FURTHER ASSAY RESULTS FROM DRILLING AT THE AARNIVALKEA GOLD PROSPECT IN FINLAND
Key Points
-
Assays received for the upper part of diamond hole FAVD0066 above previously reported intercepts of 0.64 metres at 7.5g/t gold and 6.79 metres at 1.2g/t gold at the Aarnivalkea (Aarni’) gold prospect
-
New assays define an additional intercept of 18.6 metres at 1.1g/t gold, including 1.8 metres at 7.60g/t gold, within a broad lower grade zone of ~90 metres at 0.4g/t gold
-
Assays are awaited for the remainder of this hole (FAVD0066) and FAVD065, and for the entirety of holes FAVD0067 to FAVD0072 at Aarni’
-
Hole FAVD0073 is underway, after which, the drill rig will relocate to test the Ruopas Isovaara nickel-copper-PGE target
S2 Resources Ltd (“S2” or the “Company”) has received gold assay results for the upper 290 metres of diamond hole FAVD0066 drilled at the Company’s 100% owned Aarnivalkea prospect in the Central Lapland Greenstone Belt (“CLGB”) in northern Finland. The best interval of mineralisation is 18.6 metres at 1.1g/t gold from 228.0 metres, including 1.8 metres at 7.60g/t gold from 244.8 metres, within a broader lower grade interval of ~90 metres at 0.4g/t gold from 172 metres (see Figure 1). This zone is in the hangingwall of the previously reported intervals from hole FAVD0066 (refer to S2’s ASX announcement dated 9[th] August 2021) which include:
-
0.64 metres at 7.5g/t gold from 314.2 metres, and
-
6.79 metres at 1.2g/t gold from 330.5 metres, including 0.89 metres at 5.2g/t gold from 335.5 metres
The broad mineralised zone now identified in hole FAVD0066 is associated with variably sheared and altered dacitic and andesitic porphyritic intrusives.
Commenting on the drill results, S2’s Chief Executive Officer Matthew Keane said, “S2 is highly encouraged by the broad zone of gold anomalism in hole FAVD0066. There is clearly a lot of gold in the Aarni’ system. Once we have received further assays from this program of very broad spaced step-out drilling, we will look to vector in on potential zones of higher-grade gold concentration. In the meantime, Ruopas Isovaara provides us with an exciting nickel-copper-PGE target, with drilling to commence imminently”.

Hole FAVD0066 is located 265 metres north hole FAVD0062, which intercepted 6.8 metres at 11.8g/t gold from 223.0 metres and 300 metres south of hole FAVD0064, which intercepted 20.4 metres at 4.0g/t gold from 193.1 metres (see S2 ASX announcements dated 8[th] December 2020 and 4[th] January 2021). The deeper zone of gold mineralisation at Aarni’ is greater than 700 metres in strike, with all assayed holes drilled below 110 metres containing significant mineralisation. The initial 1,100 metre target zone for the current broad spaced scout program has been extended by a further 200 metres to the south, after a favourable drill platform was identified within a generally hard to access swampy area. As a result, the current drill program will now probe below the entire 1,300 metre zone of anomalous gold identified in shallow scout diamond drilling conducted between 2018 to 2019 (see Figure 2).
Assays are awaited for the remainder of sampled intervals of holes FAVD0065 and FAVD0066, and for the entirety of holes FAVD0067 to FAVD0072. Hole FAVD0073, located 100 metres south of FAVD0064, is currently in progress. After its completion, the diamond rig will relocate south to test the Ruopas Isovaara nickel-copper-PGE target.

The following Tables are provided to ensure compliance with the JORC code (2012) edition requirements for the reporting of exploration results.
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 reported drilling was using MK Drilling of Ranua, Finland drilling NQ2 rod size with a DDH size of 75.7mm and core size of 50.7mm. NQ2 core samples are logged and marked up by S2 personnel. Unbiased core sample intervals were cut in half by diamond saw with half core sent for preparation and analysis at ALS Laboratories. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used |
Sampling and QAQC procedures are carried out using S2 protocols as per industry best practice. |
|
| 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 are sent to ALS Laboratories for analyses for gold and base metals. Drill core is sampled at S2’s facilities in Kittila, Finland. |
|
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc). |
Diamond drilling with NQ2 wireline bit producing a 50.7mm diameter core. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed |
Diamond Drill core recoveries are recorded by the driller and written on core block markers. The exact recovery is then recorded on a metre basis after core mark-up and recorded in the database. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples |
Sample quality is qualitatively logged on a metre basis, recording sample condition. |
|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
No relationship has been seen to exist | |
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
The logging uses a standard legend developed by S2 which is suitable for implicit wireframing. All diamond holes are geotechnically and structurally logged. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. |
All core has been photographed both dry and wet. Geological logging of the diamond drill holes is into tough books using standardised codes and templates. These logs are then imported into S2’s central database |

Core sawn in half and half core taken for assay. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
Not applicable | |
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
Samples were delivered by S2 personnel to ALS Minerals laboratory in Sodankyla, Finland, where they are crushed with >70% <2mm (code CRU-31), split by riffle splitter (code SPL- 21), and pulverised 1000grm to 85% <75 um (code PUL-32). Crushers and pulverizers are washed with QAQC tests undertaken (codes CRU-QC, PUL-QC). The prepared samples are forwarded to ALS Minerals Loughrea, Ireland, for analysis. |
|
| Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. |
Full QAQC system in place to determine accuracy and precision of assays |
|
| Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. |
For DDH’s non-biased core cutting through using an orientation line marked on core and cut to the line |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
Samples of appropriate size | |
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
All samples were analysed by ALS Minerals Loughrea, Ireland. Core samples analysed for gold undergo a 50g fire assay with AA finish (code Au-AA26). |
| For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. |
No geophysical tools were used to determine any element concentrations. |
|
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
Full QAQC system in place including Certified Standards and blanks of appropriate matrix and levels |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
all significant intercepts have been verified by senior S2 exploration personnel, including verifying against drill logging, core photos and/or direct visual inspection of drill core. |
| The use of twinned holes. | No twinned diamond holes have been drilled at Arnievalkea | |
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
Primary sampling data is collected in a set of standard Excel templates. The information is managed by S2’s database manager for validation and compilation into S2’s central database. |
|
| Discuss any adjustment to assay data. | No adjustments made | |
| Location of data points |
Accuracy and quality of surveys used to locate drillholes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. |
Diamond drill collars are pegged using a Trimble DGPS to +/- 1m accuracy. Drill rigs are aligned to Grid west using Standard Finnish National Grid ETRS-TM35FIN. The holes are downhole surveyed using a Deviflex tool. |
| Specification of the grid system used. | The grid system used is the Standard Finnish National Grid ETRS-TM35FIN. |
4/24 Parkland Road, Osborne Park, WA 6017, Australia. PO Box 1209, Osborne Park, WA 6916, Australia ABN 18 606 128 090 T +61 8 6166 0240 F 61 8 6270 5410 E [email protected] W www.s2resources.com.au
| Criteria | JORC Code explanation | Commentary |
| Quality and adequacy of topographic control. | Elevation data for all collars is determined by a digital elevation model derived from public domain 2m Lidar data. Topographic control and map data is excellent. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. | Recent drilling was not completed on a regular grid. Previous diamond drilling at Aarnivlakea has been completed on 40m drill spacings on lines between 80 – 240 metres apart. |
| 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. |
Data spacing and distribution is not sufficient at this stage to allow the estimation of mineral resources. |
|
| Whether sample compositing has been applied. | No sample compositing has been applied | |
| 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. |
Drillhole orientation is designed to intersect the mineralised package of rocks and be perpendicular to shearing and mineralisation. Structural measurements from orientated core indicate that the main fabric and contacts are dipping steeply to the east and hence holes collared at -60dip 270deg azimuth are appropriate. The two southern holes were drilled obliquely due to the local terrain, but the hole orientations are still considered appropriate. |
| 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 drilling at this stage is preliminary and exploratory. It is not possible to assess if any sample bias has occurred due to drillhole orientation at this stage. |
|
| Sample security | The measures taken to ensure sample security. | Chain of custody is managed by S2 personnel. Drill samples and core is visually checked at the drill rig and then transported to S2’s logging and cutting facilities by S2 personnel for logging, cutting and sampling. Bagged samples are transferred to ALS Laboratories in Sodankyla, Finland by S2 personnel. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
No audits or reviews have been conducted at this stage. |
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 Aarnivalkea prospect is located within the Paana Central Exploration Licence. ML2018:0081 The exploration licences are 100% owned by Sakumpu Exploration Oy, a Finnish registered 100% owned subsidiary of S2 |
| 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. |
All of the Exploration Licences are in good standing and no known impediments exist on the tenements being actively explored. |
|
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
The Aarnivalkea prospect is a greenfield discovery with historic BoT holes drilled in the region by Outukumpu not having been assayed for gold. |
| Geology | Deposit type, geological setting and style of mineralisation. |
The prospect is a shear zone hosted orogenic gold deposit within the Kittila Group of the Paleoproterozoic Central Lapland Greenstone belt.

| Criteria | JORC Code explanation | Commentary |
| 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. |
Refer to sample plans in text. |
| 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. |
All reported intersections of drilling undertaken by S2 have been length weighted. A nominal 0.2g/t lower cut-off is used for the reconnaissance diamond drill intersections. No top cut has been applied. |
| 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. |
High grade intervals internal to broader zones of mineralisation are reported as included intervals. |
|
| 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 the targets/prospects described is estimated to be dipping steeply to the east at approximately 75 to 80 deg. Refer to 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. |
All results considered significant are reported. |
| 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. |
