Astute Metals NL (ASX: ASE) (“ASE”, “Astute” or “the Company”) is pleased to advise that recently completed geological mapping and rock chip sampling at the 100%-owned Red Mountain Lithium Project in Nevada, USA has identified a new zone of lithium bearing clay-rich rocks (shown as the Dark green ‘Unit J’ in Figures 1-3) with lithium grades of up to 2,100ppm lithium.
Key Highlights
- Detailed geological mapping completed by consulting expert Professor Phillip Gans of the University of California Santa Barbara.
- Mapping identifies two priority clay-rich and lithium- hosting rock units at Red Mountain.
- Additional rock-chip sampling within ‘Unit J’ identifies a broad zone of mineralisation grading up to 2,100ppm Li.
- Mapped as the most clay-rich rock type. ‘Unit J’ has only been tested by one drill hole, indicating excellent upside.
- Continuous ‘Unit O’ trending approximately north-south through project will underpin the upcoming Exploration Target.
Unit J is a claystone and siltstone dominated rock type located in the west of the Red Mountain Project area which was identified as part of detailed geological mapping undertaken by consultant geologist Professor Phillip Gans of the University of California Santa Barbara. Professor Gans identified Unit J as the most clay-rich rock unit at the Project and recommended a targeted sampling campaign to establish the presence of lithium mineralisation. Subsequently a total of 38 sub-crop and outcrop samples were taken over an area of 800 x 500m of Unit J (Figure 1), with excellent assay results returned from 13 samples grading 1,000ppm lithium or greater. The sampling revealed outstanding exploration potential in this previously unsampled part of the project.
The mapping also identified two priority rock units for future drill targeting – Unit O and the previously mentioned Unit J. Unit O (shown in pale green in Figures 1-3) is dominated by silt and sandstone with clay-rich horizons, is interpreted to be continuous over a 7.8km extent across the Project, and has been tested by 12 of the 13 holes drilled to date, each of which has intersected strong lithium mineralisation7.
The continuous nature of Unit O will underpin a maiden Exploration Target for the Project and inform the drill targeting strategy for the first half of 2025, as the Company advances toward a Maiden Mineral Resource Estimate in the second half.
Astute Chairman, Tony Leibowitz, said:
“With the advice of expert independent consultants, we are continuing to systematically progress the Red Mountain Project. The identification of a new high-grade lithium-bearing unit increases the project’s potential, while the enhanced geological understanding allows the calculation of an Exploration Target, as well as contributes to de-risking of the upcoming drilling campaign, paving the way for a maiden Mineral Resource Estimate in the second half of 2025”

Background
Located in central-eastern Nevada (Figure 4), adjacent to the Grand Army of the Republic Highway (Route 6), which links the regional mining towns of Ely and Tonopah. the Red Mountain Project was staked by Astute in August 2023.
The Project area has broad mapped tertiary lacustrine (lake) sedimentary rocks known locally as the Horse Camp Formation2. Elsewhere in the state of Nevada, equivalent rocks host large lithium deposits (see Figure 4) such as Lithium Americas’ (NYSE: LAC) 62.1Mt LCE Thacker Pass Project2 and American Lithium (TSX.V: LI) 9.79Mt LCE TLC Lithium Project3.
Astute has completed substantial surface sampling campaigns at Red Mountain, which indicate widespread lithium anomalism in soils and confirmed lithium mineralisation in bedrock with some exceptional grades of up to 4,150ppm Li1,6 (Figures 1 and 3).
A total of 13 RC and diamond drill holes have been drilled at the project for a combined 1,944.72m. Both campaigns were highly successful with strong lithium mineralisation intersected in every hole drilled7.
Scoping leachability testwork on mineralised material from Red Mountain indicates high leachability of lithium of up to 98%, varying with temperature, acid strength and leaching duration8.

Drilling Commences at the Kanowna East Gold Project
Key Points
- High impact drilling has commenced at Kanowna East, targeting basement gold systems at the Western Tiger and Little Lake Prospects, only 25kms NE of Kalgoorlie.
- Program designed to test prospective structural settings and alteration zones along the Reidy Fault and newly recognised northeast gravity trends.
- Targeting the potential source of widespread paleochannel gold occurrences identified from historical drilling.
- Strong cash position of ~$3 million ensures a well-funded campaign and supports strategic exploration momentum.
Figure 1: Ragland Drilling RC Drill Rig at AX8’s Little Lake Prospect, Kanowna East Project.
The 2,000m reverse circulation (RC) program is testing structurally controlled, basement- hosted gold targets at the Western Tiger and Little Lake Prospects (Figure 2). These targets have been selected based on structural complexity, geophysical modelling, and geochemical signatures indicative of gold-bearing systems.
Figure 2: Western Tiger & Little Lake geology interpretation with planned RC drill hole locations (green triangles).
At Western Tiger, drilling is focused on the undrilled western margin of a felsic intrusive unit interpreted to have been emplaced along the Reidy Fault. Sericite alteration, arsenic- antimony pathfinder anomalies, and recent structural reinterpretations highlight the area as a priority for potential gold discovery.
At Little Lake, newly processed gravity data has defined northeast-trending features interpreted to intersect northwest fault systems—structural zones commonly associated with gold mineralisation in the Kalgoorlie district. These trends correlate with previously intercepted basement-hosted gold and offer a compelling test of the Company’s exploration model.
“Commencing drilling at Kanowna East marks an important milestone in Accelerate’s gold strategy,” commented Chief Executive Officer Luke Meter. “We’re testing targets with geological signatures consistent with major orogenic gold systems in the Eastern Goldfields and success could substantially enhance the value of our gold portfolio near Kalgoorlie.”
With a strong financial position, Accelerate remains well-funded to execute its exploration strategy across multiple growth-stage gold assets in WA.
The Company looks forward to updating shareholders as drilling progresses and assays become available.

Extensions and New Zones of High Grade Tin at Bygoo North
HIGHLIGHTS
- Scale of Bygoo Tin Project continues to grow with the discovery of new zones of tin mineralisation during the Company’s second RC drilling campaign
- Very broad zone of tin mineralisation at the Stewart’s Lode extended along strike with:
- 118m @ 0.32% Sn from 44m in BRC015 (unconstrained internal dilution); including
- 29m @ 0.53% Sn from 44m, including 8m @ 1.17% Sn from 45m
- 12m @ 0.45% Sn from 116m; and
- 28m @ 0.52% Sn from 146m
- Caspin’s maiden drilling at the Smith’s Lode returns further high-grade tin with:
- 16m @ 0.68% Sn from 49m (BRC013); including
- 5m @ 1.73% Sn & 1.45% Cu from 53m;
- Drilling identifies a further new zone of mineralisation named ‘Radius’, between Dumbrell’s and Smith’s, with:
- 16m @ 0.48% Sn from 124m (BRC016); including
- 2m @ 2.05% Sn & 0.37% Cu from 128m
- Wide zones and high-grade tin mineralisation now drilled over +1,000m of granite contact zone with large gaps in drilling and open along strike.
- High resolution aerial magnetic survey covering ~800km2 to commence shortly
Caspin’s Managing Director, Mr Greg Miles, commented “These results are an exciting epilogue to our maiden drilling program at the Bygoo Project. We are delighted with intersecting 16m @ 0.68% Sn in our first drill hole at Smith’s, including a high-grade zone of 5m @ 1.73% Sn, coupled with 1.45% Cu, the highest-grade copper result by Caspin to date. Another 100m-plus intersection of tin mineralisation at Stewart’s also confirms continuity of ‘bulk’ mineralisation, at very shallow depths. And finally, a new zone of tin mineralisation at ‘Radius’ result demonstrates verifies Caspin’s geological model and growing understanding of key controls to tin mineralisation.
“Most importantly, we now recognise the tin mineralisation potential over greater than 1,000m of shallow granite contact strike at Bygoo North. Drilling is quickly demonstrating that Bygoo North has excellent potential to grow into a tin project with substantial scale. Drilling will continue to target new zones of tin mineralisation and extensions of known areas of shallow tin mineralisation along strike.”
Since acquiring the project, the Company has invested considerable time to understand the geology and controls on mineralisation at Bygoo North. Using the previous exploration data as a base and steadily importing other legacy data such as drilling from the 1970s, the Company is developing a new geological model for the prospect. The Ardlethan Granite contact can now be traced over 1,000m at the prospect, with greisen-style mineralisation developed variably along its entirety (Figure 1).
Figure 1. Location plan of mineralisation and relationship to granite contact at Bygoo North, with significant intercepts. The prospective granite horizon represents the potential for greisen mineralisation on the granite contact to approximately 100m below surface.
These latest results provide further evidence that mineralisation is constrained only by drilling. There are obvious additional drill targets for further exploration. A planned high-resolution aerial magnetic survey, commencing in the following weeks, will further assist refinement of the geological model and hence the targeting process, particularly the several kilometres of untested granite contact to the north and south.
