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.
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.
The El Tigre silver and gold deposit is related to a series of high-grade epithermal veins controlled by a north-south trending structure cutting across the andesitic and rhyolitic tuffs of the Sierra Madre Volcanic Complex within a broad silver and gold mineralized prophylitic alteration zone developed in the El Tigre Formation that can be up to 150 meters wide. The veins dip steeply to the west and are typically 0.5 meter wide but locally can be up to 5 meters in width. The veins, structures and mineralized zones outcrop on surface and have been traced for 5.3 kilometers along strike in our brownfield exploration area. Historical mining and exploration activities focused on a 1.5 kilometer portion of the southern end of the deposits, principally on the El Tigre, Seitz Kelly and Sooy veins. The under explored Caleigh, Benjamin, Protectora and the Fundadora exposed veins continue north for more than 3 kilometers. Silver Tiger has delivered its maiden 43-101 compliant resource estimate and is currently drilling to update its resource estimate and publish a PEA.
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.

Mineral Resource Estimate and Technical Report (NI 43-101)
El Tigre Resource Estimate
After acquiring El Tigre, Silver Tiger drilled 12,500 meters to define the halo of near surface gold mineralization around the mined high-grade veins of the historic El Tigre Mine. This allowed Silver Tiger to deliver a maiden resource estimate for the El Tigre Property to a depth of 150 meters containing indicated resources of 661,000 gold equivalent ounces at 0.77 g/t (21 g/t silver and 0.51 g/t gold) and inferred resources of 341,000 gold equivalent ounces at 1.59 g/t (88 g/t silver and 0.52 g/t gold). The complete National Instrument 43-101 technical report is available on the company’s website below under Mineral Resource Estimate and Technical Report and on SEDAR under the company’s profile.

Notes to El Tigre Project Mineral Resource Estimate:
(1) El Tigre Deposit Mineral Resources are comprised of the El Tigre and Seitz Kelly Veins.
(2) Fundadora Deposit Mineral Resources are comprised of the Aquila, Fundadora, Protectora and Caleigh Veins.
(3) El Tigre Tailings Deposit Mineral Resources are comprised of the tailings from the former El Tigre operation.
(4) Mineral Resources are reported within a constraining pit shell.
(5) The Mineral Resource Estimate is reported in accordance with the Canadian Securities Administrators
National Instrument 43-101 and has been estimated using the CIM “Estimation of Mineral Resources
and Mineral Reserves Best Practice Guidelines and CIM “Definition Standards for Mineral Resources
and Mineral Reserves.
(6) Au:Ag ratio = ($1250/$17)/(70% Ag Rec/80% Au Rec)= 84:1 Therefore, AuEq=(Ag/84) + Au
(7) Mineral Resources in this estimate are based on approx. two year trailing average metal prices of
US$1,250 oz Au and US$17 /oz Ag, estimated process recoveries 80% Au and 70% Ag, US$5.70/t
process cost and US$0.80/t G&A cost. Mining costs of US$1.55/t for open pit and $45/t for underground
and tailings mining costs of US$5.50/t were used to derive the respective Mineral Resource Estimate
AuEq cut-offs of 0.20 g/t and 1.5 g/t and 0.37g/t. Pit optimization slopes were 50 degrees
(8) The Mineral Resource Estimate uses drill hole data available as of September 1, 2017.
(9) Totals may not add correctly due to rounding.
(10) An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral
Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of
Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued
exploration.
(11) 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, sociopolitical, marketing or other relevant issues.

Cautionary Note to US Investors
The disclosure on this Website has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of United States securities laws. Disclosure, including scientific or technical information, has been made in accordance with Canadian National Instrument 43-101 -- Standards of Disclosure for Mineral Projects ("NI 43-101"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. As a result, information contained on this Website containing descriptions of the mineral properties or estimates of mineral reserves or resources of Silver Tiger is not comparable to similar information disclosed by U.S. companies in reports filed with the SEC.
For example, the terms "measured mineral resources", "indicated mineral resources", "inferred mineral resources", "proven mineral reserves" and "probable mineral reserves" are used on this Website to comply with the reporting standards in Canada. While those terms are recognized and required by Canadian regulations, the SEC does not recognize them.
Under the rules and regulations of the SEC set forth in Industry Guide 7, a U.S. company may only disclose estimates of proven and probable mineral reserves, and may not disclose estimates of any classification of mineral resources. In addition, the definitions of proven and probable mineral reserves used in NI 43-101 differ from the definitions in the SEC Industry Guide 7. Under United States standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Investors are cautioned not to assume that all or any part of the mineral deposits in these categories will ever be converted into mineral reserves. Any estimate of mineral reserves or resources has a great amount of uncertainty as to its existence, and great uncertainty as to its economic and legal feasibility with estimates of mineral resources having a greater degree of uncertainty. It cannot be assumed that all or any part of measured mineral resources, indicated mineral resources or inferred mineral resources will ever be upgraded to a mineral reserve or mined. Further, in accordance with Canadian rules, estimates of inferred mineral resources cannot form the basis of feasibility or other economic studies. Investors are cautioned not to assume that any part of the reported measured mineral resources, indicated mineral resources, or inferred mineral resources on this Website will ever be classified as a reserve. Disclosure of "contained ounces" is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute reserves as in place tonnage and grade without reference to unit measures.
