Okavango includes tenements immediately along strike from Cupric Canyon’s Zone 5 and Zone 5N copper deposits. KML has utilised high resolution magnetics and AEM surveys to map out target areas for exploration drilling. Of the six core holes drilled in 2019 as an initial test of these targets, KML has reported that five holes intersected the mineralised D’Kar/Ngwako Pan contact. The Okavango tenements are a mix of 100%-owned and JV holdings.
The OCP is located in the central portion of the Kalahari Copper Belt and is immediately along strike, on the perceived central structural corridor, to the east of the Cupric’s Zone 5 Deposit and Sandfire’s T3 Project. Historical soil sampling (13,281 samples) confirmed extensive copper anomalism which was interpreted to derive from a possible REDOX contact within project area.
Similarly at Ngami, KML has reported that early stage exploration drilling based on magnetic and AEM survey interpretation has resulted in successful intercepts of the copper mineralised D’Kar/Ngwako Pan contact.
Work completed to date includes high resolution magnetic geophysics, soil sampling, 2,000m of drilling and a regional airborne electromagnetic (“AEM”) survey. Soil sampling has confirmed the existence of anomalous copper, which may be related to an underlying interpreted REDOX contact (Figure 6).
Drilling has returned positive results with Cu mineralisation associated with hydrothermal veining structures intersected in several holes.
Zone 5 (91mt@ 2.13% Cu & 22g/t Ag)
Zone 5N (17mt@ 2.27% Cu & 43.4g/t Ag)
Zone 6 (16.7mt@ 0.9% Cu & 4g/t Ag)
Zeta (25mt@ 2.19% Cu & 44.6g/t Ag)
The OCP 2019 Drilling Programme consisted six holes (OCP01 to OCP06), 1,656m drilled, which successfully confirmed the presence of DKF-NPF stratigraphy and the DKF-NPF REDOX contact that hosts prospective Cu-Ag mineralisation.
Recent airborne electromagnetic surveys have identified a number of ‘dome’ targets analogous to Sandfire’s T3 deposit. Re-interpretation of high-resolution magnetic data supported the possibility for mineralisation occurring in fold hinge zones with potential ‘dome’ targets. Follow-up regional airborne electromagnetics confirmed a number of compelling targets which are being investigated by a second phase of high-resolution electromagnetic geophysics.
