VAULT STRATEGIC TRANSITIONS TO OTCID UNDER SYMBOL "KNXFF" WITH DTC ELIGIBILITY

Vault Strategic Mining Corp. has transitioned from the OTC Pink Market to the OTCID market operated by OTC Markets Group Inc.

The OTCID market is intended for companies committed to maintaining enhanced disclosure practices, including current financial reporting, management certifications and verified company profile updates. This elevated level of transparency strengthens investor confidence and broadens access to institutional and retail investors who require strong corporate disclosure standards. Vault believes this transition reinforces its continuing commitment to transparency and sound corporate governance.

Quinn Field-Dyte, chief executive officer and director, stated: "Listing on the OTCID is a natural step for Vault. It became clear that we needed to broaden how we share our story, particularly as interest grows in our U.S. historical mine portfolio. We see this as a key move to engage a wider investor base and support our growth strategy."

As previously announced on Oct. 21, 2025, the company's shares are eligible for electronic clearing and settlement in the United States through the Depository Trust Company (DTC). DTC eligibility streamlines the electronic trading process for U.S. investors by enabling faster and more efficient clearing and settlement of the company's common shares within the U.S. financial system.
