A news release announcing the material change was disseminated via Canada Newswire on July 31, 2024 and a copy was filed on Silvercorp's profile at www.sedarplus.ca.

On July 31, 2024, Silvercorp completed its acquisition of all of the issued and outstanding common shares (each, an “Adventus Share”) in the capital of Adventus Mining Corporation (“Adventus”) not already owned by Silvercorp.

Silvercorp completed its acquisition of all of the Adventus Shares not already owned by Silvercorp effective as of 12:01 a.m. (the “Effective Time”) on July 31, 2024, by way of a statutory plan of arrangement under the provisions of the Canada Business Corporations Act (the “Arrangement”).

Under the terms of the Arrangement, each former shareholder of Adventus, other than Silvercorp, is entitled to receive 0.1015 of one common share in the capital of Silvercorp (each, a “Silvercorp Share”) for each Adventus Share (the “Exchange Ratio”). All outstanding stock options and common share purchase warrants of Adventus are now exercisable for Silvercorp Shares, with the number of Silvercorp Shares issuable on exercise and the exercise price adjusted in accordance with the Exchange Ratio. All outstanding Adventus restricted share units vested as of the Effective Time and have been settled in cash, funded by Silvercorp through Adventus.

Adventus intends to cause the Adventus Shares to be delisted from the TSX Venture Exchange as soon as practicable. In connection therewith, Adventus intends to submit an application to the applicable securities regulators to cease to be a reporting issuer and to terminate its public reporting obligations. Christian Kargl-Simard, Adventus' former President and Chief Executive Officer, and Frances Kwong, Adventus’ former Chief Financial Officer and Corporate

Secretary, have agreed to continue to provide services to Adventus in consultancy roles for a transition period following the completion of the Arrangement.
