ELECTROMAGNETIC SURVEY STARTED AT KOONENBERRY
Key Points
-
S2 has commenced a ground electromagnetic survey at its Koonenberry nickelcopper project, NSW
-
Collation of results from previous wide spaced drilling confirms presence of nickel-copper sulphide occurrences
-
First of several surveys which will systematically cover the belt
S2 Resources Ltd (“S2” or the “Company”) advises that the first of several planned ground-based electromagnetic (EM) surveys has commenced at its 100% owned Koonenberry project in northwestern New South Wales (NSW). It is a regional-scale project covering 2,712 square kilometres and 140 strike kilometres of geology considered prospective for magmatic nickel-copper sulphide mineralisation.
The initial EM surveys will cover two parts of the Company’s tenure following the signing of land access agreements with relevant pastoral lease holders (see Figure 1). It is anticipated that this coverage will sequentially expand as more access agreements are concluded. The survey is expected to take two months, with results available in January 2024.
The initial EM survey comprises a combination of moving loop (MLEM) and fixed loop (FLEM) survey configurations using the highly sensitive deep penetrating ARMIT B-field system.
Meanwhile, collation of results from shallow and wide-spaced previous drilling by INCO/Vale and Carpentaria Exploration has confirmed the fertility of the belt for magmatic nickel-copper sulphides, with evidence of mineralisation having been intersected in several previous holes (see Figure 2). Key results from within the project area include:
-
7 metres @ 0.46% nickel from 7 metres in hole CKOAC0053 (aircore) at Bald Hill South
-
10 metres @ 0.35% nickel from 2 metres, including 3 metres @ 0.54% nickel and 0.1% copper from 3 metres in hole CKORB0160 (RAB) at Packsaddle
-
4 metres @ 0.22% nickel and 0.11% copper from 31 metres in hole RC12KB008 (RC) at Packsaddle
-
4 metres @ 0.3% nickel from 5 metres in hole CKORB0195 (RAB) at Highway
Furthermore, assessment of open file data confirms the presence of magmatic sulphides in the form of disseminated pentlandite, chalcopyrite and violarite in samples from old holes drilled at Packsaddle and Mt Arrowsmith East, located just outside of S2’s tenement boundary (see Figure 2).

Project geology and background
==> picture [286 x 139] intentionally omitted <==
The project is located 130km northeast of Broken Hill astride the Silver City Highway and covers 140 kilometres of strike of prospective stratigraphy of the Koonenberry Belt, a craton margin mobile belt where a series of mafic-ultramafic sills intrude the late Proterozoic to Cambrian Mt Arrowsmith volcanics. The project area covers that part of the belt that is deemed amenable to exploration in technical and financial terms by virtue of being either exposed at surface or being only buried by relatively shallow (less than 100 metres) of later (post-Carboniferous) cover. It contains a prominent elongate gravity high which coincides with numerous linear magnetic highs, which is interpreted to represent a slice of dense volcanic crust intruded by numerous mafic and ultramafic sills, of a similar scale to the Fraser Complex within the Albany-Fraser belt that contains the intrusion hosting Nova (Figures 3 and 4).

Figure 4. Regional magnetic image showing northwest striking linear grain reflecting abundant sills intruding the belt.
Whereas the Albany-Fraser belt is Proterozoic in age and wraps around the southeastern margin of the Yilgarn Craton, the Koonenberry Belt is late Proterozoic to Cambrian in age and wraps around the northeastern margin of the Curnamona Craton (Figures 5 and 6). Both are accretionary mobile belts containing nickel prospective stratigraphy.
The prospective stratigraphy at Koonenberry comprises 140 strike kilometres of the Mt Arrowsmith Volcanics which contain extensive sills and intrusions described as gabbros with comagmatic orthocumulate ultramafic picrites. These rocks are readily identifiable in the regional airborne magnetics (Figure 3) and are petrographically similar to those that host mineralisation in the Russian Pechenga Ni-Cu-PGE camp, comprising distinctive olivine-rich orthocumulates with abundant intercumulus red hydrous hornblende (Kaersutite). The Pechenga camp contains roughly 25 Ni-Cu-PGE

mines containing approximately 4.7 million tonnes of nickel and 2.4 million tonnes of copper, mainly hosted in the basal sections of the thicker ferropicrite sills and intrusions, and is close to the giant Sakatti Ni-Cu-PGE deposit just across the border in northern Finland.

Figure 5. Location map of the Koonenberry Belt showing and a comparison to the Fraser Zone of the Fraser Range which hosts the Nova-Bollinger deposit. The Koonenberry Belt is located on the north-eastern margin of the Curnamona Craton.
Koonenberry also resembles other magmatic Ni-Cu-PGE sulphide endowed belts such as the CircumSuperior Belt of Canada, (which is also an accretionary mobile zone wrapped around the northern margin of the Superior Craton) which hosts the giant Raglan and Thompson Ni-Cu camps. In fact, this was the model that the S2 team (then as Sirius Resources) used to identify the prospectivity of the Fraser Range, leading to the discovery of Nova.
In terms of the above, plus the presence of extensive primitive orthoculmulate ferropicrite sills intruding sulphidic and carbonaceous sedimentary rocks, Koonenberry closely resembles the Pechenga Belt, and minor occurrences of magmatic pentlandite and chalcopyrite have been identified in outcrop in some orthocumulate picrites from the Mt Arrowsmith area.

Acknowledgment and appraisal of exploration by other parties. |
The first recorded exploration for nickel mineralisation was by CRAE who completed a regional stream sediment sampling program identifying anomalous ultramafic rocks at Mt Wright/ Macs Tank, Conns Creek and Wyndonga. Follow-up soil and rock chip sampling focussed on Mt Wright/ Macs Tank (located south of the Koonenberry project, now within the Mootwingee National Park). CRAE concluded the project was unlikely to be of economic significance and withdrew from exploring the area. Vale / Inco explored for magmatic nickel-copper sulphide mineralisation between 2005 and 2009. Work included mapping, soil and rock chip sampling, detailed aeromagnetic survey, ground electromagnetic surveying and drilling (RAB/AC, RC and diamond). Vale identified nickel-copper sulphide mineralisation at the Mt Arrowsmith East prospect as well as anomalous nickel in RAB/aircore drilling at Bald Hill South, Packsaddle and Highway. In addition, copper staining was observed at the Mt Arrowsmith Cu-Ag (MAC) prospect, hosted in basalt and interpreted to have potential affinities with Keweenaw- Cu mineralisation (Michigan, USA). |
| Carpentaria Exploration undertook exploration between 2011 and 2014.. Work included rock chip sampling and mapping, magnetic modelling and limited RC drilling, intersecting nickel- copper sulphides at the Packsaddle prospect. In 2017, IGO completed a series of AMT geophysical lines over the belt. Although most of the work was completed north of the current project area, a single line did extend through the very north of the project area. |

| Geology | Deposit type, geological setting and style of mineralisation. |
The project area cover part of the Koonenberry Belt, an exposed segment of the continental Late Neoproterozoic to Early Cambrian rocks in far western New South Wales. Intra- contintental rifting associated with the Neoproterozoic breakup of the Rodinia supercontinent resulted in the deposition of the shelf to slope sediments (silt, mud and dolomite) of the Kara Formation. During sediment deposition in a shallow sea, contemporaneous rifting resulted in the eruption of bi-modal, alkaline, sub-aerial to submarine pyroclastic tuffs and lava flows of the Mount Arrowsmith Volcanics, along with feeder gabbroic sills and likely comagmatic orthocumulate ultramafic picrite sills and intrusions. The ultramafic intrusions associated with the Mt Arrowsmith Volcanics are considered prospective for magnetic nickel-copper- PGE mineralisation. The tectonic setting resembles other magmatic Ni-Cu-PGE sulphide endowed belts such as the Circum- Superior Belt of Canada, which hosts the giant Raglan and Thompson Ni-Cu camps. Petrographically, rocks are considered petrographically similar to those that host mineralisation in the Russian Pechenga Ni-Cu- PGE camp, with distinctive olivine-rich orthocumulates with abundant intercumulus red hydrous hornblende (Kaersutite). Adding support to the model, previous exploration has identified trace to minor amounts of co-magmatic nickel sulphides (pentlandite, and vilolerite) and copper sulphides (chalcopyrite) within ultramafic picrite rocks. |
| 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. |
Results of material drill holes is provided in Table 1. All drilling is historical in nature verification and validation of these data sets are ongoing. |
| 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 results reported are historical in nature and cannot been verified. Where intervals have been reported a cut-off grade of 0.15% Ni and/or 0.1% Cu has been used with no top-cut applied. Intervals have been calculated by length weighting individual assays and using a nominal maximum internal dilution of 2 metres. |
| 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. |
Where aggregate intercepts include individual zones of higher grade these are reported, using the same methodology as for the larger intervals. The lower cut-off grade for the including intervals is reported in the relevant tables. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalent results have been 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’). |
All drilling and sampling on the project are historical in nature and verification and validation of these data sets are ongoing. S2 is unable to determine any relationship at this stage and all results reported are downhole lengths only and true widths are unknown. |
| 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 historical 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. |
A Geoscience Australia airborne electromagnetic survey (SkyTEM) survey has been flown on nominal 2.5kilometre line spacing over the project area. The line spacing is not considered sufficient to effectively explore for magmatic nickel-copper sulphide mineralisation, although the survey has shown that much of the project area has conductive cover, significantly limiting the effectiveness of any such survey. Various isolated MLEM geophysical surveys have been carried out within the project (Figure 1). These surveys have been reviewed by the company’s geophysical consultants (Newexco). The historical MLEM surveys have not identified any bedrock conductors within the limitations of the surveys (estimated to be approx. 200 metres depth penetration). Inco/Vale have flown a 100-metre line spaced aeromagnetic and radiometric survey over much of the project area. This data has been merged into the regional dataset. Other exploration has included rock chip, stream sediment and soil sampling, and any material results have been reported. |

S2 intends to undertake systematic early-stage exploration over the Koonenberry project area, using ground EM (MLEM and reconnaissance FLEM) surveys, combined with surface prospecting (including mapping, rock chip sampling and ultrafine soil sampling) in areas where prospective stratigraphy. |
