From the Cautionary Notes:

Known risk factors include:

• Schaft Creek Joint Venture may not result in a Production Decision being made, or the construction of a mine
• Further exploration and development of the Schaft Creek property may not occur as expected
• Cash payments to Copper Fox may not be paid by Teck in the quantum or timing expected, or at all
• Financing commitments may not be sufficient to advance the Schaft Creek project as expected, or at all
• Proven and probable reserves at Schaft Creek may not be in the quantum as currently expected, or result in economic mining thereof
• The possibility that future obligations with respect to the Sombrero Butte property may not be met on a timely basis, or at all
• Planned activities for the Van Dyke and Sombrero Butte properties many not commence as currently planned, or at all
• A current (43-101 compliant) resource estimate, and a Preliminary Economic Assessment may never be obtained by the Company for the Van Dyke property
• The need to obtain additional financing and uncertainty as to the availability and terms of future financing
• The possibility of delay in exploration or development programs; and uncertainty of meeting anticipated program milestones.

The August NR also talked about possibly not being able to connect to the NTL.

These seem pretty specific, but doesn't nessasarily mean there is a real risk. Make your own intreprtations. Why add this now though? These have been issues for more than a year.

They definately have their collective butt covered.
