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.

EIS Grant for Minnie Springs Copper Porphyry Drilling
- Augustus Minerals has been granted a co-funded drilling grant of up to $110,000 for 2 x 700m deep diamond drill holes under the WA Government’s Exploration Incentive Scheme (EIS) for the Minnie Springs prospect.
- The deeper diamond drill program is designed to test and to provide a 550m deep, 1km wide geological/geochemical/structural cross-section through the large 3km long by 1km wide copper moly porphyry system, linking the Mo mineralised leucogranite to the extensive Cu in soil anomaly to the northeast.
- Previous RC drilling at Minnie Springs intersected mineralisation, geology and alteration halo consistent with the zoning of a large porphyry copper / moly system.
Andrew Ford, GM Exploration
“The Company is pleased to receive an EIS grant to complete deeper drilling at the Minnie Springs Copper Molybdenum Project. The resultant data will enable mapping of the lithology and alteration to a depth of 550m and potentially intersect, or provide vectors to, higher grade Mo-Cu mineralisation using a Mo-Cu porphyry geological model”.
Minnie Springs
Minnie Springs hosts porphyry related copper molybdenum mineralisation previously drilled and defined by Catalyst Metals. A molybdenum Exploration target has been defined for the historicdrillingareacomprisedofbetween12-84Mtasoutlinedbelow (Table 1 and Figure 1, 2.)1.
Table 1. Exploration target size estimate for Minnie Springs Molybdenum depositNote: Based on ~300 ppm cut-off at 100% recovery.
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 planned diamond drilling will complement the recently completed 3,200m RC drilling program that infilled around hole 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 downhole2) and tested the northern half of the 2km long copper-in soil anomaly. Assays from this program are expected to become available over the next month.
The limited exploration in the region, highlighted by 95% of the Ti-Tree project having no previous exploration, demonstrates the prospectivity of this underexplored mineral province.

Quarterly Activity Report 31 March 2024
Figure 1. Fiery Creek Copper Prospect/Yataga Granodiorite summarizing rock (brown diamonds) and termite mound sample results (black crosses)
Continuing with its primary exploration focus on the Georgetown project in the latter half of 2023, EMU received assay results during the quarter from its second, in field reconnaissance work. The geochemical sampling programme covered the Fiery Creek high grade copper vein swarm and the Snake Creek prospects with significant element results returned from the Fiery Creek Copper (elevated Cu-Au-Ag-Bi-In-Pb-Sb-Te) and Snake Creek (elevated Pb-Ag-Au-Sb).
Whilst the survey was cut short due to inclement weather, EMU was encouraged by the significant success reflected in the assays results. The results from mineralogical studies confirmed EMU’s interpretation of an indicative, scale Copper-Porphyry system at the Fiery Creek prospect and was a highlight of the survey with new information building on the scale and potential of the prospect1.
Assay results returned included:
- Fiery Creek rock assay results up to 23.5% Cu, 0.27ppm Au, 460ppm Ag, 1.9% Bi, 89ppm In, 2.7% Pb, 667ppm Sb, 1470ppm Zn2.
- evidence of strong potential for the presence of critical and strategic minerals (Cu, Bi, In), with precious and base metals.
- evidence of alteration mineralogy, mineralisation geochemistry and areal extent of the Fiery Creek quartz-Cu-Bi vein swarm strongly suggesting a previously unrecognised subjacent porphyry Cu-Mo system.
- Yataga Granitoid Complex termite mound and coincident rock chip sampling returned several anomalous polymetallic zones for follow up.
- Snake Creek Prospect assays returned 0.20ppm Au, 390ppm Ag, 22.4% Pb, 464ppm Sb1.
Significant results were returned from the Fiery Creek Copper prospect with elevated Cu-Au- Ag-Bi-In-Pb-Sb-Te and from the Snake Creek prospect with elevated Pb-Ag-Au-Sb.
The elevated pathfinder element results and a macro-petrology assessment3 of rock samples completed by Mr Nigel Maund, Consulting Economic Geologist, from the previously unexplored Fiery Creek Prospect, point to the discovery of a porphyry copper system.
The sampling program assessed a number of high-priority prospects within the Georgetown Project tenements utilising termite mound and outcrop rock chip geochemistry. A total of 46 rock chip and 489 termite mound samples were collected across eight prospects.
