NEWS Castillian Intersects 3.78 g Au/t Over 53 Metres in Footwall Zone Within Former Mine at Hope Brook
TORONTO, ONTARIO--(Marketwire - June 25, 2012) - Castillian Resources Corp. ("Castillian" or the "Company") (TSX VENTURE:CT)(OTCQX:CTIIF) is pleased to report the final results from its 4,316 metre diamond drilling program in 15 holes, which completes the first phase of drilling in the Company's 2012 exploration program at the Hope Brook Gold Project, located in southwestern Newfoundland. These last holes reported in this news release focused on confirming the locations of workings and major pillars in the deeper part of the Mine Zone area (HB12-080E, -087) and further testing the Southwest Extension target area (HB12-089, -090) (see also the press release dated June 5, 2012 for a discussion of the previous results released). Significant results are summarized in Table 1 below. Highlights are as follows:
Mine Zone Area
- Hole HB12-087, drilled from northwest to southeast, intersected 3.78 grams of gold per tonne ("g Au/t") over 53.0 metres core length (16.9 metres true width) from 271.0 to 324.3 metres and a second zone grading 4.41 g Au/t over 5.0m (1.6 metres true width) from 354.5 metres to 359.5 metres in the footwall area below the old workings.
- Hole HB12-080E, an extension of previously reported hole HB12-080 which was lost, intersected 2.14 g Au/t over 14.4 metres core length (10.8 metres true width) in a shallow pillar within the former mine at approximately the 5000 metre level (122 metres below surface).
Southwest Extension Area
- 1.21 g Au/t over 23.1 metres core length in hole HB12-090. This hole is approximately 500 metres southwest of the former open pit.
- 0.78 g Au/t over 11.7 metres core length including 1.13 g Au/t over 5.7 metres core length in hole HB12-089.
Dr. Bill Pearson, P.Geo., President & CEO of Castillian, commented: "These new results continue to confirm that significant pillars remain in the former mine and that there is potential for a significant remaining footwall mineralized zone. The southwest extension remains open along strike and downdip with good potential to define additional mineral resources in this area and potentially extend the constraining shell defining the mineral resource estimate further to the southwest. Work is continuing on the geological mapping and prospecting program over the full 8 kilometre strike length of the favourable mineralized structure as well as compilation of historical data."
Figure 1 shows the location of the major target areas with pierce points of the 2012 holes in the Southwest Extension Target and Northeast Target areas. Figure 2 is a longitudinal section of the Mine Zone area showing the historical workings and the locations of pierce holes in the former mine area completed in this program and in the 2011 drilling program. Collectively, these holes provide good overall coverage with holes drilled from both the north and south of the mine to provide maximum coverage. Table 2 lists collar coordinates, dip, azimuth and length for all holes drilled in the 2012 program.

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 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.
