Preliminary view of the data in an exploration drilling program on private farmland north of Wundowie revealed bauxite grades with 55% of holes containing available alumina grades of equal to 25% over greater than 2m thickness.
The program included 3,406 vertical holes drilled for 22,941.5m across an area of 2500ha which was completed by the end of last year with the aim of defining additional bauxite resources.
This work was undertaken on tenements E70/3159, 3900 and 4021 within the Bauxite Alumina Joint Venture (BAJV) with Yankuang Resources, where the mineralization was observed from within 0.5m of surface and consistent bauxite thicknesses of up to 16m were intersected.
Final analytical data for the program was obtained by BAJV in February and a preliminary review of the data has revealed that the mineralization may add significantly to current geological resources.
BAJV has commissioned a resource estimation study on a small number of large private landholdings and hired an external consultancy which expects to provide a JORC resource estimate in June 2012 after geological modeling is completed.
Bauxite Resources said results from the bomb analysis for greater than 25% available received till date reported total alumina within bauxite of up to 57%, available alumina between 25 – 56.5 % and available alumina:reactive silica ratios between 2:1 to 319:1 with reactive silica ranges from 0.1 – 15.4%.
