Vista Gold Highlights Mt Todd Progress and Announces Participation in Australia’s Diggers & Dealers Mining Forum

Vista Gold Corp. (NYSE American and TSX: VGZ) today provided an update on its Mt Todd gold project ("Mt Todd" or the "Project") in Australia's Northern Territory and announced the Company’s participation in the Diggers & Dealers Mining Forum in Kalgoorlie, Western Australia.

Frederick H. Earnest, President and CEO of Vista Gold, commented, "Since announcing the results of the 2025 Mt Todd Feasibility Study, we have focused on advancing our standalone development strategy and have made significant progress on permitting, strengthening our Australian project leadership team, and completing key technical and planning initiatives. These activities are expected to reduce development risk, enhance project readiness, and position Mt Todd to begin detailed engineering and design in 2027. We expect this milestone to initiate an approximately 27-month period encompassing detailed engineering, construction, and commissioning of a new gold mine."

Advancing Permitting and Driving Development Forward

The Company continues to advance the permit modifications required to align existing approvals with the 2025 Mt Todd Feasibility Study (“Mt Todd FS”). The Company is actively engaged with regulators, consultants, and stakeholders to obtain permit modifications. Some modifications have already been submitted, the first authorizations already granted, and programs to support other submissions are in progress. Vista expects certain additional approvals to be granted in the second half of 2026 with final approvals anticipated in 2027.
