                                   FORM 12b-25
                           NOTIFICATION OF LATE FILING

For the twelve  months  ended  October 31, 2006,  the Company had a  substantial
increase in general and administrative  expenses,  and therefore a substantially
greater net loss from  operations  compared to the fiscal year ended October 31,
2005.  Since  October  2005,  the  Company  received  funding  from one  private
placement  that  closed in March  2006,  which  provided  the  Company  with the
financial  resources necessary to increase its operations and drilling projects,
and resulting in an increase in exploration-related  expenditures.  As a result,
the  Company's  operations  for the  fiscal  year  ended  October  31,  2006 are
substantially  greater than the year ended October 31, 2005.  This resulted in a
net loss for the twelve  months ended  October 31, 2006 of more than three times
greater than the net loss for the twelve months ended October 31, 2005.
