Castillian Starts 6,750 line Km Helicopter-VTEM Magnetic and Electromagnetic Survey on the Kagera Project, Tanzania Including Property Directly Northeast of the Kabanga Nickel Sulfide Deposits

TORONTO, ONTARIO--(Marketwire - March 26, 2008) - Castillian Resources Corporation (TSX VENTURE:CT) announces the start of a 6,750 line kilometre VTEM airborne magnetic and electromagnetic (EM) survey on its 100% owned Kagera Project in Tanzania (Figure 1). The survey is being flown by Geotech Airborne Limited of South Africa employing the B-field Versatile Time-Domain Electromagnetic (VTEM) system. A total of 6,750 line kilometres of magnetic and electromagnetic (EM) data will be collected on survey lines spaced 200 metres apart over a 1,075 square kilometre area.

The planned survey will cover the property directly north of the Kabanga Nickel sulfide deposits owned by Barrick and X-strata Nickel (Figure 2). Based on a September, 2006 presentation to analysts by Xstrata the Kabanga deposits contained resources in all categories in excess of 45 Million tonnes grading more than 2.5% Ni at that time. The Kabanga project is currently the focus of an ongoing feasibility study by Xstrata Nickel and Barrick. The resource comprising the Kabanga depsosits ranks among the worlds largest undeveloped nickel sulfide deposits. Castillian has a 100% interest in the Kagera Project in Western Tanzania which comprises seven large claims totalling 1357.8 square km. The key claims are approximately 6 km directly along the regional geological and geophysical trend northeast of the Kabanga Nickel deposits. There are also two known nickel sulphide occurrences within the Luhuma trend (Figure 2) to the north and east of Castillian's Kagera property such that the land position is well placed within the mineralized trend.

Recent remote mapping using satellite images and geophysical data and field mapping by Castillian confirm that a 20 km long belt of prospective mafic and ultramafic rocks occur on the Castillian Property immediately on trend with the Kabanga deposits.

Joel Hrominchuk, P.Geo., Exploration Manager of the Project stated, "This survey is a very important step in the exploration of the Kagera property as it will accurately outline the areas underlain by the prospective ultramafic-mafic rocks trending onto Castillian's claims and provide high resolution EM and Mag coverage over the most important claims particularly directly on strike from known mineralization on adjacent properties both north and south of Castillian's property. Castillian intends to promptly follow up the survey with ground EM, soil geochemistry and ultimately drilling during 2008." The survey is expected to be completed with preliminary interpretations available by late April.

Quality Control

The data collected from the airborne survey will be monitored during collection and subsequently processed by Dr. Mark Shore, P. Geo. A qualified person as defined by National Instrument 43-101. Dr. Shore is an independent consulting geophysicist who provides services to the company under the direction of Castillian Exploration Manager, Joel Hrominchuk, P.Geo., Mr. Hrominchuk has reviewed the scientific and technical information in this press release. Mr Hrominchuk is a qualified person as defined by National Instrument 43-101.
