We recognise the work completed by the Fox River team to advance the project to its current stage. This proposed acquisition aligns with Avenir Minerals' desire to maintain a disciplined, phased approach to project advancement with a strong focus on responsible stewardship and respectful engagement with communities and Indigenous Peoples.

Certain of the statements and information in this news release constitute "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 and "forward-looking information" within the meaning of applicable Canadian provincial securities laws. Forward-looking statements and information can be identified by statements that certain actions, events or results "could", "may", "should", "will" or "would" be taken, occur or achieved. All statements, other than statements of historical fact, are forward-looking statements or information. Forward-looking statements or information in this news release relate to, among other things: the proposed acquisition by Avenir Minerals of all of the Fox River Shares and the terms thereof; statements regarding the anticipated benefits of the Transaction for Fox River; the anticipated filing of materials on SEDAR+; the approval of the Transaction by Fox River Shareholders; regulatory approvals and closing conditions to the Transaction; the expected date of completion of the Transaction; the expectation that the Fox River Shares will be delisted from the CSE and that Fox River will cease to be a reporting issuer under applicable Canadian securities laws and other statements that are not historical fact.

The forward-looking statements and information contained in this news release reflect Fox River's current views with respect to future events and are necessarily based upon a number of assumptions that, while considered reasonable by Fox River, are inherently subject to significant operational, business, economic and regulatory uncertainties and contingencies.

Fox River cautions the reader that forward-looking statements and information involve known and unknown risks, uncertainties and other factors that may cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements or information contained in this news release and Fox River has made assumptions and estimates based on or related to many of these factors. In addition, in connection with the forward-looking statements contained in this press release, Fox River has made certain assumptions, including the ability of the parties to receive, in a timely manner and on satisfactory terms, the necessary regulatory, court and shareholder approvals; the ability of the parties to satisfy, in a timely manner, the other conditions for the completion of the Transaction, and other expectations and assumptions concerning the proposed Arrangement. The anticipated dates indicated may change for a number of reasons, including the necessary regulatory, shareholder and court approvals, the necessity to extend the time limits for satisfying the other conditions for the completion of the proposed Arrangement or the ability of the Board to consider and approve, subject to compliance by Fox River of its obligations under the Arrangement Agreement, a superior proposal for Fox River. Among the key factors that could cause actual results to differ materially from those projected in the forward-looking financial information and statements are the following: the failure of the parties to obtain the necessary shareholder, regulatory and court approvals or to otherwise satisfy the conditions for the completion of the Transaction; failure of the parties to obtain such approvals or satisfy such conditions in a timely manner; significant transaction costs or unknown liabilities; the ability of the Board to consider and approve, subject to compliance by Fox River with its obligations under the Arrangement Agreement, a superior proposal for Fox River; the failure to realize the expected benefits of the Transaction; the effect of the announcement of the Transaction on the ability of Fox River to retain and hire key personnel and maintain business relationships; the market price of the Fox River Shares and business generally; potential legal proceedings relating to the Transaction and the outcome of any such legal proceeding; the inherent risks, costs and uncertainties associated with transitioning the business successfully and risks of not achieving all or any of the anticipated benefits of the Transaction, or the risk that the anticipated benefits of the Transaction may not be fully realized or take longer to realize than expected; the occurrence of any event, change or other circumstances that could give rise to the termination of the Arrangement Agreement and general economic conditions. Failure to obtain the necessary shareholder, regulatory and court approvals, or the failure of the parties to otherwise satisfy the conditions for the completion of the Transaction or to complete the Transaction, may result in the Transaction not being completed on the proposed terms or at all. In addition, if the Transaction is not completed, and Fox River continues as an independent entity, there are risks that the announcement of the Transaction and the dedication of substantial resources by Fox River to the completion of the Transaction could have an impact on its business and strategic relationships, including with future and prospective employees, customers, suppliers and partners, operating results and activities in general, and could have a material adverse effect on its current and future operations, financial condition and prospects. Additional risks, uncertainties and other factors are identified in Fox River's most recent management's discussion and analysis, which has been filed with the Canadian provincial securities regulatory authorities, as applicable.

Although Fox River has attempted to identify important factors that could cause actual results to differ materially from those set out or implied by the forward-looking statements and information, this list is not exhaustive and there may be other factors that cause results not to be as anticipated, estimated, described or intended. Investors should use caution when considering, and should not place undue reliance on any, forward-looking statements and information.
