Si6 Metals Limited ( ASX: Si6 or the Company ) is pleased to announce results from recently completed soil and rock sampling, trenching and mapping at regional prospects in Botswana. The prospects are outside of the main Maibele base metals resource areas and are owned 100% by Si6. The fieldwork focused on the Maibele East, Mashambe and Gobajango prospects, targeting base and precious metals. Si6’s secondary focus was on assessing the prospectivity for pegmatite-hosted mineralisation such as lithium, caesium and tantalum, rare earths and gold.
Si6 is primarily exploring for base and precious metals in the Limpopo Mobile Belt in Botswana, a district known for hosting major nickel and copper producing operations. The Company’s portfolio contains an advanced Ni-Cu-Co-PGE resource at Maibele North and drilled high-grade Cu-Ag discoveries at Airstrip and Dibete that are in joint venture with BCL Limited ( BCL ), which has been in liquidation for several years. The joint venture tenements are controlled 60% by Si6 and 40% by BCL. The project contains nickel sulphide mineralisation related to ultramafic intrusions within mobile belt rocks and is broadly similar in style to other ultramafic intrusion-related mobile belt nickel discoveries such as IGO’s NovaBollinger ( ASX:IGO ), Chalice Mining’s Julimar ( ASX:CHN ) and the globally significant Thompson Belt in Canada. It currently hosts a resource of 2.4Mt @ 0.72% Ni and 0.21% Cu + PGMs + Co + Au.
Si6’s Technical Director, Mr Steve Groves stated, “These encouraging results in Botswana on our 100%owned tenure are a positive development for Si6 as we look to accelerate exploration activities in the country. Si6 intends to continue the work which has started on this tenure as we aim to build a stronger understanding of these areas and generate a number of priority drill targets for future programs.
“In addition to these activities, Si6 is also preparing to commence drilling at our joint venture ground in Botswana this year, with several key targets identified from previous work. We are currently progressing the required approvals to commence this work. Having exploration activities underway at both our joint venture and 100%-owned properties in Botswana is an exciting prospect that is now within our grasp and we look forward to updating shareholders on our progress in this regard.”
Joint Venture Project & Drilling Plans
The liquidators of BCL have recently provided consent for Si6 to undertake exploration and drilling activities on the joint venture tenements owned 60% by Si6 and 40% by BCL. Si6 is now progressing through approvals with relevant regulatory bodies. Drilling is currently planned for later in 2022.
Si6 has recently reported compelling drill targets from the significant amount of work undertaken including the 2021 geophysical programs, which substantially increased the chances of drilling success.

Maibele East & Mashambe Prospects
Regional exploration commenced at the Maibele East and Mashambe Prospects which both lie along strike to the northeast from the Maibele North Ni-Cu-PGM resource (Figure 2). Both prospects are located on Si6’s 100%-owned tenure and have been identified as priority, early-stage targets. Both prospects lie along an interpreted linear geological trend that passes through Maibele North and is possibly a preferential horizon for hosting Ni-sulphide deposits.
Work completed across the prospects included soil sampling along 40 x 2km lines spaced 200m apart, perpendicular to the regional lithology strike in order to cover the extents of the linear trend across, and in between, both prospects. Mapping around the sample sites has identified likely areas of ultramafic lithology with several GEOTEM conductors also evident along the trend.
Field portable XRF (FPXRF) analysis has been undertaken on the soil samples and has revealed elevated levels of elements such as copper, zinc and nickel coincident with the interpreted extension of the Maibele North linear trend through the grid.
Further work, including detailed mapping, further sampling and ground geophysics are required to generate drill targets in the area.

Gobajango Prospect
A further 60 soil test lines were completed across two grids at the Gobajango Prospect. The area has had minimal exploration and contains a GEOTEM anomaly and a dyke that transect the tenement (Figure 2). Mapping has revealed that the dyke cuts across gneisses and a gabbroic body. Elevated geochemical responses over the geophysical highs have been demonstrated from two soil test lines.
Geological field observations during the sampling program revealed a number of overgrown historic trenches excavated across a gossanous BIF horizon containing outcropping ultramafic occurrences
(Figure 7). The location of outcropping ultramafic rocks and spatially associated gossanous material coincident with airborne EM conductors (GEOTEM) confirms significant prospectivity of this new, underexplored area.
Samples from Gobajango have been analysed using the FPXRF and have revealed a number of anomalous base metal zones coincident with prominent GEOTEM anomalies in the area (Figures 5 & 6).
Twenty-five (25) lines at 200m spacing and 50m sampling interval were completed at Grid A. The FPXRF analysis shows a well-defined base metal trend coincident with the GEOTEM anomaly. Copper values generally correlate with amphibolite mapped in the field. Elevated nickel is evident in the FPXRF data where samples were taken from areas with mapped serpentinite. This is particularly encouraging, with ultramafic rock units such as serpentinite identified as the host rocks to mineralisation at the nearby Maibele North Ni-sulphide resource.

A total of 35 x 200m-spaced lines sampled at 50m intervals were completed at Grid B. Elevated responses strongly coincident with the elongate GEOTEM anomaly at the prospect were recorded in base metals such as Cu, Zn and Ni. Although outcrop in the area is poor, the FPXRF analysis has indicated that the GEOTEM anomaly is likely related to mafic-ultramafic rock types and presents as a target prospective for hosting sulphide mineralisation.

The soil sampling work at Gobajango has revealed two prospective targets containing elevated base metals in soils coincident with GEOTEM conductive anomalies and likely ultramafic-mafic geological sequences. These are the characteristics that often mark base-metal sulphide mineralisation in the region and elevates these prospects to targets worthy of further exploration.
Further work, including detailed mapping, further sampling and ground geophysics are required to generate drill targets in the area.
Secondary Exploration Targets (pegmatite-hosted mineralisation, rare earths and gold)
Si6’s portfolio contains Archean cratonic rocks as well as re-worked Archean rocks and has been shown to contain evidence of pegmatite dykes throughout. The Company’s portfolio abuts the Zimbabwe border where the same belt of Archean geology hosts one of the world’s largest lithium pegmatite mines at Bikita.
Si6 has previously undertaken a limited review and preliminary soil sampling to test for lithium, tantalum and other LCT pegmatite hosted metals to follow up on historic stream sediment samples (see ASX announcement on 27 February 2017). That work did reveal some anomalism in Li, Ta and Sn and often occurred coincident with elevated levels of all three elements which is a pattern that could be expected if they are related to mineralised pegmatites. Peak levels of Li, Ta and Sn are similar in tenor to those recorded from soil sampling in other areas of the world where LCT pegmatites occur. Si6 previously submitted 86 samples over 8km in the Maibele area. Samples were collected at 50m intervals from 42, 1km long lines spaced 200m apart.
The University of Botswana recently expressed an interest in undertaking a regional study of Si6’s portfolio for the potential to host strategic critical minerals such as lithium, tin, tantalum and rare earth
elements. Due to resourcing issues, the University has not yet been able to undertake a review but expects to be in a position to do so in the near term. As an interim step, Si6 commenced a desktop review and a brief field visit to search a couple of areas of interest. Several trenches were dug but no significant findings were made. Minor reconnaissance mapping did reveal some pegmatite bodies but these do not appear to be of the LCT type.
Si6 plans on commencing further reviews and a comprehensive field program in collaboration with the University of Botswana. Now that approval has been received from the joint venture partner, Si6 is in a position to conduct exploration on the joint venture tenements which are currently the most prospective for LCT pegmatite mineralisation based on prior work (see ASX announcement 27 February 2017). Si6 will also review the chemistry of regional granitic intrusions and look to identify fractionation trends associated with causative intrusion where prospective zones might occur on the Company’s ground.

Follow up soil sampling in area 1 showed elevation in Li, Ta and Sn (ASX Announcement 18/05/2016) and highlight the potential of Si6’s portfolio to contain strategic mineral mineralisation .
Acquisitions & Investments
Earlier in 2021, Si6 purchased 1,000,000 Cobre Limited ( ASX: CBE or Cobre ) shares which were valued at circa $90,000 (end of 2021). Si6’s strategy has always focused on exploration of both its projects in Botswana and Western Australia, in addition to the acquisition of projects or investments elsewhere.
As a result of ongoing delays in dealing with Si6’s joint venture partner, mainly due to the fact that they have been in liquidation for several years, the board made the decision to undertake regional exploration and seek out complementary acquisitions or investments elsewhere in Botswana. Cobre met the desired criteria and represented compelling value. That investment is now worth almost $500,000.
Cobre’s project is within the Kalahari copper belt of Botswana which is regarded as one of the most prospective areas globally for copper exploration by the US Geological Survey, with a number of coppersilver deposits currently under development. Cobre’s landholdings are along strike, and adjacent to, two major development projects: Cupric Canyon’s high-grade Zone 5 Cu-Ag deposit and Sandfire’s (ASX: SFR) T3 Motheo Cu-Ag deposit. Cobre is the second largest tenement holder in the highly prospective belt after Sandfire Resources.
Six weeks ago, Cobre confirmed it had made a significant copper discovery at its project from recent and ongoing drilling programs (see CBE’s ASX announcement on 27 July 2022). Initial drill programs were designed to test the first of 57 ranked priority targets. The footprint of mineralisation currently extends over 4km which is in line with the largest known deposits in the belt.

| Geology | •Deposit type, geological setting and style of mineralisation. |
•The main Prospect is hosted within the Magogaphate Shear Zone - a major geological structural feature, generally considered to mark the boundary between the Archaean aged (>2.5 billion year old) Zimbabwean Craton and the Limpopo Belt or Limpopo Mobile Zone (LMZ). The nickel-copper deposits of Selebi Phikwe lie within the northern part of the Central Zone of the Limpopo Mobile Belt, whilst the nickel copper deposits of Phoenix, Selkirk and Tekwane lie in the Zimbabwean Craton. The Central Zone of the LMZ comprises variably deformed banded gneisses and granitic gneisses, infolded amphibolites and ultramafic intrusions that that have the potential to host Ni-Cu sulphide mineralization. Cu-Ag mineralization at Dibete and Airstrip copper is spatially associated with dolerite intrusion •The Lepokole Shear Zone is equivalent to the Gobe Shear Zone of Temby (1999), which, like the Magogaphate Shear Zone, is a ductile strike slip shear zone, dipping steeply to the south, trending ENE-WSW. The Lepokole Shear Zone is around 5kms wide. Paya reports that a dextral sense of movement has been determined from S-C fabrics |

•No drilling reported in this release. |
| Data aggregation methods |
•In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. •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. •The assumptions used for any reporting of metal equivalent values should be clearly stated. |
•Only original data are reported with no weighting averaging or grade truncations. |
| 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 (eg ‘down hole length, true width not known’). |
•No drilling reported in this release. |

Further work will be determined upon a full analysis and interpretation of results. |
Appendix 2: Field portable Xray fluorescence method of analysis and equipment check against certified reference materials (CRM)
All field samples were analysed using the Innov-X Olympus Delta Premium Field portable XRF machine (FPXRF) using the soil mode setting. The FPXRF analysing time was set at 60 seconds analysis. The samples were collected on clear 50-micron sample bags. The sample bags were wiped clean with a microfibre cloth prior to analysis. The analyser sampled twice and the result automatically averaged.
The table below shows the performance of the FPXRF analysis against two certified refence materials from African Mineral Standards (AMIS) part of Torre Industries South Africa. AMIS 249 represented low grade copper standard and the grade used was obtained using 12 averages of the standards after calibration and checking with quartz powder blank. The average FPXRF copper result of the CRM checks over wide range of samples was 19% below average. A test run-on high-grade RC samples was done for high checks against the instrument using CRM AMIS 331. Same procedure used on low grade soils samples was applied for the high grade. The values were above average to the CRM copper value by 33%. On the current program it can be concluded that the copper values on the soils may be lower than actual by 19.6%. The FPXRF results are for differentiating between lows and highs across a range of geochemistry dataset.
