EXHIBIT  31.1





CHIEF
EXECUTIVE OFFICER CERTIFICATION





I, K.W.
(“K.D.”) Diepholz, certify that:





1. I have
reviewed this quarterly report on Form 10-Q of DynaResource, Inc.





2. Based
on my knowledge, this quarterly 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 quarterly
report;





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





4. The
registrant’s other certifying officer and I are responsible for establishing and
maintaining disclosure controls and procedures (as defined in Exchange Act Rules
13a-14 and 15d-14) for the registrant and we 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
registrant, including its consolidated subsidiaries, is made known to us 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 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





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





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





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





a) all significant deficiencies and
material weaknesses in the design or operation of internal controls over
financial reporting which are reasonably likely to adversely affect the
registrant’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
registrant’s internal control over financial reporting.
