SKELLEFTE PROJECT UPDATE
Key points
-
Drilling at the first of ten targets (Svansele 403-3) intersects minor stringer and disseminated pyrite-pyrrhotite-sphalerite mineralisation
-
Drilling started at the second target, Svansele 403-2
-
Numerous EM conductors in new (second) VTEM survey
-
Ground-based EM and geochemical sampling of VTEM conductors ongoing
-
One of these new VTEM conductors coincides with a copper-zinc sulphide outcrop at the Bjurtraskgruvan prospect
S2 Resources Ltd (“S2” or the “Company”) advises that the first of ten targets designated for testing during the northern winter diamond drill campaign has been tested. Drilling intersected a minor zone of stringer and disseminated sulphides, for which assays are awaited but are expected to be low grade. Numerous new anomalies have also been identified in the second VTEM survey. One of these anomalies coincides with an outcropping copper-zinc bearing sulphides.
Minor sulphides intersected at Svansele 403-3 target
The first target to be drilled as part of the planned five month drilling campaign, known as Svansele 403-3, comprises a subtle VTEM conductor which resolved itself into two separate conductors following a more detailed ground-based moving loop EM (MLEM) survey. Two holes, SSVA 1701 and 1702, were drilled to test these, and subsequent down hole EM (DHEM) in the first hole identified a subtle offhole conductor. Hole SSVA1703, drilled to test this, intersected a 2.4 metre thick zone of mainly disseminated with some stringer sulphide mineralization from 196.4 metres downhole, comprising pyrite, pyrrhotite and some sphalerite, within a felsic volcanic sequence (see Figures 1 and 2, and Annexure 1). Although it will take several weeks to receive assays for this intersection, visually it appears only weakly mineralized. It is, however, encouraging to intersect mineralization within appropriate host rocks at the first target drilled in the campaign.
This is the first target of three in a cluster, with the other two being Svansele 403-2 (see ASX announcement of 28[th] October 2016) and Svansele 403-1, which was renamed as the Svan Vit prospect

following drilling early in 2016 (see ASX announcements of 21[st] April 2016 and 9[th] May 2016) (see Figure 3). Drilling of these and other targets will continue over the next 5 months, with priorities being determined primarily by ground access conditions.

The drill rig has since moved to the next target, which is Svansele 403-2, located approximately 400 metres to the southwest of Svansele 403-3, between the latter and the Svan Vit prospect (see Figure 3).
Ground-based MLEM and base of till (BOT) geochemical sampling is also being systematically extended over additional targets.
Numerous strong conductors identified in new VTEM survey
Final imagery of the recent VTEM survey has been received, highlighting numerous new anomalies (see Figures 4 to 7). These will be followed up with ground-based MLEM and BOT sampling where appropriate over the next several months.
The new survey is only the second VTEM survey ever flown in this major base and precious metal mining district, in which S2 is the dominant ground holder. It follows and partially adjoins the first ever VTEM survey, which was also flown by S2 in 2015.
The new survey was flown in three parts to cover newly acquired ground. One of these areas was over new ground acquired adjacent to the original survey area and has been merged with it (see Figures 4 and 5), and the other two areas are geographically separate (see Figures 6 and 7).

One of the many EM anomalies (Vargfors 401-4) identified in the new VTEM survey coincides with a zone of outcropping copper-zinc sulphide mineralization at a prospect known as Bjurtraskgruvan, located 2 kilometres west of the Svan Vit prospect (see Figures 5 and 8). This area was subject to limited drilling by government agencies in the 1940’s and the 1980’s but has not had any modern exploration or drilling. Ten rockchip and float samples collected from this outcrop are all enriched in either zinc or copper-gold-silver, as follows:
-
Three samples grade 2.68%-6.47% zinc , with negligible copper, gold or silver
-
Seven samples grade 4.71%-13.25% copper , 0.26g/t-6.74g/t gold and 30g/t-95g/t silver , with negligible zinc
Ground based MLEM will commence shortly and, subject to positive follow up results and obtaining appropriate government and access approvals, this will be included in the winter diamond drilling program.

SECTION 1 SAMPLING TECHNIQUES AND DATA
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. |
The EM geophysical target at Svansele 403 target 3 was tested by diamond drilling with a planned three DDH program on this target. Drilling has been undertaken by Oy Kati AB of Kalajoki Finland drilling NQ2 rod size with a DDH size of 75.7mm and core size of 50.7mm. NQ2 core samples were logged, marked by S2 staff, Unbiased core sample intervals were cut in half by diamond saw.Half core from DDH’s SSVA17001 has been sent for analyses by ALS Laboratories, whilst SSVA17002 & SSVA17003 are presently being sampled. All rock grab and rock float samples are collected from outcrop by S2 staff and consultants marked into sample books and a representative portion of the sample retained. All are forwarded for analyses by ALS Laboratories. |

Sampling and QAQC procedures are carried out using S2 Sverige AB’s protocols as per industry best practice. |
| Criteria | JORC Code explanation | Commentary |
| Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information |
Diamond drilling was used to obtain core samples that have been cut and sampled on intervals that are determined by lithology and mineralisation. The drill core samples from SSVA170001 have been sent to ALS Laboratories for analyses for gold and base metals. SSVA170002 & SSVA170003 drill core is presently being sampled at S2 Sverige AB’s facilities in Mala, Sweden. |

SECTION 2 REPORTING OF EXPLORATION RESULTS
| 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 Svansele 403 -3 VTEM target is located within the Svansele nr 403 Exploration Licence (Diary number 2015:39)_,_which is 100% owned by Sakumpu Exploration filial (at present under transfer to S2 Sverige AB) both companies wholly owned subsidiary of S2 Resources Ltd. |
| 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 Svansele nr 403 Exploration Licence is in good standing and no known impediments existon the tenement being actively explored. |
|
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
DDH’s SSVA170001 & SAVA170003 are drilled in an old sand quarry owned by Boliden Mineral AB for use as fill in the mines, a historic drill collar was noticed in the vicinity but no knowledge or public domain information is available on the DDH. |
| Geology | Deposit type, geological setting and style of mineralisation. |
The Svansele project is situated within the central portion of the Skellefte Belt, a volcanogenic massive sulphide camp dominated by bimodal volcanics, primarily felsic in composition. The mineralisation style appears from the drill holes typical volcanogenic massive sulphide style mineralisation with greenschist grade metamorphism |
| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole length. |

| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. |
NA |
| Criteria | JORC Code explanation | Commentary |
| Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. |
NA | |
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
None used | |
| 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 (e.g. ‘down hole length, true width not known’). |
The trend of mineralisation at Svansele 403 -3 is not known at present but core angles indicate that mineralisation is approximately true width. Borehole EM modelled in Maxwell indicates a shallow dipping plate east of DDH SSVA170001 – awaiting results from BHEM on DDH SSVA170003 Refer to Annexure 1 and Figures in body of text. |
| Diagram | 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. |
Refer to Figures in body of text. |
| 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. |
Mineralisation is determined visually then sampled with results awaited |
| 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. |
The Svansele 403 -3 was a one of a number of priority VTEM targets generated during Sakumpu Exploration’s 2015 VTEM survey. This target was ground checked by moving loop ground TEM which gave an anomaly that when modelled showed two separate plates. Base of Till sampling returned a peak geochemical response adjacent to the northern of the geophysical anomalies. Access and snow conditions dictated that this was the first target drill tested in this winters’ testing. DDH’s SSVA17001 & SSVA17003 were successfully probed by downhole EM by Geovisor of Rovaniemi, Finland. Results of the BHEM from SSVA17001 are detailed in the body of the text. |
| Further work | The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive |
Results of the BHEM on SSVA170003 will determine if any additional work is justified on this target. |
