VISTA GOLD ANNOUNCES INCLUSION IN THE RUSSELL 2000 INDEX AND RUSSELL 2000 GROWTH INDEX

Vista Gold Corp. has been included in the list of additions to the small-capitalization Russell 2000 Index and the Russell 2000 Growth Index as part of the June, 2026, semi-annual Russell U.S. Indexes reconstitution, according to information published by FTSE Russell following the U.S. market close on Friday, May 22, 2026.

Final index membership is expected to become effective after the market close on Friday, June 26, 2026, subject to FTSE Russell's final reconstitution schedule and updates. The newly reconstituted Russell U.S. Indexes are expected to commence trading at the market open on Monday, June 29, 2026.

"Inclusion in the Russell 2000 Index and the Russell 2000 Growth Index is a meaningful milestone that reflects Vista's increased valuation and growing liquidity," said Frederick H. Earnest, president and chief executive officer of Vista. "The progress we've made to position and advance Mount Todd as a leading gold development project and increase awareness among shareholders has been a significant contributor. We believe inclusion in these indexes will further broaden our exposure to institutional and retail investors."

The Russell 2000 Index measures the performance of the small-cap segment of the U.S. equity market and is widely used by investment managers and institutional investors for index funds and as a benchmark for active investment strategies. Inclusion in the indexes may result in a short-term volume increase for a company's shares as funds and other investment products that track Russell indexes rebalance their portfolios.

About Vista Gold Corp.

Vista holds the Mount Todd gold project, located in the Tier 1 mining jurisdiction of Northern Territory, Australia. Mount Todd is among the largest development-stage projects in Australia. The company has defined a clear pathway to value realization, targeting the commencement of detailed engineering and design in 2027. This milestone is expected to initiate an approximately 27-month period of design, construction and commissioning, culminating in first gold production.

Mount Todd offers strong project economics, significant initial production, and compelling expansion and exploration upside. Mount Todd benefits from advanced local infrastructure, options for future expansion and broad community support, underpinning its potential to become a long-lived, globally significant gold operation.

We seek Safe Harbor.
