Three Valley Copper Initiates Strategic Review and Updates Preliminary 2022

Operating Guidance

TORONTO, Oct. 20, 2021 (GLOBE NEWSWIRE) -- (TSXV: TVC) Three Valley Copper Corp. (“ Three Valley Copper ” or the

“Company”) has initiated a strategic review process to explore alternatives for the enhancement of shareholder value and the

best way forward to maximize production and cash flows from its mining assets in Chile. The Company’s primary asset is its

91.1% owned Minera Tres Valles (“MTV”) property near Salamanca, Region de Coquimbo, Chile.

Strategic Review

The Company and its Board have initiated a strategic review process that encompasses an evaluation of the Company's

development strategy, business plan, market valuation and capital structure and will consider numerous opportunities or

alternatives for the Company. These considerations may include potential mergers, a strategic partner(s), acquisitions or

dispositions, restructuring or refinancing of its long-term debt, and any other options identified with the fundamental objective of

achieving the best value for the Company's shareholders.

The Company has retained PI Financial to review and evaluate potential alternatives that may further maximize value for Three

Valley Copper’s shareholders. There can be no assurance that the Company's strategic review process will result in any

transaction or investment.

Achieving the 2022 production profile at MTV through its ramp-up of Papomono Masivo (“ PPM”) continues to be the

Company’s main priority. The ramp-up will establish the foundation from which the mining operation at MTV can expand to full

production. Following this, Three Valley Copper could recognize the associated operating benefits and further advance its

exploration efforts. The Company’s current exploration program has been temporarily scaled back pending the strategic review

process.

Revised 2022 Outlook and Guidance

The successful development of PPM continues to be the catalyst for the Company to maximize value of the MTV assets. The

positive construction advances experienced over the prior two months are expected to continue at PPM. However, the

management team at MTV has recently reviewed again its preliminary development and mining plans for PPM and has

concluded the best way to improve the net economic value of PPM is to increase its capital expenditures in 2022 rather than

defer some of these into the latter years of the mine life. Consequently, the Company is now forecasting that additional capital

of approximately US$10 million in 2022 will be required to achieve the mine production guidance recently announced.

Previously, the Company had anticipated that copper production from the Don Gabriel open pit mine together with the recent

drawdown of the remaining US$6 million of senior debt, which was completed in early September, would support current

operations and its ongoing PPM construction project. The Don Gabriel mine has to date experienced lower head grades than

forecasted. A number of remedial measures were introduced in the third quarter but the improved results in the mining

operation will take a number of months to appear due to the workflow of a heap leach operation. As the Company’s primary

source of ore to produce copper cathodes for 2021, the underperformance in Don Gabriel production has amplified the

Company’s tight liquidity position with the loss of this revenue and is compounded by having a mostly fixed operating cost

base, increased capital demands of the PPM 2022 development and scheduled debt repayments which are due to begin

March 2022. The Company does not expect that it will generate sufficient cash from operations to fully fund 2021 continuing

operations, planned investment activities and debt service obligations and the revised increased sustaining capital

expenditures required in 2022 for PPM.

The Company is currently in discussions with its senior secured lenders and offtake provider and foresees a continuing

successful partnership with them that may include a number of changes to its existing loan agreement, inter alia, bridge loan

financing, waivers of operating covenants, deferrals of or renegotiation of repayment terms and/or renegotiation of the fixed

price portion of the offtake agreement. At this time there can be no assurance that such actions will be granted by the senior

lenders and/or offtake provider and the Company will continue to report on the progress of such discussions.

The Company has now updated its operating guidance below, which assumes a successful event from its strategic review

and/or negotiations with its senior secured lenders that will provide the Company with sufficient liquidity to allow it to execute

its production expansion at MTV as intended.

The Company’s revised preliminary operating outlook1 for 2022 at MTV is as follows:

    Revised Original

  Operating information Year Ended Year Ended

  Copper (MTV Operations) Dec. 31, 2022 Dec. 31, 2022

  Cu Production (tonnes) 8,000 – 10,000 8,000 – 10,000

  Cu Production (pounds) 17.6M – 22.0M 17.6M – 22.0M

  Cash Cost per Pound Produced2 $2.75 - $3.25 $2.75 - $3.25

  Capital Expenditures3 ($ millions) $15 - $20 $5 - $10

In the absence of a successful strategic review event and/or renegotiations with its senior secured lenders which will require

financial liquidity solutions for MTV before the end of 2021, additional material changes to the Company’s revised preliminary

outlook above will then be required.

1. Preliminary guidance is based on certain estimates and assumptions, including but not limited to, mineral reserve

estimates, grade and continuity of interpreted geological formations, metallurgical performance and foreign exchange

rates. Please refer to the amended and restated technical report prepared by Wood Independent Mining Consultants,

Inc., in respect of the Minera Tres Valles Copper Project (the “Technical Report”) dated May 27, 2021 and to the

Company’s SEDAR filings for complete risk factors related to the Company and MTV.

2. Cash Cost is a non-IFRS measure – Cash costs of production include all costs absorbed into inventory less non-cash

items such as depreciation. Cash costs per pound produced are calculated by dividing the aggregate of the applicable

costs by copper pounds produced.

3. Planned capital expenditures (“CAPEX”) for 2022 are focused primarily on open pit expansion, plant CAPEX and

sustaining CAPEX of PPM for the inclined block-caving mining project. It is expected that by early 2022, the

underground operation at PPM will begin production and the resulting production growth is expected to lower per unit

operating costs in 2022 and 2023 as the results of this CAPEX are realized.

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.
