LARGE STEP-OUT HOLE SHOWS STRIKE CONTINUITY OF HIGH-GRADE COPPER
Cosmos Target, Ngami Copper Project, Botswana
______________
Cobre Limited (ASX: CBE , Cobre or Company ) is pleased to announce early results from the Cosmos Target drill programme ( see ASX announcement 23 October 2025 ) on its wholly owned Ngami Copper Project ( NCP ), Botswana.
HIGHLIGHTS:
-
Visual mineralisation estimates, substantiated by pXRF analysis, have defined a promising intersection of vein, cleavage and fracture hosted chalcocite mineralisation in drill hole NCP68 located 400m along strike from NCP55 which includes 10.0m @ 1.32% Cu & 27.7g/t Ag ( see ASX announcement 3 February 2025[1] );
-
Results provide encouragement for a laterally extensive (>400m) higher-grade copper silver zone at Cosmos; and
-
Based on these encouraging preliminary results, two further infill diamond drill holes, located on either side of NCP55, have been added to the drill programme.
The expanded drill programme will corroborate the continuity of higher-grade copper and silver mineralisation at the Cosmos Target. The higher grades at Cosmos may provide opportunity for both In-Situ Copper Recovery ( ISCR ) and conventional underground mining.
Commenting on the early results from the Cosmos Target Drill Programme, Adam Wooldridge, Cobre’s Chief Executive Officer, said:
“This is a great start to the Cosmos drill programme with early results confirming the higher background copper grades at this extensive target. The next two drill holes will provide important indicators of grade continuity and variability which will guide our follow-up programme.”

The Cosmos Target is located approximately 8 km along strike from the Comet Deposit ( 11.5Mt @ 0.52% Cu and 11.6 g/t A g indicated and inferred resource[2] ) and includes approximately 5km of strike length of anomalous copper silver mineralisation defined by 2km wide spaced diamond drilling. Cosmos is part of the greater NCP Exploration Target (estimated at 205 to 308 million tonnes at 0.31 to 0.46 % Cu & 5.5 to 8.3 g/t Ag – refer footnote 2 ), with evidence for higher grade zones which may be economic from an underground mining perspective highlighted by drill hole NCP55 ( see ASX announcement 4 August 2025 ).
Cautionary Statement: The potential quality and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and there is no certainty that further exploration work will result in the determination of a Mineral Resource.
The ongoing drill programme at Cosmos was originally designed to assess the strike continuity of higher-grade mineralisation intersected in NCP55 on 400m step-outs and consisted of two diamond drill holes totalling 496m. Based on visual estimates supported by pXRF measurements, NCP67, located to the northeast of NCP55 returned relatively average copper grades. However, the intersection in NCP68, located 400m to the southwest of NCP55, appears more significant, comprising notable vein, fracture and cleavage hosted chalcocite mineralisation logged over 6m from 198 to 204m downhole (approximately 4m true width). Based on these results, the drill programme has been extended to include two additional infill holes. Assay results are expected towards the end of January 2026.

Visual Mineralisation Logging and Disclaimers
Detailed logging of mineralisation including type, setting and abundance has been combined with spot portable XRF measurements taken at 10cm intervals to verify the results. Drill core is currently being cut and sampled and will be sent for assays in the coming week. Assay results are anticipated towards the end of January 2026. A visual mineralisation log is provided in Table 2 below.

Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations.
pXRF analyses are only indicative of mineralisation grade and should not be considered equivalent of laboratory analyses. Laboratory assays are expected in late January 2026.
Geology and Mineralisation
Mineralisation at NCP is sedimentary-hosted, structurally controlled, copper-silver associated with the redox contact between oxidised Ngwako Pan Formation red beds and overlying reduced marine sedimentary roc s of the D’Kar ormation on the imbs of anticlinal structures. Drilling has focussed on the southern anticlinal structure which extends for over 40km across the NCP with evidence for anomalous Cu-Ag mineralisation on both northern and southern limbs. Drilling results to date have returned consistent, wide intersections of anomalous to moderate-grade Cu-Ag values over extensive strike lengths with smaller structurally controlled higher-grade zones. This style of mineralisation is dominated by fine-grained chalcocite which occurs along cleavage planes (S1) and in fractures rather than the vein hosted bornite with chalcopyrite more typical of the KCB style. Importantly, the chalcocite mineralisation is amenable to acid leaching, occurs below the water table and is associated with well-developed fracture zones bounded by more competent hanging and footwall units satisfying key considerations for ISCR.
Target Model
The NCP area is located near the northern margin of the KCB and includes significant strike of subcropping Ngwako Pan / D’Kar ormation contact on which the majority of the nown deposits in the KCB occur.

Basis of the Exploration Target:
-
Mineralisation at NCP is sedimentary-hosted, structurally controlled, copper-silver associated with the redox contact between oxidised NPF red beds and overlying reduced marine sedimentary rocks of the DKF on the limbs of anticlinal structures with smaller structurally controlled higher-grade zones. This style of mineralisation is dominated by fine-grained chalcocite which occurs along cleavage planes (S1) and in fractures. Importantly, the chalcocite mineralisation is associated with well-developed fracture zones bounded by more competent hanging and footwall units.
-
A database of 17 diamond core drill holes (totalling 4,146m) over the NCP, geophysical mapping, downhole orientated core structural data, lithological and regional structural interpretation.
-
Drillholes used to inform the Comet MRE were excluded.
-
Exploration Target modelling was completed in Leapfrog Geo to produce a mineralised solid to determine volume, above 545m RL.
-
A dry bulk density of 2.81 t/m3 was used to determine tonnage from the modelled volume, based on the available density data for the NCP.
-
Copper grades of raw samples were capped to 2%, silver grades were capped to 30 g/t, based on log probability plots and observed break points in the data distributions, before length weighted averages were reported.
-
Unclassified tonnage below and adjacent to the Comet MRE were included in the Exploration Target.
-
The Exploration Target range was calculated by applying ±20% to the tonnes and grade.
-
The focus area for the model is the southern anticline structure extends for approximately 25km along strike with anomalous copper intersections on both fold limbs.

| 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 ch ical d ail from h ompa y’ xplora io a d drilling program at the Ngami Copper Project (NCP) located within the Ngamiland District on the Kalahari Copper Belt, Republic of Botswana. • Representative diamond half core samples are taken from zones of interest. Samples were taken consistently from the same side of the core cutting line. Core cutting line is positioned to result in two splits as mirror images with regards to the mineralisation, and to preserve the orientation line. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used |
• Diamond core sample representativity was ensured by bisecting structures of interest, and by the sample preparation technique in the laboratory. • The diamond drill core samples were selected based on geological logging and pXRF results, with the ideal sampling interval being 1m, whilst ensuring that the sampled interval does not cross any logged significant feature of interest. • Individual core samples were crushed entirely to 90% less than 2mm, riffle split off 1kg, pulverise split to better than 85% passing 75 microns (ALS PREP-31D). • Sample representivity and calibration for ICP AES analysis is ensured by the insertion of suitable QAQC samples. • Samples are digested using 4-acid near total digest and analysed for 34 elements by ICP-AES (ALS ME- ICP61, and_ME-ICP61a). • _Over range for Cu and Ag are digested and analysed with the same method but higher detection limits (ALS ME-OG62). |

• Data spacing and distribution of all survey types is deemed appropriate for the type of survey and equipment used. • Drill hole spacing for the Comet MRE is approximately 130 m along strike and 45 m across strike. • Drill hole spacing for the Exploration Target varies between 500m to greater than 5000m, as might be expected for this stage of exploration. |
| Whether sample compositing has been applied. |
• N/A | |

| 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. |
• Drilling was typically completed perpendicular to the strike of the mineralisation, approximately 150o azimuth, at a dip of -60o. For the current phase of drilling, holes are oriented approximately 330 azimuth and an inclination of -60 to obtain better intersection angles of the overturned units. • Drillhole intersection angles with the mineralisation contact were sub-optimal (approximately 25o from the core axis) and may have affected sample selection at mineralisation boundaries. This phase drillholes drilled towards the north west have better intersection angles with the mineralisation (approximately 40) |
| 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. |
• Current available data indicates mineralisation occurs within steep, sub-vertical structures, sub- parallel to foliation. |
|
| Sample security |
The measures taken to ensure sample security. |
• Sample bags are logged, tagged, double bagged and sealed in plastic bags, stored at the field office. • Diamond core is stored in a secure facility at the field office and then moved to a secure warehouse. • 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 were transported to the analytical laboratory in sealed gravel 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. |

JORC Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• Cobre Ltd holds 100% of Kalahari Metals Ltd. • Kalahari Metals in turn owns 100% of Triprop Holdings Ltd and Kitlanya (Pty) Ltd both of which are locally registered companies. • Triprop Holdings holds the NCP licenses PL035/2017 (306.76km2) and PL036/2017 (49.8km2), which, following a recent renewal, are due for their next extension on 30/09/2026 • Triprop Holdings holds the additional infill licenses PL252/2022 to 255/2022 which are due for their next renewal on 31/12/2027. |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
• Previous exploration on portions of the NCP was conducted by BHP. • BHP collected approximately 113 soil samples over the NCP project in 1998. • BHP collected Geotem airborne electromagnetic data over a small portion of PL036/2012. |
| Geology | Deposit type, geological setting and style of mineralisation. |
• The regional geological setting underlying all the Licences is interpreted as Neoproterozoic meta sediments, deformed during the Pan African Damara Orogen into a series of ENE trending structural domes cut by local structures. • The style of mineralisation comprises strata- bound and structurally controlled disseminated, cleavage and vein hosted Cu- Ag mineralisation. |

Drill hole A summary of all information Information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
easting and northing of the drill hole collar
elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar
• Summary table of all completed core drill holes on the NCP licenses is presented below. All coordinates are presented in UTM Zone 34S, WGS84 datum. All the holes have been re-surveyed with differentially corrected GPS. Drill holes designated TRDH are original holes drilled by Triprop in 2014, MW are monitoring wells and PW injection/pumping wells.
Summary results of intersections are provided using a cut-off of 0.2% Cu ranked according to intersection width and grade. Summary results for of > 1% Cu over 1m are provided in the following table.
dip and azimuth of the hole
down hole length and interception depth hole length.
If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.

| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• Grades were capped at 2% Cu and 30 g/t Ag for the reporting of the Exploration Target. • Length-weighted average was used in the reporting of the Exploration Target grade. • No aggregation of intercepts has been reported. • Copper equivalents were not reported for the Mineral Resource estimate or Exploration Target. |

| 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. If it is not known and only the down hole lengths are reported, |
• Down hole intersection widths are used throughout. • Diamond holes are drilled at -60o towards 150o azimuth, with mineralisation typically oriented sub-vertical resulting in a relatively low intersection angle. • The hydrogeological percussion drilling was drilled down mineralisation in order to intersect the fracture zones associated with the mineralisation – this results in long- intersections which are noted in the |

| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• Results from the previous exploration programmes are summarised in the target priorities which are based on an interpretation of these results. • The accompanying document is considered to be a balanced and representative report. |

| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• The project area has been surveyed using high resolution magnetic data, airborne electromagnetics and airborne gravity gradient surveys. These results provide a guide to identifying the mineralised contact including evidence for further untested mineralised contact • 11,400 soil samples, collected across the property have been analysed using a combination of pXRF, ICPMS and partial leach analysis. This data has been used successfully to target portions of the contact _deemed to be better mineralised. _ |
