Accompanying Documents
This notice is accompanied by the Information Circular, a form of proxy for registered shareholders or a voting instruction form for non-registered shareholders, and, for those registered shareholders who so requested, a copy of the audited consolidated financial statements and management’s discussion and analysis (“MD&A”) of the Company for the financial year ended December 31, 2025. Shareholders may request to receive copies of the Company’s annual and/or interim financial statements and MD&A on the form of proxy or voting instruction form. The audited consolidated financial statements and MD&A of the Company for the financial year ended December 31, 2025 will be sent to those shareholders who have previously requested to receive them. Otherwise, they are available upon request to the Company or they can be found on SEDAR+ at www.sedarplus.ca or on the Company’s website at www.goldgroupmining.com.
Plan of Arrangement
It is a condition to the implementation of the Plan of Arrangement that the Arrangement Resolution be approved at the Meeting. In addition, the Articles Resolution must be approved to allow the Company and Gold Resource to determine the ratio of the Consolidation following the Meeting and prior to the Effective Date, which ratio will also be subject to approval by the TSXV. Therefore, in order for the Plan of Arrangement to proceed as proposed, the Articles Resolution and the Arrangement Resolution must be approved by the affirmative vote of at least two-thirds (2/3) of the votes cast by shareholders present in person or represented by proxy and entitled to vote at the Meeting. Each shareholder is entitled to one vote for each Common Share held by such holder as of the close of business on the Record Date (as hereinafter defined).
| The Board of Directors unanimously recommends that shareholders vote FOR the Articles Resolution and FOR the Arrangement Resolution. |
Dissent Rights
The dissent rights of the shareholders are described in the Information Circular under the heading “The Arrangement – Dissent Rights” and are attached to the accompanying Information Circular as Appendix “I”. Shareholders should carefully read the section of the Information Circular entitled “The Arrangement – Dissent Rights” and consult with their advisors if they wish to exercise dissent rights, as any failure to fully comply with the dissent procedures described therein and the orders of the Supreme Court of British Columbia in respect of the Plan of Arrangement, may result in a loss of dissent rights.
Record Date
The board of directors of the Company has by resolution fixed the close of business on May 29, 2026 (the “Record Date”) as the record date, being the date for the determination of the holders of Common Shares entitled to receive notice of and to vote at the Meeting and any adjournment thereof. Goldgroup shareholders are requested to complete and return the enclosed form of proxy to ensure that your Common Shares will be represented at the Meeting, whether or not you are personally able to attend. If you have questions, you may contact the Company’s Chief Financial Officer and Corporate Secretary, Anthony Balic, by telephone at 604-682-1943 or by email at abalic@goldgroupmining.com.
