MONTREAL, QC / ACCESSWIRE / February 15, 2022 / Quebec Precious Metals Corporation ("QPM" or the "Company") (TSXV:QPM)(OTCQB:CJCFF)(FSE:YXEP) is pleased to report preliminary test results from six (6) representative samples from the La Pointe and La Pointe Extension deposits on the Company's 100% owned Sakami project in the Eeyou Istchee James Bay territory of Quebec.

蒙特利爾,QC/ACCESSWIRE/2022年2月15日/魁北克貴金屬公司(以下簡稱“QPM”或“公司”)(多倫多證券交易所股票代碼:QPM)(場外交易市場代碼:QPM)(多倫多證券交易所股票代碼:YXEP)高興地報告了對該公司在魁北克省Eeyou Istchee James Bay領地La Pointe和La Pointe延伸礦藏的六(6)個代表性礦樣的初步測試結果,該項目是該公司在魁北克省Eeyou Istchee James Bay地區100%擁有的Sakami項目。

Highlights of the test results

測試結果的亮點

  • Optimal gold recovery would require a conventional milling flowsheet with crushing, grinding, gold leaching and dissolved gold recovery.
  • Gold recoveries ranging from 91% to 99% were obtained from six (6) representative composite samples with cyanidation.
  • The grinding Bond work index ranges from 9.1 to 11.1 kWh/t, which is considered as medium strength values in the gold extraction industry.
  • The mineralogical composition confirms that no deleterious components to cyanidation processes are present in the tested material.
  • 最佳的金回收將需要一個傳統的球磨流程,包括粉碎、研磨、金浸出和溶解金回收。
  • 用氰化法從6個有代表性的複合樣品中獲得了91%~99%的金回收率。
  • 磨礦結合功指數在9.1~11.1kWh/t之間,被認為是黃金提煉行業的中等強度值。
  • 礦物學成分證實,測試材料中不存在對氰化過程有害的成分。

Normand Champigny, QPM's Chief Executive Officer, stated: "We are happy to receive the confirmation of the excellent gold recoveries and the lack of deleterious component. This enhances the economic potential of the Sakami Project with metallurgical results in line with operating gold mines. The results are an important step for the Company as the project progresses towards its maiden resource estimate. Additional test work is planned and will be integrated with the estimate."

QPM首席執行官諾曼德·錢皮尼(Normand Champigny)表示:“我們很高興收到關於黃金回收率極高且沒有有害成分的確認。這增強了阪上項目的經濟潛力,其冶金效果與運營的金礦一致。隨着該項目邁向其首次資源評估,這一結果對該公司來説是重要的一步。計劃進行額外的測試工作,並將其與估算相結合。"

The metallurgical testing program was performed at the Centre technologique des résidus industriels (CTRI), based in Rouyn-Noranda, under the supervision of Soutex inc. ("Soutex"). The program's objective was to deliver preliminary metallurgical data to support the preparation of a mineral resource estimate. The tests included quantitative mineralogical analysis, grindability tests (to determine grinding power requirements) and cyanidation tests at two (2) grinding levels with P80 of 75 and 40 µm.

冶金測試計劃在工業技術研究中心(CTRI),總部設在魯因-諾蘭達,由Soutex Inc.(“Soutex”)監管。該計劃的目標是提供初步冶金數據,以支持礦產資源評估的準備。這些測試包括定量礦物學分析、可磨性測試(以確定磨礦功率要求)和兩(2)個磨礦水平(P80分別為75和40µm)的氰化試驗。

A total of 187 core holes (53,861 m) have been drilled at the La Pointe and La Pointe Extension deposits. QPM is currently drilling to expand the La Pointe Extension deposit (see press release of November 2, 2021) in preparation for a mineral resource estimate. The La Pointe deposit has been defined over a strike length of 950 m and to a minimum depth of 700 m with an estimated true thickness of 35 m in the main portion of the deposit. The La Pointe Extension deposit has been defined over a strike length of 3,750 m and to a minimum depth of 400 m with an estimated true thickness of 39 m (see press release of June 9, 2021) in the central part of the deposit. The central part of the deposit shows an average true thickness of 39 m and up to 75 metres.

在La Pointe和La Pointe延伸礦牀共鑽了187個巖心孔(53,861米)。QPM目前正在鑽探,以擴大La Pointe延伸礦藏(T.N:行情).參見2021年11月2日的新聞稿),為礦產資源評估做準備。La Pointe礦牀的走向長度為950米,最小深度為700米,主要部分的真實厚度估計為35米。La Pointe延伸礦牀的走向長度為3750米,最小深度為400米,估計真實厚度為39米(參見2021年6月9日的新聞稿)位於礦牀的中心部分。礦牀中部的平均真實厚度為39米,最高可達75米。

Six (6) drill hole composite samples taken from the La Pointe and La Pointe Extension deposits were prepared. The samples assayed head grades ranging from 1.0 to 3.6 g/t Au. The samples are considered spatially representative of the deposits and the geological character of the mineralization.

從LaPointe和La Pointe伸展礦牀中提取了六(6)個鑽孔複合樣品。這些樣品的頭部品位從1.0到3.6g/t Au不等。這些樣品被認為在空間上代表了礦牀和礦化的地質特徵。

Mineralogical analysis

礦物學分析

A quantitative scan mineralogical analysis (QEMSCAN) has been conducted on each sample to measure their sulphide minerals content, with results ranging from 1.9 to 3.4%. The primary sulphides present are pyrite, pyrrhotite and arsenopyrite. The concentration levels of these samples are not significant enough to impact the cyanidation process. The other main constituents are quartz and feldspar.

對每個樣品進行了定量掃描礦物學分析(QEMSCAN),以測定其硫化物礦物含量,結果從1.9%到3.4%不等。原生硫化物有黃鐵礦、磁黃鐵礦和毒砂。這些樣品的濃度水平不足以影響氰化過程。其他主要成分為石英和長石。

Grindability tests

研磨性試驗

The grinding Bond work index was determined from the samples. The values vary from 9.1 to 11.1 kWh/t. These values are considered as medium, meaning that energy required for grinding will be in the medium range compared to other ores of similar type.

從樣品中測定了磨削結合功指數。這些值在9.1到11.1kWh/t之間變化。這些值被認為是中等的,這意味着與其他類似類型的礦石相比,磨礦所需的能量將處於中等範圍。

Cyanidation tests

氰化試驗

The cyanidation results show that recoveries significantly improve with a decrease in particle size P80 from 75 to 40 µm, with the recovery gain outweighing the expected additional grinding cost. The sodium cyanide consumption is low at about 0.4 kg/t after 36 hours, and the hydrated lime consumption is at 2 kg/t. The leaching time of 36 hours is sufficient to obtain maximum recovery. The gold dissolution rate for a P80 of 40 µm on two samples higher in arsenic was at 91% while varying from 95 and 99% for the other samples. Additional testing has been performed to evaluate the gold deportment, such as the diagnostic leach test. The results show no potential metallurgical improvement using flotation or gravimetric process in complement to cyanidation.

氰化結果表明,當P80粒度從75µm降至40µm時,回收率顯著提高,回收率的提高超過了預期的額外磨礦成本。36h後氰化鈉消耗較低,約為0.4 kg/t,消石灰消耗為2 kg/t,浸出時間為36h,可獲得最大回收率。在兩個砷含量較高的樣品上,40µm的P80對金的溶出率為91%,而對其他樣品的溶出率分別為95%和99%。已經進行了額外的測試來評估黃金行為,例如診斷浸出測試。結果表明,用浮選或重量法補充氰化沒有潛在的冶金改善作用。

The test results demonstrate that the best extraction option is a conventional milling flowsheet consisting of crushing, grinding and gold leaching. The sulphur content ranges from 1 to 2%, and the types of sulphide minerals are not harmful to the cyanidation process. There is a lack of deleterious components other than sulphides.

試驗結果表明,最佳的提取方案是由破碎、磨礦、浸金組成的常規球磨流程。硫含量在1%~2%之間,硫化礦物類型對氰化過程無害。除硫化物外,還缺少有害成分。

The Sakami Project

阪上計劃

The Project provides the Company with a controlling position over a 23-kilometre-long segment of a favourable geological contact and comprises 281 claims (142 km2).
