ASX Announcement

EXPLORATION UPDATE - SWEDEN

Key points

  • First drilling of winter campaign intersects narrow zone of high grade zinc mineralization 170 metres down plunge from last intercept at Bjurtraskgruvan VMS deposit
  • XRF readings indicate massive sulphides grade 10-44% zinc
  • Rig moved to new prospect at Granbergs (Holmtjarn area) while assays awaited

S2 Resources Ltd ("S2" or the "Company") provides the following update regarding its winter drilling program at its 100% owned Skellefte project in Sweden, where it is systematically reconnaissance drilling a number of targets identified and prioritized during the summer field season.

Bjurtraskgruvan VMS deposit

In the first drilling of S2's Swedish winter drilling campaign, diamond core hole SBJK170008 confirmed the continuation of VMS mineralization 170 metres down plunge from its previous drilling at the Bjurtraskgruvan deposit, undertaken at end of last winter's drilling program.

Hole SBJK170008 intersected a narrow (1 metre) zone of sphalerite (zinc sulphide) dominant massive sulphide mineralization (see Figure 1). Assay results will not be available until late January, but spot XRF readings taken across the massive sulphides in this zone range from 10.7% to 44.6% zinc. It is not yet known if this is accompanied by any precious metals.

This was the second hole of this program, with the first (hole SBJK170007) having lifted and missed the EM conductor.

The new intercept confirms the presence of VMS style mineralization over a plunge extent of 600 metres at Bjurtraskgruvan (see Figure 2).

Although the deposit remains open down plunge and is not fully delineated, the thickness of the mineralization is not considered sufficient to warrant diversion of the rig at this time from the many other targets scheduled for reconnaissance drilling over the next few months. Consequently, the rig has moved and begun drilling the new Granbergs target at Holmtjarn.

Granbergs target

The first of three reconnaissance diamond core holes planned as an initial test of the Granbergs target is underway.

The Granbergs target was identified as a result of induced polarization (IP) geophysics and base of till (BOT) sampling undertaken in the Holmtjarn area over the summer. It is located to the south of the main Holmtjarn trend (refer to ASX presentations of 17th October and 21st November 2017) which is along strike from a gold-rich VMS deposit mined by Boliden in the 1950's.

The target comprises a 500 metre long IP chargeability anomaly coinciding with strong lead-silvercopper-gold-arsenic-antimony anomalism in BOT sampling (see Figure 3).

Figure 3. Summary plan of the Granbergs prospect, Holmtjarn.

The BOT anomaly comprises a coherent cluster of strongly anomalous samples over a 350 x 100 metre area, with peak samples being 1.25% lead, 88g/t silver, 946ppm copper, 89ppb gold and >10000ppm arsenic (see Figure 4).

The coincident IP and BOT anomaly at Granbergs is located approximately 400 metres northwest of two diamond core holes drilled by S2 in early 2017 (holes SHOL170005 and SHOL170006). These holes were drilled before the IP and BOT data was collected, but nonetheless intersected substantial widths ofsulphide-bearing rhyolite breccias with broad zones of anomalous copper and gold with peak values of 0.6g/t gold and 0.66% copper (refer to ASX announcement of 8 th May 2017), located 400 metres along strike of the new Granbergs target.

Holes GRB91008 and GRB91009 are old holes drilled in a southeasterly direction by Boliden approximately 200 metres south of the new Granbergs target.

Criteria JORC Code explanation Commentary
Sampling techniques Nature and quality of sampling (e.g. cut channels,random chips, or specific specialised industrystandard measurement tools appropriate to theminerals under investigation, such as down holegamma sondes, or handheld XRF instruments, etc).These examples should not be taken as limiting thebroad meaning of sampling. Drilling is undertaken by Arctic Drilling or Oy Kati AB of KalajokiFinland drilling NQ2 rod size with a DDH size of 75.7mm andcore size of 50.7mm. NQ2 core samples are logged and markedup by S2 personnel. Unbiased core sample intervals were cut inhalf by diamond saw with half core sent for analysis at ALSLaboratories.All rock grab and rock float samples are collected from outcropby S2 personnel and marked into sample books and arepresentative portion of the sample retained. All areforwarded for analyses by ALS Laboratories.
Include reference to measures taken to ensuresample representivity and the appropriatecalibration of any measurement tools or systemsused Sampling and QAQC procedures are carried out using S2protocols as per industry best practice.
Aspects of the determination of mineralisationthat are Material to the Public Report. In caseswhere 'industry standard' work has been done thiswould be relatively simple (e.g. 'reverse circulationdrilling was used to obtain 1 m samples fromwhich 3 kg was pulverised to produce a 30 gcharge for fire assay'). In other cases moreexplanation may be required, such as where thereis coarse gold that has inherent samplingproblems. Unusual commodities or mineralisationtypes (e.g. submarine nodules) may warrantdisclosure of detailed information Diamond drilling was used to obtain core samples that havebeen cut and sampled on intervals that are determined bylithology and mineralisation.The drill core samples are sent to ALS Laboratories for analysesfor gold and base metals. Drill core is sampled at S2's facilitiesin Mala, Sweden.
Drilling techniques Drill type (e.g. core, reverse circulation, open-holehammer, rotary air blast, auger, Bangka, sonic,etc) and details (e.g. core diameter, triple orstandard tube, depth of diamond tails, facesampling bit or other type, whether core isoriented and if so, by what method, etc). Diamond drilling with NQ2 wireline bit producing a 50.7mmdiameter core.
Drill samplerecovery Method of recording and assessing core and chipsample recoveries and results assessed DiamondDrillcorerecoveriesarevisuallyestimatedqualitatively on a metre basis and are recorded in the database.
Measures taken to maximise sample recovery andensure representative nature of the samples Sample quality is qualitatively logged on a metre basis,recording sample condition.
Whether a relationship exists between samplerecovery and grade and whether sample bias mayhave occurred due to preferential loss/gain offine/coarse material. No relationship has been seen to exist
Logging Whether core and chip samples have beengeologically and geotechnically logged to a level ofdetail to support appropriate Mineral Resourceestimation, mining studies and metallurgicalstudies. The logging uses a standard legend developed by S2 which issuitable for wireframing. Exploration holes are notgeotechnically logged but resource holes are.
Whether logging is qualitative or quantitative innature. Core (or costean, channel, etc)photography. All core has been photographed both dry and wet. Geologicallogging of the diamond drill holes is onto physical log sheetsfollowed by importing into S2's central database

All samples were forwarded to ALSMinerals Ojebyn, Sweden Laboratory where they are to becrushed with >70% <2mm (code CRU-31), split by riffle splitter(code SPL-21), and pulverised 1000grm to 85% <75 um (codePUL-32). Crushers and pulverizers are washed with QAQC testsundertaken (codes CRU-QC, PUL-QC). The prepared samples areforwarded to ALS Minerals Loughrea, Ireland, for analysis.
Quality control procedures adopted for all subsampling stages to maximise representivity ofsamples. Full QAQC system in place to determine accuracy and precisionof assays
Measures taken to ensure that the sampling isrepresentative of the in situ material collected,including for instance results for fieldduplicate/second-half sampling. For DDH's non biased core cutting through using an orientationline marked on core and cut to the line
Whether sample sizes are appropriate to the grainsize of the material being sampled. Samples of appropriate size
Quality of assay dataand laboratory tests The nature, quality and appropriateness of theassaying and laboratory procedures used andwhether the technique is considered partial ortotal. All samples were analysed by ALS Minerals Loughrea, Ireland.Samples analysed for gold undergo a 50g fire assay with AA finish(code Au-AA26). Samples analysed for Ag, As, Bi, Ca, Cd, Cu, Fe,Hg, Mg, Mn, Mo, Ni, P, Pb, S, Sb, Tl & Zn undergo an oxidisingdigestion with ICP-AES Finish (code ME-ICPORE).
For geophysical tools, spectrometers, handheldXRF instruments, etc, the parameters used indetermining the analysis including instrumentmake and model, reading times, calibrationsfactors applied and their derivation, etc. No geophysical tools were used to determine any elementconcentrations.
Nature of quality control procedures adopted (e.g.standards, blanks, duplicates, external laboratorychecks) and whether acceptable levels of accuracy(i.e. lack of bias) and precision have beenestablished. Full QAQC system in place including Certified Standards andblanks of appropriate matrix and levels
Verification ofsampling andassaying The verification of significant intersections byeither independent or alternative companypersonnel. Andy Thompson, GM Fenno-Scandia has personally inspected alldrill cores and rock samples.
The use of twinned holes. No twin holes have been drilled on the project to date.

Criteria JORC Code explanation Commentary
Quality and adequacy of topographic control. Excellent quality topographic maps produced by the SwedishAuthorities - Landmateriat
Data spacing anddistribution Data spacing for reporting of Exploration Results. Drill holes are exploratory at this stage and drilled to testgeochemical and geophysical target. No set spacing of drillholesat this stage.
Whether the data spacing and distribution issufficient to establish the degree of geological andgrade continuity appropriate for the MineralResource and Ore Reserve estimation procedure(s)and classifications applied. Data spacing and distribution is not sufficient at this stage toallow the estimation of mineral resources.
Whether sample compositing has been applied. No sample compositing has been applied
Orientation of datain relation togeological structure Whether the orientation of sampling achievesunbiased sampling of possible structures and theextent to which this is known, considering thedeposit type. Drillhole orientation is designed to test geophysical targets andis not necessarily drilled perpendicular to the orientation of theintersected mineralisation.
If the relationship between the drilling orientationand the orientation of key mineralised structures isconsidered to have introduced a sampling bias,this should be assessed and reported if material. The drilling at this stage is preliminary and exploratory. It is notpossible to assess if any sample bias has occurred due to holeorientation at this stage.
Sample security The measures taken to ensure sample security. Chain of custody is managed by S2 personnel. Drill core isvisually checked at the drill rig and then transported to S2'slogging and cutting facilities by S2 personnel for logging, cuttingand sampling. Bagged samplesaretransferred to ALSLaboratories in Malå, Sweden by S2 personnel.
Audits or reviews The results of any audits or reviews of samplingtechniques and data. No audits or reviews have been conducted at this stage.

SECTION 2 REPORTING OF EXPLORATION RESULTS

Criteria JORC Code explanation Commentary
Mineral tenementand land tenurestatus Type, reference name/number, location andownership including agreements or material issueswith third parties such as joint ventures,partnerships, overriding royalties, native titleinterests, historical sites, wilderness or nationalpark and environmental settings. The Bjurtraskgruvan prospect is located within the Vargfors 401Exploration Licence.The Holmtjarn targets are located on the Holmtjarn 401 Licence.The exploration licences are 100% owned by S2 Sverige AB, aSwedish registered 100% owned subsidiary of S2
The security of the tenure held at the time ofreporting along with any known impediments toobtaining a licence to operate in the area. All of the Exploration Licences are in good standing and noknown impediments exist on the tenements being activelyexplored.
Exploration done byother parties Acknowledgment and appraisal of exploration byother parties. The Bjurtraskgruvan prospect was drilled, trenched andmapped in 1944 and 1979-80. Drilling was undertaken by theSwedish Geological Survey (SGU) for a total of 481m in 1944and 1250m in 1979-80. The 1944 data was largely twinned bythe later drilling and also more comprehensively sampled.The historical geological mapping has been georeferenced inrelation to the drillhole collars and also correlates well with themodelled moving loop ground TEM plate. Drillhole collars havebeen located and surveyed by S2 personnel. All available publicdomain historic reports and logs at the SGU in Mala have beenreviewed and collated.
Geology Deposit type, geological setting and style ofmineralisation. The area occupies the central portion of the Skellefte Belt, aproductive base and precious metal mining district dominatedby bimodal volcanics, primarily felsic in composition.The mineralisation style is structurally remobilised volcanogenicmassive sulphide style mineralisation within greenschist grademetamorphic rocks.

Drill holeInformation A summary of all information material to theunderstanding of the exploration results includinga tabulation of the following information for allMaterial drill holes:easting and northing of the drill holecollarelevation or RL (Reduced Level –elevation above sea level in metres) ofthe drill hole collardip and azimuth of the holedown hole length and interceptiondepthhole length. Refer to Annexure 1 above
Data aggregationmethods In reporting Exploration Results, weightingaveraging techniques, maximum and/or minimumgrade truncations (e.g. cutting of high grades) andcut-off grades are usually Material and should bestated. All reported intersections of drilling undertaken by S2 have beenlength weighted and density weighted.A nominal 1% Zn or 0.5% Cu lower cut-off is used for diamonddrill intersections (unless otherwise stated in polymetallicintersections).
Where aggregate intercepts incorporate shortlengths of high grade results and longer lengths oflow grade results, the procedure used for suchaggregation should be stated and some typicalexamples of such aggregations should be shown indetail. High grade intervals internal to broader zones of mineralisationare reported as included intervals.
The assumptions used for any reporting of metalequivalent values should be clearly stated. None used.
Relationshipbetweenmineralisationwidths and interceptlengths These relationships are particularly important inthe reporting of Exploration Results.If the geometry of the mineralisation with respectto the drill hole angle is known, its nature shouldbe reported.If it is not known and only the down hole lengthsare reported, there should be a clear statement tothis effect (e.g. 'down hole length, true width notknown'). The trend of mineralisation at the targets/prospects described isnot known at present but core angles indicate thatmineralisation is approximately true width.Refer to Annexure 1 and Figures in body of text.
Diagram Appropriate maps and sections (with scales) andtabulations of intercepts should be included forany significant discovery being reported Theseshould include, but not be limited to a plan view ofdrill hole collar locations and appropriate sectionalviews. Refer to Figures in body of text.
Balanced reporting Where comprehensive reporting of all ExplorationResults is not practicable, representative reportingof both low and high grades and/or widths shouldbe practiced to avoid misleading reporting ofExploration Results. All results considered significant are reported.
Other substantiveexploration data Other exploration data, if meaningful andmaterial, should be reported including (but notlimited to): geological observations; geophysicalsurvey results; geochemical survey results; bulksamples – size and method of treatment;metallurgical test results; bulk density,groundwater, geotechnical and rockcharacteristics; potential deleterious orcontaminating substances. The area has numerous VTEM anomalies generated from a 2015VTEM survey. Most anomalies being drilled have been groundchecked using moving loop EM to confirm anomalism andenable modelling of specific drill targets. Base of till sampling isalso undertaken for interface geochemical information. At theBjurtraskgruvan prospect, rock chips have been taken fromoutcropping gossans. Historic data from the SGU has beencompiled and modelled in 3D. Moving loop EM has confirmedthe VTEM anomaly as shown in the body of the text.
