Urgent need for change

Canex is Gold Basin's largest and controlling shareholder, holding control over 54.04 per cent of the shares of Gold Basin following the success of the company's successful tender offer. Despite Canex's position reflecting the clear will of the majority of Gold Basin shares, Gold Basin management has refused to facilitate an orderly transition of leadership, and as a result, the Supreme Court of British Columbia has ordered the meeting take place.

Gold Basin has been in crisis for the past year. Instead of a capable board working to create value for shareholders, the board has been directly responsible for diminishing and paralyzing shareholders' investment in Gold Basin, showing a flagrant disregard for securities laws, continuous disclosure obligations and basic corporate governance principles. At every step of the way over the past year, the board has acted not to protect shareholders or remedy deficiencies, but to obstruct, entrench and encumber, frequently through related party transactions. The reasons for the urgency of making a change to the board are stark:

• No liquidity. On May 6, 2025, the British Columbia Securities Commission imposed a cease trade order against the company's shares. The next day, the Canadian Investment Regulatory Organization imposed a halt in trading of the company's shares on the TSX Venture Exchange. The board has yet to provide shareholders with any estimate of when a revocation of the cease trade order and the halt can be expected, if at all.
• Massive value destruction. The company generated negative total shareholder returns of negative 43.75 per cent in the year prior to the cease trade order. During the same time period, the MVIS Global Junior gold Miners Index (MVGDXJ) had a total return of 58.54 per cent. Since the cease trade order, the company's shareholders have not benefitted from a remarkable bull run for gold, where the MVGDXJ has returned a further 117.38 per cent while Gold Basin shareholders have been left on the sidelines.
• No financial statements. The company has not filed financial statements for any period since September, 2024 -- 16 months ago -- in contravention of securities laws.
• Disenfranchisement of shareholders' voting rights. The company has not held an annual general meeting of shareholders for 20 months, in breach of corporate law requirements. The board lacks any mandate from shareholders.
• Failure to file corporate reports. The company is not in good standing with British Columbia Registry Services, as no annual report has been filed since Nov. 24, 2022. Under the Business Corporations Act (British Columbia), if a company fails to file its annual reports or other required documents for two consecutive years it may be struck by the registrar of companies, dissolved and cease existence as a corporation.
• No auditor. The company's auditor, Manning Elliott LLP, resigned on June 28, 2025. Seven months later, no successor firm has been named.
• No transfer agent. The company's transfer agent, TSX Trust Company, resigned on Aug. 21, 2025. On Feb. 2, 2026, in response to a petition by Canex, the court ordered that TSX Trust Company be reinstated as Gold Basin's transfer agent and registrar in connection with the Canex bid.
• No CFO. Chief financial officer Stephen Pearce resigned on Sept. 25, 2025. Despite a TSX-V requirement that listed issuers must have a CFO, four months later the company has not named a successor.
• No corporate secretary. Mr. Pearce was also acting as corporate secretary at the time of his resignation. Despite a TSX-V requirement that listed issuers must have a corporate secretary, four months later the company has not named a successor.
• Conveyance of only mineral asset to a related party. On April 28, 2025, the company announced that it had executed a binding farm-in agreement (the Helix farm-in agreement) granting a related party, Helix Resources Ltd., the right to earn up to 40 per cent of its sole mineral property, the Gold Basin project, and acquire a 1-per-cent net smelter royalty over the Gold Basin project in consideration for the issuance of 150 million Helix shares. The company provided no evidence to shareholders that the consideration offered in the Helix transaction is fair or reasonable, failed to publicly disclose the related party nature of the Helix transaction, failed to file a material change report in respect of the Helix transaction or a copy of the Helix farm-in agreement as required under securities law, and did not obtain required TSX-V approval of the Helix transaction.
• Encumbrance of only mineral asset by a related party. On Jan. 19, 2026, the company announced the updated terms of an unsecured loan in the amount of $500,000 (U.S.) received from a related party, Charrua Capital LLC. Under the updated terms of the loan, a portion of the Gold Basin project has been put up as security. The company has announced no plan for repaying the stated amount of approximately $856,730 ($617,652 (U.S.)) owing on the loan, which is due March 31, 2026. The company failed to publicly disclose the related party nature of the loan or the update, failed to file a material change report in respect of the loan or the update or a copy of the loan or update documents as required under securities law, and did not obtain required TSX-V approval of the loan or update. Further, the loan update was a transparently improper defensive tactic, in violation of securities policies, as it was announced on Jan. 19, 2026, when the Canex bid was scheduled to expire and which the board knew had over 47-per-cent support and was likely to succeed.
• Litigation. The company has been named as a defendant in a lawsuit commenced by Harris Exploration Drilling & Associates in respect of a claim for outstanding payments of $285,193 (U.S.). The company's former chief financial officer, corporate secretary and a former director, Mark Lotz, has filed a notice of civil claim against the company for breach of a debt settlement agreement relating to $62,757.53 for unpaid directors fees. The company's auditor, Manning Elliott LLP, filed a notice of civil claim against the company for unpaid fees for accounting services of $77,065.14.
