CG’s mining subsidiary, Fortitude Mining, announced the purchase of 9,000 Bitmain Antminer Z15 Pro miners for Zcash (ZEC) mining. The total transaction amount was approximately $31.5 million, with a unit price of $3,499. The equipment will be delivered in two batches: the first batch of 3,000 units will arrive in October, and the remaining 6,000 units will be delivered and deployed in November.

The increase in hashrate is staggering, expanding the entire network’s hashrate by nearly 35% in one go.

According to Bitmain’s official specifications, a single Antminer Z15 Pro has a standard hashrate of 840 KSol/s. Once all 9,000 Z15 Pro miners are online, they will add a total of 7.56 GSol/s of mining hashrate to Fortitude.

As of the end of July 2026, data from network hashrate tracking platforms such as CoinWarz showed that Zcash’s total network hashrate was only in the range of 21–22 GSol/s. The deployment of these new mining machines will directly add 34%–36% of the Zcash network’s hashrate, averaging approximately 35%. A single company’s expansion can significantly alter the hashrate landscape of an entire privacy blockchain.

In terms of the company’s own production capacity, Fortitude mined 72,696 ZEC in the first half of 2026, accounting for 28% of the total ZEC production during the same period, with an average daily output of approximately 402 ZEC. The deployment of the new equipment will further and significantly expand the scale of ZEC mining.

Management remains bullish on Zcash: Now is the golden time to invest in privacy Coin mining.

In an official statement, Fortitude CEO Andrea Childs stated that this massive purchase is direct evidence of the company’s long-term confidence in the Zcash network’s value. Zcash is currently at a completely different stage of development than Bitcoin. The Bitcoin mining industry is highly mature and the market is nearing saturation; however, the Zcash mining sector still presents a huge window of opportunity, making now the best time to invest in Zcash. Our vertically integrated, full-chain layout (own mining farms, power, and operations) allows us to fully enjoy the benefits of Zcash’s continued growth. “

Striving for a Nasdaq Listing, core business tied to Zcash.

This large-scale purchase aligns with its Nasdaq listing plans. Fortitude is pushing forward with its merger with HeartSciences Inc., a transaction expected to be finalized in the second half of 2026. The ticker symbol will be TUDE, with DCG as the major shareholder. Currently, Fortitude’s revenue is highly dependent on Zcash; in the first quarter, 61% of its mining revenue came from ZEC, while Bitcoin mining revenue accounted for only 36%, indicating a significant shift in the company’s strategic focus towards privacy coins. This expansion of mining equipment will further solidify its position as a leading global Zcash miner, creating a rare pure privacy coin mining company to list on the US stock market.
