(CXX - TSX, CXZ - NYSE Amex),(\"Crosshair\") is pleased to announce that the first set of results from the metallurgical test work has been received from the Golden Promise Project in central Newfoundland, Canada. The Golden Promise Project is a joint venture with Paragon Minerals Corporation (TSX.V: PGR) (\"Paragon\"). A composite sample from six previously completed drill holes was submitted to SGS Mineral Services Vancouver, BC (\"SGS\") for preliminary metallurgical testing including gravity concentration, flotation and determination of the cyanide leaching characteristics.  Thirty-four (34) samples from the drill holes were composited to provide one sample of 34.4 kilograms with a head grade which assayed 4.5  g/t gold as compared to the weighted average historical assay grade based on the individual samples of 4.18 g/t gold.  The results indicate that the gold in the vein can be effectively recovered using gravity concentration in combination with flotation or leaching, or by direct leaching.  Gravity concentration recovers 85% of the gold at 120 microns and the remaining gold in the gravity tails can be recovered either by flotation after regrinding (96% rougher recovery at 110 microns) or by cyanide leaching (94% recovery in 72 hours at 70 microns).  The gold can also be recovered by direct leaching of the whole rock sample at 70 micron grind over a 72 hour period resulting in 98% extraction of the gold.\"It is very encouraging to see that the gold at Golden Promise is readily extractable\" says Stewart Wallis, President and CEO of Crosshair.  \"Further test work on the recently drilled holes will refine the extraction process ahead of our bulk sample.\"  Drill core samples from the 12 infill holes drilled this year in the central part of the Jaclyn Main Deposit are currently with SGS where additional metallurgical testwork will further define the extraction process flowsheet. Following a detailed review of the exploration data and metallurgical results, Crosshair and Paragon plan to conduct a surface bulk sampling program.  The bulk sample is aimed at providing a more representative gold gra...
