First High Power EM Results Symons Hill Fraser Range
Highlights
High powered fixed loop EM (HPFLEM) commenced in December 2014 with 3 loops (10%) of the Priority 1 survey area, completed.
Survey defines a late-channel conductor which closely corresponds with the VA15 VTEM target adjacent to highly anomalous near surface Ni values up to 1.2%Ni at SHG02.
Interpretation of the newly defined conductor at VA15 is currently underway to improve and refine this target for drilling.
A second potentially significant late-channel conductor has been discovered which extends beyond the eastern edge of the current survey block. Further surveys will be undertaken in the New Year, to map and evaluate this target.

Matsa Resources Limited
Matsa is pleased to report on progress of the large scale, high powered fixed loop electromagnetic (HPFLEM) survey which is now underway at Symons Hill. Heavy rain and thunderstorm activity in the area during November delayed the commencement of survey activities to early December.
The survey is being carried out as part of a research and development (R&D) project to develop/optimise HPFLEM techniques to explore for "Nova-Bollinger" style massive nickel-copper sulphide bedrock targets/conductors to a depth of more than 700m below surface.
Preliminary HPFLEM Survey Results
The immediate focus of initial surveying has been to repeat coverage over the VA15 VTEM target where earlier EM surveys in 2012 and 2013 returned ambiguous results. Planned Diamond drilling on this target was deferred in order to resurvey the target and potentially redesign drilling based on the final HPFLEM survey results.
Results have been received for 3 out of 97 planned survey loops of which 43 are designated priority 1 (SHP1_1, SHP1_2 and SHP1_3) as shown in Figure 1.
A preliminary interpretation of results by Southern Geoscience Consultants (SGC) on acquired data for loops SHP1_1 and SHP1_2has:
Identified a new conductor (moderate conductance 250-500S) which closely corresponds with and better defines the original VA 15 VTEM target; and
Identified a new conductor which is partly defined by surveying of Loop SHP1_2 (Figure 2).
Executive Chairman Paul Poli said "Matsa is encouraged that these results are demonstrating early success of the new technology incorporated into this high powered EM system. I look forward to seeing further results as they continue to unfold in the New Year."
HPFLEM Survey
As previously announced, the survey has been designed to test three successive, prioritised areas, commencing immediately on the highest priority target areas. Priorities have been assigned based on a number of targeting criteria (gravity, magnetic signatures, structural locations, strong Ni/geochemical anomalism) as well as a judgment as to the extent to which exploration to date has been hampered by conductive transported (palaeochannel) cover and/or deep conductive weathering. Information about the HPFLEM survey and other surveys carried out is provided in Appendix
1 and a location map of ground EM surveys carried out to date is provided in Appendix 2.
Discussion of Results
VA15: Gridded data for late channel HPFLEM data for loops SHP1_1 and SHP1_2 are compared with original helicopter borne VTEM data in Figure 2. It can be seen that the main NNW-SSE conductive trend on SHP1_1 data correlates with the VA15 VTEM target. The same trend is also evident in observed data for SHP1_2 data although the results are inverted (blue colour rather than magenta) given EM coupling from the opposite direction. A preliminary combined model based on the acquired data from both loops indicates a subvertical to steep east-dipping moderately conductive body (250-500S) at a vertical depth of around 300m. This is a similar amplitude to anomaly VA11 where drilling intersected disseminated copper sulphides at the modeled depth of the target conductor.
A second late channel conductor has also been identified. This conductor (magenta colour in the SE corner of Figure
2C) has only been partially defined at this stage. Additional HPFLEM surveying in this eastern/SE area is to be completed.

Experimental Component
Matsa's geophysical consultant (Russell Mortimer - SGC) and survey contract company (Outer Rim Exploration - ORE) were tasked with designing an optimised survey to "see" deeper than previous survey capacity. The technology being applied includes an innovative and experimental component, whilst using the best available technologies/methods. The experimental component is intended to:
Provide a suitable platform/active HPFLEM programme to allow CSIRO/RMIT to test and potentially commercialise new EM sensor developments.
Enable modifications/optimisation of EM transmitter and waveform design to enable routine, high power (150A) to be transmitted thereby increasing the effective depth of investigation.

Exploration results
The information in this report that relates to Exploration results, is based on information compiled by David Fielding, who is a Fellow of the Australasian Institute of Mining and Metallurgy. David Fielding is a full time employee of Matsa Resources Limited. David Fielding has sufficient experience which is relevant to the style of mineralisation and the type of ore deposit under consideration and the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves'. David Fielding consents to the inclusion in the report of the matters based on his information in the form and context in which
it appears.

Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other
locations used in Mineral Resource estimation.
Specification of the grid system used.
Quality and adequacy of topographic control.
|
EM survey loops and receiver data points are laid out using handheld GPS units to an accuracy of 3-5m
Topographic control 2-5m accuracy using published maps or
Shuttle Radar data is considered to be sufficient for modelling
of EM survey results.
|
Data
spacing and distribution
|
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity
appropriate for the Mineral Resource and Ore Reserve
estimation procedure(s) and classifications applied.
Whether sample compositing has been applied.
|
Loops are laid out as rectangles measuring approximately
1200x800m in a NS and EW direction.
Receiver data is acquired at 50m intervals along lines spaced at 150m
Survey lines are typically run parallel to the short electrode direction
|
Orientation
of data in relation to geological structure
|
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is
known, considering the deposit type.
If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have
introduced a sampling bias, this should be assessed and
reported if material.
|
The Transmitter loops and survey lines are carried out NS and
EW.
Geological strike is highly variable but dominated by a NNE "grain" which means that in most cases EM data is acquired at a high angle to geological strike.

Ground EM 2013, (See Location Plan below) carried out by Bushgum Holdings Pty Ltd, under supervision by Newexco consultants, consisting of both moving-loop (MLEM) and fixed- loop (FLEM) surveys. Data acquisition was achieved using a SMARTem24 8-channel geophysical receiver manufactured by ElectroMagnetic Imaging Technology (EMIT), Bartington 3- component magnetic field sensor (up to 1Hz frequency response) and a Zonge ZT-30 Loop Driver transmitter to power the loop with up to 30A. The MLEM and FLEM surveys are
both 400m wide. In the MLEM, the survey lines are spaced
400m apart with receiving stations every 100m inside the loop along an E-W direction. In the FLEM, the receiving stations are
50m apart across 1 km traverse in an E-W direction.
