ITEM 4.01     Changes in Registrant's Certifying Accountant.

On February 27, 2012, Tresoro Mining Corp. (the "Company") formally informed James Stafford Chartered Accountants of their dismissal as the Company's independent registered principal accountant.

During the Company's two most recent fiscal years preceding the termination of James Stafford Chartered Accountants, and through February 27, 2012, there were no disagreements with James Stafford Chartered Accountants which were not resolved on any matter concerning accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of James Stafford Chartered Accountants, would have caused James Stafford Chartered Accountants to make reference to the subject matter of the disagreements in connection with its report. James Stafford Chartered Accountants, as the Company's principal independent accountant, did not provide an adverse opinion or disclaimer of opinion to the Company's consolidated financial statements, nor modify its opinion as to uncertainty, audit scope or accounting principles, except that the report of James Stafford Chartered Accountants for the fiscal years ended February 28, 2011 and 2010 indicated conditions which raised substantial doubt about the Company's ability to continue as a going concern.

We provided James Stafford Chartered Accountants with a copy of this disclosure before its filing with the Securities and Exchange Commission ("SEC"). We requested that James Stafford Chartered Accountants provide us with a letter addressed to the SEC stating whether or not it agrees with the above statements. A copy of the letter provided by James Stafford Chartered Accountants is filed as Exhibit 16.1 to this Form 8-K.
