Castillian Reports Preliminary Tailings Sampling Returns Average Grade of 1.05 Grams Gold Per Tonne at Hope Brook, Newfoundland

- Additional sampling of tailings has been completed with results pending

TORONTO, ONTARIO -- (Marketwire - March 29, 2012) - Castillian Resources Corp. (TSX VENTURE:CT) ("Castillian" or the "Company") is pleased to announce positive results from preliminary tailings sampling carried out at its Hope Brook Gold Project, southwestern Newfoundland. This initial program designed to provide a general characterization of the tailings consisted of 10 samples taken by a piston corer from six wide spaced locations in the two major tailings ponds as shown in Figure 1. Results are listed in Table 1 below. The overall average grade of the 10 samples is 1.05 g Au/t with a range of 0.41 g Au/t to 1.80 g Au/t. One sample from a small pond south of the main tailings pond also returned 0.98% copper (Cu).

* Sample length is measured from surface of tailings down the vertical piston corer and is not necessarily indicative of the full thickness of the tailings.

Historical production data from the former Hope Brook Mine indicates that approximately 7.9 million tonnes of ore were processed in the mine with 752,163 ounces of gold recovered. Calculated grade of tailings based on the historical production data is 0.54 grams gold per tonne (see NI 43-101 Technical Report to be filed on Sedar). Castillian has completed an additional tailings sampling program at 56 locations as shown on Figure 1. Results from these samples are pending.

Dr. Bill Pearson, Ph.D., P.Geo., President & CEO of Castillian commented, "While preliminary, the results from the tailings sampling returned an average grade double that of the calculated grade based on historical production data suggesting that there may be significantly more gold in the tailings than previously reported. We believe that there is potential to define a significant tailing resource. Additional sampling over both tailings ponds has been completed this winter to better define the overall grade; results are pending. In addition we plan to carry out preliminary bottle roll tests to determine potential recovery."


SAMPLING, ASSAYING AND QUALITY CONTROL

The tailings samples reported in this press release were collected by Fracflow Consultants Inc. using a piston corer. Results pending are for additional tailings samples collected using the same equipment and procedures by Castillian. All samples were prepared and assayed at ALS Chemex, with sample preparation done in Sudbury and analytical work done in Vancouver. All locations of ALS Chemex are ISO 9001:2000 certified. The entire sample received is weighed and crushed to ≥ 70% passing 2mm (10 mesh). A sample split of up to 1000g is then pulverized to ≥ 85% passing 75 microns (200 mesh) to produce a homogenized sample. A 50g aliquot is used for fire assaying with an atomic absorption (AA) finish to determine gold concentration. Copper is initially analyzed using a four acid digestion ICP (inductively coupled plasma-atomic emission spectrometry) method. Any results for copper greater than 10,000 ppm are assayed further by a four acid digestion and "ore grade" ICP method. Internal quality control includes the use of blanks, duplicates and standards in every batch of samples. The Company also conducts internal check assaying using certified external reference standards and blanks. Regular external check assays are performed at a second certified Canadian commercial laboratory. Castillian also inserts external reference standards as well as blank granite drill core in each sample batch as a further external check.


QUALIFIED PERSONS

Mr. Dan Lee, P.Geo., Chief Geologist and Project Manager for Hope Brook, and Dr. Bill Pearson, P.Geo., President and CEO of Castillian, all of whom are qualified persons as defined by NI 43-101, have reviewed and approved the scientific and technical content of this press release. The preliminary tailings sampling program was carried out under the direction of Dr. John Gale, P.Eng., P.Geo. President of Fracflow Consultants Inc. and Glenn Bursey, P.Geo., Vice President/Principal, Senior Hydrogeologist/Geochemist of Fracflow Consultants Inc. Dr. Gale and Mr. Bursey are independent qualified persons as defined by NI 43-101.

Information Concerning Estimates of Indicated and Inferred Resources

This news release uses the terms "indicated resources" and "inferred resources". Castillian advises investors that although these terms are recognized and required by Canadian regulations (under NI 43-101), the U.S. Securities and Exchange Commission does not recognize them. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral reserves. In addition, inferred resources have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for preliminary economic assessments as defined under NI 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
