Harfang Announces Lithium Discovery in Serpent-Radisson, Quebec By Investing.com

MONTREAL, Aug. 22, 2024 (GLOBE NEWSWIRE) — Harfang Exploration Inc. (Snowy Owl or the Business) (TSX.V: HAR) is pleased to announce another lithium discovery on its wholly-owned Serpent-Radisson property (the Property) in Eeyou Istchee Baie-James, Quebec (Figure 1). The discovery of spodumene crystals in pegmatite dykes, named Milou, is located approximately 1.8 kilometres NE of the Améliane lithium showing (Figures 2 and 3).

Highlights

• The results suggest potential for a stacked pegmatite dam system: The Milou discovery suggests a possible series of subparallel, gently dipping southeast-trending spodumene pegmatite dykes (a superimposed system). Testing this hypothesis will require investigation of the potential 400-500 metre wide (true thickness) corridor, which will increase the likelihood of additional lithium discoveries on the property.
• Milou delivers high quality lithium samples up to 2.97% Li2O: Grab samples from the Milou discovery, taken from numerous exposed pegmatite dykes, returned assay results of 2.97% Li2O, 2.17% Li2O and 2.03% Li2O.
• The first results of the summer 2024 exploration program are positive: The Company received and processed the first batch of assay results from the summer 2024 exploration program at Eeyou Istchee James Bay, which confirmed the discovery of new lithium-bearing pegmatites.

“This is an important development for our exploration efforts in the James Bay region,” commented Mr. Vincent Dubé-Bourgeois, Acting President and CEO. “The Milou discovery extends the mineralized system further north and provides additional information on the potential stacking of spodumene pegmatite dykes. Our team is very encouraged by these results and we look forward to advancing our understanding of the lithium potential of the region.”

Potential for hidden lithium mineralization in the stacking zone

The Milou discovery, located approximately 1.8 km NE of the Améliane showing, may represent the northern extension of a large lithium pegmatite system. Field observations at Milou include a similar strike and dip to Améliane, reinforcing the evidence for the possible stacking of gently dipping, subparallel spodumene pegmatite dykes, as previously suggested by Harfang (see press release dated December 6, 2023).

The two pegmatite projections are approximately 1,000 meters apart at surface, indicating the presence of a zone measuring 400 to 500 meters wide (true thickness) that could host several spodumene-bearing dykes (Figures 4 and 5). The observed and tested pegmatites are highly fractionated and beryllium-rich, providing a favorable magmatic context for mineralization.

This potential stacking zone offers encouraging exploration opportunities for hidden lithium mineralization, comparable in width to the 500 metre wide corridor of Patriot Battery Metals Inc.’s CV5 Shaakichiuwaanaan (formerly Corvette) deposit.

High quality lithium in Milou

Grab samples from the Milou lithium discovery returned grades up to 2.97% Li2O (13,800 ppm Li), including four (4) samples exceeding 2.00% Li2O and three (3) additional samples exceeding 1.30% Li2O. Table 1 shows selected assay results from the Milou discovery above the 0.25% Li2O threshold for lithium showings. These samples were collected early in the summer program. Please note that grab samples are selective in nature and may not represent average grades.

Concentration of spodumene crystals in highly fractionated pegmatites

Spodumene crystals range from 2.5 to 25 centimetres in length, with concentrations up to 30% (Figure 6). Small beryl crystals are also present along the spodumene. Pegmatite dykes are exposed irregularly over a cumulative length of about 100 metres, oriented ENE and dipping about 25° to 30° to the SE (Figures 4 and 5). The dykes are estimated to be about 5 metres thick. Field analyses of muscovite crystals using a portable X-ray fluorescence (XRF) instrument indicate similarly low values ​​(

Additional discoveries of beryllium, cesium and tantalum

Four (4) beryllium showings were discovered in the southeast Serpent-Radisson pegmatite field, with grades up to 1.27% Be (Figure 3). Cesium values ​​reached up to 597 ppm in a pegmatite located approximately 200 metres west of the Améliane showing. Further south, tantalum results reached 1,404 ppm Ta2O5 (1,150 ppm Ta).

Success of the first phase of the 2024 exploration program

Initial prospecting work in the summer of 2024 on the Serpent-Radisson property has led to the discovery of critical and strategic elements, including lithium and beryllium in pegmatite dykes. This press release highlights the highest lithium grades obtained from 108 rock samples collected during the first fifteen days of the summer program and analyzed by ActLabs in Val-d’Or.

Sampling protocols and quality control

Each rock sample collected in the field was identified and sent to ActLabs (Val-d’Or, Quebec), a certified commercial laboratory, for analysis for lithium and a range of other chemical elements. These samples were prepared using the RX1 method and analyzed by ICP-OES and ICP-MS (UT7) for 55 elements, including Li (15 ppm – 5%) after sodium peroxide fusion (total). Beryllium overrange assays were reanalyzed using the 8-peroxide ICP-OES method. A strict quality assurance/quality control procedure was implemented, with a certified reference material (CRM) and a blank sample inserted into the sample stream for every batch of 50 samples.
