⛏️ Kula Gold Limited reports Kaolin results from the RC and diamond drilling programs at the company’s Boomerang Kaolin Prospect (within Kula’s 100% owned Marvel Loch-Airfield Gold Project near Southern Cross) in Western Australia.
- High quality, low impurity Kaolin delineated from pattern drilling.
- Large area, average thickness of 27m, close to surface and includes Halloysite.
- Open in all directions.
- Resource estimation work in progress by HGMC.
- Sedgman conducting metallurgical test work.

Local infrastructure is very good with towns, water supply, power, and new tar road 2km from the prospect (See Figure 2). Commercialisation studies have commenced with the appointment of a Project Manager.
Kula Gold is looking forward to publishing the resource statement, along with further details on the project, logistics, and other commercial aspects in due course.
Figure 1. Cross section through 744,050mE (viewing West) showing %AI₂O₃ within the -45μm size fraction for the Kaolin clay zone, and interpreted base of transported and top of fresh rock boundaries. Location of cross section provided in Figure 3. Note: Results for 21BMRC038 (drilled as a duplicate hole of 21BMRC001) have been greyed out for ease of reading.
The result shows exceptional consistency (Figure 1) of high-quality (% AI₂O₃ in the -45μm size fraction shown) Kaolin with low deleterious elements. Thickness of the Kaolin is up to 57m in vertical depth, with an average vertical thickness of 27m over drillholes covering the 1.7km x 1.6km area. Cover averages a shallow 5m. The extent of Kaolin is open in all directions, with the southwestern most drillhole intersecting a Kaolin zone of 43m true width (22BMRC017 – Figure 3). Table 1 comprises a selection of the best intercepts, with the full list of intercepts provided in Appendix A- Table 2.

Weighted averages¹ of the RC hole intercepts indicates the drilled area yields an average Kaolin thickness of 27m, from which 47.66% reports to the -45μm size fraction, which grades 35.29% AI₂O₃ with low impurities of 0.85% Fe₂O₃ and 0.46% TiO₂. The top of the Kaolin clays is at a depth, on average, of 5m vertically below the surface. Intercepts for all RC holes are presented in Appendix A – Table 2.
Size fractions and assay results confirm the high-quality Kaolin extends over the approximately 1.7km x 1.6km area drilled with consistent AI₂O₃ and low impurities through the -45μm size fraction material. A representative cross section of the geologic profile is provided in Figure 1. A set of drill-interval observed geostatistics, showing low and high assay results and associates standard deviations are presented in Table 3 (Appendix A). The lateral extent of the Kaolin clays remains open in all directions.

An independent JORC 2012 resource estimate is currently being prepared by HGMC (Hyland Geological Mining Consultants).
Halloysite and brightness testing was completed on 3 RC holes with brightness averaging 82% and up to 7% Halloysite (reported previously: ASX release 13 July 2021). Recent discussions with potential customers indicate that brightness and Halloysite will not be considered for immediate us for certain Kaolin based products, therefore test work on these and other components is to be postponed pending any future actual customer requirments.
¹ Abandoned and duplicate drillholes not included in the weighted average calculation.
Density and metallurgical test work from the 120.8m of diamond cor from two diamond drill holes is currently underway and being managed by Sedgman. Density measurement results thus far received outlined an average of 1.9t cubic metre (see Appendix A: Table 4).
