蒙特利尔，2026 年 1 月 27 日（环球新闻）—— Osisko Development Corp.（纽约证券交易所代码：ODV，TSXV 代码：ODV）（与其子公司统称为 “ Osisko Development” 或 “ 公司”）欣然宣布已完成之前宣布的将其在墨西哥索诺拉州的圣安东尼奥金矿项目（“ 圣安东尼奥” 或 “ 项目”）的 100% 权益出售给 Axo Copper Corp.（“ Axo”）的交易，具体通过出售 Sapuchi Minera S. de R.L. de C.V.（“ Sapuchi Mexico”）的所有已发行和流通的股权（“ 交易”）。
在交易完成时，Osisko Development 收到了 15,325,841 股 Axo 普通股（“ Axo 股份”），这代表了 Axo 已发行和流通普通股的 9.99%（不稀释基础）。
Osisko Development 有权获得与此次出售相关的某些或有递延付款，包括：
<ul>
<li>一笔现金支付，等于 Sapuchi Mexico 在交易完成日期之前的任何期间应得或应收的 70% 的墨西哥增值税退款；</li>
<li>在 Axo 根据国家仪器 43-101 - _矿产项目披露标准_公开提交一份关于该项目的可行性研究后，支付 2,000,000 美元，现金支付或最多 9,398,496 股 Axo 股份，由 Axo 选择，前提是如果这些 Axo 股份的发行价格低于 2025 年 11 月 21 日 Axo 股份的收盘价（“ 底价”），公司将收到 9,398,496 股 Axo 股份以及一笔现金支付，等于 2,000,000 美元与收到的 Axo 股份的美元等值之间的差额；以及</li>
<li>在项目完成首次金锭铸造后，支付 2,000,000 美元的现金。</li>
</ul>
此外，在 Axo 完成一项或多项融资，筹集总额至少为 10,000,000 美元（“ 合格融资”）的情况下，如果发行价格高于底价，Axo 将被要求向 Osisko Development 发行足够数量的 Axo 股份，以使 Osisko Development 在初始筹集的 10,000,000 美元中保持 9.99% 的权益（不稀释基础）。如果在此类发行中发行价格低于底价，Osisko Development 将最多收到 5,521,699 股 Axo 股份，以及一笔现金支付，等于发行价格乘以如果额外股份以发行价格而非底价发行时 Osisko Development 将收到的额外 Axo 股份数量。

Phrases or statements that certain actions, events or results may, could, should or will be achieved, received or taken, or will occur or result and similar such expressions identify forward-looking statements. The words &#34;estimate&#34;, &#34;expects&#34; or &#34;would&#34; or variations of or similar such words and phrases or statements that certain actions, events or results may, could, should or will be achieved, received or taken, or will occur or result and similar such expressions identify forward-looking statements.

There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements, including the risk that the sale transaction will not be completed for any reason and that the contingent deferred payments are actually paid to Osisko Development. Forward-looking statements are provided for the purpose of providing information about management's expectations and plans relating to the future. All of the forward-looking statements made in this news release are qualified by this cautionary statement and those made in our other filings with the securities regulators of Canada and the United States including, but not limited to, the cautionary statements made in the &#34;Risk Analysis&#34; section of our MD&amp;A for the three and nine months ended September 30, 2025 and the Annual Information Form dated March 28, 2025.
