Formation of Gold Exploration Subsidiaries

London, New York 11 March 2026 - London BTC Company Limited ("Company") (BTC: LSE, VINZF: OTCQB), the London Stock Exchange Main Market-listed bitcoin mining and treasury company with mining operations across North America, is pleased to update shareholders that it has incorporated two wholly owned subsidiaries to support the evaluation of gold exploration and mineral claim staking opportunities as part of the Company's strategy to introduce gold alongside its Bitcoin treasury with the sole aim of acting as a hedge within the broader monetary system, intended to support the core operations of the Company of mining and accumulating Bitcoin.

The subsidiaries are:

Tethered Gold Pty Ltd, incorporated in Australia

Tethered Gold LLC., incorporated in the State of Nevada, United States

These entities have been established to provide a corporate structure through which the Company may pursue opportunities related to gold exploration, claim staking, and early-stage project development in established mining jurisdictions.

Australia and North America represent two of the world's most active and transparent gold exploration regions, with well-defined regulatory frameworks governing mineral claim staking and exploration licensing.

The Board believes that maintaining dedicated subsidiaries in these jurisdictions allows the Company to rapidly evaluate and secure prospective gold exploration rights, and to structure potential partnerships, joint ventures, or project-level investments where appropriate.

Gold has historically served as a store of value alongside Bitcoin, and the Board believes that selective exposure to early-stage gold opportunities provides a complementary hard-asset dimension to the Company's broader strategy.

The Company confirms that no material acquisitions or binding agreements have been entered into at this time, and further announcements will be made as appropriate.

Hewie Rattray, CEO of the Company stated.

"Alongside our Bitcoin treasury strategy, we see selective exposure to gold opportunities as a logical extension of our focus on scarce hard assets. Gold has historically acted as a hedge within the broader monetary system, and the creation of Tethered Gold in Australia and Nevada provides the Company with a platform to evaluate and secure gold exploration opportunities in two of the most active mining regions in the world."

The directors of London BTC Company Limited accept responsibility for this announcement.
