D'Aguilar Gold Limited (ASX:DGR) Exploration Update On The Monogorilby Iron And Titanium Prospect
Brisbane, Oct 27, 2009 AEST (ABN Newswire) - The Directors of D'Aguilar Gold Limited (ASX:DGR) are pleased to provide an update on the Monogorilby iron and titanium prospect held by subsidiary Ridge Exploration Pty Ltd.
Ridge Exploration Pty Ltd has been undertaking evaluation of iron formations in the Surat Basin since May 2008, and identified a large iron ore prospect at Cadarga, 100 km south west of Mundubbera and 80 km east of Wandoan. An area in excess of 200 square km has been delineated containing > 30% iron in rocks.
Mapping and sampling work in the Cadarga area led to the discovery of high grade titanium dioxides (to 31% TiO2) around an interpreted basaltic volcanic centre near the town of Monogorilby 25 km east of Cadarga. The prospect is flat lying within a lateritised volcanic breccia and covers approximately 6 square km around a diatreme style of volcanic vent. The prospect appears to be up to 10 metres thick, with the outcropping top 1-2 metres thick high grade mineralised material grading 10 - 31 % TiO2.
Following considerable delays at an independent laboratory, Ridge has recently received a preliminary report on the mineralogy of a sample of Monogorilby material submitted for Mineral Liberation Analysis (MLA) and Quantitative X-ray Diffraction (QXRD). The chemical assay of the sample is shown in Table 1 below:
Sample Al2O3 Fe2O3 SiO2 TiO2 22.4 45.2 3.66 16.95 Table 1: Chemical Assay Data (Wt%)
While the report indicates the constituent minerals are present within complex textures, the titanium component has been clearly identified as predominantly rutile (TiO2) with goethite (FeO(OH).Fe2O3). The iron component is primarily hematite, with goethite; the aluminium component is predominantly gibbsite.
Ridge Exploration believes it will be possible to separate the key mineral components by physical and chemical methods, and with the potential tonnage of material available at Monogorilby further work can now be undertaken. Drums of representative material are presently being collected from the prospect for metallurgical test work.
