Castillian Announces Acquisition of 100% of Maximus Resources Ltd.'s Option/JV Rights to Acquire an Interest in the Las Aguilas Nickel Copper-PGM Property, Argentina From Marifil Mines Ltd.

TORONTO, ONTARIO--(CCNMatthews - March 6, 2007) - David Gower, President & CEO of Castillian Resources Corporation (Castillian) (TSX VENTURE:CT) announces that, subject to regulatory approval, Castillian has reached an agreement with Maximus Resources Ltd. (Maximus) whereby it will acquire 100% of Maximus's rights to acquire an interest (the Underlying Agreement) in the Las Aguillas Nickel-Copper-PGM Project from Marifil Mines Ltd. (Marifil) (TSX VENTURE:MFM). David Gower states: "This is an important acquisition for Castillian as it adds an additional advanced nickel sulfide exploration project within a highly prospective belt-scale property to the company's project portfolio. The property is in an excellent mining jurisdiction with good access which will allow work to proceed efficiently. Advanced nickel sulphide properties such as Las Aguilas are rare in the current market."

The Las Aguilas project is located in San Luis Province, Argentina, 250 km east of Mendoza. It has good infrastructure, being 40 km by paved road from the city of San Luis (population 200,000). Mining is an important contributor to the local economy in San Luis Province. The project covers a large land position which includes the prospective mafic/ultramafic rocks along an 80 km long belt. Previous work has outlined a near-surface resource of 2,200,000 tonnes grading 0.52% nickel, 0.50% copper, 0.04% cobalt, primarily based on drilling between 19701984 by Fabricaciones Militaires (Argentina Government Survey). The resource estimate has not been verified by Castillian and predates the establishment of NI 43-101 standards and as such should not be relied upon by investors. It is provided as information for the purpose of illustrating that a significant quantity of disseminated to semi-massive nickel-copper-PGM rich sulfides are present and represent an excellent exploration target. Previous operators did not analyze for platinum group metals (PGM) and subsequently significant PGM values have been identified in re-analyses of drill core from the resource area. For example quarter core assays show an intercept in hole LA-5-3 of 42 meters grading 0.91 g/t Pt and 0.11 g/t Pd including 3 meters grading 9.1 g/t Pt and 0.45 g/t Pd. Drill hole LA-6-4 intersected 28 meters grading 0.74 g/t PGM.

In order to acquire Maximus's interest Castillian agrees to pay Maximus US$250,000 in cash on signing and issue 200,000 shares of Castillian. The initial cash payment includes reimbursement of funds Maximus has paid to Marifil with respect to obligations in the Underlying Agreement between Maximus and Marifil. In order acquire 100% of Maximus's interest Castillian will also pay Maximus US$100,000 and issue 200,000 shares to Maximus on each of the first and second anniversaries of the agreement.

Castillian agrees to acquire all of Maximus's rights and obligations in the Underlying Agreement with Marifil such that Castillian will have the option to earn up to a 65% interest in the Las Aguilas Project as follows:

1. US$400,000 on or before December 11, 2007;

2. US$600,000 additional on or before December 11, 2008;

3. US$1,000,000 additional on or before December 11, 2009;

4. US$1,000,000 additional on or before December 11, 2010.

2. US$100,000 on or before February 11, 2007 corresponding with the end of the due diligence period (payment already made by Maximus);

3. US$125,000 on or before December 11, 2007;

4. US$125,000 on or before December 11, 2008;

Upon vesting its 50% interest Castillian will have the option to increase its interest to 60% by completing an additional US$2,000,000 in expenditures and delivering a feasibility study.
