Bridging report EL 10347 Burnside Project - Golden Dyke Dome 15 April 2010 to 15 January 2011

Abstract

EL 10347 is one of the significant tenements located 145km SE of Darwin, and is centered on the Golden Dyke Dome, a faulted anticlinal feature at the southern end of the historic Yam Creek-Golden Dyke gold-mineralised belt. Several historic gold mines occur within the tenement including Golden Dyke, Davies No 2, Fishers Adit, Afghans Gully and Langley's. Gold mineralisation in the tenement is associated with the middle Koolpin Formation of the South Alligator Group. Prospects lie along an arcuate fold axis trend, (Good Shepherd Anticline) which is parasitic to the west limb of the Dome. The gold closely follows stratigraphy and the bulk of mineralisation is confined to the contact zone between the Koolpin Formation and the Zamu Dolerite. It is hosted mainly by dark, nodular, cherty, chloritic and magnetic iron formation horizons thought to correlate with the same strata at the Cosmopolitan Howley Mine 16km to the west. Several gold bearing localities, within or close to the tenement, have been worked intermittently since 1872. These are listed as the Golden Dyke Mine, Davies No.1, Fishers Lode, Corbetts, Langleys, Black Rock Shaft and Afghans Lode. Base metal occurrences have been recorded near the eastern boundary of the EL and along the Golden Dyke trend. Heatley's Prospect includes lead-zinc and copper occurrences. The Davies Creek Prospect is a reported lead-zinc occurrence. Exploration on EL 10347 was conducted by JV partner Thundelarra Resources who carried out a field reconnaissance mapping for uranium, on the western flank of the Golden Dyke Dome deposit. Mapping identified doleritic rocks, tourmalinites, quartztourmaline veins and sulphides north of the Fishers Lode pit. Similar lithological units have been found around the Thunderball deposit, highlighting the uranium potential for this tenement. During the next reporting period, Crocodile Gold will conduct regional scale geophysical and geochemical surveys over the Burnside Project area, part of which will cover EL 10347.
