THIS NEWS RELEASE IS NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

April 29, 2026 – Vancouver, British Columbia – Kodiak Copper Corp. (the “Company” or “Kodiak”) (TSXV: KDK, OTCQX: KDKCF, Frankfurt: 5DD1) announces that it has entered into a non-binding letter of intent (the “LOI”) with Teck Resources Limited (collectively with its subsidiary Teck American Incorporated, “Teck”) and Kay Copper Corp. (“Kay Copper”, formerly Railtown II Capital Corporation), currently an unlisted reporting issuer, on February 17, 2026 which outlines the principal terms of a proposed transaction to be completed by way of a three-cornered amalgamation (the “Transaction”).

Under the Transaction, Kodiak would vend its 100% owned Mohave project (“Mohave”) and Teck would vend its 100% owned Copper Hill project (“Copper Hill”), both located in Arizona, into a subsidiary of Kay Copper to create a new US-focused copper exploration company that would apply to list its shares on the TSX Venture Exchange (“TSXV”). The Transaction is subject to ongoing negotiations, the execution of definitive agreements, due diligence, consents and regulatory approval, approval of the TSXV and the completion of the NewCo Initial Financing (as defined below) and NewCo Concurrent Financing (as defined below). There is no guarantee that the Transaction will be completed.

Strategic Rationale

Transaction is anticipated to generate synergies and unlock value that is not being recognized within current corporate structures
Conducive environment for domestic critical mineral projects in the United States
Premier jurisdiction – Arizona is a prolific mining district with existing infrastructure that produced 70% of US copper production in 2025
Quality assets – two 100% owned exploration-stage copper porphyry projects
Near-term exploration upside – multiple drill-ready targets on both projects that can be advanced quickly, with drilling planned in 2026
Experienced team with track record of creating shareholder value
Kay Copper is expected to be a well funded company with Teck and Kodiak as shareholders and the support of Discovery Group^TM

Claudia Tornquist, President and CEO of Kodiak said, “While Kodiak remains firmly focused on the MPD project in British Columbia, we are excited to combine our Mohave project with Teck’s Copper Hill project in a new company, Kay Copper. We are thrilled to become shareholders in Kay Copper alongside Teck and are confident this new venture has the potential to create substantial long-term shareholder value. With two projects with multiple targets ready to be drilled this year, Kay Copper will be well positioned to pursue a strategy of growth and value creation.”

Transaction Overview

Pursuant to the LOI and subject to the negotiation and execution of definitive agreements:

A new private company will be incorporated (“NewCo“) for the purposes of the Transaction. NewCo would acquire Mohave and Copper Hill from Kodiak and Teck respectively, in exchange for shares of NewCo;
NewCo would issue to each of Kodiak and Teck 20 million common shares at a deemed price of $0.25 per share as consideration for Mohave and Copper Hill, respectively. The $0.25 share price is a deemed price for transaction purposes only and does not represent a valuation;
NewCo would complete a three-cornered amalgamation with Kay Copper (the “Amalgamation”), whereby Newco would merge with a newly formed subsidiary of Kay Copper and the holders of shares of Newco would receive one share of Kay Copper for each Newco share held;
Concurrently with the Amalgamation, Kay Copper would apply to list its shares for trading on the TSXV under the name of Kay Copper Corp;
Completion of the Transaction is subject to customary closing conditions including the completion of due diligence by each of Kodiak, Teck and Kay Copper, negotiating and executing definitive agreements, obtaining all necessary consents and regulatory approvals, TSXV acceptance and satisfaction of applicable listing requirements, the completion of the NewCo Initial Financing (as defined below) and NewCo Concurrent Financing (as defined below) and other conditions. Closing is expected in the third quarter of 2026; and
Further details regarding the Transaction will be provided as the process continues to advance.

There can be no assurance that the Transaction, NewCo Initial Financing (as defined below) or NewCo Concurrent Financing (as defined below) will be completed as proposed, or at all.

NewCo Concurrent & Initial Financing

In connection with the Transaction, NewCo intends to complete a subscription receipt financing at $0.25 per share for minimum gross proceeds of C$4.0 million (the “NewCo Concurrent Financing”).

Proceeds are intended to fund exploration work programs to materially advance both projects in 2026.
Gross proceeds would be held in escrow and released concurrently with closing of the Transaction upon satisfaction of specified escrow release conditions, including completion of the asset acquisitions, Amalgamation, and TSXV conditional approval, and all requisite corporate and regulatory approvals.
If escrow release conditions are not satisfied, subscription receipt holders would be entitled to a return of funds in accordance with the terms of the subscription receipts.

In addition to the NewCo Concurrent Financing, NewCo intends to complete a non-brokered initial financing to the incoming management, board, and investors at $0.10 per share for gross proceeds of up to $830,000 (the “NewCo Initial Financing”), subject to negotiation, execution of definitive agreements, TSXV approval, including review of pricing and insider participation, and other applicable approvals. The NewCo Initial Financing is expected to close prior to closing of the Transaction.

Expected Capital Structure of Kay Copper

Following completion of the Transaction, the NewCo Concurrent Financing, and the NewCo Initial Financing, Kay Copper is expected to have approximately 70,300,000 common shares outstanding, on an undiluted basis, with ownership expected to be held approximately as follows:

Kodiak: 28%
Teck: 28%
Kay Copper existing shareholders: 9%
NewCo Initial Financing subscribers: 12%
NewCo Concurrent Financing subscribers: 23%

Final capitalization will be determined upon negotiation and execution of definitive agreements, the NewCo Concurrent Financing and the NewCo Initial Financing.

Additional Terms

In addition to receiving common shares of Kay Copper, each of Teck and Kodiak are expected to enter into separate Investor Rights Agreements with Kay Copper.
Teck is expected to be granted offtake rights with respect to certain concentrate production from the Mohave and Copper Hill projects, subject to definitive documentation.

Copper Hill Project Overview

35 km² land package in Arizona, located in a prolific porphyry district near a producing mining cluster (Christmas and Chilito) (Figure 1)
Limited historic exploration in the 1960s and 1970s identified prospective alteration and chemistry in drill holes and mapping
At least three large porphyry centres with potassic alteration & veining identified on the property

About Kodiak Copper

Kodiak is focused on advancing its 100%-owned MPD copper-gold porphyry project in the prolific Quesnel Terrane in south-central British Columbia, Canada, an established mining region with producing mines and existing infrastructure. MPD exhibits all the hallmarks of a large, multi-centered porphyry district with the potential for future economic development. The initial Mineral Resource Estimate, published in 2025, outlines seven substantial deposits and underscores the scale and potential of the project. All known deposits remain open to expansion, and numerous targets across the property have yet to be tested. Kodiak continues to systematically explore MPD’s district-scale potential with the goal of delivering new discoveries and building further critical mass toward being the region’s next mine.

Kodiak’s founder and Chairman, Chris Taylor, is well-known for his gold discovery success with Great Bear Resources. Kodiak is also part of Discovery Group^TM led by John Robins, one of the most successful mining entrepreneurs in Canada.
