MAIBELE NORTH SURVEY DELIVERS NUMEROUS & SIGNIFICANT UNTESTED TARGETS
Highlights
-
27-line AMT Survey completed across Maibele North Ni-Cu-Co-PGE Project, Botswana
-
Survey accurately mapped existing sulphide mineralisation
-
Numerous untested sulphide targets identified below and along strike of the current resource
Si6 Metals Limited ( ASX: Si6 or the Company ) is pleased to provide an update on the recently completed Audio-frequency Magnetotellurics (AMT) survey conducted at its Maibele North Project in Botswana. Si6 is exploring for base and precious metals within the Limpopo Mobile Belt in Botswana, a district known for hosting major nickel and copper producing operations.
The Company’s Botswana portfolio contains an advanced Ni-Cu-Co-PGE resource at Maibele North and drilled high-grade Cu-Ag discoveries at Airstrip and Dibete. Si6 is currently undertaking a multi-faceted exploration campaign, employing a variety of ground geophysical techniques designed to target deeper mineralisation for follow-up drill testing.
Si6 Executive Chairman, Patrick Holywell stated , “Our Botswana program is continuing in its success with our latest AMT Survey not only accurately mapping the existing sulphide mineralisation, but identifying numerous untested sulphide targets both below and along strike of our current resource. This follows our recently announced identification of two 2.5km anomalies identified at Dibete and Airstrip.
“Through our targeted approach, which utilises various ground geophysical techniques to target deeper mineralisation, we are really starting to gain better understanding of what we are dealing with and in turn, plan our future drilling programs in more detail. We anticipate following up the AMT targets with a combination of RC and diamond drilling, in addition to planning for further AMT surveys to the east and west of the current survey area.”

MAIBELE PROJECT
AMT is an electromagnetic geophysical technique that measures local magnetic and electric fields which are used to determine in-phase and out of phase ground resistivity values. AMT can use artificial sources or natural sources, such as were employed in this survey. A previous trial line of AMT east of Maibele North detected the Ni-sulphide mineralisation intersected at around 400m vertical depth in drill hole MARD0094.
The aim of the AMT survey completed over Maibele North was to search for extensions of mineralisation below and along strike of the current Maibele North resource estimate envelope. Evidence of deeper mineralisation at Maibele North has previously been confirmed by Si6 with two adjacent holes on the Eastern section of the prospect, drill holes MADD0153 and MARD0094, where nickel sulphides were intersected in both holes with assay results below (see ASX Announcement 19 March 2021). Almost no drilling to date has been undertaken beneath the main Maibele North mineralisation envelope.

AMT RESULTS
Maibele North Main
The Maibele North orebody contains a multi-commodity Ni-Cu-Co-PGE Mineral Resource Estimate (MRE) of 2.38Mt which is open along strike and at depth (for MRE details see Supplementary Appendix). The AMT survey covered the entire resource area as well strike extensions and has succeeded in mapping the known sulphide mineralisation, as well as detecting several significant zones of anomalism beneath the known orebody that remain untested by drilling (see Figure 2 and 3). The deeper, untested zones occur as distinct anomalies and generally lie beneath the thicker zones of mineralisation within the orebody. For example, the most prominent AMT anomaly beneath the orebody lies below the thickest massive sulphide occurrences in hole MADD0057, where over 15m of massive sulphides have been intersected (see Figure 3).
The results of the survey over Maibele North provide great encouragement for the effectiveness of the AMT to detect further mineralisation and potentially extend the orebody deeper below the current resource envelope. Historic drilling as part of the MRE in 2014 is limited to above 250m vertical depth.

Note the prominent, deeper zone on Line 10 that has never been drill tested.
MARD0094-0153 (Maibele East)
The AMT has detected a large, strong anomaly corresponding to the mineralisation intersected in MARD0094 and has confirmed that the narrow Ni-sulphide mineralisation intersected in MADD0153 lies on the periphery of this very prominent zone (Figures 2 & 4). The AMT anomaly in this area is located south of MADD0153 and the strength of the response in the area of the MARD0094 mineralisation is modest compared to the very strong response extending to the west and south of these two drill holes. A further strong response is located on the extreme eastern edge of the survey and will require further AMT lines to fully define.
The AMT has highlighted the significant potential to discover further Ni-sulphide mineralisation at depth and down-plunge of the Maibele North resource in the area of MARD0094 and MADD0153.

Recent hole, MADD0153, is projected onto the section from the east and only clipped the edge of the modelled anomaly. The AMT response extends for over 300m in strike, mostly to the west of MARD0094 and is untested by drilling.
Airstrip
The AMT survey extended to the southwest to cover a portion of the Airstrip target area. The results showed a small but strong response coincident with, and beneath, some of the shallow high-grade CuAg mineralisation intersected in previous drilling. The results are encouraging and indicate a potential deep source of mineralisation beneath the shallow high grades. Further AMT lines are required in this area to resolve accurate drill targets.
SUMMARY
The AMT survey has been highly successful in defining a number of very prospective drill targets below and along strike of the Maibele North Ni-sulphide resource. Si6 has high confidence that these targets are likely to represent further sulphide mineralisation given the technique’s effectiveness in mapping known areas of mineralisation. The survey has highlighted deep anomalies beneath some of the thickest sections of the Maibele North resource as well as confirming the near miss of MADD0153 in relation to a very large down-plunge anomaly to the east of the main resource. Further strong anomalies are indicated on the edge of the survey highlighting the need for additional AMT surveying in the area.
FUTURE WORK PROGRAMS
The AMT has defined a number of drill targets prospective for the discovery of additional Ni-sulphide mineralisation. Quotes from reliable in-country drill companies are being sought, with a view to following up the AMT targets with a combination of RC and diamond drilling. Si6 is also reviewing the results with a view to planning further AMT surveys to the east and west of the current survey and possibly elsewhere across the Company’s priority targets.
