## Exhibit 99.1

**Exhibit 99.1**

**Black Hawk Acquisition Corporation Amends Its Definitive Proxy Statement**

DANVILLE, Calif., June 20, 2025 (GLOBE NEWSWIRE) -- Black Hawk Acquisition Corporation (NASDAQ: BKHAU, the "Company") announced today that it filed a supplement to its definitive proxy statement, originally file with the Securities and Exchange Commission on June 10, 2025, to amend the language of the Trust Amendment Proposal. Specifically, the amendment removes the words "up to $55,000 per one-month extension". As revised, the Trust Amendment Proposal provides that the Company will deposit in to the trust account an amount equal to $0.033 multiplied by the number of ordinary shares sold to the public in the Company's initial public offering and that remain outstanding after giving effect to the shares that are redeemed in connection with the vote on the Trust Amendment Proposal, for each one-month extension of the deadline to consummate an initial business combination.

This change eliminates the Company's discretion to deposit a lesser amount and ensures greater clarity and consistency regarding the extension fee obligation.
