KSZ Update
Further to the announcement on 20 April 2021, Spectral has completed a third Time Domain Electromagnetic ("TDEM") survey in Target Area A ("Survey A3"). This survey was designed to corroborate the existence of the large-scale conductive anomaly previously identified. Spectral also deployed an upgraded configuration of its equipment, which has proved to be successful.
TDEM surveys can be used to identify super electromagnetic ("EM") conductors at depth, within highly complex geological environments such as the KSZ. Spectral Geophysics is a highly experienced and effective operator of TDEM technology currently being employed on the project.
Data from Survey A3 has now been successfully processed and interpreted. The data further confirms the existence of the previously identified conductive anomaly and that it has a conductance of ~3000 Siemens. Kavango now estimates the anomaly's properties are:
- 1km length, which is open along strike
- Extends between 250m to 700m below surface and is gently dipping
- Decay constant of approximately 340msec and conductance of approximately 3000 Siemens, readings which Kavango management considers are consistent with nickel sulphide deposits elsewhere in the world
- Located in the right geological setting, at the bottom of a "keel" in the gabbroic intrusion, according to the Company's Magnetic 3D-Model (8 September 2020)
As the results come in from Kavango's extensive TDEM surveying programme and are processed and interpreted, the Company expects to start planning a drilling programme. The exact timing and extent of such a programme remains to be determined, but it is currently considered likely that it will include drilling inclined holes of up to 450m through the conductive target at A2 that will aim to intercept the conductor at roughly 400m.
Kavango has prepared an explanatory video, which presents the geophysical model of the conductive target at A2, for shareholders to view on the Company's website. The video is accessible via the link below:
