Botswana focussed metals exploration company Kavango Resources plc (LSE:KAV) (“Kavango”) is pleased to announce encouraging initial results from the Controlled-Source Audio Magnetotelluric (“CSAMT”) surveys conducted over PL082/2018 in the Kalahari Copper Belt (“KCB”).
Kavango is the first company on the KCB to deploy CSAMT in this way. If validated by the Company’s current drill programme on PL082/2018, Kavango’s field application, inversion and interpretation techniques could prove to be a highly powerful exploration tool in this region.
– Results of inversions of the CSAMT data on lines 8 and 6a encompass:
– High quality data down to 4km depth, far exceeding expectations
– High contrast resistivity sections that clearly delineate major folding and faulting
– Current interpretation highlights a very sharp steeply dipping geological structure/deformation zone within Kavango’s PL082/2018 licence area, against which steeply folded lithologies sit:
– This is interpreted as a faulted and brecciated margin
– CSAMT inversions suggest that this structure extends to 4km depth
– Such deep seated structures are thought to serve as pathways for fluid flow and mineral s mobilisation, a key component of mineralising systems in the KCB
– On both CSAMT sections processed to date, this significant deformation zone is interpreted to be coincident with the Northern Zone Soil copper anomaly and a significant airborne electromagnetic (“AEM”) conductor
– KCBRC001, the current hole being drilled on PL082/2018, is designed to test a different CSAMT signature that is interpreted as a main stratigraphic contact, and directly targets the highest soil copper values (118.8ppm copper; pXRF values) recorded on the licence to date
– Additional CSAMT work is planned to improve interpretation of the geology and structure of PL082/2018 by collecting closer spaced data using an even closer station spacing than the current 50m, thereby further increasing resolution.
– Current planned drillholes will be used to calibrate the CSAMT inversions and interpretation with the geology and structures.
Ben Turney, Chief Executive Officer of Kavango Resources, commented:
“One of Kavango’s competitive edges is our commitment to trialling modern remote sensing technology across our portfolio. The outcome is often unpredictable, but the upside can be significant.
From what we’ve seen of the results so far from our CSAMT surveys over PL082, this technology has potential to become transformational for exploration in the Kalahari Copper Belt.
Mapping the crucial Ngwako Pan/D’kar Formation contact and structural fluid conduits is key to discovering copper/silver deposits. With the drill rig in the field, we now have a perfect opportunity to test our geophysics against physical geology.”
