and the volume of silver production at the various mines.

The Company expects to have annual silver sales of approximately 15 million ounces in 2006, increasing to 20 million ounces by 2009 and thereafter.

SUMMARIZED FINANCIAL RESULTS

The year end of the Company was changed from August 31 to December 31, during 2004.  As a result, comparative figures include the four months ended December 31, 2004.

Luismin

On October 15, 2004, a 100% subsidiary of the Company, Silver Wheaton (Caymans) Ltd. (“SW Caymans”), entered into an agreement (amended on March 30, 2006) to purchase all of the silver produced by Goldcorp’s Luismin mining operations in Mexico for a period of 25 years, for an upfront payment of $36.7 million (Cdn$46.0 million) in cash and 108 million common shares of the Company. 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 2007).  Under this agreement, Luismin was required to deliver a minimum of 120 million ounces over the 25 year period following the contract date, and Silver Wheaton was obligated to pay 50% of any capital expenditures made by Luismin at its mining operations in excess of 110% of the projected capital expenditures outlined in th e contract.

On March 30, 2006, Goldcorp and Silver Wheaton amended the silver purchase contract, increasing the minimum number of ounces of silver to be delivered over the 25 year period by 100 million ounces, to 220 million ounces, and waiving any capital expenditure contributions previously required to be paid by Silver Wheaton.  In consideration for these amendments, Silver Wheaton issued to Goldcorp 18 million common shares and a $20 million non-interest bearing promissory note due on March 30, 2007.  As a result, at March 31, 2006, Goldcorp owned 62% of the Company’s common shares.

The amendment to the silver purchase contract was made in connection with Goldcorp’s plans to substantially increase its investment in exploration and development at its San Dimas mine in Mexico.  As a result of the planned exploration and development at San Dimas, Silver Wheaton and Goldcorp anticipate that additional silver sales will aggregate more than 100 million ounces over the remaining 24 year term of the silver purchase agreement.  It is projected that Luismin’s annual silver production will approximate 9.5 million ounces in 2006, increasing to 13 million ounces by 2009 and thereafter.

During the three months ended March 31, 2006, SW Caymans purchased 2.2 million ounces (2005 – 2.0 million ounces) of silver under the contract at a total cash cost of $3.90 per ounce, and sold it for an average price of $9.72 per ounce (2005 - $6.93 per ounce).   The Company’s cash flows and net earnings under the Luismin silver contract for the three months ended March 31, 2006 were $12.6 million (2005 - $5.8 million) and $11.9 million (2005 - $5.3 million), respectively.

At December 31, 2005, the Luismin mines had proven and probable reserves of 45.4 million ounces of silver and inferred resources of 188.4 million ounces of silver, an increase of 12.7% and 29.4% respectively, compared to the reserves and resources at December 31, 2004, despite production during 2005 of 7.7 million ounces of silver.  Luismin has historically converted resources into reserves at a rate of approximately 90%.  

The results of the Luismin mine operations for the three months ended March 31, 2006 are shown below:

Zinkgruvan

On December 8, 2004, SW Caymans entered into an agreement to purchase all of the silver produced by Lundin Mining’s Zinkgruvan mining operations in Sweden (“Zinkgruvan”) for the life of mine. During the three months ended March 31, 2006, SW Caymans purchased 0.5 million ounces (2005 – 0.3 million ounces) of silver under the contract at a total cash cost of $3.90 per ounce, and sold it for an average price of $9.20 per ounce (2005 - $6.86 per ounce).   The Company’s cash flows and net earnings under the Zinkgruvan silver contract for the three months ended March 31, 2006 were $0.9 million (2005 - $0.5 million) and $1.8 million (2005 - $0.4 million), respectively.

As at December 31, 2005, Zinkgruvan had proven and probable silver reserves of 25.8 million ounces, measured and indicated silver resources of 6.8 million ounces and inferred silver resources of 29.4 million ounces.  The Zinkgruvan mine is expected to produce approximately 2 million ounces of silver annually for a minimum of 20 years, and is one of the lowest cost zinc mines in the world. The mine is located in south-central Sweden and has been in production on a continuous basis since 1857.

Yauliyacu

On March 23, 2006, SW Caymans entered into an agreement with Glencore to purchase 4.75 million ounces of silver per year, for a period of 20 years, based on the production from their Yauliyacu mining operations in Peru. Total consideration paid was $285 million, comprised of $245 million in cash and a $40 million promissory note due on July 21, 2006.  In addition, a cash payment of $3.90 per ounce of silver delivered under the contract is due, subject to an inflationary adjustment.

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 from any other mine currently owned by Glencore.  In addition, Silver Wheaton has an option to extend the 20 year term of the silver purchase 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, 2005, Yauliyacu had proven and probable silver reserves of 12.9 million ounces, measured and indicated silver resources of 52.2 million ounces and inferred silver resources of 64.7 million ounces.  Delivery of silver under the Yauliyacu silver contract is expected to begin in May 2006.

General and administrative expenses totaled $518,000 during the three months ended March 31, 2006 (2005 – $415,000), including $70,000 (2005 - $159,100) paid to Goldcorp for management and administrative services at cost. Also included in general and administrative expenses were professional service fees, including legal, accounting and audit fees, totaling $68,000 (2005 - $127,600), salary expenses of $105,000 (2005 - $nil), and investor relations and regulatory fees of $110,000 (2005 - $51,000). Total general and administrative expenses for the three months ended March 31, 2006 were higher than for the three months ended March 31, 2005, primarily due to the increased investor relations and regulatory fees and increased salary expenses.

Interest expense totaled $202,000 during the three months ended March 31, 2006 (2005 - $nil) due to financing used to fund the Yauliyacu transaction, including bank debt of $125 million and the $40 million promissory note due to Glencore.  Debt financing costs of $1,029,000 were incurred during the quarter to obtain the bank debt.  Of these, $254,000 were amortized to income during the period.

The non-cash stock based compensation expense has been estimated using the Black-Scholes option valuation method to determine the fair value of the share purchase options granted.   

Project evaluation expenses of $33,000 (2005 - $8,000) were incurred in pursuing additional silver acquisition opportunities.  It is anticipated that project evaluation expenses will continue during 2006.

Interest income during the three months ended March 31, 2006 of $1,140,000 (2005 - $77,000) was the result of interest earned on cash balances held in short-term money market instruments.

During the three months ended March 31, 2006, a foreign exchange gain of $30,000 (2005 – loss of $104,000) was realized, as a result of the Company holding a portion of its cash balances in Canadian dollars, while the Canadian dollar increased in value against the US dollar (the Company’s functional currency).

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 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 three months ended March 31, 2006, the Company’s total cash costs were $3.90 per ounce of silver.

LIQUIDITY AND CAPITAL RESOURCES

During the three months ended March 31, 2006, the Company generated operating cash flows of $13.9 million (2005 - $5.2 million).  In the opinion of management, cash flows from operations are sufficient to support the Company’s normal operating requirements on an ongoing basis.

Yauliyacu silver purchase contract

On March 23, 2006, the Company entered into an agreement with Glencore to purchase 4.75 million ounces of silver per year, for a period of 20 years, based on the production from their Yauliyacu mining operations in Peru. Total consideration paid was $285 million, comprised of $245 million in cash and a $40 million promissory note due on July 21, 2006.  In addition, a cash payment of $3.90 per ounce of silver delivered under the contract is due, subject to an inflationary adjustment.

Luismin silver purchase contract amendment

On March 30, 2006, Goldcorp and Silver Wheaton amended their existing silver purchase contract, increasing the minimum number of ounces of silver to be delivered by Goldcorp over the 25 year contract period by 100 million ounces, to 220 million ounces, and waiving any capital expenditure contributions previously required to be paid by Silver Wheaton.  In consideration for these amendments, Silver Wheaton issued to Goldcorp 18 million common shares and a $20 million non-interest bearing promissory note due on March 30, 2007.

Bank debt

In March 2006, the Company entered into a credit agreement with the Bank of Nova Scotia, as lead arranger and administrative agent, to borrow $100 million under a non revolving term loan (the “Term Loan”) and $25 million under a revolving term loan (the “Revolving Loan”) in order to partially finance the acquisition of the Yauliyacu silver purchase contract.  The Revolving Loan is for a period of five years and the Term Loan is to be repaid in equal installments over a period of four years, however, prepayments are allowed at any time.  On March 31, 2006, the Company repaid $5 million of the outstanding balance due under the Revolving Loan.

Working capital

At March 31, 2006 the Company had cash and cash equivalents of $8.4 million (December 31, 2005 – $117.7 million) and a working capital deficit of $74.4 million, which includes the current portion of bank debt and promissory notes due, totaling $85.0 million, relating to the March, 2006 acquisition of the Yauliyacu silver contract and the amendment of the Luismin silver contract.  

On March 27, 2006, the Company announced that it had entered into an agreement with GMP Securities L.P. and a syndicated of underwriters, which had agreed to purchase on a bought deal basis, 14.6 million common shares of Silver Wheaton at a purchase price of Cdn$12.00 per share, for aggregate gross proceeds of approximately Cdn$175 million.  The underwriters have an option to purchase up to an additional 2.0 million shares at the issue price prior to the closing of the offering.  In the event that the option is exercised in its entirety, the aggregate gross proceeds of the offering will be approximately Cdn$200 million.

The financing is expected to close during April, 2006, at which time Silver Wheaton plans to use the net proceeds to pay $40 million due to Glencore International AG under a promissory note, and to repay bank debt associated with its recent silver acquisition from Glencore.

Contractual obligations

In connection with the Luismin and Zinkgruvan silver purchase 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 $3.90 and the then prevailing market price, subject to adjustment.  This inflationary adjustment, which will begin in 2007, is intended to reflect the effects of inflation on operating costs, and is subject to a minimum of 0.4% and a maximum of 1.65% per annum.  In connection with the Yauliyacu silver purchase contract, the Company has committed to purchase 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 adjustment.  This inflationary adjustment, which will begin in 2009, is intended to reflect the effects of inflation on operating costs, and is subject to a minimum of 1.0% and a maximum of 1.65% per annum. &nb sp;

Share capital

During the three months ended March 31, 2006, the Company received cash proceeds of $3.3 million (2005 - $nil) from the exercise of 1,176,034 (2005 – nil) share purchase options at a weighted average exercise price of Cdn$3.26 per option.  As of April 19, 2006, there were 203,351,134 outstanding common shares, 4,461,666 share purchase options and 165,573,500 share purchase warrants, which are convertible into 39,364,700 shares.

RELATED PARTY TRANSACTIONS

At March 31, 2006, Goldcorp owned 62% of the Company’s outstanding common shares.  During the three months ended March 31, 2006, the Company purchased 2.2 million ounces (2005 – 2.0 million ounces) of silver from a subsidiary of Goldcorp at a price of $3.90 per ounce, for total consideration of approximately $8.5 million (2005 - $7.7 million).  

On March 30, 2006, Silver Wheaton and Goldcorp amended the Luismin silver purchase agreement, as described elsewhere in this Management’s Discussion and Analysis.

The Company has an agreement with Goldcorp whereby Goldcorp provides management and administrative services at cost.  During the three months ended March 31, 2006, total management fees paid to Goldcorp were $70,000 (2005 - $159,100). This agreement allows for cancellation with 30 days notice at any time.

In addition, during the three months ended March 31, 2006, payments made by Goldcorp on the Company’s behalf totalled approximately $47,000 (2005 - $38,100).  At March 31, 2006, the Company owed Goldcorp $117,000 (2005 - $556,900).

OVERSIGHT ROLE OF THE AUDIT COMMITTEE

The Audit Committee reviews, with management and the external auditors, the Company’s quarterly Management’s Discussion and Analysis and related consolidated financial statements and approves the release of such information to shareholders.  For each audit or quarterly review, the external auditors prepare a report for members of the Audit Committee summarizing key areas, significant issues and material control weaknesses encountered, if any.

FINANCIAL INSTRUMENTS

During the three months ended March 31, 2006, the Company has used a mixture of cash and long-term debt to maintain an appropriate capital structure, ensuring the liquidity 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 and therefore, in the normal course of business, is inherently exposed to currency, interest rate and commodity price fluctuations.

OUTLOOK

The Company expects to have annual silver sales of approximately 15 million ounces in 2006, increasing to 20 million ounces by 2009 and thereafter.

The Company is unhedged and actively pursuing further growth opportunities, either by way of entering into long-term silver purchase contracts, or by acquiring silver exploration, development or production assets.

BASIS OF PRESENTATION

These unaudited interim consolidated financial statements have been prepared in accordance with Canadian generally accepted accounting principles (“Canadian GAAP”) for interim financial information and they follow the same accounting policies and methods of application as the audited consolidated financial statements of the Company for the year ended December 31, 2005 except as noted below. These unaudited interim consolidated financial statements do not include all the information and note disclosure required by generally accepted accounting principles for annual financial statements and therefore should be read in conjunction with the most recent annual audited consolidated financial statements.

In the opinion of management, all adjustments (including reclassifications and normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows at March 31, 2006 and for all periods presented, have been made.  The interim results are not necessarily indicative of results for a full year.

Luismin silver purchase contract

On October 15, 2004, the Company entered into a twenty five year agreement to purchase all of the silver produced by Goldcorp’s Luismin mining operations in Mexico, for an upfront payment of $36.7 million (Cdn$46.0 million) in cash and 108 million common shares of the Company. 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 2007).  Under this agreement, Luismin was required to deliver a minimum of 120 million ounces over the 25 year period following the contract date, and Silver Wheaton was obligated to pay 50% of any capital expenditures made by Luismin at its mining operations in excess of 110% of the projected capital expenditures outlined in the contract.

On March 30, 2006, Goldcorp and Silver Wheaton amended the silver purchase contract, increasing the minimum number of ounces of silver to be delivered over the 25 year period by 100 million ounces, to 220 million ounces, and waiving any capital expenditure contributions previously required to be paid by Silver Wheaton.  In consideration for these amendments, Silver Wheaton issued to Goldcorp 18 million common shares, valued at the February 13, 2006 closng price of $6.42 per share, and a $20 million non-interest bearing promissory note due on March 30, 2007.    As a result, at March 31, 2006, Goldcorp owned 62% of the Company’s common shares.

The allocation of the total purchase price is summarized in the table below:

Yauliyacu silver purchase contract

On March 23, 2006, the Company entered into an agreement to purchase 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, for an upfront payment of $285 million, comprised of $245 million in cash and a $40 million promissory note (Note 4). 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 currently owned by Glencore.  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.

The allocation of the purchase price is summarized in the table below:

PROMISSORY NOTES

On March 23, 2006, as partial consideration for entering into the Yauliyacu silver purchase contract (Note 3), the Company issued a $40 million promissory note to Glencore, bearing interest at 3% per annum and due on July 21, 2006 (Note 10).  

On March 30, 2006, as partial consideration for amendments made to the Luismin silver purchase agreement (Note 3), the Company issued a non-interest bearing $20 million promissory note to Goldcorp, due on March 30, 2007.  

Both of these promissory notes were outstanding at March 31, 2006.

5.

BANK DEBT

In March 2006, the Company entered into a credit agreement with the Bank of Nova Scotia, as lead arranger and administrative agent, to borrow $100 million under a non revolving term loan (the “Term Loan”) and $25 million under a revolving loan (the “Revolving Loan”).  The Revolving Loan is for a period of five years and the Term Loan is to be repaid in equal instalments over a period of four years, however, prepayments are allowed at any time.   The interest rate on each of these loans is based on LIBOR plus a spread determined by 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 and a Leverage Ratio less than or equal to 3.50 : 1.  Both the Term Loan and the Revolving loan are secured against the Company& #146;s assets including the Luismin, Zinkgruvan and Yauliyacu silver purchase contracts.  Total debt financing costs were $1,029,000, of which $254,000 was amortized to income during the period.  On March 31, 2006, the Company repaid $5 million of the outstanding balance due under the Revolving Loan.

In March, 2006, the Company announced a Cdn$175 million public offering of 14.6 million common shares at a price of Cdn$12.00 per share, on a bought deal basis.  The underwriters have an option to increase the size of the offering to approximately Cdn$200 million, prior to the closing of the offering.  The offering is expected to close during April, 2006, at which time the proceeds will be used to repay debt (Note 10).

SUBSEQUENT EVENT

On March 27, 2006, the Company announced that it had entered into an agreement with GMP Securities L.P. and a syndicate of underwriters, which agreed to purchase on a bought deal basis, 14.6 million common shares of Silver Wheaton at a purchase price of Cdn$12.00 per share, for aggregate gross proceeds of approximately Cdn$175 million.  The underwriters also have the option to purchase up to an additional 2.0 million shares at the issue price prior to the closing of the offering.  In the event that the option is exercised in its entirety, the aggregate gross proceeds of the offering will be approximately Cdn$200 million.

The financing is expected to close during April, 2006, at which time Silver Wheaton plans to use the net proceeds to pay $40 million due to Glencore International AG under a promissory note (Note 4), and to repay bank debt associated with its recent silver acquisition from Glencore (Note 3).
