Augustus Minerals Limited (ASX: AUG; Augustus or the Company) is pleased to announce the commencement of the previously announced airborne Versatile Time Domain Electromagnetic (VTEM) Max survey over three areas within the 3,600km2 Ti-Tree Project in the Gascoyne Region. The survey should be finished this week with final data expected within four to six weeks.
- The VTEM Max survey over Cu-Ni-PGE, Broken Hill Style and Uranium targets has commenced.
- The survey is covering:
- The Money Intrusion, prospective for Cu-Ni-PGE mineralisation.
- Copper Ridge and Nick’s Bore over anomalous Copper Drilling results.
- The Coo Creek prospect where drilling by Augustus in 2023 identified strongly anomalous Zn-Pb-Ag mineralisation of possible Broken Hill Style massive sulphide.
- The Munaballya Well 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.
VTEM
UTS Geophysics is conducting the 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.

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). 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 (Figure 2).
The VTEM Max system will look to identify conductive anomalies which may reflect concentrations of massive to semi-massive sulphide along the thicker parts of the Money Intrusion within AUG tenure.

High grade Massive Sulphide Intercepts Confirmed at Oval
HIGHLIGHTS:
- OVD027 confirms the continution of high grade massive sulphide from OVD0211 with an intercept of 6.1 metres of 4.16% Cu, 3.51% Ni, 0.G3g/t E3, and 0.13% Co from G8.2 metres encountered between broader high grade zones of:
- A dense disseminated intercept - 26.2 metres of 0.44% Cu, 0.52% Ni, 0.12g/t E3, and 0.03% Co from 72.0 metres and
- A net textured intercept - 15.3 metres of 1.15% Cu, 0.79% Ni, 0.35g/t E3, and 0.04% Co from 104.3 metres;
- A high grade broad intersection is confirmed at the central part of the Oval area by OVD026. It includes a massive sulphide intercept in hole OVD026 of 1.8 metres of 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co from 105.0 metres within broader mineralisation of:
- 19.8 metres of 1.23% Cu, 0.98% Ni, 0.36g/t E3, and 0.05% Co from 91.2 metres.
OVD026 is located 100 metres northwest of the previously announced 8.8 metres of massive sulphide identified in drillhole OVD021.
On completion of the Phase 2 exploration work and receipt of all assays, Managing Director Gan-Ochir Zunduisuren, commented:“The 2024 Phase 1 and 2 drilling and exploration programs have confirmed the broad presence of high-grade mineralisation in the Oval gabbroic intrusion. The grades intercepted in some of the drillholes are exceptional and may be indicative of broader potential over a larger area, given Oval is a greenfields discovery.
The 2025 exploration program will focus on obtaining information on the size/metal content potential of the Oval Cu-Ni-PGE mineral system as well as targeting the possible deeper magmatic sources at Oval. Broader exploration is also planned at potential extensions of Oval and nearby look-a-like prospects. We look forward to updating shareholders on progress, with drilling expected to commence in around 8 weeks”.
Summary of Phase 2 exploration drilling at Oval Cu-Ni-PGE project
The Company’s recent drilling work has predominantly focused on finding high-grade mineralisation in the olivine-amphibole gabbro at the Oval project. The multiple intercepts of massive sulphide mineralisation with different ratios of metal contents throughout the Oval gabbroic intrusion is highly encouraging for the presence of one or more deeper sources of high grade mineralisation in the opinion of ABM.

Drillhole OVD02c
Drillhole OVD026 was designed to test the Down-Hole Electromagnetic (DHEM) conductor plate identified as OVD007_L2_B (reinterpretation of OVD007_L2_A2 by Southern Geoscience Consultants), which exhibits a conductance of 1,000 siemens. The drilling intersected a total of 1G.8 metres of mineralisation with 1.23% Cu, 0.G8% Ni, 0.36g/t E3, and 0.05% Co from G1.2 metres including;
- 4.8 metres of @ 0.45% Cu, 0.43% of Ni, 0.14g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 91.2 metres,
- 6.6 metres of @ 1.56% Cu, 0.G0% Ni, 0.50g/t E3, and 0.04% Co of net textured mineralisation from G6.0 metres,
- 2.4 metres of @ 1.52% Cu, 1.3G% Ni, 0.43g/t E3, and 0.07% Co of semi massive sulphide mineralisation from 102.6 metres,
- 1.8 metres of @ 3.21% Cu, 3.32% Ni, 0.6Gg/t E3, and 0.14% Co of massive sulphide mineralisation from 105.0 metres, and
- 4.2 metres of @ 0.57% Cu, 0.45% of Ni, 0.21g/t E3, and 0.02% Co of dense disseminated mineralised gabbro from 106.9 metres (Table 1 provides a detailed breakdown of mineralisation intervals).
OVD026 is located in the Oval area, which is approximately 100 metres northwest of the previous intersection identified in drillhole OVD0213. This intercept may represent an extension of the known massive sulphide mineralisation in the Oval area and highlights the potential for further expansion of massive sulphide zones within the broader prospect area (Figures 1 and 3).
