The maiden drilling program at Jameson kicked off in late
Infill drilling at the Malinda Prospect continues to demonstrate quality lithium intercepts from surface with the dominant lithium bearing mineral being spodumene. The two holes highlighted above YRRD471 and JREX002 represent the two best intercepts to date at Yinnetharra.
Commenting on the results Managing Director,
"Malinda continues to provide us with excellent lithium results that confirm our existing resource and build our confidence in the geology. Particularly a very wide intercept in YRRD471 which will add significant lithium metal to an important part of the M1 resource.
The first hole assay results from the Jameson Prospect JREX002 has delivered fair reward for the Team's effort, with some of the coarsest visual spodumene seen to date at Yinnetharra over a very wide downhole interval, and individual assays in excess of 4% Li2O."
Yinnetharra Exploration

The maiden drill result from the Jameson prospect is very encouraging. Lithium anomalism at Jameson is present as a coherent soil geochemistry anomaly >150ppm Li2O approximately 600m long. Drilling orientations at Jameson were chosen to intercept the regional trend of stratigraphy in a perpendicular manner.
Visual logging of the RC chips indicates spodumene is the only Li bearing mineral phase observed to date (Figures 3 & 4*), with the remainder of the pegmatite composed of quartz, feldspar, and minor apatite and beryl. Assay results support this observation.
Geological interpretation of the area is ongoing with more information becoming available through drilling and mapping. Orientations of mineralised pegmatite are not known at this stage, this drilling intercept reported may be oblique to the dip and dip direction of the mineralised pegmatite and not indicative of the true width of mineralisation.
Drilling is ongoing at Jameson, further results will be released in due course.
Drilling completed to date at Malinda has demonstrated quality lithium intercepts from surface with the dominant lithium bearing mineral being spodumene. Recent highlights can be seen below in Table 1* and Figure 5*, with a full list of recent results in Appendix 3*. Along strike extensions to M36 have been found as well as up dip extensions of M47 as indicated in Figure 5*.
Lithium resources are largely present in 3 main pegmatites at Malinda from surface to a depth of >300m.
Metallurgical test work is ongoing with initial results demonstrating the potential for high recovery of spodumene to high grade low impurity concentrates.
Mt Ida Update
The Mt Ida project is a "shovel ready" permitted lithium and gold project in the Goldfields region of
Delta is progressing multiple options to monetise the gold assets at Mt Ida in conjunction with remodelling and optimising the resources, and advancing open pit and underground mining studies.
A significant amount of near surface high grade gold was discovered and defined by Delta in 2023 (Figure 7*). The Baldock 086 lode (
The Baldock 086 Lode has been grade control drilled to a nominal 10m x 10m spacing. As part of this preparatory work a comprehensive metallurgical test work program has been undertaken and results received covering the Baldock 086 Lode, which is contained within the volume of the fully permitted
Gold extraction rates for each composite ore type are tabulated below in Table 2. A range of 91.4-99.7% recovery was achieved in an 8hr residence time, with 44-63% of the gold able to be recovered with a gravity circuit. Cyanide consumption was very low for the master composites ranging from 0.5-1.25 kg/t. Copper grades ranged from 502-1,110ppm and returned expected low cyanide solubilities.
