(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - October 30, 2025) - Rush Rare Metals Corp. (CSE: RSH) (" Rush " or the " Company ") confirms that the letter of intent dated August 6, 2025, outlining a potential merger with Myriad Uranium Corp. ("Myriad") has expired. Rush continues to engage in discussions with Myriad regarding a potential transaction, with the goal of finding mutually agreeable terms moving forward.

Peter Smith, Rush's CEO, commented, "As a founder of both Rush and Myriad, I am very happy to see that both companies will continue merger discussions, but I have also been removed from this process since August 6^th to avoid any potential conflicts. I understand that our independent committee has been working hard towards an agreement, but there are a number of moving parts to administer, including the procurement of a fairness opinion, and this has caused some delay. Meanwhile, Myriad continues to make outstanding progress with Copper Mountain in Wyoming, and I am thrilled with the work Thomas Lamb and his team have done. I expect further updates will be forthcoming as the respective teams try to work through prospective merger terms and timings."
