Northern Superior Reports Positive Metallurgical Testing With Flotation Concentrate Recoveries up to 95.6%
Toronto, Ontario--(Newsfile Corp. - July 6, 2023) - Northern Superior Resources Inc. (TSXV: SUP) (OTCQX: NSUPF) ("Northern Superior" or the "Company") is pleased to report results from metallurgical testing conducted at SGS Laboratory from its Philibert gold deposit, located 60 kilometres southwest of Chibougamau, Québec, Canada (the "Philibert Project" - Northern Superior: 75%; SOQUEM: 25%).
安大略省多倫多-(Newsfile Corp.-2023年7月6日)-Northern Superior Resources Inc.(TSXV:SUP)(OTCQX:NSUPF)(北方優勝者“或”公司)很高興地報告在SGS實驗室對其飛利伯特金礦進行的冶金測試結果,該金礦位於加拿大QuéBEC奇布加莫西南60公里處(The飛利浦專案“-北方優勝:75%;SOQUEM:25%)。
Highlights Include:
亮點 包括:
- Arctic Fox South zone with 95.6% of the gold in 9.5% of mass;
- Arctic Fox North zone with 93.3% of the gold in 13.2% of mass; and
- Red Fox zone with 95.5% of the gold in 15% of mass.
- 北極狐南帶含金量95.6%,質量分數9.5%;
- 北極狐北帶含金量為93.3%,佔總質量的13.2%;和
- 紅狐區有95.5%的黃金佔15%的質量。
Simon Marcotte, President & Chief Executive Officer of Northern Superior, commented: "With such high recovery of the gold content in a flotation concentrate, recovering the gold in an efficient manner is not expected to be an issue. The gold recovery by flotation from all areas tested to date is favorable and increases our confidence that the Philibert Project demonstrates the right attributes to achieve strong potential economics in the future."
北方優品公司首席執行官兼首席執行官西蒙·馬科特表示:“由於浮選精礦中金含量的回收率如此之高,以高效方式回收黃金預計不會成為問題。迄今為止,通過浮選從所有地區回收黃金是有利的,並增強了我們的信心,即飛利浦專案展示了正確的屬性,在未來實現了強勁的潛在經濟效益。”
A metallurgical test program was completed on three composites from the Philibert deposit, where the main objective was to develop initial metallurgical data to evaluate if the style of mineralization is amenable to flotation followed by cyanidation. Results indicate that cyanidation of the tails may not be required.
完成了對飛利伯特礦床的三種化合物的冶金測試計劃,主要目的是開發初始冶金數據,以評估礦化類型是否適合浮選和氰化。結果表明,尾巴可能不需要氰化。
The 34 independent samples on halved NQ drill core used in the program were collected by GoldMinds Geoservices Inc. from the 2022 drilling campaign for sample preparation and gold analysis, head and composite analysis, flotation on three composites, cyanidation and flotation of tails. The three composites were selected from the hanging wall zone of the Philibert Project including the Arctic Fox South, Arctic Fox North, and Red Fox zones. The flotation metallurgical tests done on 2 kg test charges ground to P80 = 75 μm and subjected to flotation under typical conditions for sulphide flotation. The two flotation products were analyzed for gold ("Au"), silver ("Ag"), and sulphur ("S").
該專案中使用的34個NQ鑽芯上的獨立樣品是由GoldMinds Geoservices Inc.從2022年鑽探活動中收集的,用於樣品製備和黃金分析、頭部和化合物分析、三種化合物的浮選、氰化和尾礦浮選。這三個複合材料是從飛利浦專案的懸壁區中挑選出來的,包括北極狐南區、北極狐區和紅狐區。進行了2公斤試驗的浮選冶金試驗,磨礦P80=75μm,在典型的硫化物浮選條件下進行浮選。對這兩種浮選產品進行了黃金分析(“Au)、銀牌(銀)和硫磺(%s“)。
The evaluated samples ranged in head grade from 1.85 g/t Au (Composite 3) to 5.10 g/t Au (Composite 1). The silver content was <2 g/t in all three samples. The three composites responded well to sulphide flotation, with sulphide recoveries from 95% to 97%, gold recoveries from 93% to 96%, and silver recoveries from 38% to 68%, at between 10% and 15% mass recovery. Gold and silver contents in the flotation tails were very low at <0.2 g/t and <0.5 g/t, respectively.
被評估的樣品的頭部品位從1.85g/t Au(綜合3)到5.10 g/t Au(綜合1)。三個樣品中的銀含量均小於2g/t。三種化合物對硫化物浮選反應良好,硫化物回收率為95%~97%,金回收率為93%~96%,銀回收率為38%~68%,質量回收率為10%~15%。浮選尾礦中金和銀的含量很低,分別小於0.2g/t和
Because of the low gold and silver contents in the tails, it was decided to only carry out the cyanidation tests on the flotation concentrates. Cyanidation of the flotation concentrates yielded final gold extractions ranging from 91% (Composite 3) to 96% (Composite 1).
由於尾礦中金、銀含量較低,決定只對浮選精礦進行氰化試驗。通過對浮選精礦進行氰化處理,最終的金浸出率從91%(綜合3)到96%(綜合1)不等。
In Table 1 below, results for screened metallic analysis for Au and Ag by Fire Assay, Sulphur by Leco, whole rock analysis by ICP method, and Graphitic carbon. The head grade was calculated using a 500-gram spilt of the screen metallic analysis. The gold ore grades obtained corresponded well with the results of the calculated average gold grade for Composite 2 and Composite 3 (2.90 g/t versus 2.56 g/t for Composite 2 and 1.89 g/t versus 1.85 g/t for Composite 3). However, the calculated gold grade for Composite 1 was 2.77 g/t versus a grade of 5.10 g/t obtained by screened metallics analysis. The difference is likely due to sampling challenges and the presence of coarse particles of gold in the 500-gram charge used for the screened metallics analysis.
在下面的表1中,金和銀的火試金法、LECO法的硫、電感耦合等離子體法全巖分析和石墨炭的篩選金屬分析的結果。使用500克洩漏的篩分金屬分析來計算頭部等級。所獲得的金礦品位與綜合2和綜合3的平均金品位(2.90g/t對2.56g/t和1.89g/t對1.85g/t)的計算結果很好地吻合。然而,計算得到的複合材料1的金品位為2.77g/t,而篩選金屬分析得到的品位為5.10g/t。這種差異可能是由於採樣困難以及用於篩選金屬分析的500克裝藥中存在粗金顆粒。

The following conclusions can be drawn from the scoping test work on composite samples from the Philibert Project:
從對飛利浦專案複合材料樣品的範圍測試工作中可以得出以下結論:
- The three composites tested responded well to conventional sulphide flotation at primary grinds of 80-90 μm (P80), yielding >93% gold and sulphide recoveries in mass recoveries of 10-15%;
- The three flotation concentrates responded well to cyanidation at a regrind P80 of 50 to 60 μm, yielding gold recoveries of 91 to 96%. Cyanide consumptions of 1.5 to 2.3 kg/t NaCN were reasonable for concentrate leaching. These consumptions are equivalent to 0.18 to 0.23 kg/t NaCN on a whole mineralized zone basis;
- Overall gold recoveries via cyanidation of flotation concentrates were in the 86% to 92% range; and
- Despite the close association between gold and the sulphide minerals in the flotation process, the test work shows the gold in this deposit is not locked in the sulphides and is amenable to cyanidation.
- 在80~90μm(P80)的一次磨礦條件下,三種組合對常規硫化物浮選反應良好,金和硫化物的回收率均大於93%,質量回收率為10~15%;
- 三個浮選精礦在再磨P80為50~60μm時對氰化反應良好,金回收率為91~96%。精礦浸出的氰化物用量以1.5~2.3 kg/t NaCN為宜。按整個礦化帶計算,這些消耗量相當於0.18~0.23公斤/噸NaCN;
- 浮選精礦氰化提金的總體回收率在86%至92%之間;以及
- 儘管金在浮選過程中與硫化物礦物緊密結合,但試驗工作表明,該礦床中的金不鎖定在硫化物中,易於氰化。
