PART II - RULES 12b-25(b) AND (c)

If  the  subject  report  could not be filed without unreasonable  effort  or
expense  and  the  registrant seeks relief pursuant to  Rule  12b-25(b),  the
following should be completed.  (Check box if appropriate)  [X ]

[X] (a)  The reasons described in reasonable detail in Part III of this  form
    could not be eliminated without unreasonable effort or expense;

[X] (b)  The subject annual report, semi-annual report, transition report  on
    Form  10-K,  Form  20-F, 11-K or Form N-SAR, or portion thereof  will  be
    filed  on  or before the fifteenth calendar day following the  prescribed
    due date; or the subject quarterly report or transition report on Form 10-
    Q,  or portion thereof will be filed on or before the fifth calendar  day
    following the prescribed due date; and

[ ] (c)  The  accountant's statement or other exhibit required by  Rule  12b-
    25(c) has been attached if applicable.

PART III - NARRATIVE

State  below in reasonable detail the reasons why Form 10-K and Form  10-KSB,
20-F,  11-K, 10-Q and Form 10-QSB, N-SAR, or the transition report or portion
thereof could not be filed within the prescribed period.

The registrant is unable to file timely its report of Form 10-QSB without
unreasonable effort and expense because certain joint billing information
that is required for the preparation of the financial information required to
be included in such report was provided to the registrant at too late a date
to incorporate such information in the registrant' financials.  This joint
billing information relates the registrant's joint venture in the Greater
Trona area of Wyoming, where it has focused its oil and gas exploration
activities to date, and was provided by the registrant's co-party in this
joint venture.
