Gold Hedging Strategy Update

Extensive gold working identified at Chance Gold Mine in Western Australia

London, New York, 5 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 on the recent geological site visit to the Chance Gold Mine in Western Australia.

The Company recently announced that it had entered a call option to acquire the Chance Gold mine as part of the Company's strategy to hedge against Bitcoin volatility.

The historic Chance Gold Mine is located approximately 4 km south of the historic 2.6Moz Copperhead Gold Mine near the town of Bullfinch in the Western Australian Goldfields. 

The site visit  to the Chance Gold Mine, which has reported historic production in the 1930's of gold ore grading 9.4 grams per tonne of gold (g/t Au), saw clear evidence of extensive old workings over considerable distances, as shown in figures 1, 2 and 3. Forty (40) rock chip samples have been collected from the site and are in the laboratory in Perth for gold and multi-element analysis. Refer to figure 4 for selection of rock chip samples taken from site.

David Lenigas, Chairman of London BTC Company Limited, comments:

"We believe this is very exciting for shareholders. The geological site visit at the Chance Mine clearly shows evidence of extensive historical gold workings over a significant distance and good widths in a prime gold jurisdiction in Western Australia. I have personally inspected of the rock samples before they were sent to the assay lab and I'm optimistic we could see some good gold grades returned. We now eagerly await the assay results from the Perth laboratory to initiate next steps. A pleasing aspect of this project and its attraction, is the lack of visible modern exploration techniques on this area, especially considering that it is so close to the 2.6 million-ounce Copperhead Gold Mine. Herein lies the value-add opportunity for London BTC. We aim to elevate the value of this asset by using cost-effective and modern-day exploration techniques to prioritise drill targets. If we can achieve some high-grade drill intercepts, the value of these tenements will potentially rise significantly and thereby proving that the gold hedge is a great way to mitigate Bitcoin volatility."

Hewie Rattray, CEO of the Company stated:

"The gold hedging strategy delivers an active approach to asset allocation, with a diversified plan for risk mitigation. While we remain long-term and highly enthusiastic stakeholders in Bitcoin as a strategic treasury asset, we also recognise that market conditions require active balance sheet management. The selective conversion of a portion of our Bitcoin holdings enables us to advance our gold hedging strategy, which we believe enhances the Company's resilience and long-term prospects. London BTC Company is very bullish for the long-term prospects for Bitcoin, and we remain fully committed to our North American Bitcoin miner roll-out and building a bigger Bitcoin treasury."

In addition, the Company advises that the 30-day exclusivity period for Call Option to acquire the tenements (as announced on 30 January 2026) has been extended by mutual agreement of both parties until the gold assay results have been received back from the laboratory from the rock chip samples.

The Company also advises it has converted 5.99 of its Bitcoin it holds in treasuries to US dollars which has realised a total of US$474,409 at an average Bitcoin price of US$79,167 per Bitcoin, to deploy towards the gold hedging strategy - a premium above current Bitcoin price. These funds will be drawn upon to fund the gold deals that match the Company's hedging objectives and for general working capital and operating costs. As at the date of this announcement, the Company holds a total of 80.2603 Bitcoin within its treasury holdings.

The Company advises that has a strong balance sheet, no external debt and 1,048 Bitcoin miners producing Bitcoin in North America at hosting centres in the US in Indiana, Iowa, Nebraska, Texas and Labrador (Canada). The Company plans to add to the mining fleet in 2026 and is continually assessing the time and cost implications/benefits in doing so.

In addition to this initial gold hedge deal in Australia, the Company advises that it is also establishing a gold arm in the US and will be active in staking prospective gold acreage in Nevada and California and we anticipate owning our first US ground within the next month.
