CASABLANCA MINING (OTCQB: CUAU) announced today that its subsidiary, Santa Teresa Minerals SA, had entered into an agreement to sell its 60% interest in Sulfatos Chile SA to Bluestone Minerals SA. The purchase price will be cash in the amount of $2.2 million, payable $1 million at closing and the balance in monthly installments as demanded by Santa Teresa, and an equity interest in Bluestone that represents 20% of the outstanding stock of Bluestone after the transaction. Bluestone was recently formed by Juan Carlos Camus Villegas, Chief Executive Officer, Chairman of the Board, and a shareholder of Casablanca, and Angelique de Maison, a director and shareholder of Casablanca, to acquire the interest in Sulfatos Chile. The transaction will close upon completion of the "escritura" process as proscribed by Chilean law.

"This is a very beneficial transaction for our company as it allows us to streamline our operations and focus our efforts and finances on our core business, our gold projects. We will use the cash to continue to fund our Free Gold project and accelerate the exploration efforts at our New Gold project," said Casablanca Mining President Zirk Engelbrecht. "In addition, we have been able to retain a substantial minority equity interest in Sulfatos Chile through our interest in Bluestone Minerals."
