Castillian Intersects 2.14 g Au/t and 0.45% Cu Over 29.6 Metres at Hope Brook, Newfoundland

TORONTO, ONTARIO--(Marketwire - Dec. 11, 2012) - Castillian Resources Corp. (TSX VENTURE:CT)(OTCQX:CTIIF) ("Castillian" or the "Company") has completed 3,833 meters of drilling in 12 holes at four of the six major target areas of the 6,000 metre diamond drilling program at its Hope Brook Gold Project in southwestern Newfoundland.

Highlights from recent drilling include:

Unmined Stope Potential

• Hole HB 12-091: 2.14 grams gold per tonne (g Au/t) and 0.45% copper (Cu) over 29.6m core length; including 5.24 g Au/t and 1.47% Cu over 4.3m core length
  
  
  
  
• Hole HB12-094: 1.90 g Au/t and 0.12% Cu over 39.1m core length; including 3.95 g Au/t over 12.50m core length
  
  
  
  

Mine Zone to 240 Connector Target

• Hole HB 12-093: 0.64 g Au/t over 16.5m core length; including 1.66 g Au/t over 2.40m core length
  
  
  
  
• Hole HB 12-092: 0.52 g Au/t over 10.6m core length within a 22.5 metre wide mineralized silicified zone.
  
  
  
  

Drilling has progressed rapidly with four rigs now operating along a 3.4-kilometre long mineralized trend between the past-producing Hope Brook Mine southwest to the Chetwynd South Prospect (see press release dated November 5, 2012). All twelve drill holes completed to date have intersected the silicified mineralized zones as targeted from our geological and geophysical data. Currently holes are in progress on the Chetwynd, Connector Zone and NW target areas. Figure 1 shows the locations of the target areas and drill hole pierce points. Table 1 lists significant assay results. Assays have been received for the first four drill holes completed (HB12-091 to -094).

Dr. Bill Pearson, P.Geo., President and CEO of Castillian, commented: "We are on schedule to complete the planned 6,000m drill program before Christmas. This program is designed to open up major new target areas for future resource definition. I am very encouraged by the results to date. We have confirmed that the major silicified mineralized zones extend for at least 3.4km along strike and are open along strike and downdip. Drilling in progress is focussing on identifying areas with higher grade gold within these extensive alteration zones particularly in the Connector zone."

Unmined Stope Potential (4960-150 level Stope)

Two drill holes tested the potential for unmined ore remaining in the 4960-150 stope at the south west end of the former Hope Brook Mine. Hole HB12-091 and Hole HB12-094 (which was positioned to test the eastern end of the stope) intersected pyrite- and chalcopyrite-bearing, vuggy, buff and grey siliceous alteration over 76.4m and 54.1m respectively. This drilling confirms that the 4960-level stope was only partially blasted and remains in place, and is expected to add to the current mineral resource.

Hole HB12-091 intersected an altered zone containing chalcopyrite that graded 2.14 g Au/t and 0.45% Cu over 29.6m (13.4m true width) including 5.24 g Au/t and 1.47% Cu over 4.3m (2.0m true width). No zones of excessive broken core or zones of lost core were encountered during drilling suggesting that this portion of the former stope remains intact.

Hole HB12-094, a zone of chalcopyrite (1-2%) and bornite-bearing siliceous altered material assayed 1.90 g Au/t and 0.12% Cu over 39.10m (16.5m true width) including 3.95 g Au/t and 0.07% Cu over 12.50m (5.3m true width). The drill hole intersected small void spaces and blocky, locally oxidized rock, with approximately 20% lost core between 180.9m and 220.0m. The recovered core shows no sign of displacement or rotation hence this portion of the stope was likely fractured, but not blasted and mined.

Mine Zone to 240 Connector Target

The initial two drill holes, HB12-092 and 093 confirmed the continuity of the gold mineralized zone within the northern part of the Mine Zone to 240 Connector Target. These holes both intersected the mineralized zone approximately 200m southwest of the resource constraining shell (cutoff grade of 0.5 g Au/t) that outlines the current limit of potential open pittable resource at Hope Brook (Figure 1).

Hole HB12-092 encountered a zone of pyrite-bearing siliceous altered rocks from 314.4 to 330.9m that assayed 0.64 g Au/t over 16.5m core length (12.6m true thickness). Drill hole HB12-093 intersected a 22.5 metre core length of pyrite and chalcopyrite-bearing, locally vuggy, grey and buff siliceous altered rocks from 358.5 to 381.0m which included 0.52 g Au/t over 10.6m core length (7.0m true width). Geophysical data indicates that the intensity of alteration and mineralization likely increases further southwest to the 240 Zone-this area is currently being drill tested.

SAMPLING, ASSAYING AND QUALITY CONTROL

The core (NQ (47.6 mm) and BQTK (40.54 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 Minerals, with sample preparation done in Sudbury and analytical work done in North Vancouver. All locations of ALS Minerals 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.
