Abacus Acquires 100% of the Willow Porphyry Copper Property

Vancouver, BC – June 6, 2024. Abacus Mining & Exploration Corporation (“Abacus” or “The

Company”) (TSXV:AME) is pleased to announce that it has signed an 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”).

Under the terms of the Agreement, which is subject to TSX Venture Exchange (“TSX -V”)

approval, Abacus will issue common shares of Abacus (“Shares”) to Almadex, as to:

• 7,500,000 shares in the capital of the Company (“ Shares”) (the “Initial Shares”) on

closing of the transaction, expected to be on or about June 30, 2024 (the “Closing

Date”); and,

• on July 31, 2025 (the “Top -Up Date”), such number of Shares owned by Almadex

immediately following the completion of the transaction on the Closing Date , then

divided by the number of Shares outstanding on the Top -Up Date, equals 0.08,

rounded down to the nearest whole Share (the “Top-Up Shares”).

Title to the claims comprising the Willow Property will be transferred to Abacus on issuance

of the Initial Shares, and Abacus will, as soon as reasonably practicable following the Closing

Date and in any event no later than December 31, 2025, complete the drilling of a minimum

600 metre exploratory hole on the Willow Property within an area agreed upon with Almadex.

The Willow Property is subject to a 2% NSR from future production of minerals from the Willow

Property.

“An option agreement on Willow was signed in early 2017 between Abacus and Almadex.,

allowing Abacus to earn an aggregate 75% interest in Willow by meeting certain spending

thresholds and by issuing shares ” commented Paul G. Anderson, President and CEO of

Abacus. “This Agreement removes the spending commitments, and it consolidates

ownership of a very prospective porphyry copper property which remains poorly drill tested.”

Abacus completed geological, geochemical and geophysical work on Willow beginning in

2017, identifying an extensive zone of intense silicic and advanced argillic alteration, marked

by coincident geological, geochemical and geophysical signatures typical of a porphyry Cu-

Mo deposit.

The Company drilled two diamond drill holes in 2018, which intersected the Luhr Hill granite,

which is the host rock of the four known porphyry copper -molybdenum (Cu-Mo) deposits in

the Yerington camp. The holes hit short intervals of copper in the 0.1 to 0.2% range with

elevated Mo.

In 2021, three additional core holes intersected broader intervals of the Luhr Hill granite with

significant composited intervals of low -grade copper and molybdenum mineralization. The

results indicate close proximity to a porphyry copper center and clearly indicate that further

drilling is warranted.

Cu-Mo porphyry deposits at Yerington occur at the contact of the Luhr Hill granite porphyry

and surrounding volcanic rocks, or else close to the granite but associated with porphyry dyke

swarms further into the volcanic package. As there are no known insta nces of this granite in

the camp without an associated porphyry, the discovery of Luhr Hill granite on Willow marks a

key new discovery, which means that there is a very high likelihood of a Cu-Mo deposit being

found on Willow.

The Company’s target is essentially identical to the two largest porphyry deposits in the

Yerington camp, namely the past-producing Yerington mine and the undeveloped Ann Mason

deposit. Because the target at Willow is covered by later volcanism, prospectin g by drill and

sampling for geochemistry is the only effective means of trying to locate a porphyry center,

and this often takes several drill campaigns to achieve, with each successive campaign

vectoring closer to a porphyry center.

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 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 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 is in the process of acquiring a 100% interest in the Willow copper-gold property located near Yerington,

Nevada, and it also controls the contiguous Nev-Lorraine claims subject to a ten-year lease agreement.
