New Hanging Wall Drill Holes Intersecting Higher Gold Grades than Historic Drill Holes

Mar. 23, 2011 (Marketwire) --

.

TORONTO, ONTARIO -- (Marketwire) -- 03/23/11 -- Castillian Resources Corporation ("Castillian" or the "Company") (TSX VENTURE:CT) is pleased to report results from two (2) additional drill holes at its Hope Brook Gold Project located on the southwest coast of Newfoundland. Significant drill results are detailed in Table 1 below. Highlights include:

"HANGING WALL ZONE" - Approximately 30-50m into the hanging wall, above previously mined Mine Zone

--  3.12 g Au/t over 9.0m core length (6.8m true width) from 152.9 to 161.9m
    including 9.26 g Au/t over 2.0m (1.5m true width) and 2.37 g Au/t over
    18.30m from 175.0 to 193.90 including 4.56 g Au/t over 8.9m (6.7m true
    width) in Hole HB11-011. These intersections are approximately 130m
    below surface.  
--  Hole HB-11-012 intersected 2.39 g Au/t and 0.16 %Cu over 19.30m (14.5m
    true width) including 6.63 g Au/t and 0.46% Cu over 3.7m core length
    (2.8m true width) on the same section as Hole HB11-011 approximately
    120m further below the intersection in Hole HB11-011.  
--  Hole HB11-011 was a re-drill of historic hole CW-64 which intersected
    3.34 g Au/t over 2.0m core length, 6.32 g Au/t over 3.4 m core length
    and 3.83 g Au/t over 6.4m core length.  
--  The intersections in hole HB11-011 were higher grade and more extensive
    than those reported in the historic drill hole. 

"MINE ZONE" - Extension of the Main Mineralized Zone mined from the previous Underground Operation

--  5.92 g Au/t over 2.5m core length (1.9m true width) from 358.5 to 361.0m
    and 1.65 g Au/t over 16.5m core length (12.4m true width) including 2.62
    g Au/t over 3.0m core length (2.3m true width) in Hole HB11-012.  
--  This hole, which intersected the Hanging Wall Zone as noted above, was
    expected to intersect the underground workings however the hole passed
    through an unmined part of the deposit and tested the full downdip
    extent of the Mine Zone approximately 50m below the 4800m level, the
    deepest level that was developed in the mine at approximately 340m below
    surface.  

Dr. Bill Pearson, P.Geo., President & CEO of Castillian, commented: "We continue to be very pleased with the positive drilling results on the Hanging Wall and Mine Zones. The Hanging Wall Zone now extends at least 300m vertically and is open downdip and along strike to the southwest. Hole HB 11-012 further confirmed the downdip continuity of the Mine Zone below the 4,800m level, the lowest level previously mined. We are using a drill hole pattern that is designed to optimize potential resource definition as well as evaluate further extensions of both target zones.

SAMPLING, ASSAYING AND QUALITY CONTROL

The core (NQ 47.6 mm) is logged, photographed and then sawn in half with one-half sent to the laboratory for analysis and the other half retained and stored on site. All core samples were prepared and assayed at ALS Chemex with sample preparation done in Sudbury and analytical work in Vancouver. All locations of ALS Chemex are ISO 9001:2000 certified. The entire sample received is weighed and crushed to greater than or equal to 70% passing 2mm (10 mesh); a sample split of up to 1000g is then pulverized to greater than or equal 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. 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.

Mr. Dan Lee, P.Geo. Chief Geologist and Project Manager for Hope Brook and Dr. Bill Pearson, P.Geo., President and CEO of Castillian, both of whom are qualified persons as defined by National Instrument 43-101 ("NI 43-101"), have reviewed and approved the scientific and technical content of this press release.
