London Btc Company Limited Stakes 36 Mineral Claims At Black Star Gold-Silver Project in Nevada and Reports High-Grade Gold and Silver Discovery
London BTC Company Limited had staked 36 mineral claims at the Black Star Gold-Silver Project in Nevada, USA. Results from initial due diligence rock chip samples collected indicate the discovery of high-grade gold at surface up to 16.23 grams per tonne (0.52 oz/t Au) and up to 50.5 g/t silver (1.62 oz/t Ag). Sampling from surface at Black Star has already provided evidence of high-grade gold mineralisation, with five of the nine mineralised samples grading above 8 g/t gold across two highly prospective target areas. Black Star is the fourth project staked and the third project in the strategic Northern Nevada region, sitting just 16 miles from the 16.4 million ounce Hycroft Mine. Results from due diligence rock chip samples collected by Schiehallion Consulting in 2026 returned high-grade gold results over some of the historical workings, including: BTCRK110, 16.23 g/t Au, 49 g/t Ag; BTCRK109, 14.39 g/t Au, 35.4 g/t Ag; BTCRK107, 10.13 g/t Au, 33 g/t Ag; BTCRK100, 8.26 g/t Au, 50.5 g/t Ag; BTCRK111, 8.17 g/t Au, 7.9 g/t Ag; BTCRK108, 3.76 g/t Au, 14.5 g/t Ag; BTCRK103, 2.16 g/t Au, 22.8 g/t Ag; BTCRK112, 1.69 g/t Au, 6.3 g/t Ag; BTCRK099, 1.53 g/t Au. Black Star is the Company's fourth US gold project, staking 36 mineral claims covering 744 acres (3km2) in the historically productive Trengo District, Pershing County, Nevada. Two mineralised areas have been identified across 2.5km, each sampled over 50 m traverses. The style of mineralisation indicates a hydrothermal system. The presence of tourmaline together with geochemistry from 1980s USGS samples produces an intrusion-related signature, suggesting a proximal fertile intrusion (USGS, MRDS-10047484). The high-grade quartz networks form a primary target, and the interpreted intrusion provides a secondary target with potential for bulk-tonnage mineralisation at depth. The primary target contains historical workings, including mine shafts, adits and trenches. Light rail infrastructure around the largest mine shaft suggests historical extraction of ore. The project geology consists of a major boundary between metavolcanics and granodiorite; extensive quartz veins exist immediately proximal and distal to the contact (USGS, MRDS-10047484). The definition of this contact is of high economic interest to the exploration teams. A review of available databases and technical literature identified small-scale mining activity in the 1930s and a small number of exploration trenches from the 1980s (USGS, MRDS Records). There is no public record of modern or systematic exploration. The Black Star Project is being actively expanded by further staking through the Company's technical adviser, Schiehallion Consulting. The Black Star Gold-Silver Project constitutes the fourth project under the Company's US gold strategy, joining the Amonett-Frank and Huntington-Whitman projects in northern Nevada and the Teep project in southern Nevada. Black Star is the Company's third project in northern Nevada and its second in Pershing County, consolidating a regional portfolio around established mining infrastructure, sealed highways and an experienced local workforce. The Project sits within a global tier 1 gold producing region. Nevada accounts for the majority of United States gold output and consistently ranks among the top five gold producing jurisdictions globally (USGS, Mineral summaries, 2026). Northern Nevada hosts a dense cluster of major, mid-tier and junior gold producers operating proximal to Black Star, providing a strong foundation of mining services, contractors, drilling providers, laboratories and toll infrastructure. The project sits 16 miles (26 km) from the Hycroft Mine (16.4 Moz Au & 562.6 Moz Ag contained from M&I), and builds on the Northern Nevada portfolio consisting of Huntington-Whitman, Amonett-Frank and the newly staked Black Star project. Hycroft Mine, holds 16.4 Moz Au and 562.6 Moz Ag with combined measured and indicated resources of 1,530 Mt @ 0.333 g/t Au (Hycroft Mining, 2026). Sleeper Mine, has reported production (1986-1996) of 1.7 Moz Au and 2.3 Moz Ag with current measured and indicated resources consist of a total of 163.2 Mt @ 0.361 g/t Au and 4.05 g/t Ag for 1.9 Moz Au and 21.2 Moz Ag (, 2023), owned by Paramount Gold Nevada, NYSE: PZG. Sandman Project, measured and indicated resources consist of a total of 8 Mt @ 1.17 g/t for 272 koz Au (Borealis Mining Company, 2026), owned by Borealis Mining Company, TSX: BOGO. Goldbanks Au Project, holds an endowment of 2.56 Moz Au and 7.47 Moz Ag with current Proven and Probable Mineral Reserves consisting of a total of 166 Mt @ 0.48 g/t Au (Stone, 2010), Kinross U.S., NYSE: KGC. Conducted as part of the Company's wider portfolio expansion strategy, the Company's geological consultant, Schiehallion Consulting, completed due diligence over the Black Star Project in June 2026. A total of 19 rock chip samples were collected by a qualified geologist and submitted for photon assay analysis at MSALABS. Sample highlights are provided below: Western Black Star: BTCRK110, 16.23 g/t Au, 49 g/t Ag; BTCRK109, 14.39 g/t Au, 35.4 g/t Ag; BTCRK107, 10.13 g/t Au, 33 g/t Ag; BTCRK111, 8.17 g/t Au, 7.9 g/t Ag; BTCRK108, 3.76 g/t Au, 14.5 g/t Ag; BTCRK112, 1.69 g/t Au, 6.3 g/t Ag. Eastern Black Star: BTCRK100, 8.26 g/t Au, 50.5 g/t Ag; BTCRK103, 2.16 g/t Au, 22.8 g/t Ag; BTCRK099, 1.53 g/t Au. MSALABS dried, crushed and pulverised the samples, which were then separated into 500g jars. Utilising Chrysos Corporation's PhotonAssay™ method, results were obtained within days of submission. PhotonAssay™ holds a lower detection limit of 0.015 ppm. Samples were routinely submitted for Fire Assay as part of follow-up QA/QC to confirm the validity of high-grade results. The Project is comprised of 36 unpatented mineral claims over 744 acres (3 km²). The staked ground focuses on the historically targeted geological contact between metavolcanics and granodiorite. The contact is targeted by shafts, adits and prospect pits. A review of government databases, technical literature and historical company reports identified limited follow-up exploration since the 1980s (USGS, MRDS Records).
