CASABLANCA MINING LTD. (OTCQB:CUAU) announced today that the agreement with Angelique de Maison in which she agreed to invest in the Company through the purchase of common stock, was completed on December 31, 2011, the expiration date of the agreement. Ms. de Maison invested a total of $4.8 million under this agreement through December 31, 2011. Ms. de Maison has invested a total of $6.7 million in the Company directly and indirectly since December of 2010 and has loaned the Company an additional $900,000.

The Company is currently negotiating with Ms. de Maison for an additional investment in 2012.

Juan Carlos Camus, CEO of Casablanca Mining and its Chilean subsidiary, Santa Teresa Minerals, said, "We are very thankful to Ms. de Maison for her investments to date which have been critical to Casablanca's continued growth. We are pleased that she plans to continue her support in 2012."

Ms. de Maison said, "I continue to be impressed by the opportunities in Casablanca Mining and Santa Teresa Minerals and look forward to furthering my investment. Copper sulfate remains in high demand in both agricultural and industrial markets and gold was one of 2011's best performing assets. I am excited about the demand for gold in 2012 as governments continue to increase debt at an alarming rate which, in my opinion, bodes very well for gold and gold companies."
