STRIA PROVIDES UPDATE ON CHANGE OF BUSINESS TRANSACTION & ANNOUNCES BOARD APPOINTMENT

Stria Lithium Inc. has provided an update regarding the proposed acquisition of a net smelter return (NSR) royalty of up to 2 per cent on the advanced Western Australian Mt. Henry gold project, pursuant to an investment agreement with Alicanto Minerals Ltd. This agreement, which was initially announced in the company's news release dated April 8, 2026, led to Stria's proposed change of business from a mining exploration company to an investment issuer. The parties have recently amended the investment agreement and have agreed to an extension expiring on July 28, 2026, to complete the acquisition.

Shortly following the execution of the investment agreement, Stria paid to Alicanto a non-refundable deposit of $1-million (Australian) ($978,700 (Canadian)) to be applied to the $5-million (Australian) cash consideration of the royalty on closing. The deposit was requested by Alicanto and deemed necessary for Stria in order to secure this cornerstone investment of its proposed change of business strategy. The investment agreement and the deposit were made in anticipation of a change of business under Policy 5.2 without the prior approval of the TSX Venture Exchange and, as such, remain subject to the TSX-V approval.

On May 18, 2026, Alicanto released on the Australian Securities Exchange strong assays from its first drilling program at the Mt. Henry gold project in Norseman, Western Australia. This drilling intersected thick sulphide-bearing BIF mineralization outside the current resource footprint, extending known mineralization at both the Mt. Henry and Selene deposits within the Mt. Henry gold project (refer to Stria's news release dated April 8, 2026, for details of the historical measured and indicated resource on the project).

The acquisition remains subject to several conditions, including obtaining all necessary regulatory and corporate approvals, including that of the TSX Venture Exchange, the filing on SEDAR+ under Stria's issuer profile of a listing statement supporting Stria's change of business and a technical report compliant with National Instrument 43-101, Standards of Disclosure for Mineral Projects, on the Mt. Henry gold project, among other customary closing conditions. The acquisition will require shareholder approval under the policies of the exchange, which the company anticipates receiving by way of written resolution of its shareholders. These conditions are all expected to be completed in the coming weeks and the company expects to return to trading shortly thereafter.

Stria continues to advance the various components required under exchange Policy 5.2, Changes of Business and Reverse Takeovers. Work related to the acquisition, including technical reporting, preparation of the filing statement and assembly of required regulatory filings, is progressing and Stria confirms having filed with the exchange a listing application in connection with its proposed change of business along with a draft filing statement and technical report for review and comment.

The parties remain committed to moving the acquisition forward in order to complete the transaction before the end date and will provide further updates as appropriate. Additional details of the acquisition, as contemplated in the investment agreement between Stria and Alicanto, may be found in the company's news release dated April 8, 2026.

Name change

In connection with the company's change of business and concurrently with the completion of the acquisition, the company plans to change its name to Arc Mineral Royalties Ltd. On June 9, 2026, Stria held an annual and special meeting of shareholders and, notably, successfully obtained shareholder approval in connection with the proposed change of name of the company.

Investment policy

In connection with the company change of business, the board of directors will adopt and implement an investment policy that will guide the company's transition to a mining royalty and streaming business. The policy will be focused on generating attractive risk-adjusted returns through the acquisition of royalties, streams and other investment interests, primarily in the precious metals sector, while preserving capital through portfolio diversification.

The company's initial focus will be on gold and other precious metals, with a strategy of building a diversified portfolio of royalty and streaming assets across the natural resources sector. Investments may include royalties, streams, equity, debt, joint venture interests and other investment structures, with opportunities evaluated on their risk-reward profile and long-term value creation potential.

The company intends to reinvest cash flow and investment returns to support the continued growth of its portfolio and does not currently anticipate paying dividends during its early stages of development. The overarching objective is to establish a scalable, diversified portfolio of royalty and streaming assets that provides shareholders with exposure to precious metals and long-term value creation.
