Americore Resources Corp. Announces Closing of Initial Payments Under Primus Option Agreement

Vancouver, British Columbia--(Newsfile Corp. - December 15, 2025) - Americore Resources Corp. (TSXV: AMCO) (FSE: 5GP) (OTCQB: AMCOF) ("Americore" or the "Company") announces that it has completed the first two payments required under its option agreement with Primus Resources ("Primus") to acquire 42 unpatented lode mining claims contiguous with the Company's Trinity Silver Project in Pershing County, Nevada.

As disclosed in the Company's news release dated December 4, 2025, the Primus claims expand Americore's consolidated land position to approximately 22,700 acres (9,200 ha) and encompass all areas included in a 2012 historic resource estimate totaling 36 million ounces of silver equivalent (see Company release December 4, 2025).

Completion of Initial Payments

Americore confirms that it has now completed both early-stage payment obligations under the agreement:

• USD $8,900 on execution of the agreement (paid); and

• USD $25,000 and 100,000 common shares, issued and paid within five business days of filing with the TSX Venture Exchange.

Remaining commitments under the agreement remain unchanged:

• USD $40,000 cash and 150,000 shares on the first anniversary of the Effective Date;

• USD $60,000 cash and 250,000 units (one share and one warrant per unit) on the second anniversary;

• USD $230,000 cash and 500,000 units on the third anniversary.

Clarification of NSR Terms

Primus will retain a 2% NSR, of which 1% may be purchased by Americore for either:

• USD 2,000,000, or

• 38,000 ounces of silver

This corrects the 30,000-ounce reference in prior disclosure.

Project Significance

The Primus claims cover highly prospective structural and geochemical corridors flanking the historic Trinity open pit. Historic sampling returned values up to 1,690 g/t Ag and 4.33 g/t Au, and the land now controlled by Americore includes 364 historic drillholes previously held by Newmont (see Company release December 4, 2025).

The company confirms that this transaction was an arm's-length transaction, as defined under the policies of the TSX Venture Exchange and no finders' fees were paid.

Management Commentary

"Completing the first two payments under the Primus agreement underscores our commitment to rapidly advancing the Trinity Silver Project," stated Jeff Poloni, CEO. "The clarification of the NSR terms ensures our shareholders have clear and accurate information as we progress."
