Technical Update - Hillside Structural Report
Kavango Resources plc (LSE:KAV), the Southern Africa focused metals exploration and gold production company, is pleased to present a Technical Update on the ongoing structural work on the Hillside Project ("Hillside"), Zimbabwe. The analysis and insights are provided by the Technical team in conjunction with Murgana Structural Consulting, Sofia, Bulgaria.
Overview
At the Nightshift, Bill's Luck, and Steenbok Prospects at Hillside, within Zimbabwe's Filabusi Greenstone Belt, gold-bearing quartz veins have been confirmed to occur within well-developed shear zones. Preliminary structural interpretations highlight the importance of understanding the broader kinematic framework of these shear zones, as it provides critical insights into the controls on mineralisation. This knowledge is expected to inform the anticipated geometry of mineralised domains, guide more effective exploration strategies, and assist with vein recognition in drill core. Furthermore, if stretching lineation influenced fluid flow during mineralisation, the associated shear zone kinematics may offer valuable predictive guidance on the plunge orientation of potential orebodies.
Ben Turney, Chief Executive Officer of Kavango Resources, commented:
"As Kavango continues to make progress helping to unlock Zimbabwe's goldfields, we will start to release some more technical announcements, alongside our standard market releases. We will title these as "Technical Updates" and the primary audience will be exploration and mining experts.
In this first Technical Update, we have successfully completed a study that has constrained the structural controls on gold mineralisation in three key shear zones of the Filabusi Greenstone Belt. Understanding the structural controls for gold mineralisation is crucial for discovering gold mines.
At Hillside, the oblique-dominated shear zones and reactivated fabrics represent significant targeting criteria for ongoing gold exploration. We are encouraged by what we have proven and believe this will us accelerate development of our Steenbok, Nightshift and Bill's Luck mining targets."
Highlights
· Analysis of the results from regional traverse mapping, exploration-scale structural mapping and detailed core-logging showed that mineralisation across the Bill's Luck, Nightshift and Steenbok Prospects associates with shear zones that have acted as fluid conduits and controlled the alteration, vein density and gold mineralisation.
· Excellent correlation between high-strain domains, intervals with higher intensities of the alteration and gold mineralisation has been confirmed in all targets.
· Meso-scale structural analysis showed the synkinematic character of the mineralised vein-system.
· Oriented rock samples were collected across the Night Shift, Bill's Luck, and Steenbok shear zones to analyse shear-related fabric development and their relationship to gold mineralisation. Microstructural analysis combined with petrography and ore mineralogy studies is planned to provide additional details on the relationships between deformation, fluid circulation, alteration and mineralisation.
· The shear zones host auriferous quartz veins and exhibit transpressional, oblique strike-slip kinematics with a dominant dextral sense of shear at Night Shift and Bill's Luck targets and sinistral lateral component at Steenbock, thus enhancing predictability of mineralised vein orientation.
· The oblique shearing is associated with moderately to steeply NE-plunging mineral and mineral stretching lineation at Night Shift and Bill's Luck targets, whereas at Steenbock it is moderately to gently SW-plunging.
· Meso-scale indicators showed that the visible mineralisation is synkinematic to the shearing, occupies structurally controlled sites and shows indications for accumulations parallel to the mineral stretching lineation, the later interpretation still considered as preliminary.
· Late-stage reactivation and evidence of sub-horizontal lineation suggest multiple deformation episodes affecting the Steenbok shear zone.
· Alteration zones with pervasive sericitisation, carbonate, and sulphide staining were documented, spatially associated with milky quartz veins.
Domains of higher strain with sheared, smokey-gray, syntectonic quartz-veins are associated with the intervals that have the best assay results so far.Ongoing structural work in Zimbabwe
Recent structural and kinematic analysis across the Bill's Luck, Night Shift, and Steenbok prospects at Hillside, within Zimbabwe's Filabusi Greenstone Belt has provided significant insight into the controls on gold mineralisation.
The Bill's Luck and Night Shift shear zones are interpreted as segments of the regionally extensive WNW-trending Redwing shear zone, which, along with the regional NE-trending Irisvale-Lancaster shear zone (hosting the Steenbok prospect), truncates the Filabusi and Fort Rixon greenstone belts. These shear zones are believed to have developed around 2.59 Ga during NNW-SSE contraction associated with deformation along the Northern Marginal Zone of the Limpopo Belt.
Structural analysis reveals that the Redwing Shear Zone has a pronounced dextral strike-slip kinematics. The shear zones at Bill's Luck and Night Shift exhibit oblique-slip character with partitioned strain distributed across a network of discrete, anastomosing shear zones. Structural fabrics, including steep NNE-dipping mylonitic foliations and NE-plunging stretching lineations, support a dextral-oblique (normal) shear sense in the southern exposures near the Insiza River. This geometry is consistent with a dextral oblique-slip system that evolves along strike from dominantly strike-slip in the southeast to more oblique-slip character north-westward toward the Bill's Luck and Night Shift prospects, although this remains to be proven.
In contrast, the Irisvale-Lancaster shear zone at Steenbok preserves a more complex deformation history, marked by three distinct phases: These episodes reflect a protracted and multiphase deformation history, which requires further mapping and analysis. The current interpretation of the gold-mineralisation event correlates with an early stage of regional-scale sinistral transpression.
Importantly, the gold-bearing quartz veins hosted in both the Redwing and Irisvale-Lancaster shear zones appear to have formed synchronously with early stages of shearing. Field observations suggest that stretching lineation played a key role in fluid flow pathways during mineralisation. Consequently, orebodies are expected to plunge parallel to lineation-steeply to moderately NE or ENE at Bill's Luck and Night Shift, and moderately SW at Steenbok. These findings confirm the structural control on gold mineralisation in the Filabusi Greenstone Belt and provide predictive vectors for targeting mineralised shoots.
Kavango's Operations in Zimbabwe
Kavango is exploring for gold deposits in Zimbabwe that have the potential to be developed into commercial scale production quickly through modern mechanised mining and processing. The Company is targeting both open-pit and underground opportunities.
Kavango has two projects on the Filabusi greenstone belt, Hillside and Nara.
Kavango owns 100% of the Hillside Gold Project, having exercised its option in April 2024. Here, the Company has three high priority targets it aims to bring into production over the next 18 months: Bill's Luck, Steenbok and Nightshift. At Nightshift, Kavango is investigating the potential for a selective open-pit mining operation, followed by underground mechanised mining. Meanwhile, at Steenbok, Kavango is pursuing a high-grade mechanised underground mining opportunity. Kavango is currently analysing the latest drill data from Bill's Luck and will provide an update shortly.
In addition, Kavango will soon acquire 100% of the Nara Gold Project, having exercised its option in June 2025. Here, the Company is exploring for a large-scale, mechanisable underground gold deposit. The primary target zone is around the historic N1 mine, where the Company is assessing the potential to expand artisanal workings both at depth and along strike.

Sampling techniques |
Nature and quality of sampling (e.g. cut channels. random chips. or specific specialised industry standard measurement tools appropriate to the minerals under investigation. such as down hole gamma sondes. or handheld XRF instruments. etc). These examples should not be taken as limiting the broad meaning of sampling. |
· The information in this release relates to the technical details from the Company's exploration and drilling program at Hillside Project which lies within the Filabusi Greenstone Belt, Matabeleland, Zimbabwe. · Surface Diamond drilling (HQ & NQ) was carried out and half core samples were taken from the entire hole. · Core was cut into two using a commercial core saw adjacent to the Ori line to produce two splits as mirror images with regards to igneous textures, sedimentary bedding where possible structural fabric. · Underground Diamond drilling (AXT - 30.5mm) was carried out and full core samples were taken from the entire hole. · No orientation was possible on the underground drill core. · Samples were taken based on geological contacts, and/or of up to approximately 1m in length. The minimum sample width is 30cm to cater for distinct quartz veins which may be diluted and obscured if 1m widths were to be maintained. · Reverse Circulation drilling was also carried out, with representative samples split on site after individual 1m samples were collected from the cyclone. · Two samples were taken using a riffle splitter from the original 1m sample. · Core samples were submitted for a 25g fire assay with AAS finish. to Performance Laboratories (Pvt) Ltd., at Harare, Zimbabwe. · Selected samples will be sent to a check lab, ALS laboratories, Johannesburg, for referee fire assay comparison. · Kavango routinely takes pXRF readings along the core using an Olympus Vanta on Geochem 3 beam mode 60 seconds. |
|
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used |
· All Kavango's drill samples were geologically logged by suitably qualified geologists on site. · Sample representativity was ensured where possible by drilling perpendicular to structures of interest, and by the sample preparation technique in the laboratory. · The entire borehole was sampled based on geological logging, with the ideal sampling interval being representative of lithology for diamond core. · Individual samples are weighed at the field camp. · Upon arrival at Performance lab, the samples are dried at +/- 105 deg Celsius for 8 to 12 hours. · Entire sample is crushed to 100% passing 4.75mm. The crushers have inline rotary splitters that split off 500g of sample that is pulverized. · The 500g split is pulverized in a Rocklabs pot and puck pulveriser with 85% passing minus 75μm. · A standard 25g aliquot is used for Fire Assay. · Following industry best practice. a series of certified reference materials (CRM's), duplicates and blanks were included for QAQC as outlined further below. |

|
Aspects of the determination of mineralisation that are Material to the Public Report. |
||
|
In cases where 'industry standard' work has been done this would be relatively simple (e.g. 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases. more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
||
|
Drilling techniques |
Drill type (e.g. core. reverse circulation. open-hole hammer. rotary air blast. auger. Bangka. sonic. etc) and details (e.g. core diameter. triple or standard tube. depth of diamond tails. face-sampling bit or other type. whether core is oriented and if so. by what method. etc). |
· The surface diamond drill holes were drilled using a diamond drill operated by Equity Drilling Limited. · Equity use HQ and NQ diameter conventional core barrel. · The underground diamond drill holes were drilled by DHB drilling, Zimbabwe
|
|
Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
· Core recovery was monitored closely throughout. · Recovery in rock was >95%. · Any voids were noted. |
|
Measures taken to maximise sample recovery and ensure representative nature of the samples. |
· Samples prepared for assay are taken consistently from the same side of the core cutting line to avoid bias. · Geologists frequently check the core cutting procedures to ensure the core cutter splits the core correctly in half. · Underground diamond drill cores were not split and the whole core was sampled and submitted for assay · Core samples for assay are selected within logged geological, structural, mineralisation and alteration constraints. · Samples are collected from distinct geological domains with sufficient width to avoid overbias. |
|
|
Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
· For Diamond drilling sample recovery was generally very good and as such it is not expected that any such bias exists. |
|
|
Logging |
Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation. mining studies and metallurgical studies. |
· Kavango's Diamond drill core is logged by a team of qualified geologists using predefined lithological, mineralogical, physical characteristic (colour, weathering etc) and logging codes. · Diamond drill core was marked up on site and Geotechnical logging was completed at the rig to ensure recoveries were adequately recorded. · Lithological, structural, alteration and mineralisation are logged at camp. · The core is securely stored at the base camp. · The geologists on site follow industry best practice and standard operating procedure for diamond core drilling. · The core is photographed wet and dry with pXRF and magnetic susceptibility data also captured. · Density measurements for drill core were determined by Archimedes density measurements i.e. using a precision balance to weigh sample in air and in submerged in water. A representative piece of core was selected from each sample for density measurement. · The QA/QC compilation of all logging results are stored and backed up on a data cloud. |
|
Whether logging is qualitative or quantitative in nature. Core (or costean. channel. etc) photography. |
· All logging is conducted in accordance with Kavango's SOP and standard published logging charts and classification for grain size, abundance, colour and lithologies to maintain a qualitative and semi-quantitative standard based on visual estimation. · Magnetic susceptibility readings are also taken every metre and/or half metre using a ZH Instruments SM-20/SM-30 reader. · All core drilled was photographed wet and dry according to industry best practice. |
|
|
The total length and percentage of the relevant intersections logged. |
· 100% of all recovered intervals are geologically logged. |
|
|
Sub-sampling techniques and sample preparation |
If core. whether cut or sawn and whether quarter. half or all cores taken. |
· Selected diamond core intervals are cut in half with a commercial core cutter. using a 2mm thick blade · One half is sampled for analysis while the other half is kept for reference. · Some of the retained half core is submitted for metallurgical test work. · For selected petrographic samples core is quartered. · Undergound diamond drill cores are not cut and the whole core is sampled and submitted for assay. |
|
For all sample types. the nature. quality and appropriateness of the sample preparation techniques |
· Field sample preparation is suitable for the core samples. · RC samples are weighed at site as they come off the cyclone and every effort is made to ensure each metre sample is representative of the length drilled, with proportional volume and weight recorded. · The laboratory sample preparation technique is considered appropriate and suitable for the core samples and as well as for the expected grades. |
|
|
Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. |
· Kavango's standard field QAQC procedures for drilling samples include the field insertion of blanks, an appropriate selection of standards, field duplicates, replicates, and selection of requested laboratory pulp and coarse crush duplicates. · These are being inserted at a rate of 2.5- 5% each to ensure an appropriate rate of QAQC. |
|
|
Measures taken to ensure that the sampling is representative of the in-situ material collected. including for instance results for field duplicate/second-half sampling. |
· Sampling is deemed appropriate for the type of survey and equipment used. · Quarter diamond core duplicates are not deemed appropriate for this type of gold mineralisation. This could potentially bias the sample due to the nugget effect and vein hosted nature of the mineralisation and would reduce the sample volume. · Laboratory duplicates are produced from the crushed and milled core. · RC samples are split to provide representative duplicate samples using a commercial riffle splitter. |
|
|
Whether sample sizes are appropriate to the grain size of the material being sampled. |
· On occasions gold from this project may be coarse, therefore, some nugget effect is expected. This is minimised by using the largest diameter of core possible with the available equipment, and by utilising halved rather than quartered core for assay. |
|
|
Quality of assay data and laboratory tests |
The nature. quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
· A company audit was made of the assay laboratory in this case Performance Laboratories before it was engaged. · The digest and fire assay technique provide a total analysis method. · Between 5% and 20% of submitted samples consisted of additional blank, duplicate (lab duplicate from splitting the pulp), and standard samples. · Round robin and accreditation results for the laboratory were reviewed and considered acceptable. · The company's QAQC samples, including standards, are considered to confirm acceptable bias and precision with no contamination issues identified. |
|
For geophysical tools. spectrometers. handheld XRF instruments. etc. the parameters used in determining the analysis including instrument make and model. reading times. calibrations factors applied and their derivation. etc.
Nature of quality control procedures adopted (e.g. standards. blanks. duplicates. external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
· Kavango use ZH Instruments SM20 and SM30 magnetic susceptibility meters for measuring magnetic susceptibilities and readings are randomly repeated to ensure reproducibility and consistency of the data. · An Olympus Vanta C-series pXRF instrument is used in 3-beam geochemical mode with reading times of 60 seconds in total. Measurements are taken on clean dry core. · For the pXRF results no user factor was applied as per Kavango's SOP. The units are calibrated daily with their respective calibration disks. · All QAQC samples were reviewed for precision and accuracy. Results were deemed repeatable and representative: · For pXRF appropriate certified reference materials are inserted on a ratio of 1:25 samples. · Repeat readings are taken every 25 samples. and blank samples are inserted every 25 samples. · QAQC samples are reviewed for consistency. · pXRF CRM values show a slight positive bias. including for Cu. · At low levels (<10ppm) silver values in particular are scattered. · When laboratory assay results are received blank, standard, and duplicate values are reviewed to monitor lab performance. · Select low, moderate and high grade assay samples will be sent for check analysis at an internationally accredited laboratory for referee comparison |
|
|
|
· Performance Lab insert their own CRM's, duplicates and blanks and follow their own SOP for quality control. · Performance Laboratories are locally accredited but not internationally accredited. · Kavango is aware of this and carries out exhaustive QAQC checks and works with Performance to ensure accuracy and repeatability. · A number of samples, including one entire hole from twinned pair have been sent to Performance in Zimbabwe and ALS Laboratories in South Africa, with acceptable results · Further external referee laboratory checks will be carried out as and when sufficient holes have been drilled to warrant. |
|
|
Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
· All drill core intersections were verified by peer review. · The Company's internal CP reviewed sampling and has visited site and the laboratory to verify protocols. · Assay data was received as assay certificates and cross checked against sample submission data to ensure a correct match. |
|
The use of twinned holes. |
· In previous drilling at Bills Luck, one hole was abandoned and the follow-up hole was designed as a twin. |
|
|
Documentation of primary data. data entry procedures. data verification. data storage (physical and electronic) protocols. |
· All data is electronically stored with peer review of data processing and modelling. · Data entry procedures standardized in SOP data checking and verification routine. · Data storage is on a cloud storage facility with access controls and automatic backups. |
|
|
Discuss any adjustment to assay data. |
· No adjustments were made to assay data. |
|
|
Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys). trenches. mine workings and other locations used in Mineral Resource estimation. |
· Kavango's surface drill collar coordinates are captured by using handheld Garmin GPS and verified by a second handheld Garmin GPS. · Drill holes are routinely re-surveyed with differential DGPS at regular intervals to ensure sub-metre accuracy as and when sufficient holes warrant. · Downhole surveys of drill holes were done using an AXIS Champ Mag tool or the Champ Gyro (for DTH). · Underground drill holes are surveyed by a qualified underground surveyor using measured in pegs. |
|
Specification of the grid system used. |
· The grid system used is UTM 35S Arc 1950. All reported coordinates are referenced to this grid. |
|
|
Quality and adequacy of topographic control. |
· Topographic control is based on satellite survey data collected at 30m resolution. Quality is considered acceptable. |
|
|
Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing. and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. |
· Data spacing and distribution of all survey types is deemed appropriate for the type of survey and equipment used. · The drilling programs are designed to target the multiple interpreted parallel auriferous veins at the Bills Luck Mine on the Prospect Claims.
|
|
Whether sample compositing has been applied. |
· No composite samples have been done |
|
|
Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known. considering the deposit type. |
· Drill spacing is currently variable but is considered appropriate for this stage of exploration. · Hole orientation is designed to intersect the target structures as perpendicular as is practical. · This is considered appropriate for the geological setting and for the known mineralisation styles. |
|
If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias. this should be assessed and reported if material. |
· Existence, and orientation of preferentially mineralised structures is not yet fully understood but current available data indicates mineralisation occurs within steep. sub-vertical structures, with the possibility of plunging "ore-shoots". · The drillholes are inclined towards the target, which is understood 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. · No significant sampling bias is therefore expected. |
|
|
Sample security |
The measures taken to ensure sample security. |
· Diamond core is stored together in 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. |

Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known. its nature should be reported.

· Down hole intersection widths are used throughout. · Most of the drill intersections are into steep to vertically dipping units. True thickness is presently unknown and will be determined based on additional drilling. · All measurements state that downhole lengths have been used as the true width cannot yet be established by the current drilling. · Due to the structural control on the mineralisation and the anastaomosing nature of the shears, together with an inferred plunge more drilling is required to provide accurate measurements for true thickness |
