Iron Mountain finds high grade bauxite at Wandoo
Iron Mountain (ASX: IRM) has now received the final results from the maiden Wandoo bauxite drilling program, after a total of 287 air core holes were drilled in June 2010.
Assay grades as high as 47.9% Al2O3 were encountered with little or no recorded overburden, with results encouraging due to the extent and grade of the bauxite profile identified, and its proximity to existing road and rail infrastructure.
The program was across five freehold properties on the Darling Ranges Plateau within E70/2693, approximately 35km west of the township of New Norcia, in Western Australia.
The drilling was undertaken on a 200m x 200m grid, and approximately 250 holes were unable to be completed due to the onset of early seasonal rains and cropping season in the district.
Including quality control and check sampling, a total of 1311 assays were received intermittently in batches of 200 samples each since drilling was completed.
All assay data has been subsequently merged with all existing drilling data in preparation for the complete drilling database to be submitted to independent consultants Hackman & Associates for resource estimation study.
Reactive silica analysis utilising hydroxide leach technique is currently in progress, with a total of 512 samples selected and submitted for reactive silica analysis, with results expected to be received by late September.
Once completed, the reactive silica results will be merged into the maiden drilling database and resource estimation will commence.
