Golden Deeps Limited (“Golden Deeps” or “Company”) is very pleased to announce a series of exceptional Copper (Cu), Lead (Pb) and Vanadium (V2O5) intersections from the first 8 of 15 reverse circulation (RC) drillholes at the Nosib Block (“Nosib”) prospect in Namibia. The Nosib Block mine was a high-grade Coppervanadium mine located at the western end of EPL3543, 20km southwest, along strike, from the Companys’ Abenab high-grade Vanadium project, in the Otavi Mountain Land in Namibia (Figure 3).
All 8 of the drillholes from which results have been received produced significant copper intersections, with several holes intersecting exceptional lead grades and shallow high-grade vanadium mineralisation. The results from NSBRC007 included an exceptionally valuable intersection of 10m @ 2.65% Cu, 10.7% Pb and 3.12% V2O5 from only 3m down hole (see cross section, Figure 1 below).
Golden Deeps CEO, Jon Dugdale, commented, “The shallow depth, significant thicknesses and exceptional grades of Copper, Lead, and in several holes, Vanadium, are extremely encouraging.
“With the price of these key battery metals, Copper, Vanadium, and Lead, rapidly appreciating, we are looking forward to continuing to drill this potentially very high-value, poly-metallic, deposit.”

The mineralised intersections are hosted by a steep to moderate dipping arenaceous unit between the hangingwall dolomite and a footwall that includes a granitic dyke (see Figure 1). Historically the Nosib Block mine was developed on three levels (from 1917 to 1920) to a depth of 120m. However underground inspection indicates that no mining occurred between the levels.
The current drilling has tested between the levels to a depth of 60m to 80m below surface and for a strike length of less than 80m (see drilling plan Figure 2). Results received to date support the intersections produced from previous underground sampling by GED geologists that included:
NOUG0001 6m at 9.3% Cu, 4.72% Pb, 7.92g/t Ag[4] NOUG0005 6m at 1.51% Cu, 10.59% Pb, 7.15g/t Ag, 1.12% V2O5[4 ]
Thick intervals of copper mineralisation have also been intersected above and below the previous development including 44m @ 0.74% Cu from 46m in NSBRC003 and 43m @ 0.64% Cu in NSBRC002 and these zones remain open at depth and along strike.
Nosib was the second key target area drill tested during the initial program that also tested shallow projections of the Khusib Springs[5] deposit (see location Figure 3). A total of 25 reverse circulation (RC) holes for 1,275m were completed, including 10 holes for 331m at Khusib Springs and 15 holes for 958m at Nosib[6] . Samples from the Nosib drilling were prioritised for analyses at the Intertek laboratory in Perth after sample preparation in Namibia. Results have been received from only the first 8 holes of the Nosib program, with samples from a further 7 holes currently being processed.
Results to come include NSBRC010 that intersected a 5m interval of semi-massive copper-sulphides from only 10m downhole (8.6m below surface) within a broader zone of copper mineralisation including malachite and azurite. Significant copper mineralisation was also intersected by NSBRC009 that included a 15m zone of disseminated copper sulphide mineralisation from 55m downhole and NSBRC014 that included a 21m zone of copper mineralisation (malachite) from 23m downhole (see Appendix 1, Table ii).
Results from the drilling at Khusib Springs will be compiled when all results are received.

About the Nosib Block Copper-Silver-Lead-Vanadium Project
The Nosib Block mine was a high-grade copper-vanadium mine located at the western end of EPL3543 16km west of Khusib Springs and 20km along strike from the Company’s Abenab high-grade Vanadium Project (Figure 3). Copper mineralisation was discovered at Nosib in 1915 with mine access development work between 1917 to 1920. The historic No 2 shaft was developed on three levels to a depth of 120m but not mined. Golden Deeps’ geologists accessed the three levels of the mine and took underground channel samples from the walls of the drives. Best channel results include:
NOUG0001 6m at 9.3% Cu, 4.72% Pb, 7.92g/t Ag[4] NOUG0005 6m at 1.51% Cu, 10.59% Pb, 7.15g/t Ag, 1.12% V2O5[4 ]
The high-grade copper-silver-vanadium-lead mineralisation dips moderately to the north and is hosted by conglomerate and sandstone (mine sequence) in contact with dolomite to the north and basement granite to the south. The mineralisation shows good continuity and remains in-situ because the areas between the development drives were not mined.
The drilling at Nosib tested between the previously developed levels, targeting extensions to the high-grade copperlead-silver-vanadium ore that was channel sampled.
About the Khusib Springs Copper-Silver Project
The Khusib Springs copper-silver mine is located on EPL3543 near the town of Grootfontein in Namibia (Figure 3). Khusib Springs was a very high-grade copper-silver mine which produced approximately 300,000t of ore grading 10% Cu, 1.8% Pb and 584g/t Ag[1] . Previous drill intersections at Khusib Springs include:
KH006 4.5m at 35.19% Cu, 3.67% Pb, 2.23% Zn, 2090.91g/t Ag from 30m[2] KH008 14.0m at 8.12% Cu, 0.75% Pb, 0.52% Zn, 385.06g/t Ag from 37m[2]
Khusib Springs was mined between 1996 and 2003 after which it closed due to the very low copper price at the time and depletion of easily minable high-grade ore. At the beginning of 2003, towards the end of mining, the copper price had fallen to US$1,500 per tonne (now nearly US$10,000 per tonne).

The Khusib Springs mine is considered analogous with the Tsumeb Mine 40km to the northwest that between 1905 and 1996 produced 30Mt of ore grading 4.3% Cu, 10% Pb and 3.5% Zn[3] :
In late 2020, Golden Deeps engaged South Africa based geological consultancy Shango Solutions to complete a study on Khusib Springs to validate the historic drilling data and digitally capture hardcopy mine plans including underground development and stoping plans with a view to assess the potential for further minable ore remaining in the mine. The study was completed by Shango in January 2021.
The study demonstrates that there are remanent zones of copper-silver mineralisation on the margins of the mined stopes as well as at depth (Figure 4). The remnant ore on the margins of the stopes was probably left because of the grade in the light of the then prevailing low copper prices. Copper mineralisation has been mapped in a small working at the surface above the deposit.
The current drilling program at Khusib Springs targeted the upper part of the deposit adjacent to the old stopes and up-plunge from previously mined high-grade areas.
Deeper targets, including the discovered but not mined Khusib Deeps (see Figure 4 below) will be drill tested in subsequent drilling programs, with the objective of finding a new high-grade copper-silver deposit of similar grade to that historically mined at Khusib Springs. Targeting will be refined through review and possible re-interpretation and modelling of previous drilling and geophysics.

(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg 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. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • 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. |
• Exploration drill holes KH06 and KH08 were drilled by a diamond core drill rig. The diameter of the diamond core is not stated. Sample intervals were based on geological boundaries and zones of mineralisation identified during logging. No information is provided on how the samples were taken. • Exploration drillholes at Khusib Springs and Nosib the reverse circulation drilling was used to obtain 1 m samples from which approximately 3 kg were pulverised from which a small charge will be obtained for multi-element analysis using the ICP-MS method. |

JORC 2012 Edition - 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. |
• Drilling results are from the Khusib Springs copper prospect located on Golden Deeps Limited (Huab Energy Ltd) EPL3543 located near the town of Grootfontein in northeast Namibia. • EPL3543 expires 6thJuly 2022. • There are no material issues or environmental constraints known to Golden Deeps which may be deemed an impediment to the continuityof EPL3543. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. | • The Khusib Springs copper prospect was primarily drilled by Goldfields Namibia from 1993 onwards following the intersection of massive tennantite in drill holes KH06 and KH08. |
| Geology | • Deposit type, geological setting and style of mineralisation. | • The Khusib Springs deposit is a small but high-grade pipe- like body that plunges steeply within brecciated carbonate rocks. The deposit resembles the Tsumeb deposit near the town of Tsumeb to the northeast. • Khusib Springs is on the northern limb of the Harasib- Olifantsfontein syncline and is hosted by carbonates of the Maieberg Formation (Lower Tsumeb Subgroup). • The Nosib Mine was worked historically to produce copper and vanadium. The deposit is arenite / sandstone-hosted with chalcopyrite, bornite, galena and pyrite as well as secondary descloizite (Lead-Vanadium hydroxide). The mineralization is associated with prominent argillic alteration and occurs within an upper pyritic zone of the Nabis Formation sandstone, which is locally gritty to conglomeratic. The main zone of mineralization at Nosib cross-cuts the stratigraphyand also includes stratiform |

| mineralization with significant chalcopyrite, striking northeast-southwest and dipping moderately to the northwest. |
||
|---|---|---|
| Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collaro elevation or RL (Reduced Level – elevation above sea level inmetres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho 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. |
• Refer to Appendix 1 of the ASX announcement. |
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g., 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. |
• All exploration results are reported by a length weighted average. This ensures that short lengths of high-grade material receive less weighting than longer lengths of low- grade material. |
| 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, there should be a clear statement to this effect (e.g., ‘down hole length, _true width not known’). _ |
• Drill holes and drill traverses were designed to intersect the targeted mineralised zones at a high angle where possible. |

| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Refer to Figure 1 for a representative cross section of the Nosib deposit and Figure 2 is a plan-view representation of the drillhole collars and drillhole traces. |
|---|---|---|
| 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. |
• Drillholes KH06 and KH08 are representative of the high grade tennantite rich massive sulphide zones in the deposit. • Intersections in all drillholes above designated cut-off grades are reported in Table 1 of the release. |
| 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. |
• No other data is material to this report. |
| Further work | • The nature and scale of planned further work (e.g., tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• RC drilling commenced in May 2021 testing areas marginal to the historic stopes in the upper part of the Khusib Springs deposit. • Upon receipt of all results from the initial program at Nosib, interpretation and modelling of the intersected mineralisation will be carried out prior to planning of further drilling. |
