Oceana Lithium Limited (ASX:OCN)(Oceana or the Company) is pleased to advise that field exploration work is now underway at the Monaro Lithium Project in James Bay Québec.
Key Points
- Field exploration commences at Monaro Lithium Project following lifting of wildfire access restrictions.
- Québec based contractor Explo-Logik has mobilised an experienced exploration team with helicopter support to target high-priority areas.
- In preparation for its inaugural field season Oceana has identified various high priority targets within the Monaro project area. These targets will be investigated on the ground during the current field campaign with a focus on identifying spodumene bearing pegmatites.
- These targets include the two reported Québec Government SIGÉOM pegmatites; some 114 large linear structures with surface signs of pale outcrop, some up to 1.25 km in length identified from high resolution satellite imagery, as well as 26 spectral targets selected from Sentinel 2 remote sensing data.
- Monaro covers 104 km2 in the western portion of the Archean Duhesme Lake metavolcano-sedimentary greenstone belt, that can be traced about 40 km along strike and 4-5 km across and is known to host lithium-caesium-tantalum (LCT) mineralisation.
- The project is located 10 km north-west of the Adina Lithium Project, where owner Winsome Resources (ASX: WR1) has reported significant lithium mineralised pegmatite intercepts1.
Experienced Québec based contractor Explo-Logik has mobilised at the Mirage Outfitter camp to conduct the inaugural helicopter-supported field program over the Monaro project area. The program consists of mapping, prospecting, rock, till and soil sampling with onsite XRF analyses for key LCT pegmatite pathfinder elements (Cs, Be, Nb, Sn, P, Rb, and Ta).
Oceana has identified numerous geological features, magnetic structures and visual supported by four support field technicians working on a rotational basis. The exploration team plans to sample over 60 locations, with samples to be sent to ALS in Val-d’Or, Québec for analysis with field activity expected to continue until mid to late September.

Sentinel 2 visible/near infrared (VNIR) and shortwave infrared (SWIR) and Aster Multispectral and Synthetic Aperture Radar (SAR) data has been acquired for the Monaro project area and analysed. Analysis of the emission spectra, with a focus on dihydrogen or helium which have strong emission lines in the VNIR, has generated targets, which could be indicative of the mineral zeolite, common in pegmatites, and cookeite, a weathering product of the lithium mineral lepidolite. Twenty-six (26) spectral targets (gas and resistivity), excluding 4 targets previously reported which actually lie on the periphery of the tenements (Oceana’s ASX announcement 5 July 2023), have been generated from these data sets (see Figure 2). This method has been applied with great success in lithium exploration in Western Australia.

The Company has also purchased high resolution PNEO 30cm 6-Band satellite imagery for the tenement area, and a LiDAR survey contractor has been appointed to gather additional high resolution topography data and imagery to further assist in pegmatite identification and accurate delineation.

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).
