Castillian Appoints Helio B. Diniz as Chief Operating Officer, Provides Update on Drilling at Mangabal Project, Brazil

David Gower, President & CEO of Castillian Resources Corporation (TSX VENTURE: CT) is pleased to welcome Helio B. Diniz as Chief Operating Officer of Castillian and Managing Director of Castillian Metais Ltda. (Castillian's Brazilian Subsidiary). Mr. Diniz has an exceptional track record of discovery which spans a 26 year career in Brazil and South Africa and has demonstrated the ability to assemble strong technical teams and execute large projects efficiently in Brazil. David Gower, President & CEO of the Company stated: "Helio Diniz's successful track record in Brazil and insights into the Brazilian mining and exploration industry will be a key competitive advantage as the Company expands its efforts in Brazil."

Mr. Diniz was most recently the Director of Exploration, Brazil for Falconbridge and Noranda (now Xstrata) where he was a primary discoverer of the Araguaia Nickel Deposits which are currently the subject of scoping studies by Xstrata. He and his team also assembled one of the most impressive IOCG property portfolios in the renowned and prolific Carajas Mineral District and successfully acquired nickel sulfide and copper properties elsewhere in the country, including the large Mangabal Project land position that is presently a core focus for Castillian.

Prior to joining Noranda, Mr. Diniz worked with Gencor (South African Group) where a key accomplishment was the evaluation and subsequent development of the Sao Bento Gold Mine in Brazil, which ultimately operated for 25 years. During the 19 years with Gencor and later Eldorado Gold Mr. Diniz managed numerous multi-million dollar gold and PGM exploration programs throughout Brazil.

Mr. Diniz will be based at the newly established Castillian Matais Ltda. office in Belo Horizonte, Brazil.

A diamond drill is on site and setting up on the Metago Zone, at the Mangabal nickel sulfide project in Brazil (see press release dated 14/02/07 for details). The initial 3000 meter drill program is designed to delineate the extent of the Metago Zone and provide sufficient drilling to calculate a resource that is suitable for completing a scoping level evaluation of the deposit. The drill will then move to evaluate six additional high priority targets within Mangabal Intrusion which hosts the Metago Zone.
