Newmont Mining / Claude Resources conducted geophysical surveys (ground and airborne), geological mapping, trenching, and some diamond drilling at this Main Zone.
The mineralized Main Zone has been effectively traced by subsurface diamond drilling for over 500 metres and remains essentially open at both ends. It appears to have a strike length of at least 1km. The mineralized zone is dipping to the North, is roughly parallel to the foliation of the amphibolite and has been traced to depths of approximately 80 metres but has not yet been confined to a maximum depth. Widths of zones are varied, however, sampling was not conducted along the entire lengths of all drill core and it has been noted that mineralized zones can be easily overlooked.
Numerous drill sections show zones ranging from 0.50 m up to 7.5 m in width with higher grade sections on the order of 0.50 m, as defined by the sampling interval. The widest drill intersection thus far on the Ithingo Lake Main Zone area is 11.51 g/t (0.370 oz/t) over 7.5 metres (24.6 ft) or 29.01 g/t (0.846 oz/t) over 3.1 metres (10.17 ft) with visible gold in quartz veining and belongs to the #2 zone. This intercept was identified in DDH88-11 and correlated in DDH88-10 and DDH89-18 within the same cross section. This #2 zone is interpreted to run the length of the Main Zone.
The total number of significant mineralized zones identified in the vicinity of the Main Zone is 13. The Main Zone itself is defined by five zones (#1 through #5), or horizons, while the remaining six zones have been identified in drill core and flank the main zone to both the north and south. Zones #6 and #10 are located stratigraphically above the Main Zone and geographically to the north. Their full length and potential has yet to be properly tested. The remaining zones (#7 through #13) are all stratigraphically below the Main Zone and geographically to the south and have only been sampled so far in drill core. Dragonhead Bay to the NE has also been shown to have gold potential and several more VLF conductors have been identified in the area but not pursued as of yet.
