ASX RELEASE
Parndana Project Update
HIGHLIGHTS
Soil sampling program completed
Preliminary portable x-ray fluorescence (XRF) results received
Coincident zinc and lead anomaly outlined
Monax Mining Limited ("Monax") (ASX:MOX) is pleased to provide an exploration update for its 100 per cent owned Parndana Project in South Australia (Figure 1).
Monax recently completed a detailed soil sampling program on the Vinco prospect, located approximately 1km east of the Bonaventura prospect, which are both part of the Parndana Project, on South Australia's Kangaroo Island.
Previous exploration at the Vinco prospect, included detailed gravity and induced polarisation (IP) surveys. Monax drilled two diamond holes targeting the main gravity anomaly and a chargeable anomaly defined by the dipole-dipole IP survey.
Further refinement using a gradient array IP (GAIP) survey outlined a prominent NNW
trending chargeable and resistive anomaly in an area not targeted by the diamond drilling.
Figure 2 shows the chargeability response from the GAIP survey and Figure 3 shows the resistivity anomaly outlined by the GAIP survey.
Figure 4 shows the combined lead and zinc soil results which show a strong correlation to the NNW trend of the GAIP anomalies.
"The new defined anomaly represents a genuine target for zinc and lead mineralisation similar to Bonaventura, and the next phase of drilling will target this feature," Monax Mining Managing Director, Mr Gary Ferris said.
"The correlation between the IP data and the soil results provides encouragement that this newly defined anomaly potentially represents a zone of mineralisation," he said.
Monax is planning a drilling program at its Parndana Project in the first half of 2015.

Background
Monax's Parndana Project is located at the flexure within the Cygnet Snelling Shear Zone (CS- ZS), a prominent east-west trending crustal scale structure. The CS-SZ is the interpreted
southern margin of the Gawler Craton, and is marked by a clear zone of low magnetic intensity.
Mineralisation at Bonaventura comprises NNE trending zones of coarse sphalerite (zinc sulphide) and galena (lead sulphide) bearing quartz vein stockworks and disseminations within a silicified sandstone host rock. Exploration to date has focused around historical workings and near surface mineralisation.
Drilling by the former SA Department of Mines and Energy in 1990 reported several encouraging intersections of mineralisation in the Bonaventura area including:
16m (10-26) @ 2.69% Zn, 0.45% Pb & 1.7 g/t Ag including 5m (16-21) @ 5.8% Zn (Hole
GRA 7).
(This information was prepared and first disclosed under the JORC Code 2004. It has not been updated since to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported. Note: all lengths are downhole lengths; true width unknown).
Exploration by ASX-listed Havilah Resources at Bonaventura in 2003 involved a shallow drilling program which produced further encouraging results including:
7m (14-21) @ 1.32% Zn, 3.16% Pb & 3.81 g/t Ag including 2m (16-18) @ 3.59% Zn,
9.46% Pb & 10 g/t Ag (Hole PRC01),
18m (30-48) @ 1.69% Zn & 1.81 g/t Ag including 6m (42-48) @ 3.48% Zn, 0.51% Pb &
1.4 g/t Ag (Hole PRC04), and
5m (26-31) @ 26.9% Zn, 10% Pb & 1.54 g/t Ag (Hole PRC31).
(This information was prepared and first disclosed under the JORC Code 2004. It has not been updated since to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported. Note: all lengths are downhole lengths; true width unknown).
Monax undertook drilling programs at Bonaventura in 2006 and 2008 aimed at understanding the structural setting to better target high-grade zones (see ASX Release 27 March 2014 for drill hole details). Significant intersections from the 2006 drilling program include:
6m (52-58) @ 1.96% Zn & 0.26% Pb including 2m (54-56) @ 3.65% Zn (Hole BVRC02),
4m (16-20) @ 2.06% Zn & 2.15% Pb (Hole BVRC03),
16m (34-50) @ 3.43% Zn & 0.66% Pb including 6m (40-46) @ 6.3% Zn (Hole BVRC03),
23m (62-85) @ 1.16% Zn (Hole BVRC08 - ended in mineralisation),
1m (56-57) @ 3.3% Zn & 4.58% Pb (Hole BVRC10),
4m (91-95) @ 3.94% Zn including 1m (93-94) @ 7.1% Zn (Hole BVRC10),
23m (98-121) @ 1.22% Zn (Hole BVRC10 - ended in mineralisation); and
1m (76-77) @ 2.31% Zn & 1.09% Pb (Hole BVRC11).
(This information was prepared and first disclosed under the JORC Code 2004. It has not been updated since to comply with the JORC Code 2012 on the basis that the information has not materially changed since it was last reported - see Monax ASX Release 24 July 2006 for details. Note: all lengths are downhole lengths; true width unknown).
Significant intersections from Monax's 2008 drilling program include:

29.9m (16.1-46) @ 1.79% Zn including 10m (27-37) @ 3.22% Zn, 1.62% Pb & 1.53 g/t
Ag; and 3.9m (16.1-20) @ 2.13% Pb & 2.04 g/t Ag (Hole BVDD004)
10m (81-91) @ 2.13% Zn, 0.45% Pb & 0.83 g/t Ag including 6m (85-91) @ 2.97% Zn,

Sampling techniques

|
|
Soil samples comprised bulk samples collected at a nominal depth of
10-30cm depth on a 25m x 25m grid within the central area of interest grading to a 50m x 50m grid on the edge of the grid area.
Bulk samples were sieved to remove the >3mm (coarse) fraction.

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
Criteria
JORC Code explanation Commentary
Mineral tenement and land tenure status
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.
The soil sampling program was undertaken on Exploration Licence
4581 which is owned 100% by Monax Mining Limited. The tenement is located on Freehold Land.
The tenement is free of any known impediments.
Exploration done by other parties
Acknowledgment and appraisal of exploration by other parties. Initial drilling in the Bonaventura area was undertaken by the South Australian Department of Mines and Energy in 1991. Havilah Resources undertook regional soil and stream geochemical surveys, followed by a drilling program in 2003. Several companies prior to
1990 undertook soil sampling programs in the region. No evidence of any mineral exploration at the soil sampling site has been reported.

The assumptions used for any reporting of metal equivalent values should be clearly stated.
No metal equivalent values have been reported.
Relationship between
mineralisation widths and
intercept
lengths
|
|
These relationships are particularly important in the reporting of
Exploration Results.
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').

|
Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being
reported These should include, but not be limited to a plan view of
drill hole collar locations and appropriate sectional views.
|
|

|
Balanced
reporting
|
|
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of
Exploration Results.
|
|
Only results relevant to the discussion on the style of mineralisation
presented.

Other substantive
exploration data
|
|
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical
survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density,
groundwater, geotechnical and rock characteristics; potential
deleterious or contaminating substances.

Data from previous exploration has been previously released..

Monax will review newly acquired data to assist in determining the
next phase of exploration.
