CALGARY, ALBERTA--(Marketwired - June 5, 2013) - Celeste Mining Corp. (TSX VENTURE:C) ("Celeste" or the "Company") announces today that the Company has been issued a formal notice of default on behalf of Cornish Minerals Limited ("CML") with respect to its failure to fulfill its obligations under the Earn In Agreement dated May 24, 2011 (as amended from time to time) ("EIA"). In addition, the Company announces that Mr. Alan Shoesmith has resigned from the Company's Board of Directors.

As a result of deteriorating equity markets, the financial position of the Company, operational complexities and higher than anticipated exploration and development expenses at the South Crofty Mine the Company has been engaged in a review of cost cutting measures (reference press release May 29, 2013). As a result of such review the Company determined not to contribute further expenditures to the South Crofty Mine. In response, the Company has been issued a Notice of Default on behalf of CML which could, among other things, result in dilution to its interest in the South Crofty Mine.

Management continues to actively engage strategic partners in an effort to explore alternative funding strategies, which may include a brokered convertible financing in order to finance the expenditures at the South Crofty Mine provided that the Company and its joint venture partners at the South Crofty Mine can agree on appropriate cost cutting measures and a suitable budget and plan.
