Fortitude Mining Holdings has increased its revolving credit facility with Digital Currency Group from $26 million to $50 million, with approximately $31 million in borrowing capacity still available.
The original facility was entered into on June 1, 2026, permitting borrowings for up to 18 months. The expanded commitment is secured by a first-priority lien on certain equipment and real property acquired with the loan proceeds.
Under the terms of the agreement, Digital Currency Group has the option to fund future loans in Zcash (ZEC) rather than U.S. dollars, although all loans remain denominated and repayable in USD. Fortitude expects the remaining $31 million in commitments to be funded in ZEC, and the company intends to liquidate all ZEC received via market transactions.
About $7 million remaining under the initial commitment is anticipated to be drawn before the end of September and funded in ZEC.
The borrowed funds will support Fortitude's Zcash mining operations, including payments for previously announced orders of 9,000 Zcash mining machines, mining facility acquisitions, greenfield construction, infrastructure expansion, and capital requirements through fiscal year 2027. The company noted that additional funding in ZEC may be available from Digital Currency Group.
Fortitude, which is currently wholly owned by Digital Currency Group, operates as a vertically integrated digital asset mining platform focused on Zcash.
Separately, the company is advancing a proposed business combination with HeartSciences Inc. (NASDAQ:HSCS). Upon completion of the transaction, Fortitude is expected to begin trading under the ticker symbol TUDE.
