Abacus Announces Further Increase to Financing

Press Release

Vancouver, BC – January 12, 2026. Further to the Abacus Mining & Exploration Corporation (“Abacus” or the “Company”) (TSXV: AME) news release dated December 8, 2025, announcing a non-brokered private placement (“Offering”) for proceeds of up to $300,000 through the issuance of up to 12,000,000 units (“Units”) at a price of $0.025 per Unit, the Company announced on January 6, 2026 that it had increased the size of the Offering to 13,850,000 Units for gross proceeds of up to $346,250.

The Company announces it is further increasing the size the Offering to 14,850,000 Units for gross proceeds of up to $371,250.

Each Unit will consist of one common share of the Company and one half of one non-transferable common share purchase warrant, with each warrant exercisable to purchase one common share of the Company at a price of $0.05 per common share for a period of 3 years from the date of closing of the Offering.

Proceeds from the Offering will be applied towards general working capital purposes. The Company holds a 20% interest carried to production in the advanced Ajax copper-gold development project in B.C. (see News Release dated December 1, 2025). In mid-2024 it acquired 100% of the Willow copper-molybdenum property, after exploring it for several years under an option, and it holds a lease on the adjacent Nev- Lorraine copper-molybdenum property both near Yerington, Nevada. Investors are referred to the Company website for the latest news and project descriptions.

The Offering is being conducted pursuant to available prospectus exemptions, including the exemption to existing shareholders of Abacus who are permitted to subscribe pursuant to British Columbia Instrument 45-534 – Exemption from Prospectus Requirement for Certain Trades to Existing Security Holders. If total subscriptions received for the Offering exceed the maximum Offering amount of $371,250, Units will be allocated pro rata among all subscribers qualifying under all available exemptions, unless the Company otherwise increases the maximum Offering amount.

Certain insiders of the Company may acquire securities under the Offering. Any such participation will be 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 Company expects that the Offering will be exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 as the Company is listed on the TSX Venture Exchange and neither the expected fair market value of securities being issued to related parties nor the consideration being paid by related parties would exceed 25% of the Company’s market capitalization. The Company will file a material change report in respect of the Offering. However, the material change report may be filed less than 21 days prior to the closing of the Offering, which is consistent with market practice and the Company deems reasonable in the circumstances.

The financing is subject to TSX Venture Exchange approval. In connection with the Offering, certain finders may receive a cash fee and/or non-transferable finder warrants. All securities issued will be subject to a four month hold period under Canadian securities law.

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 continues to work 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.
