Minera Tres Valles SpA Has Filed an Application for Liquidation in Chile

TORONTO, Dec. 12, 2022 - (TSXV: TVC) (OTCQB: TVCCF) Three Valley Copper Corp. ("Three Valley Copper", "TVC" or the "Company") today announced that Minera Tres Valles SpA ("MTV"), the Company's 95.1% Chilean copper mining subsidiary, has filed an application for bankruptcy liquidation with the Civil Courts of Santiago. Under applicable Chilean law, a liquidator is expected to be appointed by the larger creditors of MTV in the coming days, and such liquidator will assume full responsibility for the operations and management of MTV. The public company, Three Valley Copper, is expected to continue as a going concern independent of the application for bankruptcy liquidation filed by MTV.

Upon appointment, the liquidator will carry out or exercise, as applicable, all acts, rights, and obligations of MTV and will be required to perform all acts necessary for the preservation of MTV's rights against its debtors and creditors.

Although MTV has sought creditors' protection by filing a Judicial Restructuring Procedure on June 13, 2022, the order has not yet been granted by the Chilean courts and MTV's liquidity position has continued to deteriorate.

Beginning in January 2022, MTV scaled down operations while the Company and MTV, together with the senior lenders to MTV, began a process to attract a long-term financing solution for MTV. To date, a long-term financing solution has not been sourced and there are no ongoing discussions with potential investors.

MTV has operated at a limited capacity since January 2022 while it continued to harvest copper cathodes from its current inventory. MTV forecasts an accelerating decline in its liquidity position as its current inventory is nearing depletion, and together with the substantial funding requirements to carry out a restart of operations, MTV is unable to effectively carry on its business or meet its obligations as they become due.

As a result of the foregoing, MTV has applied for voluntary liquidation with sufficient cash resources for the liquidator to manage MTV for several months in full care and maintenance. It is expected that employees dedicated to environmental compliance and general maintenance activities at MTV will remain. The majority of MTV's workforce was previously terminated and paid severance entitlements.

Following appointment of the liquidator, further information will be communicated to affected parties in accordance with applicable legislation.
