Material Changes Versus Prior Period
The Hamlet deposit has seen a substantial increase in reported resources compared to the 2009 financial year declaration:
- Prior Estimate (2009): 2.1 Mt at 3.65 g/t for 251,000 ounces.
- Current Estimate (May 2010): 6.62 Mt at 4.86 g/t for 1.03 million ounces.
- Change: The total resource volume increased by approximately 214%, and the gold content increased by approximately 310%.
- Camp Endowment: The Argo-Athena camp now has an estimated endowment of about 4 Moz, following the discovery of Athena and the expansion of Hamlet.
Outlook, Management Commentary, and Risks
Management Commentary: CEO Nick Holland highlighted the milestone as a credit to the near-mine exploration team, emphasizing the potential of the Argo-Athena camp.
Outlook and Timeline:
- Feasibility Study: Drilling to support a feasibility study is underway.
- Construction Decision: Planned for the first half of calendar 2011.
- Athena Mine: The nearby Athena underground mine is on schedule for full production in mid-2011. Its infrastructure is positioned to provide potential underground access to Hamlet, enabling rapid development.
- Resource Status: The Hamlet deposit remains open at depth.
Risks and Contingencies:
- SEC Disclosure Standards: The filing notes that terms like "Mineral Resource" are prohibited in SEC filings unless the deposit is economically and legally extractable. US investors are directed to the Form 20-F for compliant disclosures.
- Price Assumptions: The pit shell optimization is based on a gold price of US$1,150/oz.
Key Facts for Investor Verification
- Verify the economic viability of the Hamlet deposit in the upcoming feasibility study scheduled for 2011.
- Confirm the integration of Hamlet development with the Athena mine infrastructure and the mid-2011 production timeline for Athena.
- Review the Form 20-F for SEC-compliant reserve definitions, as this 6-K uses SAMREC Code terminology which may differ from US NI 43-101 standards.
- Monitor the progress of the 41,900m RC and 45,700m diamond drilling programs to ensure resource expansion continues as projected.
