Overview

Silver Tiger Metals Inc. is a Canadian company whose management has more than 25 years’ experience discovering, financing and building large hydrothermal 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.

  • In 2016 acquired the El Tigre concessions covering over 28,000 hectares for 11 million dollars CDN
  • In 2019 purchased the 6283 hectares of land that contain the concessions where the majority of the exploration has been conducted for 1.1 million USD
  • Silver Tiger has raised 75 million dollars CDN in 4 bought deal financings since 2020
  • Cash balance of C$24,500,000 as of the quarter ended June 30, 2023
  • Silver Tiger has drilled over 100,000 meters at El Tigre
  • Underground rehabilitation and slashing of the main portal for approximately 370 meters at an opening size of 4.0 meters by 4.5 meters
  • MRE released in September 2023 has delineated approximately 86.0 Moz AgEq or 1.2 Moz AuEq Indicated, and 90.3 Moz AgEq or 1.2 Moz AuEq of Inferred
  • Preliminary Economic Assessment (PEA) delivered Nov 1st
  • High-grade mineralization at the El Tigre Project is open both down dip and along strike with the disclosed Exploration Potential Target at 7 to 9 Million tonnes at 225 to 265 g/t AgEq for 50 to 75 Moz AgEq.

Notes:

1. Mineral Resources which are not Mineral Reserves, do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

2. The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.

3. The Mineral Resources in this news release were estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines (2014) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council and CIM Best Practices (2019).

Historically mined areas were depleted from the Mineral Resource model.

Approximately 74.7% of the Indicated and 22.3% of the Inferred contained AgEq ounces are pit

constrained, with the remainder out-of-pit. See tables 2 and 3 for details of the split between pit constrained and out-of-pit deposits.

6. The pit constrained AuEq cut-off grade of 0.14 g/t was derived from US$1,800/oz Au price, US$24/oz Ag price, 80% process recovery for Ag and Au, US$5.30/tonne process cost and US$1.00/tonne G&A cost. The constraining pit optimization parameters were $1.86/t mineralized mining cost, $1.86/t waste mining cost and 50-degree pit slopes.

7. The out-of-pit AuEq cut-off grade of 1.5 g/t AuEq was derived from US$1,800/oz Au price, US$24/oz Ag price, $4.00$/lb Cu, $0.95 $/lb Pb, $1.40 $/lb Zn, 85% process recovery for all metals, $50/t mining cost, US$20/tonne process and US$4 G&A cost. The out-of-pit Mineral Resource grade blocks were quantified above the 1.5 g/t AuEq cut-off, below the constraining pit shell within the constraining mineralized wireframes and exhibited sufficient continuity to be considered for cut and fill and long hole mining.

No Mineral Resources are classified as Measured.

AgEq and AuEq calculated at an Ag/Au ratio of 75:1.

Totals may not agree due to rounding

History of the El Tigre Mine District & Geological Journal Articles

The El Tigre Property lies at the northern end of the Sierra Madre gold belt which hosts many epithermal gold and silver deposits including Dolores, Santa Elena and 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 much of the production coming from the El Tigre vein.  Underground mining on the El Tigre vein extended 1,450 meters along strike and mined on 14 levels to a depth of 450 meters.   By the time the mine closed in 1938, 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.
