Botswana focussed metals exploration company Kavango Resources plc (LSE:KAV) is pleased to announce an important breakthrough in its use of Controlled-Source Audio Magnetotelluric (“CSAMT”) surveys as an exploration tool in the Kalahari Copper Belt (“KCB”).
Over the last 12 months Kavango has refined and calibrated its use of CSAMT, across its project portfolio. The Company has now completed a programme of CSAMT surveys on KCB prospecting licence PL082/2018 (announced >>> 12 October 2022).
Line 4A is the longest line of CSAMT on PL082/2018 and extended beyond the licence boundary to the southeast, onto ground that hosts the Kronos occurrence (the “Line 4A Survey”) with the permission of holder Sandfire Resources (ASX:SFR). As Kronos is known to lie at the D’Kar/Ngwako contact zone, Kavango’s objective was to use this occurrence as a calibration point of known geology. The goal is to confirm the D’Kar/Ngwako Pan contact signature in the CSAMT data and then extrapolate this onto PL082/2018. This formational contact is recognised as the primary regional control of copper/silver mineralisation across the KCB.
Initial results of inversions of the CSAMT data from the Line 4A Survey appear to provide high quality vertical resistivity sections that identify sedimentary strata with good resolution, down to 4000m depth. This far exceeds expectations. Previously, at the Company’s Kalahari Suture Zone and Ditau projects, Kavango had achieved detailed resolution of sedimentary strata down to roughly 1000m depth. As such, the Company believes it has achieved a significant breakthrough in its proprietary application of CSAMT technology in the KCB.
If drilling demonstrates that Kavango can accurately map the D’Kar/Ngwako Pan contact from surface, using CSAMT, the Company believes this should substantially enhance its exploration programme in the KCB.
Further updates will be made, as Kavango interprets and analyses inversions of data taken from the lines 3, 4A, 6A and 8 surveys. The Company intends to use these results to calibrate its future use of CSAMT and enhance the ongoing drill programme on licence PL082/2018, which is targeting copper/silver mineralisation.
Jeremy S. Brett, Senior Geophysicist at Kavango Resources, commented:
“CSAMT applied to the Kalahari Copper Belt is showing impressive promise as a geophysical tool to detect the primary bedding and secondary brittle controls that are well known to control mineralization in the belt.
This method provides the detection of structure in vertical section and meshes well with the regional folding and faulting that can be interpreted very well from aeromagnetic surveys.
The combination appears to be very powerful for exploration targeting, and Kavango hopes to prove this via diamond drilling.“
