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.

蒙特利尔,QC/ACCESSWIRE/2022年2月15日/魁北克贵金属公司(以下简称“QPM”或“公司”)(多伦多证券交易所股票代码:QPM)(场外交易市场代码:QPM)(多伦多证券交易所股票代码:YXEP)高兴地报告了对该公司在魁北克省Eeyou Istchee James Bay领地La Pointe和La Pointe延伸矿藏的六(6)个代表性矿样的初步测试结果,该项目是该公司在魁北克省Eeyou Istchee James Bay地区100%拥有的Sakami项目。

Highlights of the test results

测试结果的亮点

  • 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.
  • 最佳的金回收将需要一个传统的球磨流程,包括粉碎、研磨、金浸出和溶解金回收。
  • 用氰化法从6个有代表性的复合样品中获得了91%~99%的金回收率。
  • 磨矿结合功指数在9.1~11.1kWh/t之间,被认为是黄金提炼行业的中等强度值。
  • 矿物学成分证实,测试材料中不存在对氰化过程有害的成分。

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首席执行官诺曼德·钱皮尼(Normand Champigny)表示:“我们很高兴收到关于黄金回收率极高且没有有害成分的确认。这增强了坂上项目的经济潜力,其冶金效果与运营的金矿一致。随着该项目迈向其首次资源评估,这一结果对该公司来说是重要的一步。计划进行额外的测试工作,并将其与估算相结合。"

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.

冶金测试计划在工业技术研究中心(CTRI),总部设在鲁因-诺兰达,由Soutex Inc.(“Soutex”)监管。该计划的目标是提供初步冶金数据,以支持矿产资源评估的准备。这些测试包括定量矿物学分析、可磨性测试(以确定磨矿功率要求)和两(2)个磨矿水平(P80分别为75和40µm)的氰化试验。

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延伸矿床共钻了187个岩心孔(53,861米)。QPM目前正在钻探,以扩大La Pointe延伸矿藏(T.N:行情).参见2021年11月2日的新闻稿),为矿产资源评估做准备。La Pointe矿床的走向长度为950米,最小深度为700米,主要部分的真实厚度估计为35米。La Pointe延伸矿床的走向长度为3750米,最小深度为400米,估计真实厚度为39米(参见2021年6月9日的新闻稿)位于矿床的中心部分。矿床中部的平均真实厚度为39米,最高可达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.

从LaPointe和La Pointe伸展矿床中提取了六(6)个钻孔复合样品。这些样品的头部品位从1.0到3.6g/t Au不等。这些样品被认为在空间上代表了矿床和矿化的地质特征。

Mineralogical analysis

矿物学分析

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.

对每个样品进行了定量扫描矿物学分析(QEMSCAN),以测定其硫化物矿物含量,结果从1.9%到3.4%不等。原生硫化物有黄铁矿、磁黄铁矿和毒砂。这些样品的浓度水平不足以影响氰化过程。其他主要成分为石英和长石。

Grindability tests

研磨性试验

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.

从样品中测定了磨削结合功指数。这些值在9.1到11.1kWh/t之间变化。这些值被认为是中等的,这意味着与其他类似类型的矿石相比,磨矿所需的能量将处于中等范围。

Cyanidation tests

氰化试验

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.

氰化结果表明,当P80粒度从75µm降至40µm时,回收率显著提高,回收率的提高超过了预期的额外磨矿成本。36h后氰化钠消耗较低,约为0.4 kg/t,消石灰消耗为2 kg/t,浸出时间为36h,可获得最大回收率。在两个砷含量较高的样品上,40µm的P80对金的溶出率为91%,而对其他样品的溶出率分别为95%和99%。已经进行了额外的测试来评估黄金行为,例如诊断浸出测试。结果表明,用浮选或重量法补充氰化没有潜在的冶金改善作用。

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.

试验结果表明,最佳的提取方案是由破碎、磨矿、浸金组成的常规球磨流程。硫含量在1%~2%之间,硫化矿物类型对氰化过程无害。除硫化物外,还缺少有害成分。
