VANCOUVER, BC / ACCESS Newswire / March 17, 2025 / Camino Minerals Corporation (TSXV:COR)(OTC PINK:CAMZF) (" Camino " or the " Company ") is pleased to provide an update on its previously announced ¹ acquisition (the " Proposed Transaction ") of all of the issued and outstanding shares of Cuprum Resources Chile SpA (" Cuprum "), which owns the construction-ready Puquios copper project located in Chile (the " Puquios Project "). The Company is pleased to announce that it has filed an independent technical report (the " Puquios Project Technical Report ") entitled " Puquios Project - NI 43-101 Technical Report and Pre-feasibilityStudy, La Higuera, Coquimbo Region, Chile " with respect to the Puquios Project, which is expected to be one of the Company's principal material properties for the purposes of Canadian securities laws upon completion of the Proposed Transaction.

The results of the PFS on the Puquios Project demonstrate a robust project, with low pre-production capital and capital intensity requirements and a strong production profile. Specifically, the Puquios Project Technical Report highlights an estimated project after-tax net present value (" NPV ") (8% discount rate) of US$118 million with an after-tax internal rate of return (" IRR ") of 23.4% at a fixed copper price of US$4.28 per pound. All in sustaining costs for the life of mine are projected at US$2.00 per pound.

" The transaction for the Puquios Project with partners Denham Capital and Nittetsu Mining from Japan, is expected to close during the first week of April 2025. The Puquios Project has received its primary environmental permit, Resoluciones de Calificacion Ambiental (RCA), to build and operate a mine, so following the closing of the transaction, we are ready to complete any outstanding sectoral permits and engineering studies and accelerate the project towards copper production, " stated Jay Chmelauskas, President and CEO of the Company. " Heap leach copper production is one of the most cost-effective ways to build a copper mine and these mines are very common in Northern Chile.The results of our PFS demonstrate robust economics in the current market for copper, providing the pathway for Camino to become a new copper producer and to realize our growth strategy that includes advancing our copper assets in Peru, " said Mr. Chmelauskas.

THE MEETING

Purpose of the Meeting

The purpose of the Meeting is to consider the items of business set forth in the notice of special meeting dated February 12, 2025 (the " Notice of Meeting "), which are, to approve, as more particularly described therein: (i) the Proposed Transaction and certain matters ancillary thereto; and (ii) the creation of Santiago Metals Investment Holdings II SLU and Santiago Metals Investment Holdings II-A LLC (being, the vendors disposing their interest in Cuprum to the Company under the Proposed Transaction) as new "Control Persons" (as such term is defined in the rules and policies of the TSX Venture Exchange) of the Company in connection with the Proposed Transaction.

CAMINO SHAREHOLDERS ARE URGED TO CAREFULLY REVIEW THE MEETING MATERIALS (AS DEFINED BELOW), INCLUDING THE NOTICE OF MEETING, THE CIRCULAR, and THE AMENDMENT, WHICH CONTAIN A DETAILED DESCRIPTION OF THE ITEMS OF BUSINESS TO BE CONSIDERED AT THE MEETING AND THE PROPOSED TRANSACTION, AS WELL AS OTHER IMPORTANT INFORMATION.

Key Benefits and Recommendation of the Board of Directors

The Company believes that it is acquiring the Puquios Project for less than the cost that it would otherwise take to bring a similar asset to the same stage of development, and in doing so, eliminating years from the project development timeline for a comparable copper asset. The Puquios Project is of a scale that the Company believes it could (together with its business partners, Denham Capital Management LP and Nittetsu Mining Co., Ltd.) build by sourcing the necessary funding from capital markets. The construction and operation of the Puquios Project is expected to provide synergies to the Company's other advanced exploration assets in Peru (particularly its Los Chapitos Project).

The independent members of the board of directors of the Company (the " Board ") (with Mr. Justin Machin abstaining due to the conflict of interest described in the Circular) unanimously support the Proposed Transaction on the basis that it is fair and in the best interest of the Company, as it will, among other things, add a construction-ready copper project to the Company's portfolio of properties.

THE BOARD UNANIMOUSLY (WITH MR. JUSTIN MACHIN ABSTAINING DUE TO THE CONFLICT OF INTEREST DESCRIBED IN THE CIRCULAR) RECOMMENDS THAT CAMINO SHAREHOLDERS VOTE FOR EACH OF THE MATTERS TO BE PRESENTED TO THE SHAREHOLDERS FOR APPROVAL AT THE MEETING WHICH ARE SET FORTH IN THE CIRCULAR.

AMENDMENTS TO MANAGEMENT INFORMATION CIRCULAR

Following the mailing and public filing of the Circular, the interim financial statements of Cuprum for the nine months ended September 30, 2024 (the " Cuprum Interim Financial Statements ") and the audited financial statements of Cuprum for the financial years ended December 31, 2023 and 2022 (the " Cuprum Annual Financial Statements ") originally included in Schedule E of the Circular were amended and reissued to include the basic net loss per share for the applicable periods presented in the said financial statements. In addition, the Cuprum Annual Financial Statements were amended and reissued to (i) revise Note 10 of the Cuprum Annual Financial Statements, in order to update the fair value of the identifiable assets acquired and liabilities assumed by Cuprum in connection with certain merger by absorption transaction (the " Proyecto Merger ") completed by Cuprum, and (ii) revise the statement of cash flows included in the Cuprum Annual Financial Statements to reflect the impact of the Proyecto Merger under the "Financing Activities" subheading therein.
