TORONTO, ONTARIO--(Marketwire - June 6, 2011) - Castillian Resources Corp. ("Castillian" or the "Company") (News - Market indicators) is pleased to report results from an additional seven diamond drill holes that tested the downdip and along strike extension of the Pit Zone, a near surface gold mineralized zone immediately southwest of the former open pit mine at its Hope Brook gold property. Previous drilling confirmed that the Pit Zone extends at least 500 metres along strike (See Press Release dated April 5, 2011). This new drilling confirms gold mineralization to a depth of 100 metres. 

Significant results are given in Table 1 below. Highlights are as follows:

• 1.26 g Au/t and 0.10% Cu over 18.6m core length (14.0m true width) from 38.7m to 57.3m including 2.59g Au/t and 0.27%Cu over 6.1m core length (4.6m true width) in hole HB-11-018;

• 1.03 g Au/t over 31.5m core length (23.6m true width) from 90.3m to 121.8m including 2.49 g Au/t over 8.4m core length (6.3m true width) in hole HB11-024; and

• 1.60 g Au/t and 0.15%Cu over 16.9m core length (12.7m true width) from 118.0m to 134.9m including 3.48g Au/t and 0.37%Cu over 6.2m core length (4.7m true width) in hole HB11-029

"We are continuing to receive positive drill results from the Pit Zone. A number of the holes have multiple zones of gold mineralization and several have significant copper mineralization. Drilling with the track drill is continuing to test the Pit Zone further along strike and downdip," Dr. Bill Pearson, P.Geo., President & CEO of Castillian, commented. "With improved weather conditions, we have also resumed surface and bore hole induced polarization surveys which are very effective at outlining the favourable silicified zones. In addition, we are continuing to upgrade and improve our geological interpretation of the mineralized zones to better predict both extensions to known zones and to define new targets."

To date 25 diamond drill holes totaling 4,166 metres have been completed across the 500m strike length of the Pit Zone, as shown in Figures 1 and 2, vertical longitudinal sections. Figure 3 shows the collar locations of the drill holes on an aerial photograph of the open pit area. All holes have intersected significant gold values with several holes also having copper mineralization. A number of holes also have multiple zones of gold mineralization as shown in Table 1. Interpretation of airborne and ground geophysical data indicates that the silicified zone hosting the gold mineralization extends at least another 800m further along strike to the southwest. Responses for both resistivity indicating silicification and chargeability indicating the presence of sulphides along this additional potential extension are very comparable to responses across the 500m long section already drilled. Drilling is continuing to test the Pit Zone further along strike and downdip.

Four additional holes have been completed to further test the Hanging Wall and Main Zones as shown in Figure 1, set out below. Results for these holes are pending. Since the start of drilling in September 2010, a total of 36 holes totaling 10,267 metres have been completed at Hope Brook on all target zones, with a further 15,000m planned for the balance of 2011 to bring the overall planned drilling to 25,000m.

SAMPLING, ASSAYING AND QUALITY CONTROL

The core (NQ 47.6 mm and BTW 42.0 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 ≥ 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. 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.
