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)

      (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, Form 11-K, Form N-SAR or Form N-CSR, or
            portion thereof will be filed on or before the fifteenth calendar

      (c)   The accountant's statement or other exhibit required by Rule

PART III - NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, N-CSR,
or the transition report or portion thereof, could not be filed within the
prescribed time period.

         As Mitcham Industries, Inc. (the "Company") previously announced,
certain concerns have been raised by an employee about the sufficiency of the
system of internal controls and procedures at the Company's Canadian subsidiary,
Mitcham Canada, that may compromise the integrity of receivables recognized in
the unpublished fourth quarter results of operations. The Company is working
with the audit committee of its board of directors and an independent firm in an
internal investigation of those concerns. The dedication of appropriate Company
resources to assure a thorough investigation and the need to await the findings
of the investigation to consider their impact have delayed the completion of the
financial statements for the fiscal year ended January 31, 2004 and the Form
10-K. Once the investigation is completed, the Company will seek a final review
of the Form 10-K by Hein + Associates LLP, the Company's independent auditors.

      notification.

      Securities Exchange Act of 1934 or Section 30 of the Investment Company
      Act of 1940 during the preceding 12 months or for such shorter period that
      the registrant was required to file such report(s) been filed? If the
      answer is no, identify report(s). [X] Yes [ ] No

(3)   Is it anticipated that any significant change in results of operations
      from the corresponding period for the last fiscal year will be reflected
      by the earnings statement to be included in the subject report or portion
      thereof? [ ] Yes [X] No

      If so, attach an explanation of the anticipated change, both narratively
      and quantitatively, and, if appropriate, state the reasons why a
      reasonable estimate of the results cannot be made.
