Kairos Minerals Limited (‘KAI’) Managing Director, Dr Peter Turner said “The discovery of spodumene pegmatites on our tenements in a World-class spodumene pegmatite district is highly significant for Kairos.
Highlights
- Spodumene Pegmatite samples have been discovered during routine earthmoving activities next to the flagship Mt York Gold Deposit
- Spodumene (lithium pyroxene) is a highly sought after critical raw material used in the manufacture of rechargeable Electric Vehicle (EV) batteries
- Five pegmatite samples from ‘Lucky Sump’ analysed at Corescan Pty Ltd in WA found to contain spodumene in association with beryl, garnet and micas
- Spodumene pegmatites are part of a larger interpreted dyke swarm at Mt York
- Samples will be sent for multi-element analysis to determine their lithium grade
“It appears that these samples may be part of a larger pegmatite dyke swarm that is largely under cover.
“Spodumene pegmatites are rare in Australia and this discovery indicates we are in a fertile lithium-caesium-tantalum (LCT) district with potentially significant upside.
“Whilst we wait for the chemical analysis from the laboratory for these samples, drilling activities at the Lucky Sump lithium discovery will be prioritised as part of the large programme planned for the Mt York Gold Project”.

Host rocks to the pegmatites appear to be basaltic-gabbroic rocks. The pegmatite samples have been excavated from their source below the sump and are not considered transported.

EIS Funding of $180,000 Awarded for Drilling at Caligula, a Significant Copper Target at the Arkun Project, WA
- Co-funding of up to $180,000 awarded under the WA Government’s EIS scheme to drill the large and significant Caligula copper target identified in soil geochemistry data and Mobile Magneto-Telluric (MMT) data.
- Caligula comprises a 5 km by 1 km soil geochemistry anomaly containing copper-silver-cobalt+/- tellurium-bismuth-molybdenum associated with numerous conductors identified in the MMT data that may represent disseminated or massive sulphides.
- Infill and extensional soil geochemistry surveys have been completed to help define specific drill targets with assays due this Quarter.
- The statutory approvals process for a drill programme has now commenced.
- The aircore drill programme at the Hyperion Prospect, which forms part of IPT’s broader Arkun Project, has been completed. Hand-held XRF data is being interpreted to help select samples for assaying, with results expected later this Quarter.
The Caligula prospect comprises a large soil geochemistry anomaly that is coincident with several significant conductors identified in helicopter-borne Mobile Magneto-Telluric (MMT) data that may represent disseminated or massive sulphides (ASX Releases 9th August 2023 and January 24th 2024).
Caligula is 15 km west of the Hyperion Rare Earth Element prospect anomaly, where an aircore drill programme was recently completed (ASX Releases January 4th 2024 and April 19th 2024). The Arkun project was also recently expanded with three new tenement applications (Figure 1 and ASX Release March 14th 2024).
Impact Minerals’ Managing Director, Dr Mike Jones, said, “This award validates our exploration programmes at Arkun over the past few years. Caligula is one of many geochemical and geophysical targets we have at the project and so the information we will gain from the proposed drill programme will add immensely to our knowledge of this poorly exposed and poorly explored area. We will now start the statutory approvals process for the drilling. We have just completed our maiden drill programme at Hyperion to test for Rare Earth Elements and are interpreting the handheld XRF data to select samples for assaying, and we are looking forward to those results”.

Soil Geochemistry Results
The Caligula prospect comprises an area of anomalous copper-in-soils that extends over about 5,000 metres north-south and up to at least 2,000 metres east-west. It is open to the east and the southwest (Figure 2). The copper is associated with anomalous silver and cobalt and, in the southern part of the anomaly, also has a strong association with bismuth, tellurium and lesser molybdenum (Figure 2). Details about the soil geochemistry results were included in the ASX Release of January 24th 2024.

Orroroo Uranium Project, South Australia
Norfolk Metals Ltd (Norfolk or the Company) is pleased to advise the maiden drill program was completed with a further 5 holes drilled across EL6552 being drilled in Phase 2 of the program in January 2024, taking the total number of holes completed in the maiden program to seventeen (17) (Figure 1). Phase 2 of the program sought to test the palaeochannel model at the Wongway Creek Target (formerly Target 1) where suitable drill access was available. A total of three (3) holes were drilled along the river traverse of the Wongway Creek Target testing both upstream and downstream regions. One (1) hole was drilled downstream of the No Name Creek Target (formerly Target 3) as well as the Rankin Rd Target (formerly Target 4). The completion of the maiden drill program has successfully delineated uranium in ten (10) of the seventeen (17) holes providing data for the Company to further develop a geological model of the Walloway Basin (Figure 3). Most importantly, the interpreted uranium bearing floodplain intersected upstream of Wongway Creek gives Norfolk confidence in the palaeochannel model and future exploration efforts can be planned accordingly. Peak grade of 796ppm pU308 was intersected in ORMR007.
*peak grade(s) noted are the direct detection of pU308 over a 0.02m interval by Prompt Fission Neutron downhole logging within a composite intersection with a cut-off grade greater than 100ppm pU308.

Floodplain Interpretation
The pre-drilling model was targeting the presence of prospective palaeochannels approximately 100 to 150 metres to the south of the modern-day creeks associated with uranium intersected in historical Linc Energy Wells. Drilling results from Phase 1 indicated that the uranium in the Linc Energy Wells appeared to be associated with a secondary permeability created by downward displacement of the sediments resulting from basement faulting or soft sediment deformation. Phase 2 drilling continued to test the targeted prospective palaeochannels located to the south of the modern-day creeks at closer than expected distance of 50m. Younger palaeochannels were seen south of the modern-day creeks in ORMR004 (Walloway Creek Target) and ORMR016 (Rankin Rd Target) at the base of the regolith. This further supports the model of palaeochannels occurring south of the modern-day creeks due to a change in regional slope.
Drillhole ORMR015A was drilled 50m south of the modern-day creek at Wongway Creek Target. Drilling upstream from previous holes enabled easier location of the targeted prospective and potentially wider palaeochannel. This hole encountered what appears to be a silt dominated floodplain with minor gravel and two elevated gamma anomalies signifying uranium towards the top of this unit as well as the base of this unit (Figure 2). This unit appears to be the middle section of a palaeochannel between the sand and gravel dominated incising part of a palaeochannel and the clay dominated edge of a floodplain.
