*PGE: Platinum Group Elements – palladium (Pd) and platinum (Pt)
Dalaroo Metals Ltd ( ASX: DAL , “Dalaroo” or “Company”) is pleased to report encouraging results from its initial wide-spaced, first pass geochemical sampling programme from its Namban Project located ~ 150km north-northeast of Perth and adjacent to the regional centre of Moora in Western Australia (Figure 1 and 4).
The auger geochemical sampling programme totalled 81 samples covering an area of 1.0km by 1.5km. No modern systematic exploration has been undertaken over this area of the Archaean age Jimperding Metamporhic Belt prior to this very recent work by Dalaroo.
The Cattady PGE-Ni-Cu Anomaly is defined by sample spacing of 200 X 100m. Multi-element assays have delineated the Cattady anomaly covering an area of 1.0 X 0.25km with a peak Pd value of up to 82ppb associated with anomalous Pt values of up to 15 ppb for combined PGE value of 97ppb (Figures 2 and 3). Surrounding the geochemical anomaly the Pd and Pt values are complemented by values of up to 642ppm Ni and 226ppm Cu (Figure 3).
“The anomaly coincides with a broad residual lateritised topographic high, trending in a northsouth direction. Residual laterite is commonly observed in the Jimperding Metamporhic Belt as the surface expression of underlying mafic and ultramafic lithologies,” said Mr Harjinder Kehal, Managing Director of Dalaroo Metals.

“There is a lot of interest in this emerging PGE-Ni-Cu province and our results confirm the potential of the region and especially with the recent new Julimar 10 Moz Pd-Pt-Ni-Cu discovery, a strategic deposit of critical ‘green metals’ used in the creation, storage and transport of renewable energy,” said Mr Harjinder Kehal, Managing Director of Dalaroo Metals.
Upcoming Exploration Milestones
Infill sampling on a 50 X 50m grid over the Cattady PGE-Ni-Cu anomaly has commenced in December. With the grain harvest nearing completion over the Namban Project area, large areas will now become available for a systematic geochemical sampling programme. Priority sampling will test the north-south strike extent of the Cattady PGE-Ni-Cu anomalous zone. First pass geochemical sampling of additional targets generated from the recent detailed UAV airborne magnetic surveys will follow in early January, 2022.

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 (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 x-ray fluorescence (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. |
No drilling completed by Dalaroo Auger samples collected from 0.6 – 1m depth with 0.5-1kg collected for assay. Magnetic survey locations were measured with a dual frequency GNSS receiver operating in autonomous mode, with x,y,z accuracies accurate to better than 1-2m. Elevations were derived using a laser altimeter. Entire sample is submitted for sample prep and assay A UAV survey was conducted on 50m line spacing and 25m sensor height by Atlas Geophysics using PAS-H100 Rotary Wing helicopter.

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. |
The Namban Project tenements are wholly owned by Dalaroo Metals Limited (Dalaroo) The Project is located 150km north of Perth on freehold land. Tenure in the form of Exploration Licences with standard 5-year expiry dates which may be renewed. The Competent Person is unaware of any impediments to development of these tenements. |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
No known exploration in Archaean age Jimperding Metamporhic Belt, area covered by Proterozoic rocks explored for potash with geological mapping and rock chip sampling. Government DMIRS 200m spaced airborne magnetics and radiometrics data has been included. |
| Geology | Deposit type, geological setting, and style of mineralisation. |
The primary mineralisation style being sought is nickel-copper-PGE (Ni-Cu-PGE) intrusive related deposits such as Julimar |
| Drillhole information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes: • easting and northing of the drillhole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drillhole collar • dip and azimuth of the hole • down hole length and interception depth • hole length.

| 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 (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 drilling results reported. No metal equivalent values have been reported. |
| 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 drillhole angle is known, its nature should be reported. If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (e.g. ‘downhole length, true width not known’). |
No drilling results reported. No drilling results reported. |
| 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 drillhole collar locations and appropriate sectional views. |
Appropriate diagrams are included in the main body of this report. |
| 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. |
Reporting of the magnetic results is considered balanced. |
| 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 additional meaningful and material exploration data has been excluded from this report. |
