Silver Tiger Added to GDXJ Junior Gold Miners ETF and Provides Construction Update

Silver Tiger Metals Inc. (SLVR) announced its inclusion in the VanEck Junior Gold Miners ETF (GDXJ), effective at the close of markets on September 18, 2026, following the fund's quarterly rebalance. The GDXJ tracks the MVIS Global Junior Gold Miners Index and held approximately US$9.3 billion in assets under management with more than 110 holdings as of early September 2026.

The company also provided a construction update for its 100%-owned El Tigre Project in Sonora, Mexico, confirming that the project remains on schedule for commissioning and first pour in December 2027. On-site workforce numbers exceed 250 people, with 219,000 man-hours logged since construction began.

Progress on key infrastructure and engineering milestones includes:

• Detailed engineering by KCA and KCN under the EPCM contract is 65% complete.
• Mine operations camp installation is 50% complete.
• Road improvements on the 46 km Colonia Morelos to El Tigre road are 85% complete.
• Earthworks for heap leach, ponds, process plant platforms and crusher platforms are 30% complete.
• Procurement of long-lead items is complete, including the crusher plant, conveyor and stacking system, and Merrill-Crowe plant and refinery.

CEO Glenn Jessome stated that inclusion in the ETF should raise the company's profile, support trading liquidity, and broaden institutional and retail reach.

Silver Tiger Metals Inc. (SLVR) issued a non-earnings, operations and listing update that confirms no new financial results, resource or reserve updates, capital expenditure changes, or shifts to the December 2027 first-pour timeline. The company’s inclusion in the GDXJ is viewed as positive for liquidity and passive-index demand, though it does not constitute a first-time strategic cornerstone investment, an M&A event, or a change to project economics.

Construction progress remains consistent with prior disclosures. Compared with the July 8, 2026 update, road improvements have advanced from 25% to 85%, earthworks have begun and reached 30%, camp installation is 50% complete, and engineering is 65% complete. This represents expected execution rather than a new derisking event.

The most recent prior release, dated September 11, 2026, reported high-grade drill results from the northern veins; however, those results are not part of this September 14 release and do not render the GDXJ or construction news material on their own. Financial context from the latest reported statements shows no revenue, no debt, cash of C$69.27 million at December 31, 2025, and accumulated losses. The company remains pre-production. Overall, the release is positive but incremental and expected, presenting no genuinely new, market-moving fundamental information.
