Americore Resources Corp. Significantly

Expands Land Position at the Trinity Silver

Project, Historic Resource Base Tripled to 36

Million oz Silver Equivalent

Vancouver, British Columbia--(Newsfile Corp. - December 4, 2025) - Americore Resources Corp.

(TSXV: AMCO) (FSE: 5GP) (OTCQB: AMCOF) ("Americore" or the "Company") announces a strategic

expansion of its land position at the Trinity Silver Project in Pershing County, Nevada through an option

agreement with Primus Resources to acquire 42 unpatented lode mining claims. These claims are

directly contiguous with Americore's core project holdings, increasing the consolidated project footprint

to approximately 22,700 acres (9,200 ha).

Grab samples taken on the newly acquired claims include

silver contents up to 1690 g/t Ag and 4.33 g/t Au.

This additional land now covers all of the areas

included in an historic resource estimate made in 2012, increasing the company's historic resource

base to over 36 million ounces of silver equivalent.

Strategic Importance of the Primus Claims

The new claims are positioned both northeast and south of the historically mined Trinity open pit,

including five HiHo claims situated immediately northeast of the pit and 37 TS and ELM claims

extending southward across favourable structural and geochemical ground. With this acquisition,

Americore now controls all ground hosting the 364 historic drillholes in the database acquired from

Newmont.

Additionally, the Company now controls all of the land included in an historic resources estimate

prepared for Liberty Silver in 2012 (Updated Technical Report on Resources Trinity Silver Project,

Pershing County, Nevada, prepared by SRK Consulting (U.S.) Inc, with an effective date of December

20, 2012).

This report was filed on SEDAR under the profile of Liberty Silver Corp.

The report estimates

an Inferred Mineral Resource of 26.22 million tons averaging 1.07 oz/ton (36.7 g/t) Ag

for a metal content

of 28.5 million ounces of silver, or 36 million ounce silver equivalent.

This represents a threefold increase

in the historic resource base (see Company news release November 24, 2025).

The following assumptions were used to calculate silver equivalent (AgEq):

Three-year trailing Ag, Pb and Zn prices of US$28.41/oz, US$1.02/lb and US$0.96/lb respectively;

Sulphide metallurgical recoveries of 85.8% Ag, 85.4% Pb and 82.8% Zn;

Mining and processing cost of US$10.55/ton;

A 4% NSR royalty was applied.

These estimates are considered to be historic in nature.

The Company is not treating these historic

estimates as a current resource.

The Qualified Person has not done sufficient work to classify the

estimates as a current resource and there is no guarantee that further work will convert these historical

estimates to current resources.

Geological Highlights

Silver mineralization at Trinity is primarily hosted within rhyolitic tuffs, volcaniclastic units, intrusive rocks,

and structurally controlled breccias, with both oxide and sulphide domains present. The TS and ELM

claims exhibit multi-metal anomalies consistent with the Trinity system.

Technical Context & NI 43-101 Support

The 2025 NI 43-101 report prepared by RESPEC (Technical Report on the Trinity Project, Pershing

County, NV, authored by J Bickel, RESPEC, Reno NV, dated October 28, 2025, and filed on SEDAR

under the company's profile) notes that silver-lead-zinc-copper zonation is permissive of additional

mineralization east, southeast, and northeast of previously drilled areas. The Primus claims lie directly

within these open extensions.

The vendor collected a total of seven chip and grab from these sites over a N-S strike length of 400 feet..

Several samples were highly anomalous in the metals found at the Trinity mine (Ag, Pb and Zn) but also

include a possible second mineralizing event which may have introduced an additional suites of mineral

including Au.

Project Background

The Trinity Silver Project benefits from strong infrastructure and historic mining, with U.S. Borax

producing approximately 5 million ounces of silver between 1987–1988. These results are historical and

should not be relied upon for current economic assessment.
