Fortitude Mining Holdings announced a letter of intent with BITMAIN Technologies on October 6 for priority access to next-generation Zcash mining equipment. The arrangement includes a non-binding commitment to purchase as much as $100 million of hardware that has not yet been released. It marks another step in Fortitude’s expansion around Zcash, linking its mining strategy to the availability of a new equipment generation and the financing needed to deploy it.

The company reported approximately 4.7 GSol/s of operating Equihash hashrate and more than 60 megawatts of contracted power capacity across seven U.S. sites. Its earlier July agreement covered 9,000 Antminer Z15 Pro machines for approximately $31.5 million. The new letter adds a separate potential equipment allocation, rather than confirming that the entire proposed $100 million purchase has already been completed or that the unreleased machines are currently operating.

Fortitude also increased its credit facility with parent Digital Currency Group to $70 million from $50 million. The letter of intent requires a refundable deposit of $20 million, equivalent to 20% of the proposed commitment. These arrangements connect the hardware plan with available funding. For a mining business, the timing of equipment delivery matters alongside power access, since purchased machines contribute to production only after installation and commissioning at suitable facilities.

The announcement gives Fortitude a route to reserve future hardware while continuing to build its existing fleet. Its commercial effect will depend on final purchase terms, equipment specifications and deployment costs. Zcash mining economics also change with the token’s price and competition for block rewards. The October milestone is the supply arrangement and financing expansion, with actual delivery and operating performance needed to measure how much additional production the plan ultimately creates.
