Further to the announcement of 11 September relating to the Company's international expansion ambitions, Hamak Gold plc (LSE: HAMA / OTCQB: HASTF), a company combining traditional gold exploration in Africa with a Digital Asset Treasury Management strategy, is pleased to announce the appointment of Brittany Kaiser as the second member of Hamak Gold's Advisory Board, alongside founding member Dr. Arthur Laffer.

The purpose of this Advisory Board is to provide proprietary consultative guidance and sector expertise to the Board of Directors as the Company continues to expand its strategy of pursuing gold exploration in Africa, accompanied by a Bitcoin Treasury Management policy.

Brittany Kaiser is a leading global authority on digital asset rights, data protection and blockchain technologies. She was a co-founder of one of the world's largest bitcoin companies, Gryphon Digital Mining (now American Bitcoin, Nasdaq: ABTC) and was recently appointed as CEO of another digital asset treasury company AlphaTON Capital (Nasdaq: ATON). She is best known in the UK as a whistleblower in the Cambridge Analytica case and she is the co-founder of the Own Your Data Foundation. Ms. Kaiser has served as a strategic advisor to leading multi-national technology companies, governments, and international organisations on data ethics, Web3 infrastructure, and digital sovereignty.

Brittany Kaiser, commented:

"I'm absolutely delighted to have joined the Advisory Board of Hamak, alongside the eminent Dr. Arthur Laffer. I look forward to working with the management team; using my knowledge, experience and global relationships to enhance the Company in standing amongst its peers and pursuing its twin gold and BTC treasury objectives."

Nick Thurlow, Chairman of Hamak Gold Ltd, added:

"The Board of Hamak is very pleased to welcome Brittany to the Advisory Board. In discussions with her before this appointment, it was clear she will add valuable insights to Hamak's strategy. Digital assets are a reality of the modern world and bringing her experience from both Gryphon and now AlphaTON, we have a very valuable resource to advise us on the next steps of enhancing shareholder value through pursuing our dual strategy of gold exploration and Bitcoin Treasury Management.

"As part of its commitment to transparency and shareholder engagement, the Company will shortly announce a series of investor presentations and meeting dates where I will outline the strategic roadmap of Hamak Gold."

About Hamak Gold Limited

Hamak Gold Limited (LSE: HAMA) is a UK listed company focussed on gold exploration in Africa and with a strategy of pursuing a BTC/ crypto treasury management policy. Through its LSE main board and OTCQB listings investors underweight crypto can get professional exposure to this asset class.

Important Notice

The Company maintains some of its treasury reserves and surplus cash in Bitcoin, a form of cryptocurrency. The Company is not authorised or regulated by The Financial Conduct Authority (FCA) and Bitcoin investments are generally not subject to regulation by the FCA or otherwise in the United Kingdom.  Neither the Company nor investors in the Company's shares are protected by the UK's Financial Ombudsman Service or the Financial Services Compensation Scheme.

However the FCA considers Bitcoin investments to be high-risk. The value of Bitcoin can go up as well as down, leading to fluctuations in the value of the Company's Bitcoin holdings, and the Company may not be able to realise its Bitcoin holdings for the same amount it paid to acquire them, or even for the value the Company currently attributes to its Bitcoin positions.

The Company's Board of Directors have identified the following risks in relation to the holding of Bitcoin, which are not exhaustive:

•           The value of Bitcoin can be highly volatile, with its value falling as quickly as it rises. Investors in Bitcoin must be prepared to lose all money invested.

•           The Bitcoin market is largely unregulated. There is a risk of losing money due to factors such as cyber-attacks, financial crime, and counterparty failure.

•           The Company may not be able to sell its Bitcoin at will. The ability to sell Bitcoin depends on various factors, including the supply and demand in the market at the relevant time. Operational failings such as technology outages, cyber-attacks, and comingling of funds could cause unwanted delays.

•           Cryptoassets carry a perception of fraud, money laundering, and financial crime.

An investment in the Company is not an investment in Bitcoin itself, but prospective investors in the Company are encouraged to conduct their own research before investing and should be aware that they will have indirect exposure to the high-risk nature of cryptoassets, including their volatility, and could therefore sustain large or total losses of their investment.
