Augustus Minerals (ASX: AUG; Augustus or the Company) is pleased to advise that the EIS supported diamond drilling (DD) drill program has commenced at the Ti-Tree Project, ~200kms east of Carnarvon in Western Australia (Figure 1).
- Diamond Drilling has commenced to target a large copper-molybdenum porphyry system at Minnie Springs.
- The deeper diamond drilling is designed to target beneath a 3km long by 1km wide copper molybdenum soil anomaly.
- Previous drilling at Minnie Springs intersected mineralisation, geology and an alteration halo consistent with the zoning of a large porphyry copper / molybdenum system.
- The drilling is supported by a co-funded drilling grant of up to $110,000 for 700m deep diamond drill holes under the WA Government’s Exploration Incentive Scheme (EIS) for the Minnie Springs prospect.
Andrew Ford, GM Exploration
“The commencement of the diamond drilling marks an exciting time for Augustus, with the first hole testing below the existing molybdenum mineralised zone and targeting a high- grade copper core of a porphyry system”
The diamond program scheduled for completion mid-November.
Minnie Springs
Minnie Springs hosts porphyry related Copper - Mo mineralisation that was previously drilled by Equatorial Mining and Catalyst Metals. A molybdenum Exploration Target has previously been defined by SRK Consulting for the historic drilling area as outlined below (Table 1)1.
Alteration mapping suggests a potential tilting of the Minnie Springs system to the northeast, with untested potential for higher grade Copper - Mo mineralisation below existing drilling within the potassic altered zone (Figure 1).
Table 1. Exploration target size estimate for Minnie Springs Molybdenum depositNote: Based on ~300 ppm Mo cut-off at 100% recovery.
Clarifying Statement: The potential quantity and grade of the exploration target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resources, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

The program is supported by the WA Government’s Exploration Incentive Scheme (EIS) drilling grant of up to $110,000 for two 700m deep diamond drill holes at the Minnie Springs prospect.
The drilling is designed to provide a 550m deep, geological/geochemical/structural cross- section through the large 3km long by 1km wide copper molybdenum porphyry system.
Previous drilling at Minnie Springs intersected mineralisation, geology and alteration halo consistent with the zoning of a porphyry copper / moly system.

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).
