Staking of the Huntington-Whitman Gold Project, Nevada

Initial US gold project staked; further Nevada and Arizona staking underway

London, New York, 09 June 2026 - London BTC Company Limited ("Company") (BTC: LSE, VINZF: OTCQB), the London Stock Exchange main market-listed Bitcoin mining and treasury company with bitcoin mining operations across North America, is pleased to announce that the Company has staked 111 mineral claims at the Huntington-Whitman Gold-Silver Project (the "Project") in Humboldt County, Nevada, USA, by its wholly-owned US subsidiary Tethered Gold LLC. The staking of this exciting gold project in the heart of Nevada's premier gold province marks the Company's first project under the Company's previously announced US gold hedging strategy and the first cornerstone of a planned gold portfolio expansion in the USA.

"This is an extraordinary project for us, that sits amongst some incredibly large gold mines in the heart of Nevada's gold production." said David Lenigas, the Company's Chairman. "I see this project as adding significant value towards our gold hedge in short order and I am hoping to have further updates in the coming weeks."

·    Initial US gold project for the Company, staking 111 mineral claims covering 2,293 acres (9.3 km²) in the historically productive Humboldt County gold district of Nevada.

·    Nevada was ranked the #1 mining jurisdiction in the world in the Fraser Institute's 2025 Annual Survey of Mining Companies.

·    London BTC now joins major gold producers by being located near Barrick Gold and Newmont Corporation, who operate Twin Creeks and Turquoise Ridge Gold Mines within 35 miles (56 km) (see Figure 1).

·    The Project is strategically located 30 km north of Winnemucca, Nevada, within a region of world-class gold deposits, providing reliable access, a local workforce and mining services.

·    Huntington-Whitman sits 3 miles (5 km) from the Sleeper Mine (with endowment of 3.6 Moz gold & 23.5 Moz silver, Paramount Gold Nevada, NYSE: PZG), and 0.75 miles (1.2 km) from the historic Jumbo Deposit, which is recorded as the largest historical producer in the district.

·    Huntington-Whitman is an underexplored extension to the proximal Jumbo Mine (active 1935 - 50s), with historic ore grades reported at 1.5 oz/t Au (~47 g/t Au) with bonanza veins reporting up to 26.4 oz/t Au (822 g/t Au).
