KAVANGO RESOURCES PLC
("Kavango" or "the Company")
PHASE 2 OF AIRBORNE EM SURVEY MOBILISED IN BOTSWANA
Kavango Resources plc (LSE: KAV), the exploration group listed
on the Standard List segment of the main market of the London Stock
Exchange and targeting the discovery of world class mineral
deposits in Botswana, is pleased to announce that Phase 2 of the
airborne electromagnetic (AEM) survey over the Kalahari Suture Zone
(KSZ) prospecting licences has been mobilised, with anticipated
start of flying later this month.
HIGHLIGHTS:
-- The Company has contracted the services of SkyTEM, a leading
airborne geophysical survey company offering the acquisition and
advanced processing of the highest quality helicopter-borne
electromagnetic data, to carry out Phase 2 of a detailed AEM survey
over Kavango's KSZ licences.
-- The AEM survey will cover up to 2,062 line-kilometres in the Hukuntsi area of Botswana.
-- The survey will be flown with SkyTEM's innovative new
generation 312 HP (High Power) technology for deep exploration.
This High Power system, with a peak moment up to 1,000,000 NIA, is
optimized to provide an exceptional depth of investigation due to
the high moment (HM) mode with high current and low base frequency
of 12.5 Hz. This system has only been on the market since 2017 and
therefore, represents a major advance in AEM systems.
-- The SkyTEM survey is planned to begin in late January 2019 and take approximately 4-6 weeks.
Michael Foster, Chief Executive Officer of Kavango,
commented:
"We are pleased to be able to announce the start of Phase 2 of
the AEM Survey. SkyTEM's new High Power system will allow us to
investigate the potential for Cu-Ni-PGE rich sulphide orebodies at
much deeper levels and with greater resolution than older
systems.
The greater depth penetration of the new SkyTEM312 HP (High
Power) system should give Kavango much better discrimination in the
prioritization of target conductors.
Follow up of EM conductors will be directed only towards those
conductors that lie below the Kalahari sequences whilst near
surface conductors (clays, shales etc) can be safely ignored. This
will accelerate the follow-up program by allowing us to concentrate
only on the most prospective conductors and should represent a
major breakthrough in the Company's exploration strategy."
Notes for Editors:
Kavango's 100% subsidiary in Botswana, Kavango Minerals (Pty)
Ltd, is the holder of 15 prospecting licences covering 9,231 km(2)
of ground, including most of the 450km long KSZ magnetic anomaly in
the southwest of the country along which Kavango is exploring for
Cu-Ni-PGE rich sulphide orebodies. This large area, which is
entirely covered by Cretaceous and post-Cretaceous Kalahari
sediments, has not previously been explored using modern
techniques.
The area covered by Kavango's KSZ licences displays a geological
setting with distinct similarities to that hosting the Norilsk
Ni-Cu-PGE orebodies in Siberia.
The newly developed SkyTEM312 HP (High Power) system
(https://skytem.com/wp-content/uploads/SkyTEM312-HP.pdf) will be
used to identify conductors at depth and distinguish between near
surface Kalahari Group conductors and the deeper Karoo conductors
which are Kavango's principal targets. These will be further
evaluated by Induced Polarisation (IP) and Controlled Source
Audio-frequency Magneto-Tellurics (CSAMT)* ground based geophysical
surveys and geochemical soil analysis with particular emphasis on
the zinc pathfinder**. Geophysical techniques such as IP penetrate
below the over-lying Kalahari cover and help to identify the exact
location of the conductive body. 3D computer modelling of the
conductor further defines the location and physical characteristics
of the conductor ahead of testing by drill intersection.
*Massive sulphide (base metal) deposits can be detected by CSAMT
because they conduct electricity easily (conductors) as opposed to
silicate wall rocks (resistive).
**Kavango geologists have developed a high-resolution soil
sampling technique to detect ultra-fine metal particles which have
been transported in solution from considerable depths of burial to
the surface by capillary action and transpiration. Evaporation
leaves the metal ions as accumulations within a surface "duricrust"
which is then sampled and analysed. Zinc, which is the most mobile
of the base metal elements (i.e. goes into solution easily) acts as
a pathfinder to mineralization at depth.
