MercurityFintech’s Chaince Securities to Advise U.S Next-Generation Mining Company on Gold Asset Tokenization in Central America and NorthwesternArgentina

New York, NY, Sept. 24, 2025 (GLOBE NEWSWIRE) — Mercurity Fintech Holding Inc. (the “Company,” “we,” “us,” “Mercurity Fintech,” or “MFH”) (Nasdaq: MFH), a blockchain-powered fintech group and member of the Russell 2000 Index, today announced that its wholly owned subsidiary Chaince Securities, LLC (“Chaince Securities”), a U.S.-based broker-dealer, has entered into an advisory agreement with a U.S. mining company, to provide specialized tokenization consulting services in connection with a gold mining project in Central America and Northwestern Argentina.

Northwestern Argentina and Central America represent geologically prospective gold mining regions and remain comparatively underexplored for gold, presenting opportunities for modern exploration and innovative financing solutions.

Under the advisory agreement, Chaince Securities will provide comprehensive blockchain tokenization advisory services, including:

– Asset Structuring: Designing frameworks to tokenize both physical gold reserves and future production-linked assets.

– Technology & Compliance: Developing instruments designed to comply with applicable securities regulations, supported by smart contract frameworks that facilitate on-chain rights enforcement with off-chain verification.

– Investor Protection: Implementing asset lock models, audit trail mechanisms, and whitelisting structures to ensure transparency and security of tokenized assets.

– Market Access: Connecting the gold-backed tokens with institutional-grade RWA (Real-World Assets) ecosystems and compliant marketplaces worldwide.

StrategicSignificance

This advisory agreement marks a major step for MFH in advising on the digitization of tangible real-world assets. Northwestern Argentina is a resource-rich mining region, known for its abundant gold, lithium, and rare metal reserves, and has long attracted international mining and investment capital. Through this advisory engagement, MFH aims to support the development of innovative financing solutions.

“We believe that the tokenization of real-world assets such as gold will be a defining trend for the future of capital markets,” MFH’s Chief Executive Officer Shi Qiu commented. “By combining the transparency and compliance of blockchain with the fundamentals of traditional resource industries, we aim to support the development of new, secure, traceable, and more liquid investment solutions for global investors.”
