Matsa is pleased to advise that it has achieved a JORC 2012 compliant resource estimate for the Fortitude Gold Deposit which forms part of the Lake Carey Gold Project.

A resource estimate for Fortitude was originally completed by Runge Limited (“RPM”) in February 2010 under instruction from the previous owners, Midas Resources Limited (“Midas”). Matsa appointed CSA Global Pty Ltd (“CSA Global”) to conduct an audit of that resource and bring the resource up to a JORC 2012 compliant level.

The Mineral Resource block model and data was imported into Surpac by CSA Global. A detailed audit of the mineral resource estimate was undertaken which included:

  • Review of relevant input data

  • Review of the geological interpretation

  • Review of wireframe construction methods

  • Analysis of basic statistics, composite extraction and high grade cuts

  • Review of the grade estimation process, block model construction and other methodologies

  • Confirmation of the reported Mineral Resource from the block model.

Results

As a result, CSA Global have confirmed the Fortitude Mineral Resource and is reported below in accordance with the 2012 JORC Code.

Geology and Geological Interpretation

Gold mineralisation is associated within the Fortitude Shear Zone, a north-northwest striking D3 shear which extends the length of the Lake Carey project. Primary mineralisation is characterised by near vertical, sheeted quartz veins hosted within the Fortitude Shear (Figure 1). Vein intensity is highly indicative of mineralisation tenor, although more carbonate rich veining is much less prospective than quartz dominated veining. Veining is locally brecciated, or laminated in thicker units, but is generally massive. Sulphide minerals include pyrite +/- arsenopyrite. The occurrence of strong quartz veining with sulphide minerals, fuchsite or intense sericite alteration is indicative of better Au grades.

Secondary mineralisation is characterised by flat lying supergene lodes (Figure 2).

Drilling Techniques

Drilling supporting the Mineral Resource was predominantly Reverse Circulation (RC) with a minor number of diamond and aircore (AC) drill holes. The Mineral Resource estimate is based on assay data

Page 2

==> picture [596 x 60] intentionally omitted <==

----- Start of picture text -----

Matsa Resources Limited
----- End of picture text -----

from 17 RC/diamond holes, 173 RC holes and 80 AC holes. AC holes represent 28% of the total drill holes used in the resource, and only 13% of the intersection metres used for the estimate.

Sampling Techniques

For RC drilling the 1 metre bulk samples were collected in plastic RC bags prior to being passed through a Jones riffle splitter. Diamond core was marked up and logged prior to being cut with half the core being submitted for analysis.

Sample Analysis Method

50% of the assays completed were by fire assay with a 50g charge. The remainder was completed by aqua regia analyses. ALS, Genalysis and Ultra Trace laboratories were used.

Estimation Methodology

The deposit was estimated by using Ordinary Kriging (OK) grade interpolation using Surpac software. The wireframes were applied as hard boundaries in the estimate.

The block dimensions used in the model were 12.5m NS by 5m EW by 5m vertical with sub-cells of 6.25m by 1.25m by 1.25m. A high grade cut of 30g/t Au was applied to supergene composites, while a high grade cut of 25g/t Au was applied to the shear hosted mineralisation composites used in the resource.

Bulk densities assigned to the model ranged from 2.0t/m[3] to 2.9t/m[3] based on weathering state and lithology.

Cut-off grades

Wireframe and geological modelling was prepared using a nominal 0.5g/t Au cut-off grade for primary, shear- hosted mineralisation and 0.3g/t Au cut-off for supergene mineralisation. The Mineral Resource has been reported at 1.0g/t Au cut-off and has been based on assumptions about economic cut-off grades for open pit mining from current mining operations in the region.

Mineral Resource Classification

The classification of Indicated and Inferred was made on the basis of continuity of structure and drill spacing. The Mineral Resource estimate appropriately reflects the view of the Competent Person.

located just west, forms a narrow corridor of ESE trending greenstones
which are bounded to the east and west by granitoid terrane. As the
Fortitude-Bindah system extends north the greenstone pile thickens
and lies host to numerous large gold mineralisation systems. To the
south the Fortitude-Bindah system appears to attenuate and
eventually terminate against granitoids of the Eastern Gneiss Terrane.
The greenstone sequence located within the Fortitude tenement is
comprised of highly foliated felsic to intermediate volcanic rocks with
relatively undeformed mafic volcanic units to the east and west in
contact with granite. The whole greenstone package varies in width
from <2km at the southern end of the tenement to approximately
8km at the northern end. Major north to north-northwest trending
shear zones occur within the greenstones and the granite to the east,
in particular along geological contacts. The main structural features
are the Fortitude Shear along the eastern intermediate-mafic contact
and the more north- westerly trending Bindah Shear, along the
western intermediate-mafic contact
Gold mineralisation is typically associated with the Fortitude Shear
Zone, a north-northeast striking dextral shear which extends the
length of the Lake Carey tenement. To the north, it horsetails into the
Wilga fault system and in the south it continues into the Kirgella
Gneissic Dome. Gold mineralization is also associated with the Bindah
Shear, particularly at the old Bindah Mine to the southwest.
The Fortitude deposit is hosted within sheared felsic to intermediate
volcanic rocks and minor ultra mafics, and is covered by up to 10m of
lacustrine clays and aeolian sands surrounding Lake Carey. Gold
mineralisation occurs within a steeply dipping shear system, and is
associated with pervasive carbonate-sericite-silica alteration along
with pyrite-arsenopyrite mineralisation. Remobilisation of gold has
also resulted in the formation of flat lying zones of supergene
mineralisation within the regolith. Weathering extends to a depth of
60-80m.

Regolith wireframes were created by Runge using the interpreted
weathering strings as supplied by Midas. Wireframes for the bottom
of complete oxidation, top of saprock, and the top of fresh rock were
generated.
Runge’s resource modelling is within the interpreted gold grade
envelopes, using a nominal 0.5g/t Au cut-off grade for the shear
hosted mineralisation, and a nominal cut-off for the supergene of
0.3g/t Au. These cut-offs were selected as they represent inflections in
the cumulative population distribution and enabled the mineralisation
to be captured in a coherent envelope, which agreed with the
geological model.
Dimensions The extent and variability of the Mineral Resource expressed as length The Fortitude Au deposit extends for approximately 1.5km in a NNW-

extended to a maximum of 400m below surface. The individual high
grade shear hosted lodes are upto 20m wide.

  • Estimation andThe nature and appropriateness of the estimation technique(s) applied and modelling key assumptions, including treatment of extreme grade values, domaining, techniques interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used.

  • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data.

  • The assumptions made regarding recovery of by-products.

  • Estimation of deleterious elements or other non-grade variables of economic significance (eg sulphur for acid mine drainage characterisation).

  • In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed.

  • Any assumptions behind modelling of selective mining units.

  • Any assumptions about correlation between variables.

  • Description of how the geological interpretation was used to control the resource estimates.

  • Discussion of basis for using or not using grade cutting or capping.

  • The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available.

  • Statistical analysis was performed on the supergene and shear hosted mineralisation domains respectively using Supervisor software. Based on population histograms and the coefficient of variation statistic it was determined that a high grade cut of 30g/t Au (99[th] percentile) was appropriate for the supergene domain, while a high grade cut of 25g/t Au (99.5[th] percentile) was more appropriate for the shear hosted mineralisation

  • The data from the main domains for both supergene (Object 9) and shear hosted mineralisation (Object 101) were each used for variogram modelling.

  • Using parameters derived from modelled variograms, Ordinary Kriging was used to estimate average block grades in 4 passes using Surpac software. The wireframes were applied as hard boundaries in the estimate.

  • Runge completed an Inverse Distance (ID[2] ) check model and found the OK estimate to be within 1% of the ID model for Au ounces.

  • Previous resource estimates were reviewed for comparison by Runge but not factored into the current resource estimate.

  • By-product recovery was not included.

  • No significant deleterious elements were evident in the assay data.

  • Parent block size of 12.5m NS by 5m EW by 5m vertical with sub- cells of 6.25m by 1.25m by 1.25m. The parent block size was selected on the basis of 50% of the average drill hole spacing

  • Ordinary Kriging (OK) grade interpolation with an oriented ‘ellipsoid’ search neighbourhood was used to estimate Au in the block model. Search ellipsoid was oriented to the average strike, dip and plunge of the mineralised zones. A first and second pass search radius of 50m and 100m respectively was used with a minimum sample number of 10 and a maximum sample number of 40. The search radius was increased to 200m and 400m for the third and fourth passes respectively. The minimum number of samples was set to 4 for the third pass and 2 for the fourth pass. In passes 1, 2 and 3 a restriction of 5 samples per drill hole was applied, increased to 10 for pass 4. Approximately 54% of the blocks were filled in the first two passes, and 99% in the first three. Cell discretization was 3 (X) by 4 (Y) by 3 (Z).
