HALIFAX, NS / ACCESSWIRE / August 24, 2023 / Silver Tiger Metals Inc. (TSXV:SLVR)(OTCQX:SLVTF) ("Silver Tiger" or the "Corporation") is pleased to report gold and silver extraction results from initial scoping-level metallurgical test work from its high-grade silver-gold El Tigre Project in Sonora, Mexico (the "El Tigre Project"). The Corporation also expects to release an updated and expanded mineral resource estimate and Preliminary Economic Assessment (PEA) in Q3 2023.

哈雷法克斯,NS/ACCESSWIRE/2023年8月24日/Silver Tiger Metals Inc.(多倫多證券交易所股票代碼:SLVR)(場外交易市場代碼:SLVTF)(以下簡稱“Silver Tiger”或“公司”)高興地報告了其位於墨西哥索諾拉的高品位銀金El Tigre專案(“El Tigre專案”)的初步範圍冶金測試結果。本公司亦預期於2023年第三季度公佈經更新及擴充的礦產資源估計及初步經濟評估(PEA)。

METALLURGICAL TEST WORK
Preliminary metallurgical work demonstrates excellent recoveries of silver, gold, copper, zinc and lead in the Sulphide and Black Shale Zones with silver equivalent recoveries of 95.7% and 98.1%, respectively. The newly discovered, high-grade Sulphide and Black Shale Zones have been the focus of recent drilling and they show great exploration potential being open both laterally and at depth.

冶金試驗工作
初步冶金研究表明,硫化物和黑色葉巖帶中銀、金、銅、鋅和鉛的回收率較高,銀當量回收率分別為95.7%和98.1%。新發現的高品位硫化物和黑色葉巖帶是最近鑽探的重點,它們顯示出巨大的勘探潛力,無論是橫向還是深層都是開放的。

Previous drilling of the Surface Stockwork Zone has indicated a mineralized zone in excess of 100 meters true width. With high recoveries of 78.1% silver equivalency in column testing, simulating a heap leaching process, the Corporation sees the potential for an open pit low-cost heap leach process. This open pit heap leach process will be defined as part of the upcoming PEA.

此前對地表礦物區的鑽探表明,礦化帶的實際寬度超過100米。在柱試驗中銀當量回收率高達78.1%,類比堆浸過程,公司看到了露天礦低成本堆浸過程的潛力。這一露天堆浸過程將被定義為即將到來的PEA的一部分。

Results reported in this news release pertain to test work conducted by SGS Lakefield in Ontario in 2022 and 2023 on the Au-Ag mineralization from the Surface Stockwork Zone and Ag-Au-Zn-Cu-Pb mineralization from the Black Shale, Sulphide Zones and High-Grade Silver Veins. An updated and expanded mineral resource estimation and PEA for the El Tigre deposit is expected to be released during Q3 2023.

本新聞稿中報告的結果涉及安大略省SGS Lakefield於2022年和2023年進行的關於表層礦物帶的Au-Ag礦化和來自黑色葉巖、硫化物帶和高品位銀脈的Ag-Au-Zn-Cu-Pb礦化的測試工作。預計將於2023年第三季度發佈關於El Tigre礦床的最新和擴大的礦產資源評估和PEA。

Highlights Include:

亮點包括:

  • Preliminary rougher flotation tests of the Black Shale Zone recovered 91.1% copper, 98.2% lead, 98.8% zinc, 91.9% gold, and 98.4% silver. Overall Silver Equivalent Recovery - 98.1%
  • Preliminary rougher flotation tests of the Sulphide Zone recovered 94.2% copper, 95.3% lead, 97.6% zinc, 79.6% gold, and 96.0% silver. Overall Silver Equivalent Recovery - 95.7%
  • Surface Stockwork Zone column test extractions recovered - 83.1% Gold, 64.3% Silver at 3/8-in crush size (leach profile shown in Figure 3) with no requirement for agglomeration indicated in these tests. Overall Silver Equivalent Recovery - 78.1%
  • Also notable is the low cyanide consumption of 0.68 kg per tonne and lime consumption of 2.33 kg per tonne
  • 黑葉巖帶初步浮選試驗回收銅91.1%、鉛98.2%、鋅98.8%、金91.9%、銀98.4%。整體等值白銀回收率-98.1%
  • 硫化帶初步浮選試驗回收銅94.2%、鉛95.3%、鋅97.6%、金79.6%、銀96.0%。整體等值白銀回收率-95.7%
  • 在3/8粉碎粒度(如圖3所示的浸出剖面)中,表層堆積區柱試驗回收了83.1%的金,64.3%的銀,這些試驗表明沒有團聚的要求。整體等值白銀回收-78.1百分比
  • 值得注意的還有每噸0.68公斤的低氰化物消耗量和2.33公斤的石灰消耗量

Glenn Jessome, President and CEO, stated: "Based on representative samples from the Sulphide, Black Shale and Surface Stockwork Zones, we are pleased to report very high silver, gold and base metal recoveries. For flotation tests of the Sulphide and Black Shale Zones we note tremendous recoveries of 96 to 98% total silver equivalency for the milling process on the underground deposit; and for the open pit heap leach column tests we note that silver equivalency recoveries average above 78%, which represents a high recovery for a low-cost leaching process."

總裁首席執行官兼首席執行官格倫·傑瑟姆表示:“根據硫化物、黑色葉巖和地表礦物區的代表性樣品,我們很高興地報告銀、金和賤金屬的回收率非常高。對於硫化物和黑色葉巖區的浮選試驗,我們注意到地下礦床的磨礦過程中有96%至98%的總銀當量的巨大回收率;對於露天堆浸柱試驗,我們注意到銀當量的平均回收率超過78%,對於低成本的浸出過程來說,這是一個高回收率。”

Mr. Jessome further stated: "Metallurgy is critically important to understanding the potential economics of a mineral project and these new results give us great encouragement that the upcoming PEA may show robust economics for the underground and open pit deposits."

Jessome先生進一步表示:“冶金學對於瞭解礦產專案的潛在經濟效益至關重要,這些新的結果給了我們極大的鼓舞,即將到來的PEA可能會顯示出地下和露天礦藏的強勁經濟效益。”

Estimated and Expanded Mineral Resource Estimate and PEA
An updated and expanded mineral resource estimation and PEA for the El Tigre deposit is expected to be released during Q3 2023.

估算與擴展礦產資源估算與PEA
預計將於2023年第三季度發佈關於El Tigre礦床的最新和擴大的礦產資源評估和PEA。

Black Shale and Sulphide Flotation Samples and Testing
Two (2) drill hole composites were sampled and shipped to SGS Lakefield for the flotation scoping test work. Shown in Figure 1, these two drill holes (ET-22-436, Black Shale Zone; ET-22-443 Sulphide Zone) were crushed, ground to 74 microns and subjected to rougher flotation to produce two (2) concentrates - copper/lead (with gold and silver) and zinc (with gold and silver).

黑色葉巖和硫化物浮選樣品及測試
兩(2)個鑽孔複合材料被取樣並運往SGS Lakefield進行浮選範圍測試工作。如圖1所示,這兩個鑽孔(ET-22-436,黑色葉巖區;ET-22-443硫化物區)被粉碎,研磨到74微米,進行更粗的浮選,以生產兩(2)種精礦--銅/鉛(含金和銀)和鋅(含金和銀)。

Standard flotation methods were carried out to produce the copper/lead concentrate while depressing the zinc followed by a zinc flotation. Testing to optimize recovery and cleaner concentrate grades is underway and will be reported when finalized. This ongoing testing will confirm marketable grades and confirm associated net smelter return (NSR) of the products.

採用標準浮選方法生產銅/鉛精礦,同時壓低鋅,然後再進行鋅浮選。優化回收和清潔精礦品位的測試正在進行中,最終確定後將報告。這項正在進行的測試將確認適銷品等級,並確認產品的相關冶煉廠淨收益(NSR)。

About Silver Tiger and the El Tigre Historic Mine District
Silver Tiger Metals Inc. is a Canadian company whose management has more than 25 years' experience discovering, financing and building large epithermal silver projects in Mexico. Silver Tiger's 100% owned 28,414 hectare Historic El Tigre Mining District is located in Sonora, Mexico. Principled environmental, social and governance practices are core priorities at Silver Tiger.

關於銀虎和El Tigre歷史礦區
Silver Tiger Metals Inc.是一家加拿大公司,其管理層擁有25年以上在墨西哥發現、融資和建設大型熱液銀專案的經驗。Silver Tiger 100%擁有的28,414公頃歷史悠久的El Tigre礦區位於墨西哥索諾拉。有原則的環境、社會和治理實踐是Silver Tiger的核心優先事項。

The El Tigre historic mine district is located in Sonora, Mexico and lies at the northern end of the Sierra Madre silver and gold belt which hosts many epithermal silver and gold deposits, including Dolores, Santa Elena and Las Chispas at the northern end. In 1896, gold was first discovered on the property in the Gold Hill area and mining started with the Brown Shaft in 1903. The focus soon changed to mining high-grade silver veins in the area with production coming from 3 parallel veins the El Tigre Vein, the Seitz Kelley Vein and the Sooy Vein. Underground mining on the middle El Tigre vein extended 1,450 meters along strike and was mined on 14 levels to a depth of approximately 450 meters. The Seitz Kelley Vein was mined along strike for 1 kilometer to a depth of approximately 200 meters. The Sooy Vein was only mined along strike for 250 meters to a depth of approximately 150 meters. Mining abruptly stopped on all 3 of these veins when the price of silver collapsed to less than 20¢ per ounce with the onset of the Great Depression. By the time the mine closed in 1930, it is reported to have produced a total of 353,000 ounces of gold and 67.4 million ounces of silver from 1.87 million tons (Craig, 2012). The average grade mined during this period was over 2 kilograms silver equivalent per ton.

El Tigre歷史礦區位於墨西哥索諾拉,位於馬德雷山脈銀金礦帶的北端,擁有許多淺成熱液銀金礦床,包括北端的多洛雷斯、聖埃琳娜和拉斯奇斯帕斯。1896年,在金山地區的這塊土地上首次發現了黃金,1903年,從布朗豎井開始採礦。很快,重點轉向開採該地區的高品位銀礦脈,生產來自三個平行礦脈:El Tigre礦脈、Seitz Kelley礦脈和Sooy礦脈。El Tigre中脈的地下開採沿著走向延伸了1450米,在14個層面上進行了開採,深度約為450米。Seitz Kelley礦脈沿著走向開採了1公里,深度約為200米。Sooy礦脈只沿著走向開採了250米,深度約為150米。隨著大蕭條的開始,白銀價格暴跌至每盎司不到20美分,所有這些礦脈的開採都突然停止了。據報道,到1930年該礦關閉時,從187萬噸中總共生產了353,000盎司黃金和6,740萬盎司白銀(Craig,2012)。在此期間開採的平均品位超過每噸2公斤銀當量。
