GIANT MINING ANNOUNCES UPSIZE OF AT-THE-MARKET OFFERING TO $15 MILLION

Giant Mining Corp. has entered into an amended and restated equity distribution agreement dated March 19, 2026, with Haywood Securities Inc., amending and restating the equity distribution agreement dated Sept. 29, 2025. Under the amended distribution agreement, the company will be entitled, at its discretion and from time to time during the term of the amended distribution agreement, to sell, through Haywood, as sole and exclusive placement agent, such number of common shares of the company having an aggregate gross sales price of up to $15-million, an increase of $10-million from the original agreement, which provided for the sale of up to $5-million of common shares. Sales of the common shares will be made through at-the-market distributions, as defined in National Instrument 44-102 (Shelf Distributions), directly on the Canadian Securities Exchange or, if any, other recognized Canadian marketplaces within the meaning of National Instrument 21-101 (Marketplace Operations) where the common shares are listed, quoted or otherwise traded. The volume and timing of distributions under the ATM offering, if any, will be determined in the company's sole discretion. The common shares will be distributed at market prices or prices related to prevailing market prices from time to time. As a result, prices of the common shares sold under the ATM offering will vary as between purchasers and during the period of distribution. The ATM offering will be effective until the earlier of the issuance and sale of all of the common shares issuable pursuant to the ATM offering and June 29, 2027, unless terminated prior to such date by the company or the agent in accordance with the terms of the amended distribution agreement. As of the date hereof, the company has distributed $4,994,178 of common shares pursuant to the ATM offering, and, in accordance with the terms of the amended distribution agreement, the company may distribute up to $10,055,822 of additional common shares.

Distributions of the common shares under the ATM offering will be made and qualified by way of a prospectus supplement dated Sept. 29, 2025, and amended and restated on March 19, 2026, to the company's existing short form base shelf prospectus dated May 29, 2025, as amended by amendment No. 1 dated March 17, 2026, which increased the dollar amount of securities that may be sold pursuant to the base shelf prospectus from $10-million to $20-million. The prospectus supplement has been filed with the securities commissions in all provinces and territories of Canada. The prospectus supplement (together with the related base shelf prospectus) is available on the SEDAR+ website maintained by the Canadian Securities Administrators. Alternatively, the company or Haywood will send the prospectus supplement (including the base shelf prospectus) upon request. Such requests may be made by sending an e-mail to Haywood at ecm@haywood.com.

The company intends to use the net proceeds of the ATM offering toward exploration expenses and a property payment for the Majuba Hill project, market awareness and administration expenses, consulting fees, potential acquisitions, legal and accounting fees, and general working capital purposes.
