ADEX MINING ADOPTS SEMI-ANNUAL REPORTING

Toronto, Ontario May 1st, 2026 Adex Mining Inc. ("Adex" or the "Company") (TSX-V: ADE) is pleased to announce its intention to participate in the semi-annual financial reporting framework pilot program recently adopted by the Canadian Securities Administrators. This news release is being filed pursuant to Coordinated Blanket Order 51-933 Exemptions to Permit Semi-Annual Reporting for Certain Venture Issuers ("Blanket Order").

The Blanket Order allows eligible venture issuers listed on the TSX Venture Exchange to voluntarily move from a quarterly to a semi-annual financial reporting framework.

Adex's fiscal year end is December 31. Under the Blanket Order, the Company will be exempt from filing interim financial reports and related Management Discussion & Analysis ("MD&As") for its first and third quarters.

dot Initial interim Period: The Company will not file an interim financial report or interim MD&A for the first quarter of 2026 ending March 31, 2026 and the third quarter of 2026 ending September 30, 2026; and

dot Ongoing Reporting: The Company will continue to file audited annual financial statements (due within 120 days of year-end) and six-month interim financial reports (due within 60 days of June 30).

The Company confirms that it meets the eligibility criteria to rely on the Blanket Order, which includes being a venture issuer with annual revenues of less than $10 million, having a disclosure record of over 12 months and having filed all required periodic and timely continuous disclosure documents.

The Company believes that adopting semi-annual reporting will reduce the administrative and financial burden associated with quarterly reporting, which is the objective of the Blanket Order. The Company expects that the reduced reporting requirements will allow management to devote additional time and financial resources toward maximizing value for shareholders.
