44 5 - Independent Geological Report - Australia Vredefort - Witwatersrand and the Sudbury impact structures are the best-known such impacts - housing world-class ore deposits of Au, U and Ni, Cu, PGE (platinum group elements) respectively. Closer in crater-size (some 11 km in diameter) and commodity type is the Ternovka meteoric structure located in the Proterozoic fold belt of the Krivoi Rog Basin, Ukraine, where both iron ore and uranium have been mined (Grieve 2005). 2.1.4 Geology and Mineralisation The Shoemaker Impact Structure (formerly known as the Lake Teague Ring Structure) - over which the ELs have been granted - lies on the southern edge of the Palaeoproterozoic Earaheedy Basin, which overlies the northern margin of the Archaean Yilgarn Craton. Figure 2: Northern Shoemaker iron targets shown against 1:250,000 Earaheedy geology map (top), Galaxy gravity image (middle) and regional TMI image (bottom).
The Earaheedy Basin follows the Hamersley Basin in significance as far as iron oxide deposition is concerned. Two iron formations are found within the Earaheedy Basin – a Banded Iron Formation (BIF) and a Granular Iron Formation (GIF). These are interbedded with shales and exhibit local areas of iron enrichment. Both iron formations are present within the Shoemaker tenements. Mapping by Amax Exploration in 1978 identified up to eight (8) zones of hematite-goethite occurring within the Frere Formation. These zones ranged in thicknesses from 5 metres up to 97 metres. The Amax geologists drew lithologic-stratigraphic parallels between the apparently similar iron formations of the Hamersley and the Earaheedy Basins. Zone 1, which was only identified immediately to the south-east of the Shoemaker Impact Crater (then known as the ‘Nabberu Dome’), was between 36m and 97m thick, and a strike length of 8 kilometres was inferred; assays with an Fe content averaging 61.2% over 58 metres have been obtained, with overall low grade contaminants of 0.02% P and 0.09% S. None of the iron zones found within the Shoemaker Project could be assigned to any of these stratigraphic zones - possibly due to deformation of the strata following the impact event. Seven samples taken by Amax at the north-west of the Shoemaker rim structure within the current project area returned Fe-assays between 55.6% and 69.6% with low phosphorus content. Work conducted by the Geological Society of Western Australia (Piranji 2005) uncovered significant evidence of post-impact hydrothermal activity arising from the Shoemaker impact event. This includes early, high-temperature alkali metasomatism at deep levels, resulting in granitoid rocks of syenitic affinity and alkaline composition, with strong enrichment in Na O, K O, Rb, Sr, Y, Zr, Nb, Ba and REE (Rare Earth 2 2 Elements); it also includes a later, lower temperature metasomatism at higher levels, manifested in overprinting by hydrous mineral assemblages. Pervasive silicification of the Yelma Formation, partial silicification, cross-cutting quartz-veining in NE-trending impact-related fractures and pods of chert and jasperoidal quartz within the granular iron beds of the Frere Formation bear witness to the later phases of this hot spring activity. 2.1.5 Potential There is ample evidence proving Shoemaker as an impact structure (Pirajno 2002, 2005). Thus the next step is to seek out the potential economic benefits of an impact. Hawke (2003) reports impact-related hot spring activity from the southern flank of the structural uplift of the Shoemaker Impact Structure. The same author (2004, p. iii) notes that it is “… located in an area of known base-metal, iron and gold occurrences and is prospective for progenetic and hydrothermal deposits…” (see fig 4.) The Shoemaker Iron Ore Project represents an exciting exploration target for iron ore. Whilst the threshold for an iron ore project in this region of Western Australia to be deemed economically viable is considered high, there is scope for this project to meet that threshold. There has been – obviously - surface enrichment of iron content in the Frere formation (with lower-grades to be expected at depth), yet it is also likely that the impact-alteration may have led to higher grades. Significantly, the Shoemaker project appears to contain the most extensive outcrops of iron enrichment compared to other areas of the Frere Formation. Geophysical surveys indicate that large gravity high anomalies, coincident with mapped outcrops of iron enrichment, present potentially large exploration targets. Iron ore is not the only commodity for this project. A compilation of the economic potential of the region (Abeysinghe 2005, Fig. 36) shows the Shoemaker project area being prospective for - Iron: supergene-enriched granular ironformation; - Gold: hydrothermal-vein mineralization; - Base metals: strata-bound-sedimentary carbonate-hosted mineralization; - Uranium: “Calcrete areas and palaeochannels associated with or adjoining the Shoemaker impact structure are prospective for uranium mineralization” (Abeysinghe 2005, p. 51). 2.1.6 Shoemaker Proposed Exploration and Budget Initial work is to focus on defining and prioritising iron ore drill targets through field-work, to be followed by drilling of these targets. A heritage survey should be completed prior to drilling. Further gravity surveys covering the south-eastern corner of the project area and the western edge of the Shoemaker Structure are also proposed to be undertaken. Of particular significance, the gravity-high anomalies appear to be co-incident with magnetic lows, indicating higher hematite enrichment. Several large magnetic lows occur in the south-east corner, which may represent further gravity targets - and if due to hematite rich iron formations - may offer considerable strike potential. <strong>General</strong> <strong>Mining</strong> Corporation Ltd ~ Prospectus 45
