The Seabrook project is located on E77/2684, 42km northeast of Southern Cross in Western Australia’s Yilgarn region. ASQ have identified an epithermal quartz vein system that can be traced over 5km with up to 30m true width (Figure 2). Rock chip sampling has been carried out at various locations along the occurrence and multiple rounds of lab testing completed. Conventional crushing/scrubbing/screening processing has been compared with the flow sheet ASQ has been developing though in house R&D testwork. Samples collected in a manner considered representative of real-life mining conditions have returned grades of up to 99.97% SiO2, while a similar sample returned grades of 99.98% SiO2 using the R&D flowsheet (Tables 1 & 2). The details of this flowsheet are currently considered commercial in confidence.
The company believes the quartz vein has potential to produce HPQ products.

The next step in evaluating the Seabrook Hardrock Quartz project will be a drilling program to inform preliminary assessment of the quantity of quartz present and provide additional material for quality testing.
Environmental approval has been received from DMIRS for a reverse circulation drilling program. Before this drilling can take place, heritage surveys will need to be completed.
ASQ is also assessing the Seabrook tenement for other mineralisation potential. The lease straddles a +10km section of the Youanmi Greenstone Belt at the Koolyanobbing Shear Zone. Historic exploration has been carried out for tungsten, lithium, gold and iron ore. The Company is in the process of reviewing all available historic exploration data.
