Silver Tiger Intersects 2.1 Metres of 7.72 Kilograms Per Tonne Silver Equivalent in the Caleigh Vein Including 0.53 Metres of 29.62 Kilograms

Silver Tiger Metals Inc. (SLVR) released results from its 2026 Summer Program drilling on the Northern Area of its 100%-owned El Tigre silver-gold project in Sonora, Mexico. The program targeted the Caleigh and Protectora Veins and a newly defined Northern Stockwork Zone, alongside confirmatory 2025 geotechnical drilling within the heap-leach pit area.

Key intercepts reported include:

• ET-26-649 Caleigh Vein: 2.1 m grading 7,715.1 g/t AgEq or 102.87 g/t AuEq from 39.9 to 42.0 m, consisting of 35.39 g/t Au and 5,061.1 g/t Ag; includes 0.53 m grading 29,620.0 g/t AgEq or 394.93 g/t AuEq from 40.40 to 40.93 m, consisting of 136.20 g/t Au and 19,405.0 g/t Ag.
• ET-26-643 Protectora/Stockwork: 93 m grading 70.1 g/t AgEq or 0.93 g/t AuEq from 16.9 to 109.9 m; includes 0.60 m grading 2,292.2 g/t AgEq or 30.56 g/t AuEq from 44.2 to 44.8 m.
• ET-26-638 Protectora/Stockwork: 15.5 m grading 101.9 g/t AgEq or 1.36 g/t AuEq from 20.7 to 37.8 m; includes 0.65 m grading 1,457.0 g/t AgEq or 19.40 g/t AuEq from 22.5 to 23.15 m.
• Geotechnical ET-26-632 inside proposed pit: 1.0 m grading 1,137.5 g/t AgEq or 15.17 g/t AuEq from 20.5 to 21.5 m, consisting of 15.10 g/t Au and 5 g/t Ag.

The release also reports all 14 exploration holes and 8 geotechnical holes in tables, not only the best intervals.

Silver Tiger Metals Inc. (SLVR) is a development-stage company with a market value of C$549 million, C$69.3 million in cash on its latest reported balance sheet, and no revenue. The company’s primary value driver is the El Tigre heap-leach project, which is targeted for first pour in December 2027 and is supported by a pre-feasibility study (PFS) and an underground preliminary economic assessment (PEA).

The recent release does not change the current mineral resource or reserve. The Northern Veins and stockwork are located outside the present PFS/PEA resource area, but they represent potential upside that could extend mine life or add a future satellite resource. The combination of a near-surface bonanza-grade Caleigh vein and multiple broad stockwork intersections increases the perceived scale and optionality of the project.

The stock has recovered from a 52-week low of C$0.66 to C$1.08, but remains below its January 2026 high of C$1.33. Some optimism regarding northern exploration is already reflected in the August-September rally, meaning the result is not entirely unpriced. However, the grade and breadth of the intersections are strong enough to be materially positive.

Silver Tiger Metals Inc. is a Canadian-listed silver-gold developer whose primary asset is the 100%-owned El Tigre Project in Sonora, Mexico, covering more than 37,000 hectares. The district has a history of producing 353,000 ounces of gold and 67.4 million ounces of silver from 1.87 million tons.

The company’s current development plan focuses on a heap-leach mine at the El Tigre Stockwork Zone, for which it has secured an EPCM contract with Kappes, Cassidy & Associates. Commissioning and the first doré pour are targeted for December 2027.

Prior-period context from earlier releases includes the following financial metrics:

• January 2026 Stockwork Zone PFS reported an after-tax NPV of US$456 million and an IRR of 65.7%.
• January 2026 underground PEA reported an after-tax NPV of US$304 million and an IRR of 42.8%.

The latest reported balance sheet shows 508,598,141 shares outstanding and cash of C$69,265,751.
