EXHIBIT 31.2





CHIEF FINANCIAL
OFFICER CERTIFICATION





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





I have reviewed this report on Form 10-Q of DYNARESOURCE,
INC.;





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 registrant as of, and for, the
periods presented in this 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-15 (e) and
15d-15(e) and internal controls over financial reporting (as
defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the
registrant 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
registrant, 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 controls over financial reporting, or caused
such internal controls 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 registrant’s disclosure
controls and procedures and presented in this report our conclusion
about the effectiveness of the disclosure controls and procedures,
as of the end of the period covered by this report based on such
evaluation;





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


The registrant’s other certifying officer and I have
disclosed, based on our most recent evaluation of internal controls
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 controls over financial
reporting.
