Aruma Resources Limited (ASX: AAJ) (Aruma or the Company) is pleased to announce initial assay results from 37 holes of the 40 hole 4,518m maiden reverse circulation (RC) drilling program at the Saltwater Gold Project, in the Pilbara region of Western Australia.
The Company’s maiden drilling program at Saltwater focused on outcropping areas on the western end of the Saltwater Ring Structure, a large 60km[2] magnetic ring structure that sits within E52/3818 at Saltwater, as shown in Figure 1.
Drilling was conducted over four short, closer-spaced lines (shown in Figure 2) which targeted the anomalous western area of the Saltwater Ring Structure.
The program also comprised wider-spaced (regional) longer lines, to the east, which targeted the covered ring structure/splay. Nine holes totaling 900m, in two lines of drilling, were completed in this area, as shown in Figure 2.
Intersections grading up to 1.26g/t gold have been received from drilling at the historic Saltwater mining area. The nine wider-spaced extension holes have identified a significant supergene blanket in excess of 200 metres wide.

The results are highly encouraging and extend over a strike length of 4 kilometres, and indicate the discovery of a possible new gold camp on the ring structure at Saltwater. This ring structure will be investigated by further drilling.
Significant drill intersections, above >0.3g/t, are shown in Table 1. Holes 27-29 are yet to be received, and will be reported when available.
Aruma Managing Director Peter Schwann stated:
"The intersections from our maiden drilling program at the Saltwater Project are highly encouraging, and are the highest to date in the area, and deliver confirmation of our exploration model, and the potential size of the system. The large, 60km[2] , Saltwater magnetic ring structure will be further tested to define possible resources in the next phase of drilling."

Figure 2: Drill targets from recently completed maiden drill program at the Saltwater project on TMI magnetics, showing the target Duck Creek-Mt McGrath stratigraphy as the shaded anticline.
Figure 2 shows the rationale behind the recently completed Saltwater drilling, with the western drill lines located over the historic gold area, and the eastern lines positioned over the splay and Nanjilgardy Fault, under cover. The western splay coincides with AVRC24 anomaly, alteration and historic nuggets. The eastern splay targeted areas of deep weathering and paleochannels.
The close-spaced drilling targeted old workings at the historic Saltwater mining area within the recently identified and prospective Mt McGrath Formation, which hosts Mt Olympus Gold Mine.
The wider-spaced drilling targeted the extension of the contact and structure under cover some 3km east.
The supergene blanket seen in the East Lines in Figure 3 is located almost 4km from the Saltwater cluster and highlights the potential for a significant system - with the intersection of 4m at 0.47g/t in hole SRC 32.

About the Saltwater Gold Project
The Saltwater Gold Project has eight granted Exploration Licences for a total area of 736km[2] . The Project is located approximately 100 kilometres south-west of the regional mining centre of Newman.
The Project area covers a strike extent of more than 65km of the highly significant Nanjilgardy fault, the same regional structure reported as the primary source of gold mineralisation at Northern Star Resources’ (ASX: NST) Paulsens Gold Mine and the Mt Olympus Gold Mine in the region.
The original geological mapping identified only Ashburton Formation but re-interpretation from mapping outcrop and magnetics suggested that there was Duck Creek Dolomite, Mt McGrath and Cheela Springs Basalt underneath and domed up through the Ashburton Formation. This is what forms the Saltwater Ring Structure and is the same stratigraphy as Mt Olympus to the west.

Section 1 Sampling Techniques and Data
The following data is in relation to Historic Drill Holes in the announcement and the individual holes are listed with the relative Minedex A Report number.
| Criteria | JORC Code explanation Commentary |
JORC Code explanation Commentary |
|---|---|---|
| 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. • 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 (e.g. submarine nodules) may warrant disclosure of detailed information. |
•RC drill samples are taken from various depth holes and sampled in 1m or 4 m intervals •Samples from depth down hole. •Samples were spear sampled for composites and the 1m samples left on site |
| Drilling techniques |
• Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or _other type, whether core is oriented and ifso, by what method, etc.). _ |
•Drilling was done with RC rigs using industry standard sampling methods. |
| 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/gainof fine/coarse material. |
•The best endeavors were used to ensure sample recovery and splitting gave the best quality possible. Sample weights were recorded and displayed good consistency with the majority between 0.73 to 3kg. |
| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate |
•All samples were logged geologically and qualitatively. |
| Criteria | JORC Code explanation Commentary |
JORC Code explanation Commentary |
|---|---|---|
| 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. _ |
||
| 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. _ |
•All samples rotary split and noted wet or dry. Where sample quality precluded riffle splitting, the material was tube sampled. •The sample size satisfied the Gy size requirements. |
| Quality of assay data and laboratory tests |
• 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. _ |
•Laboratory standards and methods are industry standards. •Duplicate samples were not taken as any anomalous holes would be assayed in the 1m splits |
| 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 intersections were inspected by at least two competent and relevant geologists. •No holes were twinned as this is not required in grass roots exploration. |
| Criteria | JORC Code explanation Commentary |
JORC Code explanation Commentary |
|---|---|---|
| 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. |
•Initial hole layout was by GPS. Australian Standard licenced surveyors were used to position the drill holes where required. •All locations are GDA94 |
| 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. |
•The spacing was done to look at a previous geochemical anomaly and identify bedrock •The Saltwater holes were nominally 50m apart and the regional Eastern holes 100m apart •Compositing was done on regional Eastern holes in 4m intervals and will be re-assayed if greater that 0.2 g/t Au |
| 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. |

• 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. _ |
•All drill holes tabled, and information from holes quoted with Relevant Minedex A Report Number. |
| 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. _ |
•Drill holes are oriented to get intersections as close to true widths as possible. •Aggregate intercepts were used on historical drilling with a nominal cut off of the industry standard of 0.1g/t Au. •Metal equivalents never used. |
| 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’). _ |
•Section used in the AAJ announcement is diagrammatic in nature and will be upgraded when composites are re-assayed in 1m intervals |
