MONTREAL, Aug. 22, 2024 (GLOBE NEWSWIRE) -- Harfang Exploration Inc. ("Harfang" or the "Company") (TSX.V: HAR) is pleased to announce another lithium discovery at its wholly-owned Serpent-Radisson Property (the "Property") in Eeyou Istchee James Bay, Québec (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
- Results Suggest Potential for Stacked Pegmatite Dyke System: The Milou discovery suggests a possible series of southeast shallow-dipping and sub-parallel spodumene-bearing pegmatite dykes (a stacked system). Testing this hypothesis will require investigating the potential 400 metre to 500-metre-wide corridor (true thickness), increasing the likelihood of additional lithium discoveries on the property.
- Milou Delivers High-Grade Lithium Samples up to 2.97% Li2O: Grab samples from the Milou discovery that were collected from numerous exposed pegmatite dykes returned assay results highlighted by 2.97% Li2O, 2.17% Li2O and 2.03% Li2O.
- Early Results from Summer 2024 Exploration Program are Positive: The Company has received and processed the first batch of assay results from the summer 2024 exploration program in Eeyou Istchee James Bay program, which has confirmed the discovery of new lithium-bearing pegmatites.
"This is a significant development for our exploration efforts in the James Bay region," commented Mr. Vincent Dubé-Bourgeois, Interim President and CEO. "The Milou discovery expands the mineralized system further north and provides additional insight into the potential stacking of spodumene-bearing pegmatite dykes. Our team is highly encouraged by these results, and we look forward to advancing our understanding of the region's lithium potential."
Potential for Hidden Lithium Mineralization in the Stacking Zone
The Milou discovery, located approximately 1.8 km to the NE of the Améliane showing, could represent the northern extension of a large lithium-pegmatite system. Field observations at Milou include a similar strike and dip to Améliane, which reinforce the evidence of the possible stacking of shallow-dipping and sub-parallel spodumene-bearing pegmatite dykes, as previously suggested by Harfang (see news release dated December 6, 2023).
The two pegmatite trend projections are approximately 1,000 metres apart on surface, indicating the presence of a zone measuring 400 metres to 500 metres wide (true thickness) that may host multiple spodumene-bearing dykes (Figures 4 and 5). The pegmatites observed and tested are highly fractionated and beryllium-rich – a favorable magmatic setting for mineralization.
This potential stacking zone offers encouraging exploration opportunities for hidden lithium mineralization, comparable in width to the 500-metre-wide corridor at Patriot Battery Metals Inc.'s CV5 Shaakichiuwaanaan (formerly Corvette) deposit.
High-Grade Lithium at 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 over 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 in the early phase of the summer program. Note that grab samples are selective by 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 alongside the spodumene. The pegmatite dykes are exposed irregularly over a cumulative length of approximately 100 metres, trending in an ENE direction and dipping approximately 25° to 30° to the SE (Figures 4 and 5). The dykes are estimated to be approximately 5 metres thick. Field analyses performed on muscovite crystals using a handheld X-Ray Fluorescence (XRF) instrument indicates similarly low (<15) potassium/rubidium ratios to Améliane, typically associated with fertile pegmatites.
Additional Beryllium, Cesium and Tantalum Discoveries
Four (4) beryllium showings have been discovered in the southeast pegmatite field at Serpent-Radisson, 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 were as high as 1,404 ppm Ta2O5 (1,150 ppm Ta).
Successful Early Phase of the 2024 Exploration Program
Initial Summer 2024 prospecting at the Serpent-Radisson Property has resulted in discoveries of critical and strategic elements, including lithium and beryllium in pegmatite dykes. This news 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, Québec), a certified commercial laboratory, to be analyzed for lithium and a suite of other chemical elements. These samples were prepared using the RX1 method and analyzed by ICP-OES & ICP-MS (UT7) for 55 elements, including Li (15ppm - 5%) following a sodium (total) peroxide fusion. Overrange assays for beryllium were reanalyzed using the 8-Peroxide ICP-OES method. A strict QA/QC procedure was implemented, with one certified reference material (CRM) and one blank sample inserted into the sample stream for every batch of 50 samples.

蒙特利爾,2024年8月22日(GLOBE NEWSWIRE) – 長益勘探公司(Harfang)很高興宣佈其位於魁北克Eeyou Istchee James Bay的全資Serpent-Radisson地產(簡稱「地產」)又發現了一處鋰礦牀(圖1)。在伊晨伊斯切·詹姆斯灣地區的Améliane鋰礦點東北約1.8公里處發現了名爲Milou的透閃長石脈中的透閃石結晶(圖2和3)。
亮點
- 結果顯示疊層透閃長石脈系統潛力:Milou的發現表明可能存在一系列向東南淺傾斜、互相平行的含透閃石的透閃長石脈(疊層系統)。測試這個假設將需要調查潛在的400米到500米寬的走廊(實際厚度),增加了在地產上發現額外鋰礦的可能性。
- Milou提供高品位鋰礦樣品,最高達2.97% Li2O:Milou發現的摘取樣品來自多處露頭透閃長石脈,化驗結果顯示2.97% Li2O、2.17% Li2O和2.03% Li2O。
- 2024年夏季勘探項目初期結果積極:公司已經收到並處理了在Eeyou Istchee James Bay進行的2024年夏季勘探項目的首批化驗結果,這些結果已經證實發現了新的含鋰長石脈。
"對於我們在詹姆斯灣地區的勘探工作來說,這是一個重大進展,"臨時總裁兼首席執行官文森特·迪比-布爾瓦(Vincent Dubé-Bourgeois)先生評論道。"Milou的發現將礦體系統進一步向北擴展,並提供了關於透閃石脈疊置潛力的額外見解。我們的團隊對這些結果充滿信心,並期待着進一步了解該地區的鋰礦潛力。"
潛在的鋰礦物化富集可能性在堆積帶中
米盧發現位於Améliane表露以東北約1.8公里處,可能代表一個大型鋰重晶巖體系的北部延伸。米盧的野外觀察包括與Améliane相似的走向和傾角,進一步證實了可能存在淺傾斜和互平行的含鋰角閃岩脈的堆積跡象,正如Harfang先前所暗示的(請參閱2023年12月6日的新聞稿)。
兩個重晶巖趨勢預測在地表上相距約1,000米,表明存在一條寬度爲400米至500米(實際厚度)的區域,可能容納多條含鋰角閃岩脈(圖4和5)。觀察和測試的重晶巖具有很高的分餾作用和富鋰 - 這是有利的岩漿成礦背景。
這個潛在的堆積帶爲隱藏的鋰礦化提供了鼓舞人心的勘探機會,與愛國者電池金屬公司CV5 Shaakichiuwaanaan(前稱Corvette)礦牀的500米寬走廊相當。

高度分級長石結晶濃度在地層板塊中的濃縮
長石晶體長度從2.5到25厘米不等,濃度高達30%(圖6)。 小綠柱石晶體也與長石共存。 礦脈岩石斷層不規則地分佈在總長約100米的區域內,趨勢爲ENE方向,傾斜角約25°至30°向東南(圖4和5)。 估計礦脈岩石斷層厚度約爲5米。 對白雲母晶體進行的野外分析表明,使用手持式X射線熒光(XRF)儀器表示鉀-銣比通常很低(<15),與富含礦巖相似。
額外的鈹、銫和鉭的發現
在蛇形-拉迪森東南部的板塊區域發現了四(4)個綠柱石礦脈,其品位高達1.27% Be(圖3)。 銫值在位於離白雲母礦脈展示區大約200米西的一個礦脈中高達597 ppm。 更南部,鉭的結果高達1,404 ppm Ta2O5(1,150 ppm Ta)。
2024年勘探計劃初期階段取得成功
2024年夏季在Serpent-Radisson地塊的初步勘探已經發現了包括鋰和鈹在內的關鍵和戰略元素,這則新聞發佈突出了夏季計劃前15天收集的108個岩石樣本中獲得的最高鋰品位,這些樣本由Val-d'Or的ActLabs分析所得。
取樣協議和質量控制
野外收集的每個岩石樣本都被鑑定並送往位於魁北克Val-d'Or的ActLabs(一家認證的商業實驗室)進行鋰和一系列其他化學元素的分析。這些樣本採用了RX1方法制備,並通過ICP-OES和ICP-MS(UT7)對55種元素進行分析,包括Li(15ppm-5%),採用了鈉(總)過氧化物熔融法。超量程的鈹單獨使用8-過氧化物ICP-OES方法進行再分析。嚴格的QA/QC程序得到實施,每批50個樣本中插入一個經過認證的參比材料(CRM)和一個空白樣本。
