AIRSTRIP IP SURVEY CONFIRMS EXCITING 2.5KM ANOMALY IN BOTSWANA
Highlights
-
Gradient Array and Pole Dipole Survey completed at Airstrip prospect, Botswana
-
2.5km long IP Gradient Array anomaly confirmed by Pole Dipole IP
-
Numerous additional IP targets generated
-
Strong potential for deep-seated mineralisation and new discoveries
-
Maibele North survey results pending
Si6 Metals Limited ( ASX: Si6 or the Company ) is pleased to provide an update on the Induced Polarisation ( IP ) survey recently completed at the Airstrip Prospect, 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 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 ongoing program in Botswana is proving to be a great success with current surveys having now highlighted two 2.5km anomalies at Dibete and Airstrip. There are some great target areas along strike of the known mineralisation, demonstrating strong potential for deep seated mineralisation which warrant further exploration and as such, the Company will be planning for reverse circulation and diamond drilling programs.”

AIRSTRIP PROJECT
Si6 announced results from a Gradient Array IP survey across the Airstrip Prospect earlier this year (see ASX announcement on 6 January 2021). The Gradient Array IP detected numerous anomalous chargeability zones and to facilitate the design for deeper drilling, the survey was followed up with discrete N-S lines of Pole-Dipole IP surveys across priority anomalies to further map the accurate locations of potential sulphide mineralisation.

ASX Announcement
Gradient Array IP
The Gradient Array data shows a number of prominent IP high chargeability anomalies corresponding with an IP low resistivity anomaly, and in some instances, strong surface geochemical response (see Figures 2 and 3). The Gradient Array IP data corresponds well with mineralisation intersected by previous drilling and further work along strike and at depth of these bodies is warranted at the project. The Gradient Array IP highlighted three priority anomalous zones for immediate follow up:
Anomaly 1 is located on the NE edge of the survey area and is coincident with historically drilled coppersilver lodes at Airstrip. The high chargeability zones are offset slightly to the east of the main drilled mineralisation at Airstrip and extend along strike towards the Maibele North Ni-Cu-PGE orebody.
Anomaly 2 presents as a large area of multiple strong chargeability responses in the southwest corner of the survey area. The NW-NE tending structural regime is still evident and the anomaly is also spatially associated with a large NW-trending dolerite dyke, the type of which have been noted to be associated with high grade copper and silver mineralisation in drill holes at Airstrip. This large area also contains a NE-striking magnetic body that potentially represents a mafic-ultramafic body that appears to be the extension of the ultramafic rock types associated with the Maibele North Ni-Cu-PGE orebody.
Anomaly 3 is located in the northern part of the survey and is a NE-trending, >1km long linear chargeability high directly associated with a strong NE-trending copper-in-soil anomaly in an area that has never been drilled previously. Field reconnaissance has shown copper-oxide mineralisation (malachite) to be present at surface at Anomaly 3.
Existing magnetic surveys indicate two NW-SE trending dolerite dykes at the northern and southern extent of the Airstrip IP anomalies. Dolerite dykes have been noted to be associated with Cu-Ag mineralisation at both the Dibete and Airstrip prospects. Additional work along these dykes, corresponding with IP anomalies is also warranted.

ASX Announcement
Pole Dipole IP
Pole dipole IP surveys were completed along 12 N-S lines perpendicular to the general strike direction of the Airstrip Gradient Array anomaly and coincident Cu-Ag mineralisation. The Pole Dipole survey was designed to test some of the most prominent Gradient Array IP anomalies to gain an understanding of targeting depth and to help characterize the anomalies further. Some of the areas previously drilled were also flagged for follow up to help generate better drill targets.
Results from the PDP surveys indicate prominent chargeability anomalies extending to depth that generally correspond to the IP Gradient Array data (Figure 3). Gradient Array anomalies 1, 2 and 3 all generated strong PDP responses and warrant drill testing as well as more IP lines with wider dipole spacings to extend the anomaly strike lengths and generate even deeper targets.
Anomaly 1 Pole Dipole IP modelled sections
The PDP lines at Anomaly 1 are located to the immediate southeast of the Maibele North Ni-Cu resource and run across some of the drilled high grade Cu-Ag mineralisation at Airstrip (Figure 4). The chargeability response shows 2 strong chargeability anomalies with coincident resistivity lows that both correspond to known mineralisation at Maibele North and Airstrip but also reveal deeper and parallel targets that have yet to be drill tested. The data indicates that there is good potential to discover mineralisation at Airstrip further to the east and at depth and also to extend the Maibele North mineralisation to the SW.

ASX Announcement
Anomaly 2 Pole Dipole IP modelled sections
Anomaly 2 lies to the southeast of Maibele North and Airstrip and shows a large area that contains numerous gradient array IP anomalies (Figures 5 & 6). Eight PDP lines were undertaken across Anomaly 2 and all showed strong IP chargeability and resistivity anomalism. A particularly striking feature of the chargeability response is the linear nature of the corresponding highs across the zone, indicating a prospective zone extending for at least 2 km. Dolerite dykes are known to traverse the area and other geophysical datasets such as magnetics indicate potential for ultramafic bodies and highlight the potential for Anomaly 2 to host numerous mineralisation styles. Elevated copper-in-soils are also associated with the 2km long anomalous zone. The two historic holes drilled in the area did not test the currently defined IP anomalies in this zone.

Deep resistivity lows that warrant drill testing
----- End of picture text -----
Figure 6: Anomaly 2 PDP resistivity response which represents a newly discovered zone with strike length well over 2km. Several deep resistivity lows are evident across the zone at every PDP surveyed line and present as attractive drill targets.
Anomaly 3 PDP modelled sections
Two lines were undertaken at Anomaly 3 to test the gradient array response and extend the anomaly further to the west (Figure 7). Two strong coincident chargeability highs coincident with resistivity lows were identified and further IP is required to fully define the extent of these anomalies. The zones correlate well with strong historic linear copper-in-soil anomalies and have defined a new target zone for Si6. The resistivity lows warrant immediate drill testing but further geophysics is likely to define more drill targets.

Maibele North Prospect survey
At Maibele North Ni-Cu-Co-PGE prospect, an Audio magnetotelluric (AMT) technique has been undertaken to detect massive to semi-massive sulphide bodies that might extend the known Maibele North sulphide mineralisation at depth and/or along strike. The Maibele North sulphide resource is open in all directions. Data for the prospect is currently being processed and interpreted by the Company.
Future Work Program
The geophysical programs are designed to locate sulphide mineralisation for follow-up drill testing. Quotes from reliable in-country drill companies are being sought, with a view of following up the geophysical targets with a combination of RC and diamond drilling.
