KCB – infill soil sampling increases target resolution on licence PL082/2018

Map showing the three anomalies of over 30ppm copper identified on PL082/2018, and the expended width of the Northern Zone target. These confirm and expand on the results previously provided on 26 August 2022: https://www.kavangoresources.com/media-library/news-release-media/rns26august2022.

13 Priority Target Areas in the KCB

13 Priority Target Areas in the KCB

PL036/2020

  • Redox Horizon on the southern limb of the Acacia anticline Acacia Fold nose
  • Possible prospective lithology repetition, domes, as seen on mines elsewhere on KCB
  • Possible structural repetition: Thrusting or folding
  • Major soil sampling program completed, has identified 4 geochemical anomalies of +10ppm Cu (peak value of 110ppm Cu) – Acacia (c.2.5km x 3km), Morula (c.3km x 3km), Happy (c.9km x 1km) & Kudu (c.18km non-continuous strike)
  • To be followed by RC drill program

 

PL082/2018

  • Located in NE heart of the KCB
  • Kanye 90% earn-in with local company
  • AEM suggests licence area is analogous to the Banana Zone deposit
  • Soil sampling completed August 2022 and identified 2 geochemical anomalies of +30ppm Cu:
    • Northern Zone 8km strike (peak value of 39.7ppm Cu)
    • Central Zone 27km strike (peak value of 118.8ppm Cu)
    • Drill ready

 

Mamuno (PL49/2020 and PL52/2020)

  • These four licences form a large contiguous block strategically located on the KCB, adjacent to border
  • Mineralisation known on both sides of border
  • Minimal previous exploration & lack of regional AEM data, creating the opportunity for a new discovery
  • Kanye has newly identified a large 5km x 3.5km +30ppm Cu anomaly (peak value 73ppm Cu)
  • D’kar/Ngwako Pan contact located by Kanye, soil sampling values align closely with this

KCB – target definition PL082/2018

This shows the two linear anomalies of over 30ppm copper identified on PL082. These align with the mapped geology, this is encouraging as it provides strong indications of in-situ mineralisation. They are notable for their significant strike length.

 

 

Banana Zone 1 – the lower images show (right hand side) the conductor identified on the Banana Zone that is associated with mineralisation, and (left hand side) the results of Kavango’s 2021 AEM survey, which identified a similar feature.

 

 

Banana Zone 2 – this shows the relative positions of Kavango’s 082 licence and the established Cupric Canyon owned Banana Zone resource.

KSZ Project Update

KSZ Project Update

The Q2 2022, TDEM campaign was conducted in 3 phases. Loop 8 and its lines were prepared first, together with the locations for Loops 10 and 11. The infill lines for Loops 10 and 11 were then cut, together with the location for Loop 12. Two final infill lines were cut for Loop 12 in the third phase.

 

 

The B1 Conductor was identified originally via Surface TDEM from Loop 8, which was resurveyed at the start of Q2 2022 to confirm the original data.  New survey lines were acquired using Loop 8.  The Z Component gridded results are shown here, clearly identifying the B1 Conductor.  Preliminary modelling has indicated a 13,450 siemens conductance.

 

Loop 10 was prepared to investigate vertical conductors at the B1 Conductor.  It detected two new conductors, the B3 and B4 Conductors.  The responses for these are clearly evident in the gridded Z component for Loop 10.  Preliminary modelling estimates both at 4,350 siemens conductance.

 

 

This map shows Loops 4, 8, 10, 11 and 12, positioned over the B1, B3 and B4 conductors. Loop 4 was the original TDEM Loop, acquired in Q2 2021, that first identified the B1 conductor. Anomaly B2 was identified from Surface TDEM and a Downhole EM survey acquired using Hole KSZDD002. Kavango currently interprets Anomaly B2 as a possible geological fault that may have acted as a controlling structure for Ni-Cu-PGE bearing intrusive magma.  The Z Component of the Surface TDEM data is shown here, merged for Loops 8 and 10.  This clearly shows the conductive responses for the B1, B3 and B4 Conductors.

 

This map shows the First Vertical Derivative and interpretation of Kavango’s Ground Magnetic Data over the Great Red Spot. It shows the position of the B1 Conductor and Anomaly B2, the possible geological fault. Note that Anomaly B2 appears to be quite parallel to a probable dyke lying just to the north.  The interpreted ENE and NW striking dikes, and related parallel structures, are possible conduits for  Ni-Cu-PGE bearing intrusive magma.

 

This idealised conductivity table provides a comparative assessment of the range of conductivities in siemens per metre, observed for various rocks and mineralization. This helps inform Kavango’s ranking of potential drill targets based on the modelled conductance estimations in siemens.

 

Figure 8. Geological cross-section of the Talnakh ore field. Intrusions are not to scale

This North looking geological section of the Talnakh and Kharaelakh ore bodies (in red) at Norilsk illustrates their close proximity to the steeply dipping Noril'sk-Kharaelakh Fault (hachured white line) and their near flat-flying orientation. Note the “bend” in the red ore body at the base of Kharaelakh intrusion, which emphasises the potential complex geometry of the intrusion and the massive sulphides.

 

 

 


Figure 2. Position of the orebodies (after Natorkhin et al., Turovtsev). Projection on the surface;

The plan view of the Talnakh and Kharaelakh intrusions illustrates how these generally <1km diameter bodies occur in clusters, close to the NNE striking Noril'sk-Kharaelakh Fault (black line). This shows that Kavango’s B1, B3 and B4 conductors conform to a model Talnakh and Kharaelakh type ore bodies.

The comparison shows that the conductors detected by Kavango are of a similar size to several of the massive sulfide bodies at Norilsk. Not just that, but they are clustering together in a manner similar to parts of the Kharaelakh and Talnakh branches of the orebody.  Further, all of the massive sulfides at Norilsk lie within close proximity to the Kharaelakh fault, which is a similar scenario to Kavango's conductors in close proximity to the B2 fault.

D Inversion of Aeromagnetic data for Target i10 with AMT section and planned drillholes. The causative geology for the magnetic signatures is interpreted to be close to surface. The depth of overburden from this AMT section is interpreted to be ~120m. This target in interpreted as a simple single phase carbonatite phase/pipe with a possible outer ring indicated by a weak magnetic low.
