Annual report for Great Northern EL 23516, for the year ending 3 April 2010

Abstract

During the current reporting period a desk top GIS review and data compilation commenced using information from open file reports to identify gold and base metal exploration targets for the 2010 field season. EL 23516 is located within the Pine Creek Orogen and much of the project area is made up of the Paleo-proterozic Burrell Creek Formation (Finniss River Group). There is a tendency for gold mineralisation to be focused in anticlinal settings within strata of the South Alligator Group and lower parts of the Finniss River Group. Most of the gold mineralisation in the region appears to be related to the I-type members of Cullen Batholith (Bajwah, 1994). Historical gold workings at Great Northern, Great Western and Star of the North are reported to have produced 112 kg of gold between 1896 and 1920, from small pits and shafts. The gold was found in concordant quartz veins and saddle reefs along the hinge-line of north-plunging anticlines. Between 1988 and 1993 The Goodall open pit mine of Western Mining produced 4,095 kg of gold, from ore with an average head grade of 1.99 g/t Au. The deposit (750m x 50m) consisted of a stock work of thin, conformable and cross-cutting quartz veins located some 60m east of a major anticlinal axis (Bajwah 2007). EL 23516 is still considered prospective for Au and base metal mineralisation and has been explored by a number of companies since 1973. The exploration program for the 2010 field season will include an infill airborne geophysics survey, rock chip and soil sampling programs with additional diamond and RC drilling planned, dependant on results.
