The Trinity Silver Project

A District-Scale Silver Asset in Nevada

Trinity sits in one of Nevada’s most productive silver corridors — in the same county as Coeur Mining’s Rochester mine, which produced 15.4 million ounces of silver in 2025 following a major expansion.

Located in the Trinity Range of north-central Nevada, the project covers approximately 22,700 acres with both surface and mineral rights, and a historical silver resource of 36.1 million ounces identified from over 350 holes drilled by previous operators.

Accessible via maintained roads from Interstate 80, adjacent to the Union Pacific rail corridor

100% option on two fee simple sections (surface & mineral rights) plus 83 unpatented lode claims

Grid power and established water infrastructure in place

21-section lease position and 73 staked claims (~22,700 acres)

The position is structured with minimal upfront cash obligations and operator-friendly terms.

Trinity Silver Project Open Pit

The Trinity open pit, operated by U.S. Borax 1987–1989. Existing infrastructure reduces the development timeline and capital requirements for the next phase of work.

A Former Producer

Not a Grassroots Play

Trinity isn’t an untested exploration target — it’s a former producing mine with a known silver system.

In the late 1980s, U.S. Borax mined over one million tons of ore here, recovering approximately five million ounces of silver through heap leach. Operations ran September 1987 to August 1988, with processing continuing into 1989.

That work targeted the shallow oxide silver near surface. Below it sits unexplored sulphide mineralization — silver with lead and zinc — that makes up the majority of the historical resource and is Americore’s primary exploration target.

Existing pit infrastructure, road access, and operational history mean a lower starting cost and shorter timeline than any greenfield project.

Expanding the Project

The Best Holes Ended in Mineralization

Trinity’s silver system remains open at depth. Many historical holes were too shallow — Hole S-133 returned 105 ft @ 390.69 g/t Ag at the bottom of the hole. Hole S-113 intercepted 260 ft @ 149.69 g/t Ag, including a 55-foot interval at 455 g/t between 265–320 ft.

A cross-section confirms mineralization extends well below the depth of all existing drilling in both oxide and sulphide zones — a significant untested target and the primary driver for Americore’s upcoming drill program.

Exploration Roadmap

From Data to Drills to Definition

Americore is advancing Trinity through a phased program — from historical data to a modern, independently verified resource estimate.

Complete

Phase 1

Data Compilation & Target Generation

353-hole drill database compiled. AI-assisted geological analysis, airborne and hyperspectral surveys completed. Phase 2 permitting initiated.

Upcoming

Phase 2

Resource Expansion Drilling

Systematic drilling to confirm and expand the resource, test depth and along-strike extensions, and collect metallurgical samples. The value-inflection stage — where new data can meaningfully change the resource size and confidence level.

Follow-On

Phase 3

Economic Assessment

An updated Mineral Resource Estimate (MRE) followed by a Preliminary Economic Assessment (PEA) with metallurgical results, mine design, and current pricing — plus environmental baseline and development planning.

The data is there. The target is defined. The next step is drilling.
