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.

哈利法克斯,NS/ACCESSWIRE/2023年8月24日/Silver Tiger Metals Inc.(多伦多证券交易所股票代码:SLVR)(场外交易市场代码:SLVTF)(以下简称“Silver Tiger”或“公司”)高兴地报告了其位于墨西哥索诺拉的高品位银金El Tigre项目(“El Tigre项目”)的初步范围冶金测试结果。本公司亦预期于2023年第三季度公布经更新及扩充的矿产资源估计及初步经济评估(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.

冶金试验工作
初步冶金研究表明,硫化物和黑色页岩带中银、金、铜、锌和铅的回收率较高,银当量回收率分别为95.7%和98.1%。新发现的高品位硫化物和黑色页岩带是最近钻探的重点,它们显示出巨大的勘探潜力,无论是横向还是深层都是开放的。

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.

此前对地表矿物区的钻探表明,矿化带的实际宽度超过100米。在柱试验中银当量回收率高达78.1%,模拟堆浸过程,公司看到了露天矿低成本堆浸过程的潜力。这一露天堆浸过程将被定义为即将到来的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.

本新闻稿中报告的结果涉及安大略省SGS Lakefield于2022年和2023年进行的关于表层矿物带的Au-Ag矿化和来自黑色页岩、硫化物带和高品位银脉的Ag-Au-Zn-Cu-Pb矿化的测试工作。预计将于2023年第三季度发布关于El Tigre矿床的最新和扩大的矿产资源评估和PEA。

Highlights Include:

亮点包括:

  • 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
  • 黑页岩带初步浮选试验回收铜91.1%、铅98.2%、锌98.8%、金91.9%、银98.4%。整体等值白银回收率-98.1%
  • 硫化带初步浮选试验回收铜94.2%、铅95.3%、锌97.6%、金79.6%、银96.0%。整体等值白银回收率-95.7%
  • 在3/8粉碎粒度(如图3所示的浸出剖面)中,表层堆积区柱试验回收了83.1%的金,64.3%的银,这些试验表明没有团聚的要求。整体等值白银回收-78.1百分比
  • 值得注意的还有每吨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."

总裁首席执行官兼首席执行官格伦·杰瑟姆表示:“根据硫化物、黑色页岩和地表矿物区的代表性样品,我们很高兴地报告银、金和贱金属的回收率非常高。对于硫化物和黑色页岩区的浮选试验,我们注意到地下矿床的磨矿过程中有96%至98%的总银当量的巨大回收率;对于露天堆浸柱试验,我们注意到银当量的平均回收率超过78%,对于低成本的浸出过程来说,这是一个高回收率。”

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先生进一步表示:“冶金学对于了解矿产项目的潜在经济效益至关重要,这些新的结果给了我们极大的鼓舞,即将到来的PEA可能会显示出地下和露天矿藏的强劲经济效益。”

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.

预计将于2023年第三季度发布关于El Tigre矿床的最新和扩大的矿产资源评估和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).

黑色页岩和硫化物浮选样品及测试
两(2)个钻孔复合材料被取样并运往SGS Lakefield进行浮选范围测试工作。如图1所示,这两个钻孔(ET-22-436,黑色页岩区;ET-22-443硫化物区)被粉碎,研磨到74微米,进行更粗的浮选,以生产两(2)种精矿--铜/铅(含金和银)和锌(含金和银)。

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.

采用标准浮选方法生产铜/铅精矿,同时压低锌,然后再进行锌浮选。优化回收和清洁精矿品位的测试正在进行中,最终确定后将报告。这项正在进行的测试将确认适销品等级,并确认产品的相关冶炼厂净收益(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.

关于银虎和El Tigre历史矿区
Silver Tiger Metals Inc.是一家加拿大公司,其管理层拥有25年以上在墨西哥发现、融资和建设大型热液银项目的经验。Silver Tiger 100%拥有的28,414公顷历史悠久的El Tigre矿区位于墨西哥索诺拉。有原则的环境、社会和治理实践是Silver Tiger的核心优先事项。

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历史矿区位于墨西哥索诺拉,位于马德雷山脉银金矿带的北端,拥有许多浅成热液银金矿床,包括北端的多洛雷斯、圣埃琳娜和拉斯奇斯帕斯。1896年,在金山地区的这块土地上首次发现了黄金,1903年,从布朗竖井开始采矿。很快,重点转向开采该地区的高品位银矿脉,生产来自三个平行矿脉:El Tigre矿脉、Seitz Kelley矿脉和Sooy矿脉。El Tigre中脉的地下开采沿着走向延伸了1450米,在14个层面上进行了开采,深度约为450米。Seitz Kelley矿脉沿着走向开采了1公里,深度约为200米。Sooy矿脉只沿着走向开采了250米,深度约为150米。随着大萧条的开始,白银价格暴跌至每盎司不到20美分,所有这些矿脉的开采都突然停止了。据报道,到1930年该矿关闭时,从187万吨中总共生产了353,000盎司黄金和6,740万盎司白银(Craig,2012)。在此期间开采的平均品位超过每吨2公斤银当量。
