Item 4.01 Changes in Registrant’s Certifying Accountant

Effective June 25, 2012, Mattmar Minerals, Inc.. (the “Company”) dismissed De Joya Griffith & Company, LLC., (“DeJoya”) from serving as the Company’s independent accountants. As of June 25, 2012 the Company engaged Sherb & Co., LLP (“Sherb”) as its new independent accountants. The Company’s Board of Directors unanimously recommended that the Company change audit firms, directed the process of review of candidate firms to replace DeJoya and made the final decision to engage Sherb.

The reports of DeJoya on the financial statements of the Company for the years ended May 31, 2010 and 2011 contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle. In connection with its audits of the years ended May 31, 2010 and 2011 and reviews of the Company’s financial statements through June 25, 2012, there were no disagreements with DeJoya on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of DeJoya, would have caused them to make reference thereto in their report on the financial statements for such years.

The Company has furnished to DeJoya the statements made in this Item 4.01. Attached as Exhibit 16.1 to this Form 8-K is DeJoya’s letter to the Commission, dated June 25, 2012 regarding these statements.

During the two most recent fiscal years and through June 25, 2012, the Company has not consulted with Sherb on any matter that (i) involved the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, in each case where a written report was provided or oral advice was provided that Sherb concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) was either the subject of a disagreement, as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K, or a reportable event, as that term is defined in Item 304(a)(1)(v) of Regulation S-K.
