Hillside Prospect 3 Assay Results
ZIM: Multiple zones grading >0.5g/t at Prospect 3
Kavango Resources plc (LSE: KAV), the Southern Africa focussed metals exploration company, is pleased to announce the first assay results from the Hillside Prospect 3 gold project ("Prospect 3") in Matabeleland, southern Zimbabwe.
Highlights
· Hole NSDD001 was a scoping hole sited to target mineralisation below multiple sets of artisanal workings at Prospect 3.
· NSDD001 was drilled to a total depth of 301.40 m and intersected multiple shear zones hosting sets of anastomosing gold bearing quartz veins and associated sulphide mineralisation, totalling over 40m grading >0.5 g/t gold.
· Mineralisation starts at 12m below surface and may be open-pit mineable.
· Induced Polarisation (IP) anomalies suggest the shears extend to depth.
· Best results* in the hole include:
- 5.00 m @ 1.68 g/t gold from 97.00 m.
- 0.97 m @ 2.14 g/t gold from 148.00 m.
- 1.00 m @ 3.10 g/t gold from 156.00 m.
- And includes 11.90m @ 0.92g/t from 148m.
· Interpretation of recently re-processed geophysics including drone magnetic data and IP data suggests Prospect 3 and Prospect 2 may be located on opposite margins of a major regional deformation zone that extends 1.2km southeast to Prospect 1.
· The recently reported BRDD001 (Prospect 2) is located along the northern margin of the same deformation zone, and the width of the deformation zone between Prospect 2 and Prospect 3 is now estimated to be approximately 600m wide.
· Kavango is currently planning an extensive ground IP programme designed to assess the extent and continuity of the (chargeability & resistivity) anomalies already identified to understand the extents of the broad shear zone.
· Additional drilling will then be planned to evaluate what appears to be continuity between Prospects 1 and 2, over the interpreted strike length of 1,200m.
· Results provide confirmation of a likely extensive mineralised system.
*All quoted thicknesses are apparent down hole intersection thicknesses
Ben Turney, Chief Executive of Kavango Resources, commented:
"Results from Prospect 3 emphasise the potential size of the shear system at Hillside. Our interpretation of data from IP and drone magnetic surveys over the area further confirms the potential for a larger-scale gold target than we originally anticipated.
We now need to follow up with multi-element testing of the remaining pulps from the fire assays and more drilling to confirm the extent to which the 1,200m by 600m target area is mineralised with gold.
We are particularly encouraged by the presence of broad zones containing gold mineralisation in both holes NSDD001 and BRD001. This fits our idealised model for bulk-minable deposits, and we look forward to bringing the drill rig back to Hillside in June."
Prospect 3 Assay Results
Drill hole NSDD001 was originally designed to test the geology underneath current active artisanal workings at Prospect 3. The mineralised sections of the hole intersected veined and altered diorite and metasediments in broad shear zones hosting anastomosing quartz veins with associated pyrite, pyrrhotite, arsenopyrite, and chalcopyrite for a combined visually estimated total sulphide content ranging from 2 to 10%.
A table of significant results (>0.5g/t Au) is provided below. All the hole was assayed. Non-reported results are all below 0.5 g/t gold.

The Kavango technical team interprets these results as significant when considering the following qualifying factors:
- The sampling of half NQ drill core (47.6mm diameter) is thought to be indicative rather than representative given the probable nugget affect when assay values are compared with grades reported by artisanal miners.
- Previous rock grab sampling programmes conducted by historic exploration companies returned grades of up to 12g/t from the artisanal workings, in line with what the artisanal miners are verbally communicating.
- Historical machine excavated workings indicate the first ±5m of weathered material can be mined without blasting.
- The stamp mill operator reports that very little gold remains in the mill tailings from this prospect, indicating the gold is free milling.

Next Steps
Interpretation of satellite imagery together with recently re-processed geophysics including drone magnetic data and IP data suggests Prospect 3 and Prospect 2 may be located on opposite margins of a major regional deformation zone that extends 1.2km southeast to Prospect 1.
Hole NSDD001 was a scoping hole sited to target mineralisation below multiple sets of artisanal workings at Prospect 3 on the southern margin of the interpreted regional deformation zone. NSDD001 was drilled to a total depth of 301.40 m and intersected multiple shear zones hosting sets of anastomosing gold bearing quartz veins and associated sulphide mineralisation.
The recently reported hole BRDD001 (Prospect 2) is located along the northern margin of the same deformation zone, and the width of the deformation zone between Prospect 2 and Prospect 3 is now estimated to be approximately 600m wide.
Kavango is currently planning an extensive ground IP programme designed to assess the extent and continuity of the (chargeability & resistivity) anomalies already identified to further define and model the extents of the broad shear zone.
Additional drilling will then be planned to evaluate what appears to be continuity between Prospects 1 and 2, over the interpreted strike length of 1,200m.

As elsewhere at Hillside, although many of the intersections in this hole tend towards lower grades, the gold at Prospect 3 is understood from the artisanal workers to be coarse with an untested nugget effect. Artisanal miners report higher recovered grades from individual shears within a broader zone. Therefore, Kavango is considering a bulk sample exercise to relate drill core size recoveries and grades to a more realistic large bulk sample recovery and grade.
Kavango has completed a total of five holes across its Hillside prospects (see Table 1) of which it is awaiting assays for two holes.
