Dec 07, 2005 (G Seim) - DEL-82-4 was drilled on a 180 degree azimuth and an inclination of -45degrees. The hole intersected collared in variolitic iron tholeiite at a depth of 4 m. At 108.00 to 109.90 and 111.10 to 111.90 m graphitic tuff mineralized with quartz, pyrite, chalcopyrite and sphaleritied was intersected. The hole continued in iron tholeiite to a depth of 176.30 m where magnesium tholeiite was intersected. At 250.10 m the hole passed into intermediate tuff and continued in intermediate tuff to a depth of 405.2 m
