PRESS RELEASE
9 February 2026
KAVANGO RESOURCES PLC
("Kavango" or "the Company")
Preliminary Mineral Resource Estimate for Bill's Luck Gold Mine
Kavango Resources plc (LSE:KAV, VFEX:KAV.VX), the Southern Africa focused
metals exploration and gold production company, is pleased to announce the
maiden Mineral Resource Estimate for Bill's Luck Gold Mine ("Bill's Luck")
within the Hillside Gold Project ("Hillside"), Zimbabwe.
Highlights
· A preliminary JORC-compliant Mineral Resource Estimate (the "JORC
MRE") totalling 33,900 ounces of gold ("oz/Au") at 2.68 grammes per tonne
("g/t") is declared at Bill's Luck, comprised of:
o 2,600 oz/Au at 3.3 g/t in the measured category.
o 13,400 oz/Au at 2.7 g/t in the indicated category.
o 18,000 oz/Au at 2.6 g/t in the inferred category.
· The resource is reported at a cut-off grade of 0.5 g/t, based on
reasonable prospects for economic extraction at a gold price of $3,000/oz.
· This brings the total JORC-compliant gold resource within Hillside to
52,900 oz, building on 19,000 oz at Kavango's Nightshift project, announced
October 2025
(https://polaris.brighterir.com/public/kavango_resources_plc/news/rns/story/w009mlw)
.
· Bill's Luck is a historic, operating gold mine that Kavango is
redeveloping and re-equipping, and will support its soon-to-be commissioned 50
tonnes per day ("tpd") Carbon-In-Pulp ("CIP") plant.
· Kavango considers Hillside to be a mineralised system with
significant upside potential. The Bill's Luck deposit remains open at depth
and along strike, and Kavango looks forward to further upgrading the resource
through targeted drilling from underground and from surface.
· Kavango's technical team will now use the JORC MRE to de-risk and
accelerate development and gold production from Bill's Luck, ensuring low
dilution through appropriate mining methods.
· The team is also working on the economic feasibility of small scale,
trial mining pits in the unconsolidated sediments overlying the Nightshift
project, to further boost gold production in a historically high gold price
environment.
Peter Wynter Bee, Interim Chief Executive Officer of Kavango, commented:
"At Kavango we have always believed Bill's Luck Gold Mine has the potential to
become a meaningful, long-term contributor to gold production at Hillside.
Having been mined intermittently for over a century, today's announcement
represents the first step in modernising operations at Bill's Luck with the
declaration of its maiden JORC-compliant MRE.
"The delineation of this resource paves the way for a process of longer term
mine planning and efficient gold extraction to unlock further value. We are
well-positioned to ramp up production and capitalise on the strong gold price
environment as our CIP plant comes online."
Preliminary Resource Modelling at Bill's Luck
Bill's Luck Mine is situated within the Hillside Gold Project. Originally
mined between 1916 and 1950, the Bill's Luck Mine produced around 17,000 oz/Au
at an average grade of 7.7 g/t. Since then, only limited and informal
community mining activity and small-scale retreatment have taken place. At
present, Kavango is focusing on development of the Bill's Luck underground
mine ahead of the commissioning of its 50 tpd pilot CIP plant.
Gold mineralisation at Bill's Luck is structurally and hydrothermally
controlled, predominantly occurring within and along the margins of these
shear zones. Alteration is characterised by quartz-sericite-chlorite
assemblages with disseminated sulphides, often vein-controlled and associated
with syntectonic quartz-sulphide veins.
Zones of higher vein density and alteration coincide with areas of stronger
deformation, with quartz boudinage, pressure shadows, and mylonitic veins
serving as key mineral traps. Late stage mineralised veins also crosscut the
earlier mylonitic fabric, indicating prolonged and possibly multi-phase
mineralisation.
This structural complexity, combined with the presence of high-strain domains,
linking shear structures, and favourable vein-hosting environments, makes the
Bill's Luck area a high-potential target for structurally-controlled gold
exploration within a dextral transpressional regime.
The resource drilling programme at Bill's Luck was designed to establish a
maiden MRE to support and inform future mine planning and scheduling, while
also unlocking the full value for what is increasingly believed to be a
significant mineralised system at Bill's Luck.
The MRE utilises all data available as of 30 January 2026, a total 6721 metres
("m") of surface diamond drilling, and 4646 m of surface reverse circulation
drilling conducted since Kavango's acquisition of the Hillside project.
The drill programme has intersected the currently mined "Main Reef", as
expected, but has also confirmed the presence of an additional "reef"
structure adjacent to and parallel with the "Main Reef" that is also
mineralised. The drilling also tested and intersected further "reefs" in both
the hanging wall and footwall.
Highlights from the JORC MRE
Geological Data
The drilling and trenching geological, geotechnical, structural and sampling
information are stored in a well-structured database system, where all
documentation is readily available for validation and review.
The JORC MRE is based on the following data:
· 24 Surface diamond boreholes (6721 m).
· 35 Surface reverse circulation boreholes (4646 m).
· Geotechnical boreholes (537.7 m) - unsampled.
· 16 Percussion boreholes (1397 m) - void delineation.
· 30 Underground Diamond boreholes (1703.58 m).
· Underground mapping and sampling of exposure (192 sample channels).
· Sectional interpretation of borehole intersections using
lithological, structural and sampling data.
All available data on 30 January 2026 was used in the Mineral Resource
Estimate.
Assay Quality Control
A comprehensive assay quality control programme is in place, which complies
with industry best practice. The results of the Quality Assurance / Quality
Control programme ("QA/QC") were assessed with the following conclusions:
· Negligible sample contamination is taking place based on the results
of blank material inserted in the sample batches.
· The accuracy of the results is acceptable, based on the results of
the certified reference material inserted in the sample batches.
· Precision of the results is lower than would be expected. This is
ascribed to the low grade and nuggety nature of the gold mineralisation, and
recommendations will be made to improve this.
Geological Interpretation
Analysis of the results from regional traverse mapping, exploration-scale
structural mapping and detailed core-logging showed that the gold
mineralisation at the Hillside prospects associates with shear zones that have
acted as fluid conduits and controlled the alteration, vein density and gold
mineralisation.
At Bill's Luck, gold mineralisation occurs in steeply NNE-dipping anastomosing
shear zones, and the intrusive contact between the metasedimentary rocks and
the Balmoral mafic intrusives.
In the shear zones, gold is associated with smoky quartz veins that parallel
shear zone foliation as well as the alteration halos of the veins. Gold also
occurs in the contact zone between the metasedimentary rocks and the Balmoral
mafic intrusives, where gold is hosted by smoky veins as well as the
metasedimentary and the mafic rocks adjacent to the veins.
In both cases, gold-bearing veins occasionally carry sulphides (pyrite and
chalcopyrite). Alteration types related to gold mineralisation are mostly
silicification, sericitization and occasional chloritization. Gold deposition
broadly synchronises with the early stages of the main shearing event.
The shear zones exposed and sampled underground, and intersected in boreholes
were modelled in three dimensions, using geological description and structural
measurements to guide the correlation or ore zones.
The main ore zone appears to comprise three en-echelon quartz vein filled
shears, offset from each other by 10s of metres.
A number of sub parallel hanging and footwall zones exist, with generally
lower grade gold mineralisation, associated with the metasedimentary contacts
in some cases.
Deposit Dimensions and Spatial Control
Borehole positions are surveyed by differential GPS by a qualified surveyor.
Down hole surveys are undertaken. A high-resolution drone survey provides
topographical control. The current underground workings have been surveyed by
a qualified surveyor. Historical workings a have been surveyed by drone borne
LIDAR where possible.
The deposit comprises set of shear zones striking WNW-ESE and dipping at 70-80
degrees to the NNE, with a total strike of 450 m. The mineralised shears
outcrop on surface, but have been extensively mined down to approximately 50 m
below surface. The deposit has been shown to extend a further 150 m to depth,
with the deepest intersection at 200 m below surface.
Estimation and Modelling Techniques
Estimation was done using Surpac Vision version 6.1.3 software.
A block model with parent block sizes of 12.5 m x 12.5 m x 0.8 m (y: strike,
z: height, x: width) was created, and sub-blocked to 1.5 m x 1.5 m x 0.1 m to
represent the volume as accurately as possible.
The individual shear zones were used as discrete geological domains, and each
domain was estimated separately, using only the samples from within that zone,
to prevent grade smearing between mineralised zones. The maximum projection
distance used was 25 m.
Block grade estimation was done using multiple indicator kriging, a non-linear
geostatistical method for estimating resources in deposits with highly skewed
and mixed-grade distributions, often used in gold deposits.
Block estimates were validated visually on plan and section by comparing them
to the informing sample data, as well as statistically by comparing the
averages of the informing composites to the block estimates, for each shear
zone.
The figures below show the results of the estimation. Black dots represent the
position of borehole intersections or underground channel samples used in the
estimate.

Mining and Metallurgical Assumptions
The deposit will be mined by underground methods.
Resources are reported at a marginal cutoff grade of 0.5 g/t, which is
calculated using a gold price of $3000/oz and a processing cost of $25 per
tonne.
Historical Mining
Bill's Luck was originally mined between 1916 and 1950. Mining was from
three shafts namely West Shaft, Main shaft and Roscor shaft. Kavango Resources
has been rehabilitating the West Shaft and Main Shaft, and accessing 2 and 3
levels underground.
Artisanal workings are continuous along the outcrop area.
The following areas were removed from the resource block model to account for
prior mining.
· All surveyed workings on surface and underground.
· All remnant areas above 2 level (996 m elevation) at Main Shaft and
Roscor Shaft.
· All remnant areas above 1 Level (2020 m elevation) at West Shaft
· All areas within 10m of the LIDAR surveyed stoped areas.
Bulk Density Determination
Dry bulk density was determined using the Archimedes Method on a large number
of samples throughout the deposit. The average dry bulk density is 2.80 tonnes
per metres cubed.
Resource Classification
The resource was classified into confidence classifications based on the
following criteria:
· Measured Resource: Areas within the densely sampled mine workings,
and adjacent areas with a borehole intersection spacing of 15 m or less were
classified as measured resource.
· Indicated Resource: Blocks within 25 m from a borehole intersection,
being within the resource drilling and grid were classified as indicated
resource.
· Inferred Resource: Blocks between 25 and 50 m from a datapoint, as
well as areas extrapolated along strike or down dip were classified as
inferred resource. Hanging wall and foot wall zones with too few
intersections to verify continuity were also classified as inferred resource.

Notes :
1. Resources are reported in accordance with the JORC Code (2012).
2. Resources are reported at a cutoff grade of 0.5g/t, based on
reasonable prospects for eventual economic extraction at a gold price of
$3000/oz.
3. Rounding as required by reporting guidelines may result in apparent
summation differences between tonnes, grade and contained metal content.
4. 'Contained Oz' refers to gold in situ, actual gold recovered will
likely be less than this amount
Conclusion and recommendations
The exploration drilling, logging and sampling have been done to a high
standard, sufficient to support a resource estimate.
The gold mineralisation at the Bill's Luck underground workings has been
demonstrated to be continuous to depth, with the potential to increase the
resources through further exploration.
Kavango's Mining Strategy at Hillside
Kavango is executing a strategy of increasing gold production in Zimbabwe by
building modern CIP plants, which have much higher throughput rates and
significantly higher gold recoveries than traditional stamp and roller milling
using static VAT leaching methodologies which are widely used in Zimbabwe, and
currently at Hillside.
Kavango will commission its first modern CIP plant, throughput capacity 50
tpd, at Hillside in Q1 2026. The Company intends to feed the 50 tpd plant with
a combination of ore mined by Kavango from the Bill's Luck underground
operation, and the Hillside contractor-mined sands.
Following publication of the preliminary JORC MRE at Bill's Luck, plus the
Nightshift resource, Kavango is evaluating an increase in processing capacity
at Bill's Luck.

to dip towards the drillhole at a steep angle (actual geometry to be confirmed
by a second hole on section in the future).
· The relatively short sample length (typically 1 m) allows for
relatively accurate localization of mineralisation.

Sample security · The measures taken to ensure sample security. · Diamond core and trench samples are stored at a secure facility at
the field office.
· Sample bags are logged, tagged, double bagged and sealed in plastic
bags stored at the field office.
· Samples are stored in a locked company compound at site and in a
locked container in Bulawayo. They are shipped onwards to the analytical
facility by a reliable commercial courier.
· Sample security includes a chain-of-custody procedure that consists
of filling out sample submittal forms that are sent to the laboratory with
sample shipments to make certain that all samples are received by the
laboratory.
· Prepared samples are transported to the analytical laboratory in
sealed bags that are accompanied by appropriate paperwork. including the
original sample preparation request numbers and chain-of-custody forms.
Audits or reviews · The results of any audits or reviews of sampling techniques and data. · The CP has visited both site and considered practices and SOPs at
