AME Abacus Mining and Exploration Corporation

Abacus Mining & Exploration Corporation (“Abacus” or “The Company”) (TSXV:AME) announces that further to its news release dated June 4, 2024, it has amended, at the request of the TSX-Venture Exchange (the “Exchange”), certain terms of the June 4, 2024 agreement (the “June 4, 2024 Agreement”) with Almadex Minerals Ltd. and its wholly-owned Nevada subsidiary Almadex America Inc. (“Almadex”), to acquire a 100% ownership interest in the Willow porphyry copper property located in Yerington, Nevada, (“Willow Property”) and data associated with the Willow Property (the “Willow Data”) (the “Amending Agreement”).

Pursuant to the terms of the Amending Agreement:

• the Company has issued 9,546,922 common shares of Abacus to Almadex
• the requirement, under the June 4, 2024 Agreement to issue the Top-Up Shares to Almadex on July 31, 2025, has been removed
• the NSR has been increased from 2.0% from future production of minerals from the Willow Property under the June 4, 2024 Agreement, to 2.5%, of which the Company can buy back 0.5% for $500,000 for a period of 2 years from the Closing date, which consideration may be paid, at the Company’s election, either in cash or, subject to prior Exchange approval at the time of election, equivalent shares in the capital of the Company.

“The revised Agreement has the effect of immediately fixing the number of shares to be issued to Almadex” commented Paul G. Anderson, President and CEO of Abacus. “The Company has now consolidated ownership of a very prospective porphyry copper property in a very active district, which remains poorly drill tested.”

Work done to date by Abacus leads the company to believe that Willow contains a fifth porphyry within the Yerington camp. Of the known porphyries in the camp, the Ann Mason deposit lies adjacent and east of Willow and is held by HudBay Minerals. In 2021, Hudbay announced an updated PEA on Ann Mason with a revised M&I resource of 2.2 billion tonnes at 0.34% Cu. *

Lion Copper and Gold control the Yerington, Bear and MacArthur porphyries adjacent and to the east of Ann Mason. Anaconda mined the Yerington porphyry between 1952 until 1978, producing 1.6 billion pounds of copper. MacArthur (M&I of 159MT at 0.212% Cu) has seen some past production and is currently undergoing a Prefeasibility Study. In March of 2022, Lion announced that Rio Tinto had taken an option on the company’s Yerington assets, and it announced the results of a new PEA in March of this year. *

The Company in addition to Willow has a lease on the Nev-Lorraine claims contiguous to Willow, giving it the right to explore and to elect to purchase these claims outright over a ten-year period.

Abacus also holds a 20% ownership interest in the Ajax copper-gold porphyry project, located near Kamloops, British Columbia., which is managed by base metal major KGHM Polska Miedź S.A., who hold the remaining 80%. The Ajax Project contains significant quantities of copper and gold, within a NI 43-101 Proven and Probable Mineral Reserve of 426 Mt at 0.29% Cu, 0.19 g/t Au and 0.39 g/t Ag. Contained metal is in the order of 2.7 Bil lbs Cu, 2.6 Moz Au and 5.3 Moz Ag**.

About AbacusAbacus is a mineral exploration and mine development company currently focused on copper and gold in B.C. and Nevada. The Company’s main asset is a 20% ownership interest, together with KGHM Polska Miedź S.A. (80%), in the proposed copper-gold Ajax Mine located southwest of Kamloops, B.C., which has undergone a joint provincial and federal environmental assessment process. On December 14, 2017, a decision was made by the B.C. Minister of Environment and Climate Change Strategy and the Minister of Energy, Mines and Petroleum Resources to decline to issue an environmental assessment certificate for the Project. KGHM have recently reopened an office in Kamloops, B.C. to facilitate First Nation, community and governmental engagement in order to advance the project towards a potential resubmission of the environmental application.

Abacus also owns a 100% interest in the Willow copper-gold property located near Yerington, Nevada, and it controls the contiguous Nev-Lorraine claims subject to a ten-year lease agreement.
