Castillian Resources Corporation (TSX VENTURE:CT) has reported results from two additional drill holes and announce the re-commencement of drilling at its Hope Brook Gold Project located on the southwest coast of Newfoundland.
"PIT ZONE" - Near Surface Gold Zone Southwest of former Open Pit Mine
- 1.44 g Au/t over 28.0 m core length (21.1 m true width) from 61.90 m to 89.90 m including 3.56 g Au/t over 5.9 m core length (4.5 m true width) in Hole HB10-009 approximately 270m southwest of the open pit. This hole is on section and about 40 m below the intersection of 2.08 g Au/t over 15.3 m core length (11.6 m true width) in Hole HB10-004 previously reported (see press release December 1, 2010) confirming the downdip extent of the gold mineralized zone. The Pit Zone has a minimum strike extent of 500 m. A track mounted diamond drill is being mobilized to the project to accelerate the delineation of this zone to provide data for a NI 43-101 resource estimate later in 2011.
"MINE ZONE" – Extension of the Main Mineralized Zone mined from the previous Underground Operation
- 3.17 grams gold per tonne (g Au/t) and 0.91% copper (Cu) over 9.90 metres (m) (6.0 m true width) within a broad zone of mineralization grading 1.08 g Au/t and 0.22 % Cu over 69.10 m core length (41.6 m true width) in Hole HB10-008. This hole intersected the main mineralized zone approximately 50 m southwest of the 4800 level in the former Hope Brook mine which is about 340 metres below surface and confirms that the main zone mined underground continues southwest of the old workings.
Dr. Bill Pearson, P.Geo., President & CEO of Castillian commented: "We are very pleased with the results of our initial drill program at Hope Brook. These results confirm the excellent potential of our major target areas both near surface and for extensions of the zone previously mined from underground. The Hope Brook Mine closed during a period of very low gold prices, well before the deposit was completely mined out. We believe we are in a fortunate situation where we can extend the known mineralization from the unmined parts of the Hope Brook deposit and build toward a NI 43-101 resource estimate later this year. Significantly, many of the deeper historic drill holes appear to have been too short to fully test the target zone. In view of these results, Castillian will be expanding the drill program by an additional 10,000 metres and will be adding a second mobile drill to delineate the near surface target zone which to date extends more than 500 metres southwest of the past producing open pit. The drill, currently on site, will focus on expanding the Hope Brook Deposit Mine Zone southwest and below the mine workings, as well as further testing the new hanging wall zone."
To date a total of 3,731 m in ten (10) drill holes have been completed of which seven (7) holes have been previously reported (see press releases November 17, 2010 and December 1, 2010). Assays for Hole HB10-010 are pending.
Hole HB10-008 intersected a wide zone of silicification grading 1.08 g Au/t and 0.22% Cu over 69.10 m core length (41.6 m true width) including a higher grade section of 3.17 g Au/t and 0.91% Cu over 9.90 m core length (6.0 m true width). The hole intersected the main mineralized zone that was previously mined approximately 50 m southwest of the 4800 level in the former Hope Brook mine. The 4800 level is about 340 m below surface. This hole confirms that the main zone continues to the west of the underground workings and is open along strike in this direction. Many of the historic holes appear to have been too short to fully test the target zone hence the zone also appears to be open at depth.
The surface target zone extends along strike for at least 500 m and induced polarization geophysical surveys indicate that the favourable silicified zone extends to a depth of at least 100 m.
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 = 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. Dr. Chris Hale, P.Geo., Chief Geophysicist for Castillian and a qualified person as defined by NI 43-101 has supervised all geophysical work at Hope Brook and has reviewed and approved the scientific and technical content of this press release.
