Three Valley Copper Postpones Interest Payment Due March 31, 2022

TORONTO, March 31, 2022 - (TSXV: TVC) (OTCQB: TVCCF) Three Valley Copper Corp. ("Three Valley Copper" or the "Company") confirms that its 95.1% indirectly owned subsidiary, Minera Tres Valles ("MTV") has not made the interest payments due on March 31, 2022, to its senior secured lenders (the "Lenders") as required pursuant to the terms of the amended loan facility. Certain loan principal repayments in 2022 have been deferred pursuant to an undertaking entered into between the Company and the Lenders on November 21, 2021.

As previously disclosed, the Company and MTV are in negotiations with the Lenders to find a longer-term solution to the financing requirements of MTV. A successful solution will enable MTV to continue operations and complete the ramp up of production of the Papomono mine over the upcoming twelve months. If approvals from the respective parties are not obtained and longer-term funding not provided, it is expected that MTV will not have sufficient funds to operate beyond April 2022.

As a result of the current financial situation of MTV, certain defaults of the senior secured debt facility have occurred and are continuing. While the Lenders have not provided a notice thereof to MTV, they have expressly reserved their rights.

The Company and MTV continue to preserve their cash resources during negotiations with the Lenders and other creditors and thank all stakeholders for their continued support and patience.

Cautionary Note to United States Investors Concerning Estimates of measured, indicated and inferred mineral resources

This news release may use the terms "measured", "indicated" and "inferred" mineral resources. Historically, while such terms were recognized and required by Canadian regulations, they were not recognized by the United States Securities and Exchange Commission (the "SEC"). The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the Securities and Exchange Act of 1934, as amended (the "Exchange Act"). These amendments became effective February 25, 2019 (the "SEC Modernization Rules") with compliance required for the first fiscal year beginning on or after January 1, 2021. The SEC Modernization Rules replace the historical property disclosure requirements for mining registrants that were included in SEC Industry Guide 7, which will be rescinded from and after the required compliance date of the SEC Modernization Rules. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of "measured", "indicated" and "inferred" mineral resources. In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be substantially similar to the corresponding Canadian Institute of Mining, Metallurgy and Petroleum definitions, as required by NI 43-101. Investors are cautioned that "Inferred mineral resources" have a great amount of uncertainty as to their existence, and as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or other economic studies. United States investors are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. United States investors are also cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable.
