Three Valley Copper Commences Papomono Block Caving Operations

Corporate Updates

Three Valley Copper Commences Papomono Block Caving Operations

TORONTO, March 07, 2022 -- (TSXV: TVC) (OTCQB: TVCCF) Three Valley Copper Corp. (“ Three Valley Copper ” or the

“Company”) is pleased to report the start of its Papomono block caving operation at its 95.1% owned Minera Tres Valles

(“MTV”) property near Salamanca, Region de Coquimbo, Chile.

Papomono Start of Block Caving Operations

The Company, with the support of MTV’s senior secured lenders and underground mining contractor, has decided to start the

operations of the Papomono block caving mine while discussions with its senior secured lenders continue. The start of

operations allows the Company to retain its current mining contractor with its knowledge and experience of the operations and

avoid the cost of demobilization. The contractor has remained onsite since operations were halted in January allowing for an

immediate start to block caving operations at Papomono.

The senior secured lenders have reiterated their continued support of MTV and are working with the Company and MTV to

realize the robust economics from this underground mine. As part of the decision process to start the block caving operation

and at the request of the senior secured lenders, MTV engaged consultants to undertake a technical optimization study in

respect of Papomono. Phase one of this study has been completed and it supports the decision to start the operations of the

Papomono block caving mine.

As a result, the senior secured lenders, together with the Company, have expressed their intention to provide $11 million of

super senior secured funds to MTV, the approvals for and terms of which are being finalized. This funding, if approved, is

expected to be drawn down in tranches by MTV beginning at the end of March 2022 and is expected to fund MTV into July

2022 providing the Company and the senior secured lenders additional time to negotiate a longer-term solution for MTV,

including sourcing additional capital that will be required. If approvals from the respective parties are not obtained and funding

not provided, it is expected that MTV will not have sufficient funds to operate beyond April 2022. In addition to the $11 million,

the Company estimates that MTV will require at least an additional $10 million of capital during 2022.

MTV will continue to operate in a limited capacity during the ramp-up of Papomono by processing third-party ore. The

Company’s review of the Don Gabriel open pit operation continues, and at the current time, it does not expect that Don Gabriel

will be restarted in 2022. An analysis of Don Gabriel is ongoing and further information will be disclosed when available.

As a result of the current financial situation of MTV and the interruption in its operations, certain defaults of the senior secured

debt facility have occurred and are continuing. The senior secured lenders have not provided a notice thereof to MTV and

discussions continue to find a longer-term solution to the financing requirements of MTV.

The Company and MTV continue to preserve their cash resources during negotiations with MTV’s senior secured lenders and

other creditors and thank all stakeholders for their continued support and patience.

Joe Phillips, COO, Retirement

Michael Staresinic, CEO of Three Valley Copper stated, “With his continual focus on execution, Joe has helped lead MTV to

prioritize what is most important to its success, namely, the completion of the initial construction and development of the

Papomono underground mine. Joe accomplished what he said he was going to do and after a distinguished career in mining,

will be focusing his next stage of life on family and helping other companies grow through directorships and advisory positions.

We are grateful for Joe’s hard work and dedication to MTV and are very pleased he will remain as a director of both Three

Valley Copper and MTV to provide stewardship and important transitional continuity to the Papomono project as MTV ramps

up production from Papomono.”

Over his 50-year career, Mr. Phillips has directed the construction, commissioning, and operation of 11 plants and mining

operations, all of which met or exceeded their designed capacities, across 13 countries on 5 continents. He has held senior

executive positions including Chief Operating Officer, Chief Restructuring Officer, Chief Development Officer, amongst others,

across several US and Canadian mining companies. Mr. Phillips' retirement will be effective in the spring and a successor will

be announced at a later date.

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.
