The Property, consisting of 988 claims (50,843 hectares), is also host to over 50 high-grade gold occurrences discovered by the Company since 2017. The Property is located proximal to the La Grande-Opinaca subprovince boundary. The majority of the lithium and gold deposits in
Additionally, the field team has observed coarse-grained tantalite crystals in nearby pegmatites and outlined a >15 km2 corridor rated as high potential for additional discoveries based on in-field X-Ray Fluorescence ('XRF') geoanalyses .
Highlights
Grab samples up to 2.61 and 4.56% Li2O in outcrops at Ameliane showing; Possible stacking of shallow-dipping and sub-parallel spodumene-bearing pegmatite dykes identified laterally over 300 metres at Ameliane; Grab samples with high-grade tantalum up to 21,000 ppm Ta (2.56% Ta2O5) and >25,000 ppm Ta (>3.05% Ta2O5); Prospective zone (>15 km2) for additional discoveries of lithium based on the chemical composition of muscovite in pegmatites.

Ameliane Showing Area
The discovery area, known as the Ameliane showing, consists of several spodumene occurrences in pegmatite outcrops and boulders. The actual news release discloses the best lithium grades obtained from 145 rock samples sent to ALS (
Pegmatites in the area contain muscovite and biotite with accessory minerals such as tourmaline, garnet, beryl, spodumene, tantalite and apatite. Spodumene, hosting the lithium mineralization, consists of light grey to greenish elongated crystals ranging from centimetre size up to 1.40 metres in length. The spodumene content reaches up to 50% locally at Ameliane.
Beryl crystals, up to 70 centimetres in length, are common in pegmatites at Serpent-Radisson. Their content reaches up to 10% locally and more than 30 grab samples exceed 360 ppm Be which is the threshold value for a beryllium showing. Cesium is strongly correlated with beryllium values as both chemical elements are hosted in beryl. Beryl-bearing pegmatites commonly have elevated cesium values in the range of a few hundreds of ppm. One sample of pegmatite without beryl returned >2.5% cesium suggesting the presence of pollucite. Tantalite, a tantalum-rich oxide, was also observed in a few pegmatite occurrences. Two grab samples with coarse-grained tantalite crystals returned 2.1% tantalum (2.56% Ta2O5) and >2.5% tantalum (>3.05% Ta2O5). The pegmatite field at Serpent-Radisson has the potential to host lithium, tantalum, cesium and beryllium orebodies.
This zone, defined by low potassium/rubidium ('K/Rb') ratios on muscovite as measured with a hand-held XRF instrument, stretches into a NNE-SSW direction and likely extends towards the Arwen lithium discovery on
Future Exploration Program on Serpent-Radisson
Harfang is contemplating a drill program in 2024 in order to test the down-dip and lateral extent of the various dykes and the presence of potential stacked and unexposed dykes as part of its exploration strategy for critical and strategic minerals. The Mista Cu-Au-Ag showing ('Mista') located 1.5 kilometres to the southwest would also be drilled. Channel sampling across the Mista mineralized horizon, which has been traced laterally over 350 metres, previously returned up to 1.00% Cu, 0.21 g/t Au and 7.9 g/t Ag over 12.9 metres . The mineralized horizon is coincident with a 700 metre-long induced polarization chargeability anomaly with the strongest chargeability segments hidden under the overburden cover. Chargeability axes are commonly caused by sulphide occurrences including chalcopyrite, pyrrhotite and pyrite which are present at Mista.
Sampling Protocols and Quality Control
Each rock sample was placed in a plastic bag with its own identification tag directly on the field. These samples were then placed in large bags and sent to ALS (
