==> picture [478 x 11] intentionally omitted <==
Golden Deeps Limited (“GED” or “Company”) is pleased to announce the results in from its newly completed three part Phase 1 Resource Definition and Development Drilling Program at the Company’s Abenab Vanadium Project in Namibia. The program (completed in July) comprised a total of 23 holes for 3,638m which included in-fill and extension diamond drill holes into the existing Abenab resource and shallow reverse circulation (RC) drilling around the historic open pit.
The Phase 1 Program commenced in April 2019, and was designed to underpin the Company’s near-term plans to develop a mining operation at Abenab. Phase 1 consisted of three key focal areas:
-
Resource Definition Drilling
-
Mine Development Drilling
-
Surface Mineralised Ore Drilling

GED Chairman Michael Minosora stated “The initial results from our Phase 1 Resource Definition and Development Drilling Program are very positive and highlight the real potential that exists at Abenab for a further increase in the size of the existing resource. Of significance, intersection grade results from Hole ABD015 are likely to result in an increase in resource tonnes of our existing Inferred Mineral Resource of 2.80Mt @ 0.66% V2O5 (vanadium pentoxide), 2.35% Pb (lead), 0.94% Zn (zinc) at a 0.2% V2O5 cutoff. This is a fantastic result for the Company and its shareholders given we only recently upgraded the resource earlier this year and whilst we still await some results from Phase 1, we are looking forward to commencing Phase 2 drilling in Q4.”
Resource Definition and Drilling Program
To date, the Company has received results from two of the five diamond holes; ABD015 and ABRCD016 (Figure 1).

Figure 1: Abenab Mine drill hole location plan.
Hole ABD015 is located centrally within the Abenab resource and intersected brecciated dolomite with spar calcite-descloizite (PbZn(VO4)(OH)) fracture fill from 208m to 272m (Figure 2). The best intersection at a cut-off grade of 0.2% V2O5 is:
- 64.18m at 0.90% V2O5, 2.01% Pb, 0.65% Zn from 207m in ABD015
o Includes 19m at 1.25% V2O5, 2.73% Pb, 0.878% Zn from 230m
Hole ABRCD016 was drilled on the margin of the existing resource targeting possible up dip extensions. The hole intersected multiple zones of dolomite breccia with minor descloizite mineralisation between 151m and 266m, an interval of 115m. Best intersections include:
- 10.68m at 0.26% V2O5, 0.57% Pb, 0.17% Zn from 167m

-
5.8m at 0.3% V2O5, 0.92% Pb, 0.30% Zn from 203m
-
6.9m at 0.25% V2O5, 0.58% Pb, 0.32% Zn from 216.1m
The current Inferred Mineral Resource of 2.80Mt @ 0.66% V2O5 (vanadium pentoxide), 2.35% Pb (lead), 0.94% Zn (zinc) for Abenab is calculated at a cut-off grade of 0.2% V2O5 (ASX Announcement 31[st] January 2019). These latest intersections within ABD015, which are greater than the cut off grade of 0.2% V2O5, will likely result in an increase in the resource tonnes.

Mine Development Evaluation Drilling Program
The Abenab RC drilling program targeted shallow vanadium mineralisation adjacent to the historic Abenab open pit. This program forms part of a broader study evaluating mining options for the current defined resource including whether the resource will be accessed using an open-pit or underground mining method.
Shallow mineralisation up dip/plunge of the main resource could support a pit cut-back, with the recent discovery of remnant vanadium mineralisation in the southern wall of the pit providing further support. This area was targeted by holes ABRC019 and ABRC020 that intersected zones with visible descloizite. Results from these holes are pending.
Detailed geological mapping is planned to delineate the extent of the remnant vanadium mineralisation in the south wall of the open pit. This will be followed up with channel sampling and potentially further drilling to in-fill coverage around RC holes ABRC019 and ABRC020.

Surface Vanadium Mineralisation Drilling Program
The RC drilling also tested the vanadium mineralisation over a broad area around the pit within the top 1- 2m. This coarse fill material is considered to be vanadium mineralisation from earlier mining operations, but could also contain material from old stockpiles and tails.
The surface vanadium mineralisation has a vanadium grade commonly ranging from 0.1 to 0.3% V2O5 with high grade zones of up to 3m at 0.62% V2O5 in the RC precollar of hole ABRCD016. Evaluation of this mineralisation is underway to possibly form part of the joint venture with GMC (ASX Announcement 8[th] April 2019).
The best intersections from the surface vanadium mineralisation drilling include:
| • | ABRCD016 | 3m @ | 0.62% V2O5 from surface |
|---|---|---|---|
| • | ABRCD017 | 4m @ | 0.37% V2O5 from surface |
| • | ABRC002 | 5m @ | 0.3% V2O5 from surface |
Work Planned
Pending the results from the Phase 1 drilling program at Abenab, the Company anticipates carrying out an additional in-fill drilling program of 5-6 holes to potentially convert the existing JORC 2012 Inferred Mineral Resource to the Indicated category. Phase 2 drilling is planned for Q4 2019.
Further drill testing of the surface vanadium mineralisation around the open pit is planned to supplement the RC drilling already completed. The volume and grade of this material will be estimated to determine if it can be added to the vanadium bearing stockpiles and tails already sampled that form part of the GMC JV. In addition, an auger sampling program is planned to assess the grade of unconstrained tailings that extend from the old processing plant for over a kilometre to the northeast.
Further results from these programs will be reported as they become available.

APPENDIX 2
JORC 2012 Edition - Section 1 Sampling Techniques and Data
(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 (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 results are based on industry best practices, including sampling, assay methods, and appropriate quality assurance quality control (QAQC) measures. • Reverse Circulation (RC): RC drill chips were collected at 1m intervals via a cone splitter in pre-numbered calico bags. The quantity of sample was monitored by the geologist during drilling. A sample of between 2-4kg was sent to the laboratory. • Diamond Core: The sections of the core that are selected for assaying are marked up and then recorded on a sample sheet for cutting and sampling. Samples of HQ core are cut in quarters along the axis of the core using a diamond core saw. |
| 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). |
• RC drilling was conducted using a face sampling hammer, with all holes drilled a -60 degrees. • Diamond drilling was conducted in HQ mode. Diamond holes were either drilled from surface or from a RC pre-collar. |

|---|---|---|
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • 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. |
• RC sample recovery is monitored by the field geologist. Low sample recoveries are recorded on the drill log. The geologist is present during drilling to monitor the sample recovery process. There were no significant sample recovery issues encountered during the drilling program. • Diamond core recoveries are recorded on the geological log. |
| 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. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. |
• All logging is completed according to industry best practice. • RC chips are logged at 1m intervals using a representative sample of the drill chips. Logging records include lithology, alteration, mineralisation, colour and structure. • Diamond core is logged with lithology, alteration, mineralisation, veining and structure recorded for all holes. |
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • 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. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
• For all sample types, the nature, quality and appropriateness of the sample preparation technique is considered adequate as per industry best practice. • RC samples of 2-4kg are collected at 1m intervals using a cone splitter. The sample size is appropriate for the style of mineralisation and the grain size of the material being sampled. • Diamond core was cut into quarters using a core saw. Quarter core is appropriate for the style of mineralisation. • RC samples are dried at the laboratory and then pulverised to 95% passing 105 microns. Diamond core is dry crushed to a nominal -3mm and thenpulverised to 95%passing105 microns. |
| Quality of assay data |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered |

partial or total. • 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 (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
where a pulp sample is prepared. The pulp samples are then transported to Intertek in Perth Australia for analysis. • Pulp sample(s) have been digested with a mixture of four Acids including Hydrofluoric, Nitric, Hydrochloric and Perchloric Acids for a total digest. • V, Cu, Pb, Zn, As have been determined by Inductively Coupled Plasma (ICP) Mass Spectrometry. • A Field Standard, Duplicate or Blank is inserted every 10 samples. The Laboratory inserts its own standards and blanks at random intervals, but several are inserted per batch regardless of the size of the batch. |
| 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. |
• All significant intercepts are reviewed and confirmed by at least two senior personnel before release to the market_._ • No adjustments are made to the raw assay data. Data is imported directly to Datashed in raw original format. • All data are validated using the QAQCR validation tool with Datashed. Visual validations are then carried out by senior staff members. |
| 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. |
• All drill hole collars were located with a hand held GPS with a accuracy of +/-5m. At the completion of the drilling program all holes will be surveyed by DGPS. • Downhole surveys were taken at 30m intervals using a Reflex single shot camera. The camera records the azimuth and dip of the hole. • The survey co-ordinates are UTM34 South. |

|---|---|---|
| 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. |
• Data spacing and distribution used to determine geological continuity is dependent on the deposit type and style under consideration. Where a mineral resource is estimated, the appropriate data spacing and density is decided and reported by the competent person. • For mineral resource estimations, grades are estimated on composited assay data. The composite length is chosen based on the statistical average, usually 1m. Sample compositing is never applied to interval calculations reported to market. A sample length weighted interval is calculated as per industry bestpractice. |
| 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. |
• Orientation of sampling is as unbiased as possible based on the dominating mineralised structures and interpretation of the deposit geometry. • If structure and geometry is not well understood, sampling is orientated to be perpendicular to the general strike of stratigraphyand/or regional structure. |
| Sample security |
• The measures taken to ensure sample security. | • All samples remain in the custody of company geologists, and are fully supervised from point of field collection to laboratory drop-off. |
| Audits or reviews |
• The results of any audits or reviews of sampling techniques and data. | • None yet undertaken for this dataset |

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 Abenab Mine located on EPL5496 near Grootfontein in Namibia. EPL5496 is held by Huab Energy Pty Ltd a Namibian subsidiary of Golden Deeps Limited. The tenement expired on the 6thApril 2019 and is subject to a renewal application which is pending. • The Government of Namibia has a 3% royalty on any base metal production. • There are no material issues, native title or environmental constraints known to GED which may be deemed an impediment to the continuityof EPL5496. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. | • The Abenab V-Pb-Zn deposits were exploited between 1921 and 1958. The Abenab area attracted periodic attention from the South West Africa Company Ltd (SWACo) and the Tsumeb Corporation Limited (TCL) from the late 1960s to the 1990s. A combined exploration venture between the Japanese International Cooperation Agency (JICA) and Metals Mining Agency of Japan (MMAJ) conducted an extensive regional program between 1995 and 1998 focussed on the discovery of Tsumeb-style mineralisation. AVZ, through it’s Namibian subsidiary Eris Mining Pty Ltd, acquired EPL4416 over the Abenab Mine area in October 2010. Diamond drilling was performed to the north and northwest of the Abenab Pipe area in 2011 and 2012. |
| Geology | • Deposit type, geological setting and style of mineralisation. | • The Abenab and Abenab West mines are stratigraphically located in the Maieberg Formation (Tsumeb Subgroup of the Otavi Group) in the Otavi Mountain Land. The Abenab Pipe straddles the Abenab Fault a ENE-WSW trendingstructure |

| interpreted to be a thrust fault. Three unique styles of mineralisation are represented in the Abenab and Abenab West area: primary carbonate -hosted lead-zinc, late hydrothermal zinc mineralisation and supergene vanadium bearing collapse breccia. The Abenab Pipe is a complex, circular collapse breccia bodydeveloped on the contact of footwallplatylimestone. |

| 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 (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. • A nominal low-grade cut-off of 0.2% V2O5is used with a maximum internal dilution of 1m for reporting of results. |
| Relationship between |
• These relationships are particularly important in the reporting of Exploration Results. |
• Higher grade mineralisation at Abenab is within moderately steep northwest dipping planes (~60 degrees) related to |

| mineralisation widths and intercept lengths |
• 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’). |
bedding. These zones are within an approximately cylindrical, steeply plunging breccia complex. • Drilling was conducted to intersect the mineralised zones at a high angle accept where limited access required a small number of RC holes to be drilled at a more oblique angle to the zones. |
|---|---|---|
| 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 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. |
• Relevant assay results from the reported intervals are provided in Appendix 1. |
| 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. |
• Additional in-fill drilling is planned to upgrade the Mineral Resource from the Inferred category to Indicated. |
