Kavango Resources #KAV – KSZ Update & Expansion

Kavango Resources plc (LSE:KAV), the exploration company targeting the discovery of world-class mineral deposits in Botswana, is pleased to provide an update on its Kalahari Suture Zone (“KSZ”) Project.

Highlights:

Ø Update on Hole TA2DD002:

–    TA2DD002 is the second hole in the planned 6-hole programme currently being undertaken to investigate the Karoo gabbros in the Hukuntsi section of the KSZ.

–    Double shift drilling commenced on Friday 20 August

–    As of 1800 on Sunday 22 August the Hole was at 137m

–    Hole to test deeper Karoo gabbro “keel”, believed to be connected to the same gabbro encountered in Hole TA2DD001 (announced 16 August 2021), 1km to the west

–    Additional objective to test potential contact between Karoo and Proterozoic gabbros, which might represent a possible ‘feeder zone’

–    Hole to target western part of the same >1km geophysical anomaly (“Target A2”) drilled at Hole TA2DD001 (announced 20 April 2021)

–    Anticipated target depth of 400m to 450m (though preparations in place to drill up to 800m depending on contact with any gabbro encountered)

Ø Downhole electromagnetic (“EM”) survey Hole TA2DD001

–    Hole cased down to 393m from surface with steel casing, because of broken ground conditions

–    EM probe run by Spectral Geophysics Ltd (“Spectral) from 394m to 560m

–    According to analysis from Spectral, the A2 Time Domain Electromagnetic (“TDEM”) anomaly has been masked by the steel casing at 370m (i.e. the EM signal could not penetrate it)

–    Results inconclusive, but alternative options being evaluated for future hole design and possible downhole EM surveys

Ø Award of two new PLs in the KSZ covering a combined 1,258km2

–    Applied for in March 2021

–    PL081/2021 covers 987.8km2 across the eastern edge of the KSZ

–    PL080/2021 covers 270.4km2 and is contiguous with the Company’s existing PLs in the northern section of the KSZ

–    Both are 3-year licences, with the option of two 2-year renewal periods

–    £52,000 spending commitment in each PL over first 3 years

–    Kavango now holds 14 PLs in the KSZ, covering 8,751.7km2 

Ben Turney, Chief Executive Officer of Kavango Resources, commented:

“I’m very pleased at how quickly we’ve progressed to double shift drilling at Hole TA2DD002. We are now successfully moving through the gears of this drill campaign. The speed at which Equity Drilling/Mindea safely mobilised the rig to the new site is encouraging. 

Core recovery continues to be consistent and of the highest standard.

Meanwhile, the inconclusive results of the downhole EM survey of Hole TA2DD001 emphasise some of the engineering challenges we face. Keeping a deep hole open to depth in the KSZ is tough. It’s a credit to the drillers that Spectral got the EM probe from 394m depth to 560m, but the steel casing from surface to 393m meant readings could not be taken below this depth. We now believe the primary A2 Conductor is at 370m.

While the cores we extract are by far the most important data source, it would have been helpful to see the EM response of the A2 Conductor at its base. The steel casing will be left in place for the time being, until the downhole survey (to confirm the orientation of the hole) is completed. At this point we will seek to remove the casing and possibly run another, shallower downhole EM survey. However, given what we have experienced so far with the ground closing in on itself, we have modest expectations about whether this will be possible.

Whatever the case, the results of the assays and the whole rock geochemical analyses should provide us with the most valuable evidence we need to guide future exploration.

With the award of 1,258km2 of new prospecting licences and working capital over £3million, Kavango is well-positioned to take full advantage of its strategic hold over this highly prospective region.”

Note to Editors:

THE KALAHARI SUTURE ZONE

Kavango’s 100% subsidiary in Botswana, Kavango Minerals (Pty) Ltd, is the holder of 14 prospecting licences covering 8,751.7km2 of ground, including 12 licences over a significant portion of the 450km long KSZ magnetic anomaly in the southwest of the country along which Kavango is exploring for Copper-Nickel-PGM rich sulphide ore bodies. 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 World Class magmatic sulphide deposits such as those at Norilsk (Siberia) and Voisey’s Bay (Canada).

The Norilsk mining centre is about 2,800km northeast of Moscow and accounts for 90% of Russia’s nickel reserves, 55% of its copper and virtually all of its PGMs. Kavango’s licenses in the KSZ display a geological setting with distinct geological similarities to the magmatic sulphide deposits at Norilsk. Magma plumbing systems are a key feature of these deposits.

KSZ DEFINITIONS

EM Super Conductors: are bodies of highly conductive minerals such as graphite, magnetite and metal sulphides, which conduct electricity very rapidly provided the mineral grains are in contact with each other.

Gabbro/gabbroic: A coarse grained, medium to dark coloured rock, formed from the intrusion of mantle derived molten magma into the earth’s crust. Gabbroic rocks (or “gabbros”) are formed as the molten magma crystallizes and cools.

Gabbroic sills: Relatively thin, planar, horizontal bodies of solidified gabbroic magma that intruded into layers of sedimentary rock whilst still molten.

Karoo: The Karoo System covers 1.5 million km2 of the semi-desert region of Southern Africa. Rocks in this system formed 180-310 million years ago.

Massive sulphide: When a deposit consists almost entirely of sulphides it is termed “massive”. When it consists of grains or crystals of sulphide in a matrix of silicate minerals, it is termed “disseminated”.

Metal/Magmatic sulphide: Deposits of sulphide mineral concentrations in mafic and ultramafic rocks, derived from immiscible sulphide liquids. To view a video of how metal/magmatic sulphides form please visit –

https://twitter.com/KavangoRes/status/1316004057895645186?s=20

Norilsk Style: copper/nickel/PGE mineralisation associated with the intrusion into the upper parts of the Earth’s crust of mafic magma, which form magma chambers that sit below volcanic vents or fissures that extrude basaltic lava onto the surface (Hawaii is a possible modern equivalent). The Norilsk intrusions tend to have distinct morphologies, combining thin gabbro sills (wings) with deep keels (thought to be associated with feeder dykes) at the base.

Norilsk Model: a genetic geological model similar to that pertaining to the Norilsk/Talnakh deposits in Siberia. Traditionally, it was thought that, during emplacement, the magma incorporated sulphur rich country rock (e.g. coal measures) or evaporites into the melt, which allowed the molten magma to become sulphur saturated. The free sulphur would then combine, preferentially, with Cu/Ni/PGE metal ions to form metal sulphides, which, being heavy, tended to accumulate in traps or into the keel of the magma chamber. However, modern research suggests that the process might be more complex and may also involve changes of the chemical and physical properties of the magma during the introduction of new pulses of molten material from below. Such sudden changes may have caused rapid segregation of metal sulphides within and above the feeder dykes within the keel of the intrusion.

Sulphide mineralisation: If there is sufficient sulphur in the molten magma, it will tend to combine with metals (Cu, Zn, Ni, Co, Pb, PGEs etc.) to form metal sulphide complexes, which may coalesce to form massive sulphide deposits. If the melt is sulphide poor, the metals will be taken up into the silicate minerals that form as the magma cools and will not usually form economic deposits.

Kavango Resources #KAV – KSZ Hukuntsi – A2 Target Depth & Drilling Expansion

Kavango Resources plc (LSE:KAV), the exploration company targeting the discovery of world-class mineral deposits in Botswana, is pleased to announce successful completion of the first geological borehole in Target Area A (“Hole TA2DD001”) in the Hukuntsi (northern) section of the Company’s Kalahari Suture Zone (“KSZ”) Project. Hole TA2DD001 was drilled to a depth of 578m.

Following completion of Hole TA2DD001, the Company is pleased to announce it has signed an addendum to the current drill contract with Equity Drilling & Mindea Exploration and Drilling Services (Pty) (“Mindea”), which will now see the Company drill up to six geological holes in the current campaign in the KSZ (the “Campaign”).

Highlights

Ø Hole TA2DD001:

–    Drilled to a total depth of 578m

–    Drilling operations halted 10m below final contact with the Karoo gabbro

–    Primary objective fullfilled, with core samples successfully extracted throughout the entire hole

–    Visual inspection of cores confirms presence of sulphides

–    Coal seams encountered, confirming presence of potential source of sulphur for formation of magmatic sulphides

–    Core cutting expected to take 3-4 weeks to enable full sweep analysis of all core samples

–    Downhole electromagnetic (“EM”) survey to commence immediately

Ø Full sweep analysis of core samples to include:

–    Assay testing

–    Fire assay testing for gold and Platinum Group Elements (“PGEs”)

–    Whole rock geochemical analysis

–    Petrology analysis

Ø Further expansion of the Campaign:

–    Up to six boreholes now planned in the Campaign, targeting Target Areas A and C (the “A-C Corridor”) and Target Area B

–    Immediate mobilisation of rig to site of Hole TA2DD002 in Target Area A

–    On completion of Hole TA2DD002, rig to mobilise to Target Area B to drill the Company’s primary exploration target (“Target B1”, announced 2 July 2021)

Ø Final results to be announced on completion of the Campaign.

Ø Hole TA2DD002:

–    Located 1km west of Hole TA2DD001

–    Hole to test deeper Karoo gabbro “keel” (est. up to 800m), believed to be connected to the same gabbro encountered at Hole TA2DD001

–    Additional objective is to test potential contact between Karoo and Proterozoic gabbros, which might represent a possible volcanic ‘feeder’ zone

–    Hole to target the same >1km geophysical anomaly drilled at Hole TA2DD001 (announced 20 April 2021) 

Ben Turney, Chief Executive Officer of Kavango Resources, commented:

“Our strategic objective in the KSZ in 2021 is ‘proof of concept’. If we can achieve this, the prize on offer is considerable.

The successful completion of Hole TA2DD001 will hopefully prove to be a significant step forward in that direction.

This is the deepest hole Kavango has drilled and I would like to thank Equity Drilling and Mindea for the exceptional engineering effort they have accomplished on our behalf. The quality of core samples is superb and provides us with exactly the raw materials we need to perform detailed rock analysis to test the KSZ’s potential to host magmatic sulphide ore bodies.

Although we must remain measured, we are sufficiently encouraged by what we have seen so far geologically and operationally, to expand our current drill programme in the KSZ to up to six holes.

The drill rig is mobilising 1,000m from its current location to test a deeper ‘Norilsk-style keel’ formation, on the western edge of the A2 conductive anomaly. This next hole should really take us into the guts of the KSZ and will hopefully provide us with the most valuable geological data recovered yet in this region.

Following completion of drilling operations in Target Area A, we will then move the drill rig to Target B1. This is our current primary exploration target. The conductive anomaly is approximately 475m by 550m, with a verified conductance reading of 8,200Siemens.

Once we have completed drilling Target Area B our intention is to bring the rig back to Target Area C, to test the potential of the ‘A-C Corridor’.

We now move forward with confidence to the next hole.”

Operational Update

Drilling operations at Hole TA2DD001 commenced on 21 July 2021 and finished on 15 August 2021. Mindea, the drill rig operator, drilled to a total depth of 578m. The original target depth was 500m, but contact with the Karoo gabbro lasted until 568m.

The Company chose to drill a further 10m below this formation before halting operations to allow for preparation of an immediate downhole EM survey by Spectral Geophysics (“Spectral”). Spectral expects to complete the downhole EM survey over the coming days.

Mindea successfully retrieved high quality core samples throughout Hole TA2DD001 in 3-meter runs.  These samples are currently being cut, ready for shipment for laboratory analysis. The Company intends to test all gabbroic samples collected and plans to release full results on completion of the Campaign.

Kavango is confident that all of the gabbro samples collected from Hole TA2DD001 are Karoo-age. The presence of Karoo sediments above and below the gabbro samples appears to confirm the stratigraphic relationship, with clearly defined contacts at the chilled margins.

Laboratory testing will include standard assay testing for base metals, fire assay testing for gold and PGEs, whole rock geochemical analysis and petrology analysis of thin sections.

Mindea will now mobilise the drill rig to the site for Hole TA2DD002, 1,000m from its current location.

Hole TA2DD002 targets a deeper ‘Norilsk-style keel’ Karoo gabbro, as well as the western edge of the A2 conductor (targeted by Hole TA2DD001). Kavango expects to drill up to 800m at Hole TA2DD002, with the goal of testing the potential contact between the Karoo and Proterozoic gabbros. Kavango believes this could represent a possible Karoo-age feeder zone.

The Company will make a further announcement when drilling operations commence at Hole TA2DD002.

Following completion of Hole TA2DD002, Mindea will then move the rig to Target Area B and is expected to drill two holes here. Target Area B is roughly 16km from Target Area A.

The first of geological hole in Target Area B will target the conductive anomaly of the Target B1 (announced 02 July 2021). Target B1 is 475m by 550m, with a conductance of approximately 8,200Siemens. The decay constant is estimated to be in excess of 350ms. This is currently Kavango’s primary exploration target in the KSZ.

Kavango Resources #KAV – KSZ Hukuntsi Proof of Concept drilling commences

Kavango Resources plc (LSE:KAV), the exploration company targeting the discovery of world-class mineral deposits in Botswana, is pleased to announce that drilling has commenced on Target A2 (“A2”) in the northern (Hukuntsi) section of the Kalahari Suture Zone (“KSZ”).

The goal of this geological borehole is to retrieve core samples from the bottom of the “Norilsk style keel” at A2. The Company’s hope is that assay and other analysis of said rock samples will result in “proof of concept” that the Karoo-age gabbros in the KSZ have the potential to host magmatic sulphide ore bodies.

The target depth at A2 is currently estimated to be 500m.

On completion of drilling operations at A2, Kavango’s drill partners (Equity Drilling Ltd and Mindea Exploration and Drilling Services (Pty) Ltd) will immediately mobilise the rig to Target C1 (“C1”), 11km away. The Company believes A2 and C1 are on the same geological corridor.

Following completion of drilling at C1, the rig will then mobilise to Target B1 (“B1”). Plans for this hole are currently being finalised and the Company will provide an update in due course.

Kavango estimates A2’s properties are:

–    The target is 1km in length and is open along strike

–    It extends between 250m to 700m below surface and is gently dipping

–    A 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 (announced 8 September 2020)

Ben Turney, Chief Executive Officer of Kavango Resources, commented:

“Years of hard work and dedication have brought us to this point. We could now be on the cusp of achieving something truly great. It can be difficult to communicate in an RNS quite how much effort and creative energy goes into a project like the Kalahari Suture Zone.

The going hasn’t been easy, but everyone has stuck with it, often making great sacrifices along the way. I am immensely proud of our team. If anyone has ever deserved success in field exploration, it is the people who have given so much to Kavango.

With the drill bit now turning at A2, we should soon hopefully become the first company ever to retrieve core samples from the bottom of a Karoo-age gabbro in the region.

We have great confidence in Equity Drilling and Mindea to drill boreholes that will enable us to realise this ambition. The focussed planning that has gone into our drill campaign has been exceptional. Safety and security standards are international quality and the engineering design is robust.

Obviously this is a business where there can be no guarantees, but everything possible has been done to minimise our operational risks. The next few months promise to be incredibly exciting.”

Primary objective of the current KSZ drill campaign

Kavango’s primary objective is to become the first company ever to retrieve drill core from the bottom of the “keels” of the Karoo-age gabbros in the KSZ. The Company anticipates that drill-core from these holes will provide firm physical evidence of the KSZ’s potential to host ‘Norilsk-style’ metal sulphide deposits.

About Mindea

Mindea Exploration and Drilling Services (Pty) LTD was formed in September 2019 by Equity Drilling Limited and Maureen Mokgaotsane (Geologist), Sebanka Lobatlamang (Geologist) and Eddie Babuseng (Attorney at Law) to provide complete exploration solutions to its clients in Botswana.

Mindea is currently operated under the Botswana Citizen Economic Empowerment Policy and is owned 51% by local shareholders and 49% by Equity Drilling. Over the coming years it is expected that Botswana nationals will wholly own Mindea, with Equity Drilling continuing to provide strategic and technical support.

Mindea operates to strict international safety standards and deploys the latest equipment to its projects. Mindea is rigorous in its planning and site preparation.

Reflecting the quality of its operations, Mindea has recently been awarded a 3-year contract by Debswana to drill various national projects in Botswana. In addition to this, Mindea is a regular drill contractor for DeBeers.

About Equity Drilling

The owners of Equity Drilling are extremely experienced drill operators, with extensive experience of successfully working on technically challenging projects across Africa.

Equity Drilling established Africa’s first Drilling School in Botswana, the Africa Mining and Drilling Institute (“AMDI “)

AMDI is Botswana Qualifications Authority (BQA) certified, which offers internationally recognised certification to all students wishing to be taught exploration drilling. AMDI has an exclusive working relationship agreement in place with the Australian Drilling Industry Association (the “ADIA”) and offer the ADIA’s DICAT curriculum with a strong emphasis on safety in the workplace.

AMDI also offers funds the delivery of pre-industry courses to students from local communities, who have had no previous work experience. This course prepares students for the work place and making them eligible for placement into the industry on graduation. Mindea’s own labour resources have been drawn from these pre-industry course graduates

About Target A2

Kavango estimates Target A2’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

Kavango Resources #KAV – KSZ Hukuntsi TDEM conductor B1 identified

Kavango Resources plc (LSE:KAV), the exploration company targeting the discovery of world-class mineral deposits in Botswana, is pleased to announce the identification of an electro-magnetic (“EM”) anomaly in Target Area B in the Hukuntsi (northern) section of the Company’s Kalahari Suture Zone (“KSZ”) Project.

Designated Target B1 (“B1”), the conductive anomaly is 475m by 550m with a conductance of approximately 8,200Siemens. The decay constant is estimated to be in excess of 350ms.

Target Area B is roughly 12km from Target C1 (announced on 15 June 2021). Kavango believes Target Area B is in a separate, distinct geological setting to the A-C corridor.

The Company is in discussion with Equity Drilling & Mindea Exploration and Drilling Services (Pty) to extend the current drill contract to include drilling a 550m borehole into B1, to retrieve core from the bottom of the “Norilsk-style keel” that underneath it.

The Company has also engaged its strategic partner Spectral Geophysics to conduct two more Time Domain Electromagnetic (“TDEM”) surveys in Target Area B.

Ben Turney, Chief Executive Officer of Kavango Resources, commented:

“B1 appears to be the best conductor we have identified so far. The 8,200Siemens reading is particularly encouraging. With a rig already mobilising in Hukuntsi, we plan to drill this target as soon as the two boreholes are complete in the A-C corridor.”

THE KALAHARI SUTURE ZONE

Kavango’s 100% subsidiary in Botswana, Kavango Minerals (Pty) Ltd, is the holder of 14 prospecting licences covering 7,573.1km2 of ground, including 12 licences over a significant portion of the 450km long KSZ magnetic anomaly in the southwest of the country along which Kavango is exploring for Copper-Nickel-PGM rich sulphide ore bodies. 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 World Class magmatic sulphide deposits such as those at Norilsk (Siberia) and Voisey’s Bay (Canada).

The Norilsk mining centre is about 2,800km northeast of Moscow and accounts for 90% of Russia’s nickel reserves, 55% of its copper and virtually all of its PGMs. Kavango’s licenses in the KSZ display a geological setting with distinct geological similarities to the magmatic sulphide deposits at Norilsk. Magma plumbing systems are a key feature of these deposits.

KSZ DEFINITIONS

EM Super Conductors: are bodies of highly conductive minerals such as graphite, magnetite and metal sulphides, which conduct electricity very rapidly provided the mineral grains are in contact with each other.

Gabbro/gabbroic: A coarse grained, medium to dark coloured rock, formed from the intrusion of mantle derived molten magma into the earth’s crust. Gabbroic rocks (or “gabbros”) are formed as the molten magma crystallizes and cools.

Gabbroic sills: Relatively thin, planar, horizontal bodies of solidified gabbroic magma that intruded into layers of sedimentary rock whilst still molten.

Karoo: The Karoo System covers 1.5 million km2 of the semi-desert region of Southern Africa. Rocks in this system formed 180-310 million years ago.

Massive sulphide: When a deposit consists almost entirely of sulphides it is termed “massive”. When it consists of grains or crystals of sulphide in a matrix of silicate minerals, it is termed “disseminated”.

Metal/Magmatic sulphide: Deposits of sulphide mineral concentrations in mafic and ultramafic rocks, derived from immiscible sulphide liquids. To view a video of how metal/magmatic sulphides form please visit –

Norilsk Style: copper/nickel/PGE mineralisation associated with the intrusion into the upper parts of the Earth’s crust of mafic magma, which form magma chambers that sit below volcanic vents or fissures that extrude basaltic lava onto the surface (Hawaii is a possible modern equivalent). The Norilsk intrusions tend to have distinct morphologies, combining thin gabbro sills (wings) with deep keels (thought to be associated with feeder dykes) at the base.

Norilsk Model:   a genetic geological model similar to that pertaining to the Norilsk/Talnakh deposits in Siberia. Traditionally, it was thought that, during emplacement, the magma incorporated sulphur rich country rock (e.g. coal measures) or evaporites into the melt, which allowed the molten magma to become sulphur saturated. The free sulphur would then combine, preferentially, with Cu/Ni/PGE metal ions to form metal sulphides, which, being heavy, tended to accumulate in traps or into the keel of the magma chamber. However, modern research suggests that the process might be more complex and may also involve changes of the chemical and physical properties of the magma during the introduction of new pulses of molten material from below. Such sudden changes may have caused rapid segregation of metal sulphides within and above the feeder dykes within the keel of the intrusion.

Sulphide mineralisation: If there is sufficient sulphur in the molten magma, it will tend to combine with metals (Cu, Zn, Ni, Co, Pb, PGEs etc.) to form metal sulphide complexes, which may coalesce to form massive sulphide deposits. If the melt is sulphide poor, the metals will be taken up into the silicate minerals that form as the magma cools and will not usually form economic deposits.

Kavango Resources Plc (KAV) – KSZ Hukuntsi – TDEM conductor C1 identified

KSZ Hukuntsi – TDEM conductor C1 identified

Kavango Resources plc (LSE:KAV), the exploration company targeting the discovery of world-class mineral deposits in Botswana, is pleased to announce the identification of an electro-magnetic (EM) anomaly in Target Area C in the Hukuntsi (northern) section of the Company’s Kalahari Suture Zone (“KSZ”) Project.

Designated Target C1 (“C1”), the conductive anomaly is located 11km from Target A2 (“A2”), which was first announced on 20 April 2020.

C1 and A2 appear to lie within the same geological corridor. The Company now plans to drill a minimum of one hole in A2 and a minimum of one hole in C1. Drilling is to commence at the end of June.

Both A2 and C1 lie in ‘Norilsk-style’ gabbro keels. The primary objective of both holes is to recover drill core from the bottom of the keels for further analysis to test the system’s potential to host major metal sulphide deposits.

 

Highlights

  • Target C1
    • 11km NE of Target A2
    • Kavango believes A2 and C1 lie in the same geological corridor of Karoo-age gabbro, which is open in both directions
    • The conductor is 1,200m by 1,600m and sits at the bottom of a keel as defined by the Company’s 3D Geological Model
    • 530m depth from surface to centre of the conductor
    • The decay constant is ~360msec
    • Conductance of 2,500 Siemens
  • Drill plan:
    • Drill operator is Mindea Exploration and Drilling Services (Pty) (“Mindea”)
    • Mindea to set up camp between Targets A2 & C1
    • Drilling at A2 to commence in June
    • Drilling to commence at C1 in July
    • Kavango to pay <half the total drill cost to Mindea in cash (c.£70,000), with remaining fees payable in shares
    • Potential to increase scope of drilling, once rig is on site and pending further data analysis
    • Extensive assaying and downhole geophysics planned on all boreholes

 

Michael Foster, Chief Executive Officer of Kavango Resources, commented:

“The ‘Norilsk Model’ for metal sulphide systems suggests deposits originally formed in clusters. In this context, it is encouraging that C1 is located relatively close to A2. We believe both targets lie potentially within the same geological corridor of Karoo gabbro.

If drilling validates our interpretation of the data, this could prove to be a significant development in our attempts to unlock the Kalahari Suture Zone.

The fact that C1 shares a number of highly similar characteristics with A2 is very encouraging. Like A2, C1 is in an ideal geological setting (at the bottom of a “keel”), is nearly 2km2 in size, has a conductance of 2,500 Siemens and a decay constant of ~360msec.

We look forward to retrieving core from both targets in the coming months.”

 

Background

Over the last three years, Kavango has conducted extensive geophysical surveys over Karoo-age gabbros at Hukuntsi using airborne and ground-based based technology. In 2019 Kavango completed a successful orientation drill programme, data from which helped augment the Company’s extensive 3D Magnetic Model of the region’s subsurface geology (announced 8 September 2020).

On 30 November 2020 Kavango released results from its analysis of the 3D Magnetic Model, which revealed close similarities between the gabbroic rock formations in the KSZ and those at the Norilsk mining centre, in northern Russia.

In December that year, the Company initiated the first ground-based Time Domain Electromagnetic (TDEM) survey of the KSZ. This was the first time this powerful remote sensing technology had been used on the KSZ. Kavango subsequently secured a strategic partnership with the TDEM operator, Spectral Geophysics Ltd, to accelerate and broaden the TDEM programme.

On 20 April 2021 and 5 May 2021, Kavango released details of the results from the second TDEM survey, which defined Target A2.

On 10 June 2021, Kavango announced plans to drill two holes in the KSZ. The drill contractor is Mindea Exploration and Drilling Services (Pty), who has agreed to receive >half its fees in equity from Kavango.

About Target A2

Kavango estimates Target A2’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)

About Target C1

Kavango estimates Target C1’s properties are:

–    1,200m by 1,600m in size

–    530m depth to centre of the conductor

–    Decay constant of approximately 360msec and conductance of approximately 2,500 Siemens

–    Located in the right geological setting, at the bottom of a “keel” in the gabbroic intrusion, 11km away from A2 (potentially in the same geological corridor of Karoo-gabbro)
