Boundary Zone
The geology at the Boundary Zone, as based on diamond drill logs, comprises predominantly intrusive rocks, mainly monzonites and occasional feldspar porphyries, post mineral pyroxenite porphyry dykes, and overlying post mineral volcanics. The intrusives appear to be irregular bodies, possibly hypabyssal, are variably potassically altered, and are cross cut by zones of brecciation, which are associated with magnetite-chlorite- calcite alteration, and copper-gold mineralization.
The Boundary Zone was discovered in 1993 and was extensively drilled between 1994 and 1997, prior to being acquired by Valley High Ventures in 2005. In 2006, Valley High completed additional diamond drilling, with intersections highlighted by hole L06-7 which cut 21m at 2.01%Cu +0.68g/t Au, and hole L06-9 which hit 20.4m at 0.87%Cu + 0.39g/t Au. In July 2008, Imperial Metals reported that exploration drilling on its portion of the Zone encountered high grade copper gold mineralization; Hole ND 08-42 returned 32.3 m @ 1.43% copper + 1.47 g/t gold and ND 08-44 returned 22.3 m at 1.56% copper + 1.21 g/t gold, with both holes being drilled within 100m of the property boundary.
