Business Context and Reporting Period
This Form 6-K filing by Silver Wheaton Corp. (now Wheaton Precious Metals Corp.) reports a material change dated June 25, 2007, filed on July 4, 2007. The company operates as a precious metals streaming entity, purchasing silver at a fixed price from mining partners. The filing details a significant upgrade in reserves and resources for the Peñasquito Project in Zacatecas, Mexico, operated by Goldcorp Inc., from which Silver Wheaton holds a 25% silver stream.
Key Financial and Operational Metrics
The filing focuses on mineral reserve and resource updates rather than traditional financial statements (revenue, profit, cash flow). Key operational metrics include:
- Attributable Silver Reserves: Silver Wheaton's proven and probable silver reserves increased by 25% to 362 million ounces.
- Attributable Silver Resources: Measured and indicated silver resources increased by 34% to 162 million ounces.
- Peñasquito Project Total Reserves: Goldcorp's total proven and probable silver reserves increased by 50% to 864 million ounces.
- Peñasquito Project Total Resources: Measured and indicated resources increased by 67% to 413 million ounces.
- Capital Expenditures: Silver Wheaton will not be responsible for capital contributions toward the Peñasquito project.
Material Changes Versus Prior Period
Compared to the previous reserve update in June 2006, the Peñasquito Project has seen substantial growth driven by assays from an additional 240 drill holes. The specific changes for Silver Wheaton's attributable portion are:
- Reserve Increase: Attributable proven and probable reserves rose from approximately 290 million ounces (implied) to 362 million ounces.
- Resource Increase: Attributable measured and indicated resources rose to 162 million ounces.
- Mill Capacity Optimization: Goldcorp is analyzing an increase in mill capacity from the feasibility study plan of 100,000 tonnes per day to a total of 130,000 tonnes per day (two circuits of 65,000 tonnes each).
Outlook, Management Commentary, and Risks
Project Timeline and Construction:
- Initial heap leaching of oxide ore is scheduled for 2008.
- Start-up of the first milling and flotation circuit is expected by late 2009.
- Construction progress is on schedule, with crusher foundation concrete poured and road/power line installations expected later in the summer of 2007.
- Recent drilling in the Manto-Skarn zone has encountered high-grade material, highlighting potential for deeper underground mining concurrent with open-pit operations.
- A revised capital schedule and economic review regarding the increased mill capacity is expected prior to year-end 2007.
- Transaction Closing: The silver purchase agreement for Peñasquito is expected to close in August 2007; delays could impact revenue recognition.
- Forward-Looking Statements: Actual results may differ materially due to risks related to international operations, lack of control over mining operations, and exploration results.
- 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 do not have demonstrated economic viability.
Investor Verification Checklist
- Verify the closing of the Peñasquito silver purchase agreement in August 2007.
- Monitor the revised capital schedule and economic review for the proposed 130,000 tonnes per day mill capacity.
- Track construction milestones for the 2008 heap leach start and late 2009 mill start-up.
- Review future drill results from the Manto-Skarn zone to assess the viability of underground mining extensions.
- Confirm that Silver Wheaton remains exempt from capital expenditure contributions for the project.
