The company’s Botswana portfolio contains an advanced nickel-copper-cobalt-PGE resource at Maibele North, as well as drilled high-grade copper-silver discoveries at Airstrip and Dibete.

Si6 Metals (ASX:SI6) has completed its Mailbele AMT survey within the Limpopo Mobile Belt in Botswana – a district known for hosting major nickel and copper producing operations – after defining and extending its existing anomalies.

The company has been undertaking a multi-faceted exploration campaign employing a variety of ground geophysical techniques designed to target deeper mineralisation for follow-up drill testing.

Confidence remains high on upcoming drilling campaign

“The Maibele AMT survey has proven very effective at mapping existing nickel-sulphide mineralisation at Maibele North,” Si6 executive chairman Patrick Holywell said.

“There is certainly great potential to make additional nickel discoveries – the 2021 geophysical survey programs have now been completed with outstanding results achieved.”

“We are confident of a successful upcoming drilling campaign and look forward to the commencement.”

Maibele project details

During 2021, the exploration company completed an initial 27-line Audio frequency Magnetotellurics (AMT) survey across the Maibele North orebody to search for deep extensions of mineralisation below and along strike of the current Maibele North Resource.

Evidence of deeper mineralisation at Maibele North has previously been confirmed by Si6, with two adjacent holes on the Eastern section of the prospect, MADD0153 and MARD0094, where nickel sulphides were intersected at depth in both holes.

Results of the initials survey over Maibele North provided great encouragement for the effectiveness of the AMT to detect further mineralisation and potentially extend the orebody deeper below the current resource envelope, the company said.

Several prominent anomalies were detected on the edge of the survey, and Si6 recently completed a series of extensions and extra lines to close off these zones in preparation for drill targeting.

Results of the extension survey have confirmed the existence of several deep target zones and resolved some of the edge effects of the initial survey.

Notable zones

Three notable zones are evident:

  • A strong conductor extending vertically to depth beneath the thickest section of the Maibele North orebody;
  • A large, south-dipping zone starting below, and to the south of, the main orebody and extending to edge of the survey; and
  • A large, south-dipping anomaly that extends mostly eastwards from the deep sulphide mineralisation intersected in holes MARD 0094 and MADD0153.

Si6 says all three zones represent “excellent, large drill targets and provide real potential to increase the Ni-CuCo-PGE sulphide mineralisation at Maibele North.”
