Additional to its earlier ASX bulletins (listed under), AusQuest Restricted (ASX: AQD) is happy to advise that it has efficiently produced a premium iron product grading >70% Fe from DTR take a look at work accomplished on samples from 14 of the 16 drill-holes on the Waterfall Prospect, a part of its 100%-owned Morrisey Venture in Western Australia’s Midwest mining district.
Key Factors:
- Premium grade iron product (>70% Fe) has been produced throughout the Waterfall Prospect by beneficiation take a look at work utilizing the Davis Tube Restoration (DTR) methodology.
- Magnetite was liberated from its host rock utilizing a comparatively coarse grind measurement of 75um and 106um, which suggests potential financial savings on future processing prices.
- Common DTR recoveries of roughly 34% point out that almost all, if not all, of the magnetite has been recovered within the focus.
- Impurity ranges (silica, alumina, sulphur and phosphorus) throughout the magnetite focus are extraordinarily low.
- The Morrisey Venture is effectively situated, being ~120km by highway north of Mullewa after which ~80km by rail to the Port of Geraldton.
- Waterfall is the primary of not less than 5 targets recognized throughout the Morrisey Venture, with potential to host magnetite mineralisation.
Subsequent Steps:
- Native Title clearance surveys over additional magnetite targets are scheduled to be accomplished later this yr.
- Drilling of extra targets is being deliberate for 2025, below the Strategic Alliance Settlement with a subsidiary of South32 Restricted.
Beneficiation take a look at work utilizing the DTR methodology confirmed wonderful recoveries of magnetite from its host rock (averaging ~34%) throughout the prospect, utilizing coarse grind sizes of 106um and 75um, highlighting potential for the prospect to ship a premium iron (Fe) product with very low impurity ranges and enhancing the long run industrial potential of the Venture.
The Morrisey Venture is effectively situated, being ~120km by highway north of the city of Mullewa, and an extra 80km by rail to the Port of Geraldton (Determine 1). No discussions have been held with transport suppliers at this stage.
Determine 1: Morrisey Venture: Location Plan displaying highway and rail entry to the Port of Geraldton.
DTR outcomes for all remaining drill-holes have now been acquired, confirming that iron (Fe) grades larger than 70% Fe might be achieved from each the 75um and 106um grind sizes for all of the composite samples (various from 4m to 12m in size). The distribution of DTR grades and down-hole thicknesses for the 75um grind measurement is proven in Determine 2, with cross-sections offered in Figures 3 and 4.
Whereas there are not any vital variations between outcomes from the 2 grind sizes used, outcomes for 75um are barely extra constant, with much less variations than for the 106um knowledge (see Tables 1 and a couple of under).
DTR Fe grades for the 75um grind measurement range from 70.25% Fe to 71.63% Fe with recoveries various from 18.6% for the decrease grade composite samples (35percentFe), with a median restoration of magnetite throughout the prospect of ~34%.
Deleterious parts for the 75um product had been all very low, together with silica (common 1.3% SiO2), alumina (common 0.19% Al2O3), sulphur (common 0.08% S) and phosphorous (common 0.004% P), solely growing barely for the coarser grind product.
Petrological examination of chosen samples signifies that the magnetite grains are extremely fractured, which is prone to contribute to the wonderful magnetite recoveries achieved by way of the DTR take a look at work.
Related magnetic and gravity anomalies to the Waterfall prospect happen at various places throughout the Morrisey Venture. 5 targets have been recognized for drilling to assist decide the general magnetite potential of the district.
