A 22,700-acre district-scale silver project in Nevada with a historical resource of 36.1 million ounces silver equivalent, a 782,800-ounce silver stockpile ready for processing, and a clear path to resource expansion drilling.
Located in Pershing County, Nevada, approximately 17 miles north-northwest of Lovelock. Accessible by maintained roads from Interstate 80, with proximity to the Union Pacific rail corridor, grid power, and established water infrastructure.
Americore holds options on 100% of two fee simple sections (surface and mineral rights) and 83 unpatented lode mining claims, plus a lease position spanning 21 sections. An additional 73 staked claims bring the total land package to approximately 22,700 acres.
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. Results at adjacent properties are not necessarily indicative of results on the Trinity property.

Trinity is a former producer. US Borax mined silver here in the late 1980s when prices were below US$7/oz, demonstrating the presence of significant silver mineralization. That track record, plus a 353-hole drill database, gives Americore a head start most explorers don’t have.
US Borax and Santa Fe Pacific Minerals explored the Trinity Range with extensive drilling, identifying a structurally controlled silver-lead-zinc system hosted in rhyolite.
US Borax and a joint venture partner operated an open-pit heap leach mine, mining 1,085,790 tons at an average grade of 6.32 oz/t silver and recovering approximately 5 million ounces of silver. Operations were suspended due to low silver prices — a result of market conditions at the time, not a reflection of deposit geology.
Processing terminated. A stockpile of 428,634 tons containing an estimated 782,769 ounces of silver was left on surface. It remains on the property as a potential future processing consideration, subject to additional metallurgical study and economic analysis.
AuEx Ventures conducted modern exploration including a 20-hole RC drill program. In 2012, SRK Consulting prepared an NI 43-101 inferred resource estimate of 36.1 Moz silver equivalent.
Newmont fulfilled all closure obligations. Nevada released the reclamation bond — no legacy environmental liabilities remain.
Americore assembled the 22,700-acre land package, completed Phase 1 data compilation with AI-assisted geological analysis, and is now permitting a Phase 2 drill program.
Silver mineralization at Trinity is controlled by a network of deep fault zones that channelled metal-bearing fluids through porous volcanic rock (rhyolite), concentrating silver into predictable, drillable corridors. The system’s alteration footprint extends 1.6 miles beyond the main mineralized area — far larger than the area drilled to date.
More recent studies have re-interpreted Trinity as an orogenic system — a deeper, more extensive style of deposit than originally modelled. The deposit remains open at depth and along strike, meaning drilling has not yet found the edges. SRK identified five fault corridors in the resource model, each a defined drilling target. The existing open pit sits on the strongest — the Trinity Fault zone — while peripheral zones remain underexplored.
The deposit has two layers: a shallow oxide zone where silver can be extracted cheaply through heap leaching, and a deeper sulfide zone containing silver, lead, and zinc that would require conventional milling. Two distinct mineralization styles, each with different processing considerations.
Now understood as an orogenic system — deeper and more extensive than the original open-pit heap leach model. Open at depth and along strike, with structurally controlled geometry interpreted to be consistent and amenable to systematic drilling.
Rhyolite porphyry, aphanitic rhyolite, and volcaniclastic rocks. Alteration halo extends 1.6 miles beyond the main mineralized area.
Five fault corridors mapped by SRK. Geophysical entropy analysis has identified zones of structural complexity with high prospectivity beyond the current resource.
Oxide: silver-dominant, heap-leachable, lower cost. Sulfide: polymetallic, higher value per tonne, requires flotation.
Open at depth and along strike. Drill spacing widens from 100 ft in the core zone to 350 ft at the margins — significant room to grow.
Estimated by SRK Consulting (U.S.) Inc., effective December 18, 2012, in compliance with NI 43-101 standards. Based on 353 drill holes totaling 159,261 feet. All material classified as Inferred. Historical estimates are not treated as current resources by the Company.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resource will be converted into mineral reserves. Resources are stated as contained within a single potentially economic open pit using a 0.5 oz/t silver cut-off for oxide and a 0.8 oz/t silver equivalent cut-off for sulfide. Pit optimization used silver, lead, and zinc prices of US$31.08/oz, US$0.94/lb, and US$0.88/lb respectively. A 4% NSR royalty was applied. Oxide recovery of 68.6% silver; sulfide recovery of 85% for silver, lead, and zinc. Qualified Persons: J.B. Pennington, M.Sc., C.P.G. (SRK) and W.M. Martin, M.Sc., C.P.G. (JBR). Historical estimates are not treated as current resources by Americore.
A stockpile from 1987–89 mining remains on the property, containing an estimated 782,769 ounces of silver across oxide and sulfide fractions.
Wide, consistently mineralized intervals along the Trinity Fault zone — geometry consistent with the style typical of bulk-tonnage, open-pit deposits. Higher-grade internal zones offer upside for selective mining.
A longitudinal section through the pit highlights the interpretation that many of the historical holes are too shallow. Two key intercepts — both terminated at the bottom of hole — confirm the mineralized system extends well below the depth of existing drilling, representing a significant untested target.
Long Section Looking NW — silver grade colour zonation. The circled area marks holes stopped in significant mineralization, confirming the system remains open to depth.
Core drilling within and adjacent to the historical pit confirms mineralization continuity and high-grade zones at depth.
