                      CERTIFICATION OF PRINCIPAL EXECUTIVE
                                     OFFICER

Pursuant to Section 302 of the Sarbanes-Oxley Act of 2002

I, MICHAEL CYTRYNBAUM, certify that:

      1.   I have reviewed the annual report on Form 20-F of CENTRAL MINERA
           CORP.

      2.   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;

      3.   Based on my knowledge, the financial statements, and other financial
           information included in this report, fairly present in all material
           respect the financial condition, results of operations and cash flows
           of the company as of, and for, the periods presented in this report.

      4.   The Company's other certifying officer and I are responsible for
           establishing and maintaining disclosure controls and procedures (as
           defined in Exchange Act Rules 13A-15(e) and 15d-15(e)) for the
           Company and have:

           (a)  Designed such disclosure controls and procedures, or caused such
                disclosure controls and procedures to be designed under or
                supervision, to ensure that material information relating to the
                Company, 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)  Disclosed in this report any change in the Company's internal
                control over financial reporting that occurred during the period
                covered by the annual report that has materially affected, or is
                reasonably likely to materially affect, the Company's internal
                control over financial report; and

      5.   The Company's other certifying officer and I have disclosed, based on
           our most recent evaluation of internal control over financial
           reporting, to the Company's auditors and the audit committee of the
           Company's board of directors:

           (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 Company'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 Company's
                internal control over financial reporting.

Dated this 25th day of November, 2003.
