BONANZA MINING CORPORATION ANNOUNCES THE CLOSING OF TWO MINERAL PROPERTY PURCHASE AND SALE AGREEMENTS

March 30, 2026 - Vancouver, British Columbia: Bonanza Mining Corporation ("Bonanza" or the "Company") (TSX-V: BNZ) announces that it has closed the two Mineral Property Purchase and Sale Agreements as originally announced on January 5, 2026. These Agreements replace two Option Agreements originally negotiated in 2018, each as subsequently amended.

The first such Agreement is with Christopher Graf, a director of the Company, and is in respect of 5 zinc-lead-silver mineral claims known as the Shag property located in the Golden Mining District of British Columbia in the southern Rockies approximately 24 km northeast of the town of Canal Flats and 35 km east of Radium Hot Springs. Pursuant to this Agreement, the Company issued 666,667 post-consolidated common shares to Mr. Graf, who has also had reserved in his favour a 3% net smelter return royalty on minerals produced from the property.

The second such Agreement is with Christopher Graf and with Theodore Muraro, an individual who deals with the Company on an arm's-length basis, and is in respect of 8 zinc-lead-silver-copper mineral claims known as the Frog property located in the Liard Mining District of British Columbia approximately 170 km east of Imperial Metals - Newmont's Red Chris mine near Dease Lake, British Columbia and about 70 km east of the major Kutcho Creek copper-zinc massive sulphide project that is being developed by Capstone Mining Corp.'s subsidiary Kutcho Copper Corp. Pursuant to this Agreement, the Company issued a total of 733,334 post-consolidated common shares to Mr. Graf and Mr. Muraro, each as to 50%; they also have had reserved in their favour a 3% net smelter return royalty on minerals produced from the property.

As Christopher Graf is a non-arm's length party to Bonanza, Bonanza is relying on the exemption from the formal valuation requirement contained in section 5.5 of Multilateral Instrument 61-101 "Protection of Minority Security Holders in Special Transactions", and on the exemption from the minority shareholder approval requirement contained in section 5.7 of said Multilateral Instrument 61-101.

All shares issued pursuant to these Agreements are subject to a hold period until July 31, 2026. There were no finders' fees paid in respect of either of these Agreements.
