HIGH PRIORITY DRILL TARGETS GENERATED FROM DIBETE AMT SURVEY
Highlights
-
Impressive results from 14-line AMT Survey at Dibete have been received, generating multiple drill targets
-
The results show numerous high quality untested anomalies beneath and along strike from known mineralisation
-
Results from lines 3-7 deliver strong AMT result consistent with “Messina Copper” style mineralisation, weighing further support of the potential for Dibete to host breccia-pipe style of copper mineralisation
-
Recent AMT surveys at Maibele North have demonstrated the technique accurately maps existing sulphide mineralisation
-
Multiple high priority drill targets have been generated which will be incorporated into the Company’s upcoming drilling program
-
Results from Airstrip and Maibele North AMT surveys currently pending
Si6 Metals Limited ( ASX: Si6 or the Company ) is pleased to announce the results of the 14 lines of AMT surveying at the Dibete prospect from the Company’s extensive geophysical survey across the Maibele Base Metals Project in Botswana (see ASX Announcement 21/09/2021). 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 previously drilled high-grade Cu-Ag discoveries at Airstrip and Dibete. Si6 is undertaking a multi-faceted exploration campaign, employing a variety of ground geophysical techniques designed to target deeper mineralisation for follow-up drill testing.
The Company has completed a 34-line AMT survey at all three prospects (Dibete, Airstrip & Maibele North) and has now received data for Dibete. Results from the surveying at Airstrip and Maibele North is currently pending. Previous AMT surveys at Maibele North successfully mapped the known sulphide mineralisation and identified numerous deeper targets for drill testing (see ASX Announcement 14/07/2021).
Si6 Executive Chairman, Patrick Holywell stated , “The AMT Survey model we are using in Botswana has proven yet again that it is a very successful model in identifying targets for drilling programs. With the results in now for Dibete, we can clearly see that multiple high-quality targets exist both beneath and along strike from known mineralisation. We are currently in the final stages of completing our targeting exercises for the upcoming drill program at Dibete and will update the market accordingly. We eagerly await the results from the AMT survey at Airstrip and Maibele North and then onto drilling as soon as possible.”

Dibete AMT Results
The AMT survey was designed to cover areas of the recently defined coincident IP/VTEM responses that encompass previously drilled high-grade Cu and Ag mineralisation (see ASX Announcement 24/06/2021). Results from the 14 lines show strong conductive anomalism close to surface and coincident with the previously defined Gradient Array IP and Pole Dipole IP responses. The AMT technique sees much deeper than the two IP techniques and has defined some outstanding deep anomalies, particularly from Lines 3 to 7 beneath the area of high-grade near surface Cu-Ag mineralisation (Figures 3 to 5).
Lines 3 to 7
Lines 3 to 7 traverse the area of drilled near surface copper and gold mineralisation and show a very promising, strong AMT response beneath the shallow, high-grade mineralisation. The response models as a vertical, pipe-like body and is geometrically reminiscent of the breccia-pipe style of copper mineralisation in the Messina Copper district (Figures 9 & 10). This type of AMT response adds further support to the interpretation of Messina Copper style of mineralisation present at Dibete and will be a high priority drill target in the upcoming drill campaign.

Lines 1 & 2
Lines 1 and 2 lie at the southwestern edge of the survey and display a shallow response that is coincident with the IP responses as well as a second, deeper response that extends to beyond 600m depth in a position vertically below the near surface response (Figure 6). Although deep, this could present as a very good drill target if drilling elsewhere establishes that the AMT response represents sulphide mineralisation at depth.

Lines 10 & 11
Lines 10 and 11 traverse a strong VTEM conductive zone that lies coincident with the IP chargeability/resistivity response. The AMT survey has revealed a strong response at around 150m depth and presents as a strong drill target. Historic hole, DBRC0024, intersected elevated Lead, Sulphur, Zinc and minor Copper in a 30m thick zone that corresponds to the upper reaches of the AMT anomaly on Line 10. The stronger down-dip portion of the anomaly is an enticing drill target.

Lines 12 & 13
Moderate, shallow AMT responses were recorded on Lines 12 and 13 and form secondary priority drill targets for future programs.
The Messina Copper Deposits
The Messina Copper district contains multiple high-grade copper deposits comprising breccia pipes, disseminated replacement and fissure deposits centred on NW-NE structural intersections within highgrade metamorphic rocks of the Limpopo Mobile Belt[1] , similar to those seen in the Magogophate Shear Zone. The Messina deposits were discovered initially by the recognition of narrow, high-grade copper veins close to surface, with the larger orebodies extending to over 1,400m depth spaced over a 15km strike zone (Figures 9 & 10). Similarities between Messina and Dibete/Airstrip, including the presence of narrow, extremely high-grade copper veins, spatial association of Karoo-aged dolerite dykes and mineralisation located on NW-NE structural and geological trends all suggest that this style of mineralisation is a valid target type for the Magogophate Shear Zone.
