DMS TEST WORK AT BUTCHERBIRD YIELDS COMMERCIAL MANGANESE GRADES
-
First-pass dense media separation (DMS) test work yields up to 37.65% Mn in concentrate, using a separation S.G. of 3.4.
-
Grades >35% Mn returned from multiple 5m composite samples from zones at both Yanneri Ridge and Budgie Hill.
-
Results to date support an Exploration Target of 100-130 Mt @ 8-15%** manganese. Excellent potential to exceed this if other target areas return positive results.
-
9,000m RC and DD drilling programme commencing midOctober to support maiden JORC Resource Estimate.

KEY PROJECTS:
**It should be noted that the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to define a Mineral Resource, and that it is uncertain if further exploration will result in the determination of a Mineral Resource.
The Company is pleased to advise that very encouraging first pass DMS beneficiation test results have been received for composite material sampled from recent drilling at the Budgie Hill and Yanneri Ridge Prospects at the Butcherbird manganese project.

Grades of up to 37.65% have been achieved using a separation SG of 3.4, with favourable values for both phosphorous and iron, two key impurities in manganese ore. Work is ongoing to further investigate and refine the beneficiation behaviour of the material.
The work completed to date continues to define large tonnages of manganiferous material and beneficiation test data continues to show that the material from a number of identified deposits can be upgraded to commercial grades using routine techniques.
Drilling is expected to recommence mid-October to support a maiden JORC resource over selected subsections of the known mineralised areas which will form the basis for a scoping study to investigate the commercial parameters for developing a mine at Butcherbird.
Diamond drilling is expected to commence in early November to provide material for more definitive metallurgical testing which would normally be expected to yield better recoveries and potentially higher beneficiation grades than the work completed to date on RC chips.

| Table 1:XRF assay values of DMS fractions at 3.4 S.G. Analyses was performed on the >1.18mm fraction. Yield % values for each composite are calculated from mass recoveries. Composites which yielded concentrate grades >30%Mn are shown. 5 drill holes were selected for DMS test work. Each hole was further subdivided into approx 5m benches, based on geological boundaries. Each bench comprises 1m drilled intervals composited by the test lab. Each Composite was screened at 1.18mm to separate out the fines fraction, which comprises weathered clays and finely pulverised rock material. The composites were then crushed to achieve a grain size of between 1.18mm and 6.7mm. The feed material was run through the Dense Media Separation Cyclone at a S.G. of 3.4. The DMS Concentrate material comprises rock chips with S.G.’s greater than 3.4, while the DMS Tail constitutes material with S.G.s lighter than 3.4. The Concentrate and Tails were analysed using Fused Bead XRF to determine grades as reported. The fines fraction was not assayed due to the high clay contents. All testwork was undertaken by Nagrom, with specialised equipment suited to this small scale DMS study. |
