The PACE Initiative Year 4 subsidised auger drilling programme undertaken on the Mount Hope (EL 3355) / Brimpton Lake (EL 3561) mineral exploration tenements was a trial to test the application of a new low cost drilling technique to exploring under shallow cover. It proved to be highly successful in profiling the basement geology across an area of 320 square km, in which no previous mineral exploration had been undertaken, at a cost of less than $200,000. In addition, the programme identified a new occurrence of the highly prospective Archaean Hall Bay Volcanics. The PACE drilling programme started on 16th of July and finished on the 5th of October 2007, after 178 auger holes had been drilled to an average depth of 15.5 m (total penetration 2770 m) along eight of the planned fourteen traverses. Approximately 50-60% of the holes were able to reach basement at depths of between 5 m and 20 m. A new basement lithology interpretive map has lately been constructed from the PACE drilling results, with the addition of data from previous drillhole basement intercepts in the surrounding region. This will be used to constrain the sites of further exploration for VHMS mineralisation within the Hall Bay Volcanics. The Hall Bay Volcanics appear to occur as a 5-10 km wide band trending north-eastwards at approximately 030°. This trend, when projected, would intersect the locations of the Oakdale / Malache zinc-lead-silver mineralisation recently discovered on Lynch Mining's EL 3301: it has been suggested that those occurrences may be some that have been remobilised from primary VHMS mineralisation. Connection to such a scenario is regarded as very encouraging for the prospectivity of the Hall Bay Volcanics on Mount Hope EL 3355. Lithogeochemical and SWIR spectroscopic analyses of Monax' PACE drillhole samples have confirmed the presence of saprolitic weathering products of mafic lithologies. Geochemical sampling of the basement rocks encountered has identified eight areas with base and precious metal values that are elevated above regional background levels. In the Mount Hope region Monax' results from sampling of subsurface calcrete have been shown to reflect elevated trace element values that are present in the basement, but further work is now required to determine the efficacy of surface calcrete sampling. The geochemically anomalous basement areas will be followed up with further drilling in 2008, after completion of an airborne EM survey to define areas of basement conductivity. While profiling the basement geology, the PACE drilling traverses also passed across several deep Cainozoic palaeochannels, which contain reduced sediments and thus have the potential for hosting roll-front uranium deposits. The PACE drillholes defined a system of these channels, which drains off the basement high near Mount Hope towards the north. It is interpreted to flow into the Yaninee palaeo-drainage system.
