Athabasca Minerals Provides Update on Annual Filings

Calgary, May 1, 2023 - Athabasca Minerals Inc. (TSXV: AMI) ("AMI") announced today that it will not be filing its annual financial statements, accompanying management's discussion and analysis and related chief executive officer and chief financial officer certifications for the financial year ended December 31, 2022 (collectively, the "Annual Filings"), within the period prescribed for the filing of such documents under Parts 4, 5 and 6 of National Instrument 51- 102 Continuous Disclosure Obligations and pursuant to National Instrument 52-109 Certification of Disclosure in Issuers' Annual and Interim Filings, namely within 120 days of year-end, being May 01, 2023 (the "Filing Deadline").

Due to the complexity of auditing work related to the strategic acquisition, and significant operational growth, of a U.S. sand mine and facilities in Wisconsin by AMI Silica LLC, as well as the corporate restructuring and management changes in 2022 AMI was not able to finalize the Annual Filings by the Filing Deadline. AMI's audit remains ongoing at this time. AMI is working closely with its auditor and is making every effort to file the Annual Filings in a timely fashion and expects to file the Annual Filings on or about May 12, 2023.
