For Immediate Release Thursday 18[th] December, 2008
ASX RELEASE
HIGHLY ENCOURAGING MANGANESE BENEFICIATION RESULTS – WADDIKEE PROJECT, SOUTH AUSTRALIA
HIGHLIGHTS
-
Preliminary beneficiation studies confirm potential for raising the manganese content to 42% Mn – with recovery levels up to 88%
-
Spiral testing of bulk sample underway
-
Bulk sample from Pollinga prospect submitted for beneficiation test work
Monax Mining Limited (ASX: MOX) is pleased to announce preliminary results from manganese beneficiation test work on representative samples from its 100% owned Waddikee tenement on the Eyre Peninsula, South Australia (Figure 1). The studies were carried out on two homogenised bulk samples from Monax’s maiden drilling program at the Jamieson Tank Prospect.

During May and June 2008, Monax completed a reverse circulation (RC) percussion drilling program comprising eight traverses (44 holes) at the Jamieson Tank Prospect (Figure 2) and 4 separate holes at the Pollinga Prospect. Assay results confirmed the presence of manganese mineralisation in all eight traverses at the Jamieson Tank Prospect and in one drill hole at the Pollinga Prospect.

Representative samples from JTRC036 (8 to 13 metres) (623609mE, 6297159mN) and JTRC034 (14 to 21 metres) (624046mE, 6298466mN) were tested to determine their mineralogy using X-ray diffraction (XRD). Quantitative results from the XRD demonstrated that the predominant manganese oxide mineral is Cryptomelane (KMn8O16), with associated Quartz (SiO2), Kaolin (Al2Si2O5(OH)4) and Goethite (FeO(OH)). Samples JTRC036 and JTRC034 were also tested according to sieve screen sizing, with preliminary results indicating that the majority of the manganese is distributed within the coarser fractions (>0.2mm or 20µm) and that a significant amount of silica is lost to the fine fraction (<0.2mm or 20µm). It should be noted that the sample returned from the RC drilling method consisted of a finely ground powder which may affect the screen size optimisation results.
Subsequent to screen size optimisation, representative samples from JTRC036 and JTRC034 were passed through a heavy liquid separation (HLS) media. The heavy liquid (s.g = 3.32) effectively separates light minerals such as quartz and kaolin from the heavy manganese and iron minerals (e.g. Cryptomelane) which have a considerably higher density (s.g = 3.4 - 4.8). The heavy liquid separation was conducted under controlled laboratory conditions and does not necessarily reflect the outcome from a plant operation.
Preliminary heavy liquid beneficiation studies reveal that the manganese content can be raised to 42% Mn with 80% recovery for sample JTRC036, and to 34% Mn with 88% recovery for sample JTRC034. A summary of the results is provided in Table 1.

Spiral test work on the bulk sample from JTRC036 is underway, and a further sample from the Pollinga Prospect (PRC003 - 25 to 37 metres) has been submitted for beneficiation test work. A full account of the results will be released when then entire beneficiation test work has been completed.
Monax is highly encouraged by these preliminary beneficiation results. Significant scope remains for further manganese mineralisation at Jamieson Tank between drill traverses, at depth and along strike to the north and south.
