INTRODUCTION
Matsa Resources Limited (“Matsa” or “the Company” ASX: MAT) is pleased to report on its exploration and corporate activities for the quarter ended 30[th] September 2016.
Background information about the methods and data used in compiling this report, are attached as Appendix 1 in accordance with the JORC 2012 Code.
COMPANY ACTIVITIES
LAKE CAREY GOLD PROJECT
The Lake Carey gold project area which consists of 12 tenements covering an area of 128km[2] was acquired by Matsa during the quarter from the liquidators of Fortitude Gold Pty Ltd. Mineral Resources at Fortitude were defined at the time of acquisition under JORC 2004 guidelines and comprise 6.289Mt @ 1.9g/t for 385,300oz (MAT announcement to the ASX 22[nd] July 2016) .
The project package which includes the Lake Carey, Phantom Well and Wilga projects are located approximately 220km northeast of Kalgoorlie-Boulder and 70km south of Laverton within the north-eastern goldfields of Western Australia. The acquired project area is located in the highly productive Laverton Tectonic Zone (LTZ) 25km south of AngloGold Ashanti’s Sunrise Dam gold mine, 60km south of the Granny Smith gold mine and 12 km south of the Red October gold mine (Figure 1).

Figure 1: Lake Carey Project on Aeromagnetics
Matsa acquired the Lake Carey project due to its excellent potential for near term production and a very favourable return on investment. The Fortitude project has a number of significant advantages including:
-
granted mining licences;
-
excellent existing haul roads and nearby processing facilities;
-
comprehensive database, and development studies to provide a fast track to production; and
==> picture [596 x 56] intentionally omitted <==

----- End of picture text -----
- strong exploration upside potential with identified targets and proximity to several world class gold deposits.
It is Matsa’s intention to commence mining at Fortitude with treatment by a local third party processing facility. Discussions on favourable terms with processing facilities are at an advanced stage. Purchase and mine development costs are to be funded from Matsa’s existing cash and liquid assets.
Exploration potential within the combined project area is considered excellent with initial high priority targets at Bindah and Galant which could increase short term production potential. Historically, the highly prospective Fortitude and Bindah Shears are under-explored with mostly wide spaced shallow aircore drilling. There is consequently excellent potential for Matsa to make new gold discoveries.
Strategically, the Lake Carey gold project is an excellent geographical fit with Matsa’s adjoining Mt Weld gold project with a combined project area of 340km[2] (Figure 1).
Work Completed in the Current Quarter
The aggressive work programme which commenced during the quarter, is targeted on progressing the project through to production as quickly as possible (Figure 2). The following activities were carried out during the quarter:
-
Acquisition of E39/1863 and E39/1864;
-
A total of 21 diamond drill holes for 2292.9m were completed to validate and enhance the resource model, provide additional metallurgical samples and provide geotechnical data for mine design;
-
A total of 5 water bores were completed for 518m;
-
The Fortitude resource model was comprehensively reviewed with the resource estimate upgraded to comply with 2012 JORC code guidelines;
-
Advanced discussions were held with owners of nearby treatment plants;
-
Detailed Fauna and Flora surveys commenced within the mining project area of interest; and
-
Exploration targets were developed and ranked by experienced consultant.

Diamond Drilling
Drilling commenced during the quarter and is nearing completion with 17 drill holes completed (Figure 2, Table 1). Drilling was carried out using a truck mounted Hydco diamond drill rig. Diamond coring commenced at the base of unconsolidated surface materials (typically a depth of 1-6 metres) employing the triple tube technique to maintain core integrity particularly in the weathered profile and in zones of strong fracturing.

Table 1: Fortitude Project Diamond Drilling 2016
Logging and sampling of diamond drill core is in progress and it is anticipated that assays and other results from the drilling programme will be incorporated into the project study before the end of the year.
Water Bore Drilling
Five water bores were completed, four were developed into production bores and one was converted to a monitor bore in order to manage and monitor ground-water inflow and recharge rates within the Fortitude mine study area. Pumping flow-rate and water level data are currently being measured with results expected to be incorporated into the ongoing study before the end of the year.
Resource upgrade to JORC 2012
The original resource estimate of the Fortitude deposit was carried out in 2010 by Runge Limited under instruction from the previous owners, Midas Resources Limited (MAT announcement to ASX 22[nd] July 2016) .
Matsa, as recently announced, appointed CSA Global Pty Ltd to audit that resource and bring the resource up to a JORC 2012 compliant level (MAT announcement to ASX 1[st] September 2016) .
The upgrade involved re-importing the Mineral Resource block model and completing a detailed audit of the mineral resource estimate with particular emphasis on:
-
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; and

Geology and Geological Interpretation
Gold mineralisation is associated with 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 along the sheared contact between intermediate volcanics in the west and a package of highly deformed ultramafic rocks to the east (Figure 3). The occurrence of strong quartz veining together with sulphide minerals is indicative of better Au grades. Sulphide minerals include pyrite +/- arsenopyrite. Secondary mineralisation is characterised by flat lying supergene lodes.
Resource Estimate
The Fortitude gold deposit contains a global JORC 2012 Indicated and Inferred Mineral Resource Estimate of 6,289,000t @ 1.9g/t for 385,300 ounces as announced by Matsa to the ASX 1st September 2016. There has been no material change in the resource figures since that announcement.

Metallurgical
Discussions are well advanced with several local treatment plant owners. Metallurgical sampling is being carried out in collaboration with nearby operators in order to determine likely gold recoveries for different ore types, as the basis for an ore sales or toll milling agreement. Metallurgical results awaited.
Detailed Fauna and Flora surveys
Fieldwork was completed and laboratory and associated research is currently underway. No adverse issues were encountered and it is expected that results will provide strong support for a positive outcome for the ongoing mining study before the end of the year.
Review of Exploration Potential
This review was focused on the potential to increase the resource base for the Fortitude project through targeted exploration. The review took advantage of the comprehensive drilling and exploration database and previous reports which Matsa acquired with the Fortitude Project. The review was carried out by Simon Rigby of Beaumont Consulting who was able to apply his detailed knowledge of gold mineralisation in this prolific gold district. Key recommendations were as follows (Figure 3):
-
Early drill-testing of known gold mineralisation at Bindah and Galant because of their potential to contribute additional gold resources in the short term;
-
Aircore drilling along the NW extension of the Bindah shear where sparse and broad-spaced past drilling achieved some anomalous gold intercepts including 4m @ 0.87g/t Au and 4m @ 0.69g/t Au
-
Aircore drilling along the N extension of the Fortitude Shear corridor which remains untested by past drilling; and
-
Aircore drilling of the poorly tested southern extension of the Fortitude Shear at the Fortitude Far South prospect.

KILLALOE PROJECT (GOLD/NICKEL)
The Killaloe Project comprises 11 licences as summarised in Figure 4. Most previous gold exploration has been carried out on three licences: (E63/1018, E63/1199 and P63/1672) which is subject to a joint venture between Matsa and Cullen Resources Limited (MAT80%, CUL20%). The remaining licences are held 100% by Matsa except for E63/1655, which is subject to a joint venture between Matsa (85%) and Yilun Pty Ltd (15%). Exploration of the project is managed by Matsa.
S2 Resources Ltd’s (S2R) recent announcements of high grade gold at its Polar Bear project have highlighted a gold “corridor” defined by new gold discoveries at Baloo, Monsoon and Nanook within S2R’s Polar Bear project. ( S2R announcement to ASX 14[th] April 2016 ).
The corridor can be extended to the SE over a distance of ~20km into the Killaloe project area, thereby highlighting extensive soil gold anomalism and shallow gold intersections in previous drilling including 2m @ 6g/t Au in drill hole KRC023 at the Cashel prospect (Figure 4).
Past drilling for gold at Killaloe by Matsa and others has been shallow RAB drilling and very limited shallow RC drilling. (MAT announcement to ASX 5[th] July 2016).

Figure 4: Killaloe project, gold prospects on regional aeromagnetic image
Dipole-dipole array IP surveys were completed over the Duke and Shinboner prospects during the June quarter to test for the presence of sulphides at depth, as a potential vector for primary gold mineralisation beneath extensive soil gold anomalies and sporadic intersections in shallow drill holes.
Work Completed in the Current Quarter
Exploration carried out at Killaloe during the current quarter included the following:
-
Gradient array IP surveys at the Duke and Windy Hill prospects (Figure 6);
-
Dipole-dipole array IP surveys at the Cashel and Shinboner prospects for a total of 6 line kilometers;
-
Audio-frequency magnetotellurics (AMT) soundings were carried out as a Research and Development project using data collected during the gradient array IP surveys;
-
16 RC holes for 2,241m of drilling were completed at Duke, Windy Hill, Cashel and Shinboner; and
-
Assays of 567 composite RC samples for gold only.
Dipole-dipole IP surveys
These were carried out over the Cashel and Shinboner prospects. Survey parameters are described in Appendix 1 and survey lines are shown in Figure 5.
Shinboner
A single orientation line was completed parallel with the geological strike over a distance of 3.4 kms. Results clearly show three strong chargeability anomalies SB01 to SB03, with each of these coinciding in part, with moderate strength resistive zones. SB01-SB03 were interpreted to reflect zones of strongly developed disseminated sulphides (pyrite). The three targets are reasonably similar in amplitude and character which could be attributable to the presence of a stratabound chargeable unit located immediately adjacent to and sub-parallel with the survey line. Accordingly, RC drilling was carried out to test the strongest chargeable zone to determine the source.

Figure 5: Induced Polarisation Surveys and RC Drilling Duke and Windy Hill
Cashel
A single orientation line was completed over a distance of 1 km in a NE direction approximately at right angles to the geological strike. IP and resistivity data was strongly influenced by “EM effects” probably caused by the presence of strongly conductive carbonaceous and pyritic shale units at shallow depth. The survey did not define a disseminated sulphide type response.
Gradient Array (GAIP) IP Surveys
Two gradient array IP surveys were carried out over targets selected from the first pass dipole dipole IP surveys carried out during the June quarter at the Duke and Windy Hill prospects (Figure 6). AMT data is being retrieved from the gradient data measurements and the final data is expected to be received early in the next quarter.
A description of the GAIP survey parameters is presented in Appendix 1.
Duke IP03
The GAIP survey confirmed the chargeability and resistivity features at this target and was interpreted to indicate a SE trending 200m x 400m chargeable zone thereby confirming the IP anomaly. The orientation of this chargeable zone was used to design a fence of three RC drill holes as described below.
==> picture [596 x 56] intentionally omitted <==

Matsa Resources Limited
----- End of picture text -----
Windy Hill IPO2
The GAIP survey defined a complex chargeability feature bounded by a NE trending fault and partly coinciding with a well-defined soil gold anomaly but did not confirm the deeper IP anomaly that the GAIP survey was centred on. A fence of three RC drill holes was designed to test this chargeability anomaly.
AMT-IP trial survey
Trial audio-frequency magnetotellurics (AMT) – survey was carried out in conjunction with the GAIP surveys on the Windy Hill IP03 and Duke 02 dipole-dipole IP targets. The AMT survey was carried out as part of an R & D study making use of data which was not used in the past due to limitations in sensor technology and computing power.
The aim of the R&D project was to test and demonstrate the ability to glean AMT data from IP time series using Zonge receiving equipment and software. The AMT data derived from time series collected for a GAIP survey has the potential to provide resistivity information at depth for each survey line. Inversion modelling incorporating AMT data, extends the usual 2D nature of GAIP data at depth to allow a 3D visualisation of the structure. This has the potential to increase the effectiveness of this comparatively cost-effective survey technique.

RC Drilling
A total of 16 RC holes for 2,241m were drilled this quarter at Killaloe primarily to test new IP targets at Duke, Windy Hill and Shinboner, and to test depth extents of known mineralisation at Duke and Cashel prospects (Table 3, Figures 5 and 6).

Table 3: Killaloe 2016 RC Drill holes
Duke
RC drill holes 16KLRC006 to 16KLRC008 were completed over the Duke IP03 target and encountered predominantly serpentinised olivine orthocumulate komatiites together with minor spinifex textured komatiites and gabbro. Only trace amounts of sulphides were encountered at this target and in this case, fibrous minerals in the serpentinised komatiite appear to be the source of a non-metallic IP response and are interpreted to explain this moderate strength chargeability anomaly. There were no significantly elevated gold values in composite sample assays.
RC drill holes 16KLRC009 to 16KLRC011 were targeted on the down-dip extension of the gold mineralisation at Duke IP01. These holes also encountered serpentinised olivine orthocumulate komatiites and sheared talc-serpentinite rock. Weak gold anomalism associated with quartz veining was intersected in sheared komatiites and correspond with the down-dip extension of the gold mineralisation at this target. Anomalous gold intercepts are presented in Table 4 below.

Windy Hill
Drill holes 16KLRC012, 16KLRC013 and 16KLRC014, was completed over the Windy Hill IP02. They intersected predominantly mafic volcaniclastics and fine grained metasediments including siltstones and pyritic black shales. Blocky spinifex fragments are common in the volcaniclastics sections which suggests proximity to ultramafic source rocks. Pyrite disseminations and blebs were observed through most of the metasedimentary sequence and the presence of these sulphides adequately explains the strong IP anomaly at this target. The last 1m sample from

----- End of picture text -----
16KLRC014 which was terminated due to adverse ground conditions, returned the best gold result from this target of 1m @ 0.26 g/t Au from 84m. Further work is contemplated.
Drill holes 16KLRC015, 16KLRC020 & 16KLRC021 were completed over Windy Hill IP03. These drill holes intersected a similar sequence of rocks to those at Windy Hill IP02 which intersected strongly pyritic volcaniclastics and siltstones which are interpreted to be the source of the IP anomaly. No significant assays were returned from these holes.
Cashel
A single hole, 16KLRC016, was drilled to test the structural target beneath the gold lode at Cashel. This hole intersected several narrow quartz veins within the regolith profile followed by fine grained metasediments and volcaniclastics. No significant assays were returned.
Shinboner
Three RC holes, 16KLRC017 to 16KLRC019, were completed to test IP anomaly SB_IP03. The geology is similar to Windy Hill prospect and these holes encountered a sequence of mafic volcaniclastics and fine grained metasediments. Spinifex textured komatiitic basalt fragments are common in the volcaniclastics. The sequence is moderately to strongly pyritic and is interpreted to be the source of the IP anomaly at this target. Weakly anomalous gold values were intersected in hole 16KLRC018 and 16KLRC019 (Table 5).

MT DAY PROJECT (NICKEL)
The Mt Day nickel project is located 25km north of Maggie Hayes and Emily Anne nickel mines near Lake Johnstone (Figure 7).
Shallow drilling at Mt Day by previous explorers achieved nickel intercepts up to 1.51% Ni with strong supporting copper values up to 0.17% Cu in weathered ultramafics (MAT announcement to the ASX 31[st] May 2016) . These anomalous intercepts occur within a distinctive hook shaped high amplitude magnetic anomaly reflecting concealed komatiite lavas which may be an extension of the host rocks to the Emily Anne and Maggie Hayes deposits 25km to the south. This ultramafic belt is referred to as the Johnson Sandplain (JS) prospect. While significant past drilling has been carried out over the JS prospect, only two diamond holes intersected unweathered basement.
MLEM surveys were carried out during the June quarter, over two prospective komatiite targets where ground EM surveys had not previously been carried out. This led to discovery of a moderate EM conductor MDC01 associated with a discrete magnetic anomaly 4km east of the JS prospect. (MAT announcement to the ASX 31[st] May 2016) .
Exploration carried out during the September quarter:
-
RC drilling, a total of 7 drill holes were completed for a total of 1049m; and
-
Assays of 265 composite RC drill samples.
RC Drilling
The drilling program at Mt Day comprised 7 RC drill holes, for a total of 1049m, to test a number of nickel targets in the JS prospect. Two of these holes tested EM anomalies with the remainder testing for the presence of nickel sulphides in fresh komatiite beneath a nickel anomalous regolith zone, with previous intercepts of up to 1.5% Ni.

JS Prospect
Holes 16MDRC01 to 16MDRC06 were designed to test for primary nickel sulphide mineralisation in fresh rock beneath the nickel anomalous weathered zone defined by past RAB and aircore drilling at the JS prospect. Top of fresh rock is between 65m to 100m from surface.
With the exception of two diamond drill holes, most past drill holes, on this prospect did not reach the unweathered basement and the current RC drill holes were designed to provide bedrock information at depth below the strongly nickel-enriched weathered zone. Drilling on the JS prospect encountered dominantly olivine meso-cumulate komatiite, with lesser felsic pegmatites and granitic intrusions. Drilling is briefly described below. Drill holes 16MDRC02-16MDRC05 were drilled on the same section (Figure 7 and Figure 8).

16MDRC01 intersected olivine meso-cumulate komatiite cut by several felsic pegmatite intrusions, up to 8m wide. Assay results returned 44m of 0.5% Ni from 28m including 16m at 0.85%Ni from 32m within the nickel anomalous regolith zone above fresh olivine meso-cumulate containing maximum nickel values of ~ 0.1% Ni.
16MDRC02 is located close to past drill hole JSA179 which intersected 3m of 1% Ni from 51m, in weathered ultramafic rocks. 16MDRC02 confirmed this nickel enrichment in the weathered zone, with assays returning 20m 0.28% Ni and 0.016% Cu from 48m, but did not detect any significant mineralisation in underlying fresh rock.
16MDRC03 is a deeper drill hole at the same location as past JSA180 which returned an intercept of 15m of 0.77% Ni & 0.12% Cu from 15m, including 3m of 1.5% Ni and 0.17% Cu from 21m. 16MDRC03 intersected 2 zones of strongly nickel anomalous regolith with a best intercept of 24m of 0.46% Ni from 12m. No significant mineralisation was identified in unweathered rocks
16MDRC04 (198m) intersected nickel enriched regolith with a best intercept of 8m of 0.37% Ni from 72m. Olivine meso-cumulates and lesser felsic pegmatites passed into a suite of felsic pegmatite and gabbro a depth of 126m and granodiorite from 182 to the bottom of the drill hole at 198m. A 6m zone of matrix sulphides, up to 5% by volume, was observed in the olivine meso-cumulate from 101m. Selected rock chips from this interval will be sent for petrographic analysis to determine if the sulphides seen in this section are of magmatic origin and potentially increasing the prospectivity of the JS target for primary nickel sulphide mineralisation.
16MDRC05 encountered comparatively deep weathering to 118m down hole. Fresh rock is mostly gabbro with minor BIF, felsic pegmatite and komatiite. Two narrow zones of weak nickel enrichment up to 0.11% Ni in the weathered profile, occur between 32m to 52m.
16MDRC06 was located in the sparsely drilled southern extremity of the hook shaped JS komatiite trend where Matsa’s recent EM survey detected a moderate “stratigraphic” conductive zone. This drill hole intersected variably feldspathic gabbro. No sulphides were noted and the source of the conductive zone was not resolved.
The last hole in the Mt Day program, 16MDRC07 was drilled to test the MDC01 target a moderate strength EM conductor detected by Matsa’s ground EM survey carried out during the June quarter. MDC01 is located adjacent to a discrete magnetic anomaly which was interpreted to represent a faulted offshoot of the main western komatiite trend at the JS prospect. This interpreted komatiite location had not been previously tested by drilling. 16MDRC07 intersected granitic rocks with trace disseminated pyrite. A downhole EM survey is planned on 16MDRC07 to test for the presence of an off-hole conductor in the vicinity.
MT WELD PROJECT (GOLD)
Mt Weld gold project is located 60km south of Laverton, 12km SE of AngloGold Ashanti’s Sunrise Dam gold mine and 11km NE of Saracen Minerals Ltd (ASX:SAR) Red October gold mine. The project is immediately adjacent to Matsa’s newly acquired Lake Carey gold project and includes areas with potentially significant shallow drill intercepts at Wilga South (Figure 9).

Figure 9: Mt Weld Project Location of RC drilling on aeromagnetic image
The current exploration target is gold mineralisation associated with a ~2km long gold anomaly at Wilga South, defined by historic RAB and aircore drilling along the sheared contact between intermediate and mafic volcanics in the Laverton Tectonic Zone.
Basement rocks have been weathered to depths greater than 30m and weathered basement is overlain in places by transported sediments associated with the Lake Carey drainage system. Strong linear magnetic features in aeromagnetic data are evident and these are interpreted to define major structural and stratigraphic boundaries in the archaean basement. Basement in the area of interest, is made up mostly of basalts with lesser andesitic volcanics, felsic porphyry and dolerite.
Exploration during the September Quarter
A total of 5 RC drill holes, for 1037m, was completed at the Wilga South prospect in the Mt Weld project during this quarter (Table 8). These holes were designed to test the down-dip continuity of the gold mineralisation defined from historic drilling on this target. Rocks encountered from these holes are mainly basalts and dolerite with lesser andesitic volcanics and metasediments. Mineralised zones are associated with weakly sulphidic narrow quartz veins in foliated basalt and dolerite.

Assays from the current programme have shown the steeply dipping gold mineralised zone to extend at depth with a best intercept of 4m @ 0.94 g/t Au from 188m in 16MTWRC04. Further work on this prospect is being considered as part of a broader programme including Matsa’s newly acquired Lake Carey gold project.
SYMONS HILL PROJECT (NICKEL)
E69/3070 of 96km[2] is located within the Fraser Range Tectonic zone, 6kms SSW of Independence Group Ltd’s (ASX:IGO) Nova nickel mine. There is currently significant M&A activity in the locality and accordingly the Symons Hill project is recognised as a valuable area for any accumulator of tenements in this highly prospective locality.
Collaborative Research Project with CSIRO
A collaborative research project jointly funded by Matsa and the Commonwealth Scientific and Industrial Organisation (CSIRO), was set up to review the very large exploration database in this area of deep weathering and variable depths of transported cover. The project is intended to integrate geochemical data, drilling data and airborne and ground geophysical data to provide a more complete understanding of geological processes in this highly prospective belt, to determine improved exploration techniques for Nova style Ni-Cu massive sulphide deposits and to define new exploration targets.
The following activities were carried out during the quarter:
-
A subset of drill cuttings and core from Matsa’s diamond RC drill holes were selected for re-logging and sampling. A total of 90 drill holes were re-logged; and
-
Field survey and collection of samples for geochemical and petrographic analysis. Geochemical sampling comprised collection of regolith and basement rock samples from selected locations and drill holes to characterize the mineralogy and geochemistry of the stratigraphic units of the cover as well as the basement.

The research team have now collected sufficient samples and observations and a report is expected to be completed during the December 2016 quarter.
THAILAND
Matsa’s Thailand projects cover 909km[2] within the Loei–Ko Chang fold belt which contains important mineral deposits including the >5MOz Chatree gold mine of Kingsgate Consolidated Ltd (ASX:KCL). The Loei-Ko Chang arc is an arcuate palaeo – island arc terrane which is more than 600km long and oriented approximately north–south. This terrane extends from Ko Chang Island in the south to Loei in the north of Thailand and beyond into Laos.
During the quarter exploration work comprised diamond drilling of Matsa’s recently discovered Chang 1 copper project. Whilst works at Siam 1 have been temporarily suspended, works at Chang 1 have progressed smoothly without interruption. Community leaders and regional authorities are keen to see Matsa develop opportunities around the Chang 1 region and have demonstrated significant support and enthusiasm towards Matsa. Recent disruptive events relating to Thailand gold mining activities which have impacted the Chatree gold mine have had little or no adverse impact to Matsa’s ongoing exploration programme for copper. It is important to recognise that the negativity surrounding the Chatree gold mine is limited to gold mining activities only and the Thai government departments are clear that copper and base metal exploration and mining remain unaffected.
PAISALI PROJECT (BASE METALS)
Multi-element assays prior to the current quarter, identified a soil copper anomaly over an area of ~1km x 1.8km with copper values up to 0.11% Cu. Geochemical zoning is evident with a central zone of highly anomalous Cu with supporting Ag and Ni values, surrounded by anomalous Pb, Zn etc. values on the periphery. (MAT announcements to ASX 27[th] April 2016 and 29[th] April 2016).
Dipole-dipole IP surveying during the previous quarter at Chang 1 returned moderate IP responses up to 12mV/V over three central lines (742800N, 742600N and 742400N). The IP anomalies in the central lines partly coincide with the soil copper anomaly and were interpreted to reflect disseminated sulphides in fresh underlying rocks. The soil copper and IP anomalies are located within a large complex magnetic anomaly containing scattered diorite rubble. This association is taken as strong support for intrusion related hydrothermal copper sulphide mineralisation (Figures 12, 13 and 14).
During the quarter, exploration comprised:
-
Diamond drilling of 4 drill holes for a total of 766m; and
-
Ground magnetic surveys over Chang 1 for a total of 11 lines totaling 14.2 line km.
Diamond Drilling
Activity for the quarter comprised 4 diamond drill holes for 766m at Chang 1. Drilling progress was comparatively slow with productivity hampered by the wet season.

Figure 12: Chang 1 Oblique view of drilling on IP sections and geochemistry. (Red >200ppm Cu, Pink > 400ppm Cu)
Drilling to date has targeted IP chargeable anomalies within the broader 2km x 1km >200ppm Cu soil geochemical target area. Drilling has intersected coarse grained diorite with weak potassic and propylitic alteration and up to 1% fine to coarse grained interstitial and euhedral disseminated chalcopyrite. Pyrite and chalcopyrite are also present in veining.
Results have been received for only 2 of the 4 drill holes completed to date. Both have returned encouraging elevated copper values. Trace disseminated chalcopyrite has been intersected in all drill holes drilled to date over significant widths in excess of 100m, e.g. 16SCDD03. Best results to date include 2m @ 0.26 % Cu in hole 16SCDD003. A summary of received results is presented in Table 11.
A further two holes are planned to be drilled in the upcoming quarter.

On the significance of the Chang 1 discovery, Matsa Executive Chairman Paul Poli made the following comments: “It was pleasing that diamond drilling at the soil anomaly discovered by Matsa has produced such wide intersections of copper over a large area. The area of copper mineralisation is large and this could be interpreted that the mineralisation seen to date at Chang 1 is significant with potential for higher grade areas or shoots nearby. The extensive copper mineralisation is viewed as a geologically significant occurrence. The fact that chalcopyrite is being seen in every hole drilled to date is highly encouraging and with further work in the area it is hoped that an economic ore body can be defined”.
Work is being accelerated in the other currently untested areas with further drilling planned in the near future.

Ground Magnetics
A ground magnetic survey has commenced at the Chang 1 Prospect. The ground magnetic survey is being undertaken over the area of anomalous Cu geochemistry and IP chargeability responses. To date 11 line (14.2 line km) of data has been collected on 100m line spacing with readings taken every 10m. Weather delays have interfered with the data acquisition.
SIAM PROJECT (COPPER)
Matsa completed an induced polarisation (IP) ground electrical survey at Siam 1 in December 2015. The survey comprised 6 lines at Siam 1 West and 7 at Siam 1 East. (MAT announcements to the ASX 29[th] October 2015 and 29[th] January

2016) . The Siam 1 prospect was prioritised for IP surveys because of Matsa’s discovery there of widespread boulders containing visible native copper and the previously announced discovery of supergene chalcocite containing very high copper and silver grades of up to 54.6% Cu and 148 g/t Ag .
Work carried out during the quarter comprised collection of 190 Soil auger samples focused within the extensive Siam 2 soil anomaly. Assays are awaited.

Core and non core drill samples (Fortitude, Mt Weld, Killaloe) are assayed for gold only using 30g Fire Assay method as being a total assay (ALS Method Code Au-AA25) Non core samples from Mt Day Nickel project were assayed for a 33 element suite based on a 4 acid digest. This too is seen as a total digest method. (ALS code ME ICP61 4 acid ICP AES, element suite MEICP61 33 Element AssaySuite Ag ppm Cr ppm Mo ppm Sr ppm Li ppm Al % Cu ppm Na % Th ppm As ppm Fe % Ni ppm Ti % Ba ppm Ga ppm P ppm Tl ppm Be ppm K % Pb ppm U ppm Bi ppm La ppm S % V ppm Ca % Mg % Sb ppm W ppm Co ppm Mn ppm Sc ppm Zn ppm QA QC for Fortitude is in line with industry standard practice with one in 20 samples being a standard sample of known gold grade. Quality of core and non core samples from Mt Weld, Killaloe, Mt Day, Chang1 and Siam 1 is assessed on insprction of Laboratory QA QC data |
| Verification of sampling and assaying The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. |
At Fortitude, part of the purpose behind core drilling is to verify historic drilling data At mt Day, where the target is enriched Ni values, verification was carried out on 2 drill holes by twinning these. Data is maintained in Datashed which is a database system which is maintained inhouse Logging data is entered in the field to minimize transcription errors, assaydata are loaded electronically |
| Location of data points 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. |
All drill holes are set up by handheld GPS to 3m accuracy. Diamond Drill holes are resurveyed on completion using a hired DGPS sysemt. Drilling under the Fortitude, Killaloe, Mt Day and Mt Weld project is all located using the MGA GDA94 UTM ocation Zone 51. Drilling in Thailand is located using the Indian Thailand 1975 dataum zone 47 |
