1510993 B.C. LTD. FILES AMENDED EARLY WARNING REPORT IN RESPECT OF ALLEGIANCE RESOURCES CORP.

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Vernon, British Columbia - November 3, 2026 - 1510993 B.C. Ltd. (the "Acquiror"), a company wholly-owned by Amardeep Singh Purewal, announces that it has filed an amended early warning report to correct the early warning reports and news releases filed by the Acquiror on October 23, 2026 and October 26, 2026 (the "Prior Disclosure") in respect of common shares ("Common Shares") of Allegiance Resources Corp. (formerly Pegmatite One Lithium and Gold Corp.) (the "Issuer"), whose Common Shares trade on the Canadian Securities Exchange under the symbol "ALLG".

The Prior Disclosure did not include 65,087 Common Shares held by Mr. Purewal through his registered retirement savings plan, his locked-in retirement account and A Purewal Developments & Consulting Ltd., a company controlled by Mr. Purewal (together with Mr. Purewal, the "Joint Actors"), and incorrectly reported certain transactions and holdings. The corrected information is set out below.

On June 26, 2026, the Acquiror acquired 925,925 units of the Issuer at a price of $0.135 per unit in a non-brokered private placement. Each unit consists of one Common Share and one Common Share purchase warrant (a "Warrant"), with each Warrant exercisable to acquire one Common Share at a price of $0.20 until June 26, 2028. Immediately after the private placement, the Acquiror and the Joint Actors held 1,479,247 Common Shares and 925,925 Warrants, representing approximately 11.39% of the 12,985,390 Common Shares then outstanding on a non-diluted basis and approximately 17.29% on a partially diluted basis, and not 1,414,250 Common Shares (approximately 10.89% and 16.82%) as previously reported.

Between June 27, 2026 and October 21, 2026, the Acquiror acquired a net 337,118 Common Shares, including 294,118 Common Shares acquired by private agreement at a price of $0.10 per Common Share, and Mr. Purewal acquired 20,500 Common Shares directly, and not 352,528 Common Shares and 21,000 Common Shares, respectively, as previously reported. The September 16, 2026 private purchase increased the holdings of the Acquiror and the Joint Actors from 1,548,747 Common Shares (approximately 11.34% on a non-diluted basis and 16.98% on a partially diluted basis) to 1,842,865 Common Shares (approximately 13.50% and 18.99%), based on 13,652,057 Common Shares outstanding.

On October 22, 2026, the Acquiror sold 825,353 Common Shares in the open market for gross proceeds of $71,651.67, being an average price of approximately $0.0868 per Common Share, and not 422,779 Common Shares as previously reported. Immediately before the sale, the Acquiror and the Joint Actors held 1,836,865 Common Shares and 925,925 Warrants, representing approximately 13.45% of the 13,652,057 Common Shares outstanding on a non-diluted basis and approximately 18.95% on a partially diluted basis. Immediately after the sale, they held 1,011,512 Common Shares and 925,925 Warrants, representing approximately 7.41% on a non-diluted basis and approximately 13.29% on a partially diluted basis.

Between October 27, 2026 and October 29, 2026, the Acquiror and Mr. Purewal sold a further 115,500 Common Shares in the open market. The Acquiror and the Joint Actors currently hold 896,012 Common Shares and 925,925 Warrants, representing approximately 6.56% of the 13,652,057 Common Shares outstanding on a non-diluted basis and approximately 12.50% on a partially diluted basis, assuming the exercise of the Warrants only. The Acquiror is also a party to an asset purchase agreement with the Issuer dated September 27, 2026, under which it is entitled to receive 225,000 Common Shares on closing, expected on or about November 5, 2026. Following closing, and assuming no other changes, the Acquiror and the Joint Actors are expected to hold approximately 7.55% of the outstanding Common Shares on a non-diluted basis and approximately 12.97% on a partially diluted basis.

The Prior Disclosure stated that the Acquiror and Mr. Purewal had ceased to be insiders of the Issuer. That statement was incorrect. Mr. Purewal has beneficial ownership of, or control or direction over, directly or indirectly, securities of the Issuer carrying more than 10% of the voting rights attached to all of the Issuer's outstanding voting securities on a post-conversion basis. As a result, Mr. Purewal is a "significant shareholder based on post-conversion beneficial ownership" and remains a "reporting insider" of the Issuer, as those terms are defined in section 1.1 of National Instrument 55-104 - Insider Reporting Requirements and Exemptions.

The Acquiror and the Joint Actors hold the securities of the Issuer for investment purposes and may, depending on market conditions and other factors they consider relevant, increase or decrease their ownership of, or control or direction over, securities of the Issuer through market transactions, private agreements, exercises of the Warrants or otherwise.

This news release is being issued pursuant to the requirements of National Instrument 62-103 - The Early Warning System and Related Take-Over Bid and Insider Reporting Issues, which requires a report to be filed on SEDAR+ (www.sedarplus.ca) containing additional information with respect to the foregoing matters. A copy of the amended early warning report to which this news release relates will be available on the Issuer's SEDAR+ profile at www.sedarplus.ca.

The head office of the Issuer is located at 3606 - 833 Seymour Street, Vancouver, BC V6B 0G4. The address of the Acquiror is 7133 Nakiska Drive, Vernon, BC V1B 3M5.
