Abacus Completes Its Non-Brokered Private Placement

Press Release

Vancouver, BC – January 19, 2026. Abacus Mining & Exploration Corporation (“Abacus” or the “Company”) (TSXV: AME) is pleased to announce the closing of its non-brokered private placement of units (the “Private Placement”), as announced on December 8, 2025, January 6, 2026 and January 12, 2026, pursuant to which the Company raised total gross proceed of $371,250, and issued 14,850,000 units (“Units”) at a price of $0.025 per Unit. Each Unit consists of one common share of the Company (a “Share”) and one-half of one common share purchase warrant (a “Warrant”), with each full Warrant exercisable to purchase one Share at a price of $0.05 per Share until January 19, 2029.

All securities issued in connection with the Private Placement are subject to a statutory four month hold period expiring May 20, 2026, and the Private Placement is subject to final acceptance by the TSX Venture Exchange (the “TSXV”).

The Private Placement was offered to existing shareholders of Abacus who were permitted to subscribe pursuant to British Columbia Instrument 45-534 – Exemption from Prospectus Requirements for Certain Trades to Existing Security Holders, as well as under other available prospectus exemptions.

Proceeds from the Private Placement will be applied towards the Company’s general working capital.

The Company has a 100% interest in the Willow copper-molybdenum property, and it holds a lease on the adjacent Nev-Lorraine copper-molybdenum property near Yerington, Nevada, as well as a 20% interest carried to production in the advanced Ajax copper-gold development project in B.C. Investors are referred to the Company website for the latest news and project descriptions.

Certain insiders of the Company have acquired securities under the Private Placement. Any such participation is considered to be a “related party transaction” as defined under Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“MI 61-101”). The Private Placement is exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 as the Company is listed on the TSXV and neither the fair market value of securities issued to related parties nor the consideration paid by related parties exceeds 25% of the Company’s market capitalization. The Company will file a material change report in respect of the Private Placement. However, the material change report may be filed less than 21 days prior to the closing of the Private Placement, which is consistent with market practice and the Company deems reasonable in the circumstances.

This news release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the United States. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the “1933 Act”), or any state securities laws and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons (as defined in Regulation S under the 1933 Act) absent such registration or an applicable exemption from such registration requirements.

About Abacus

Abacus 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.
