                  SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002


In connection with the accompanying Quarterly Report on Form 10-QSB of Big Cat
Mining Corporation for the quarter ending July 31, 2005, as filed with the
Securities and Exchange Commission on the date hereof, the undersigned, in the
capacity and date indicated below, hereby certifies that:

I have reviewed this quarterly report on Form 10-QSB of Big Cat Mining
Corporation;

Based on my knowledge, this report does not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
made, in light of the circumstances under which such statements were made, not
misleading with respect to the period covered by this report;

Based on my knowledge, the financial statements, and other financial information
included in this report, fairly present in all material respects the financial
condition, results of operations and cash flows of the small business issuer as
of, and for, the periods presented in this report;

The small business issuer's other certifying officer(s) and I are responsible
for establishing and maintaining disclosure controls and procedures (as defined
in Exchange Act Rules 13a-15(e) and 15d-15(d)) and internal control over
financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f))
for the small business issuer and have:

     (a)  designed such disclosure controls and procedures, or caused such
          disclosure controls and procedures to be designed under our
          supervision, to ensure that material information relating to the small
          business issuer, including its consolidated subsidiaries, is made
          known to us by others within those entities, particularly during the
          period in which this report is being prepared;

     (b)  designed such internal control over financial reporting, or caused
          such internal control over financial reporting to be designed under
          our supervision, to provide reasonable assurance regarding the
          reliability of financial reporting and the preparation of financial
          statements for external purposes in accordance with generally accepted
          accounting principles;

     (c)  evaluated the effectiveness of the small business issuer's disclosure
          controls and procedures and presented in this report our conclusions
          about the effectiveness of the disclosure controls and procedures, as
          of the end of the period covered by this report based on such
          evaluation; and

<PAGE>

     (d)  disclosed in this report any change in the small business issuer's
          internal control over financial reporting that occurred during the
          small business issuer's most recent fiscal quarter (the small business
          issuer's fourth fiscal quarter in the case of an annual report) that
          has materially affected, or is reasonably likely to materially affect,
          the small business issuer's internal control over financial reporting;
          and

The small business issuer's other certifying officer(s) and I have disclosed,
based on our most recent evaluation of internal control over financial
reporting, to the small business issuer's auditors and the audit committee of
the small business issuer's board of directors (or persons performing the
equivalent functions):

     (a)  all significant deficiencies and material weaknesses in the design or
          operation of internal control over financial reporting which are
          reasonably likely to adversely affect the small business issuer's
          ability to record, process, summarize and report financial
          information; and

     (b)  any fraud, whether or not material, that involves management or other
          employees who have a significant role in the small business issuer's
          internal control over financial reporting.
