Fortitude Mining Holdings has expanded its credit facility with Digital Currency Group (DCG) from $26 million to $50 million, giving the Zcash-focused mining company approximately $31 million in remaining borrowing capacity. The company said the additional capital will support mining equipment purchases, facility acquisitions, new construction and infrastructure expansion.
Fortitude Plans to Sell ZEC for Mining Expansion
The amended agreement gives DCG the option to fund future loans in ZEC instead of U.S. dollars. Fortitude currently expects the remaining approximately $31 million of availability to be funded in ZEC, with the loans still denominated and repayable in dollars based on the value of the cryptocurrency when transferred.
Fortitude said it plans to liquidate all ZEC received under the facility through one or more market transactions. The first approximately $7 million of remaining availability is expected to be drawn before the end of September and used to fund payments related to the company’s previously announced purchase of 9,000 Zcash mining machines.
That structure creates an important distinction for the Zcash market. Although the financing is being provided in ZEC, Fortitude does not intend to retain those coins as a treasury asset. Instead, the company plans to convert them into cash to finance capital expenditure and operating requirements.

The new funding comes as Fortitude continues to expand its physical mining footprint. The company recently completed a 12.5-megawatt facility in Prosser, Nebraska, while its Grand Island, Nebraska facility has also been energized with 12 megawatts of power capacity.
Fortitude also agreed to purchase 9,000 Bitmain Antminer Z15 Pro units, adding roughly 7.5 GSOL/s of Zcash mining capacity when deployed. The machines are expected to arrive in the fourth quarter, making the new financing particularly relevant to the company’s planned fleet expansion.
The credit facility was originally signed on June 1, 2026 and allows borrowing for up to 18 months. It is secured by certain equipment and, where elected by DCG, real estate acquired with loan proceeds, alongside customary covenants and mandatory prepayment provisions.
Zcash Mining Push Moves Toward Public Markets
The financing expansion is also tied to Fortitude’s broader plan to become a publicly traded Zcash mining company. Fortitude and HeartSciences announced a proposed business combination earlier this year, with the combined company expected to operate under the Fortitude name and potentially trade on Nasdaq under the ticker TUDE if the transaction closes.
HeartSciences said in September that the proposed transaction remains on track for the fourth quarter of 2026, subject to customary closing conditions and shareholder approval. It also highlighted Fortitude’s 9,000-machine purchase and recent infrastructure additions as developments since the combination was announced.
Fortitude’s expansion comes with a growing focus on scale and vertically integrated infrastructure. The company describes its strategy as combining self-mining, owned data centers, power contracts and infrastructure development rather than relying solely on third-party hosting.

The company has also become a significant Zcash miner. Fortitude reported that it mined approximately 72,696 ZEC during the six months ended June 30, representing about 28% of total Zcash network production during that period, according to HeartSciences.
For ZEC holders, the financing arrangement introduces two opposing considerations. Greater Fortitude mining capacity could increase institutional infrastructure around Zcash, while the planned sale of ZEC received from DCG could create additional market supply when those transactions occur. The actual market impact will depend on the size, timing and execution of the sales.

Fortitude also said DCG could provide additional ZEC funding for capital requirements and growth initiatives through fiscal 2027. However, these are forward-looking plans rather than completed transactions, and the company cautioned that Zcash volatility, regulatory uncertainty and the proposed HeartSciences transaction could affect its plans.
The latest financing therefore gives Fortitude more capital flexibility as it prepares for a major expansion of its Zcash mining operation. With new machines, additional power infrastructure and a potential Nasdaq listing ahead, the company is positioning itself for a larger role in the Zcash mining market while relying on the sale of funded ZEC to finance that growth.
