Magnetic Resources (ASX:MAU) Announces Excellent Metallurgical Test Results From Jubuk
Perth, April 27, 2010 AEST (ABN Newswire) - Magnetic Resources (
ASX:MAU) has carried out Davis Tube recovery (DTR) test work on a master composite sample from the recent RC drilling at Jubuk near Corrigin (ASX release 3 March 2010). The composite sample was compiled from four RC drill intersections over a 600m strike length of the Target 1 magnetite BIF, to determine the DTR sizing for future analyses.
The development test work showed that a 75 micron screen should be used as the DTR split size to give a sizing of 80% passing 53 microns for the test. This sizing was achieved in the test work. The finalised DTR test was performed, in triplicate, on the master composite giving the following results (See bottom of release for Results Table).
Jubuk Davis Tube Recovery Results
The iron grade, at close to 70%, is excellent and the low silica concentration in the concentrate, less than 2%, points to a quality, possibly Direct Reduction grade, product. These early test results indicate that the mineralisation at Jubuk can produce a high quality magnetite product at good iron recovery, and that the mineral assemblage liberates well, without the need for fine grinding.
Based on these highly encouraging results a 3500m RC drilling programme is planned, to infill and extend the drilling on the Jubuk outcropping crystalline magnetite BIF and to test the nearby Target 2, where recent ground magnetic surveys indicate a 3km-long core to the target obscured by soil cover.
Subject to permitting, the drilling programme is scheduled to commence in late May.
