ASX RELEASE
Further significant uranium results from exploration at Mkuju in Tanzania; diamond rig mobilising
Highlights
- Stage 1 drilling up to 3,000m and associated rock chip and soil sampling exploration program continues at the Mkuju Uranium Project, in southern Tanzania has returned further high grade U3O8 results including:
MKGS056(soil) 652ppm U3O8
MKGS056(rock chip) 1,344ppm U3O8
MKGS057(rock chip) 549ppm U3O8
-
Mkuju comprises a 730sq km licence area immediately adjacent to the world class Russian-owned Nyota uranium project.
-
A hand-held spectrometer is also being used as part of the Mkuju program and is producing highly elevated radiation readings in and around the same sample areas.
-
These results provide further confirmation of potentially significant uranium mineralisation across the historical radiometric survey conducted over the Mkuju Project area.
-
Diamond drilling rig is now at being mobilised towards the first drill hole location – planned drilling pending weather and access conditions before end of 2023.
Cautionary Statement
The Company uses a Delta Olympus portable hand-held pXRF analyzer and an RS230 gamma ray spectrometer to screen all samples for mineralisation before submitting samples to the lab for assay. This allows for some understanding of the distribution of mineralisation prior to sampling to better ensure that samples submitted for analysis are representative of the type and style of mineralisation. The hand-held XRF and spectrometer units provide confirmation that mineralisation is present

however it is not an accurate determination of the elemental concentration within the sample anlaysed. Limitations include: very small analysis window, possible inhomogeneous distribution of mineralisation, analytical penetration depth, possible effects from irregular rock surfaces. Accordingly, results obtained from the hand-held pXRF and spectrometer units are indicative only and may not be representative of elemental concentration within the material sampled. The pXRF and spectrometer readings published in this release are subject to confirmation by chemical analysis from an independent laboratory.
AuKing Mining Limited (ASX: AKN) continues to identify significant soil and rock samples as part of its Stage 1 exploration and drilling program at the Mkuju Uranium Project in southern Tanzania, as diamond drilling is about to commence.
AuKing’s CEO, Mr Paul Williams, said Mkuju was emerging as a possible major extension of the world class nearby Nyota Uranium Project that was sold by previous owner Mantra Resources in 2011 for $1.16Bn.
“We are pleased to be mobilizing a diamond rig able to commence a drilling program at Mkuju in order to test the extent of mineralization to depths of at least 100m. With the wet season forecast to commence in December, we are aiming to drill as many diamond holes as possible over the next few weeks,” Mr Williams said.
“Off the back of the initial results reported in October, it is pleasing to see further significant results from soil and rock chip sampling activities. These results continue to demonstrate a correlation with the historical Mantra radiometric anomaly. We will continue to carry out preliminary pXRF and spectrometer measurements on the drilling and other samples prior to their dispatch for assay,” he said.

Table 1 – Mkuju Soil and Rock Chip Sample Results
-
These highlighted results continue to demonstrate a close correlation with the radiometric survey undertaken by Mantra Resources Limited in 2007 – thereby leaving open a significant prospective area for future drilling activities; and
-
Shallow drilling with the auger drilling rig continues to be hampered by technical faults, although work continues to bring this rig up to steady operating condition – thereby allowing drill holes up to around 30m to be conducted in less accessible areas at Mkuju.
Mobilising diamond rig
AuKing has mobilized a track-mounted diamond drilling rig to carry out a short estimated 600m drilling program at Mkuju prior to the end of the year. The aim of the program will be to test for uranium mineralization at depths of a maximum 100m. Certain high priority holes have been targeted for this activity, based on the rock chip, soil sampling and shallow auger drilling exploration activities that have been conducted at Mkuju over the past two months. Initial pXRF and spectrometer results on the diamond drill core samples should be available almost immediately.

Section 1 Sampling Techniques and Data
| 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 0.5 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. |
• Rock chip sampling was undertaken over selected areas on both a visual basis and with the use of a handheld spectrometer (RS230) to confirm the geological interpretation. • Soil samples were collected over specific target areas over a nominal 200m spacing. • The rock chip and soil samples were analysed using a handheld Olympus Delta XRF unit and a handheld RS230 Spectrometer and have been reported in Annexure A of the Report. |
| 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). |

• Rock chip and soil sampling was complete over a variety of areas which resulted in considerable variation in the sample spacing and orientation. • Rock chip and soil samples targeted radiometric anomalies. |
| 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. |
• No orientation bias was considered. |

Section 2 Reporting of Exploration Results
| 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 license to operate in the area. |
• The Mkuju project is located on PL 12184, PL12185, PL12186, PL12187, PL12189, PL12192, and PL12485 and all the tenements are in good standing. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• MRU completed a high-resolution helicopter- borne radiometric survey over the entire Mkuju River Project area in mid-2007 which resulted in the identification of several uranium anomalies requiring field evaluation. Geological mapping, ground radiometrics and trenching was completed on various target areas. Although preliminary in nature, the field observations were positive with visible uranium mineralisation being recorded in trenches at a number of the targets. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The regional geology is dominated by Karoo Basin siltstone and sandstone sediments. • The mineralisation is interpreted to be analogous to ‘roll-front’ uranium deposits, specifically hosted in muti-stacked Karoo Basin sandstone and siltstone sequences. |
| Drill hole information |
• A summary of all information material to the under-standing 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 • 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. _ |
• No drilling information provided. • The rock chip and soil sample results have been reported in Annexure A of the Report. |
| 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. |
• No specific intervals are being reported. • Metal equivalent values have not been used. |
| Relationship between mineralisation widths and |
• 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. |
• No relationship between mineralisation widths and sample size or length. |
10

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| intercept lengths |
• 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’). |
|
| 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. |
• Relevant diagrams have been included within the main body of text. |
| Balanced Reporting |
• 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. • 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. |
• Anomalous XRF readings have been identified at Mkuju, these samples will be sent to the laboratory for an accredited assay, where the results will be tabulated for release. • XRF and spectrometer readings should be considered a guide only. • This reporting method has been deemed appropriate for this stage of the project. |
| 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 substantive data exists. |
| 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. _ |
• Once assay results have been received and reviewed, further drilling and geophysical work will be considered to assess the potential of the Mkuju project. |
