Key Terms

feasibility study, national instrument 43-101, value‑added tax, equity financings

4 terms

feasibility study technical

"Upon the public filing by Axo of a feasibility study respecting the Project..."

A feasibility study is an assessment that evaluates whether a proposed project or idea is practical and likely to succeed before investing significant time and resources. It considers factors like costs, potential benefits, and challenges, helping stakeholders decide if moving forward makes sense. Think of it as a detailed plan that gauges if a new venture is worth pursuing.

national instrument 43-101 regulatory

"prepared in accordance with National Instrument 43-101 – Standards of Disclosure..."

National Instrument 43-101 is a set of rules and guidelines that govern how mineral exploration and mining companies must report information about their projects. It ensures that the details shared with investors are accurate, consistent, and reliable—similar to how a detailed, verified blueprint ensures a building’s safety. This helps investors make informed decisions based on trustworthy information about a company's mineral resources.

value‑added tax financial

"A cash payment equal to 70% of any Mexican value‑added tax refund due or owing..."

A value-added tax (VAT) is a consumption tax charged on the incremental value added at each stage of producing and selling goods or services; businesses collect VAT from customers and remit the net amount to the government after subtracting the VAT they paid on purchases. It matters to investors because VAT affects pricing, profit margins, cash flow and consumer demand—think of it as a small toll at each step of a product’s journey that can change costs, sales and regulatory compliance risk.

equity financings financial

"upon Axo closing one or more equity financings that raise aggregate gross proceeds..."

Equity financings are when a company obtains money by selling new shares of its ownership to investors, like selling extra slices of a pie to bring in cash. For investors this matters because issuing more shares changes how much of the company each owner holds, can dilute existing holdings, and often affects the stock price and control of the business; the proceeds are typically used for growth, debt, or operations.

MONTREAL, Jan. 27, 2026 (GLOBE NEWSWIRE) -- Osisko Development Corp. (NYSE: ODV, TSXV: ODV) (collectively with its subsidiaries, "Osisko Development" or the "Company") is pleased to announce that it has completed the previously announced sale of its 100% interest in the San Antonio Gold Project ("San Antonio" or the "Project") located in Sonora State, Mexico, to Axo Copper Corp. ("Axo") through the sale of all of the issued and outstanding equity interests of Sapuchi Minera S. de R.L. de C.V. ("Sapuchi Mexico") (the "Transaction").

At closing, Osisko Development received 15,325,841 common shares of Axo ("Axo Shares"), representing 9.99% of the issued and outstanding common shares of Axo on a non‑diluted basis.

Osisko Development is entitled to certain contingent deferred payments in connection with the sale, including:

• A cash payment equal to 70% of any Mexican value‑added tax refund due or owing to Sapuchi Mexico in respect of any period ending on or before the closing date of the Transaction;
• Upon the public filing by Axo of a feasibility study respecting the Project that is prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects, US$2,000,000, payable in cash or up to 9,398,496 Axo Shares, at Axo's option, provided that if the issue price of such Axo Shares is below the November 21, 2025 closing price of the Axo Shares (the "Floor Price"), the Company will receive 9,398,496 Axo Shares plus a cash payment equal to the shortfall between US$2,000,000 and the US dollar-equivalent value of the Axo Shares received; and
• A cash payment of US$2,000,000, upon the first gold pour being completed at the Project.
  

In addition, upon Axo closing one or more equity financings that raise aggregate gross proceeds of at least US$10,000,000 (a "Qualifying Financing"), if the issue price is greater than the Floor Price, Axo would be required to issue to Osisko Development such number of Axo Shares that would result in Osisko Development retaining a 9.99% interest in Axo, on a non-diluted basis, on the initial US$10,000,000 raised. If the issue price is less than the Floor Price in connection with such issuance, Osisko Development will receive a maximum of 5,521,699 Axo Shares plus a cash payment equal to the issue price multiplied by the number of additional Axo Shares Osisko Development would have received if the additional shares were issued at the issue price instead of the Floor Price.

Bennett Jones LLP acted as legal advisor to Osisko Development in connection with the Transaction.
