Camino Announces Filing of Pre-Feasibility Study Technical Report and Provides

Update on Previously Announced Acquisition of the Puquios Copper Project

Vancouver, BC – 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 -

feasibility Study, 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, t he 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.

Separately, the Company also announces that it has filed an amendment (the “Amendment”) to its

management information circular dated February 12, 2025 (the “Circular”) previously filed in respect of its

special meeting (the “Meeting”) of shareholders (the “Camino Shareholders ”) to be held on Monday,

March 31, 2025 at 10:00 a.m. (Vancouver time) , in order to provide shareholders with supplementary

financial information in respect of Cuprum and revise certain financial information in respect of Cuprum

originally included in the Circular.

Inferred 660 0.295 0.133 0.059 2

Notes:

1. Mineral Resources are classified using the 2014 CIM Definition Standards.

2. The Qualified Person for the estimates is Mr. Cristian Quiñones, RM CMC, AsGeoMin SpA.

3. Mineral Resources have an effective date of March 8, 2021.

4. Mineral Resources are reported using a cut-off grade of 0.15% total copper (CuT).

5. Mineral Resources are constrained by preliminary pit shells derived using a Lerchs–Grossmann algorithm and the following

assumptions: six geotechnical domains (52.3° to 59.8°); mining cost of US$2.10/t mined, processing cost of US$5.69/t

processed, including general and administrative (G&A) costs; variable processing recoveries derived from four regression

models; and a metal price of US$3.45/lb Cu.

6. Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade, and

contained metal content. Metal content based on CuT.

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 comp arable copper asset. The Puquios Project is of a scale that the

LEGAL*67578594.10

- 4 -

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 p rovide 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

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.

Following the mailing and public filing of the Circular, the management’s discussion and analysis of Cuprum

for the three and nine months ended September 30, 2024 was also amended to (i) restate the table under

the heading “Selected Financial Information” therein , and (ii) correct the amount of working capital of

Cuprum as at September 30, 2024.

The Amendment amends the Circular in order to give effect to the foregoing changes. Except as expressly

provided in the Amendment, the Amendment is in addition to, and not in replacement of, the original Circular
