Highlights
- Discovery of several pegmatite dykes with up to 50% spodumene crystals mapped at several localities spread over at least 1 kilometre;
- Boulder field containing only angular spodumene-bearing pegmatite floats of cubic metre dimensions down-ice of the discovery outcrop;
- The discovery occurred at the early stages of the field program on the Property and surface work is ongoing until the end of the prospecting season.

From LCT Pegmatites to the Spodumene Discovery
The current program confirms, for the first time, the presence of major lithium mineralization in pegmatite outcrops and boulders. The lithium mineralization consists of light grey to greenish elongated spodumene crystals ranging from centimetre size up to 1.40 metres in length. The spodumene content is highly variable and reaches up to 50% locally (Figures 3 to 6). Mapping to date has confirmed that several pegmatite dykes contain spodumene at different localities spread over at least 1 kilometre. Harfang has accelerated its efforts to test the extensions of this discovery before the prospecting season ends. Pegmatites in the area contain muscovite with accessory minerals such as tourmaline, garnet, apatite and beryl. The beryl content reaches up to 10% locally in the surrounding pegmatites.
The spodumene-bearing boulder field measures about 10-30 metres in size and is located 30 metres southwest of the discovery outcrop. The floats in the boulder field are angular, have a cubic metre size and are exclusively composed of spodumene-bearing pegmatite (Figure 6). Harfang believes that the boulders have not been transported by the glacier and hence could indicate the presence of Lithium-Cesium-Tantalum pegmatites (“LCT pegmatites”) in the underlying bedrock.
Harfang has just started its field campaign on Serpent-Radisson as part of a follow-up on a reconnaissance campaign done in the eastern part of the Property during summer 2022 to evaluate the lithium potential of pegmatites. Grab samples collected during that campaign showed that these intrusive rocks, which contain highly anomalous beryllium (up to 25,000 ppm), lithium (up to 1,420 ppm), cesium (up to 998 ppm), tantalum (up to 173 ppm), niobium (up to 278 ppm) and rubidium (up to 1,095 ppm), fall in the category known as LCT Pegmatites (see news release dated
The field crew is still collecting rock samples on the Property. Analytical results will be disclosed as soon as available.
Polymetallic Mineralization in Eastern Serpent-Radisson
Over the years, diverse styles of mineralization have been highlighted by Harfang in the eastern part of the Property (Figure 2). Mista is the most significant showing in the area with up to 0.99% Cu, 0.20 g/t Au and 7.7 g/t Ag over 11.7 metres in width from channel sampling. This showing consists of a quartz-rich arenite/wacke horizon injected by quartz veins mapped at the surface over 350 metres in length and is coincident with an induced polarization chargeability anomaly obtained from an induced polarization survey. That survey suggests that the mineralized horizon could be as long as 700 metres with its strongest chargeability zone, probably related to a higher content in sulphides, hidden under the overburden cover.
Moreover, the area hosts many high-grade gold occurrences discovered by Harfang such as Lawr (189 g/t Au, 200 g/t Ag and 1.7% Pb [grab], and 9.79 g/t Au over 1.25 m [channel]), Anaconda Ouest (117 g/t Au), and Couleuvre (38.40 g/t Au) (see news releases dated
The recent lithium discovery coupled with the already known gold, copper and silver occurrences considerably enhances the mineral potential in the eastern part of Serpent-Radisson. This portion of the Property has received limited field work as the previous focus of the Company was oriented toward the western half where most of the exploration work has been conducted since 2020 based on the discovery of gold-rich till and soil and abundant associated gold occurrences in bedrock.
