Augustus Minerals (ASX: AUG; “Augustus” or the “Company”) is pleased to provide the following summary of activities undertaken during the quarter ended 31 March 2024 (March Quarter).
Highlights
- Assay results received from last quarter's drilling at the Ti-Tree project identified mineralisation at several prospects.
- Strong results, consistent with the zones of a porphyry copper system were received from the first 22 holes drilled into the Minnie Springs Cu-Mo-Ag porphyry prospect, including intercepts of:
- MSRC012: 18m @ 0.37% Cu and 9.7 g/t Ag from 94m downhole, and;
- 16m @ 0.38% Cu and 19.4g/t Ag from 121m downhole
- MSRC022: 7m @ 0.19% Cu from 87m downhole
- MSRC011: 7m @ 0.12% Cu from 21m downhole
- MSRC012 mineralisation contained significant base metal and silver including:
- 5m @ 27.6 g/t Ag, 0.25% Pb and 0.15% Zn with 148 ppm Mo from 107m, and
- 14m @ 21.5 g/t Ag, 0.18% Pb and 0.1% Zn with 274ppm Mo from 122m
- Copper Ridge CRRC008 returned:
- 4m @ 0.91% Cu from 13m
- Including 2m @ 1.67% Cu
- A 3,400m RC drill program has commenced at Minnie Springs, with deeper diamond drilling planned for June.
- Extensive soil sampling program commenced, representing the first systematic exploration over large parts of the mineralised Ti-Tree and adjacent Minga Bar Shears
- Soil program to target both base metal-gold and lithium prospective Leake Spring Metamorphics as well as extensions to the Minnie Springs porphyry style copper- molybdenum trend.
- Cash position of $4.55m as of 31 March
During the period Augustus received the drill results from the Ti-Tree project’s maiden reverse circulation (RC) drilling program completed last quarter. The program was designed primarily to test six advanced targets where existing soil and/or rock chip anomalies had been generated.
Augustus has continued to advance its mineral exploration ground efforts within the Ti-Tree Project with a regional soil sampling program commencing in March and a second RC drilling program commencing in early April at the Minnie Springs Cu-Mo-Ag porphyry prospect.
Drilling Activities
The Ti-Tree project covers some 3,600km2 and overlies 85kms of strike of the Ti-Tree Shear which is known to host a significant number of mineral occurrences in the region. The project area also contains >20kms of strike of the Money Intrusion, where Dreadnought Resources (ASX:DRE) has recently discovered significant Ni-Cu-PGE mineralisation1 .
Assay results from late last quarter’s drilling which comprised 78 holes totalling 9,086m of Reverse Circulation (RC) drilling were received in the March quarter2.
The primary focus of this drill program was to target significant mineralised zones defined by surface exploration completed across the 6 prospect areas of Minnie Springs, Coo Creek, Nick’s Bore, Copper Ridge, Crawford Bore and Crawford South (Figure 1).

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).
