Augustus Minerals (ASX: AUG; “Augustus” or the “Company”) is pleased to advise that a review of all available data for copper mineralisation around the intersection of the Ti-Tree Shear (east-west trending shear) and the Money Intrusion (a major north-south mafic dyke) in the western portion of the tenement package highlights the scale potential of this 8km long x 3km wide predominantly Cu/Au mineralised zone.
Highlights
- Widespread copper/gold anomalism across 4 prospects, including flagship Copper Ridge prospect, covering an area 8km long x 3km wide
- All prospects are hosted inside Leake Spring Metamorphics, the key rock unit attached to the Ti-Tree shear hosting the majority of mineral occurrences regionally
- Better grades from rock chips include;
- 34.90% Cu • 245g/t Au
- 26.00 % Cu • 115g/t Au
- 21.80% Cu • 31.20 g/t Au
- 34 samples with copper grades >1% and 21 samples with grades >1g/t gold
- Historic regional drilling did not target high grade Cu/Au prospects (Crawford Bore and Crawford South) with Copper Ridge and Nicks Bore having no drilling
- Surface mapping and sampling over Copper Ridge has confirmed a 600m long zone of outcropping copper mineralisation
- Nick’s Bore copper in rock chips extends over 3km, with similar geology and appearance to Copper Ridge
- Approved programme of work (PoW’s) from Department in Mines, Industry Regulation and Safety for drill testing
Geology
The Crawford Bore to Copper Ridge (Figures 1,2 and 3) region has excellent exposure of basement geology wrapped over low undulating rises and prominent ridges of saprolite.
Documented polymetallic surface mineralisation with widespread elevation to ore grade concentrations of precious, base and specialty metals (Au, Ag, Cu, Pb, Zn, Mo and Bi) suggests potential for:
- Porphyry Au-Cu-Mo;
- Broken Hill Style mineralisation; or
- Intrusion related copper-gold
Figure 1. Location of Crawford copper-gold prospects at the Ti Tree Project.
History
Early exploration in the 1980’s discovered evidence of copper/gold at surface. By the 1990’s exploration was targeting large tonnage (Broken Hill type) metal mineralisation with the advent of airborne magnetics and radiometrics. Numerous high-grade anomalous rock chips (Table 1) were reported.
Further assessment during the mid-2000’s involved minor drilling and costeaning and despite encouraging results, the project was abandoned. From 2012-2015 Auroch Minerals Ltd conducted further exploration, however the project was terminated due to a decline in market conditions.

Diversification can be key to a profitable mining and exploration strategy. While there's no shortage of companies that have experienced great success by focusing on a single commodity, there's always an element of risk to that approach. There is always the risk that certain commodities will fall in price whilst others rise. Augustus Minerals, a newly listed exploration company on the ASX (AUG) is cognizant of this fact. An exploration company based in Western Australia, Augustus has acquired a 100-percent interest in a land package covering some 3,600 square kilometers in Western Australia's Upper Gascoyne region. Although traditionally known as a source of base metals, gold and uranium, the Gascoyne is rapidly emerging as a prime target for rare earths and lithium discoveries.
As an early mover to the region, Augustus’s vast landholding is highly prospective for lithium, rare earths, copper and gold. Its Ti-Tree project contains 85 kilometers of the Ti Tree and Mingabar shear zones, with extensive, untested, multi-element mineralization and surface anomalies.
The Gascoyne region is a large emerging critical mineral province with several deposits having been discovered in the last few years. These include multiple Ironstone REE discoveries by Dreadnought Resources (ASX:DRE), Hastings Technology's (ASX:HAS) Yangibana Ironstone REE project and Lanthanein Resources' (ASX:LNR) Lyons Ironstone REE project, as well as a large lithium discovery at Delta Lithium's (ASX:DLT) Yinnetharra location.
Directed by a highly experienced management team with extensive knowledge about mining and exploration in the Gascoyne, Augustus's exploration program will focus on more than 50 priority targets already identified by the company. These include potential lithium bearing pegmatites, REE-rich ironstones and shear/porphyry-hosted copper systems. Thus far, the company has completed multiple geophysical surveys and collected more than 15,000 soil samples.
Company Highlights
- Augustus Minerals is an Australian exploration company focused on the highly-prospective Gascoyne region of Western Australia.
- The company has 100 percent ownership of a land package covering 3,600 square kilometers.
- Augustus has identified multiple high-priority lithium, rare earth and copper targets throughout its project, with strong mineralization intersected at multiple locations across multiple commodities.
- Augustus's leadership team has the benefit of significant local knowledge regarding exploration of the Gascoyne province.
Key Asset
Ti Tree Project
Situated in the Shire of Upper Gascoyne and the Shire of Carnarvon, the Ti Tree project displays significant exploration potential for a number of different mineralised styles as well as possibly, multi-commodity discoveries. Spanning a contiguous 3,600 square kilometers, it also has the distinction of being one of the largest properties in the region. Augustus Minerals maintains 100 percent ownership over Ti-Tree, which intersects along the shear of the same name.
The company has identified several high-priority drilling targets along the Ti-Tree and Mingabar structures ready for reverse circulation, diamond or air core drilling.
Highlights:
- Emerging Geological Province: The Gascoyne region displays highly prospective geology and has been the site of multiple rare earth and lithium discoveries in recent years, but has experienced limited historic exploration — making it a prime opportunity for Augustus Minerals.
- Multiple Commodities: Augustus has identified more than 50 significant lithium, rare earth and copper targets. Many of these high-quality targets are ready for drilling.
- Size and Speed: The Ti Tree Project consists of a single coherent block of tenements covering 3,600 square kilometers with 85 kilometers of strike along the Ti-Tree Shear. As an early mover in the region, Augustus was able to gain a considerable advantage in securing this project, into which it has thus far invested $5 million.
- Fertile Geology: Augustus's investment displays the same geology as multiple highly successful neighboring discoveries.
- Mineralization: Current mineral resource targets include:
- 27 rare earth targets across 65 kilometers of strike. All targets display strong thorium radiometric signatures.
- Multiple mafic intrusions with copper-nickel-PGE (platinum group elements) mineralization. The copper resource is both shear-hosted and porphyry-related.
- Elevated lithium stream samples over 10 kilometers of strike length. The target area displays the same geological host rock as the Yinnetharra lithium discovery.
- A narrow, shear vein-hosted gold occurrence with anomalous mineralization displayed in several surrounding areas. The area, known as the Bassit Bore, outcrops at the surface, where visible gold is readily identifiable in hand specimens. Samples collected over 600 meters returned very high gold values.

Unconformity Uranium Drill Targets Identified from 2024 Geophysical Data
Key Highlights
- Final data received and interpretation completed for the ground electromagnetic geophysical surveys from the winter 2024 program at the Marshall and North Millennium projects.
- Several conductive anomalies identified at Marshall, located above and below the unconformity, consistent with regional exploration model.
- Stacked anomalies concurrently with multigenerational geophysical data provides a base to assess the exploration targets and refine drillhole targets.
- The projects are located 15 kilometres from the majority Cameco owned Millennium deposit, and just 40km from the world class McArthur River mine.
- Basin remains funded for the next round of field exploration.
The ground electromagnetic successfully identified 3 main targets which confirms the geological and exploration model. Of note is Target 1 (Figure 1), where modelled EM plates below the unconformity align with a sandstone ZTEM anomaly, which is interpreted to be alteration within sandstone. The identification of these targets is encouraging and consistent with regional trends in the southeastern Athabasca and provides increased confidence in drill hole targeting. Basin is currently reviewing options and priorities of how to progress exploration of these confirmed targets.
Basin’s Managing Director, Pete Moorhouse, commented:
“Conducting ground geophysical surveys on Marshall and North Millennium was a milestone in advancing these underexplored projects in Basin’s uranium portfolio. The form of these anomalies is highly encouraging given the proximity to some of the world’s largest uranium deposits.”
Key results
Following the encouraging conductive anomalism highlighted by the 2023 3D inversion of two historic airborne Electromagnetics (Z‐Tipper Axis) (“ZTEM”) datasets partially covering the current North Millennium and Marshall projects3,4, Basin contracted Discovery International Geophysics5 to carry out ground Stepwise Moving Loop Transient Electromagnetic (‘Ground EM’) surveys on areas of immediate interest within the Projects.
Figure 1 Three main anomalies shown from 2024 ground EM, in plan view (top diagrams) and cross- section looking northeast (bottom diagram). The ground EM anomalies are displayed with the modelled plates against the historical ZTEM data.
The 2024 Ground EM survey data returned six conductive anomaly picks producing three main target areas (Figure 1). The anomalies correlate strongly with the southern edge of the circular ZTEM conductive anomaly at Marshall and the interpreted northern edge of the circular anomaly identified in the historic data. A weaker EM pick was also interpreted centred between the two prominent ZTEM conductivity anomalies.
Three-dimensional modelling using Maxwell produced six electromagnetic conductive plates within the basement stratigraphy, all below the unconformity (Figure 1). The two southeastern plates are clearly aligning with a conductive sandstone ZTEM anomaly identified from the historic data, which is above the interpreted unconformity. This is interpreted as potential basal sandstone alteration proximal to the EM anomalies and constitutes a high-priority drill target area, refer figure 2.

Airborne EM over Multiple Targets on Ti-Tree Project
- Augustus Minerals has contracted UTS Geophysics to conduct a VTEM Max survey over several Copper, Cu-Ni-PGE, Zn-Pb-Ag and Uranium targets along the money Intrusion and within proximity of the prospective 85k long Ti-Tree Shear.
- The surveys will cover:
- The Money Intrusion, prospective for Cu-Ni-PGE mineralisation.
- Copper Ridge and Nics Bore over anomalous Copper Drilling results
- The Coo Creek prospect where drilling by Augustus in 2023 identified strongly anomalous Zn-Pb-Ag mineralisation.
- The Munaballya Well North area which shows potential for economic Uranium mineralisation.
- The surveys will help to advance the untapped potential of the Ti-Tree project to host economic mineralisation of multiple commodities.
Andrew Ford, GM Exploration
“The VTEM survey will provide key targeting data over three highly prospective and different prospects with potential for multiple commodities. Whilst the high prospectivity for copper mineralisation has been well documented, the addition of uranium and Broken Hill base metal style mineralisation highlights the quality of the underexplored Ti-Tree project”.
VTEM
UTS Geophysics has been engaged to conduct a helicopter borne VTEM Max survey comprising 646-line km over three separate survey areas. The system is excellent for locating discrete conductive anomalies as well as mapping lateral and vertical variations in resistivity which helps map structure, alteration and rock type. The system also collects magnetic data through a caesium magnetometer. The transmitter/receiver loop is suspended on a cable approximately 40m below the helicopter (Figure 1).
Figure 1 VTEM Max helicopter deployed electromagnetic survey arrangement.
Figure 2 Prospects and VTEM Survey areas.
Money Intrusion
The Money Intrusion, which has proven potential to host Ni-Cu-Co-PGE (platinum group elements), is part of the regional Mundine Well Dolerite Suite, a regionally extensive dolerite (strike length >80km). This extensive mafic intrusion, which is comprised of a variety of lithologies, including gabbro in the core, olivine dolerite on the chilled lower contact or keel and fine-grained dolerite on the outer edges. Mapping, aeromagnetics and multi-spectral imagery show that the Money Intrusion within the Ti-Tree Project covers a strike length greater than 16km, reaching widths >600m in the north of E09/23241.
