The company operates as a precious metals streaming entity, deriving 100% of its operating revenue from silver production. The filing primarily announces a significant update to mineral reserves and resources at the Peñasquito Project in Zacatecas, Mexico, based on data released by partner Goldcorp Inc.
Key Financial and Operational Metrics
The filing does not provide specific revenue, profit, cash flow, or debt figures for the reporting period. Key operational metrics include:
- Production Outlook: Expected annual silver sales of approximately 15 million ounces in 2007, increasing to 23 million ounces by 2009.
- Hedging Status: The company is unhedged.
- Peñasquito Project (25% Attributable Share):

- Total Company Reserves: Attributable proven and probable silver reserves increased by 25% to 362.2 million ounces.
- Total Company Resources: Attributable measured and indicated silver resources increased by 34% to 162.5 million ounces.
Material Changes Versus Prior Period
The primary material change is the substantial upgrade in the Peñasquito Project's reserve and resource estimates, driven by assays from 240 additional drill holes completed since June 2006.
- Reserve Increase: Total proven and probable silver reserves at Peñasquito rose by 50% to 864 million ounces (Goldcorp total), translating to a 25% increase in Silver Wheaton's total attributable reserves.
- Resource Increase: Measured and indicated resources at Peñasquito rose by 67% to 413 million ounces (Goldcorp total), translating to a 34% increase in Silver Wheaton's total attributable resources.
- Project Optimization: Goldcorp is analyzing an increase in mill capacity from 100,000 tonnes per day to 130,000 tonnes per day based on the updated reserves.
Guidance, Outlook, and Risks
Outlook and Management Commentary: Management expressed excitement regarding the expansion potential of the Peñasquito ore-body. Construction remains on schedule for initial heap leaching in 2008 and the start-up of the first milling circuit by late 2009. Silver Wheaton expects to close the silver purchase agreement for Peñasquito in August 2007. The company will not contribute to capital expenditures at the project.
Risks and Contingencies:
- Operational Control: Silver Wheaton has no control over the mining operations from which it purchases silver.
- Forward-Looking Statements: Future production estimates and project timelines are subject to risks including exploration results, economic evaluations, and changes in project parameters.
- Resource Classification: The filing includes a cautionary note for U.S. investors that "Measured," "Indicated," and "Inferred" resources are not recognized by the SEC and may not be economically or legally mineable.
- Glencore Agreement: Production at the Yauliyacu Mine in excess of 4.75 million ounces per year is credited to Glencore, potentially limiting Silver Wheaton's access to a portion of reserves.
Investor Verification Checklist
- Verify the timing of the August 2007 closing for the Peñasquito silver purchase agreement.
- Confirm the schedule for the revised capital and economic review regarding the proposed 130,000 tonnes per day mill capacity increase.
- Monitor the progress of the 2008 heap leach start-up and late 2009 milling start-up dates.
- Review the impact of the unhedged position on future earnings given silver price volatility.
- Assess the risk that "Inferred" resources at Peñasquito and other sites may not be upgraded to reserves.
