MineCore's Board of Directors approved the engagement of Whitley Penn as its new Independent Registered Public Accounting Firm as of November 1, 2004. The audit engagement of Whitley Penn is for the periods commencing January 1, 2002 and thereafter. The Company has not consulted with Whitley Penn during the two most recent fiscal years and through October 31, 2004 with respect to 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 consolidated financial statements, or any other matters or reportable events.

With the acquisition of Platinum Works, Inc. and its subsidiaries on June 30, 2004, the scope of the audit requirements for the Company has considerably broadened.

Cardona Rodriguez & Asociados remain engaged by MineCore beyond 2001 with a diminished scope of work related to auditing the Company's operations in Venezuela, consisting mainly of an office in Caracas and exploratory stage gold prospects.

In connection with the audits of the two most recent fiscal years of MineCore for which audits were completed, December 31, 2000 and December 31, 2001, and the subsequent periods through the date hereof, there were no disagreements with MineCore on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Cardona Rodriguez & Asociados' satisfaction, would have caused them to make reference to the subject matter of the disagreements in connection with their reports on MineCore's consolidated financial statements for such periods. Their reports did not contain an adverse opinion nor a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles, except that each such report included an explanatory paragraph describing conditions that raised substantial doubt about MineCore's ability to continue as a going concern.
