In connection with the Quarterly Report of Mountains West Exploration,            Inc. (the “Company”) on Form 10-QSB for the period ended June 30, 2007 as            filed with the Securities and Exchange Commission on the date hereof (the            “Report”), I, Lee Wiskowski, President and principal executive officer of            the Company, certify, pursuant to 18 USC section 1350, as adopted pursuant to Section            906 of the Sarbanes-Oxley Act of 2002, that to the best of my knowledge and            belief:

 

|   | (1) | I have reviewed this quarterly report on Form 10-QSB of                            Mountain West Exploration, Inc.; |
|--------|-----|---------------------------------------------------------------------------------------------------------------------|

             

(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 the 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 the report;

             

(4)        The small business            issuer’s other certifying officer and I are responsible for establishing and            maintaining disclosure controls and procedures (defined in Exchange Act Rules 13a-15(e)            and 15(d)-15(e)) for the small business issuer and have:

             

i.         Designed such            disclosure controls and procedures to ensure that material information relating to the            small business issuer, including its consolidated subsidiaries, is made know to us by            others within those entities, particularly during the period in which the periodic            reports are being prepared;

 

ii.         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

 

iii.        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

 

(5)        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):

 

i.          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            small business issuer’s ability to record, process, summarize and report            financial information; and

             

ii.         Any fraud,            whether or not material, that involves management or other employees who have a            significant role in the small business issuer’s internal controls; and

             

(6)        I and the other            certifying officer have indicated in the report whether or not there were significant            changes in internal controls or in other factors that could significantly affect            internal controls subsequent to the date of their most recent evaluation, including any            corrective actions with regard to significant deficiencies and material            weaknesses.
