Rush Announces Completion of Arrangement with Myriad Uranium

We are proud to have completed this transaction with Myriad. The combination brings together complementary expertise and establishes a clear path forward for Copper Mountain. We believe Rush shareholders will benefit from continued exposure to the project through their shareholdings in Myriad, as well as from the separate value of Rush Spinco and its Boxi Property. Under the Arrangement, Myriad issued an aggregate of 24,983,671 Myriad common shares (each, a "Myriad Share") to Rush shareholders, representing approximately one (1) Rush Share to 0.5405 Myriad Shares (the "Exchange Ratio"). In addition, all outstanding Rush stock options were replaced with an aggregate of 2,110,120 Myriad stock options (each, a "Myriad Option"), with appropriate adjustments made to reflect the Exchange Ratio. The Arrangement was approved by the Rush shareholders at an annual general and special meeting held on August 17, 2026. On August 19, 2026, the Supreme Court of British Columbia issued the final order to approve the Arrangement. Following completion of the Arrangement, Rush has become a wholly owned subsidiary of Myriad, and the Rush Shares have been delisted from the Canadian Securities Exchange. As part of the Arrangement, Rush shareholders received an aggregate of 11,555,816 common shares ("Spinco Shares") of the wholly-owned subsidiary of Rush, 1577075 B.C. Ltd. ("Spinco"), representing one (1) Rush Spinco share for each four (4) Rush Shares outstanding. In exchange for the Spinco Shares, Rush transferred all of its right, title and interest in and to its Boxi Property in Quebec and has funded $100,000 to support the capitalization of Rush Spinco. Registered Rush shareholders should send their completed and executed letters of transmittal and their Rush share certificates to the depository, TSX Trust Company, as soon as possible in order to receive their Myriad Shares to which they are entitled under the Arrangement. Non-registered Rush shareholders who hold shares through a broker or another intermediary should follow the instructions provided to them by their broker or such other intermediary.
