Americore Resources Corp. Significantly Expands Land Position at the Trinity Silver Project, Historic Resource Base Tripled to 36 Million oz Silver Equivalent
Rhea-AI Summary
Americore Resources (OTCQB: AMCOF) expanded the Trinity Silver Project footprint to ~22,700 acres by optioning 42 unpatented claims from Primus, consolidating ground that hosts 364 historic drillholes and all areas in a 2012 historic resource.
The combined historic estimate equals >36 million ounces silver equivalent (Inferred: 26.22 million tons at 1.07 oz/ton Ag). Grab samples on new claims returned values up to 1,690 g/t Ag and 4.33 g/t Au. Company targets a current NI 43-101 resource in Q2 2026 and plans digitization, AI 3D modelling, and confirmation drilling.

Historical Context
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| Dec 04 | Land/resource expansion | Positive | +26.9% | Optioned 42 claims, consolidating Trinity and tripling historic resource base. |
| Dec 01 | Project update | Positive | +27.1% | Expanded land by ~1,400 acres and outlined path to NI 43-101 resource. |
Recent Trinity Silver news items were followed by strong double-digit gains, suggesting past sensitivity to project expansion updates.
Over late Nov–Dec 2025, Americore issued two Trinity Silver Project updates expanding its land position and advancing toward a NI 43-101 resource by Q2 2026. On Dec 1, 2025, a land expansion of ~1,400 acres and detailed workplan saw a 27.14% move. On Dec 4, 2025, today’s release tripled historic silver-equivalent resources to over 36M oz and coincided with a 26.95% move, underscoring prior strong reactions to Trinity progress.
Market Pulse Summary
The stock surged +26.9% in the session following this news. A strong positive reaction aligns with prior Trinity Silver updates, where news on land consolidation and historic resource expansion led to moves of 26.95% and 27.14%. The tripling of the historic silver-equivalent base to over 36M oz and clear exploration milestones support enthusiasm. However, the estimates remain historic and non-current, and the option terms plus future drilling and NI 43-101 work introduce ongoing execution risk that could temper sustainability.

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).
| Cut-off grade Ag oz/ton | Resource category | Mineralization type | Million Tons | oz/ton Ag | Contained Ag (oz) | |||
| 0.5 | Inferred | Oxide | 6.43 | 1.134 | 7,287,000 | |||
| Cut-off grade AgEq oz/ton | Resource category | Mineralization type | Tons | oz/ton Ag | Contained Ag (oz) | %Pb | %Zn | Contained AgEq (oz) | ||||
| 0.8 | Inferred | Sulphide | 19.79 | 1.07 | 21,165,000 | 0.217 | 0.354 | 28,836,759 | ||||
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 and82.8% 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. Analytical results are shown in the table below.
| Sample # | Ag | Pb | Zn | Au | Sn | Sb | Mo | Hg | Cu | As |
| g/t | ppm | ppm | g/t | ppm | ppm | ppm | ppm | ppm | ppm | |

| E569473 | 408 | 1.25 | 226 | 4380 | 10.45 | 3.99 | 954 | >10000 |
It should be noted that grab sample results are not indicative of the presence of economic mineralization.
