Golden Deeps Limited (“Golden Deeps” or “Company”) is pleased to announce that drilling at the Nosib prospect in Namibia has intersected thick intervals of copper mineralisation in 13 of the 15 RC holes completed, including semi-massive copper-sulphides over 5m in NBRC010.
The Nosib Block mine was a high-grade copper-vanadium mine located at the western end of EPL3543 16km west of Khusib Springs in the Otavi Mountain Land in Namibia (Figure 1).
Historically Nosib was developed on three levels (from 1917 to 1920) to a depth of 120m but not mined. The current drilling has tested between the levels to a depth of approximately 60m to 80m below surface and for a strike length of less than 80m. Thick intervals of copper mineralisation, including copper carbonates - malachite and azurite, as well as sulphides, predominantly tennantite, have been intersected in 13 of the 15 RC holes completed and include up to 33m of downhole mineralisation, averaging 13m aggregate thickness. One hole, NSBRC 010, intersected a 5m interval of semi-massive copper sulphides from only 10m downhole (8.6m below surface).

A total of 25 reverse circulation (RC) holes for 1,275m have been completed in the current program, including 10 holes for 331m at Khusib Springs and 15 holes for 958m at Nosib.
Nosib is the second key target area drill tested following the completion of the initial program at Khusib Springs (see previous ASX release, 10 May 2021).
The development levels at the Nosib mine were previously accessed by GED geologists and the highgrade copper-silver-vanadium-lead mineralisation exposed in the drives was sampled, generating channel sample results that 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 ]
At the Khusib Springs mine, that previously produced 300,000t at 10% Cu and 584g/t Ag[3] , the RC drilling program is targeting high-grade copper-silver mineralisation adjacent to the historic stopes and up plunge from ore-bodies mined underground but not stoped to surface.
Significant copper mineralisation (malachite, azurite and tennantite) was intersected in two of the holes drilled, KHRC004 and KHRC007, into the up-dip extensions of the deposit near shallow surface workings. Previous intersections in these mined areas included:
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]
Al drilling samples are in the Perth laboratory having previously been sample-prepped in Namibia. Analytical results are expected within weeks.
Details of drillholes completed and mineralised intersections are summarised in Appendix 1, ii).

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 1). 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 $1,500 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 2). 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 is targeting 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 2 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 reinterpretation and modelling of previous drilling and geophysics.

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 (Figure 2). 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.
Underground sampling was conducted by Golden Deeps along the development drives on three levels. Best channel results include:
==> picture [300 x 27] intentionally omitted <==
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 current drilling at Nosib is testing between the previously developed levels, targeting extensions to the high-grade copper-lead-silver-vanadium ore that was channel sampled.

| 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 (eg ‘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 (eg 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 will be pulverised from which a small charge will be obtained for multi-element analysis. |
| Drilling techniques |
• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). |
• Exploration drill holes KH06 and KH08 were drilled by a diamond core drill rig. No information is provided on the size of the diamond core or how the samples were taken. • Exploration drillholes at Khusib Springs and Nosib were Reverse Circulation percussion drilling method (RC drilling). |
| Drill sample recovery |

| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
• No information is provided on the data management and verification procedures. • All drill data relating to the Khusib Springs project (including holes KH06 and KH08) generated by Goldfields Namibia or other companies was reviewed and validated in detail by Shango Solutions, a geological consultancy based in South Africa. No significant errors were found in the data. • Information regardingverification ofsampling and assaying methods for the exploration drillholes at Khusib Springs and Nosib will be provided upon receipt of results. |
| 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. • Specification of the grid system used. • Quality and adequacy of topographic control. |
• The majority of the drill data was captured using the UTM33S grid. • Location of the exploration drillholes at Khusib Springs and Nosib provided in Appendix 1, ii). |
| 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. • Whether sample compositing has been applied. |
• Exploration drill holes were drilled at close spacing, commonly 15m to 20m or less because of the small diameter and plunging orientation of the orebody. |
| 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. • 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. |
• Holes were drilled vertically or were angled to best intersect the plunging orebody. • The majority of the angled holes were drilled on azimuth 323 degrees at a dip of -50 degrees (UTM33S grid). |

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 MaiebergFormation(Lower Tsumeb Subgroup). |
| 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 isjustified 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. |
• 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 (eg ‘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 3 of the ASX announcement. |
| 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. |
| 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 (eg 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 2020 testing areas marginal to the historic stopes in the upper part of the deposit. |
