                           CERTIFICATION PURSUANT TO
                 SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I,  Alfonso  Quijada,  the  President,  Chief Executive Officer, Chief Financial
Officer  and  Principal  Accounting  Officer  of Castmor Resources Ltd., certify
that:

1.     I  have  reviewed this quarterly report on Form 10-Q of Castmor Resources
Ltd.;

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 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;

4.     I am responsible for establishing and maintaining disclosure controls and
procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the
registrant and I have:

     a)   designed  such  disclosure  controls  and  procedures  to  ensure that
          material  information  relating  to  the  registrant,  including  its
          consolidated  subsidiaries, is made known to me by others within those
          entities,  particularly  during  the  period  in  which this quarterly
          report  is  being  prepared;

     b)   evaluated  the  effectiveness  of the registrant's disclosure controls
          and procedures as of a date within 90 days prior to the filing date of
          this  quarterly  report  (the  "Evaluation  Date");  and

     c)   presented  in  this  quarterly  report  our  conclusions  about  the
          effectiveness  of  the  disclosure controls and procedures based on my
          evaluation  as  of  the  Evaluation  Date;

5.     I have disclosed, based on our most recent evaluation, to the
registrant's auditors and the audit committee of registrant's board of directors
(or persons performing the equivalent function):

     a)   all  significant  deficiencies  in the design or operation of internal
          controls  which  could  adversely  affect  the registrant's ability to
          record,  process,  summarize  and  report  financial  data  and  have
          identified  for  the  registrant's auditors any material weaknesses in
          internal  controls;  and

     b)   any  fraud, whether or not material, that involves management or other
          employees  who  have  a  significant role in the registrant's internal
          controls.

6.     I have indicated in this quarterly report whether there were significant
changes in internal controls or in other factors that could significantly affect
internal controls subsequent to the date of my most recent evaluation, including
any corrective actions with regard to significant deficiencies and material
weaknesses.
