Vault Strategic Mining establishes subsidiary for U.S. historical mine portfolio

Vault Strategic Mining Corp. Announces Plan To Establish Wholly Owned Subsidiary For U.S. Historical Mine Portfolio

(TheNewswire)

Vancouver, British Columbia - July 3, 2026 - TheNewswire - Vault Strategic Mining Corp. (TSXV: KNOX) (OTC: KNXFF) (FSE: M850) (WKN: A41WE4)  ("Vault" or the "Company") is pleased to announce that the Company intends to form a wholly owned subsidiary to hold, manage, and advance its portfolio of U.S.-based historical mine assets as part its broader project portfolio review.

The proposed subsidiary is expected to provide Vault with a dedicated corporate structure for its U.S. historical mine portfolio, including its critical mineral-focused assets in the United States. The Company believes this structure will support operational efficiency, project-level planning, and future engagement with U.S.-based strategic partners, agencies, contractors, and industry participants focused on strengthening domestic critical mineral supply chains.

Vault also announces that it intends to apply for a Unique Entity ID (“UEI”) through SAM.gov. The UEI is used within the U.S. federal system to identify entities that seek to engage with federal contracting, assistance, and other government-related programs. Subject to the completion of applicable registrations and approvals, the Company believes this process may position Vault and/or its proposed U.S. subsidiary to better evaluate opportunities connected to U.S. critical mineral initiatives.

“Establishing a dedicated subsidiary for our U.S. historical mine portfolio is an important step in organizing these assets for future growth,” said Quinn Field-Dyte, Chief Executive Officer of Vault Strategic Mining. “As governments continue to prioritize secure domestic sources of critical minerals, Vault is taking practical steps to ensure the Company is positioned to engage with potential U.S. government, industry, and strategic partners where appropriate.”

The Company’s U.S. historical mine portfolio is focused on strategic mineral assets located in established mining jurisdictions with historical production or exploration activity. Vault’s objective is to evaluate these assets using modern exploration techniques, build a stronger technical understanding of their potential, and assess opportunities that may support the development of resilient North American critical mineral supply chains.

The Company cautions that the formation of the proposed subsidiary, the application for a UEI, and any related registrations remain subject to completion. There can be no assurance that the Company will receive any government funding, contract, grant, strategic partnership, or other benefit as a result of these initiatives.

Amendment to Letain Nickel Project Agreement

The Company also announces that it has entered into an amending agreement with 1240089 BC Ltd. and 1258713 BC Ltd. in respect of the Letain Nickel Project mineral claims purchase and sale agreement, originally made effective February 10, 2025. Pursuant to the amendment, certain remaining project payments under the agreement will be satisfied 50% in cash and 50% in common shares of the Company, with the share portion priced at the closing price of the Company’s common shares on the trading day immediately prior to the applicable payment due date.

The amended payment structure applies to the outstanding project payments currently contemplated under the agreement, including the $50,000 second-anniversary payment and the $115,000 third-anniversary payment. As amended, the $50,000 payment will be satisfied as to $25,000 in cash and $25,000 in common shares, and the $115,000 payment will be satisfied as to $57,500 in cash and $57,500 in common shares, in each case based on the applicable closing price.

The amendment does not change the timing of the applicable project payments and does not amend the original share consideration, quarterly royalty payments, or any royalty repurchase or buy-down payments, unless otherwise expressly agreed to in writing by the parties. The issuance of any shares pursuant to the amendment remains subject to applicable securities laws, exchange acceptance or approval, if required, and any applicable hold periods or resale restrictions. Except as expressly amended by the amending agreement, the original agreement remains unchanged and in full force and effect.

Amendment to Robinson Dyke Property Option Agreement

The Company also announces that it has entered into an amendment agreement with American Mining Claims LLC in respect of the Robinson Dyke Property, being one of the properties subject to the Mineral Property Option Agreement dated January 14, 2026 among American Mining Claims LLC, Stream Metals LLC and Vault Strategic Mining Corp.

The amendment also reduces the net smelter returns royalty payable to American Mining Claims LLC upon exercise of the Robinson Dyke option from 2.5% to 1.5%. Vault or its assignee will have the right, exercisable at any time in one transaction, to purchase and extinguish the entirety of the royalty for a one-time cash payment of US$1,000,000.

Pursuant to the amendment, the parties have agreed to increase the aggregate Robinson Dyke option payments by $2,500, from $15,500 to $18,000. The increase will be paid in five additional monthly instalments of $500 each, and all monthly payments previously made by Vault to American Mining Claims LLC under the original agreement will be credited against the amended aggregate payment amount.

Strategic Prioritization of War Bond Tungsten Project

The Company also announces that, following due diligence, including its recently expanded exploration program at the War Bond, Thursday and Tactite historical tungsten mines in Nevada, it has determined to prioritize the War Bond Tungsten Project in terms of the Company’s tungsten exploration effort. Based on the Company’s technical review, field work, strategic assessment and capital allocation priorities, Vault believes that focusing its near-term exploration efforts on War Bond provides the clearest path to advancing its U.S. tungsten strategy.

As part of this strategic prioritization, the Company has determined that it will no longer pursue further exploration or its option on the Wheeler Tungsten Project (announced Jan 21, 2026) and the Mirage-Mariposa Tungsten Project (announced May 8, 2026). The Company intends to focus its technical, operational and financial resources on the War Bond Tungsten Project and other assets within its portfolio that management believes are best aligned with Vault’s strategy of advancing high-priority critical mineral opportunities in North America.
