London BTC Company targets antimony potential across Nevada exploration portfolio

London BTC Company Ltd (LSE:BTC, OTCQB: VINZF) is expanding the scope of its Nevada exploration strategy to include antimony, adding exposure to the US-designated critical mineral alongside the gold and silver potential already identified across its growing project portfolio.

The company's antimony will now form part of ongoing exploration targeting in Nevada, where London BTC has assembled a portfolio of early-stage precious metals projects through its wholly owned US subsidiary, Tethered Gold LLC.

The move broadens a strategy that has so far concentrated on gold and silver, with recent work producing high-grade surface results from several projects.

At the Amonett-Frank Gold-Silver Project in Pershing County, recent assays returned gold grades of up to 143.1 grams per tonne (g/t), the highest recorded to date across London BTC’s US portfolio.

Black Star has also returned surface assays of up to 16.23 g/t gold and 50.5 g/t silver, with mineralisation identified across 2 target areas separated by around 2.5 kilometres.

London BTC has been progressively building its Nevada holdings during 2026, targeting historically worked areas with limited modern exploration.

Its portfolio includes Amonett-Frank, Black Star, Huntington-Whitman and Teep, with fieldwork focused on geological mapping, systematic surface sampling and defining targets suitable for drilling.
