Allegiant Gold Ltd. Announces Name Change and Rebranding to A2 Gold Corp.

Tonopah, Nevada / September 8, 2025 - Allegiant Gold Ltd. (“Allegiant” or the “Company”) (AUAU: TSX-V) (AUXXF: OTCQX) announces a name change and rebranding of the Company to A2 Gold Corp. reflecting the Company’s emergence as a leading gold explorer in the State of Nevada. The Company is embarking on a new and exciting chapter in the future development of its flagship Eastside project in the prolific Walker Lane trend following the raising of $14 million in equity capital over the past three months. The Company has delineated 1.4 million ounces of inferred gold resources and 8.8 million ounces of silver* so far and is targeting an increase in the near term through an aggressive, multi-phase drill program.

Peter Gianulis, CEO, commented, "We are driving forward a new era of growth for the Company. Our new name, A2 Gold, reflects this exciting chapter unfolding. With the recent closing of our $10.5 million financing, including a lead investment by Kinross Gold Corporation (“Kinross”), we are looking forward to commencing an 18,000 – 20,000 metre diamond core and RC drill program along with a large-scale geophysical and structural mapping initiative. Kinross is our cornerstone shareholder and strategic exploration partner, and the aim of the current campaign is to expand our existing resource and to target high grade extensions and new discovery zones.”

The name change to A2 Gold Corp. is underway and it is expected to take effect very soon following TSX Venture Exchange (“TSX-V”) approval. The Company will keep its existing ticker symbols, namely, “AUAU” on the TSX-V and “AUXXF” on the OTCQX. No action is required to be taken by shareholders with respect to the name change. Outstanding common share and warrant certificates bearing the old name of the Company are still valid and are not affected by the name change. The Company will publicly announce the definitive date for the name change once known.
